2025-05-11 06:23:03Past week summary
From a Self Custody for Organizations perspective, after analyzing the existing protocols (Cerberus, 10xSecurityBTCguide and Glacier) and reading a bunch of relates articles and guides, have wrapped to the conclusion that this format it is good to have as reference. However, something else is needed. For example, a summary or a map of the whole process to provide an overview, plus a way to deliver all the information and the multy-process in a more enjoyable way. Not a job for this hackathon, but with the right collaborations I assume it's possible to: - build something that might introduce a bit more quests and gamification - provide a learning environment (with testnet funds) could also be crucial on educating those unfamiliar with bitcoin onchain dynamics.
Have been learning more and playing around practicing best accessibility practices and how it could be applied to a desktop software like Bitcoin Safe. Thanks to @johnjherzog for providing a screen recording of his first experience and @jasonb for suggesting the tools to be used. (in this case tested/testing on Windows with the Accessibility Insights app). Some insight shared have been also applied to the website, running a full accessibility check (under WCAG 2.2 ADA, and Section 508 standards) with 4 different plugins and two online tools. I recognize that not all of them works and analyze the same parameters, indeed they complement each other providing a more accurate review.
For Bitcoin Safe interface improvements, many suggestions have been shared with @andreasgriffin , including: - a new iconset, including a micro-set to display the number of confirmed blocs for each transaction - a redesigned History/Dashboard - small refinements like adding missing columns on the tables - allow the user to select which columns to be displayed - sorting of unconfirmed transactions - Defining a new style for design elements like mempool blocks and quick receive boxes You can find below some screenshots with my proposals that hopefully will be included in the next release.
Last achievement this week was to prepare the website https://Safe.BTC.pub, the container where all the outcomes f this experiment will be published. You can have a look, just consider it still WIP. Branding for the project has also been finalized and available in this penpot file https://design.penpot.app/#/workspace?team-id=cec80257-5021-8137-8005-eab60c043dd6&project-id=cec80257-5021-8137-8005-eab60c043dd8&file-id=95aea877-d515-80ac-8006-23a251886db3&page-id=132f519a-39f4-80db-8006-2a41c364a545
What's for next week
After spending most of the time learning and reading material, this coming week will be focused on deliverables. The goal as planned will be to provide: - Finalized Safe₿its brand and improve overall desktop app experience, including categorization of transactions and addresses - An accessibility report or guide for Bitcoin Safe and support to implement best practices - A first draft of the Self-Custody for Organizations guide/framework/protocol, ideally delivered through the website http://Safe.BTC.pub in written format, but also as FlowChart to help have an overview of the whole resources needed and the process itself. This will clearly define preparations and tools/hardwares needed to successfully complete the process.

2024-01-14 13:55:28Bitcoin, not you
Bitcoin is not here to delight you. Bitcoin doesn't exist so you can receive money and trustlessly verify that you received money in your own node, which you use. Bitcoin is not about your desire of being "self-sovereign" and "your own bank". Bitcoin is a gift from God that will bring the end of all inflation, all its other characteristics are secondary.
Bitcoin is not money if not for the others.

2024-01-14 13:55:28A response to Achim Warner's "Drivechain brings politics to miners" article
I mean this article: https://achimwarner.medium.com/thoughts-on-drivechain-i-miners-can-do-things-about-which-we-will-argue-whether-it-is-actually-a5c3c022dbd2
There are basically two claims here:
1. Some corporate interests might want to secure sidechains for themselves and thus they will bribe miners to have these activated
First, it's hard to imagine why they would want such a thing. Are they going to make a proprietary KYC chain only for their users? They could do that in a corporate way, or with a federation, like Facebook tried to do, and that would provide more value to their users than a cumbersome pseudo-decentralized system in which they don't even have powers to issue currency. Also, if Facebook couldn't get away with their federated shitcoin because the government was mad, what says the government won't be mad with a sidechain? And finally, why would Facebook want to give custody of their proprietary closed-garden Bitcoin-backed ecosystem coins to a random, open and always-changing set of miners?
But even if they do succeed in making their sidechain and it is very popular such that it pays miners fees and people love it. Well, then why not? Let them have it. It's not going to hurt anyone more than a proprietary shitcoin would anyway. If Facebook really wants a closed ecosystem backed by Bitcoin that probably means we are winning big.
2. Miners will be required to vote on the validity of debatable things
He cites the example of a PoS sidechain, an assassination market, a sidechain full of nazists, a sidechain deemed illegal by the US government and so on.
There is a simple solution to all of this: just kill these sidechains. Either miners can take the money from these to themselves, or they can just refuse to engage and freeze the coins there forever, or they can even give the coins to governments, if they want. It is an entirely good thing that evil sidechains or sidechains that use horrible technology that doesn't even let us know who owns each coin get annihilated. And it was the responsibility of people who put money in there to evaluate beforehand and know that PoS is not deterministic, for example.
About government censoring and wanting to steal money, or criminals using sidechains, I think the argument is very weak because these same things can happen today and may even be happening already: i.e., governments ordering mining pools to not mine such and such transactions from such and such people, or forcing them to reorg to steal money from criminals and whatnot. All this is expected to happen in normal Bitcoin. But both in normal Bitcoin and in Drivechain decentralization fixes that problem by making it so governments cannot catch all miners required to control the chain like that -- and in fact fixing that problem is the only reason we need decentralization.

2025-05-12 01:34:24สวัสดีค่ะเพื่อนๆ นักเทรดที่น่ารักทุกคน! 💕 Lina Engword กลับมาพร้อมกับการวิเคราะห์ BTCUSDT.P แบบเจาะลึกเพื่อเตรียมพร้อมสำหรับเทรดวันนี้ค่ะ! 🚀
วันนี้ 12 พฤษภาคม 2568 เวลา 08.15น. ราคา BTCUSDT.P อยู่ที่ 104,642.8 USDT ค่ะ โดยมี Previous Weekly High (PWH) อยู่ที่ 104,967.8 Previous Weekly Low (PWL) ที่ 93,338 ค่ะ
✨ ภาพรวมตลาดวันนี้ ✨
จากการวิเคราะห์ด้วยเครื่องมือคู่ใจของเรา ทั้ง SMC/ICT (Demand/Supply Zone, Order Block, Liquidity), EMA 50/200, Trend Strength, Money Flow, Chart/Price Pattern, Premium/Discount Zone, Trend line, Fibonacci, Elliott Wave และ Dow Theory ใน Timeframe ตั้งแต่ 15m ไปจนถึง Week! 📊 เราพบว่าภาพใหญ่ของ BTCUSDT.P ยังคงอยู่ในแนวโน้มขาขึ้นที่แข็งแกร่งมากๆ ค่ะ 👍 โดยเฉพาะใน Timeframe Day และ Week ที่สัญญาณทุกอย่างสนับสนุนทิศทางขาขึ้นอย่างชัดเจน Money Flow ยังไหลเข้าอย่างต่อเนื่อง และเราเห็นโครงสร้างตลาดแบบ Dow Theory ที่ยก High ยก Low ขึ้นไปเรื่อยๆ ค่ะ
อย่างไรก็ตาม... ใน Timeframe สั้นๆ อย่าง 15m และ 1H เริ่มเห็นสัญญาณของการชะลอตัวและการพักฐานบ้างแล้วค่ะ 📉 อาจมีการสร้าง Buyside และ Sellside Liquidity รอให้ราคาไปกวาดก่อนที่จะเลือกทางใดทางหนึ่ง ซึ่งเป็นเรื่องปกติของการเดินทางของ Smart Money ค่ะ
⚡ เปรียบเทียบแนวโน้มแต่ละ Timeframe ⚡
🪙 แนวโน้มตรงกัน Timeframe 4H, Day, Week ส่วนใหญ่ชี้ไปทาง "ขาขึ้น" ค่ะ ทุกเครื่องมือสนับสนุนแนวโน้มนี้อย่างแข็งแกร่ง 💪 เป้าหมายต่อไปคือการไปทดสอบ PWH และ High เดิม เพื่อสร้าง All-Time High ใหม่ค่ะ! 🪙 แนวโน้มต่างกัน Timeframe 15m, 1H ยังค่อนข้าง "Sideways" หรือ "Sideways Down เล็กน้อย" ค่ะ มีการบีบตัวของราคาและอาจมีการพักฐานสั้นๆ ซึ่งเป็นโอกาสในการหาจังหวะเข้า Long ที่ราคาดีขึ้นค่ะ
💡 วิธีคิดแบบ Market Slayer 💡
เมื่อแนวโน้มใหญ่เป็นขาขึ้นที่แข็งแกร่ง เราจะเน้นหาจังหวะเข้า Long เป็นหลักค่ะ การย่อตัวลงมาในระยะสั้นคือโอกาสของเราในการเก็บของ! 🛍️ เราจะใช้หลักการ SMC/ICT หาโซน Demand หรือ Order Block ที่ Smart Money อาจจะเข้ามาดันราคาขึ้น และรอสัญญาณ Price Action ยืนยันการกลับตัวค่ะ
สรุปแนวโน้มวันนี้:
🪙 ระยะสั้น: Sideways to Sideways Down (โอกาส 55%) ↔️↘️ 🪙 ระยะกลาง: ขาขึ้น (โอกาส 70%) ↗️ 🪙 ระยะยาว: ขาขึ้น (โอกาส 85%) 🚀 🪙 วันนี้: มีโอกาสย่อตัวเล็กน้อยก่อนจะมีแรงซื้อกลับเข้ามาเพื่อไปทดสอบ PWH (โอกาส Sideways Down เล็กน้อย สลับกับ Sideways Up: 60%) 🎢
🗓️ Daily Trade Setup ประจำวันนี้ 🗓️
นี่คือตัวอย่าง Setup ที่ Lina เตรียมไว้ให้พิจารณาค่ะ (เน้นย้ำว่าเป็นเพียงแนวทาง ไม่ใช่คำแนะนำลงทุนนะคะ)
1️⃣ ตัวอย่างที่ 1: รอรับที่โซน Demand (ปลอดภัย, รอยืนยัน)
🪙 Enter: รอราคาย่อตัวลงมาในโซน Demand Zone หรือ Bullish Order Block ที่น่าสนใจใน TF 1H/4H (ดูจากกราฟประกอบนะคะ) และเกิดสัญญาณ Bullish Price Action ที่ชัดเจน เช่น แท่งเทียนกลืนกิน (Engulfing) หรือ Hammer 🪙 TP: บริเวณ PWH 104,967.8 หรือ Buyside Liquidity ถัดไป 🎯 🪙 SL: ใต้ Low ที่เกิดก่อนสัญญาณกลับตัวเล็กน้อย หรือใต้ Demand Zone ที่เข้า 🛡️ 🪙 RRR: ประมาณ 1:2.5 ขึ้นไป ✨ 🪙 อธิบาย: Setup นี้เราจะใจเย็นๆ รอให้ราคาลงมาในโซนที่มีโอกาสเจอแรงซื้อเยอะๆ ตามหลัก SMC/ICT แล้วค่อยเข้า เพื่อให้ได้ราคาที่ดีและความเสี่ยงต่ำค่ะ ต้องรอสัญญาณ Price Action ยืนยันก่อนนะคะ ✍️
2️⃣ ตัวอย่างที่ 2: Follow Breakout (สายบู๊, รับความเสี่ยงได้)
🪙 Enter: เข้า Long ทันทีเมื่อราคาสามารถ Breakout เหนือ High ล่าสุดใน TF 15m หรือ 1H พร้อม Volume ที่เพิ่มขึ้นอย่างมีนัยสำคัญ 🔥 🪙 TP: บริเวณ PWH 104,967.8 หรือ Buyside Liquidity ถัดไป 🚀 🪙 SL: ใต้ High ก่อนหน้าที่ถูก Breakout เล็กน้อย 🚧 🪙 RRR: ประมาณ 1:3 ขึ้นไป ✨ 🪙 อธิบาย: Setup นี้เหมาะกับคนที่อยากเข้าไวเมื่อเห็นโมเมนตัมแรงๆ ค่ะ เราจะเข้าเมื่อราคา Breakout แนวต้านระยะสั้นพร้อม Volume เป็นสัญญาณว่าแรงซื้อกำลังมาค่ะ เข้าได้เลยด้วยการตั้ง Limit Order หรือ Market Order เมื่อเห็นการ Breakout ที่ชัดเจนค่ะ 💨
3️⃣ ตัวอย่างที่ 3: พิจารณา Short สั้นๆ ในโซน Premium (สวนเทรนด์หลัก, ความเสี่ยงสูง)
🪙 Enter: หากราคาขึ้นไปในโซน Premium ใน TF 15m หรือ 1H และเกิดสัญญาณ Bearish Price Action ที่ชัดเจน เช่น แท่งเทียน Shooting Star หรือ Bearish Engulfing บริเวณ Supply Zone หรือ Bearish Order Block 🐻 🪙 TP: พิจารณาแนวรับถัดไป หรือ Sellside Liquidity ใน TF เดียวกัน 🎯 🪙 SL: เหนือ High ของสัญญาณ Bearish Price Action เล็กน้อย 💀 🪙 RRR: ประมาณ 1:1.5 ขึ้นไป (เน้นย้ำว่าเป็นการเทรดสวนเทรนด์หลัก ควรใช้ RRR ต่ำและบริหารขนาด Lot อย่างเข้มงวด!) 🪙 อธิบาย: Setup นี้สำหรับคนที่เห็นโอกาสในการทำกำไรจากการย่อตัวระยะสั้นค่ะ เราจะเข้า Short เมื่อเห็นสัญญาณว่าราคาอาจจะมีการพักฐานในโซนที่ถือว่า "แพง" ในกรอบสั้นๆ ค่ะ ต้องตั้ง Stop Loss ใกล้มากๆ และจับตาดูใกล้ชิดนะคะ 🚨
⚠️ Disclaimer: การวิเคราะห์นี้เป็นเพียงความคิดเห็นส่วนตัวของ Lina เท่านั้น ไม่ถือเป็นคำแนะนำในการลงทุนนะคะ การลงทุนมีความเสี่ยง ผู้ลงทุนควรศึกษาข้อมูลเพิ่มเติมและตัดสินใจด้วยความรอบคอบค่ะ 🙏
ขอให้ทุกท่านโชคดีกับการเทรดในวันนี้ค่ะ! มีคำถามอะไรเพิ่มเติม ถามมาได้เลยนะคะ ยินดีเสมอค่ะ! 😊

2025-05-10 09:50:45Information ohne Reflexion ist geistiger Flugsand. \ Ernst Reinhardt
Der lateinische Ausdruck «Quo vadis» als Frage nach einer Entwicklung oder Ausrichtung hat biblische Wurzeln. Er wird aber auch in unserer Alltagssprache verwendet, laut Duden meist als Ausdruck von Besorgnis oder Skepsis im Sinne von: «Wohin wird das führen?»
Der Sinn und Zweck von so mancher politischen Entscheidung erschließt sich heutzutage nicht mehr so leicht, und viele Trends können uns Sorge bereiten. Das sind einerseits sehr konkrete Themen wie die zunehmende Militarisierung und die geschichtsvergessene Kriegstreiberei in Europa, deren Feindbildpflege aktuell beim Gedenken an das Ende des Zweiten Weltkriegs beschämende Formen annimmt.
Auch das hohe Gut der Schweizer Neutralität scheint immer mehr in Gefahr. Die schleichende Bewegung der Eidgenossenschaft in Richtung NATO und damit weg von einer Vermittlerposition erhält auch durch den neuen Verteidigungsminister Anschub. Martin Pfister möchte eine stärkere Einbindung in die europäische Verteidigungsarchitektur, verwechselt bei der Argumentation jedoch Ursache und Wirkung.
Das Thema Gesundheit ist als Zugpferd für Geschäfte und Kontrolle offenbar schon zuverlässig etabliert. Die hauptsächlich privat finanzierte Weltgesundheitsorganisation (WHO) ist dabei durch ein Netzwerk von sogenannten «Collaborating Centres» sogar so weit in nationale Einrichtungen eingedrungen, dass man sich fragen kann, ob diese nicht von Genf aus gesteuert werden.
Das Schweizer Bundesamt für Gesundheit (BAG) übernimmt in dieser Funktion ebenso von der WHO definierte Aufgaben und Pflichten wie das deutsche Robert Koch-Institut (RKI). Gegen die Covid-«Impfung» für Schwangere, die das BAG empfiehlt, obwohl es fehlende wissenschaftliche Belege für deren Schutzwirkung einräumt, formiert sich im Tessin gerade Widerstand.
Unter dem Stichwort «Gesundheitssicherheit» werden uns die Bestrebungen verkauft, essenzielle Dienste mit einer biometrischen digitalen ID zu verknüpfen. Das dient dem Profit mit unseren Daten und führt im Ergebnis zum Verlust unserer demokratischen Freiheiten. Die deutsche elektronische Patientenakte (ePA) ist ein Element mit solchem Potenzial. Die Schweizer Bürger haben gerade ein Referendum gegen das revidierte E-ID-Gesetz erzwungen. In Thailand ist seit Anfang Mai für die Einreise eine «Digital Arrival Card» notwendig, die mit ihrer Gesundheitserklärung einen Impfpass «durch die Hintertür» befürchten lässt.
Der massive Blackout auf der iberischen Halbinsel hat vermehrt Fragen dazu aufgeworfen, wohin uns Klimawandel-Hysterie und «grüne» Energiepolitik führen werden. Meine Kollegin Wiltrud Schwetje ist dem nachgegangen und hat in mehreren Beiträgen darüber berichtet. Wenig überraschend führen interessante Spuren mal wieder zu internationalen Großbanken, Globalisten und zur EU-Kommission.
Zunehmend bedenklich ist aber ganz allgemein auch die manifestierte Spaltung unserer Gesellschaften. Angesichts der tiefen und sorgsam gepflegten Gräben fällt es inzwischen schwer, eine zukunftsfähige Perspektive zu erkennen. Umso begrüßenswerter sind Initiativen wie die Kölner Veranstaltungsreihe «Neue Visionen für die Zukunft». Diese möchte die Diskussionskultur reanimieren und dazu beitragen, dass Menschen wieder ohne Angst und ergebnisoffen über kontroverse Themen der Zeit sprechen.
Quo vadis – Wohin gehen wir also? Die Suche nach Orientierung in diesem vermeintlichen Chaos führt auch zur Reflexion über den eigenen Lebensweg. Das ist positiv insofern, als wir daraus Kraft schöpfen können. Ob derweil der neue Papst, dessen «Vorgänger» Petrus unsere Ausgangsfrage durch die christliche Legende zugeschrieben wird, dabei eine Rolle spielt, muss jede/r selbst wissen. Mir persönlich ist allein schon ein Führungsanspruch wie der des Petrusprimats der römisch-katholischen Kirche eher suspekt.

In this video, I explore how it slowly lost its crown through decades of missed opportunities - eventually leading to creative collapse due to various bureaucratic intrigues, unforeseen technological changes and some of the jankiest UI/UX you've ever seen.

2024-01-14 13:55:28Idéia de um sistema jurídico centralizado, mas com um pouco de lógica
um processo, é, essencialmente, imagino eu na minha ingenuidade leiga, um apelo que se faz ao juiz para que este reconheça certos fatos como probantes de um certo fenômeno tipificado por uma certa lei.
imagino então o seguinte:
uma petição não é mais um enorme documento escrito numa linguagem nojenta com referências a leis e a evidências factuais espalhadas segundo a (in) capacidade ensaística do advogado, mas apenas um esquema lógico - talvez até um diagrama desenhado (ou talvez quem sabe uma série de instruções compreensíveis por um computador?) - mostrando a ligação entre a lei e os fatos e os pedidos, por exemplo:
- a lei tal diz que ninguém pode vender
- fulano vendeu cigarros
- é prova de que fulano vendeu cigarros ia foto tirada na rua tal no dia tal que mostra fulano vendendo cigarros
- a mesma lei pede que fulano pague uma multa
este exemplo está ainda muito verborrágico, mas é só um exemplo simples. coisas mais complicadas precisariam de outras formas de expressão caso queiramos evitar as longas dissertações jurídicas em voga.
a idéia é que o esquema acima vale por si. um proto-juiz pode julgá-lo como válido ou inválido apenas pela sua lógica interna.
a outra parte do julgamento seria a ligação desse esquema com a realidade externa: anexados à petição viriam as evidências. no caso, anexada ao ponto 3 viria uma foto do fulano. ao ponto 1 também precisa ser anexado o texto da lei referida, mas isto pode ser feito automaticamente pelo número da lei.
uma vez que tenhamos um esquema lógico válido um outro proto-juiz, ou vários outros, pode julgar individualmente cada evidência: ver se o texto da lei confere com a interpretação feita no ponto 1, e se a foto anexada ao ponto 3 é mesmo a foto do réu vendendo cigarro e não a de um urso comendo laranjas.
cada um desses julgamentos pode ser feito sem que o proto-juiz tenha conhecimento do resto das coisas do processo: o primeiro proto-juiz não precisa ver a foto ou a lei, o segundo não precisa ver o esquema lógico ou a foto, o terceiro não precisa ver a lei nem o esquema lógico, e mesmo assim teríamos um julgamento de procedência ou não da petição ao final, o mais impessoal e provavelmente o mais justo possível.
a defesa consistiria em apontar erros no esquema lógico ou falhas no nexo entre a realidade é o esquema. por exemplo:
- uma foto assim não é uma prova de que fulano vendeu, ele podia estar só passando lá perto.
- ele estava de fato só passando lá perto. do que é prova este documento mostrando seu comparecimento a uma aula do curso de direito da UFMG no mesmo horário.
perdoem-me se estiver falando besteira, mas são 5h e estou ainda dormindo. obviamente há vários pontos problemáticos aí, e quero entendê-los, mas a forma geral me parece bem razoável.
o que descrevi acima é uma proposta, digamos, de sistema jurídico que não se diferencia em nada do nosso sistema jurídico atual, exceto na forma (não no sentido escolástico). é também uma tentativa de compreender sua essência.
as vantagens desse formato ao atual são muitas:
- menos papel, coisas pra ler, repetição infinita de citações legais e longuíssimas dissertações escritas por advogados analfabetos que destroem a língua e a inteligência de todos
- diminuição drástica do tempo gasto por cada juiz em cada processo
- diminuição do poder de cada juiz (se cada ato de julgamento humano necessário em cada processo pode ser feito por qualquer juiz, sem conhecimento dos outros aspectos do mesmo processo, tudo é muito mais rápido, e cada julgamento desses pode ser feito por vários juízes diferentes, escolhidos aleatoriamente)
- diminuição da pomposidade de casa juiz: com menos poder e obrigações maus simples, um juiz não precisa ser mais uma pessoa especial que ganha milhões, pode ser uma pessoa comum, um proto-juiz, ganhando menos (o que possibilitaria até ter mais desses e aumentar a confiabilidade de cada julgamento)
- os juízes podem trabalhar da casa deles e a qualquer momento
- passa a ter sentido a existência de um sistema digital de processos (porque é ridículo que o sistema digital atual seja só uma forma de passar documentos do Word de um lado para o outro)
- o fim das audiências de conciliação, que são uma monstruosidade criada apenas pela necessidade de diminuir a quantidade de processos em tramitação e acabam retirandobo sentido da justiça (as partes são levemente pressionadas a ignorar a validade ou não das suas posições e fazer um acordo, sob pena de o juiz ficar com raiva delas depois)
milhares de precauções devem ser tomadas caso um sistema desses vá ser implantado (ahahah), talvez manter uma forma de julgamento tradicional, de corpo presente e com um juiz ou júri que tem conhecimento de toda situação, mas apenas para processos que chegarem até certo ponto, e assim por diante.

For generations before generative text, writers have used the em dash to hop between thoughts, emotions, and ideas. Dickens shaped his morality tales with it, Woolf’s stream-of-consciousness flowed through it, Kerouac let it drive his jazz-like prose. Today, Sally Rooney threads it through her quiet truths of the heart.
But this beloved punctuation mark has become a casualty of the algorithmic age. The em dash has been so widely adopted by AI-generated text that even when used by human hands, it begs the question: was this actually written or apathetically prompted?
The battle for the soul of writing is in full swing. And the human fightback starts here. With a new punctuation mark that serves as a symbol of real pondering, genuine daydreaming, and true editorial wordsmithery. Inspired by Descartes’ belief that thinking makes us human, the am dash is a small but powerful testament that the words you’ve painstakingly and poetically pulled together are unequivocally, certifiably, and delightfully your own.
Let's reclain writig from AI—oneam dash at time.

2024-01-14 13:55:28Carl R. Rogers sobre a ciência
Creio que o objetivo primário da ciência é fornecer uma hipótese, uma convicção e uma fé mais seguras e que satisfaçam melhor o próprio investigador. Na medida em que o cientista procura provar qualquer coisa a alguém -- um erro em que incorri mais de uma vez --, creio que ele está se servindo da ciência para remediar uma insegurança pessoal, desviando-a do seu verdadeiro papel criativo a serviço do indivíduo.

2025-05-12 01:06:27Soil moisture is one of the key factors affecting crop root development. Too much or too little moisture will have an adverse effect on root growth.
Effect of excessive moisture When there is too much soil moisture, the following problems will occur:
Inhibit root respiration: Excessive moisture will squeeze out oxygen in the soil, causing root hypoxia, thereby inhibiting root respiration, and in severe cases, it can cause root growth to stop or rot and die. Affect soil aeration: Excessive moisture will reduce soil aeration and affect the normal growth of the root system. Effect of too little moisture When there is too little soil moisture, it will also have a negative impact on the root system:
Promote root corking and self-thinning: Lack of water can cause root corking and even self-thinning, affecting the absorption capacity of the root system.
Determine whether the soil moisture is appropriate In order to ensure the healthy development of crop roots, soil moisture needs to be managed reasonably. The following methods can be used to determine whether the soil moisture is appropriate:
Touch test: Use a small shovel to dig up the soil around the root system, grab some soil with your hand and pinch it in your hand. If the soil can be kneaded into a ball and can be spread apart, the moisture content is appropriate; if it can be kneaded into a ball but cannot be spread apart, the moisture content exceeds the standard; if it cannot be kneaded into a ball, the soil is lacking in water.
Conclusion In summary, soil moisture has an important impact on the development of crop roots. Reasonable water management is essential to promote healthy root growth. By monitoring and adjusting soil moisture through appropriate methods, the normal growth and development of crops can be effectively guaranteed.

2025-05-10 05:11:27Consider the following two charts from A History of Clojure which detail the introduction and retention of new code by release for both Clojure and for Scala.
While this doesn't necessarily translate to library stability, it's reasonable to assume that the attitude of the Clojure maintainers will seep into the community. And that assumption is true.
Consider a typical Javascript program. What is it comprised of? Objects, objects, and more objects. Members of those objects must be either introspected or divined. Worse, it's normal to monkeypatch those objects, so the object members may (or may not) change over time.
Now, consider a typical Clojure program. What is it comprised of? Namespaces. Those namespaces contain functions and data. Functions may be dynamically generated (via macros), but it is extremely rare to "monkeypatch" a namespace. If you want to know what functions are available in a namespace, you can simply read the source file.

2024-01-14 13:55:28TiddlyWiki remoteStorage
TiddlyWiki is very good and useful, but since at this time I used multiple computers during the week, it wouldn't work for me to use it as a single file on my computer, so I had to hack its internal tiddler saving mechanism to instead save the raw data of each tiddler to remoteStorage and load them from that place also (ok, there was in theory a plugin system, but I had to read and understand the entire unformatted core source-code anyway).
There was also a server that fetched tiddlywikis from anyone's remoteStorage buckets (after authorization) and served these to the world, a quick and nice way to publish a TiddlyWiki -- which is a problem all people in TiddlyWiki struggle against.

2025-05-12 00:49:33Real-time monitoring of oil concentration in water The basic principle of oil in water sensor is to use the characteristic that oil will produce fluorescence under ultraviolet light, and measure the fluorescence intensity to infer the concentration of oil. The sensor uses ultraviolet light as the excitation light source to illuminate the water sample to be tested. The oil absorbs ultraviolet light and excites fluorescence. The fluorescence signal is received by the photo detector and converted into an electrical signal, and then the strength of the electrical signal is measured to determine the concentration of oil in the water sample, so as to achieve real-time monitoring of the concentration of oil in the water.
Multi-scenario water quality monitoring Water source water quality monitoring It can be used to monitor the water quality of water sources. By continuously monitoring the oil in the water source, the pollution source can be found in time, thereby ensuring the safety of drinking water and water supply.
Sewage treatment plant discharge monitoring Sewage treatment plants may produce oily wastewater in the process of treating sewage. The oil-in-water sensor can monitor the water quality of its discharge to ensure that it meets the discharge standards and avoids secondary pollution to the environment.
Monitoring of water bodies such as rivers and lakes Water bodies such as rivers and lakes may be polluted by oil substances, such as ship leakage and industrial wastewater discharge. This sensor can monitor the water quality of these water bodies, evaluate the pollution status, and provide a basis for pollution control.
Aquaculture monitoring The online oil-in-water monitor (including oil-in-water sensor) can transmit monitoring data in real time to help farmers understand the water quality. Farmers can use it to understand the oil content in the water body in real time, and reasonably release it according to the needs of fish to improve the growth rate and health level of fish; it can also timely detect abnormal conditions in the water body, such as oil pollution and bacterial growth, and take corresponding measures to avoid the occurrence of diseases and reduce breeding costs and risks; at the same time, it helps farmers better understand the growth of fish, reasonably arrange fishing time, avoid overfishing and resource depletion, and promote the sustainable use of aquatic resources.
Early warning and emergency response It has real-time monitoring and early warning functions, and can issue an alarm in time when abnormal conditions of oil substances in the water body (such as exceeding the pee-set safety threshold) are found, providing valuable time for emergency response and reducing losses caused by pollution.
Assisting scientific research The monitoring data of the sensor can be used in scientific research fields such as ecology and environmental chemistry, helping researchers to gain a deeper understanding of the distribution, migration and transformation of oil substances in water bodies, and provide a scientific basis for environmental protection and governance.
Monitoring of pollution sources and environmental changes By detecting oil substances in water bodies, the location of pollution sources and the types of pollutants can be determined, providing a basis for finding and controlling pollution sources; it can also monitor oil pollutants in water bodies to understand the impact of environmental changes on water bodies and take timely measures to protect water sources.

sudo btrfs balance start --full-balance /data
Pode demorar um pouco para espalhar os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID se ele contiver muitos dados.
Opções importantes de montagem Btrfs
Nesta seção, vou explicar algumas das importantes opções de montagem do Btrfs. Então vamos começar.
As opções de montagem Btrfs mais importantes são:
**1. acl e noacl
**ACL gerencia permissões de usuários e grupos para os arquivos/diretórios do sistema de arquivos Btrfs.
A opção de montagem acl Btrfs habilita ACL. Para desabilitar a ACL, você pode usar a opção de montagem noacl .
Por padrão, a ACL está habilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem acl por padrão.
**2. autodefrag e noautodefrag
**Desfragmentar um sistema de arquivos Btrfs melhorará o desempenho do sistema de arquivos reduzindo a fragmentação de dados.
A opção de montagem autodefrag permite a desfragmentação automática do sistema de arquivos Btrfs.
A opção de montagem noautodefrag desativa a desfragmentação automática do sistema de arquivos Btrfs.
Por padrão, a desfragmentação automática está desabilitada. Portanto, o sistema de arquivos Btrfs usa a opção de montagem noautodefrag por padrão.
**3. compactar e compactar-forçar
**Controla a compactação de dados no nível do sistema de arquivos do sistema de arquivos Btrfs.
A opção compactar compacta apenas os arquivos que valem a pena compactar (se compactar o arquivo economizar espaço em disco).
A opção compress-force compacta todos os arquivos do sistema de arquivos Btrfs, mesmo que a compactação do arquivo aumente seu tamanho.
O sistema de arquivos Btrfs suporta muitos algoritmos de compactação e cada um dos algoritmos de compactação possui diferentes níveis de compactação.
Os algoritmos de compactação suportados pelo Btrfs são: lzo , zlib (nível 1 a 9) e zstd (nível 1 a 15).
Você pode especificar qual algoritmo de compactação usar para o sistema de arquivos Btrfs com uma das seguintes opções de montagem:
- compress=algoritmo:nível
- compress-force=algoritmo:nível
Para obter mais informações, consulte meu artigo Como habilitar a compactação do sistema de arquivos Btrfs .
**4. subvol e subvolid
**Estas opções de montagem são usadas para montar separadamente um subvolume específico de um sistema de arquivos Btrfs.
A opção de montagem subvol é usada para montar o subvolume de um sistema de arquivos Btrfs usando seu caminho relativo.
A opção de montagem subvolid é usada para montar o subvolume de um sistema de arquivos Btrfs usando o ID do subvolume.
Para obter mais informações, consulte meu artigo Como criar e montar subvolumes Btrfs .
**5. dispositivo
A opção de montagem de dispositivo** é usada no sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs.
Em alguns casos, o sistema operacional pode falhar ao detectar os dispositivos de armazenamento usados em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs. Nesses casos, você pode usar a opção de montagem do dispositivo para especificar os dispositivos que deseja usar para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar a opção de montagem de dispositivo várias vezes para carregar diferentes dispositivos de armazenamento para o sistema de arquivos de vários dispositivos Btrfs ou RAID.
Você pode usar o nome do dispositivo (ou seja, sdb , sdc ) ou UUID , UUID_SUB ou PARTUUID do dispositivo de armazenamento com a opção de montagem do dispositivo para identificar o dispositivo de armazenamento.
Por exemplo,
- dispositivo=/dev/sdb
- dispositivo=/dev/sdb,dispositivo=/dev/sdc
- dispositivo=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d
- device=UUID_SUB=490a263d-eb9a-4558-931e-998d4d080c5d,device=UUID_SUB=f7ce4875-0874-436a-b47d-3edef66d3424
**6. degraded
A opção de montagem degradada** permite que um RAID Btrfs seja montado com menos dispositivos de armazenamento do que o perfil RAID requer.
Por exemplo, o perfil raid1 requer a presença de 2 dispositivos de armazenamento. Se um dos dispositivos de armazenamento não estiver disponível em qualquer caso, você usa a opção de montagem degradada para montar o RAID mesmo que 1 de 2 dispositivos de armazenamento esteja disponível.
**7. commit
A opção commit** mount é usada para definir o intervalo (em segundos) dentro do qual os dados serão gravados no dispositivo de armazenamento.
O padrão é definido como 30 segundos.
Para definir o intervalo de confirmação para 15 segundos, você pode usar a opção de montagem commit=15 (digamos).
**8. ssd e nossd
A opção de montagem ssd** informa ao sistema de arquivos Btrfs que o sistema de arquivos está usando um dispositivo de armazenamento SSD, e o sistema de arquivos Btrfs faz a otimização SSD necessária.
A opção de montagem nossd desativa a otimização do SSD.
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem de SSD será habilitada. Caso contrário, a opção de montagem nossd é habilitada.
**9. ssd_spread e nossd_spread
A opção de montagem ssd_spread** tenta alocar grandes blocos contínuos de espaço não utilizado do SSD. Esse recurso melhora o desempenho de SSDs de baixo custo (baratos).
A opção de montagem nossd_spread desativa o recurso ssd_spread .
O sistema de arquivos Btrfs detecta automaticamente se um SSD é usado para o sistema de arquivos Btrfs. Se um SSD for usado, a opção de montagem ssd_spread será habilitada. Caso contrário, a opção de montagem nossd_spread é habilitada.
**10. descarte e nodiscard
Se você estiver usando um SSD que suporte TRIM enfileirado assíncrono (SATA rev3.1), a opção de montagem de descarte** permitirá o descarte de blocos de arquivos liberados. Isso melhorará o desempenho do SSD.
Se o SSD não suportar TRIM enfileirado assíncrono, a opção de montagem de descarte prejudicará o desempenho do SSD. Nesse caso, a opção de montagem nodiscard deve ser usada.
Por padrão, a opção de montagem nodiscard é usada.
**11. norecovery
Se a opção de montagem norecovery** for usada, o sistema de arquivos Btrfs não tentará executar a operação de recuperação de dados no momento da montagem.
**12. usebackuproot e nousebackuproot
Se a opção de montagem usebackuproot for usada, o sistema de arquivos Btrfs tentará recuperar qualquer raiz de árvore ruim/corrompida no momento da montagem. O sistema de arquivos Btrfs pode armazenar várias raízes de árvore no sistema de arquivos. A opção de montagem usebackuproot** procurará uma boa raiz de árvore e usará a primeira boa que encontrar.
A opção de montagem nousebackuproot não verificará ou recuperará raízes de árvore inválidas/corrompidas no momento da montagem. Este é o comportamento padrão do sistema de arquivos Btrfs.
**13. space_cache, space_cache=version, nospace_cache e clear_cache
A opção de montagem space_cache** é usada para controlar o cache de espaço livre. O cache de espaço livre é usado para melhorar o desempenho da leitura do espaço livre do grupo de blocos do sistema de arquivos Btrfs na memória (RAM).
O sistema de arquivos Btrfs suporta 2 versões do cache de espaço livre: v1 (padrão) e v2
O mecanismo de cache de espaço livre v2 melhora o desempenho de sistemas de arquivos grandes (tamanho de vários terabytes).
Você pode usar a opção de montagem space_cache=v1 para definir a v1 do cache de espaço livre e a opção de montagem space_cache=v2 para definir a v2 do cache de espaço livre.
A opção de montagem clear_cache é usada para limpar o cache de espaço livre.
Quando o cache de espaço livre v2 é criado, o cache deve ser limpo para criar um cache de espaço livre v1 .
Portanto, para usar o cache de espaço livre v1 após a criação do cache de espaço livre v2 , as opções de montagem clear_cache e space_cache=v1 devem ser combinadas: clear_cache,space_cache=v1
A opção de montagem nospace_cache é usada para desabilitar o cache de espaço livre.
Para desabilitar o cache de espaço livre após a criação do cache v1 ou v2 , as opções de montagem nospace_cache e clear_cache devem ser combinadas: clear_cache,nosapce_cache
**14. skip_balance
Por padrão, a operação de balanceamento interrompida/pausada de um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs será retomada automaticamente assim que o sistema de arquivos Btrfs for montado. Para desabilitar a retomada automática da operação de equilíbrio interrompido/pausado em um sistema de arquivos Btrfs de vários dispositivos ou RAID Btrfs, você pode usar a opção de montagem skip_balance .**
**15. datacow e nodatacow
A opção datacow** mount habilita o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs. É o comportamento padrão.
Se você deseja desabilitar o recurso Copy-on-Write (CoW) do sistema de arquivos Btrfs para os arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatacow .
**16. datasum e nodatasum
A opção datasum** mount habilita a soma de verificação de dados para arquivos recém-criados do sistema de arquivos Btrfs. Este é o comportamento padrão.
Se você não quiser que o sistema de arquivos Btrfs faça a soma de verificação dos dados dos arquivos recém-criados, monte o sistema de arquivos Btrfs com a opção de montagem nodatasum .
Perfis Btrfs
Um perfil Btrfs é usado para informar ao sistema de arquivos Btrfs quantas cópias dos dados/metadados devem ser mantidas e quais níveis de RAID devem ser usados para os dados/metadados. O sistema de arquivos Btrfs contém muitos perfis. Entendê-los o ajudará a configurar um RAID Btrfs da maneira que você deseja.
Os perfis Btrfs disponíveis são os seguintes:
single : Se o perfil único for usado para os dados/metadados, apenas uma cópia dos dados/metadados será armazenada no sistema de arquivos, mesmo se você adicionar vários dispositivos de armazenamento ao sistema de arquivos. Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
dup : Se o perfil dup for usado para os dados/metadados, cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos manterá duas cópias dos dados/metadados. Assim, 50% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser utilizado.
raid0 : No perfil raid0 , os dados/metadados serão divididos igualmente em todos os dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, não haverá dados/metadados redundantes (duplicados). Assim, 100% do espaço em disco de cada um dos dispositivos de armazenamento adicionados ao sistema de arquivos pode ser usado. Se, em qualquer caso, um dos dispositivos de armazenamento falhar, todo o sistema de arquivos será corrompido. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid0 .
raid1 : No perfil raid1 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a uma falha de unidade. Mas você pode usar apenas 50% do espaço total em disco. Você precisará de pelo menos dois dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1 .
raid1c3 : No perfil raid1c3 , três cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a duas falhas de unidade, mas você pode usar apenas 33% do espaço total em disco. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c3 .
raid1c4 : No perfil raid1c4 , quatro cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos. Nesta configuração, a matriz RAID pode sobreviver a três falhas de unidade, mas você pode usar apenas 25% do espaço total em disco. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid1c4 .
raid10 : No perfil raid10 , duas cópias dos dados/metadados serão armazenadas nos dispositivos de armazenamento adicionados ao sistema de arquivos, como no perfil raid1 . Além disso, os dados/metadados serão divididos entre os dispositivos de armazenamento, como no perfil raid0 .
O perfil raid10 é um híbrido dos perfis raid1 e raid0 . Alguns dos dispositivos de armazenamento formam arrays raid1 e alguns desses arrays raid1 são usados para formar um array raid0 . Em uma configuração raid10 , o sistema de arquivos pode sobreviver a uma única falha de unidade em cada uma das matrizes raid1 .
Você pode usar 50% do espaço total em disco na configuração raid10 . Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid10 .
raid5 : No perfil raid5 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Uma única paridade será calculada e distribuída entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid5 , o sistema de arquivos pode sobreviver a uma única falha de unidade. Se uma unidade falhar, você pode adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir da paridade distribuída das unidades em execução.
Você pode usar 1 00x(N-1)/N % do total de espaços em disco na configuração raid5 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos três dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid5 .
raid6 : No perfil raid6 , uma cópia dos dados/metadados será dividida entre os dispositivos de armazenamento. Duas paridades serão calculadas e distribuídas entre os dispositivos de armazenamento do array RAID.
Em uma configuração raid6 , o sistema de arquivos pode sobreviver a duas falhas de unidade ao mesmo tempo. Se uma unidade falhar, você poderá adicionar uma nova unidade ao sistema de arquivos e os dados perdidos serão calculados a partir das duas paridades distribuídas das unidades em execução.
Você pode usar 100x(N-2)/N % do espaço total em disco na configuração raid6 . Aqui, N é o número de dispositivos de armazenamento adicionados ao sistema de arquivos. Você precisará de pelo menos quatro dispositivos de armazenamento para configurar o sistema de arquivos Btrfs no perfil raid6 .

2024-01-14 13:55:28P2P reputation thing
Each node shares a blob of the reputations they have, which includes a confidence number. The number comes from the fact that reputations are inherited from other nodes they trust and averaged by their confidence in these. Everything is mixed for plausible deniability. By default a node only shares their stuff with people they manually add, to prevent government from crawling everybody's database. Also to each added friend nodes share a different identity/pubkey (like giving a new Bitcoin address for every transaction) (derived from hip32) (and since each identity can only be contacted by one other entity the node filters incoming connections to download their database: "this identity already been used? no, yes, used with which peer?").
Network protocol
Maybe the data uploader/offerer initiates connection to the receiver over Tor so there's only a Tor address for incoming data, never an address for a data source, i.e. everybody has an address, but only for requesting data.
How to request? Post an encrypted message in an IRC room or something similar (better if messages are stored for a while) targeted to the node/identity you want to download from, along with your Tor address. Once the node sees that it checks if you can download and contacts you.
The encrypted messages could have the target identity pubkey prefix such that the receiving node could try to decrypt only some if those with some probability of success.
Nodes can choose to share with anyone, share only with pre-approved people, share only with people who know one of their addresses/entities (works like a PIN, you give the address to someone in the street, that person can reach you, to the next person you give another address etc., you can even have a public address and share limited data with that).
Data model
Each entry in a database should be in the following format:
internal_id : real_world_identifier [, real_world_identifier...] : tag
Which means you can either associate one or multiple real world identifier with an internal id and associate the real person designated by these identifiers with a tag. the tag should be part of the standard or maybe negotiated between peers. it can be things like
scammer
,thief
,tax collector
etc., orhonest
,good dentist
etc. defining good enough labels may be tricky.internal_id
should be created by the user who made the record about the person.At first this is not necessary, but additional bloat can be added to the protocol if the federated automated message posting boards are working in the sense that each user can ask for more information about a given id and the author of that record can contact the person asking for information and deliver free text to them with the given information. For this to work the internal id must be a public key and the information delivered must be signed with the correspondent private key, so the receiver of the information will know it's not just some spammer inventing stuff, but actually the person who originated that record.

2024-01-14 13:55:28Things a coalition of evil miners can do on Bitcoin
If a miner coalition has 75% of hashrate for 6 months they can steal coins from a Drivechain without any risk, that's what the drivechain haters say.
What other evil things can a coalition of 75% hashrate do in 6 months?
- steal money from all open Lightning nodes on the network by opening channels to them, mining 3 blocks, spending the funds out on Lightning instantly, then rolling back the 3 blocks and canceling the channel.
- the above would eventually -- but not instantly and only after many steals have happened (even if they're not all perfectly coordinated and instant) -- cause Lightning to shrink in size a lot and become more of a closed friends network than truly open.
- only mine empty blocks and cause the mempool to be enormously clogged.
- refuse to use the mempool, force a proprietary API for transaction propagation with zero transparency and force other miners to use that same infrastructure too and extract a fee from them.
- censor anything and force other miners to censor too, at the threat of orphaning their blocks.
- easily cause so much confusion in the mining process that Bitcoin is deemed unusable and price falls drastically, miners can then buy at low price.

2025-05-08 05:25:48Safe Bits & Self Custody Tips
The journey of onboarding a user and create a bitcoin multiSig setup begins far before opening a desktop like Bitcoin Safe (BS) or any other similar application. Bitcoin Safe seems designed for families and people that want to start exploring and learning about multiSig setup. The need for such application and use of it could go much further, defining best practices for private organizations that aim to custody bitcoin in a private and anonymous way, following and enjoy the values and standards bitcoin has been built for.
Intro
Organizations and small private groups like families, family offices and solopreneurs operating on a bitcoin standard will have the need to keep track of transactions and categorize them to keep the books in order. A part of our efforts will be spent ensuring accessibility standards are in place for everyone to use Bitcoin Safe with comfort and safety.
We aim with this project to bring together the three Designathon ideas below: - Bitcoin Safe: improve its overall design and usability. - No User Left Behind: improve Bitcoin Safe accessibility. - Self-custody guidelines for organizations: How Bitcoin Safe can be used by private organization following best self-custody practices.
We are already halfway of the first week, and here below the progress made so far.
Designing an icon Set for Bitcoin Safe
One of the noticeable things when using BS is the inconsistency of the icons, not just in colors and shapes, but also the way are used. The desktop app try to have a clean design that incorporate with all OS (Win, macOS, Linux) and for this reason it's hard to define when a system default icon need to be used or if a custom one can be applied instead. The use of QT Ui framework for python apps help to respond to these questions. It also incorporates and brig up dome default settings that aren't easily overwritten.
Here below you can see the current version of BS:
Defining a more strict color palette for Bitcoin Safe was the first thing!
How much the icons affect accessibility? How they can help users to reach the right functionality? I took the challenge and, with PenPot.app, redesigned the icons based on the grid defined in the https://bitcoinicons.com/ and proposing the implementation of it to have a cleaner and more consistent look'n feel, at least for the icons now.
What's next
I personally look forward to seeing these icons implemented soon in Bitcoin Safe interface. In the meantime, we'll focus on delivering an accessibility audit and evaluate options to see how BS could be used by private organizations aiming to become financially sovereign with self-custody or more complex bitcoin multiSig setups.
One of the greatest innovations BS is bringing to us is the ability to sync the multiSig wallets, including PBST, Categories and labels, through the nostr decentralized protocol, making current key custodial services somehow obsolete. Second-coolest feature that this nostr implementation brings is the ability to have a build-in private chat that connect and enable the various signers of a multiSig to communicate and sign transactions remotely. Where have you seen something like this before?
Categories UX and redesign is also considered in this project. We'll try to understand how to better serve this functionality to you, the user, really soon.
Stay tuned!

2025-02-25 15:20:39If you don't know where your posts are, you might as well just stay in the centralized Twitter. You either take control of your relay lists, or they will control you. Amethyst offers several lists of relays for our users. We are going to go one by one to help clarify what they are and which options are best for each one.
Public Home/Outbox Relays
Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates.
Home relays must allow queries from anyone, ideally without the need to authenticate. They can limit writes to paid users without affecting anyone's experience.
This list should have a maximum of 3 relays. More than that will only make your followers waste their mobile data getting your posts. Keep it simple. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of all your content in a place no one can delete. Go to relay.tools and never be censored again. - 1 really fast relay located in your country: paid options like http://nostr.wine are great
Do not include relays that block users from seeing posts in this list. If you do, no one will see your posts.
Public Inbox Relays
This relay type receives all replies, comments, likes, and zaps to your posts. If you are not getting notifications or you don't see replies from your friends, it is likely because you don't have the right setup here. If you are getting too much spam in your replies, it's probably because your inbox relays are not protecting you enough. Paid relays can filter inbox spam out.
Inbox relays must allow anyone to write into them. It's the opposite of the outbox relay. They can limit who can download the posts to their paid subscribers without affecting anyone's experience.
This list should have a maximum of 3 relays as well. Again, keep it small. More than that will just make you spend more of your data plan downloading the same notifications from all these different servers. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of your notifications, invites, cashu tokens and zaps. - 1 really fast relay located in your country: go to nostr.watch and find relays in your country
Terrible options include: - nostr.wine should not be here. - filter.nostr.wine should not be here. - inbox.nostr.wine should not be here.
DM Inbox Relays
These are the relays used to receive DMs and private content. Others will use these relays to send DMs to you. If you don't have it setup, you will miss DMs. DM Inbox relays should accept any message from anyone, but only allow you to download them.
Generally speaking, you only need 3 for reliability. One of them should be a personal relay to make sure you have a copy of all your messages. The others can be open if you want push notifications or closed if you want full privacy.
Good options are: - inbox.nostr.wine and auth.nostr1.com: anyone can send messages and only you can download. Not even our push notification server has access to them to notify you. - a personal relay to make sure no one can censor you. Advanced settings on personal relays can also store your DMs privately. Talk to your relay operator for more details. - a public relay if you want DM notifications from our servers.
Make sure to add at least one public relay if you want to see DM notifications.
Private Home Relays
Private Relays are for things no one should see, like your drafts, lists, app settings, bookmarks etc. Ideally, these relays are either local or require authentication before posting AND downloading each user\'s content. There are no dedicated relays for this category yet, so I would use a local relay like Citrine on Android and a personal relay on relay.tools.
Keep in mind that if you choose a local relay only, a client on the desktop might not be able to see the drafts from clients on mobile and vice versa.
Search relays:
This is the list of relays to use on Amethyst's search and user tagging with @. Tagging and searching will not work if there is nothing here.. This option requires NIP-50 compliance from each relay. Hit the Default button to use all available options on existence today: - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays:
This is your local storage. Everything will load faster if it comes from this relay. You should install Citrine on Android and write ws://localhost:4869 in this option.
General Relays:
This section contains the default relays used to download content from your follows. Notice how you can activate and deactivate the Home, Messages (old-style DMs), Chat (public chats), and Global options in each.
Keep 5-6 large relays on this list and activate them for as many categories (Home, Messages (old-style DMs), Chat, and Global) as possible.
Amethyst will provide additional recommendations to this list from your follows with information on which of your follows might need the additional relay in your list. Add them if you feel like you are missing their posts or if it is just taking too long to load them.
My setup
Here's what I use: 1. Go to relay.tools and create a relay for yourself. 2. Go to nostr.wine and pay for their subscription. 3. Go to inbox.nostr.wine and pay for their subscription. 4. Go to nostr.watch and find a good relay in your country. 5. Download Citrine to your phone.
Then, on your relay lists, put:
Public Home/Outbox Relays: - nostr.wine - nos.lol or an in-country relay. -
.nostr1.com Public Inbox Relays - nos.lol or an in-country relay -
.nostr1.com DM Inbox Relays - inbox.nostr.wine -
.nostr1.com Private Home Relays - ws://localhost:4869 (Citrine) -
.nostr1.com (if you want) Search Relays - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays - ws://localhost:4869 (Citrine)
General Relays - nos.lol - relay.damus.io - relay.primal.net - nostr.mom
And a few of the recommended relays from Amethyst.
Final Considerations
Remember, relays can see what your Nostr client is requesting and downloading at all times. They can track what you see and see what you like. They can sell that information to the highest bidder, they can delete your content or content that a sponsor asked them to delete (like a negative review for instance) and they can censor you in any way they see fit. Before using any random free relay out there, make sure you trust its operator and you know its terms of service and privacy policies.

2025-02-18 20:30:32For the last couple of weeks, I've been dealing with the fallout of upgrading a web application to Svelte 5. Complaints about framework churn and migration annoyances aside, I've run into some interesting issues with the migration. So far, I haven't seen many other people register the same issues, so I thought it might be constructive for me to articulate them myself.
I'll try not to complain too much in this post, since I'm grateful for the many years of Svelte 3/4 I've enjoyed. But I don't think I'll be choosing Svelte for any new projects going forward. I hope my reflections here will be useful to others as well.
If you're interested in reproductions for the issues I mention here, you can find them below.
The Need for Speed
To start with, let me just quickly acknowledge what the Svelte team is trying to do. It seems like most of the substantial changes in version 5 are built around "deep reactivity", which allows for more granular reactivity, leading to better performance. Performance is good, and the Svelte team has always excelled at reconciling performance with DX.
In previous versions of Svelte, the main way this was achieved was with the Svelte compiler. There were many ancillary techniques involved in improving performance, but having a framework compile step gave the Svelte team a lot of leeway for rearranging things under the hood without making developers learn new concepts. This is what made Svelte so original in the beginning.
At the same time, it resulted in an even more opaque framework than usual, making it harder for developers to debug more complex issues. To make matters worse, the compiler had bugs, resulting in errors which could only be fixed by blindly refactoring the problem component. This happened to me personally at least half a dozen times, and is what ultimately pushed me to migrate to Svelte 5.
Nevertheless, I always felt it was an acceptable trade-off for speed and productivity. Sure, sometimes I had to delete my project and port it to a fresh repository every so often, but the framework was truly a pleasure to use.
Svelte is not Javascript
Svelte 5 doubled down on this tradeoff — which makes sense, because it's what sets the framework apart. The difference this time is that the abstraction/performance tradeoff did not stay in compiler land, but intruded into runtime in two important ways:
- The use of proxies to support deep reactivity
- Implicit component lifecycle state
Both of these changes improved performance and made the API for developers look slicker. What's not to like? Unfortunately, both of these features are classic examples of a leaky abstraction, and ultimately make things more complex for developers, not less.
Proxies are not objects
The use of proxies seems to have allowed the Svelte team to squeeze a little more performance out of the framework, without asking developers to do any extra work. Threading state through multiple levels of components without provoking unnecessary re-renders in frameworks like React is an infamously difficult chore.
Svelte's compiler avoided some of the pitfalls associated with virtual DOM diffing solutions, but evidently there was still enough of a performance gain to be had to justify the introduction of proxies. The Svelte team also seems to argue that their introduction represents an improvement in developer experience:
we... can maximise both efficiency and ergonomics.
Here's the problem: Svelte 5 looks simpler, but actually introduces more abstractions.
Using proxies to monitor array methods (for example) is appealing because it allows developers to forget all the goofy heuristics involved with making sure state was reactive and just
push
to the array. I can't count how many times I've writtenvalue = value
to trigger reactivity in svelte 4.In Svelte 4, developers had to understand how the Svelte compiler worked. The compiler, being a leaky abstraction, forced its users to know that assignment was how you signaled reactivity. In svelte 5, developers can just "forget" about the compiler!
Except they can't. All the introduction of new abstractions really accomplishes is the introduction of more complex heuristics that developers have to keep in their heads in order to get the compiler to act the way they want it to.
In fact, this is why after years of using Svelte, I found myself using Svelte stores more and more often, and reactive declarations less. The reason being that Svelte stores are just javascript. Calling
update
on a store is simple, and being able to reference them with a$
was just a nice bonus — nothing to remember, and if I mess up the compiler yells at me.Proxies introduce a similar problem to reactive declarations, which is that they look like one thing but act like another on the edges.
When I started using Svelte 5, everything worked great — until I tried to save a proxy to indexeddb, at which point I got a
DataCloneError
. To make matters worse, it's impossible to reliably tell if something is aProxy
withouttry/catch
ing a structured clone, which is a performance-intensive operation.This forces the developer to remember what is and what isn't a Proxy, calling
$state.snapshot
every time they pass a proxy to a context that doesn't expect or know about them. This obviates all the nice abstractions they gave us in the first place.Components are not functions
The reason virtual DOM took off way back in 2013 was the ability to model your application as composed functions, each of which takes data and spits out HTML. Svelte retained this paradigm, using a compiler to sidestep the inefficiencies of virtual DOM and the complexities of lifecycle methods.
In Svelte 5, component lifecycles are back, react-hooks style.
In React, hooks are an abstraction that allows developers to avoid writing all the stateful code associated with component lifecycle methods. Modern React tutorials universally recommend using hooks instead, which rely on the framework invisibly synchronizing state with the render tree.
While this does result in cleaner code, it also requires developers to tread carefully to avoid breaking the assumptions surrounding hooks. Just try accessing state in a
setTimeout
and you'll see what I mean.Svelte 4 had a few gotchas like this — for example, async code that interacts with a component's DOM elements has to keep track of whether the component is unmounted. This is pretty similar to the kind of pattern you'd see in old React components that relied on lifecycle methods.
It seems to me that Svelte 5 has gone the React 16 route by adding implicit state related to component lifecycles in order to coordinate state changes and effects.
For example, here is an excerpt from the documentation for $effect:
You can place $effect anywhere, not just at the top level of a component, as long as it is called during component initialization (or while a parent effect is active). It is then tied to the lifecycle of the component (or parent effect) and will therefore destroy itself when the component unmounts (or the parent effect is destroyed).
That's very complex! In order to use
$effect
... effectively (sorry), developers have to understand how state changes are tracked. The documentation for component lifecycles claims:In Svelte 5, the component lifecycle consists of only two parts: Its creation and its destruction. Everything in-between — when certain state is updated — is not related to the component as a whole; only the parts that need to react to the state change are notified. This is because under the hood the smallest unit of change is actually not a component, it’s the (render) effects that the component sets up upon component initialization. Consequently, there’s no such thing as a “before update”/"after update” hook.
But then goes on to introduce the idea of
tick
in conjunction with$effect.pre
. This section explains that "tick
returns a promise that resolves once any pending state changes have been applied, or in the next microtask if there are none."I'm sure there's some mental model that justifies this, but I don't think the claim that a component's lifecycle is only comprised of mount/unmount is really helpful when an addendum about state changes has to come right afterward.
The place where this really bit me, and which is the motivation for this blog post, is when state gets coupled to a component's lifecycle, even when the state is passed to another function that doesn't know anything about svelte.
In my application, I manage modal dialogs by storing the component I want to render alongside its props in a store and rendering it in the
layout.svelte
of my application. This store is also synchronized with browser history so that the back button works to close them. Sometimes, it's useful to pass a callback to one of these modals, binding caller-specific functionality to the child component:javascript const {value} = $props() const callback = () => console.log(value) const openModal = () => pushModal(MyModal, {callback})
This is a fundamental pattern in javascript. Passing a callback is just one of those things you do.
Unfortunately, if the above code lives in a modal dialog itself, the caller component gets unmounted before the callback gets called. In Svelte 4, this worked fine, but in Svelte 5
value
gets updated toundefined
when the component gets unmounted. Here's a minimal reproduction.This is only one example, but it seems clear to me that any prop that is closed over by a callback function that lives longer than its component will be undefined when I want to use it — with no reassignment existing in lexical scope. It seems that the reason this happens is that the props "belong" to the parent component, and are accessed via getters so that the parent can revoke access when it unmounts.
I don't know why this is necessary, but I assume there's a good engineering reason for it. The problem is, this just isn't how javascript works. Svelte is essentially attempting to re-invent garbage collection around component lifecycles, which breaks the assumption every javascript developer has that variables don't simply disappear without an explicit reassignment. It should be safe to pass stuff around and let the garbage collector do its job.
Conclusion
Easy things are nice, but as Rich Hickey says, easy things are not always simple. And like Joel Spolsky, I don't like being surprised. Svelte has always been full of magic, but with the latest release I think the cognitive overhead of reciting incantations has finally outweighed the power it confers.
My point in this post is not to dunk on the Svelte team. I know lots of people like Svelte 5 (and react hooks). The point I'm trying to make is that there is a tradeoff between doing things on the user's behalf, and giving the user agency. Good software is built on understanding, not cleverness.
I also think this is an important lesson to remember as AI-assisted coding becomes increasingly popular. Don't choose tools that alienate you from your work. Choose tools that leverage the wisdom you've already accumulated, and which help you to cultivate a deeper understanding of the discipline.
Thank you to Rich Harris and team for many years of pleasant development. I hope that (if you read this) it's not so full of inaccuracies as to be unhelpful as user feedback.

2024-01-14 13:55:28Truthcoin as a spacechain
To be clear, the term "spacechain" here refers only to the general concept of blindly merge-mined (BMM) chains without a native money-token, not including the "spacecoins".
The basic idea is that for Truthcoin/Hivemind to work we need
- Balances of Votecoin tokens, i.e. a way to keep track of who owns how much of the oracle corporation;
- Bitcoin tokens to be used for buying and selling prediction market shares, i.e. money to gamble;
- A blockchain, i.e. some timestamping service that emits blocks ordered with transactions and can keep track of internal state and change the state -- including the balances of the Votecoin tokens and of the Bitcoin tokens that are assigned to individual prediction markets according to predefined rules;
A spacechain, i.e. a blindly merge-mined chain, gives us 1 and 3. We can just write any logic for that and that should be very easy. It doesn't give us 2, and it also has the problem of how the spacechain users can pay the spacechain miners (which is why the spacecoins were envisioned in the first place, but we don't have spacecoins here).
But remember we have votecoins already. Votecoins (VTC) should represent a share in the oracle corporation, which means they entitle their holders to some revenue -- even though they also burden their holders with the duty to vote in event outcomes (at the risk of losing part of their own votecoin balance) --, and they can be exchanged, so we can assume they will have some value.
So we could in theory use these valuable tokens to pay the spacechain miners. That wouldn't be great because it pervert their original purpose and wouldn't solve the problem 2 from above -- unless we also used the votecoins to bet in which case they wouldn't be just another shitcoin in the planet with no network effect competing against Bitcoin and would just cause harm to humanity.
What we can do instead is to create a native mechanism for issuing virtual Bitcoin tokens (vBTC) in this chain, collaterized by votecoins, then we can use these vBTC to both gamble (solve problem 2) and pay miners (fix the hole in the spacechain BMM design).
For example, considering the VTC to be worth 0.001 BTC, any VTC holder could put 0.005 VTC and get 0.001 vBTC, then use to gamble or sell to others who want to gamble. The VTC holder still technically owns the VTC and can and must still participate in the oracle decisions. They just have to pay the BTC back before they can claim their VTC back if they want to send it elsewhere.
They stand to gain by selling vBTC if there is a premium for vBTC over BTC (i.e. people want to gamble) and then rebuying vBTC back once that premium goes away or reverts itself.
For this scheme to work the chain must know the exchange rate between VTC and BTC, which can be provided by the oracle corporation itself.

2025-05-11 22:53:30As I'm sitting here trying to hone in on what might be important to write about in this moment, my mind keeps swirling around through all the things that have me sitting here to begin with. Nostr found me in a time when my life needed a change. The discovery of something that provided the light of hope to an otherwise dark, dystopian future was more powerful than I could have ever predicted. Timing is everything, they say. I believe that to be half true, as timing alone means nothing if the will is non-existent. The intersection of opportunity and preparedness, and all that. I know how I found my way here, but I do not fully understand the things that have drawn my curiosity and kept my attention so strongly. My will ached for change, simplicity, and meaning. I found it, in what seem to me, simultaneously the most likely and the most unlikely of places. There's a magic to that, and its probably better to leave some questions unanswered, lest they lose their mystic power.
My experiences are my own but theme of them resonates through most of the people with whom I interact. It's been very clear that I wasn't alone in these feelings. A movement of highly inspired, hopeful people have continued to support this digital freedom movement since my arrival, in varying ways. Some people have highly technical skills ranging from network systems to design to cybersecurity. Others, like myself, have little to offer in the realms of functionality and we do what we can to breathe life into the systems built to provide digital freedom of speech for all. It's a humbling experience. We are reminded. sometimes directly and sometimes indirectly, that none of Nostr would matter if there were no one using it. We know this to be true, but it is no less humbling to be surrounded by constant innovation and a thriving desire to bring this experience to the entire world.
Now here I sit, tapping out these words, in the midst of another massive life change, stressful but chosen. I could sign off, go read a book in the garden, and go about my world as I would have in my pre-Nostr times. I don't want to do that, though. Hope is here. If there is a place to dwell, in hope is where I will always choose.
I find it important to acknowledge, though, that Nostr and the people using it are in a constant state of flux, too. This isn't my rock nor harbor nor shelter. It's the chaotic good, reminding me both to keep an appreciation for how far this ecosystem has come in such a short amount of time and a realistic set of expectations for where this all can go. The same applies for how well things work at any given moment...And equally so in missing my some of my early Nostr friends that have come and gone, while remaining open to the possibility of meeting new ones... Experiences had and experiences yet to come. I don't know if I have ever been so coaxed outside of my mind by a group of strangers on the internet. But here I am, looking back and looking forward, surrounded by awe in all directions, sharing thoughts that would otherwise be scribbled in pen to be burned in a random evening fire. I've long felt that the core of social media should be just this. Spaces for people to connect, above all else, in the ways that create meaning in our lives. I suppose in some ways that did exist before, but it was twisted, and obscured, and slowly pulled away.
Now its here and super-charged by possibility. What this looks like for any individual will not be the same as my own view. That's part of what makes this so beautiful to me. We need to be able to speak freely. Just as importantly we need to be able to surround ourselves with the things and people that makes us want to do more, that make us want to feel humbled. Or not, if we so choose... but I choose hope.

2024-01-14 13:55:28A Causa
o Princípios de Economia Política de Menger é o único livro que enfatiza a CAUSA o tempo todo. os cientistas todos parecem não saber, ou se esquecer sempre, que as coisas têm causa, e que o conhecimento verdadeiro é o conhecimento da causa das coisas.
a causa é uma categoria metafísica muito superior a qualquer correlação ou resultado de teste de hipótese, ela não pode ser descoberta por nenhum artifício econométrico ou reduzida à simples antecedência temporal estatística. a causa dos fenômenos não pode ser provada cientificamente, mas pode ser conhecida.
o livro de Menger conta para o leitor as causas de vários fenômenos econômicos e as interliga de forma que o mundo caótico da economia parece adquirir uma ordem no momento em que você lê. é uma sensação mágica e indescritível.
quando eu te o recomendei, queria é te imbuir com o espírito da busca pela causa das coisas. depois de ler aquilo, você está apto a perceber continuidade causal nos fenômenos mais complexos da economia atual, enxergar as causas entre toda a ação governamental e as suas várias consequências na vida humana. eu faço isso todos os dias e é a melhor sensação do mundo quando o caos das notícias do caderno de Economia do jornal -- que para o próprio jornalista que as escreveu não têm nenhum sentido (tanto é que ele escreve tudo errado) -- se incluem num sistema ordenado de causas e consequências.
provavelmente eu sempre erro em alguns ou vários pontos, mas ainda assim é maravilhoso. ou então é mais maravilhoso ainda quando eu descubro o erro e reinsiro o acerto naquela racionalização bela da ordem do mundo econômico que é a ordem de Deus.

2025-05-11 22:33:46Originalni tekst na dvadesetjedan.com
Autor: Vijay Boyapati / Prevod na hrvatski: Matija
Sa zadnjim cijenama koje je bitcoin dosegao 2017., optimističan scenarij za ulagače se možda čini toliko očitim da ga nije potrebno niti spominjati. Alternativno, možda se nekome čini glupo ulagati u digitalnu vrijednost koja ne počiva na nijednom fizičkom dobru ili vladi i čiji porast cijene su neki usporedili sa manijom tulipana ili dot-com balonom. Nijedno nije točno; optimističan scenarij za Bitcoin je uvjerljiv, ali ne i očit. Postoje značajni rizici kod ulaganja u Bitcoin, no, kao što planiram pokazati, postoji i ogromna prilika.
Geneza
Nikad u povijesti svijeta nije bilo moguće napraviti transfer vrijednosti među fizički udaljenim ljudima bez posrednika, poput banke ili vlade. 2008. godine, anonimni Satoshi Nakamoto je objavio 8 stranica rješenja na dugo nerješivi računalski problem poznat kao “Problem Bizantskog Generala.” Njegovo rješenje i sustav koji je izgradio - Bitcoin - dozvolio je, prvi put ikad, da se vrijednost prenosi brzo i daleko, bez ikakvih posrednika ili povjerenja. Implikacije kreacije Bitcoina su toliko duboke, ekonomski i računalski, da bi Nakamoto trebao biti prva osoba nominirana za Nobelovu nagradu za ekonomiju i Turingovu nagradu.
Za ulagače, važna činjenica izuma Bitcoina (mreže i protokola) je stvaranje novog oskudnog digitalnog dobra - bitcoina (monetarne jedinice). Bitcoini su prenosivi digitalni “novčići” (tokeni), proizvedeni na Bitcoin mreži kroz proces nazvan “rudarenje” (mining). Rudarenje Bitcoina je ugrubo usporedivo sa rudarenjem zlata, uz bitnu razliku da proizvodnja bitcoina prati unaprijed osmišljeni i predvidivi raspored. Samo 21 milijun bitcoina će ikad postojati, i većina (2017., kada je ovaj tekst napisan) su već izrudareni. Svake četiri godine, količina rudarenih bitcoina se prepolovi. Produkcija novih bitcoina će potpuno prestati 2140. godine.
Stopa inflacije —— Monetarna baza
Bitcoine ne podržava nikakva roba ili dobra, niti ih garantira ikakva vlada ili firma, što postavlja očito pitanje za svakog novog bitcoin ulagača: zašto imaju uopće ikakvu vrijednost? Za razliku od dionica, obveznica, nekretnina ili robe poput nafte i žita, bitcoine nije moguće vrednovati koristeći standardne ekonomske analize ili korisnost u proizvodnji drugih dobara. Bitcoini pripadaju sasvim drugoj kategoriji dobara - monetarnih dobara, čija se vrijednost definira kroz tzv. teoriju igara; svaki sudionik na tržištu vrednuje neko dobro, onoliko koliko procjenjuje da će ga drugi sudionici vrednovati. Kako bismo bolje razumjeli ovo svojstvo monetarnih dobara, trebamo istražiti podrijetlo novca.
Podrijetlo novca
U prvim ljudskim društvima, trgovina među grupama se vršila kroz robnu razmjenu. Velika neefikasnost prisutna u robnoj razmjeni je drastično ograničavala količinu i geografski prostor na kojem je bila moguća. Jedan od najvećih problema sa robnom razmjenom je problem dvostruke podudarnosti potražnje. Uzgajivač jabuka možda želi trgovati sa ribarom, ali ako ribar ne želi jabuke u istom trenutku, razmjena se neće dogoditi. Kroz vrijeme, ljudi su razvili želju za čuvanjem određenih predmeta zbog njihove rijetkosti i simbolične vrijednosti (npr. školjke, životinjski zube, kremen). Zaista, kako i Nick Szabo govori u svojem izvrsnom eseju o podrijetlu novca, ljudska želja za sakupljanjem predmeta pružila je izraženu evolucijsku prednost ranom čovjeku nad njegovim najbližim biološkim rivalom, neandertalcem - Homo neanderthalensis.
"Primarna i najbitnija evolucijska funkcija sakupljanja bila je osigurati medij za čuvanje i prenošenje vrijednosti".
Predmeti koje su ljudi sakupljali služili su kao svojevrsni “proto-novac,” tako što su omogućavale trgovinu među antagonističkim plemenima i dozvoljavale bogatsvu da se prenosi na sljedeću generaciju. Trgovina i transfer takvih predmeta bile su rijetke u paleolitskim društvima, te su oni služili više kao “spremište vrijednosti” (store of value) nego kao “medij razmjene” (medium of exchange), što je uloga koju danas igra moderni novac. Szabo objašnjava:
"U usporedbi sa modernim novcem, primitivan novac je imao jako malo “brzinu” - mogao je promijeniti ruke samo nekoliko puta u životu prosječnog čovjeka. Svejedno, trajni i čvrsti sakupljački predmet, što bismo danas nazvali “nasljeđe,” mogao je opstati mnogo generacija, dodajući znatnu vrijednost pri svakom transferu - i zapravo omogućiti transfer uopće".
Rani čovjek suočio se sa bitnom dilemom u teoriji igara, kada je odlučivao koje predmete sakupljati: koje od njih će drugi ljudi željeti? Onaj koji bi to točno predvidio imao bi ogromnu prednost u mogućnosti trgovine i akvizicije bogatsva. Neka američka indijanska plemena, npr. Naraganseti, specijalizirala su se u proizvodnji sakupljačkih dobara koja nisu imala drugu svrhu osim trgovine. Valja spomenuti da što je ranije predviđanje da će neko dobro imati takvu vrijednost, veća je prednost koju će imati onaj koji je posjeduje, zato što ju je moguće nabaviti jeftinije, prije nego postane vrlo tražena roba i njezona vrijednost naraste zajedno sa populacijom. Nadalje, nabava nekog dobra u nadi da će u budućnosti biti korišteno kao spremište vrijednosti, ubrzava upravo tu primjenu. Ova cirkularnost je zapravo povratna veza (feedback loop) koja potiče društva da se rapidno slože oko jednog spremišta vrijednosti. U terminima teorije igara, ovo je znano kao “Nashov ekvilibrij.” Postizanje Nashovog ekvilibrija za neko spremište vrijednosti je veliko postignuće za društvo, pošto ono znatno olakšava trgovinu i podjelu rada, i time omogućava napredak civilizacije.
Tisućljećima, kako su ljudska društva rasla i otvarala trgovinske puteve, različite aplikacije spremišta vrijednosti u individualnim društvima počele su se natjecati međusobno. Trgovci su imali izbor: čuvati svoju zaradu u spremištu vrijednosti vlastite kulture, ili one kulture sa kojom su trgovali, ili mješavini oboje. Benefit štednje u stranom spremištu vrijednosti bila je uvećana sposobnost trgovanja u povezanom stranom društvu. Trgovci koji su štedili u stranom spremištu vrijednosti su također imali dobrih razloga da potiču svoje društvo da ga prihvati, jer bi tako uvećali vrijednost vlastite ušteđevine. Prednosti “uvezene” tehnologije spremanja vrijednosti bile su prisutne ne samo za trgovce, nego i za sama društva. Kada bi se dvije grupe konvergirale u jedinstvenom spremištu vrijednosti, to bi značajno smanjilo cijenu troškova trgovine jednog s drugim, i samim time povećanje bogatstva kroz trgovinu. I zaista, 19. stoljeće bilo je prvi put da je najveći dio svijeta prihvatio jedinstveno spremište vrijednosti - zlato - i u tom periodu vidio najveću eksploziju trgovine u povijesti svijeta. O ovom mirnom periodu, pisao je John Maynard Keynes:
"Kakva nevjerojatna epizoda u ekonomskom napretku čovjeka… za svakog čovjeka iole iznadprosječnog, iz srednje ili više klase, život je nudio obilje, ugodu i mogućnosti, po niskoj cijeni i bez puno problema, više nego monarsima iz prethodnih perioda. Stanovnik Londona mogao je, ispijajući jutarnji čaj iz kreveta, telefonski naručiti razne proizvode iz cijele Zemlje, u količinama koje je želio, i sa dobrim razlogom očekivati njihovu dostavu na svoj kućni prag."
Svojstva dobrog spremišta vrijednosti
Kada se spremišta vrijednosti natječu jedno s drugim, specifična svojstva rade razliku koja daje jednom prednost nad drugim. Premda su mnoga dobra u prošlosti korištena kao spremišta vrijednosti ili kao “proto-novac,” određena svojstva su se pokazala kao posebno važna, i omogućila dobrima sa njima da pobijede. Idealno spremište vrijednosti biti će:
- Trajno: dobro ne smije biti kvarljivo ili lako uništeno. Tako naprimjer, žito nije idealno spremište vrijednosti.
- Prenosivo: dobro mora biti lako transportirati i čuvati, što omogućuje osiguranje protiv gubitka ili krađe i dopušta trgovinu na velike udaljenosti. Tako, krava je lošije spremište vrijednosti od zlatne narukvice.
- Zamjenjivo: jedna jedinica dobra treba biti zamjenjiva sa drugom. Bez zamjenjivosti, problem podudarnosti želja ostaje nerješiv. Time, zlato je bolje od dijamanata, jer su oni nepravilni u obliku i kvaliteti.
- Provjerljivo: dobro mora biti lako i brzo identificirano i testirano za autentičnost. Laka provjera povećava povjerenje u trgovini i vjerojatnost da će razmjena biti dovršena.
- Djeljivo: dobro mora biti lako djeljivo na manje dijelove. Premda je ovo svojstvo bilo manje važno u ranim društvima gdje je trgovina bila rijetka, postalo je važnije sa procvatom trgovine. Količine koje su se mijenjale postale su manje i preciznije.
- Oskudno: Monetarno dobro mora imati “cijenu nemoguću za lažirati,” kao što je rekao Nick Szabo. Drugim riječima, dobro ne smije biti obilno ili lako dostupno kroz proizvodnju. Oskudnost je možda i najvažnije svojstvo spremišta vrijednosti, pošto se izravno vezuje na ljudsku želju da sakupljamo ono što je rijetko. Ona je izvor vrijednosti u spremištu vrijednosti.
- Duge povijesti: što je dulje neko dobro vrijedno za društvo, veća je vjerojatnost da će biti prihvaćeno kao spremište vrijednosti. Dugo postojeće spremište vrijednosti biti će jako teško uklonjeno od strane došljaka, osim u slučaju sile (ratno osvajanje) ili ako je nova tehnologija znatno bolja u ostalim svojstvima.
- Otporno na cenzuru: novije svojstvo, sve više važno u modernom digitalnom svijetu sa sveprisutnim nadzorom, je otpornost na cenzuru. Drugim riječima, koliko je teško da vanjski agent, kao korporacija ili država, spriječi vlasnika dobra da ga čuva i koristi. Dobra koja su otporna na cenzuru su idealna za ljude koji žive u režimima koji prisilno nadziru kapital ili čine neke oblike mirne trgovine protuzakonitima.
Ova tablica ocjenjuje Bitcoin, zlato (gold) i fiat novac (kao što je euro ili dolar) po svojstvima izlistanim gore. Objašnjenje svake ocjene slijedi nakon tablice.
Trajnost:
Zlato je neosporeni kralj trajnosti. Velika većina zlata pronađenog kroz povijest, uključujući ono egipatskih faraona, opstaje i danas i vjerojatno će postojati i za tisuću godina. Zlatnici korišteni u antičko doba imaju značajnu vrijednost i danas. Fiat valute i bitcoini su digitalni zapisi koji ponekad imaju fizički oblik (npr. novčanice). Dakle, njihovu trajnost ne određuju njihova fizička svojstva (moguće je zamijeniti staru i oštećenu novčanicu za novu), nego institucije koje stoje iza njih. U slučaju fiat valuta, mnoge države su nastale i nestale kroz stoljeća, i valute su nestale s njima. Marke iz Weimarske republike danas nemaju vrijednost zato što institucija koja ih je izdavala više ne postoji. Ako je povijest ikakav pokazatelj, ne bi bilo mudro smatrati fiat valute trajnima dugoročno; američki dolar i britanska funta su relativne anomalije u ovom pogledu. Bitcoini, zato što nemaju instituciju koja ih održava, mogu se smatrati trajnima dok god mreža koja ih osigurava postoji. Obzirom da je Bitcoin još uvijek mlada valuta, prerano je za čvrste zaključke o njegovoj trajnosti. No, postoje ohrabrujući znakovi - prominente države su ga pokušavale regulirati, hakeri ga napadali - usprkos tome, mreža nastavlja funkcionirati, pokazujući visok stupanj antifragilnosti.
Prenosivost:
Bitcoini su najprenosivije spremište vrijednosti ikad. Privatni ključevi koji predstavljaju stotine milijuna dolara mogu se spremiti na USB drive i lako ponijeti bilo gdje. Nadalje, jednako velike sume mogu se poslati na drugi kraj svijeta skoro instantno. Fiat valute, zbog svojeg temeljno digitalnog oblika, su također lako prenosive. Ali, regulacije i kontrola kapitala od strane države mogu ugroziti velike prijenose vrijednosti, ili ih usporiti danima. Gotovina se može koristiti kako bi se izbjegle kontrole kapitala, ali onda rastu rizik čuvanja i cijena transporta. Zlato, zbog svojeg fizičkog oblika i velike gustoće, je najmanje prenosivo. Nije čudo da većina zlatnika i poluga nikad ne napuste sefove. Kada se radi prijenos zlata između prodavača i kupca, uglavnom se prenosi samo ugovor o vlasništvu, ne samo fizičko zlato. Prijenos fizičkog zlata na velike udaljenosti je skupo, riskantno i sporo.
Zamjenjivost:
Zlato nam daje standard za zamjenjivost. Kada je rastopljeno, gram zlata je praktički nemoguće razlikovati od bilo kojeg drugog grama, i zlato je oduvijek bilo takvo. S druge strane, fiat valute, su zamjenjive samo onoliko koliko njihova institucija želi da budu. Iako je uglavnom slučaj da je novčanica zamjenjiva za drugu istog iznosa, postoje situacije u kojima su velike novčanice tretirane drukčije od malih. Naprimjer, vlada Indije je, u pokušaju da uništi neoporezivo sivo tržište, potpuno oduzela vrijednost novčanicama od 500 i 1000 rupija. To je uzrokovalo da ljudi manje vrednuju te novčanice u trgovini, što je značilo da više nisu bile zaista zamjenjive za manje novčanice. Bitcoini su zamjenjivi na razini mreže; svaki bitcoin je pri prijenosu tretiran kao svaki drugi. No, zato što je moguće pratiti individualne bitcoine na blockchainu, određeni bitcoin može, u teoriji, postati “prljav” zbog korštenja u ilegalnoj trgovini, te ga trgovci ili mjenjačnice možda neće htjeti prihvatiti. Bez dodatnih poboljšanja oko privatnosti i anonimnosti na razini mrežnog protokola, bitcoine ne možemo smatrati jednako zamjenjivim kao zlato.
Mogućnost provjere:
Praktično gledajući, autentičnost fiat valuta i zlata je prilično lako provjeriti. Svejedno, i usprkos pokušajima da spriječe krivotvorenje novčanica, i dalje postoji potencijal prevare za vlade i njihove građane. Zlato također nije imuno na krivotvorenje. Sofisticirani kriminalci su koristili pozlaćeni tungsten kako bi prevarili kupce zlata. Bitcoine je moguće provjeriti sa matematičkom sigurnošću. Korištenjem kriptografskih potpisa, vlasnik bitcoina može javno demonstrirati da posjeduje bitcoine koje tvrdi da posjeduje.
Djeljivost:
Bitcoine je moguće podijeliti u stotinu milijuna manjih jedinica (zvanih satoshi), i prenositi takve (no, valja uzeti u obzir ekonomičnost prijenosa malih iznosa, zbog cijene osiguravanja mreže - “network fee”). Fiat valute su tipično dovoljno djeljive na jedinice sa vrlo niskom kupovnom moći. Zlato, iako fizički i teoretski djeljivo, postaje teško za korištenje kada se podijeli na dovoljno male količine da bi se moglo koristiti u svakodnevnoj trgovini.
Oskudnost:
Svojstvo koje najjasnije razlikuje Bitcoin od fiat valuta i zlata je njegova unaprijed definirana oskudnost. Od početka, konačna količina bitcoina nikad neće biti veća od 21 milijun. To daje vlasnicima bitcoina jasan i znan uvid u postotak ukupnog vlasništva. Naprimjer, vlasnik 10 bitcoina bi znao da najviše 2,1 milijuna ljudi (manje od 0.03% populacije) može ikad imati isto bitcoina kao i on. Premda je kroz povijest uvijek bilo oskudno, zlato nije imuno na povećanje ukupne količine. Ako se ikad izumi nova, ekonomičnija metoda rudarenja ili proizvodnje zlata, ukupna količina zlata bi se mogla dramatično povećati (npr. rudarenje morskog dna ili asteroida). Na kraju, fiat valute, relativno nov izum u povijesti, pokazale su se sklonima konstantnim povećanjima u količini. Države su pokazale stalnu sklonost inflaciji monetarne kvantitete kako bi rješavale kratkoročne političke probleme. Inflacijske tendencije vlada diljem svijeta čine fiat valute gotovo sigurnim da će gubiti vrijednost kroz vrijeme.
Etablirana povijest:
Nijedno monetarno dobro nema povijest kao zlato, koje je imalo vrijednost za cijelog trajanja ljudske civilizacije. Kovanice izrađene u antičko doba i danas imaju značajnu vrijednost. Ne može se isto reći za fiat valute, koje su same relativno nova povijesna anomalija. Od njihovog početka, fiat valute su imale gotovo univerzalni smjer prema bezvrijednosti. Korištenje inflacije kao podmuklog načina za nevidljivo oporezivanje građana je vječita kušnja kojoj se skoro nijedna država u povijesti nije mogla oduprijeti. Ako je 20. stoljeće, u kojem je fiat novac dominirao globalni monetarni poredak, demonstriralo neku ekonomsku istinu, to je onda bila ta da ne možemo računati na fiat novac da održi vrijednost u dužem ili srednjem vremenskom periodu. Bitcoin, usprkos svojoj novosti, je preživio dovoljno testova tržišta da postoji velika vjerojatnost da neće nestati kao vrijedno dobro. Nadalje, Lindy efekt govori da što duže Bitcoin bude korišten, to će veća biti vjera u njega i njegovu sposobnost da nastavi postojati dugo u budućnost. Drugim riječima, društvena vjera u monetarno dobro je asimptotička, kao u grafu ispod:
Ako Bitcoin preživi prvih 20 godina, imat će gotovo sveopće povjerenje da će trajati zauvijek, kao što ljudi vjeruju da je internet trajna stvar u modernom svijetu.
Otpor na cenzuru
Jedan od najbitnijih izvora za ranu potražnju bitcoina bila je njegova upotreba u ilegalnoj kupovini i prodaji droge. Mnogi su zato pogrešno zaključili da je primarna potražnja za bitcoinima utemeljena u njihovoj prividnoj anonimnosti. Međutim, Bitcoin nije anonimna valuta; svaka transakcija na mreži je zauvijek zapisana na javnom blockchainu. Povijesni zapis transakcija dozvoljava forenzičkoj analizi da identificira izvore i tijek sredstava. Takva analiza dovela je do uhićenja počinitelja zloglasne MtGox pljačke. Premda je istina da dovoljno oprezna i pedantna osoba može sakriti svoj identitet koristeći Bitcoin, to nije razlog zašto je Bitcoin bio toliko popularan u trgovini drogom.
Ključno svojstvo koje čini Bitcoin najboljim za takve aktivnosti je njegova agnostičnost i nepotrebnost za dozvolom (“premissionlessness”) na mrežnoj razini. Kada se bitcoini prenose na Bitcoin mreži, ne postoji nitko tko dopušta transakcije. Bitcoin je distribuirana peer-to-peer (korisnik-korisniku) mreža, i samim time dizajnirana da bude otporna na cenzuru. Ovo je u velikom kontrastu sa fiat bankarskim sustavom, u kojem države reguliraju banke i ostale institucije prijenosa novca, kako bi one prijavljivale i sprječavale protuzakonito korištenje monetarnih dobara. Klasičan primjer regulacije novca su kontrole kapitala. Npr., bogati milijunaš će vrlo teško prenijeti svoje bogatstvo u novu zemlju, kada bježi iz opresivnog režima. Premda zlato nije izdano i proizvedeno od države, njegova fizička priroda ga čini teško prenosivim kroz prostor, i samim time ga je daleko lakše regulirati nego Bitcoin. Indijski Akt kontrole zlata je primjer takve regulacije.
Bitcoin je odličan u većini gore navedenih svojstava, što mu omogućava da bude marginalno bolji od modernih i drevnih monetarnih dobara, te da pruži poticaje za svoje rastuće društveno usvajanje. Specifično, moćna kombinacija otpornosti na cenzuru i apsolutne oskudnosti bila je velika motivacija za bogate ulagače koji su uložili dio svojeg bogatstva u Bitcoin.
Evolucija novca
U modernoj monetarnoj ekonomiji postoji opsesija sa ulogom novca kao medija razmjene. U 20. stoljeću, države su monopolizirale izdavanje i kontrolu novca i kontinuirano potkopavale njegovo svojstvo spremišta vrijednosti, stvarajući lažno uvjerenje da je primarna svrha novca biti medij razmjene. Mnogi su kritizirali Bitcoin, govoreći da je neprikladan da bude novac zato što mu je cijena bila previše volatilna za medij razmjene. No, novac je uvijek evoluirao kroz etape; uloga spremišta vrijednosti je dolazila prije medija razmjene. Jedan od očeva marginalističke ekonomije, William Stanley Jevons, objašnjava:
"Povijesno govoreći… čini se da je zlato prvo služilo kao luksuzni metal za ukras; drugo, kao sačuvana vrijednost; treće, kao medij razmjene; i konačno, kao mjerilo vrijednosti."
U modernoj terminologiji, novac uvijek evoluira kroz četiri stadija:
- Kolekcionarstvo: U prvoj fazi svoje evolucije, novac je tražen samo zbog svojih posebnih svojstava, uglavnom zbog želja onog koji ga posjeduje. Školjke, perlice i zlato su bili sakupljani prije nego su poprimili poznatije uloge novca.
- Spremište vrijednosti: Jednom kada je novac tražen od dovoljnog broja ljudi, biti će prepoznat kao način za čuvanje i spremanje vrijednosti kroz vrijeme. Kada neko dobro postane široko korišteno kao spremište vrijednosti, njegova kupovna moć raste sa povećanom potražnjom za tu svrhu. Kupovna moć spremišta vrijednosti će u jednom trenutku doći do vrhunca, kada je dovolno rašireno i broj novih ljudi koji ga potražuju splasne.
- Sredstvo razmjene: Kada je novac potpuno etabliran kao spremište vrijednosti, njegova kupovna moć se stabilizira. Nakon toga, postane prikladno sredstvo razmjene zbog stabilnosti svoje cijene. U najranijim danima Bitcoina, mnogi ljudi nisu shvaćali koju buduću cijenu plaćaju koristeći bitcoine kao sredstvo razmjene, umjesto kao novonastalo spremište vrijednosti. Poznata priča o čovjeku koji je za 10,000 bitcoina (vrijednih oko 94 milijuna dolara kada je ovaj članak napisan) za dvije pizze ilustrira ovaj problem.
- Jedinica računanja vrijednosti: Jednom kada je novac široko korišten kao sredstvo razmjene, dobra će biti vrednovana u njemu, tj. većina cijena će biti izražena u njemu. Uobičajena zabluda je da je većinu dobara moguće zamijeniti za bitcoine danas. Npr., premda je možda moguće kupiti šalicu kave za bitcoine, izlistana cijena nije prava bitcoin cijena; zapravo se radi o cijeni u državnoj valuti koju želi trgovac, preračunatu u bitcoin po trenutnoj tržišnoj cijeni. Kad bi cijena bitcoina pala u odnosu na valutu, vrijednost šalice izražena u bitcoinima bi se povećala. Od trenutka kada trgovci budu voljni prihvaćani bitcoine kao platežno sredstvo, bez obraćanja pažnje na vrijednost bitcoina u državnoj fiat valuti, moći ćemo reći da je Bitcoin zaista postao jedinica računanja vrijednosti.
Monetarna dobra koja još nisu jedinice računanja vrijednosti možemo smatrati “djelomično monetiziranima.” Danas zlato ima takvu ulogu, jer je spremište vrijednosti, ali su mu uloge sredstva razmjene i računanja vrijednosti oduzete intervencijama država. Moguće je također da se jedno dobro koristi kao sredstvo razmjene, dok druga ispunjavaju ostale uloge. To je tipično u zemljama gdje je država disfunkcionalna, npr. Argentina ili Zimbabwe. U svojoj knjizi, Digitalno zlato, Nathaniel Popper piše:
"U Americi, dolar služi trima funkcijama novca: nudi sredstvo razmjene, jedinicu za mjerenje vrijednosti dobara, i mjesto gdje se može čuvati vrijednosti. S druge strane, argentinski peso je korišten kao sredstvo razmjene (za svakodnevne potrebe), ali ga nitko nije koristio kao spremište vrijednosti. Štednja u pesosima bila je ekvivalent bacanja novca. Zato su ljudi svu svoju štednju imali u dolarima, jer je dolar bolje čuvao vrijednost. Zbog volatilnosti pesosa, ljudi su računali cijene u dolarima, što im je pružalo pouzdaniju jedinicu mjerenja kroz vrijeme."
Bitcoin je trenutno u fazi tranzicije iz prvog stadija monetizacije u drugi. Vjerojatno će proći nekoliko godina prije nego Bitcoin pređe iz začetaka spremišta vrijednosti u istinski medij razmjene, i put do tog trenutka je još uvijek pun rizika i nesigurnosti. Važno je napomenuti da je ista tranzicija trajala mnogo stoljeća za zlato. Nitko danas živ nije doživio monetizaciju dobra u realnom vremenu (kroz koju Bitcoin prolazi), tako da nemamo puno iskustva govoriti o putu i načinu na koji će se monetizacija dogoditi.
Put monetizacije
Kroz proces monetizacije, monetarno dobro će naglo porasti u kupovnoj moći. Mnogi su tako komentirali da je uvećanje kupovne moći Bitcoina izgledalo kao “balon” (bubble). Premda je ovaj termin često korišten kako bi ukazao na pretjeranu vrijednosti Bitcoina, sasvim slučajno je prikladan. Svojstvo koje je uobičajeno za sva monetarna dobra jest da je njihova kupovna moć viša nego što se može opravdati samo kroz njihovu uporabnu vrijednost. Zaista, mnogi povijesni novci nisu imali uporabnu vrijednost. Razliku između kupovne moći i vrijednosti razmjene koju bi novac mogao imati za svoju inherentnu korisnost, možemo razmatrati kao “monetarnu premiju.” Kako monetarno dobro prolazi kroz stadije monetizacije (navedene gore), monetarna premija raste. No, ta premija ne raste u ravnoj i predvidivoj liniji. Dobro X, koje je bilo u procesu monetizacije, može izgubiti u usporedbi sa dobrom Y koje ima više svojstava novca, te monetarna premija dobra X drastično padne ili potpuno nestane. Monetarna premija srebra je skoro potpuno nestala u kasnom 19. stoljeću, kada su ga vlade diljem svijeta zamijenile zlatom kao novcem.
Čak i u odsustvu vanjskih faktora, kao što su intervencije vlade ili druga monetarna dobra, monetarna premija novog novca neće ići predvidivim putem. Ekonomist Larry White primijetio je:
"problem sa pričom “balona,” naravno, je da je ona konzistentna sa svakim putem cijene, i time ne daje ikakvo objašnjenje za specifičan put cijene"
Proces monetizacije opisuje teorija igara; svaki akter na tržištu pokušava predvidjeti agregiranu potražnju ostalih aktera, i time buduću monetarnu premiju. Zato što je monetarna premija nevezana za inherentnu korisnost, tržišni akteri se uglavnom vode za prošlim cijenama da bi odredili je li neko dobro jeftino ili skupo, i žele li ga kupiti ili prodati. Veza trenutne potražnje sa prošlim cijenama naziva se “ovisnost o putu” (path dependence); ona je možda najveći izvor konfuzije u shvaćanju kretanja cijena monetarnih dobara.
Kada kupovna moć monetarnog dobra naraste zbog većeg i šireg korištenja, očekivanja tržišta o definicijama “jeftinog” i “skupog” se mijenjaju u skladu s time. Slično tome, kada cijena monetarnog dobra padne, očekivanja tržišta mogu se promijeniti u opće vjerovanje da su prethodne cijene bile “iracionalne” ili prenapuhane. Ovisnost o putu novca ilustrirana je riječima poznatog upravitelja fondova s Wall Streeta, Josha Browna:
"Kupio sam bitcoine kada su koštali $2300, i to mi se udvostručilo gotovo odmah. Onda sam počeo govoriti kako “ne mogu kupiti još” dok im je cijena rasla, premda sam znao da je to razmišljanje bazirano samo na cijenu po kojoj sam ih kupio. Kasnije, kada je cijena pala zbog kineske regulacije mjenjačnica, počeo sam si govoriti, “Odlično, nadam se da će još pasti da mogu kupiti još.”"
Istina leži u tome da su ideje “jeftinog” i “skupog” zapravo besmislene kada govorimo o monetarnim dobrima. Cijena monetarnog dobra ne reflektira njegovu stopu rasprostanjenosti ili korisnosti, nego mjeru koliko je ono široko prihvaćeno da ispuni razne uloge novca.
Dodatna komplikacija u ovom aspektu novca je činjenica da tržišni akteri ne djeluju samo kao nepristrani promatrači koji pokušavaju kupiti i prodati u iščekivanju budućih kretanja monetarne premije, nego i kao aktivni proponenti. Pošto ne postoji objektivno “točna” monetarna premija, širiti dobar glas o superiornijim svojstvima nekog monetarnog dobra je efektivnije nego za obična dobra, čija vrijednost je u konačnici vezana na njegovu osnovnu korisnost. Religiozni zanos sudionika na Bitcoin tržištu vidljiv je na raznim internetskim forumima, gdje Bitcoineri aktivno promoviraju benefine Bitcoina i bogatstvo koje je moguće ostvariti investiranjem u njega. Promatrajući Bitcoin tržište, Leigh Drogen komentira:
"To je prepoznatljivo svima kao religija - priča koju si pričamo i oko koje se slažemo. Religija je krivulja na grafu prihvaćanja o kojoj trebamo razmišljati. Sustav je gotovo savršen - onog trenutka kada netko pristupi krugu Bitcoinera, to će reći svima i nastaviti širiti riječ. Onda njihovi prijatelji pristupe i nastave širiti riječ."
Premda usporedba sa religijom može staviti Bitcoin u iracionalno svjetlo, potpuno je racionalno za individualnog vlasnika da širi dobru vijest o superiornom monetarnom dobru, i za šire društvo da se standardizira oko njega. Novac djeluje kao temelj za svu trgovinu i štednju; tako da prihvaćanje superiornog oblika novca ima ogromne multiplicirajuće benefite za stvaranje bogatstva za sve članove društva.
Oblik monetizacije
U članku o Spekulativnom prihvaćanju Bitcoina / teorije cijene, Michael Casey postulira da rastući Gartner hype ciklusi predstavljaju faze standardne S-krivulje prihvaćanja novih tehnologija, koje su bile prisutne kod mnogih transformacijskih tehnologija dok su postajale uobičajene u društvu.
Svaki Gartner hype ciklus počinje sa eksplozijom entuzijazma za novom tehnologijom, a cijenu podižu oni sudionici na tržištvu koji su “dostupni” u toj fazi. Najraniji kupci u Gartner hype ciklusu obično imaju jaku vjeru o transformacijskoj prirodi tehnologije u koju ulažu. S vremenom, tržište dosegne vrhunac entuzijazma kako se količina novih kupaca iscrpljuje, te kupovinom počnu dominirati spekulatori koji su više zainteresirani u brze profite nego u samu tehnologiju.
Nakon vrha hype ciklusa, cijene rapidno padaju dok spekulativno ludilo ustupa mjesto očajavanju, javnoj poruzi i osjećaju da tehnologija nije uopće bila transformacijska. S vremenom, cijena dosegne dno i formira plato na kojem se originalnim ulagačima, koji su imali snažno uvjerenje, pridružuju nove grupe ljudi koji su izdržali bol kraha cijena i koji cijene važnost same tehnologije.
Plato traje neko vrijeme i formira, kako Casey kaže, “stabilnu, dosadnu dolinu.” Za ovo vrijeme, javni interes za tehnologiju opada, no nastaviti će se razvijati i snažna zajednica uvjerenja će polako rasti. Tada, postavlja se nova baza za sljedeću iteraciju hype ciklusa, dok vanjski promatrači prepoznaju da tehnologija i dalje postoji i da ulaganje u nju možda nije onoliko rizično kao što se činilo za vrijeme pada cijene. Sljedeća iteracija hype ciklusa donosi mnogo veći broj novih ljudi, pa je i ciklus daleko veći u svojoj magnitudi.
Jako mali broj ljudi koji sudjeluju u Gartner hype ciklusu će točno predvidjeti koliko će visoko cijena porasti za vrijeme ciklusa. Cijene često dosegnu razine koje bi se činile apsurdnima većini ulagača u raniji stadijima ciklusa. Kada ciklus završi, mediji tipično atribuiraju pad cijene nekoj od aktualnih drušvenih tema. Premda takva tema može biti okidač pada, ona nikad nije temeljni razlog zašto ciklus završava. Gartner hype ciklusi završavaju kada je količina dostupnih novih sudionika na tržištu iscrpljena.
Zanimljivo je da je i zlato nacrtalo klasičan graf Gartner hype ciklusa od kasnih 1970-ih do ranih 2000-ih. Moguće je spekulirati da je hype ciklus osnovna socijalna dinamika oko procesa monetizacije.
Gartner kohorte
Od početka trgovanja Bitcoina na mjenjačnicama 2010. godine, Bitcoin tržište je svjedočilo četirima velikim Gartner hype ciklusima. U retrospektivi, možemo vrlo precizno identificirati grupe cijena prethodnih hype ciklusa Bitcoin tržišta. Također, možemo kvalitativno odrediti kohorte ulagača koje su povezane sa svakom iteracijom prethodnih ciklusa.
$ 0–$ 1 (2009. – 3. mjesec 2011.): Prvi hype ciklus u Bitcoin tržištu dominirali su kriptografi, računalni znanstvenici i cypherpunkovi koji su od početka bili spremni razumijeti važnost nevjerojatnog izuma Satoshija Nakamotoa, i koji su bili pioniri u potvrđivanju da Bitcoin protokol nema tehničkih mana.
$ 1–$ 30 (3. mjesec 2011. – 7. mjesec. 2011.): Drugi ciklus privukao je rane entuzijaste oko novih tehnologija kao i stabilan pritok ideološki motiviranih ulagača koji su bili oduševljeni idejom novca odvojenog od države. Libertarijanci poput Rogera Vera došli su u Bitcoin zbog aktivnog anti-institucionalnog stava, i mogućnosti koju je nova tehnologija obećavala. Wences Casares, briljantni i dobro povezani serijski poduzetnik, bio je također dio drugog Bitcoin hype ciklusa te je širio riječ o Bitcoinu među najprominentnijim tehnolozima i ulagačima u Silicijskoj Dolini.
$ 250–$ 1100 (4. mjesec 2013. – 12. mjesec 2013.): Treći hype ciklus doživio je ulazak ranih generalnih i institucionalnih ulagača koji su bili voljni uložiti trud i riskirati kroz užasno komplicirane kanale likvidnosti kako bi kupili bitcoine. Primaran izvor likvidnosti na tržištu za vrijeme ovog perioda bio je MtGox, mjenjačnica bazirana u Japanu, koju je vodio notorno nesposobni i beskrupulozni Mark Karpeles, koji je kasnije završio i u zatvoru zbog svoje uloge u kolapsu MtGoxa.
Valja primijetiti da je rast Bitcoinove cijene za vrijeme spomenuti hype ciklusa većinom povezano sa povećanjem likvidnosti i lakoćom sa kojom su ulagači mogli kupiti bitcoine. Za vrijeme prvog hype ciklusa, nisu postojale mjenjačnice; akvizicija bitcoina se odvijala primarno kroz rudarenje (mining) ili kroz izravnu razmjenu sa onima koju su već izrudarili bitcoine. Za vrijeme drugog hype ciklusa, pojavile su se rudimentarne mjenjačnice, no nabavljanje i osiguravanje bitcoina na ovim mjenjačnicama bilo je previše kompleksno za sve osim tehnološki najsposobnijih ulagača. Čak i za vrijeme trećeg hype ciklusa, ulagači koju su slali novac na MtGox kako bi kupili bitcoine su morali raditi kroz značajne prepreke. Banke nisu bile voljne imati posla sa mjenjačnicom, a oni posrednici koji su nudili usluge transfera bili su često nesposobni, kriminalni, ili oboje. Nadalje, mnogi koji su uspjeli poslati novac MtGoxu, u konačnici su morali prihvatiti gubitak svojih sredstava kada je mjenjačnica hakirana i kasnije zatvorena.
Tek nakon kolapsa MtGox mjenjačnice i dvogodišnje pauze u tržišnoj cijeni Bitcoina, razvili su se zreli i duboki izvori likvidnosti; primjeri poput reguliranih mjenjačnica kao što su GDAX i OTC brokeri kao Cumberland mining. Dok je četvrti hype ciklus započeo 2016. godine, bilo je relativno lako običnim ulagačima kupiti i osigurati bitcoine.
$ 1100 – $ 19600? (2014. –?):
U trenutku pisanja ovog teksta, tržište Bitcoina je prolazilo svoj četvrti veliki hype ciklus. Sudjelovanje u ovom hype ciklusu dominirala je ona skupina koju je Michael Casey opisao kao “rana većina” običnih i institucionalnih ulagača.
Kako su se izvori likvidnosti produbljivali i sazrijevali, veliki institucionalni ulagači sada imaju priliku sudjelovati kroz regulirana “futures” tržišta. Dostupnosti takvih tržišta stvara put ka kreaciji Bitcoin ETF-a (exchange traded fund) (fond na slobodnom tržištu), koji će onda pokrenuti “kasnu većinu” i “najsporije” u sljedećim hype ciklusima.
Premda je nemoguće predvidjeti točan efekt budućih hype ciklusa, razumno je očekivati da će najviša točka biti između $ 20.000 i $ 50.000 (2021. zenit je bio preko $ 69.000). Znatno više od ovog raspona, i Bitcoin bi imao znatan postotak ukupne vijednosti zlata (zlato i Bitcoin bi imali jednaku tržišnu kapitalizaciju kada bi bitcoini vrijedili oko $ 380.000 u trenutku pisanja ovog teksta). Značajan postotak vrijednosti zlata dolazi od potražnje centralnih banaka, te je malo vjerojatno da će centralne banke ili suverene države sudjelovati u trenutnom hype ciklusu.
Ulazak suverenih država u Bitcoin
Bitcoinov zadnji Gartner hype ciklus će započeti kada ga suverene države počnu akumulirati kao dio svojih rezervi stranih valuta. Tržišna kapitalizacija Bitcoina je trenutno premala da bismo ga smatrali značajnim dodatkom rezervama većini zemalja. No, kako se interes u privatnom sektoru povećava i kapitalizacija Bitcoina se približi trilijunu dolara, postat će dovoljno likvidan za većinu država. Prva država koja službeno doda bitcoine u svoje rezerve će vjerojatno potaknuti stampedo ostalih da učine isto. Države koje su među prvima u usvajanju Bitcoina imat će najviše benefita u svojim knjigama ako Bitcoin u konačnici postane globalna valuta (global reserve currency). Nažalost, vjerojatno će države sa najjačom izvršnom vlasti - diktature poput Sjeverne Koreje - biti najbrže u akumulaciji bitcoina. Neodobravanje prema takvim državama i slaba izvršna tijela zapadnjačkih demokracija uzrokovat će sporost i kašnjenje u akumulaciji bitcoina za njihove vlastite rezerve.
Velika je ironija u tome što je SAD trenutno jedna od regulatorno najotvorenijih nacija prema Bitcoinu, dok su Kina i Rusija najzatvorenije. SAD riskira najviše, geopolitički, ako bi Bitcoin zamijenio dolar kao svjetska rezervna valuta. U 1960-ima, Charles de Gaulle je kritizirao “pretjeranu privilegiju” (“exorbitant privilege”) koju su SAD imale u međunarodnom monetarnom poretku, postavljenom kroz Bretton Woods dogovor 1944. godine. Ruska i kineska vlada još ne shvaćaju geo-strateške benefite Bitcoina kao rezervne valute, te se trenutno brinu o efektima koje bi mogao imati na njihova unutarnja tržišta. Kao de Gaulle u 1960-ima, koji je prijetio SAD-u povratkom na klasični standard zlata, Kinezi i Rusi će s vremenom uvidjeti korist u velikoj poziciji u Bitcoinu - spremištu vrijednosti bez pokrića ijedne vlade. Sa najvećom koncentracijom rudara Bitcoina u Kini (2017.), kineska vlada već ima znatnu potencijalnu prednost u stavljanju bitcoina u svoje rezerve.
SAD se ponosi svojim statusom nacije inovatora, sa Silicijskom dolinom kao krunom svoje ekonomije. Dosad, Silicijska dolina je dominirala konverzacijom usmjerenom prema regulaciji, i poziciji koju bi ona treba zauzeti prema Bitcoinu. No, bankovna industrija i federalna rezerva SAD-a (US Federal Reserve, Fed) napokon počinju uviđati egzistencijalnu prijetnju koju Bitcoin predstavlja za američku monetarnu politiku, postankom globalne rezervne valute. Wall Street Journal, jedan od medijskih glasova federalne reserve, izdao je komentar o Bitcoinu kao prijetnji monetarnoj politici SAD-a:
"Postoji još jedna opasnost, možda i ozbiljnija iz perspektive centralnih banaka i regulatora: bitcoin možda ne propadne. Ako je spekulativni žar u kriptovalutu samo prvi pokazatelj njezinog šireg korištenja kao alternative dolaru, Bitcoin će svakako ugroziti monopol centralnih banaka nad novcem."
U narednim godinama, možemo očekivati veliku borbu između poduzetnika i inovatora u Silicijskoj dolini, koji će pokušavati čuvati Bitcoin od državne kontrole s jedne strane, i bankovne industrije i centralnih banaka koje će učiniti sve što mogu da bi regulirale Bitcoin kako bi spriječile znatne promjene u svojoj industriji i moći izdavanja novca, s druge.
Prijelaz na medij razmjene
Monetarno dobro ne može postati opće prihvaćen medij razmjene (standardna ekonomska definicija za “novac”) prije nego je vrednovano od širokog spektra ljudi; jednostavno, dobro koje nije vrednovano neće biti prihvaćeno u razmjeni. Kroz proces generalnog rasta vrijednosti, i time postanka spremišta vrijednosti, monetarno dobro će brzo narasti u kupovnoj moći, i time stvoriti cijenu za korištenje u razmjeni. Samo kada ta cijena rizika mijenjanja spremišta vrijednosti padne dovoljno nisko, može dobro postati opće prihvaćen medij razmjene.
Preciznije, monetarno dobro će biti prikladno kao medij razmjene samo kada je suma cijene rizika i transakcijske cijene u razmjeni manja nego u trgovini bez tog dobra.
U društvu koje vrši robnu razmjenu, prijelaz spremišta vrijednosti u medij razmjene može se dogoditi čak i onda kada monetarno dobro raste u kupovnoj moći, zato što su transakcijski troškovi robne razmjene iznimno visoki. U razvijenoj ekonomiji, u kojoj su troškovi razmjene niski, moguće je za mladu i rapidno rastućnu tehnologiju spremišta vrijednosti, poput Bitcoina, da se koristi kao medij razmjene, doduše na ograničen način. Jedan primjer je ilegalno tržište droge, gdje su kupci voljni žrtvovati oportunu cijenu čuvanja bitcoina kako bi umanjili znatan rizik kupovine droge koristeći fiat novac.
Postoje međutim velike institucionalne barijere da novonastalo spremište vrijednosti postane sveopće prihvaćen medij razmjene u razvijenom društvu. Države koriste oporezivanje kao moćnu metodu zaštite svojeg suverenog novca protiv rivalskih monetarnih dobara. Ne samo da suvereni novac ima prednost konstantnog izvora potražnje, zato što je porez moguće platiti jedino u njemu, nego su i rivalska monetarna dobra oporezana pri svakoj razmjeni za vrijeme rastuće cijene. Ova metoda oporezivanja stvara znatan otpor korištenju spremišta vrijednosti kao medija razmjene.
Ovakvo sabotiranje tržišnih monetarnih dobara nije nepremostiva barijera za njihovo prihvaćanje kao općeg medija razmjene. Ako ljudi izgube vjeru u suvereni novac, njegova vrijednost može rapidno propasti kroz proces zvan hiperinflacija. Kada suvereni novac prolazi kroz hiperinflaciju, njegova vrijednost propadne prvo u usporedbi sa najlikvidnijim dobrima u društvu, kao što je zlato ili stabilna strana valuta (američki dolar npr.), ako su ona dostupna. Kada nema likvidnih dobara ili ih ima premalo, novac u hiperinflaciji kolabira u usporedbi sa stvarnim dobrima, kao što su nekretnine ili upotrebljiva roba. Arhetipska slika hiperinflacije je trgovina sa praznim policama - potrošači brzo bježe iz propadajuće vrijednosti novca svoje nacije.
Nakon dovoljno vremena, kada je vjera potpuno uništena za vrijeme hiperinflacije, suvereni novac više nitko ne prihvaća, te se društvo može vratiti na robnu razmjenu, ili će doživjeti potpunu zamjenu monetarne jedinice za sredstvo razmjene. Primjer ovog procesa bila je zamjena zimbabveanskog dolara za američki dolar. Takva promjena suverenog novca za stranu valutu je dodatno otežana relativnom oskudnošću strane valute i odsustvom stranih bankarskih institucija koje pružaju likvidnost tržištu.
Sposobnost lakog prenošenja bitcoina preko granica i odsustvo potrebe za bankarskim sustavom čine Bitcoin idealnim monetarnim dobrom za one ljude koji pate pod hiperinflacijom. U nadolazećim godinama, kako fiat valute nastave svoj povijesni trend ka bezvrijednosti, Bitcoin će postati sve popularniji izbor za ušteđevine ljudi diljem svijeta. Kada je novac nacije napušten i zamijenjen Bitcoinom, Bitcoin će napraviti tranziciju iz spremišta vrijednosti u tom društvu u opće prihvaćeno sredstvo razmjene. Daniel Krawicz stvorio je termin “hiperbitcoinizacija” da bi opisao ovaj proces.
Učestala pogrešna shvaćanja
Većina ovog članka usredotočila se na monetarnu prirodu Bitcoina. Sa tim temeljima možemo adresirati neke od najčešćih nerazumijevanja u Bitcoinu.
Bitcoin je balon (bubble)
Bitcoin, kao sva tržišna monetarna dobra, posjeduje monetarnu premiju. Ona često rezultira uobičajenom kritikom da je Bitcoin samo “balon.” No, sva monetarna dobra imaju monetarnu premiju. Naprotiv, ta monetarna premija (cijena viša od one koju diktira potražnja za dobrom kao korisnim) je upravo karakteristična za sve oblike novca. Drugim riječima, novac je uvijek i svuda balon. Paradoksalno, monetarno dobro je istovremeno balon i ispod vrijednosti ukoliko je u ranijim stadijima općeg prihvaćanja kao novac.
Bitcoin je previše volatilan
Volatilnost cijene Bitcoina je funkcija njegovog nedavnog nastanka. U prvih nekoliko godina svojeg postojanja, Bitcoin se ponašao kao mala dionica, i svaki veliki kupac - kao npr. braća Winklevoss - mogao je uzrokovati veliki skok u njegovoj cijeni. No, kako su se prihvaćenost i likvidnost povećavali kroz godine, volatilnost Bitcoina je srazmjerno smanjila. Kada Bitcoin postigne tržišnu kapitalizaciju (vrijednost) zlata, imat će sličnu volatilnost kao i zlato. Kako Bitcoin nastavi rasti, njegova volatilnost će se smanjiti do razine koja ga čini prikladnim za široko korištenje kao medij razmjene. Kao što je prethodno rečeno, monetizacija Bitcoina se odvija u seriji Gartner hype ciklusa. Volatilnost je najniža za vrijeme vrhunaca i dolina unutar ciklusa. Svaki hype ciklus ima nižu volatilnost od prethodnih, zato što je likvidnost tržišta veća.
Cijene transakcija su previsoke
Novija kritika Bitcoin mreže je ta da ju je povećanje cijena prijenosa bitcoina učinilo neprikladnom za sustav plaćanja. No, rast u cijenama transakcija je zdrav i očekivan. One su nužne za plaćanje bitcoin minera (rudara), koji osiguravaju mrežu validacijom transakcija. Rudare se plaća kroz cijene transakcija ili kroz blok-nagrade, koje su inflacijska subvencija od trane trenutnih vlasnika bitcoina.
S obzirom na Bitcoinovu fiksnu proizvodnju (monetarna politika koja ga čini idealnim za spremanje vrijednosti), blok-nagrade će s vremenom nestati i mrežu će se u konačnici morati osiguravati kroz cijene transakcija. Mreža sa “niskim” cijenama transakcija je mreža sa slabom sigurnosti i osjetljiva na vanjsku intervenciju i cenzuru. Oni koji hvale niske cijene Bitcoinovih alternative zapravo niti ne znajući opisuju slabosti tih takozvanih “alt-coina.”
Površan temelj kritika Bitcoinovih “visokih” cijena transakcija je uvjerenje da bi Bitcoin trebao biti prvo sustav plaćanja, i drugo spremište vrijednosti. Kao što smo vidjeli kroz povijest novca, ovo uvjerenje je naopako. Samo onda kada Bitcoin postane duboko ukorijenjeno spremište novca može biti prikladan kao sredstvo razmjene. Nadalje, kada oportunitetni trošak razmjene bitcoina dođe na razinu koja ga čini prikladnim sredstvom razmjene, većina trgovine neće se odvijati na samoj Bitcoin mreži, nego na mrežama “drugog sloja” (second layer) koje će imati niže cijene transakcija. Takve mreže, poput Lightning mreže, služe kao moderna verzija zadužnica koje su korištene za prijenos vlasničkih papira zlata u 19. stoljeću. Banke su koristile zadužnice zato što je prijenos samog metala bio daleko skuplji. Za razliku od takvih zadužnica, Lightning mreža će omogućavati nisku cijenu prijenosa bitcoina bez potrebe za povjerenjem prema trećoj strani, poput banaka. Razvoj Lightning mreže je tehnološka inovacija od izuzetne važnosti u povijesti Bitcoina, i njezina vrijednost će postati očita u narednim godinama, kako je sve više ljudi bude razvijalo i koristilo.
Konkurencija
Pošto je Bitcoin softverski protokol otvorenog tipa (open-source), oduvijek je bilo moguće kopirati softver i imitirati mrežu. Kroz godine nastajali su mnogi imitatori, od identičnih kopija, kao Litecoin, do kompleksnijih varijanti kao što je Ethereum, koje obećavaju arbitrarno kompleksne ugovorne mehanizme koristeći decentralizirani računalni sustav. Česta kritika Bitcoinu od strane ulagača je ta da on ne može zadržati svoju vrijednost kada je vrlo lako stvoriti konkurente koji mogu lako i brzo u sebi imati najnovije inovacije i softverske funkcionalnosti.
Greška u ovom argumentu leži u manju takozvanog “mrežnog efekta” (network effect), koji postoji u prvoj i dominantnoj tehnologiji u nekom području. Mrežni efekt - velika vrijednost korištenja Bitcoina samo zato što je već dominantan - je važno svojstvo samo po sebi. Za svaku tehnologiju koja posjeduje mrežni efekt, to je daleko najvažnije svojstvo koje može imati.
Za Bitcoin, mrežni efekt uključuje likvidnost njegovog tržišta, broj ljudi koji ga posjeduju, i zajednicu programera koji održavaju i unaprjeđuju njegov softver i svjesnost u javnosti. Veliki ulagači, uključujući države, će uvijek prvo tražiti najlikvidnije tržište, kako bi mogli ući i izaći iz tržišta brzo, i bez utjecanja na cijenu. Programeri će se pridružiti dominantnoj programerskoj zajednici sa najboljim talentom, i time pojačati samu zajednicu. Svjesnost o brendu sama sebe pojačava, pošto se nadobudni konkurenti Bitcoina uvijek spominju u kontekstu Bitcoina kao takvog.
Raskrižje na putu (fork)
Trend koji je postao popularan 2017. godine nije bio samo imitacija Bitcoinovog softvera, nego kopiranje potpune povijesti njegovih prošlih transakcija (cijeli blockchain). Kopiranjem Bitcoinovog blockchaina do određene točke/bloka i odvajanjem sljedećih blokova ka novoj mreži, u procesu znanom kao “forking” (odvajanje), Bitcoinovi konkurenti su uspjeli riješiti problem distribuiranja svojeg tokena velikom broju korisnika.
Najznačajniji takav fork dogodio se 1. 8. 2017. godine, kada je nova mreža nazvana Bitcoin Cash (Bcash) stvorena. Vlasnik N količine bitcoina prije 1.8.2017. bi onda posjedovao N bitcoina i N BCash tokena. Mala, ali vrlo glasna zajednica Bcash proponenata je neumorno pokušavala prisvojiti Bitcoinov brend i ime, imenujući svoju novu mrežu Bitcoin Cast i pokušavajući uvjeriti nove pridošlice u Bitcoin da je Bcash “pravi” Bitcoin. Ti pokušaji su većinom propali, i taj neuspjeh se vidi u tržišnim kapitalizacijama dviju mreža. No, za nove ulagače, i dalje postoji rizik da bi konkurent mogao kopirati Bitcoin i njegov blockchain i tako uspjeti u preuzimanju tržišne kapitalizacije, te postati de facto Bitcoin.
Moguće je uočiti važno pravilo gledajući velike forkove u prošlosti Bitcoin i Ethereum mreža. Većina tržišne kapitalizacije odvijat će se na mreži koja zadrži najviši stupanj talenta i aktivnosti u zajednici programera. Premda se na Bitcoin može gledati kao na nov i mlad novac, on je također računalna mreža koja počiva na softveru, kojeg se pak treba održavati i poboljšavati. Kupovina tokena na mreži koja ima malo neiskusnih programera bilo bi kao kupovati kopiju Microsoft Windowsa na kojoj rade lošiji programeri. Jasno je vidljivo iz povijesti forkova koji su se odvili 2017. godine da su najbolji računalni i kriptografski stručnjaci posvećeni razvoju originalnog Bitcoina, a ne nekoj od rastućeg broja imitacija koje su se izrodile iz njega.
Stvarni rizici
Premda su uobičajene kritike upućene Bitconu od strane medija i ekonomske profesije krive i bazirane na netočnom shvaćanju novca, postoje pravi i značajni rizici kod ulaganja u Bitcoin. Bilo bi mudro za novog Bitcoin ulagača da shvati ove rizike prije potencijalnog ulaganja.
Rizik protokola
Bitcoin protokol i kriptografski sastavni dijelovi na kojima je sagrađen potencijalno imaju dosad nepronađenu grešku u svom dizajnu, ili mogu postati nesigurni razvojem kvantnih računala. Ako se pronađe greška u protokolu, ili neka nova metoda računarstva učini mogućim probijanje kriptografskih temelja Bitcoina, vjera u Bitcoin biti će znatno narušena. Rizik protokola bio je najviši u ranim godinama razvoja Bitcoina, kada je još uvijek bilo nejasno, čak i iskusnim kriptografima, je li Satoshi Nakamoto zaista riješio problem bizantskih generala (Byzantine Generals’ Problem). Brige oko ozbiljnih grešaka u Bitcoin protokolu nestale su kroz godine, no uzevši u obzir njegovu tehnološku prirodu, rizik protokola će uvijek ostati u Bitcoinu, makar i kao izuzetak.
Propadanje mjenjačnica
Time što je decentraliziran, Bitcoin je pokazao značajnu otpornost, suočen sa brojnim pokušajima raznih vlada da ga reguliraju ili unište. No, mjenjačnice koje trguju bitcoinima za fiat valute su centralizirani entiteti i podložne regulacijama i zatvaranju. Bez mjenjačnica i volje bankara da s njima posluju, proces monetizacije Bitcoina bio bi ozbiljno usporen, ako ne i potpuno zaustavljen. Iako postoje alternativni izvori likvidnosti za Bitcoin, poput “over-the-counter” brokera i decentraliziranih tržišta za kupovinu i prodaju bitcoina, kritičan proces otkrivanja i definiranja cijene se odvija na najlikvidnijim mjenjačnicama, koje su sve centralizirane.
Jedan od načina za umanjivanje rizika gašenja mjenjačnica je geografska arbitraža. Binance, jedna od velikih mjenjačnica iz Kine, preselila se u Japan nakon što joj je kineska vlada zabranila operiranje u Kini. Vlade su također oprezne kako ne bi ugušile novu industriju koja je potencijalno značajna kao i internet, i time predale nevjerojatnu konkurentnu vrijednost drugim nacijama.
Samo kroz koordinirano globalno ukidanje Bitcoin mjenjačnica bi proces monetizacije mogao biti zaustavljen. Trenutno smo u utrci; Bitcoin raste i postaje sve rašireniji, i doći će do trenutka kada bi potpuno ukidanje mjenjačnica postalo politički neizvedivo - kao i gašenje interneta. Mogućnost takvog ukidanja je još uvijek realna, i valja je uzeti u obzir pri ulaganju u Bitcoin. Kao što je gore objašnjeno, suverene vlade se polako bude i uviđaju prijetnju koju predstavlja neovisna digitalna valuta otporna na cenzuru, za njihovu monetarnu politiku. Otvoreno je pitanje hoće li išta poduzeti da odgovore ovoj prijetnji prije nego Bitcoin postane toliko utvrđen i raširen da politička akcija postane nemoćna i ne-efektivna.
Zamjenjivost
Otvorena i transparentna priroda Bitcoin blockchaina omogućava državama da proglase specifične bitcoine “okaljanima” zbog njihovog korištenja u određenim aktivnostima. Premda Bitcoin, na protokolarnoj razini, ne diskriminira transakcije na ikoji način, “okaljani” bitcoini bi mogli postati bezvrijedni ako bi ih regulacije proglasile ilegalnima i neprihvatljivima za mjenjačnice ili trgovce. Bitcoin bi tada izgubio jedno od kritičnih svojstava monetarnog dobra: zamjenjivost.
Da bi se ovaj problem riješio i umanjio, biti će potrebna poboljšanja na razini protokola kako bi se poboljšala privatnost transakcija. Premda postoji napredak u ovom smjeru, prvi put primjenjen u digitalnim valutama kao što su Monero i Zcash, potrebno je napraviti značajne tehnološke kompromise između efikasnosti i kompleksnosti Bitcoina i njegove privatnosti. Pitanje ostaje otvoreno je li moguće dodati nova svojstva privatnosti na Bitcoin, na način koji neće kompromitirati njegovu korisnost kao novca.
Zaključak
Bitcoin je novonastali novac koji je u procesu transformacije iz sakupljačkog dobra u spremište vrijednosti. Kao neovisno monetarno dobro, moguće je da će u budućnosti postati globalan novac, slično kao zlato za vrijeme 19. stoljeća. Prihvaćanje Bitcoina kao globalnog novca je upravo taj optimističan scenarij za Bitcoin, kojeg je artikulirao Satoshi Nakamoto još 2010. godine u email razmjeni sa Mikeom Hearnom:
"Ako zamisliš da se koristi u nekom dijelu svjetske trgovine, i da će postojati samo 21 milijun bitcoina za cijeli svijet, vrijednost po jedinici će biti znatno veća".
Ovaj scenarij je još snažnije definirao briljantni kriptograf Hal Finney, koji je ujedno primio i prve bitcoine od Nakamotoa, ubrzo nakon najave prvog funkcionalnog Bitcoin softvera:
"Zamislimo da Bitcoin bude uspješan i postane dominantan sustav plaćanja diljem svijeta. U tom slučaju će ukupna vrijednost valute biti jednaka ukupnoj vrijednosti svog bogatstva svijeta. Današnje procjene ukupnog svjetskog bogatska kućanstava koje sam pronašao borave negdje između 100 i 300 trilijuna dolara. Sa 20 milijuna bitcoina, svaki bi onda vrijedio oko 10 milijuna dolara."
Čak i da Bitcoin ne postane u cijelost globalan novac, nego da se samo natječe sa zlatom kao neovisno spremište vrijednosti, i dalje je masivno podcijenjen. Mapiranje tržišne kapitalizacije postojeće količine izrudarenog zlata (oko 8 trilijuna dolara) na maksimalnu dostupnost Bitcoina od 21 milijun, daje vrijednost od otprilike 380,000 dolara po bitcoinu. Kao što smo vidjeli u prethodnom tekstu, svojstva koja omogućavaju monetarnom dobru da bude prikladno spremište vrijednosti, čine Bitcoin superiornijim zlatu u svakom pogledu osim trajanja povijesti. No, kako vrijeme prolazi i Lindy efekt postane jači, dosadašnja povijest će prestati biti prednost zlata. Samim time, nije nerazumno očekivati da će Bitcoin narasti do, a možda i preko, ukupne cijene zlata na tržištvu do 2030. Opaska ovoj tezi je činjenica da veliki postotak vrijednosti zlata dolazi od toga što ga centralne banke čuvaju kao spremište vrijednosti. Da bi Bitcoin došao do te razine, određena količina suverenih država će trebati sudjelovati. Hoće li zapadnjačke demokracije sudjelovati u vlasništvu Bitcoina je nepoznato. Vjerojatnije je, nažalost, da će prve nacije u Bitcoin tržištu biti sitne diktature i kleptokracije.
Ako niti jedna država ne bude sudjelovala u Bitcoin tržištu, optimistična teza i dalje postoji. Kao nevisno spremište vrijednosti u rukama individualnih i institucionalnih ulagača, Bitcoin je i dalje vrlo rano u svojoj “krivulji prihvaćenosti” (adoption curve); tzv. “rana većina” ulaze na tržište sada, dok će ostali ući tek nekoliko godina kasnije. Sa širim sudjelovanjem individualnih i institucionalnih ulagača, cijena po bitcoinu između 100,000 i 200,000 dolara je sasvim moguća.
Posjedovanje bitcoina je jedna od malobrojnih asimetričnih novčanih strategija dostupnih svakome na svijetu. Poput “call” opcija, negativan rizik ulagača je ograničen na 1x, dok potencijalna dobit i dalje iznosi 100x ili više. Bitcoin je prvi istinski globalan balon čija je veličina ograničena samo potražnjom i željom građana svijeta da zaštite svoju ušteđevinu od raznovrsnih ekonomskih malverzacija vlade. Bitcoin je ustao kao feniks iz pepela globalne financijske krize 2008. godine - katastrofe kojoj su prethodile odluke centralnih banaka poput američke Federalne rezerve (Federal Reserve).
Onkraj samo financijske teze za Bitcoin, njegov rast i uspjeh kao neovisno spremište vrijednosti imat će duboke geopolitičke posljedice. Globalna, ne-inflacijska valuta će prisiliti suverene države da promjene svoje primarne mehanizme financiranja od inflacije u izravno oporezivanje; koje je daleko manje politički popularno. Države će se smanjivati proporcionalno političkoj boli koju im nanese oporezivanje kao jedini način financiranja. Nadalje, globalna trgovina vršiti će se na način koji zadovoljava aspiraciju Charlesa de Gaullea, da nijedna nacija ne bi smjela imati privilegiju nad ikojom drugom:
"Smatramo da je potrebno da se uspostavi međunarodna trgovina, kao što je bio slučaj prije velikih nesreća koje su zadesile svijet, na neosporivoj monetarnoj bazi, koja ne nosi na sebi oznaku ijedne države."
Za 50 godina, ta monetarna baza biti će Bitcoin.

2025-05-07 06:16:30Here’s Sean Voisen writing about how programming is a feeling:
For those of us who enjoy programming, there is a deep satisfaction that comes from solving problems through well-written code, a kind of ineffable joy found in the elegant expression of a system through our favorite syntax. It is akin to the same satisfaction a craftsperson might find at the end of the day after toiling away on well-made piece of furniture, the culmination of small dopamine hits that come from sweating the details on something and getting them just right. Maybe nobody will notice those details, but it doesn’t matter. We care, we notice, we get joy from the aesthetics of the craft.
This got me thinking about the idea of satisfaction in craft. Where does it come from?

2025-02-17 17:12:01President Trump has intensified immigration enforcement, likening it to a wartime effort. Despite pouring resources into the U.S. Immigration and Customs Enforcement (ICE), arrest numbers are declining and falling short of goals. ICE fell from about 800 daily arrests in late January to fewer than 600 in early February.
Critics argue the administration is merely showcasing efforts with ineffectiveness, while Trump seeks billions more in funding to support his deportation agenda. Increased involvement from various federal agencies is intended to assist ICE, but many lack specific immigration training.
Challenges persist, as fewer immigrants are available for quick deportation due to a decline in illegal crossings. Local sheriffs are also pressured by rising demands to accommodate immigrants, which may strain resources further.

2025-05-06 06:00:25Album art didn’t always exist. In the early 1900s, recorded music was still a novelty, overshadowed by sales of sheet music. Early vinyl records were vastly different from what we think of today: discs were sold individually and could only hold up to four minutes of music per side. Sometimes, only one side of the record was used. One of the most popular records of 1910, for example, was “Come, Josephine, in My Flying Machine”: it clocked in at two minutes and 39 seconds.
The invention of album art can get lost in the story of technological mastery. But among all the factors that contributed to the rise of recorded music, it stands as one of the few that was wholly driven by creators themselves. Album art — first as marketing material, then as pure creative expression — turned an audio-only medium into a multi-sensory experience.
This is the story of the people who made music visible.

2025-05-06 05:49:01I don’t like garlic. It’s not a dislike for the taste in the moment, so much as an extreme dislike for the way it stays with you—sometimes for days—after a particularly garlicky meal.
Interestingly enough, both of my brothers love garlic. They roast it by itself and keep it at the ready so they can have a very strong garlic profile in their cooking. When I prepare a dish, I don’t even see garlic on the ingredient list. I’ve cut it out of my life so completely that my brain genuinely skips over it in recipes. While my brothers are looking for ways to sneak garlic into everything they make, I’m subconsciously avoiding it altogether.
A few years back, when I was digging intensely into how design systems mature, I stumbled on the concept of a design system origin story. There are two extreme origin stories and an infinite number of possibilities between. On one hand you have the grassroots system, where individuals working on digital products are simply trying to solve their own daily problems. They’re frustrated with having to go cut and paste elements from past designs or with recreating the same layouts over and over, so they start to work more systematically. On the other hand, you have the top down system, where leadership is directing teams to take a more systematic approach, often forming a small partially dedicated core team to tackle some centralized assets and guidelines for all to follow. The influences in those early days bias a design system in interesting and impactful ways.
We’ve established that there are a few types of bias that are either intentionally or unintentionally embedded into our design systems. Acknowledging this is a great first step. But, what’s the impact of this? Does it matter?
I believe there are a few impacts design system biases, but there’s one that stands out. The bias in your design system makes some individuals feel the system is meant for them and others feel it’s not. This is a problem because, a design system cannot live up to it’s expected value until it is broadly in use. If individuals feel your design system is not for them, the won’t use it. And, as you know, it doesn’t matter how good your design system is if nobody is using it.

2025-02-15 07:02:08E-cash are coupons or tokens for Bitcoin, or Bitcoin debt notes that the mint issues. The e-cash states, essentially, "IoU 2900 sats".
They're redeemable for Bitcoin on Lightning (hard money), and therefore can be used as cash (softer money), so long as the mint has a good reputation. That means that they're less fungible than Lightning because the e-cash from one mint can be more or less valuable than the e-cash from another. If a mint is buggy, offline, or disappears, then the e-cash is unreedemable.
It also means that e-cash is more anonymous than Lightning, and that the sender and receiver's wallets don't need to be online, to transact. Nutzaps now add the possibility of parking transactions one level farther out, on a relay. The same relays that cannot keep npub profiles and follow lists consistent will now do monetary transactions.
What we then have is * a transaction on a relay that triggers * a transaction on a mint that triggers * a transaction on Lightning that triggers * a transaction on Bitcoin.
Which means that every relay that stores the nuts is part of a wildcat banking system. Which is fine, but relay operators should consider whether they wish to carry the associated risks and liabilities. They should also be aware that they should implement the appropriate features in their relay, such as expiration tags (nuts rot after 2 weeks), and to make sure that only expired nuts are deleted.
There will be plenty of specialized relays for this, so don't feel pressured to join in, and research the topic carefully, for yourself.

2025-05-06 01:37:28I remember the first gathering of Nostr devs two years ago in Costa Rica. We were all psyched because Nostr appeared to solve the problem of self-sovereign online identity and decentralized publishing. The protocol seemed well-suited for textual content, but it wasn't really designed to handle binary files, like images or video.
The Problem
When I publish a note that contains an image link, the note itself is resilient thanks to Nostr, but if the hosting service disappears or takes my image down, my note will be broken forever. We need a way to publish binary data without relying on a single hosting provider.
We were discussing how there really was no reliable solution to this problem even outside of Nostr. Peer-to-peer attempts like IPFS simply didn't work; they were hopelessly slow and unreliable in practice. Torrents worked for popular files like movies, but couldn't be relied on for general file hosting.
Awesome Blossom
A year later, I attended the Sovereign Engineering demo day in Madeira, organized by Pablo and Gigi. Many projects were presented over a three hour demo session that day, but one really stood out for me.
Introduced by hzrd149 and Stu Bowman, Blossom blew my mind because it showed how we can solve complex problems easily by simply relying on the fact that Nostr exists. Having an open user directory, with the corresponding social graph and web of trust is an incredible building block.
Since we can easily look up any user on Nostr and read their profile metadata, we can just get them to simply tell us where their files are stored. This, combined with hash-based addressing (borrowed from IPFS), is all we need to solve our problem.
How Blossom Works
The Blossom protocol (Blobs Stored Simply on Mediaservers) is formally defined in a series of BUDs (Blossom Upgrade Documents). Yes, Blossom is the most well-branded protocol in the history of protocols. Feel free to refer to the spec for details, but I will provide a high level explanation here.
The main idea behind Blossom can be summarized in three points:
- Users specify which media server(s) they use via their public Blossom settings published on Nostr;
- All files are uniquely addressable via hashes;
- If an app fails to load a file from the original URL, it simply goes to get it from the server(s) specified in the user's Blossom settings.
Just like Nostr itself, the Blossom protocol is dead-simple and it works!
Let's use this image as an example:
If you look at the URL for this image, you will notice that it looks like this:
blossom.primal.net/c1aa63f983a44185d039092912bfb7f33adcf63ed3cae371ebe6905da5f688d0.jpg
All Blossom URLs follow this format:
[server]/[file-hash].[extension]
The file hash is important because it uniquely identifies the file in question. Apps can use it to verify that the file they received is exactly the file they requested. It also gives us the ability to reliably get the same file from a different server.
Nostr users declare which media server(s) they use by publishing their Blossom settings. If I store my files on Server A, and they get removed, I can simply upload them to Server B, update my public Blossom settings, and all Blossom-capable apps will be able to find them at the new location. All my existing notes will continue to display media content without any issues.
Blossom Mirroring
Let's face it, re-uploading files to another server after they got removed from the original server is not the best user experience. Most people wouldn't have the backups of all the files, and/or the desire to do this work.
This is where Blossom's mirroring feature comes handy. In addition to the primary media server, a Blossom user can set one one or more mirror servers. Under this setup, every time a file is uploaded to the primary server the Nostr app issues a mirror request to the primary server, directing it to copy the file to all the specified mirrors. This way there is always a copy of all content on multiple servers and in case the primary becomes unavailable, Blossom-capable apps will automatically start loading from the mirror.
Mirrors are really easy to setup (you can do it in two clicks in Primal) and this arrangement ensures robust media handling without any central points of failure. Note that you can use professional media hosting services side by side with self-hosted backup servers that anyone can run at home.
Using Blossom Within Primal
Blossom is natively integrated into the entire Primal stack and enabled by default. If you are using Primal 2.2 or later, you don't need to do anything to enable Blossom, all your media uploads are blossoming already.
To enhance user privacy, all Primal apps use the "/media" endpoint per BUD-05, which strips all metadata from uploaded files before they are saved and optionally mirrored to other Blossom servers, per user settings. You can use any Blossom server as your primary media server in Primal, as well as setup any number of mirrors:
## Conclusion
For such a simple protocol, Blossom gives us three major benefits:
- Verifiable authenticity. All Nostr notes are always signed by the note author. With Blossom, the signed note includes a unique hash for each referenced media file, making it impossible to falsify.
- File hosting redundancy. Having multiple live copies of referenced media files (via Blossom mirroring) greatly increases the resiliency of media content published on Nostr.
- Censorship resistance. Blossom enables us to seamlessly switch media hosting providers in case of censorship.
Thanks for reading; and enjoy! 🌸

2025-02-09 16:50:04There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

2025-05-02 20:05:22Du bist recht appetitlich oben anzuschauen, \ doch unten hin die Bestie macht mir Grauen. \ Johann Wolfgang von Goethe
Wie wenig bekömmlich sogenannte «Ultra-Processed Foods» wie Fertiggerichte, abgepackte Snacks oder Softdrinks sind, hat kürzlich eine neue Studie untersucht. Derweil kann Fleisch auch wegen des Einsatzes antimikrobieller Mittel in der Massentierhaltung ein Problem darstellen. Internationale Bemühungen, diesen Gebrauch zu reduzieren, um die Antibiotikaresistenz bei Menschen einzudämmen, sind nun möglicherweise gefährdet.
Leider ist Politik oft mindestens genauso unappetitlich und ungesund wie diverse Lebensmittel. Die «Corona-Zeit» und ihre Auswirkungen sind ein beredtes Beispiel. Der Thüringer Landtag diskutiert gerade den Entwurf eines «Coronamaßnahmen-Unrechtsbereinigungsgesetzes» und das kanadische Gesundheitsministerium versucht, tausende Entschädigungsanträge wegen Impfnebenwirkungen mit dem Budget von 75 Millionen Dollar unter einen Hut zu bekommen. In den USA soll die Zulassung von Covid-«Impfstoffen» überdacht werden, während man sich mit China um die Herkunft des Virus streitet.
Wo Corona-Verbrecher von Medien und Justiz gedeckt werden, verfolgt man Aufklärer und Aufdecker mit aller Härte. Der Anwalt und Mitbegründer des Corona-Ausschusses Reiner Fuellmich, der seit Oktober 2023 in Untersuchungshaft sitzt, wurde letzte Woche zu drei Jahren und neun Monaten verurteilt – wegen Veruntreuung. Am Mittwoch teilte der von vielen Impfschadensprozessen bekannte Anwalt Tobias Ulbrich mit, dass er vom Staatsschutz verfolgt wird und sich daher künftig nicht mehr öffentlich äußern werde.
Von der kommenden deutschen Bundesregierung aus Wählerbetrügern, Transatlantikern, Corona-Hardlinern und Russenhassern kann unmöglich eine Verbesserung erwartet werden. Nina Warken beispielsweise, die das Ressort Gesundheit übernehmen soll, diffamierte Maßnahmenkritiker als «Coronaleugner» und forderte eine Impfpflicht, da die wundersamen Injektionen angeblich «nachweislich helfen». Laut dem designierten Außenminister Johann Wadephul wird Russland «für uns immer der Feind» bleiben. Deswegen will er die Ukraine «nicht verlieren lassen» und sieht die Bevölkerung hinter sich, solange nicht deutsche Soldaten dort sterben könnten.
Eine wichtige Personalie ist auch die des künftigen Regierungssprechers. Wenngleich Hebestreit an Arroganz schwer zu überbieten sein wird, dürfte sich die Art der Kommunikation mit Stefan Kornelius in der Sache kaum ändern. Der Politikchef der Süddeutschen Zeitung «prägte den Meinungsjournalismus der SZ» und schrieb «in dieser Rolle auch für die Titel der Tamedia». Allerdings ist, anders als noch vor zehn Jahren, die Einbindung von Journalisten in Thinktanks wie die Deutsche Atlantische Gesellschaft (DAG) ja heute eher eine Empfehlung als ein Problem.
Ungesund ist definitiv auch die totale Digitalisierung, nicht nur im Gesundheitswesen. Lauterbachs Abschiedsgeschenk, die «abgesicherte» elektronische Patientenakte (ePA) ist völlig überraschenderweise direkt nach dem Bundesstart erneut gehackt worden. Norbert Häring kommentiert angesichts der Datenlecks, wer die ePA nicht abwähle, könne seine Gesundheitsdaten ebensogut auf Facebook posten.
Dass die staatlichen Kontrolleure so wenig auf freie Software und dezentrale Lösungen setzen, verdeutlicht die eigentlichen Intentionen hinter der Digitalisierungswut. Um Sicherheit und Souveränität geht es ihnen jedenfalls nicht – sonst gäbe es zum Beispiel mehr Unterstützung für Bitcoin und für Initiativen wie die der Spar-Supermärkte in der Schweiz.

2025-04-25 20:06:24Die Wahrheit verletzt tiefer als jede Beleidigung. \ Marquis de Sade
Sagen Sie niemals «Terroristin B.», «Schwachkopf H.», «korrupter Drecksack S.» oder «Meinungsfreiheitshasserin F.» und verkneifen Sie sich Memes, denn so etwas könnte Ihnen als Beleidigung oder Verleumdung ausgelegt werden und rechtliche Konsequenzen haben. Auch mit einer Frau M.-A. S.-Z. ist in dieser Beziehung nicht zu spaßen, sie gehört zu den Top-Anzeigenstellern.
«Politikerbeleidigung» als Straftatbestand wurde 2021 im Kampf gegen «Rechtsextremismus und Hasskriminalität» in Deutschland eingeführt, damals noch unter der Regierung Merkel. Im Gesetz nicht festgehalten ist die Unterscheidung zwischen schlechter Hetze und guter Hetze – trotzdem ist das gängige Praxis, wie der Titel fast schon nahelegt.
So dürfen Sie als Politikerin heute den Tesla als «Nazi-Auto» bezeichnen und dies ausdrücklich auf den Firmengründer Elon Musk und dessen «rechtsextreme Positionen» beziehen, welche Sie nicht einmal belegen müssen. [1] Vielleicht ernten Sie Proteste, jedoch vorrangig wegen der «gut bezahlten, unbefristeten Arbeitsplätze» in Brandenburg. Ihren Tweet hat die Berliner Senatorin Cansel Kiziltepe inzwischen offenbar dennoch gelöscht.
Dass es um die Meinungs- und Pressefreiheit in der Bundesrepublik nicht mehr allzu gut bestellt ist, befürchtet man inzwischen auch schon im Ausland. Der Fall des Journalisten David Bendels, der kürzlich wegen eines Faeser-Memes zu sieben Monaten Haft auf Bewährung verurteilt wurde, führte in diversen Medien zu Empörung. Die Welt versteckte ihre Kritik mit dem Titel «Ein Urteil wie aus einer Diktatur» hinter einer Bezahlschranke.
Unschöne, heutzutage vielleicht strafbare Kommentare würden mir auch zu einigen anderen Themen und Akteuren einfallen. Ein Kandidat wäre der deutsche Bundesgesundheitsminister (ja, er ist es tatsächlich immer noch). Während sich in den USA auf dem Gebiet etwas bewegt und zum Beispiel Robert F. Kennedy Jr. will, dass die Gesundheitsbehörde (CDC) keine Covid-Impfungen für Kinder mehr empfiehlt, möchte Karl Lauterbach vor allem das Corona-Lügengebäude vor dem Einsturz bewahren.
«Ich habe nie geglaubt, dass die Impfungen nebenwirkungsfrei sind», sagte Lauterbach jüngst der ZDF-Journalistin Sarah Tacke. Das steht in krassem Widerspruch zu seiner früher verbreiteten Behauptung, die Gen-Injektionen hätten keine Nebenwirkungen. Damit entlarvt er sich selbst als Lügner. Die Bezeichnung ist absolut berechtigt, dieser Mann dürfte keinerlei politische Verantwortung tragen und das Verhalten verlangt nach einer rechtlichen Überprüfung. Leider ist ja die Justiz anderweitig beschäftigt und hat außerdem selbst keine weiße Weste.
Obendrein kämpfte der Herr Minister für eine allgemeine Impfpflicht. Er beschwor dabei das Schließen einer «Impflücke», wie es die Weltgesundheitsorganisation – die «wegen Trump» in finanziellen Schwierigkeiten steckt – bis heute tut. Die WHO lässt aktuell ihre «Europäische Impfwoche» propagieren, bei der interessanterweise von Covid nicht mehr groß die Rede ist.
Einen «Klima-Leugner» würden manche wohl Nir Shaviv nennen, das ist ja nicht strafbar. Der Astrophysiker weist nämlich die Behauptung von einer Klimakrise zurück. Gemäß seiner Forschung ist mindestens die Hälfte der Erderwärmung nicht auf menschliche Emissionen, sondern auf Veränderungen im Sonnenverhalten zurückzuführen.
Das passt vielleicht auch den «Klima-Hysterikern» der britischen Regierung ins Konzept, die gerade Experimente zur Verdunkelung der Sonne angekündigt haben. Produzenten von Kunstfleisch oder Betreiber von Insektenfarmen würden dagegen vermutlich die Geschichte vom fatalen CO2 bevorzugen. Ihnen würde es besser passen, wenn der verantwortungsvolle Erdenbürger sein Verhalten gründlich ändern müsste.
In unserer völlig verkehrten Welt, in der praktisch jede Verlautbarung außerhalb der abgesegneten Narrative potenziell strafbar sein kann, gehört fast schon Mut dazu, Dinge offen anzusprechen. Im «besten Deutschland aller Zeiten» glaubten letztes Jahr nur noch 40 Prozent der Menschen, ihre Meinung frei äußern zu können. Das ist ein Armutszeugnis, und es sieht nicht gerade nach Besserung aus. Umso wichtiger ist es, dagegen anzugehen.

2025-02-03 22:25:35Last week, in a bid to understand the LLM hype, I decided to write a trivial nostr-related program in rust via a combination of codebuff (yes, that is a referral link, pls click), aider, and goose.
The result of the experiment was inconclusive, but as a side effect it produced a great case study in converting a NINO into a Real Nostr App.
Introducing Roz
Roz, a friendly notary for nostr events.
To use it, simply publish an event to
relay.damus.io
ornos.lol
, and roz will make note of it. To find out when roz first saw a given event, just ask:curl https://roz.coracle.social/notary/cb429632ae22557d677a11149b2d0ccd72a1cf66ac55da30e3534ed1a492765d
This will return a JSON payload with a
seen
key indicating when roz first saw the event. How (and whether) you use this is up to you!De-NINO-fying roz
Roz is just a proof of concept, so don't rely on it being there forever. And anyway, roz is a NINO, since it provides value to nostr (potentially), but doesn't really do things in a nostr-native way. It also hard-codes its relays, and certainly doesn't use the outbox model or sign events. But that's ok, it's a proof of concept.
A much better way to do this would be to modify roz to properly leverage nostr's capabilities, namely:
- Use nostr-native data formats (i.e., draft a new kind)
- Use relays instead of proprietary servers for data storage
- Leverage nostr identities and signatures to decouple trust from storage, and allow trusted attestations to be discovered
Luckily, this is not hard at all. In fact, I've gone ahead and drafted a PR to the NIPs repo that adds timestamp annotations to NIP 03, as an alternative to OpenTimestamps. The trade-off is that while user attestations are far less reliable than OTS proofs, they're much easier to verify, and can reach a pretty high level of reliability by combining multiple attestation sources with other forms of reputation.
In other words, instead of going nuclear and embedding your attestations into The Time Chain, you can simply ask 5-10 relays or people you trust for their attestations for a given event.
This PR isn't terribly important on its own, but it does remove one small barrier between us and trusted key rotation events (or other types of event that require establishing a verifiable chain of causality).

2025-04-20 19:54:32Es ist völlig unbestritten, dass der Angriff der russischen Armee auf die Ukraine im Februar 2022 strikt zu verurteilen ist. Ebenso unbestritten ist Russland unter Wladimir Putin keine brillante Demokratie. Aus diesen Tatsachen lässt sich jedoch nicht das finstere Bild des russischen Präsidenten – und erst recht nicht des Landes – begründen, das uns durchweg vorgesetzt wird und den Kern des aktuellen europäischen Bedrohungs-Szenarios darstellt. Da müssen wir schon etwas genauer hinschauen.
Der vorliegende Artikel versucht derweil nicht, den Einsatz von Gewalt oder die Verletzung von Menschenrechten zu rechtfertigen oder zu entschuldigen – ganz im Gegenteil. Dass jedoch der Verdacht des «Putinverstehers» sofort latent im Raume steht, verdeutlicht, was beim Thema «Russland» passiert: Meinungsmache und Manipulation.
Angesichts der mentalen Mobilmachung seitens Politik und Medien sowie des Bestrebens, einen bevorstehenden Krieg mit Russland geradezu herbeizureden, ist es notwendig, dieser fatalen Entwicklung entgegenzutreten. Wenn wir uns nur ein wenig von der herrschenden Schwarz-Weiß-Malerei freimachen, tauchen automatisch Fragen auf, die Risse im offiziellen Narrativ enthüllen. Grund genug, nachzuhaken.
Wer sich schon länger auch abseits der Staats- und sogenannten Leitmedien informiert, der wird in diesem Artikel vermutlich nicht viel Neues erfahren. Andere könnten hier ein paar unbekannte oder vergessene Aspekte entdecken. Möglicherweise klärt sich in diesem Kontext die Wahrnehmung der aktuellen (unserer eigenen!) Situation ein wenig.
Manipulation erkennen
Corona-«Pandemie», menschengemachter Klimawandel oder auch Ukraine-Krieg: Jede Menge Krisen, und für alle gibt es ein offizielles Narrativ, dessen Hinterfragung unerwünscht ist. Nun ist aber ein Narrativ einfach eine Erzählung, eine Geschichte (Latein: «narratio») und kein Tatsachenbericht. Und so wie ein Märchen soll auch das Narrativ eine Botschaft vermitteln.
Über die Methoden der Manipulation ist viel geschrieben worden, sowohl in Bezug auf das Individuum als auch auf die Massen. Sehr wertvolle Tipps dazu, wie man Manipulationen durchschauen kann, gibt ein Büchlein [1] von Albrecht Müller, dem Herausgeber der NachDenkSeiten.
Die Sprache selber eignet sich perfekt für die Manipulation. Beispielsweise kann die Wortwahl Bewertungen mitschwingen lassen, regelmäßiges Wiederholen (gerne auch von verschiedenen Seiten) lässt Dinge irgendwann «wahr» erscheinen, Übertreibungen fallen auf und hinterlassen wenigstens eine Spur im Gedächtnis, genauso wie Andeutungen. Belege spielen dabei keine Rolle.
Es gibt auffällig viele Sprachregelungen, die offenbar irgendwo getroffen und irgendwie koordiniert werden. Oder alle Redenschreiber und alle Medien kopieren sich neuerdings permanent gegenseitig. Welchen Zweck hat es wohl, wenn der Krieg in der Ukraine durchgängig und quasi wörtlich als «russischer Angriffskrieg auf die Ukraine» bezeichnet wird? Obwohl das in der Sache richtig ist, deutet die Art der Verwendung auf gezielte Beeinflussung hin und soll vor allem das Feindbild zementieren.
Sprachregelungen dienen oft der Absicherung einer einseitigen Darstellung. Das Gleiche gilt für das Verkürzen von Informationen bis hin zum hartnäckigen Verschweigen ganzer Themenbereiche. Auch hierfür gibt es rund um den Ukraine-Konflikt viele gute Beispiele.
Das gewünschte Ergebnis solcher Methoden ist eine Schwarz-Weiß-Malerei, bei der einer eindeutig als «der Böse» markiert ist und die anderen automatisch «die Guten» sind. Das ist praktisch und demonstriert gleichzeitig ein weiteres Manipulationswerkzeug: die Verwendung von Doppelstandards. Wenn man es schafft, bei wichtigen Themen regelmäßig mit zweierlei Maß zu messen, ohne dass das Publikum protestiert, dann hat man freie Bahn.
Experten zu bemühen, um bestimmte Sachverhalte zu erläutern, ist sicher sinnvoll, kann aber ebenso missbraucht werden, schon allein durch die Auswahl der jeweiligen Spezialisten. Seit «Corona» werden viele erfahrene und ehemals hoch angesehene Fachleute wegen der «falschen Meinung» diffamiert und gecancelt. [2] Das ist nicht nur ein brutaler Umgang mit Menschen, sondern auch eine extreme Form, die öffentliche Meinung zu steuern.
Wann immer wir also erkennen (weil wir aufmerksam waren), dass wir bei einem bestimmten Thema manipuliert werden, dann sind zwei logische und notwendige Fragen: Warum? Und was ist denn richtig? In unserem Russland-Kontext haben die Antworten darauf viel mit Geopolitik und Geschichte zu tun.
Ist Russland aggressiv und expansiv?
Angeblich plant Russland, europäische NATO-Staaten anzugreifen, nach dem Motto: «Zuerst die Ukraine, dann den Rest». In Deutschland weiß man dafür sogar das Datum: «Wir müssen bis 2029 kriegstüchtig sein», versichert Verteidigungsminister Pistorius.
Historisch gesehen ist es allerdings eher umgekehrt: Russland, bzw. die Sowjetunion, ist bereits dreimal von Westeuropa aus militärisch angegriffen worden. Die Feldzüge Napoleons, des deutschen Kaiserreichs und Nazi-Deutschlands haben Millionen Menschen das Leben gekostet. Bei dem ausdrücklichen Vernichtungskrieg ab 1941 kam es außerdem zu Brutalitäten wie der zweieinhalbjährigen Belagerung Leningrads (heute St. Petersburg) durch Hitlers Wehrmacht. Deren Ziel, die Bevölkerung auszuhungern, wurde erreicht: über eine Million tote Zivilisten.
Trotz dieser Erfahrungen stimmte Michail Gorbatschow 1990 der deutschen Wiedervereinigung zu und die Sowjetunion zog ihre Truppen aus Osteuropa zurück (vgl. Abb. 1). Der Warschauer Pakt wurde aufgelöst, der Kalte Krieg formell beendet. Die Sowjets erhielten damals von führenden westlichen Politikern die Zusicherung, dass sich die NATO «keinen Zentimeter ostwärts» ausdehnen würde, das ist dokumentiert. [3]
Expandiert ist die NATO trotzdem, und zwar bis an Russlands Grenzen (vgl. Abb. 2). Laut dem Politikberater Jeffrey Sachs handelt es sich dabei um ein langfristiges US-Projekt, das von Anfang an die Ukraine und Georgien mit einschloss. Offiziell wurde der Beitritt beiden Staaten 2008 angeboten. In jedem Fall könnte die massive Ost-Erweiterung seit 1999 aus russischer Sicht nicht nur als Vertrauensbruch, sondern durchaus auch als aggressiv betrachtet werden.
Russland hat den europäischen Staaten mehrfach die Hand ausgestreckt [4] für ein friedliches Zusammenleben und den «Aufbau des europäischen Hauses». Präsident Putin sei «in seiner ersten Amtszeit eine Chance für Europa» gewesen, urteilt die Journalistin und langjährige Russland-Korrespondentin der ARD, Gabriele Krone-Schmalz. Er habe damals viele positive Signale Richtung Westen gesendet.
Die Europäer jedoch waren scheinbar an einer Partnerschaft mit dem kontinentalen Nachbarn weniger interessiert als an der mit dem transatlantischen Hegemon. Sie verkennen bis heute, dass eine gedeihliche Zusammenarbeit in Eurasien eine Gefahr für die USA und deren bekundetes Bestreben ist, die «einzige Weltmacht» zu sein – «Full Spectrum Dominance» [5] nannte das Pentagon das. Statt einem neuen Kalten Krieg entgegenzuarbeiten, ließen sich europäische Staaten selber in völkerrechtswidrige «US-dominierte Angriffskriege» [6] verwickeln, wie in Serbien, Afghanistan, dem Irak, Libyen oder Syrien. Diese werden aber selten so benannt.
Speziell den Deutschen stünde außer einer Portion Realismus auch etwas mehr Dankbarkeit gut zu Gesicht. Das Geschichtsbewusstsein der Mehrheit scheint doch recht selektiv und das Selbstbewusstsein einiger etwas desorientiert zu sein. Bekanntermaßen waren es die Soldaten der sowjetischen Roten Armee, die unter hohen Opfern 1945 Deutschland «vom Faschismus befreit» haben. Bei den Gedenkfeiern zu 80 Jahren Kriegsende will jedoch das Auswärtige Amt – noch unter der Diplomatie-Expertin Baerbock, die sich schon länger offiziell im Krieg mit Russland wähnt, – nun keine Russen sehen: Sie sollen notfalls rausgeschmissen werden.
«Die Grundsatzfrage lautet: Geht es Russland um einen angemessenen Platz in einer globalen Sicherheitsarchitektur, oder ist Moskau schon seit langem auf einem imperialistischen Trip, der befürchten lassen muss, dass die Russen in fünf Jahren in Berlin stehen?»
So bringt Gabriele Krone-Schmalz [7] die eigentliche Frage auf den Punkt, die zur Einschätzung der Situation letztlich auch jeder für sich beantworten muss.
Was ist los in der Ukraine?
In der internationalen Politik geht es nie um Demokratie oder Menschenrechte, sondern immer um Interessen von Staaten. Diese These stammt von Egon Bahr, einem der Architekten der deutschen Ostpolitik des «Wandels durch Annäherung» aus den 1960er und 70er Jahren. Sie trifft auch auf den Ukraine-Konflikt zu, den handfeste geostrategische und wirtschaftliche Interessen beherrschen, obwohl dort angeblich «unsere Demokratie» verteidigt wird.
Es ist ein wesentliches Element des Ukraine-Narrativs und Teil der Manipulation, die Vorgeschichte des Krieges wegzulassen – mindestens die vor der russischen «Annexion» der Halbinsel Krim im März 2014, aber oft sogar komplett diejenige vor der Invasion Ende Februar 2022. Das Thema ist komplex, aber einige Aspekte, die für eine Beurteilung nicht unwichtig sind, will ich wenigstens kurz skizzieren. [8]
Das Gebiet der heutigen Ukraine und Russlands – die übrigens in der «Kiewer Rus» gemeinsame Wurzeln haben – hat der britische Geostratege Halford Mackinder bereits 1904 als eurasisches «Heartland» bezeichnet, dessen Kontrolle er eine große Bedeutung für die imperiale Strategie Großbritanniens zumaß. Für den ehemaligen Sicherheits- und außenpolitischen Berater mehrerer US-amerikanischer Präsidenten und Mitgründer der Trilateralen Kommission, Zbigniew Brzezinski, war die Ukraine nach der Auflösung der Sowjetunion ein wichtiger Spielstein auf dem «eurasischen Schachbrett», wegen seiner Nähe zu Russland, seiner Bodenschätze und seines Zugangs zum Schwarzen Meer.
Die Ukraine ist seit langem ein gespaltenes Land. Historisch zerrissen als Spielball externer Interessen und geprägt von ethnischen, kulturellen, religiösen und geografischen Unterschieden existiert bis heute, grob gesagt, eine Ost-West-Spaltung, welche die Suche nach einer nationalen Identität stark erschwert.
Insbesondere im Zuge der beiden Weltkriege sowie der Russischen Revolution entstanden tiefe Risse in der Bevölkerung. Ukrainer kämpften gegen Ukrainer, zum Beispiel die einen auf der Seite von Hitlers faschistischer Nazi-Armee und die anderen auf der von Stalins kommunistischer Roter Armee. Die Verbrechen auf beiden Seiten sind nicht vergessen. Dass nach der Unabhängigkeit 1991 versucht wurde, Figuren wie den radikalen Nationalisten Symon Petljura oder den Faschisten und Nazi-Kollaborateur Stepan Bandera als «Nationalhelden» zu installieren, verbessert die Sache nicht.
Während die USA und EU-Staaten zunehmend «ausländische Einmischung» (speziell russische) in «ihre Demokratien» wittern, betreiben sie genau dies seit Jahrzehnten in vielen Ländern der Welt. Die seit den 2000er Jahren bekannten «Farbrevolutionen» in Osteuropa werden oft als Methode des Regierungsumsturzes durch von außen gesteuerte «demokratische» Volksaufstände beschrieben. Diese Strategie geht auf Analysen zum «Schwarmverhalten» [9] seit den 1960er Jahren zurück (Studentenproteste), wo es um die potenzielle Wirksamkeit einer «rebellischen Hysterie» von Jugendlichen bei postmodernen Staatsstreichen geht. Heute nennt sich dieses gezielte Kanalisieren der Massen zur Beseitigung unkooperativer Regierungen «Soft-Power».
In der Ukraine gab es mit der «Orangen Revolution» 2004 und dem «Euromaidan» 2014 gleich zwei solcher «Aufstände». Der erste erzwang wegen angeblicher Unregelmäßigkeiten eine Wiederholung der Wahlen, was mit Wiktor Juschtschenko als neuem Präsidenten endete. Dieser war ehemaliger Direktor der Nationalbank und Befürworter einer Annäherung an EU und NATO. Seine Frau, die First Lady, ist US-amerikanische «Philanthropin» und war Beamtin im Weißen Haus in der Reagan- und der Bush-Administration.
Im Gegensatz zu diesem ersten Event endete der sogenannte Euromaidan unfriedlich und blutig. Die mehrwöchigen Proteste gegen Präsident Wiktor Janukowitsch, in Teilen wegen des nicht unterzeichneten Assoziierungsabkommens mit der EU, wurden zunehmend gewalttätiger und von Nationalisten und Faschisten des «Rechten Sektors» dominiert. Sie mündeten Ende Februar 2014 auf dem Kiewer Unabhängigkeitsplatz (Maidan) in einem Massaker durch Scharfschützen. Dass deren Herkunft und die genauen Umstände nicht geklärt wurden, störte die Medien nur wenig. [10]
Janukowitsch musste fliehen, er trat nicht zurück. Vielmehr handelte es sich um einen gewaltsamen, allem Anschein nach vom Westen inszenierten Putsch. Laut Jeffrey Sachs war das kein Geheimnis, außer vielleicht für die Bürger. Die USA unterstützten die Post-Maidan-Regierung nicht nur, sie beeinflussten auch ihre Bildung. Das geht unter anderem aus dem berühmten «Fuck the EU»-Telefonat der US-Chefdiplomatin für die Ukraine, Victoria Nuland, mit Botschafter Geoffrey Pyatt hervor.
Dieser Bruch der demokratischen Verfassung war letztlich der Auslöser für die anschließenden Krisen auf der Krim und im Donbass (Ostukraine). Angesichts der ukrainischen Geschichte mussten die nationalistischen Tendenzen und die Beteiligung der rechten Gruppen an dem Umsturz bei der russigsprachigen Bevölkerung im Osten ungute Gefühle auslösen. Es gab Kritik an der Übergangsregierung, Befürworter einer Abspaltung und auch für einen Anschluss an Russland.
Ebenso konnte Wladimir Putin in dieser Situation durchaus Bedenken wegen des Status der russischen Militärbasis für seine Schwarzmeerflotte in Sewastopol auf der Krim haben, für die es einen langfristigen Pachtvertrag mit der Ukraine gab. Was im März 2014 auf der Krim stattfand, sei keine Annexion, sondern eine Abspaltung (Sezession) nach einem Referendum gewesen, also keine gewaltsame Aneignung, urteilte der Rechtswissenschaftler Reinhard Merkel in der FAZ sehr detailliert begründet. Übrigens hatte die Krim bereits zu Zeiten der Sowjetunion den Status einer autonomen Republik innerhalb der Ukrainischen SSR.
Anfang April 2014 wurden in der Ostukraine die «Volksrepubliken» Donezk und Lugansk ausgerufen. Die Kiewer Übergangsregierung ging unter der Bezeichnung «Anti-Terror-Operation» (ATO) militärisch gegen diesen, auch von Russland instrumentalisierten Widerstand vor. Zufällig war kurz zuvor CIA-Chef John Brennan in Kiew. Die Maßnahmen gingen unter dem seit Mai neuen ukrainischen Präsidenten, dem Milliardär Petro Poroschenko, weiter. Auch Wolodymyr Selenskyj beendete den Bürgerkrieg nicht, als er 2019 vom Präsidenten-Schauspieler, der Oligarchen entmachtet, zum Präsidenten wurde. Er fuhr fort, die eigene Bevölkerung zu bombardieren.
Mit dem Einmarsch russischer Truppen in die Ostukraine am 24. Februar 2022 begann die zweite Phase des Krieges. Die Wochen und Monate davor waren intensiv. Im November hatte die Ukraine mit den USA ein Abkommen über eine «strategische Partnerschaft» unterzeichnet. Darin sagten die Amerikaner ihre Unterstützung der EU- und NATO-Perspektive der Ukraine sowie quasi für die Rückeroberung der Krim zu. Dagegen ließ Putin der NATO und den USA im Dezember 2021 einen Vertragsentwurf über beiderseitige verbindliche Sicherheitsgarantien zukommen, den die NATO im Januar ablehnte. Im Februar eskalierte laut OSZE die Gewalt im Donbass.
Bereits wenige Wochen nach der Invasion, Ende März 2022, kam es in Istanbul zu Friedensverhandlungen, die fast zu einer Lösung geführt hätten. Dass der Krieg nicht damals bereits beendet wurde, lag daran, dass der Westen dies nicht wollte. Man war der Meinung, Russland durch die Ukraine in diesem Stellvertreterkrieg auf Dauer militärisch schwächen zu können. Angesichts von Hunderttausenden Toten, Verletzten und Traumatisierten, die als Folge seitdem zu beklagen sind, sowie dem Ausmaß der Zerstörung, fehlen einem die Worte.
Hasst der Westen die Russen?
Diese Frage drängt sich auf, wenn man das oft unerträglich feindselige Gebaren beobachtet, das beileibe nicht neu ist und vor Doppelmoral trieft. Russland und speziell die Person Wladimir Putins werden regelrecht dämonisiert, was gleichzeitig scheinbar jede Form von Diplomatie ausschließt.
Russlands militärische Stärke, seine geografische Lage, sein Rohstoffreichtum oder seine unabhängige diplomatische Tradition sind sicher Störfaktoren für das US-amerikanische Bestreben, der Boss in einer unipolaren Welt zu sein. Ein womöglich funktionierender eurasischer Kontinent, insbesondere gute Beziehungen zwischen Russland und Deutschland, war indes schon vor dem Ersten Weltkrieg eine Sorge des britischen Imperiums.
Ein «Vergehen» von Präsident Putin könnte gewesen sein, dass er die neoliberale Schocktherapie à la IWF und den Ausverkauf des Landes (auch an US-Konzerne) beendete, der unter seinem Vorgänger herrschte. Dabei zeigte er sich als Führungspersönlichkeit und als nicht so formbar wie Jelzin. Diese Aspekte allein sind aber heute vermutlich keine ausreichende Erklärung für ein derart gepflegtes Feindbild.
Der Historiker und Philosoph Hauke Ritz erweitert den Fokus der Fragestellung zu: «Warum hasst der Westen die Russen so sehr?», was er zum Beispiel mit dem Medienforscher Michael Meyen und mit der Politikwissenschaftlerin Ulrike Guérot bespricht. Ritz stellt die interessante These [11] auf, dass Russland eine Provokation für den Westen sei, welcher vor allem dessen kulturelles und intellektuelles Potenzial fürchte.
Die Russen sind Europäer aber anders, sagt Ritz. Diese «Fremdheit in der Ähnlichkeit» erzeuge vielleicht tiefe Ablehnungsgefühle. Obwohl Russlands Identität in der europäischen Kultur verwurzelt ist, verbinde es sich immer mit der Opposition in Europa. Als Beispiele nennt er die Kritik an der katholischen Kirche oder die Verbindung mit der Arbeiterbewegung. Christen, aber orthodox; Sozialismus statt Liberalismus. Das mache das Land zum Antagonisten des Westens und zu einer Bedrohung der Machtstrukturen in Europa.
Fazit
Selbstverständlich kann man Geschichte, Ereignisse und Entwicklungen immer auf verschiedene Arten lesen. Dieser Artikel, obwohl viel zu lang, konnte nur einige Aspekte der Ukraine-Tragödie anreißen, die in den offiziellen Darstellungen in der Regel nicht vorkommen. Mindestens dürfte damit jedoch klar geworden sein, dass die Russische Föderation bzw. Wladimir Putin nicht der alleinige Aggressor in diesem Konflikt ist. Das ist ein Stellvertreterkrieg zwischen USA/NATO (gut) und Russland (böse); die Ukraine (edel) wird dabei schlicht verheizt.
Das ist insofern von Bedeutung, als die gesamte europäische Kriegshysterie auf sorgsam kultivierten Freund-Feind-Bildern beruht. Nur so kann Konfrontation und Eskalation betrieben werden, denn damit werden die wahren Hintergründe und Motive verschleiert. Angst und Propaganda sind notwendig, damit die Menschen den Wahnsinn mitmachen. Sie werden belogen, um sie zuerst zu schröpfen und anschließend auf die Schlachtbank zu schicken. Das kann niemand wollen, außer den stets gleichen Profiteuren: die Rüstungs-Lobby und die großen Investoren, die schon immer an Zerstörung und Wiederaufbau verdient haben.
Apropos Investoren: Zu den Top-Verdienern und somit Hauptinteressenten an einer Fortführung des Krieges zählt BlackRock, einer der weltgrößten Vermögensverwalter. Der deutsche Bundeskanzler in spe, Friedrich Merz, der gerne «Taurus»-Marschflugkörper an die Ukraine liefern und die Krim-Brücke zerstören möchte, war von 2016 bis 2020 Aufsichtsratsvorsitzender von BlackRock in Deutschland. Aber das hat natürlich nichts zu sagen, der Mann macht nur seinen Job.
Es ist ein Spiel der Kräfte, es geht um Macht und strategische Kontrolle, um Geheimdienste und die Kontrolle der öffentlichen Meinung, um Bodenschätze, Rohstoffe, Pipelines und Märkte. Das klingt aber nicht sexy, «Demokratie und Menschenrechte» hört sich besser und einfacher an. Dabei wäre eine für alle Seiten förderliche Politik auch nicht so kompliziert; das Handwerkszeug dazu nennt sich Diplomatie. Noch einmal Gabriele Krone-Schmalz:
«Friedliche Politik ist nichts anderes als funktionierender Interessenausgleich. Da geht’s nicht um Moral.»
Die Situation in der Ukraine ist sicher komplex, vor allem wegen der inneren Zerrissenheit. Es dürfte nicht leicht sein, eine friedliche Lösung für das Zusammenleben zu finden, aber die Beteiligten müssen es vor allem wollen. Unter den gegebenen Umständen könnte eine sinnvolle Perspektive mit Neutralität und föderalen Strukturen zu tun haben.
Allen, die sich bis hierher durch die Lektüre gearbeitet (oder auch einfach nur runtergescrollt) haben, wünsche ich frohe Oster-Friedenstage!

2025-01-29 05:55:02The land that belongs to the indigenous peoples of Russia has been seized by a gang of killers who have unleashed a war of extermination. They wipe out anyone who refuses to conform to their rules. Those who disagree and stay behind are tortured and killed in prisons and labor camps. Those who flee lose their homeland, dissolve into foreign cultures, and fade away. And those who stand up to protect their people are attacked by the misled and deceived. The deceived die for the unchecked greed of a single dictator—thousands from both sides, people who just wanted to live, raise their kids, and build a future.
Now, they are forced to make an impossible choice: abandon their homeland or die. Some perish on the battlefield, others lose themselves in exile, stripped of their identity, scattered in a world that isn’t theirs.
There’s been endless debate about how to fix this, how to clear the field of the weeds that choke out every new sprout, every attempt at change. But the real problem? We can’t play by their rules. We can’t speak their language or use their weapons. We stand for humanity, and no matter how righteous our cause, we will not multiply suffering. Victory doesn’t come from matching the enemy—it comes from staying ahead, from using tools they haven’t mastered yet. That’s how wars are won.
Our only resource is the will of the people to rewrite the order of things. Historian Timothy Snyder once said that a nation cannot exist without a city. A city is where the most active part of a nation thrives. But the cities are occupied. The streets are watched. Gatherings are impossible. They control the money. They control the mail. They control the media. And any dissent is crushed before it can take root.
So I started asking myself: How do we stop this fragmentation? How do we create a space where people can rebuild their connections when they’re ready? How do we build a self-sustaining network, where everyone contributes and benefits proportionally, while keeping their freedom to leave intact? And more importantly—how do we make it spread, even in occupied territory?
In 2009, something historic happened: the internet got its own money. Thanks to Satoshi Nakamoto, the world took a massive leap forward. Bitcoin and decentralized ledgers shattered the idea that money must be controlled by the state. Now, to move or store value, all you need is an address and a key. A tiny string of text, easy to carry, impossible to seize.
That was the year money broke free. The state lost its grip. Its biggest weapon—physical currency—became irrelevant. Money became purely digital.
The internet was already a sanctuary for information, a place where people could connect and organize. But with Bitcoin, it evolved. Now, value itself could flow freely, beyond the reach of authorities.
Think about it: when seedlings are grown in controlled environments before being planted outside, they get stronger, survive longer, and bear fruit faster. That’s how we handle crops in harsh climates—nurture them until they’re ready for the wild.
Now, picture the internet as that controlled environment for ideas. Bitcoin? It’s the fertile soil that lets them grow. A testing ground for new models of interaction, where concepts can take root before they move into the real world. If nation-states are a battlefield, locked in a brutal war for territory, the internet is boundless. It can absorb any number of ideas, any number of people, and it doesn’t run out of space.
But for this ecosystem to thrive, people need safe ways to communicate, to share ideas, to build something real—without surveillance, without censorship, without the constant fear of being erased.
This is where Nostr comes in.
Nostr—"Notes and Other Stuff Transmitted by Relays"—is more than just a messaging protocol. It’s a new kind of city. One that no dictator can seize, no corporation can own, no government can shut down.
It’s built on decentralization, encryption, and individual control. Messages don’t pass through central servers—they are relayed through independent nodes, and users choose which ones to trust. There’s no master switch to shut it all down. Every person owns their identity, their data, their connections. And no one—no state, no tech giant, no algorithm—can silence them.
In a world where cities fall and governments fail, Nostr is a city that cannot be occupied. A place for ideas, for networks, for freedom. A city that grows stronger the more people build within it.

2025-01-18 06:09:50Para esse exemplo iremos usar: | Nome | Imagem | Descrição | | --------------- | ------------------------------------------------------------ | ------------------------------------------------------------ | | Raspberry PI B+ |
| Cortex-A53 (ARMv8) 64-bit a 1.4GHz e 1 GB de SDRAM LPDDR2, | | Pen drive |
| 16Gb |
Recomendo que use o Ubuntu Server para essa instalação. Você pode baixar o Ubuntu para Raspberry Pi aqui. O passo a passo para a instalação do Ubuntu no Raspberry Pi está disponível aqui. Não instale um desktop (como xubuntu, lubuntu, xfce, etc.).
Passo 1: Atualizar o Sistema 🖥️
Primeiro, atualize seu sistema e instale o Tor:
bash apt update apt install tor
Passo 2: Criar o Arquivo de Serviço
nrs.service
🔧Crie o arquivo de serviço que vai gerenciar o servidor Nostr. Você pode fazer isso com o seguinte conteúdo:
```unit [Unit] Description=Nostr Relay Server Service After=network.target
[Service] Type=simple WorkingDirectory=/opt/nrs ExecStart=/opt/nrs/nrs-arm64 Restart=on-failure
[Install] WantedBy=multi-user.target ```
Passo 3: Baixar o Binário do Nostr 🚀

Agora, crie as pastas para o aplicativo e o pendrive:
bash mkdir -p /opt/nrs /mnt/edriver
Passo 5: Listar os Dispositivos Conectados 🔌
Para saber qual dispositivo você vai usar, liste todos os dispositivos conectados:
bash lsblk
Passo 6: Formatando o Pendrive 💾
Escolha o pendrive correto (por exemplo,
/dev/sda
) e formate-o:bash mkfs.vfat /dev/sda
Passo 7: Montar o Pendrive 💻
Monte o pendrive na pasta
/mnt/edriver
:bash mount /dev/sda /mnt/edriver
Passo 8: Verificar UUID dos Dispositivos 📋
Para garantir que o sistema monte o pendrive automaticamente, liste os UUID dos dispositivos conectados:
bash blkid
Passo 9: Alterar o
fstab
para Montar o Pendrive Automáticamente 📝Abra o arquivo
/etc/fstab
e adicione uma linha para o pendrive, com o UUID que você obteve no passo anterior. A linha deve ficar assim:fstab UUID=9c9008f8-f852 /mnt/edriver vfat defaults 0 0
Passo 10: Copiar o Binário para a Pasta Correta 📥
Agora, copie o binário baixado para a pasta
/opt/nrs
:bash cp nrs-arm64 /opt/nrs
Passo 11: Criar o Arquivo de Configuração 🛠️
Crie o arquivo de configuração com o seguinte conteúdo e salve-o em
/opt/nrs/config.yaml
:yaml app_env: production info: name: Nostr Relay Server description: Nostr Relay Server pub_key: "" contact: "" url: http://localhost:3334 icon: https://external-content.duckduckgo.com/iu/?u= https://public.bnbstatic.com/image/cms/crawler/COINCU_NEWS/image-495-1024x569.png base_path: /mnt/edriver negentropy: true
Passo 12: Copiar o Serviço para o Diretório de Systemd ⚙️
Agora, copie o arquivo
nrs.service
para o diretório/etc/systemd/system/
:bash cp nrs.service /etc/systemd/system/
Recarregue os serviços e inicie o serviço
nrs
:bash systemctl daemon-reload systemctl enable --now nrs.service
Passo 13: Configurar o Tor 🌐
Abra o arquivo de configuração do Tor
/var/lib/tor/torrc
e adicione a seguinte linha:torrc HiddenServiceDir /var/lib/tor/nostr_server/ HiddenServicePort 80 127.0.0.1:3334
Passo 14: Habilitar e Iniciar o Tor 🧅
Agora, ative e inicie o serviço Tor:
bash systemctl enable --now tor.service
O Tor irá gerar um endereço
.onion
para o seu servidor Nostr. Você pode encontrá-lo no arquivo/var/lib/tor/nostr_server/hostname
.
Observações ⚠️
- Com essa configuração, os dados serão salvos no pendrive, enquanto o binário ficará no cartão SD do Raspberry Pi.
- O endereço
.onion
do seu servidor Nostr será algo como:ws://y3t5t5wgwjif<exemplo>h42zy7ih6iwbyd.onion
.
Agora, seu servidor Nostr deve estar configurado e funcionando com Tor! 🥳

2025-04-18 15:53:07Verstand ohne Gefühl ist unmenschlich; \ Gefühl ohne Verstand ist Dummheit. \ Egon Bahr
Seit Jahren werden wir darauf getrimmt, dass Fakten eigentlich gefühlt seien. Aber nicht alles ist relativ und nicht alles ist nach Belieben interpretierbar. Diese Schokoladenhasen beispielsweise, die an Ostern in unseren Gefilden typisch sind, «ostern» zwar nicht, sondern sie sitzen in der Regel, trotzdem verwandelt sie das nicht in «Sitzhasen».
Nichts soll mehr gelten, außer den immer invasiveren Gesetzen. Die eigenen Traditionen und Wurzeln sind potenziell «pfui», um andere Menschen nicht auszuschließen, aber wir mögen uns toleranterweise an die fremden Symbole und Rituale gewöhnen. Dabei ist es mir prinzipiell völlig egal, ob und wann jemand ein Fastenbrechen feiert, am Karsamstag oder jedem anderen Tag oder nie – aber bitte freiwillig.
Und vor allem: Lasst die Finger von den Kindern! In Bern setzten kürzlich Demonstranten ein Zeichen gegen die zunehmende Verbreitung woker Ideologie im Bildungssystem und forderten ein Ende der sexuellen Indoktrination von Schulkindern.
Wenn es nicht wegen des heiklen Themas Migration oder wegen des Regenbogens ist, dann wegen des Klimas. Im Rahmen der «Netto Null»-Agenda zum Kampf gegen das angeblich teuflische CO2 sollen die Menschen ihre Ernährungsgewohnheiten komplett ändern. Nach dem Willen von Produzenten synthetischer Lebensmittel, wie Bill Gates, sollen wir baldmöglichst praktisch auf Fleisch und alle Milchprodukte wie Milch und Käse verzichten. Ein lukratives Geschäftsmodell, das neben der EU aktuell auch von einem britischen Lobby-Konsortium unterstützt wird.
Sollten alle ideologischen Stricke zu reißen drohen, ist da immer noch «der Putin». Die Unions-Europäer offenbaren sich dabei ständig mehr als Vertreter der Rüstungsindustrie. Allen voran zündelt Deutschland an der Kriegslunte, angeführt von einem scheinbar todesmutigen Kanzlerkandidaten Friedrich Merz. Nach dessen erneuter Aussage, «Taurus»-Marschflugkörper an Kiew liefern zu wollen, hat Russland eindeutig klargestellt, dass man dies als direkte Kriegsbeteiligung werten würde – «mit allen sich daraus ergebenden Konsequenzen für Deutschland».
Wohltuend sind Nachrichten über Aktivitäten, die sich der allgemeinen Kriegstreiberei entgegenstellen oder diese öffentlich hinterfragen. Dazu zählt auch ein Kongress kritischer Psychologen und Psychotherapeuten, der letzte Woche in Berlin stattfand. Die vielen Vorträge im Kontext von «Krieg und Frieden» deckten ein breites Themenspektrum ab, darunter Friedensarbeit oder die Notwendigkeit einer «Pädagogik der Kriegsuntüchtigkeit».
Der heutige «stille Freitag», an dem Christen des Leidens und Sterbens von Jesus gedenken, ist vielleicht unabhängig von jeder religiösen oder spirituellen Prägung eine passende Einladung zur Reflexion. In der Ruhe liegt die Kraft. In diesem Sinne wünsche ich Ihnen frohe Ostertage!

2025-04-04 18:47:27Zwei mal drei macht vier, \ widewidewitt und drei macht neune, \ ich mach mir die Welt, \ widewide wie sie mir gefällt. \ Pippi Langstrumpf
Egal, ob Koalitionsverhandlungen oder politischer Alltag: Die Kontroversen zwischen theoretisch verschiedenen Parteien verschwinden, wenn es um den Kampf gegen politische Gegner mit Rückenwind geht. Wer den Alteingesessenen die Pfründe ernsthaft streitig machen könnte, gegen den werden nicht nur «Brandmauern» errichtet, sondern der wird notfalls auch strafrechtlich verfolgt. Doppelstandards sind dabei selbstverständlich inklusive.
In Frankreich ist diese Woche Marine Le Pen wegen der Veruntreuung von EU-Geldern von einem Gericht verurteilt worden. Als Teil der Strafe wurde sie für fünf Jahre vom passiven Wahlrecht ausgeschlossen. Obwohl das Urteil nicht rechtskräftig ist – Le Pen kann in Berufung gehen –, haben die Richter das Verbot, bei Wahlen anzutreten, mit sofortiger Wirkung verhängt. Die Vorsitzende des rechtsnationalen Rassemblement National (RN) galt als aussichtsreiche Kandidatin für die Präsidentschaftswahl 2027.
Das ist in diesem Jahr bereits der zweite gravierende Fall von Wahlbeeinflussung durch die Justiz in einem EU-Staat. In Rumänien hatte Călin Georgescu im November die erste Runde der Präsidentenwahl überraschend gewonnen. Das Ergebnis wurde später annulliert, die behauptete «russische Wahlmanipulation» konnte jedoch nicht bewiesen werden. Die Kandidatur für die Wahlwiederholung im Mai wurde Georgescu kürzlich durch das Verfassungsgericht untersagt.
Die Veruntreuung öffentlicher Gelder muss untersucht und geahndet werden, das steht außer Frage. Diese Anforderung darf nicht selektiv angewendet werden. Hingegen mussten wir in der Vergangenheit bei ungleich schwerwiegenderen Fällen von (mutmaßlichem) Missbrauch ganz andere Vorgehensweisen erleben, etwa im Fall der heutigen EZB-Chefin Christine Lagarde oder im «Pfizergate»-Skandal um die Präsidentin der EU-Kommission Ursula von der Leyen.
Wenngleich derartige Angelegenheiten formal auf einer rechtsstaatlichen Grundlage beruhen mögen, so bleibt ein bitterer Beigeschmack. Es stellt sich die Frage, ob und inwieweit die Justiz politisch instrumentalisiert wird. Dies ist umso interessanter, als die Gewaltenteilung einen essenziellen Teil jeder demokratischen Ordnung darstellt, während die Bekämpfung des politischen Gegners mit juristischen Mitteln gerade bei den am lautesten rufenden Verteidigern «unserer Demokratie» populär zu sein scheint.
Die Delegationen von CDU/CSU und SPD haben bei ihren Verhandlungen über eine Regierungskoalition genau solche Maßnahmen diskutiert. «Im Namen der Wahrheit und der Demokratie» möchte man noch härter gegen «Desinformation» vorgehen und dafür zum Beispiel den Digital Services Act der EU erweitern. Auch soll der Tatbestand der Volksverhetzung verschärft werden – und im Entzug des passiven Wahlrechts münden können. Auf europäischer Ebene würde Friedrich Merz wohl gerne Ungarn das Stimmrecht entziehen.
Der Pegel an Unzufriedenheit und Frustration wächst in großen Teilen der Bevölkerung kontinuierlich. Arroganz, Machtmissbrauch und immer abstrusere Ausreden für offensichtlich willkürliche Maßnahmen werden kaum verhindern, dass den etablierten Parteien die Unterstützung entschwindet. In Deutschland sind die Umfrageergebnisse der AfD ein guter Gradmesser dafür.

- Nostr is an open and interoperable protocol
- You can integrate it with workflow automation tools to augment your experience
- n8n is a great low/no-code workflow automation tool which you can host yourself
- Nostrobots allows you to integrate Nostr into n8n
- In this blog I create some workflow automations for Nostr
- A simple form to delegate posting notes
- Push notifications for mentions on multiple accounts
- Push notifications for your favourite accounts when they post a note
- All workflows are provided as open source with MIT license for you to use
Inter-op All The Things
Nostr is a new open social protocol for the internet. This open nature exciting because of the opportunities for interoperability with other technologies. In Using NFC Cards with Nostr I explored the
nostr:
URI to launch Nostr clients from a card tap.The interoperability of Nostr doesn't stop there. The internet has many super-powers, and Nostr is open to all of them. Simply, there's no one to stop it. There is no one in charge, there are no permissioned APIs, and there are no risks of being de-platformed. If you can imagine technologies that would work well with Nostr, then any and all of them can ride on or alongside Nostr rails.
My mental model for why this is special is Google Wave ~2010. Google Wave was to be the next big platform. Lars was running it and had a big track record from Maps. I was excited for it. Then, Google pulled the plug. And, immediately all the time and capital invested in understanding and building on the platform was wasted.
This cannot happen to Nostr, as there is no one to pull the plug, and maybe even no plug to pull.
So long as users demand Nostr, Nostr will exist, and that is a pretty strong guarantee. It makes it worthwhile to invest in bringing Nostr into our other applications.
All we need are simple ways to plug things together.
Nostr and Workflow Automation
Workflow automation is about helping people to streamline their work. As a user, the most common way I achieve this is by connecting disparate systems together. By setting up one system to trigger another or to move data between systems, I can solve for many different problems and become way more effective.
n8n for workflow automation
Many workflow automation tools exist. My favourite is n8n. n8n is a low/no-code workflow automation platform which allows you to build all kinds of workflows. You can use it for free, you can self-host it, it has a user-friendly UI and useful API. Vs Zapier it can be far more elaborate. Vs Make.com I find it to be more intuitive in how it abstracts away the right parts of the code, but still allows you to code when you need to.
Most importantly you can plug anything into n8n: You have built-in nodes for specific applications. HTTP nodes for any other API-based service. And community nodes built by individual community members for any other purpose you can imagine.
Eating my own dogfood
It's very clear to me that there is a big design space here just demanding to be explored. If you could integrate Nostr with anything, what would you do?
In my view the best way for anyone to start anything is by solving their own problem first (aka "scratching your own itch" and "eating your own dogfood"). As I get deeper into Nostr I find myself controlling multiple Npubs – to date I have a personal Npub, a brand Npub for a community I am helping, an AI assistant Npub, and various testing Npubs. I need ways to delegate access to those Npubs without handing over the keys, ways to know if they're mentioned, and ways to know if they're posting.
I can build workflows with n8n to solve these issues for myself to start with, and keep expanding from there as new needs come up.
Running n8n with Nostrobots
I am mostly non-technical with a very helpful AI. To set up n8n to work with Nostr and operate these workflows should be possible for anyone with basic technology skills.
- I have a cheap VPS which currently runs my HAVEN Nostr Relay and Albyhub Lightning Node in Docker containers,
- My objective was to set up n8n to run alongside these in a separate Docker container on the same server, install the required nodes, and then build and host my workflows.
Installing n8n
Self-hosting n8n could not be easier. I followed n8n's Docker-Compose installation docs–
- Install Docker and Docker-Compose if you haven't already,
- Create your
docker-compose.yml
and.env
files from the docs, - Create your data folder
sudo docker volume create n8n_data
, - Start your container with
sudo docker compose up -d
, - Your n8n instance should be online at port
5678
.
n8n is free to self-host but does require a license. Enter your credentials into n8n to get your free license key. You should now have access to the Workflow dashboard and can create and host any kind of workflows from there.
Installing Nostrobots
To integrate n8n nicely with Nostr, I used the Nostrobots community node by Ocknamo.
In n8n parlance a "node" enables certain functionality as a step in a workflow e.g. a "set" node sets a variable, a "send email" node sends an email. n8n comes with all kinds of "official" nodes installed by default, and Nostr is not amongst them. However, n8n also comes with a framework for community members to create their own "community" nodes, which is where Nostrobots comes in.
You can only use a community node in a self-hosted n8n instance (which is what you have if you are running in Docker on your own server, but this limitation does prevent you from using n8n's own hosted alternative).
To install a community node, see n8n community node docs. From your workflow dashboard–
- Click the "..." in the bottom left corner beside your username, and click "settings",
- Cilck "community nodes" left sidebar,
- Click "Install",
- Enter the "npm Package Name" which is
n8n-nodes-nostrobots
, - Accept the risks and click "Install",
- Nostrobots is now added to your n8n instance.
Using Nostrobots
Nostrobots gives you nodes to help you build Nostr-integrated workflows–
- Nostr Write – for posting Notes to the Nostr network,
- Nostr Read – for reading Notes from the Nostr network, and
- Nostr Utils – for performing certain conversions you may need (e.g. from bech32 to hex).
Nostrobots has good documentation on each node which focuses on simple use cases.
Each node has a "convenience mode" by default. For example, the "Read" Node by default will fetch Kind 1 notes by a simple filter, in Nostrobots parlance a "Strategy". For example, with Strategy set to "Mention" the node will accept a pubkey and fetch all Kind 1 notes that Mention the pubkey within a time period. This is very good for quick use.
What wasn't clear to me initially (until Ocknamo helped me out) is that advanced use cases are also possible.
Each node also has an advanced mode. For example, the "Read" Node can have "Strategy" set to "RawFilter(advanced)". Now the node will accept json (anything you like that complies with NIP-01). You can use this to query Notes (Kind 1) as above, and also Profiles (Kind 0), Follow Lists (Kind 3), Reactions (Kind 7), Zaps (Kind 9734/9735), and anything else you can think of.
Creating and adding workflows
With n8n and Nostrobots installed, you can now create or add any kind of Nostr Workflow Automation.
- Click "Add workflow" to go to the workflow builder screen,
- If you would like to build your own workflow, you can start with adding any node. Click "+" and see what is available. Type "Nostr" to explore the Nostrobots nodes you have added,
- If you would like to add workflows that someone else has built, click "..." in the top right. Then click "import from URL" and paste in the URL of any workflow you would like to use (including the ones I share later in this article).
Nostr Workflow Automations
It's time to build some things!
A simple form to post a note to Nostr
I started very simply. I needed to delegate the ability to post to Npubs that I own in order that a (future) team can test things for me. I don't want to worry about managing or training those people on how to use keys, and I want to revoke access easily.
I needed a basic form with credentials that posted a Note.
For this I can use a very simple workflow–
- A n8n Form node – Creates a form for users to enter the note they wish to post. Allows for the form to be protected by a username and password. This node is the workflow "trigger" so that the workflow runs each time the form is submitted.
- A Set node – Allows me to set some variables, in this case I set the relays that I intend to use. I typically add a Set node immediately following the trigger node, and put all the variables I need in this. It helps to make the workflows easier to update and maintain.
- A Nostr Write node (from Nostrobots) – Writes a Kind-1 note to the Nostr network. It accepts Nostr credentials, the output of the Form node, and the relays from the Set node, and posts the Note to those relays.
Once the workflow is built, you can test it with the testing form URL, and set it to "Active" to use the production form URL. That's it. You can now give posting access to anyone for any Npub. To revoke access, simply change the credentials or set to workflow to "Inactive".
It may also be the world's simplest Nostr client.
You can find the Nostr Form to Post a Note workflow here.
Push notifications on mentions and new notes
One of the things Nostr is not very good at is push notifications. Furthermore I have some unique itches to scratch. I want–
- To make sure I never miss a note addressed to any of my Npubs – For this I want a push notification any time any Nostr user mentions any of my Npubs,
- To make sure I always see all notes from key accounts – For this I need a push notification any time any of my Npubs post any Notes to the network,
- To get these notifications on all of my devices – Not just my phone where my Nostr regular client lives, but also on each of my laptops to suit wherever I am working that day.
I needed to build a Nostr push notifications solution.
To build this workflow I had to string a few ideas together–
- Triggering the node on a schedule – Nostrobots does not include a trigger node. As every workflow starts with a trigger we needed a different method. I elected to run the workflow on a schedule of every 10-minutes. Frequent enough to see Notes while they are hot, but infrequent enough to not burden public relays or get rate-limited,
- Storing a list of Npubs in a Nostr list – I needed a way to store the list of Npubs that trigger my notifications. I initially used an array defined in the workflow, this worked fine. Then I decided to try Nostr lists (NIP-51, kind 30000). By defining my list of Npubs as a list published to Nostr I can control my list from within a Nostr client (e.g. Listr.lol or Nostrudel.ninja). Not only does this "just work", but because it's based on Nostr lists automagically Amethyst client allows me to browse that list as a Feed, and everyone I add gets notified in their Mentions,
- Using specific relays – I needed to query the right relays, including my own HAVEN relay inbox for notes addressed to me, and wss://purplepag.es for Nostr profile metadata,
- Querying Nostr events (with Nostrobots) – I needed to make use of many different Nostr queries and use quite a wide range of what Nostrobots can do–
- I read the EventID of my Kind 30000 list, to return the desired pubkeys,
- For notifications on mentions, I read all Kind 1 notes that mention that pubkey,
- For notifications on new notes, I read all Kind 1 notes published by that pubkey,
- Where there are notes, I read the Kind 0 profile metadata event of that pubkey to get the displayName of the relevant Npub,
- I transform the EventID into a Nevent to help clients find it.
- Using the Nostr URI – As I did with my NFC card article, I created a link with the
nostr:
URI prefix so that my phone's native client opens the link by default, - Push notifications solution – I needed a push notifications solution. I found many with n8n integrations and chose to go with Pushover which supports all my devices, has a free trial, and is unfairly cheap with a $5-per-device perpetual license.
Once the workflow was built, lists published, and Pushover installed on my phone, I was fully set up with push notifications on Nostr. I have used these workflows for several weeks now and made various tweaks as I went. They are feeling robust and I'd welcome you to give them a go.
You can find the Nostr Push Notification If Mentioned here and If Posts a Note here.
In speaking with other Nostr users while I was building this, there are all kind of other needs for push notifications too – like on replies to a certain bookmarked note, or when a followed Npub starts streaming on zap.stream. These are all possible.
Use my workflows
I have open sourced all my workflows at my Github with MIT license and tried to write complete docs, so that you can import them into your n8n and configure them for your own use.
To import any of my workflows–
- Click on the workflow of your choice, e.g. "Nostr_Push_Notify_If_Mentioned.json",
- Click on the "raw" button to view the raw JSON, ex any Github page layout,
- Copy that URL,
- Enter that URL in the "import from URL" dialog mentioned above.
To configure them–
- Prerequisites, credentials, and variables are all stated,
- In general any variables required are entered into a Set Node that follows the trigger node,
- Pushover has some extra setup but is very straightforward and documented in the workflow.
What next?
Over my first four blogs I explored creating a good Nostr setup with Vanity Npub, Lightning Payments, Nostr Addresses at Your Domain, and Personal Nostr Relay.
Then in my latest two blogs I explored different types of interoperability with NFC cards and now n8n Workflow Automation.
Thinking ahead n8n can power any kind of interoperability between Nostr and any other legacy technology solution. On my mind as I write this:
- Further enhancements to posting and delegating solutions and forms (enhanced UI or different note kinds),
- Automated or scheduled posting (such as auto-liking everything Lyn Alden posts),
- Further enhancements to push notifications, on new and different types of events (such as notifying me when I get a new follower, on replies to certain posts, or when a user starts streaming),
- All kinds of bridges, such as bridging notes to and from Telegram, Slack, or Campfire. Or bridging RSS or other event feeds to Nostr,
- All kinds of other automation (such as BlackCoffee controlling a coffee machine),
- All kinds of AI Assistants and Agents,
In fact I have already released an open source workflow for an AI Assistant, and will share more about that in my next blog.
Please be sure to let me know if you think there's another Nostr topic you'd like to see me tackle.

2025-04-03 07:42:25Spanien bleibt einer der Vorreiter im europäischen Prozess der totalen Überwachung per Digitalisierung. Seit Mittwoch ist dort der digitale Personalausweis verfügbar. Dabei handelt es sich um eine Regierungs-App, die auf dem Smartphone installiert werden muss und in den Stores von Google und Apple zu finden ist. Per Dekret von Regierungschef Pedro Sánchez und Zustimmung des Ministerrats ist diese Maßnahme jetzt in Kraft getreten.
Mit den üblichen Argumenten der Vereinfachung, des Komforts, der Effizienz und der Sicherheit preist das Innenministerium die «Innovation» an. Auch die Beteuerung, dass die digitale Variante parallel zum physischen Ausweis existieren wird und diesen nicht ersetzen soll, fehlt nicht. Während der ersten zwölf Monate wird «der Neue» noch nicht für alle Anwendungsfälle gültig sein, ab 2026 aber schon.
Dass die ganze Sache auch «Risiken und Nebenwirkungen» haben könnte, wird in den Mainstream-Medien eher selten thematisiert. Bestenfalls wird der Aspekt der Datensicherheit angesprochen, allerdings in der Regel direkt mit dem Regierungsvokabular von den «maximalen Sicherheitsgarantien» abgehandelt. Dennoch gibt es einige weitere Aspekte, die Bürger mit etwas Sinn für Privatsphäre bedenken sollten.
Um sich die digitale Version des nationalen Ausweises besorgen zu können (eine App mit dem Namen MiDNI), muss man sich vorab online registrieren. Dabei wird die Identität des Bürgers mit seiner mobilen Telefonnummer verknüpft. Diese obligatorische fixe Verdrahtung kennen wir von diversen anderen Apps und Diensten. Gleichzeitig ist das die Basis für eine perfekte Lokalisierbarkeit der Person.
Für jeden Vorgang der Identifikation in der Praxis wird später «eine Verbindung zu den Servern der Bundespolizei aufgebaut». Die Daten des Individuums werden «in Echtzeit» verifiziert und im Erfolgsfall von der Polizei signiert zurückgegeben. Das Ergebnis ist ein QR-Code mit zeitlich begrenzter Gültigkeit, der an Dritte weitergegeben werden kann.
Bei derartigen Szenarien sträuben sich einem halbwegs kritischen Staatsbürger die Nackenhaare. Allein diese minimale Funktionsbeschreibung lässt die totale Überwachung erkennen, die damit ermöglicht wird. Jede Benutzung des Ausweises wird künftig registriert, hinterlässt also Spuren. Und was ist, wenn die Server der Polizei einmal kein grünes Licht geben? Das wäre spätestens dann ein Problem, wenn der digitale doch irgendwann der einzig gültige Ausweis ist: Dann haben wir den abschaltbaren Bürger.
Dieser neue Vorstoß der Regierung von Pedro Sánchez ist ein weiterer Schritt in Richtung der «totalen Digitalisierung» des Landes, wie diese Politik in manchen Medien – nicht einmal kritisch, sondern sehr naiv – genannt wird. Ebenso verharmlosend wird auch erwähnt, dass sich das spanische Projekt des digitalen Ausweises nahtlos in die Initiativen der EU zu einer digitalen Identität für alle Bürger sowie des digitalen Euro einreiht.
In Zukunft könnte der neue Ausweis «auch in andere staatliche und private digitale Plattformen integriert werden», wie das Medienportal Cope ganz richtig bemerkt. Das ist die Perspektive.

2025-05-11 19:29:26"Misterija Satoši - Poreklo bitkoina" je francuski dokumentarno-animirani serijal koji dešifruje unutrašnje funkcionisanje bitkoin revolucije, dok istražuje identitet njenog tvorca.
Prvu decentralizovanu i pouzdanu kriptovalutu – bitkoin, osnovao je Satoši Nakamoto 3. januara 2009. godine. On je nestao 2011. i od tada ostaje anoniman, a njegov identitet je predmet svakakvih spekulacija. Tokom poslednjih 12 godina, vrednost bitkoina je porasla sa 0,001 na 69.000 dolara. Svi, od vlada do velikih korporacija, zainteresovali su se za Satošijev izum. Ko je Satoši Nakamoto? Kako je njegov izum postao toliko popularan? Šta nam bitkoin govori o svetu u kome živimo?
Ovaj serijal se prikazivao na Radio-televiziji Srbije (RTS 3) u sklopu novogodišnjeg muzičkog i filmskog programa 2022/2023. godine.

2025-05-11 18:57:51Originalni tekst na vice.com.
Davno pre nego što je postala šef najdesnije italijanske vlade od Drugog svetskog rata, Đorđa Meloni je kritikovala ono što je nazvala francuskom „kolonijalnom valutom“.
U snimku italijanske televizije iz 2019. koji je prošlog meseca postao megaviralan, Meloni je optužila Francusku da koristi CFA franak za eksploataciju resursa 14 afričkih zemalja i vrši finansijsku dominaciju nad njima. Određene stvari koje je tvrdila u videu nisu baš tačne, ali CFA franak jeste kontroverzan.
CFA franak je stvoren 1945. da bude valuta „francuskih kolonija u Africi“, a pošto Francuska kontroliše njegovo štampanje i promet, francuska vlada i dalje ima finansijsku kontrolu nad dobrim delom zapadnoafričke zemlje i više od 180 miliona ljudi. Dok su francuski zvaničnici ranije nazivali ovu valutu „činom velikodušnosti prema kolonijama“, o njenoj upotrebi se sada žestoko raspravlja.
Neke od afričkih nacija borile su se protiv valute, uključujući građane koji su razbijali prodavnice povezane sa Francuskom i osuđivali francuski jezik koji se uči u školama.
Jedna od onih 14 afričkih zemalja koja još uvek koristi CFA franak je Centralnoafrička Republika, država bez izlaza na more u kojoj živi oko 5 miliona ljudi i jedna od najsiromašnijih zemalja na svetu.

Ali dok druge afričke nacije razmatraju odbacivanje CFA franka, CAR je jedna od prvih koja je zaista uradila nešto po tom pitanju, a ranije ove godine postala je prva zemlja u Africi i tek druga u svetu koja je usvojila Bitcoin kao legalnu valutu.
„Alternativa gotovini je kriptovaluta“, rekao je predsednik Faustin-Aršanž Touadera. „Za nas formalna ekonomija više nije opcija”.
Dok su prve najave o bitkoinu izazvale konfuziju, međunarodne nesuglasice i reakcije, vlada CAR-a je nastavila sa uvođenjem. Osam meseci kasnije, mnogi ljudi širom sveta, pa čak i građani CAR-a, možda nisu ni svesni da se promena dogodila.
U CAR samo 14 odsto stanovništva ima pristup električnoj energiji, a još manje – oko 10 odsto – može da koristi internet. A konflikt i dalje tinja i negativno utiče na zemlju i njenu ekonomiju već deceniju.
Na predstavljanju bitkoina, vlada CAR-a je rekla da će usvajanje valute promeniti bogatstvo zemlje i staviti CAR „na mapu najhrabrijih i najvizionarskijih zemalja sveta“.
Bitkoin ne kontroliše nikakva moć, tehnički je univerzalno dostupan i ne može se cenzurisati – što je velika promena u odnosu na drugu valutu nacije, ali prosečnom građaninu CAR bi bilo potrebno 60 godina da kupi jedan novčić.

U Bangiju – glavnom gradu CAR – studenti Univerziteta rekli su za VICE da se „ništa nije promenilo“ od velike najave vlade.
Studenti su želeli da ostanu anonimni jer su se plašili da negativno govore o ambicijama vlade. Pravo na slobodu izražavanja ne postoji u CAR, a građani često doživljavaju zastrašivanje i nasilje od strane provladinih milicija, oružanih grupa i snaga nacionalne bezbednosti.
„Bilo je ogromno slavlje kada je objavljen Bitcoin plan i svi smo bili ponosni na našu zemlju“, rekao je jedan 20-godišnjak, „ali ne mislim da se život ovde uopšte poboljšao od tada”.
Drugi student je dodao: „Nigde nema cena u radnjama izraženih u bitkoioni, niti iko traži od ljudi da plaćaju koristeći novu valutu. Većina trgovaca i kupaca na tržištu nemaju telefon ili internet. Posebno ljudi izvan Bangija, nemaju ništa““.
Aleks Lilaher, osnivač i izvršni direktor Rise Up Media – marketinške agencije koja radi sa bitkoin startapima – je saglasan sa studentima, rekavši za VICE koliko je „iznenađen” što je ta zemlja uopšte napravila takavpotez.
„Centralnoafrička Republika nije baš lider u tehnologiji na kontinentu, i činilo se da tamo nikada nije bilo mnogo bitkoin korisnika koji bi mogla da lobiraju za takav potez“, rekao je on.

Upitan da li građani CAR-a treba da vide usvajanje bitkoina kao pozitivnu ili negativnu stvar, Lilaher je odgovorio „ni jedno ni drugo, jer jednostavno ne mogu da vidim da će usvajanje uskoro krenuti. Ali imati alternativu i poslati signal Francuskoj da CAR želi da ima više nezavisnosti od valute je pozitivno u mojim očima”.
Dodaje: „Međutim, to takođe može imati posledice jer postoje moćne institucije poput Međunarodnog monetarnog fonda, na primer, sa kojima CAR mora da se bavi, koje nisu srećne što zemlje usvajaju bitkoin. Dakle, moglo bi doći do izazova sa kojima će vlada morati da se nosi“.
Centralnoafrička Republika je druga zemlja u svetu koja je usvojila bitkoin, a prva je El Salvador u septembru 2021. Lansiranje valute je tamo imalo različite rezultate, a nedavno je opisano kao „antiklimaktično“ i samo ga turisti zaista koriste.
Iako su ljudi možda očekivali da će druge nacije pratiti El Salvador, sigurno ne bi pomislili da će CAR odgovarati računu.
Glavna opoziciona stranka CAR-a bila je protiv tog predloga od samog početka. Banka centralnoafričkih država je takođe nazvala ovaj potez „problematičnim“ i navela da bi usvajanje valute uz CFA moglo ugroziti odnos nacije sa drugim afričkim zemljama.
Čak i kada većina ljudi u CAR-u nije mogla da investira u Bitcoin, i sve poruke upozorenja, u julu je vlada CAR-a lansirala sopstvenu kriptovalutu – „Sangocoin“. Sango je lokalni jezik koji se govori širom zemlje.

Sangocoin neki vide kao budućnost CAR-a, a zahtevao je minimalnu investiciju od 500 dolara. Zauzvrat, investitori su mogli da kupe zemljište u zemlji bogatoj dijamantima za 10.000 dolara, pa čak i da kupe državljanstvo CAR-a za oko 60.000 dolara – iako je ove ponude kasnije blokirao najviši sud zemlje. Sangocoin investitori su takođe trenutno „zaključani“ za kupovinu, bez načina da kriptovalutu prodaju ili razmene.
Bio je to hrabar potez vlade, ali izgleda da se još uvek nije isplatio.
Ovog meseca, Centralnoafrička Republika je saopštila da odlaže puštanje nacionalne kriptovalute na kripto berze – što bi olakšalo međunarodnu trgovinu. Rojters kaže da je vlada okrivila „trenutne tržišne uslove” i „tržišne razloge”, ali je novinska agencija izračunala da je Sangocoin dostigao samo „0,01%” od najnovijeg vladinog cilja prodaje.
Još jedan skeptik je Aleks Gladštajn, glavni strateški službenik Fondacije za ljudska prava. On je dugogodišnji zagovornik usvajanja bitkoina u svetu u razvoju, kao i kritičar CFA franka – ali čak i on oseća da je CAR-ova šema bila „izuzetno neosmišljena“.
„Iako imam mnogo simpatije prema ranjivoj i siromašnoj naciji koja usvaja bitkoin kao drugu valutu – posebno naciji koja je decenijama i decenijama finansijski kontrolisana od strane svoje bivše kolonijalne sile, nisam baš optimističan u pogledu toga kako je to izvedeno“, rekao je za VICE.

Dodao je: „Zaista se čini da je cela ova stvar bila kao prevara da se Sangocoin promoviše. Ne mislim da je cilj bio da se bitkoin integriše na smislen način u ekonomiju zemlje. Čini se da je predsednik zainteresovan za bitkoin i da postoji mala grupa ljudi oko njega koja je iskoristila taj interes da bi mogla da donese ove zakone kako bi pokušala da pokrene Sangocoin, od kojeg su imali viziju da zarade gomilu novca. Ali izgleda da je na kraju uspela da prikupi samo malo novca.”
Gladstein kaže da bi Bitcoin mogao biti „veoma važna finansijska tehnologija za ljude Centralnoafričke Republike tokom vremena, i pametno je da vlada istraži kako to može pomoći ljudima“, ali je potrebno mnogo posla da se to postigne.
Vlada Centralnoafričke Republike i opoziciona vlada nisu odgovorile na nekoliko zahteva za intervju.

2025-03-31 21:48:50In seinem Beitrag vom 30. März 2025 fragt Henning Rosenbusch auf Telegram angesichts zunehmender digitaler Kontrolle und staatlicher Allmacht:
„Wie soll sich gegen eine solche Tyrannei noch ein Widerstand formieren können, selbst im Untergrund? Sehe ich nicht.“\ (Quelle: t.me/rosenbusch/25228)
Er beschreibt damit ein Gefühl der Ohnmacht, das viele teilen: Eine Welt, in der Totalitarismus nicht mehr mit Panzern, sondern mit Algorithmen kommt. Wo Zugriff auf Geld, Meinungsfreiheit und Teilhabe vom Wohlverhalten abhängt. Der Bürger als kontrollierbare Variable im Code des Staates.\ Die Frage ist berechtigt. Doch die Antwort darauf liegt nicht in alten Widerstandsbildern – sondern in einer neuen Realität.
-- Denn es braucht keinen Untergrund mehr. --
Der Widerstand der Zukunft trägt keinen Tarnanzug. Er ist nicht konspirativ, sondern transparent. Nicht bewaffnet, sondern mathematisch beweisbar. Bitcoin steht nicht am Rand dieser Entwicklung – es ist ihr Fundament. Eine Bastion aus physikalischer Realität, spieltheoretischem Schutz und ökonomischer Wahrheit. Es ist nicht unfehlbar, aber unbestechlich. Nicht perfekt, aber immun gegen zentrale Willkür.
Hier entsteht kein „digitales Gegenreich“, sondern eine dezentrale Renaissance. Keine Revolte aus Wut, sondern eine stille Abkehr: von Zwang zu Freiwilligkeit, von Abhängigkeit zu Selbstverantwortung. Diese Revolution führt keine Kriege. Sie braucht keine Führer. Sie ist ein Netzwerk. Jeder Knoten ein Individuum. Jede Entscheidung ein Akt der Selbstermächtigung.
Weltweit wachsen Freiheits-Zitadellen aus dieser Idee: wirtschaftlich autark, digital souverän, lokal verankert und global vernetzt. Sie sind keine Utopien im luftleeren Raum, sondern konkrete Realitäten – angetrieben von Energie, Code und dem menschlichen Wunsch nach Würde.
Der Globalismus alter Prägung – zentralistisch, monopolistisch, bevormundend – wird an seiner eigenen Hybris zerbrechen. Seine Werkzeuge der Kontrolle werden ihn nicht retten. Im Gegenteil: Seine Geister werden ihn verfolgen und erlegen.
Und während die alten Mächte um Erhalt kämpfen, wächst eine neue Welt – nicht im Schatten, sondern im Offenen. Nicht auf Gewalt gebaut, sondern auf Mathematik, Physik und Freiheit.
Die Tyrannei sieht keinen Widerstand.\ Weil sie nicht erkennt, dass er längst begonnen hat.\ Unwiderruflich. Leise. Überall.

2024-12-08 09:05:13Yalnızca güçlü olanların hakkıdır yaşamak.
Güçlü olan ileri gider ve saflar seyrekleşir. Ama üç beş büyük, güçlü ve tanrısal kişi güneşli ve aydınlık gözleriyle o yeni, o vaat edilmiş ülkeye ulaşacaktır. Belki binlerce yıl sonra ancak. Ve güçlü, adaleli, hükmetmek için yaratılmış elleriyle hastaların, zayıfların ve sakatların ölüleri üzerinde bir krallık kuracaklardır. Bir krallık!
Benim aradığım insanların kendileri değil, sesleridir.
Duyguları körelmiş, çeşitli düşüncelere saplanmış kalabalık hiçbir zaman ilerlemenin taşıyıcısı olamaz, kendi küçüklüğünün o küflü içgüdüsüyle kalabalığın kin ve nefretle baktığı bir kişi, bir büyük kişi, iradesinin gösterdiği yolda kimsenin gözünün yaşına bakmaksızın ilahi bir güç ve bir zafer gülümsemesiyle yürüyebilir ancak.
Bizim soyumuz da sonsuz oluşum piramidinin doruk noktasını oluşturmaktan uzaktır. Bizler de mükemmelliğe ulaşmış değiliz. Bizler de henüz olgunlaşmadık.
Şairler sevgiye övgüler döşenir; doğrusu sevginin güçlü bir şey olduğu kesin. Hüneşin bir ışınıdır sevgi, aydınlatıp nurlandırır insanı der bazıları; bazıları da insanı esrikliğe sürükleyen bir zehri kendisinde barındırdığını söyler. Gerçekten de yol açtığı sonuçlar, bir hekimin ağır bir ameliyattan önce korkudan titreyen hastaya teneffüs ettirdiği güldürücü gazınkine benzer, içinde tepinip duran acıyı unutturur hastaya.
Önemli olan, hayatta hiç değilse bir kez kutsal bir ilkbaharın yaşanmasıdır; öyle bir bahar ki, insanın gönlünü ilerideki bütün günleri altın yaldızla kaplamaya yetecek kadar ışık ve parıltıyla doldursun.
Şu hayat denen şey kötü bir işçiliğin ürünü, acemilere göre bir şey. Bu kepaze yaşam uğruna insan nelere katlanmıyor ki!
Kendisine sadakatten ayrılmadığı, yalnızca kendisinin olan bir tek bu var: Yalnızlığı.
Sahildeki üstü tenteli hasır koltuklar arkasındaki yüksek, sessiz kum tepeleri içinde yürürsen, tenteler altındaki insanları göremezsin; ama birinin bir diğerine seslendiğini, bir başkasının gevezelik ettiğini, bir ötekinin güldüğünü işitir ve anlarsın hemen: bu insan şöyle şöyle biridir diyebilirsin. Onun hayatı sevdiğini, bağrında büyük bir özlem ya da acı barındırdığını, bu acının da sesini ağlamaklı kıldığını her gülüşünde hissedersin.

2025-03-31 07:23:05Der Irrsinn ist bei Einzelnen etwas Seltenes – \ aber bei Gruppen, Parteien, Völkern, Zeiten die Regel. \ Friedrich Nietzsche
Erinnern Sie sich an die Horrorkomödie «Scary Movie»? Nicht, dass ich diese Art Filme besonders erinnerungswürdig fände, aber einige Szenen daraus sind doch gewissermaßen Klassiker. Dazu zählt eine, die das Verhalten vieler Protagonisten in Horrorfilmen parodiert, wenn sie in Panik flüchten. Welchen Weg nimmt wohl die Frau in der Situation auf diesem Bild?
Diese Szene kommt mir automatisch in den Sinn, wenn ich aktuelle Entwicklungen in Europa betrachte. Weitreichende Entscheidungen gehen wider jede Logik in die völlig falsche Richtung. Nur ist das hier alles andere als eine Komödie, sondern bitterernst. Dieser Horror ist leider sehr real.
Die Europäische Union hat sich selbst über Jahre konsequent in eine Sackgasse manövriert. Sie hat es versäumt, sich und ihre Politik selbstbewusst und im Einklang mit ihren Wurzeln auf dem eigenen Kontinent zu positionieren. Stattdessen ist sie in blinder Treue den vermeintlichen «transatlantischen Freunden» auf ihrem Konfrontationskurs gen Osten gefolgt.
In den USA haben sich die Vorzeichen allerdings mittlerweile geändert, und die einst hoch gelobten «Freunde und Partner» erscheinen den europäischen «Führern» nicht mehr vertrauenswürdig. Das ist spätestens seit der Münchner Sicherheitskonferenz, der Rede von Vizepräsident J. D. Vance und den empörten Reaktionen offensichtlich. Große Teile Europas wirken seitdem wie ein aufgescheuchter Haufen kopfloser Hühner. Orientierung und Kontrolle sind völlig abhanden gekommen.
Statt jedoch umzukehren oder wenigstens zu bremsen und vielleicht einen Abzweig zu suchen, geben die Crash-Piloten jetzt auf dem Weg durch die Sackgasse erst richtig Gas. Ja sie lösen sogar noch die Sicherheitsgurte und deaktivieren die Airbags. Den vor Angst dauergelähmten Passagieren fällt auch nichts Besseres ein und so schließen sie einfach die Augen. Derweil übertrumpfen sich die Kommentatoren des Events gegenseitig in sensationslüsterner «Berichterstattung».
Wie schon die deutsche Außenministerin mit höchsten UN-Ambitionen, Annalena Baerbock, proklamiert auch die Europäische Kommission einen «Frieden durch Stärke». Zu dem jetzt vorgelegten, selbstzerstörerischen Fahrplan zur Ankurbelung der Rüstungsindustrie, genannt «Weißbuch zur europäischen Verteidigung – Bereitschaft 2030», erklärte die Kommissionspräsidentin, die «Ära der Friedensdividende» sei längst vorbei. Soll das heißen, Frieden bringt nichts ein? Eine umfassende Zusammenarbeit an dauerhaften europäischen Friedenslösungen steht demnach jedenfalls nicht zur Debatte.
Zusätzlich brisant ist, dass aktuell «die ganze EU von Deutschen regiert wird», wie der EU-Parlamentarier und ehemalige UN-Diplomat Michael von der Schulenburg beobachtet hat. Tatsächlich sitzen neben von der Leyen und Strack-Zimmermann noch einige weitere Deutsche in – vor allem auch in Krisenzeiten – wichtigen Spitzenposten der Union. Vor dem Hintergrund der Kriegstreiberei in Deutschland muss eine solche Dominanz mindestens nachdenklich stimmen.
Ihre ursprünglichen Grundwerte wie Demokratie, Freiheit, Frieden und Völkerverständigung hat die EU kontinuierlich in leere Worthülsen verwandelt. Diese werden dafür immer lächerlicher hochgehalten und beschworen.
Es wird dringend Zeit, dass wir, der Souverän, diesem erbärmlichen und gefährlichen Trauerspiel ein Ende setzen und die Fäden selbst in die Hand nehmen. In diesem Sinne fordert uns auch das «European Peace Project» auf, am 9. Mai im Rahmen eines Kunstprojekts den Frieden auszurufen. Seien wir dabei!

2025-03-23 11:39:41I don't believe in "vibe coding" – it's just the newest Silicon Valley fad trying to give meaning to their latest favorite technology, LLMs. We've seen this pattern before with blockchain, when suddenly Non Fungible Tokens appeared, followed by Web3 startups promising to revolutionize everything from social media to supply chains. VCs couldn't throw money fast enough at anything with "decentralized" (in name only) in the pitch deck. Andreessen Horowitz launched billion-dollar crypto funds, while Y Combinator batches filled with blockchain startups promising to be "Uber for X, but on the blockchain."
The metaverse mania followed, with Meta betting its future on digital worlds where we'd supposedly hang out as legless avatars. Decentralized (in name only) autonomous organizations emerged as the next big thing – supposedly democratic internet communities that ended up being the next scam for quick money.
Then came the inevitable collapse. The FTX implosion in late 2022 revealed fraud, Luna/Terra's death spiral wiped out billions (including my ten thousand dollars), while Celsius and BlockFi froze customer assets before bankruptcy.
By 2023, crypto winter had fully set in. The SEC started aggressive enforcement actions, while users realized that blockchain technology had delivered almost no practical value despite a decade of promises.
Blockchain's promises tapped into fundamental human desires – decentralization resonated with a generation disillusioned by traditional institutions. Evangelists presented a utopian vision of freedom from centralized control. Perhaps most significantly, crypto offered a sense of meaning in an increasingly abstract world, making the clear signs of scams harder to notice.
The technology itself had failed to solve any real-world problems at scale. By 2024, the once-mighty crypto ecosystem had become a cautionary tale. Venture firms quietly scrubbed blockchain references from their websites while founders pivoted to AI and large language models.
Most reading this are likely fellow bitcoiners and nostr users who understand that Bitcoin is blockchain's only valid use case. But I shared that painful history because I believe the AI-hype cycle will follow the same trajectory.
Just like with blockchain, we're now seeing VCs who once couldn't stop talking about "Web3" falling over themselves to fund anything with "AI" in the pitch deck. The buzzwords have simply changed from "decentralized" to "intelligent."
"Vibe coding" is the perfect example – a trendy name for what is essentially just fuzzy instructions to LLMs. Developers who've spent years honing programming skills are now supposed to believe that "vibing" with an AI is somehow a legitimate methodology.
This might be controversial to some, but obvious to others:
Formal, context-free grammar will always remain essential for building precise systems, regardless of how advanced natural language technology becomes
The mathematical precision of programming languages provides a foundation that human language's ambiguity can never replace. Programming requires precision – languages, compilers, and processors operate on explicit instructions, not vibes. What "vibe coding" advocates miss is that beneath every AI-generated snippet lies the same deterministic rules that have always governed computation.
LLMs don't understand code in any meaningful sense—they've just ingested enormous datasets of human-written code and can predict patterns. When they "work," it's because they've seen similar patterns before, not because they comprehend the underlying logic.
This creates a dangerous dependency. Junior developers "vibing" with LLMs might get working code without understanding the fundamental principles. When something breaks in production, they'll lack the knowledge to fix it.
Even experienced developers can find themselves in treacherous territory when relying too heavily on LLM-generated code. What starts as a productivity boost can transform into a dependency crutch.
The real danger isn't just technical limitations, but the false confidence it instills. Developers begin to believe they understand systems they've merely instructed an AI to generate – fundamentally different from understanding code you've written yourself.
We're already seeing the warning signs: projects cobbled together with LLM-generated code that work initially but become maintenance nightmares when requirements change or edge cases emerge.
The venture capital money is flowing exactly as it did with blockchain. Anthropic raised billions, OpenAI is valued astronomically despite minimal revenue, and countless others are competing to build ever-larger models with vague promises. Every startup now claims to be "AI-powered" regardless of whether it makes sense.
Don't get me wrong—there's genuine innovation happening in AI research. But "vibe coding" isn't it. It's a marketing term designed to make fuzzy prompting sound revolutionary.
Cursor perfectly embodies this AI hype cycle. It's an AI-enhanced code editor built on VS Code that promises to revolutionize programming by letting you "chat with your codebase." Just like blockchain startups promised to "revolutionize" industries, Cursor promises to transform development by adding LLM capabilities.
Yes, Cursor can be genuinely helpful. It can explain unfamiliar code, suggest completions, and help debug simple issues. After trying it for just an hour, I found the autocomplete to be MAGICAL for simple refactoring and basic functionality.
But the marketing goes far beyond reality. The suggestion that you can simply describe what you want and get production-ready code is dangerously misleading. What you get are approximations with:
- Security vulnerabilities the model doesn't understand
- Edge cases it hasn't considered
- Performance implications it can't reason about
- Dependency conflicts it has no way to foresee
The most concerning aspect is how such tools are marketed to beginners as shortcuts around learning fundamentals. "Why spend years learning to code when you can just tell AI what you want?" This is reminiscent of how crypto was sold as a get-rich-quick scheme requiring no actual understanding.
When you "vibe code" with an AI, you're not eliminating complexity—you're outsourcing understanding to a black box. This creates developers who can prompt but not program, who can generate but not comprehend.
The real utility of LLMs in development is in augmenting existing workflows:
- Explaining unfamiliar codebases
- Generating boilerplate for well-understood patterns
- Suggesting implementations that a developer evaluates critically
- Assisting with documentation and testing
These uses involve the model as a subordinate assistant to a knowledgeable developer, not as a replacement for expertise. This is where the technology adds value—as a sophisticated tool in skilled hands.
Cursor is just a better hammer, not a replacement for understanding what you're building. The actual value emerges when used by developers who understand what happens beneath the abstractions. They can recognize when AI suggestions make sense and when they don't because they have the fundamental knowledge to evaluate output critically.
This is precisely where the "vibe coding" narrative falls apart.

2025-05-11 18:40:50Wir sprechen kein Wort mehr miteinander, weil es weh tut
Viele Menschen haben in den letzten Jahren den Kontakt zu wichtigen Bezugspersonen verloren. Viele Menschen haben auch neue Leute auf der Straße oder durch Netzwerke kennen gelernt. Und manche Menschen hatten das Glück, schon vor der inszenierten Krise einen unterstützenden und stabilen Freundeskreis zu haben und haben diesen immer noch. Manchmal kommen alte Leute wieder zurück ins Leben, weil sie merken, dass man es gut mit ihnen meinte, als man vor den unglaublichen Lügen der Amtsträger warnte. Manchmal kommen alte Leute auch nicht mehr zurück, weil die Scham, auf falsche Versprechen herein gefallen zu sein, zu groß ist. Man gibt sich dann nach außen unverändert souverän und zieht es vor, still und heimlich zu leiden. Die neuen Kontakte bestehen manchmal leider auch nur temporär, sind zweckgebunden. Kaum ist die gemeinsame Aufgabe vollbracht, trennen sich die Wege wieder.
All das muss man in diesen Tagen gehäuft aushalten. Alles verändert sich in stärkerem Maße als sonst. Viele dieser Veränderungen tun weh. Man kann sich auf Trauma nicht vorbereiten. Nie.
Ich möchte jetzt keine schlichten Alltagsbeobachtungen darüber widergeben, wie ich selbst oder Menschen in meinem Umfeld in den letzten Jahren ihre Beziehungen erlebt haben. Vielmehr geht es mir auch in diesem Artikel wieder um das Thema Trauma und um die Folgen, die jedes einzelne Trauma auch gesamtgesellschaftlich betrachtet hat. Was passiert, wenn man eine bereits durch Kriege traumatisierte Gesellschaft noch zusätzlich jahrelang unter Druck setzt, so wie dies in den letzten fünf Jahren geschehen ist? Wieviel Trauma verträgt eine Gesellschaft? Wie verändern sich Beziehungen in einer Gesellschaft, die immer wieder erneut traumatisiert wird? Ist irgendwann das Maß des Erträglichen voll? Und wenn ja, wie äußert sich solch eine Kumulation von Traumafolgen?
Meines Erachtens sehen wir gerade genau die Ergebnisse solch einer Kumulation von Traumafolgen in unserer deutschen Gesellschaft, vielleicht sogar global: Menschen reden nicht mehr (vertieft) miteinander. Und dies ist nur eine von vielen Traumafolgen.
Ich freue mich über jeden Leser, der jetzt noch weiterliest.
Durch genügend Traumatisierung kann man Menschen offensichtlich zeitweise dazu bringen, dass sie nicht mehr (vertieft) miteinander reden, weil das Reden weh tut.
Traumatisierung ist daher eine effektive Strategie der vermeintlich Herrschenden, Menschen zu separieren.
Traumatisierung setzt tiefe Verletzungen und macht Menschen vorübergehend sprachlos. Es fehlen einem die Worte. Man möchte dann nicht reden. Aber man verschließt sich auch vor den Worten anderer, weil man keine weitere Verletzung mehr erträgt.
Menschen im Alltag erachten es vielleicht mittlerweile schon als normal, wenn Beziehungen nicht gut laufen, egal, um welche Art von Beziehung es sich handelt. Sobald Probleme auftauchen, wird erst kurz gestritten, dann geschwiegen und wenn man das Schweigen nicht mehr aushält, dann gibt es entweder noch einen Versuch oder man geht gleich auf Distanz und bricht den Kontakt ganz ab. Auch meine Zündschnur ist manchmal immer noch gefühlt zu kurz. Wenn man sich Distanz nicht erlauben kann, dann frisst man das Problem in sich hinein, spült es runter, kompensiert irgendwie, wartet darauf, dass sich von allein etwas ändert oder dass sich eine bessere Gelegenheit bietet, bei der man dann die Biege machen kann. Mehrere Eisen im Feuer zu haben, beruflich wie privat, gilt als clever. Probleme nicht anzusprechen, gilt als kompetent. Das Wort Teamfähigkeit ist im Berufsleben zu einem Kampfbegriff geworden. Wer im Arbeitskontext Probleme anspricht, ist offensichtlich nicht teamfähig. Die Frage „Sind Sie teamfähig?“, erzählt meines Erachtens mehr über den Chef als über den Mitarbeiter. Die passendere Frage wäre wohl „Können Sie sich wortlos an schlechte Zustände dauerhaft adaptieren?“ In privaten Beziehungen braucht man, wenn es nicht so gut läuft, einen stilvollen Urlaub oder eine neue Wohnzimmereinrichtung, um endlich mal wieder schöne Gefühle erleben zu können. Negative Gefühle sind scheinbar das Kind, das keiner haben wollte, weshalb es die schönsten Kleider bekommt. Auch ich kenne Ablenkung von negativen Gefühlen durch Konsum und Essen. Es lohnt sich, mal den Werbeslogans von Möbelhäusern, Ferienanbietern oder Lebensmittelhändlern bewusst zuzuhören. Die Werbung kennt unsere Sehnsüchte und damit auch unsere negativen Gefühle besser als wir selbst. Und für alle, die nicht konsumieren wollen, die nicht locker lassen und steif darauf beharren, dass es aber ein Problem in der Beziehung oder am Arbeitsplatz oder zumindest eine gewisse Unzufriedenheit gäbe, für diese Menschen gibt es garantiert ein passendes Coaching- oder Weiterbildungsprogramm mit Namen wie „In 12 Modulen zur Selbstentfaltung“, welches nur deshalb meist nicht funktioniert, weil man es angeblich nicht richtig durchgeführt hat oder vorab noch das Basismodul absolvieren muss. Bildung ist mittlerweile auch ein Markt, der Konsumgüter in Form von Coachings und Seminaren anbietet.
Auch ich bin übrigens lange zusammen gezuckt bei der Frage „Sind sie teamfähig?“ oder der Feststellung „Du bist das Problem, weil Du immer alles so genau nimmst, nicht die Fünf gerade sein lassen kannst.“ Am Ende ist man immer der Dumme, wenn man ein negatives Gefühl hat und darüber sprechen möchte. Trauma löst Scham UND Wut in einer Person aus. Scham zieht Abwertung an wie Licht die Motten anzieht. Und irgendwann platzt einem der Kragen. Man teilt selber aus. Und dann schämt man sich erneut, nicht nur für das früher oder später erlittene Trauma im Leben, sofern einem das bewusst ist, sondern auch für die unbeherrschte Reaktion, die man oft selbst nicht richtig versteht. Nicht bearbeitetes Trauma arbeitet unbewusst in uns.
Eine traumatisierte Gesellschaft wertet sich ständig gegenseitig ab und hält genau damit die Wunden offen.
Dann ist es vielleicht doch besser, das Problem in der Beziehung oder am Arbeitsplatz runter zu schlucken, auf Distanz zum anderen zu gehen, sich schon mal nach einer neuen Wohnzimmereinrichtung, einem neuen Partner oder einem neuen Job umzuschauen? Ich denke nicht, dass das eine Lösung ist.
Hinschauen und Gefühle bei sich und anderen zulassen, ist ein guter Anfang.
Wir gehen oft Beziehungen ein, gehen aber gleichzeitig einer echten tiefen und anhaltenden Verbindungen privat wie beruflich instinktiv aus dem Weg, weil echte tiefe Gespräche, zu denen es in solchen Verbindungen kommen kann, weh tun können, insbesondere wenn man noch unverarbeitetes Trauma mit sich herum schleppt. Und in einer traumatisierten Gesellschaft, tragen halt viele Menschen solche traumatisierten und nicht bearbeiteten Anteile mit sich herum.
Wir sind die Kinder und Kindeskinder der Menschen, die den zweiten Weltkrieg hautnah miterlebt haben. Alles, was die Eltern und Großeltern nicht besprochen, nicht verarbeitet haben, tragen wir weiter mit uns herum. Das ist den meisten Menschen, meines Erachtens, nicht bewusst. Mag sein, dass an dieser Stelle der eine oder andere widerspricht. Widersprechen Sie mir gerne. Meine Alltagserfahrung ist eine andere. Die Art, wie wir Beziehungen gestalten, spricht Bände. Aber, wenn man es nicht anders kennt und keine Kontrollgruppe hat, sagt man sich halt: „So isses. Und so isses normal. Ich kenne es nicht anders. Das machen doch alle so.“
Es ist so normal, in unserer Gesellschaft, nicht vertieft über negative (und auch positive) Gefühle zu reden. Alleine die Bezeichnung „negative Gefühle“ klingt schon wenig einladend. Und es ist auch so normal, Menschen in dem Moment, wo sie gegen jede Empfehlung nicht nur über negative Gefühle reden wollen, sondern diese sogar live und in Farbe zeigen, abzuwerten, oder noch schlimmer, zu ignorieren, weil man sich verunsichert fühlt, nicht weiß, wie man damit umgehen soll. Gefühle scheinen ansteckend zu sein. Da ist Vorsicht geboten. Ich persönlich kann mich an viele solcher Momente erinnern, wo Menschen nicht gern hören wollten, wovor ich Angst hatte, was und wer mich verletzt und wütend gemacht hatte, beruflich wie privat. Mit geäußerter Angst und Trauer macht man(n) sich ganz schnell lächerlich. Mit Wut hingegen wird ein Mann von anderen als stark bis beängstigend wahrgenommen. Ein Mann, der wütend agiert, wird eher als kraftvoll und temperamentvoll eingeschätzt. Eine Frau wird mit Wut dann akzeptiert, wenn sie bereits in einer (männlichen) Führungsrolle ist. „Sie“ muss schließlich ihren „Mann“ stehen. Hat sie keine Führungsrolle, wird sie abgewertet oder befördert. Dem wütenden Mann wird eher unterstellt, er habe schließlich einen wichtigen Auftrag zu erfüllen. Der Frau wird eher ein Mangel unterstellt, den ich hier nicht näher bezeichnen möchte. Darin spiegeln sich sehr starre Rollenvorstellungen von Mann und Frau in unserer Gesellschaft wider. Ängstliche Frauen, die bei einer Autopanne bezaubernd aussehen, erfüllen ein bestimmtes Klischee. Impulsive Männer mit Holzfällerhemd erfüllen zumindest auf einer Baustelle ein anderes Klischee. Menschen mit ausgeprägten negativen Gefühlen werden unter bestimmten Umständen glorifiziert. Der bezaubernd aussehenden Frau mit Autopanne wird schnell und gerne geholfen. Aber wenn die ängstliche Frau eine Vorgesetzte ist und der impulsive Mann mit Holzfällerhemd ein Kunde in einem Beratungsbüro ist, dann kann die Bewertung ganz anders ausfallen. Dann sind diese Gefühle vermeintlich fehlplatziert. Gefühle scheinen einen Platz zu haben. Die ängstliche Vorgesetzte hat eine Führungsschwäche und der impulsive Kunde im Beratungsbüro wird vom Sicherheitsdienst „entfernt“. Der Wunsch, über die gezeigten negativen Gefühle zu reden, wird einem mit Nachdruck verwehrt. Durch diesen vermeidenden Umgang mit negativen Gefühlen oder die Fehlinterpretation dieser Gefühle kommt es meines Erachtens oft zu bestimmten Rollenbesetzungen im Berufsleben. Eine positive Selektion von Mitarbeitern mit sehr rücksichtslosem oder überangepasstem Verhalten findet statt. In privaten Beziehungen werden negative Gefühle durch Ablenkung und Konsum vermieden. Es werden zu viele oder zu wenige Kontakte gepflegt. Beziehungen werden gar nicht mehr für die Ewigkeit antizipiert. Man hält sich alle Wege offen und lernt ständig neue Leute kennen. Oder man lebt Beziehung in sehr starren Strukturen, wo neue Informationen kaum Eingang finden, damit man sich nicht hinterfragen und mit anderen vergleichen muss. Lebensphasen mit dem weit geöffneten oder dem eher geschlossenen Muster wechseln sich auch manchmal ab. Individuelle Entwicklungen des einen oder anderen Musters in Lebensverläufen, zeichnen sich irgendwann als gesellschaftliche Strömung ab, wenn sie bei vielen Menschen gleichzeitig geschehen. Menschen wollen alles ausprobiert haben, bevor sie sich das Reihenhaus kaufen. Andere verkaufen ihr Reihenhaus nach der Scheidung, um im Wohnmobil durch die Welt zu tingeln. Man könnte denken, dass dies einfach individuelle Lebensverläufe sind, die sich zufällig so ergeben haben. Es gab Zeiten, wo Menschen zufällig viel Halt in starren Beziehungs- und Lebensstrukturen fanden. Gegenbewegungen brachen diese starren Strukturen nicht wirklich auf, weil sie Feuer mit Feuer bekämpften. Grundsätzlich gegen alles zu sein, was die Eltern vorgelebt haben, ist ja auch irgendwie rigide. Der Apfel fällt nicht zufällig neben den Stamm. Heute 80 Jahre nach Kriegsende können Menschen mit Begriffen wie Achtsamkeit und bewusster Kommunikation immer mehr anfangen, jedoch geht die weit verbreitete Bewusstheit und Selbstreflektiertheit oft zu Lasten einer wünschenswerten Verarbeitungstiefe. Zu oft werden wir gedacht, gefühlt und gelenkt. Um dies mit uns machen zu können, werden von vermeintlich Herrschenden wichtige Orientierungspunkte wie die eigene Geschichte, Kultur und Sprache falsch erzählt oder bis zur Unkenntlichkeit verändert. Und eigene Gefühle, die einem noch letzten Halt und Orientierung in diesem Dschungel bieten könnten, werden vom Kapitalismus ausdauernd gejagt wie ein seltenes Tier. Separierung und Orientierungslosigkeit ist gewollt.
Alles dreht sich um unsere tiefen Gefühle, insbesondere diese negativen Gefühle, die aus Trauma entstehen. Diese Gefühle wollen gesehen, gehört und bearbeitet werden. Sie machen zum Glück, solange es die Menschheit gibt, zuverlässig auf sich selbst aufmerksam. Sie sind in Wahrheit unsere Lebensversicherung. Die Zeit heilt gar nichts. Und hierfür braucht es wieder ein Bewusstsein, dass Gefühle wertvoll sind, auch solche, die aus Trauma entstehen. Ich persönlich habe dafür mehr als ein halbes Leben gebraucht, um dies zu verstehen. Als junge Frau habe ich nicht gewusst, dass viele meiner Gefühle, negativ wie positiv, Ausdruck meines Traumas waren. Heute weiß ich, dass ich mit dieser Einschätzung, die ich damals hatte, in „guter Gesellschaft“ war. Den meisten Menschen geht das so, bis sie irgendwann ihr eigenes Trauma erkennen.
Wir sind eine traumatisierte Gesellschaft, und die Arten und Ausprägungen von Trauma sind so vielfältig und den meisten Menschen unbekannt wie die Namen der Blumen auf einer Sommerwiese.
Wenn man diesen Satz wirken lässt, dann stellt sich doch die Frage:
Wie sieht denn ein gesunder Umgang mit negativen (und positiven) Gefühlen aus?
Reicht es aus, wenn man die Namen aller Wiesenblumen auswendig lernt, damit man jedes Trauma genau bestimmen kann? Oder geht es mehr um das Fühlen und weniger um das Wissen?
Den gesunden Umgang mit meinen Gefühlen habe ich nicht durch Theorie und Bücher erlernt, sondern durch den Alltag, durch die (emotionalen) Reaktionen meiner Mitmenschen und durch das bewusste Spüren und Zulassen meiner eigenen Gefühle. In Stufen lernte ich meine Gefühle immer besser kennen und mit ihnen umzugehen. Je besser ich sie kannte, umso lieber waren sie mir. Und ich lerne sie immer noch weiter und besser kennen. Das ist ein Prozess.
Traumabearbeitung ist anfangs ein anstrengender Prozess. Man sollte das langsam angehen. Aber diese Arbeit ist sehr lohnenswert, weil sie einem viele glückliche Momente, Kraft und Lebensfreude schenkt. Reden wird dadurch leichter und bringt in allen Lebensbereichen Fortschritte. Manchmal tut Reden auch weh (siehe Titel), aber zeitgleich, und auch langfristig gesehen, wird das Leben schöner durch Traumabearbeitung. Es geht nicht um Schmerzvermeidung, sondern darum, mit dem Schmerz gut umgehen zu können. Denn dadurch wird er letztlich kleiner und verwandelt sich zur Wiesenblume. Es geht um Verwandlung durch Fühlen. Die Erfahrung, dass man Trauma bearbeiten kann, erzählt mir so viel über dieses Leben, wie stark es ist, wie sehr es uns liebt und welche Blüten daraus wachsen können. Viele schöne Dinge, die wir täglich sehen, sind aus bewältigtem Trauma oder dem Wunsch, Trauma zu bewältigen, entstanden.
Der Schmerz lehrt uns Demut vor dem Leben und kreiert nebenbei die schönsten Lieder und Kunstwerke. Trauer und Verlust betonen den Wert der Dinge. Ärger und Wut bringen uns in Wallungen und stellen die Energie bereit, die man manchmal braucht, um Berge zu versetzen. Ängste sind das Tor zum Glück. Schuld und Scham lehren uns Vergebung. Neid und Eifersucht lassen unseren Selbstwert wachsen, wenn wir uns ihnen stellen. Und Freude, Glück und Ekstase machen uns dankbar, großzügig und optimistisch.
Wenn wir diese Gefühle wieder zulassen, dann können wir gar nicht anders als reden. Wir reden dann wieder vertieft miteinander, weil es gut tut, weil es entlastet, weil es Nähe zu anderen vielleicht erstmalig aufbaut und dann zu einem dicken Band verstärkt bis ein großes stabiles Netz daraus entsteht, welches Menschen, die gerade Halt benötigen, diesen bieten kann.
Wir reden dann wieder miteinander, weil es gut tut.

Fiduciary duty is the obligation to act in the client’s best interests at all times, prioritizing their needs above the advisor’s own, ensuring honesty, transparency, and avoiding conflicts of interest in all recommendations and actions.
This is something all advisors in the BFAN take very seriously; after all, we are legally required to do so. For the average advisor this is a fairly easy box to check. All you essentially have to do is have someone take a 5-minute risk assessment, fill out an investment policy statement, and then throw them in the proverbial 60/40 portfolio. You have thousands of investment options to choose from and you can reasonably explain how your client is theoretically insulated from any move in the \~markets\~. From the traditional financial advisor perspective, you could justify nearly anything by putting a client into this type of portfolio. All your bases were pretty much covered from return profile, regulatory, compliance, investment options, etc. It was just too easy. It became the household standard and now a meme.
As almost every real bitcoiner knows, the 60/40 portfolio is moving into psyop territory, and many financial advisors get clowned on for defending this relic on bitcoin twitter. I’m going to specifically poke fun at the ‘40’ part of this portfolio.
The ‘40’ represents fixed income, defined as…
An investment type that provides regular, set interest payments, such as bonds or treasury securities, and returns the principal at maturity. It’s generally considered a lower-risk asset class, used to generate stable income and preserve capital.
Historically, this part of the portfolio was meant to weather the volatility in the equity markets and represent the “safe” investments. Typically, some sort of bond.
First and foremost, the fixed income section is most commonly constructed with U.S. Debt. There are a couple main reasons for this. Most financial professionals believe the same fairy tale that U.S. Debt is “risk free” (lol). U.S. debt is also one of the largest and most liquid assets in the market which comes with a lot of benefits.
There are many brilliant bitcoiners in finance and economics that have sounded the alarm on the U.S. debt ticking time bomb. I highly recommend readers explore the work of Greg Foss, Lawrence Lepard, Lyn Alden, and Saifedean Ammous. My very high-level recap of their analysis:
-
A bond is a contract in which Party A (the borrower) agrees to repay Party B (the lender) their principal plus interest over time.
-
The U.S. government issues bonds (Treasury securities) to finance its operations after tax revenues have been exhausted.
-
These are traditionally viewed as “risk-free” due to the government’s historical reliability in repaying its debts and the strength of the U.S. economy
-
U.S. bonds are seen as safe because the government has control over the dollar (world reserve asset) and, until recently (20 some odd years), enjoyed broad confidence that it would always honor its debts.
-
This perception has contributed to high global demand for U.S. debt but, that is quickly deteriorating.
-
The current debt situation raises concerns about sustainability.
-
The U.S. has substantial obligations, and without sufficient productivity growth, increasing debt may lead to a cycle where borrowing to cover interest leads to more debt.
-
This could result in more reliance on money creation (printing), which can drive inflation and further debt burdens.
In the words of Lyn Alden “Nothing stops this train”
Those obligations are what makes up the 40% of most the fixed income in your portfolio. So essentially you are giving money to one of the worst capital allocators in the world (U.S. Gov’t) and getting paid back with printed money.
As someone who takes their fiduciary responsibility seriously and understands the debt situation we just reviewed, I think it’s borderline negligent to put someone into a classic 60% (equities) / 40% (fixed income) portfolio without serious scrutiny of the client’s financial situation and options available to them. I certainly have my qualms with equities at times, but overall, they are more palatable than the fixed income portion of the portfolio. I don’t like it either, but the money is broken and the unit of account for nearly every equity or fixed income instrument (USD) is fraudulent. It’s a paper mache fade that is quite literally propped up by the money printer.
To briefly be as most charitable as I can – It wasn’t always this way. The U.S. Dollar used to be sound money, we used to have government surplus instead of mathematically certain deficits, The U.S. Federal Government didn’t used to have a money printing addiction, and pre-bitcoin the 60/40 portfolio used to be a quality portfolio management strategy. Those times are gone.
Now the fun part. How does bitcoin fix this?
Bitcoin fixes this indirectly. Understanding investment criteria changes via risk tolerance, age, goals, etc. A client may still have a need for “fixed income” in the most literal definition – Low risk yield. Now you may be thinking that yield is a bad word in bitcoin land, you’re not wrong, so stay with me. Perpetual motion machine crypto yield is fake and largely where many crypto scams originate. However, that doesn’t mean yield in the classic finance sense does not exist in bitcoin, it very literally does. Fortunately for us bitcoiners there are many other smart, driven, and enterprising bitcoiners that understand this problem and are doing something to address it. These individuals are pioneering new possibilities in bitcoin and finance, specifically when it comes to fixed income.
Here are some new developments –
Private Credit Funds – The Build Asset Management Secured Income Fund I is a private credit fund created by Build Asset Management. This fund primarily invests in bitcoin-backed, collateralized business loans originated by Unchained, with a secured structure involving a multi-signature, over-collateralized setup for risk management. Unchained originates loans and sells them to Build, which pools them into the fund, enabling investors to share in the interest income.
Dynamics
- Loan Terms: Unchained issues loans at interest rates around 14%, secured with a 2/3 multi-signature vault backed by a 40% loan-to-value (LTV) ratio.
- Fund Mechanics: Build buys these loans from Unchained, thus providing liquidity to Unchained for further loan originations, while Build manages interest payments to investors in the fund.
Pros
- The fund offers a unique way to earn income via bitcoin-collateralized debt, with protection against rehypothecation and strong security measures, making it attractive for investors seeking exposure to fixed income with bitcoin.
Cons
- The fund is only available to accredited investors, which is a regulatory standard for private credit funds like this.
Corporate Bonds – MicroStrategy Inc. (MSTR), a business intelligence company, has leveraged its corporate structure to issue bonds specifically to acquire bitcoin as a reserve asset. This approach allows investors to indirectly gain exposure to bitcoin’s potential upside while receiving interest payments on their bond investments. Some other publicly traded companies have also adopted this strategy, but for the sake of this article we will focus on MSTR as they are the biggest and most vocal issuer.
Dynamics
-
Issuance: MicroStrategy has issued senior secured notes in multiple offerings, with terms allowing the company to use the proceeds to purchase bitcoin.
-
Interest Rates: The bonds typically carry high-yield interest rates, averaging around 6-8% APR, depending on the specific issuance and market conditions at the time of issuance.
-
Maturity: The bonds have varying maturities, with most structured for multi-year terms, offering investors medium-term exposure to bitcoin’s value trajectory through MicroStrategy’s holdings.
Pros
-
Indirect Bitcoin exposure with income provides a unique opportunity for investors seeking income from bitcoin-backed debt.
-
Bonds issued by MicroStrategy offer relatively high interest rates, appealing for fixed-income investors attracted to the higher risk/reward scenarios.
Cons
-
There are credit risks tied to MicroStrategy’s financial health and bitcoin’s performance. A significant drop in bitcoin prices could strain the company’s ability to service debt, increasing credit risk.
-
Availability: These bonds are primarily accessible to institutional investors and accredited investors, limiting availability for retail investors.
Interest Payable in Bitcoin – River has introduced an innovative product, bitcoin Interest on Cash, allowing clients to earn interest on their U.S. dollar deposits, with the interest paid in bitcoin.
Dynamics
-
Interest Payment: Clients earn an annual interest rate of 3.8% on their cash deposits. The accrued interest is converted to Bitcoin daily and paid out monthly, enabling clients to accumulate Bitcoin over time.
-
Security and Accessibility: Cash deposits are insured up to $250,000 through River’s banking partner, Lead Bank, a member of the FDIC. All Bitcoin holdings are maintained in full reserve custody, ensuring that client assets are not lent or leveraged.
Pros
-
There are no hidden fees or minimum balance requirements, and clients can withdraw their cash at any time.
-
The 3.8% interest rate provides a predictable income stream, akin to traditional fixed-income investments.
Cons
-
While the interest rate is fixed, the value of the Bitcoin received as interest can fluctuate, introducing potential variability in the investment’s overall return.
-
Interest rate payments are on the lower side
Admittedly, this is a very small list, however, these types of investments are growing more numerous and meaningful. The reality is the existing options aren’t numerous enough to service every client that has a need for fixed income exposure. I challenge advisors to explore innovative options for fixed income exposure outside of sovereign debt, as that is most certainly a road to nowhere. It is my wholehearted belief and call to action that we need more options to help clients across the risk and capital allocation spectrum access a sound money standard.

2025-03-21 19:41:50Wir werden nicht zulassen, dass technisch manches möglich ist, \ aber der Staat es nicht nutzt. \ Angela Merkel
Die Modalverben zu erklären, ist im Deutschunterricht manchmal nicht ganz einfach. Nicht alle Fremdsprachen unterscheiden zum Beispiel bei der Frage nach einer Möglichkeit gleichermaßen zwischen «können» im Sinne von «die Gelegenheit, Kenntnis oder Fähigkeit haben» und «dürfen» als «die Erlaubnis oder Berechtigung haben». Das spanische Wort «poder» etwa steht für beides.
Ebenso ist vielen Schülern auf den ersten Blick nicht recht klar, dass das logische Gegenteil von «müssen» nicht unbedingt «nicht müssen» ist, sondern vielmehr «nicht dürfen». An den Verkehrsschildern lässt sich so etwas meistens recht gut erklären: Manchmal muss man abbiegen, aber manchmal darf man eben nicht.
Dieses Beispiel soll ein wenig die Verwirrungstaktik veranschaulichen, die in der Politik gerne verwendet wird, um unpopuläre oder restriktive Maßnahmen Stück für Stück einzuführen. Zuerst ist etwas einfach innovativ und bringt viele Vorteile. Vor allem ist es freiwillig, jeder kann selber entscheiden, niemand muss mitmachen. Später kann man zunehmend weniger Alternativen wählen, weil sie verschwinden, und irgendwann verwandelt sich alles andere in «nicht dürfen» – die Maßnahme ist obligatorisch.
Um die Durchsetzung derartiger Initiativen strategisch zu unterstützen und nett zu verpacken, gibt es Lobbyisten, gerne auch NGOs genannt. Dass das «NG» am Anfang dieser Abkürzung übersetzt «Nicht-Regierungs-» bedeutet, ist ein Anachronismus. Das war vielleicht früher einmal so, heute ist eher das Gegenteil gemeint.
In unserer modernen Zeit wird enorm viel Lobbyarbeit für die Digitalisierung praktisch sämtlicher Lebensbereiche aufgewendet. Was das auf dem Sektor der Mobilität bedeuten kann, haben wir diese Woche anhand aktueller Entwicklungen in Spanien beleuchtet. Begründet teilweise mit Vorgaben der Europäischen Union arbeitet man dort fleißig an einer «neuen Mobilität», basierend auf «intelligenter» technologischer Infrastruktur. Derartige Anwandlungen wurden auch schon als «Technofeudalismus» angeprangert.
Nationale Zugangspunkte für Mobilitätsdaten im Sinne der EU gibt es nicht nur in allen Mitgliedsländern, sondern auch in der Schweiz und in Großbritannien. Das Vereinigte Königreich beteiligt sich darüber hinaus an anderen EU-Projekten für digitale Überwachungs- und Kontrollmaßnahmen, wie dem biometrischen Identifizierungssystem für «nachhaltigen Verkehr und Tourismus».
Natürlich marschiert auch Deutschland stracks und euphorisch in Richtung digitaler Zukunft. Ohne vernetzte Mobilität und einen «verlässlichen Zugang zu Daten, einschließlich Echtzeitdaten» komme man in der Verkehrsplanung und -steuerung nicht aus, erklärt die Regierung. Der Interessenverband der IT-Dienstleister Bitkom will «die digitale Transformation der deutschen Wirtschaft und Verwaltung vorantreiben». Dazu bewirbt er unter anderem die Konzepte Smart City, Smart Region und Smart Country und behauptet, deutsche Großstädte «setzen bei Mobilität voll auf Digitalisierung».
Es steht zu befürchten, dass das umfassende Sammeln, Verarbeiten und Vernetzen von Daten, das angeblich die Menschen unterstützen soll (und theoretisch ja auch könnte), eher dazu benutzt wird, sie zu kontrollieren und zu manipulieren. Je elektrischer und digitaler unsere Umgebung wird, desto größer sind diese Möglichkeiten. Im Ergebnis könnten solche Prozesse den Bürger nicht nur einschränken oder überflüssig machen, sondern in mancherlei Hinsicht regelrecht abschalten. Eine gesunde Skepsis ist also geboten.

🔐 1. SHA-256 is Quantum-Resistant
Bitcoin’s proof-of-work mechanism relies on SHA-256, a hashing algorithm. Even with a powerful quantum computer, SHA-256 remains secure because:
- Quantum computers excel at factoring large numbers (Shor’s Algorithm).
- However, SHA-256 is a one-way function, meaning there's no known quantum algorithm that can efficiently reverse it.
- Grover’s Algorithm (which theoretically speeds up brute force attacks) would still require 2¹²⁸ operations to break SHA-256 – far beyond practical reach.
++++++++++++++++++++++++++++++++++++++++++++++++++
🔑 2. Public Key Vulnerability – But Only If You Reuse Addresses
Bitcoin uses Elliptic Curve Digital Signature Algorithm (ECDSA) to generate keys.
- A quantum computer could use Shor’s Algorithm to break SECP256K1, the curve Bitcoin uses.
- If you never reuse addresses, it is an additional security element
- 🔑 1. Bitcoin Addresses Are NOT Public Keys
Many people assume a Bitcoin address is the public key—this is wrong.
- When you receive Bitcoin, it is sent to a hashed public key (the Bitcoin address).
- The actual public key is never exposed because it is the Bitcoin Adress who addresses the Public Key which never reveals the creation of a public key by a spend
- Bitcoin uses Pay-to-Public-Key-Hash (P2PKH) or newer methods like Pay-to-Witness-Public-Key-Hash (P2WPKH), which add extra layers of security.
🕵️♂️ 2.1 The Public Key Never Appears
- When you send Bitcoin, your wallet creates a digital signature.
- This signature uses the private key to prove ownership.
- The Bitcoin address is revealed and creates the Public Key
- The public key remains hidden inside the Bitcoin script and Merkle tree.
This means: ✔ The public key is never exposed. ✔ Quantum attackers have nothing to target, attacking a Bitcoin Address is a zero value game.
+++++++++++++++++++++++++++++++++++++++++++++++++
🔄 3. Bitcoin Can Upgrade
Even if quantum computers eventually become a real threat:
- Bitcoin developers can upgrade to quantum-safe cryptography (e.g., lattice-based cryptography or post-quantum signatures like Dilithium).
- Bitcoin’s decentralized nature ensures a network-wide soft fork or hard fork could transition to quantum-resistant keys.
++++++++++++++++++++++++++++++++++++++++++++++++++
⏳ 4. The 10-Minute Block Rule as a Security Feature
- Bitcoin’s network operates on a 10-minute block interval, meaning:Even if an attacker had immense computational power (like a quantum computer), they could only attempt an attack every 10 minutes.Unlike traditional encryption, where a hacker could continuously brute-force keys, Bitcoin’s system resets the challenge with every new block.This limits the window of opportunity for quantum attacks.
🎯 5. Quantum Attack Needs to Solve a Block in Real-Time
- A quantum attacker must solve the cryptographic puzzle (Proof of Work) in under 10 minutes.
- The problem? Any slight error changes the hash completely, meaning:If the quantum computer makes a mistake (even 0.0001% probability), the entire attack fails.Quantum decoherence (loss of qubit stability) makes error correction a massive challenge.The computational cost of recovering from an incorrect hash is still incredibly high.
⚡ 6. Network Resilience – Even if a Block Is Hacked
- Even if a quantum computer somehow solved a block instantly:The network would quickly recognize and reject invalid transactions.Other miners would continue mining under normal cryptographic rules.51% Attack? The attacker would need to consistently beat the entire Bitcoin network, which is not sustainable.
🔄 7. The Logarithmic Difficulty Adjustment Neutralizes Threats
- Bitcoin adjusts mining difficulty every 2016 blocks (\~2 weeks).
- If quantum miners appeared and suddenly started solving blocks too quickly, the difficulty would adjust upward, making attacks significantly harder.
- This self-correcting mechanism ensures that even quantum computers wouldn't easily overpower the network.
🔥 Final Verdict: Quantum Computers Are Too Slow for Bitcoin
✔ The 10-minute rule limits attack frequency – quantum computers can’t keep up.
✔ Any slight miscalculation ruins the attack, resetting all progress.
✔ Bitcoin’s difficulty adjustment would react, neutralizing quantum advantages.
Even if quantum computers reach their theoretical potential, Bitcoin’s game theory and design make it incredibly resistant. 🚀

2024-09-06 12:49:46Nostr: a quick introduction, attempt #2
Nostr doesn't subscribe to any ideals of "free speech" as these belong to the realm of politics and assume a big powerful government that enforces a common ruleupon everybody else.
Nostr instead is much simpler, it simply says that servers are private property and establishes a generalized framework for people to connect to all these servers, creating a true free market in the process. In other words, Nostr is the public road that each market participant can use to build their own store or visit others and use their services.
(Of course a road is never truly public, in normal cases it's ran by the government, in this case it relies upon the previous existence of the internet with all its quirks and chaos plus a hand of government control, but none of that matters for this explanation).
More concretely speaking, Nostr is just a set of definitions of the formats of the data that can be passed between participants and their expected order, i.e. messages between clients (i.e. the program that runs on a user computer) and relays (i.e. the program that runs on a publicly accessible computer, a "server", generally with a domain-name associated) over a type of TCP connection (WebSocket) with cryptographic signatures. This is what is called a "protocol" in this context, and upon that simple base multiple kinds of sub-protocols can be added, like a protocol for "public-square style microblogging", "semi-closed group chat" or, I don't know, "recipe sharing and feedback".

18.12.2024 / Autor: Ana Nives Radović
Ako ste makar djelić vremena proveli u svijetu digitalnog novca, vjerovatno ste naišli na termin HODL – uvijek napisan velikim slovima tako da na prvi pogled djeluje kao riječ sa slovnom greškom. Zapravo i jeste riječ o slovnoj grešci i to onoj koja je nastala na današnji dan prije 11 godina, a koja je uspjela ne samo da obezbijedi mjesto u istoriji svijeta novca, već i da postane naziv za jedan potpuno drugačiji pristup sredstvima koja posjedujemo.
Nespretno napisana riječ „hold“ (eng. držati, zadržati) u poruci na jednom forumu evoluirala je u akronim HODL – akronim za Hold On for Dear Life (doslovno – drži se za život, tj. drži se kao da ti život zavisi od toga), predstavlja poziv na akciju – ili, tačnije, „neakciju“ za vlasnike kriptovaluta da odole iskušenju prodaje tokom tržišnih padova. Riječ je o shvatanju da je ovaj oblik digitalne imovine bolje vremenski što duže imati u vlasništvu, kako bi se sačekao mnogo povoljniji trenutak za prodaju nego prodati ih u vremenu kada je situacija na tržištu loša.
Greška koja je postala pokret
Priča počinje 18. decembra 2013. godine, kada je cijena bitcoina tada počela da pada, a samo tokom toga dana se sa 682 na 522 dolara. Korisnik foruma pod imenom GameKyuubi objavio je sada već legendarni post pod naslovom „I AM HODLING“. Bila je to greška u kucanju, jer se na osnovu sadržaja poruke vidi da je krenuo da napiše „holding“ (držim), ali umjesto da se ispravi sebe, prigrlio je grešku, šaljivo govoreći o svom nedostatku vještina za trgovanje i zašto „bez obzira na sve“.
Bitcoin zajednica brzo je prihvatila ovaj izraz kao dio slenga. Pogrešno napisana riječ odjeknula je internet prostranstvima, a vremenom je prerasla u simbol šire filozofije – ne paniči, ne prodaj i ne dozvoli da kratkoročna nestabilnost poljulja tvoje uvjerenje. Od kasnonoćnog posta na forumu, HODL je postao poklič za vlasnike bitcoina (i drugih, u to vrijeme malobrojnih digitalnih valuta zanemarive vrijednosti) širom svijeta.
HODL-ovanje i HODL-eri
U suštini, HODL-ovanje je strategija zadržavanja kriptovaluta tokom tržišnih uspona i padova, zasnovana na uvjerenju da će cijene vremenom rasti. Umjesto impulsivnog reagovanja na tržišne fluktuacije, HODL-eri se posvećuju svojim investicijama na duže staze.
Ovaj pristup posebno je koristan za početnike, koji možda nemaju dovoljno stručnosti ili hrabrosti da se nose sa svakodnevnim trgovanjem (u čemu su često neuspješni i dugogodišnji vlasnici digitalnih novčića). Sam GameKyuubi u svom originalnom postu priznao je da samo najvještiji trgovci treba da pokušaju da „igraju igru“ tokom tržišnih padova. Za ostale, HODL-ovanje nije samo sigurnije, već je često i pametnije.
Filozofija HODL-ovanja zasnovana je na povjerenju – u budućnost kriptovaluta, u eventualni oporavak tržišta i u korist koju donosi strpljenje. To je odbijanje da se prodaje kada cijene naglo padnu – nepokolebljivo uvjerenje da su padovi privremeni i da nakon njih slijedi rast.
Zakon tržišta pokazuje da što drže HODL-ujete to se ova strategija više isplati, a cijena bitcoina u njegovoj šesnaestogodišnjoj istoriji je nesumnjivo najbolji dokaz za to. Trgovanje zahtijeva mnogo učenja, truda, vremena provedenog u praćenju svakog mogućeg signala, dok je kod HODL-ovanja važno samo da se „ne predate“.
Ako ste prethodnih godina nešto platili bitcoinom (a trgovci širom svijeta su to omogućili upravo da bi vas naveli da ih umjerite ka njima) vjerovatno ste zažalili, jer danas dok je njegova vrijednost i u dolarima i u eurima šestocifrena, ono na što ste ih potrošili ipak izgleda kao nešto što je trebalo platiti fizičkim novcem (kojeg je svakako „pojela inflacija“).
Pouzdane kriptovalute, a tu se prije svega misli na bitcoin, iako veoma volatilne bilježe trend rasta na duge staze, pa HODL-ovanje znači strpljenje u vremenu neizvjesnosti s idejom o koristi na duži rok, čak i kada su godine loše, kao što su bile 2014, 2017. i 2022. Na primjer, u periodu od 20. maja do 20. juna cijena bitcoina kliznula je sa 29.000 na 18.000 dolara, a upravo u tom trenutku mnogi su odlučili da količinu koju posjeduju prodaju ili je potroše plaćajući ovom digitalnom valutom (i pokajali se zbog toga).
HODL naspram drugih strategija
HODL-ovanje se razlikuje od aktivnijih strategija, poput kupovine po niskoj cijeni i prodaje po visokoj, jer dok trgovci pokušavaju da tempiraju tržište radi brze zarade, HODL-eri ostaju dosljedni svojoj odluci da se ne oslobađaju svoje imovine ni u najnoepovoljnijim trenucima. HODL-eri ne pokušavaju da predvide kretanje cijena – jednostavno čuvaju svoja sredstva, svjesni toga da će strpljenje na kraju donijeti rezultat.
Naravno, HODL-ovanje ima i svoje nedostatke. Za razliku od trgovaca koji mogu da povećaju svoj kapital kroz stratešku kupovinu i prodaju, HODL-eri zavise od vremena provedenog u čekanju na dugoročne rezultate. Pored toga, masovno HODL-ovanje može usporiti cirkulaciju kriptovaluta na tržištu, smanjujući ukupnu ekonomsku aktivnost – drugim riječima, kada bismo svi bili HODL-eri odnos ponude i tražnje bi bio veoma destimulišući i to bi oborilo cijenu.
Na sreću, trgovaca ima mnogo – dovoljno da tržište stalno bude aktivno i dinamično, no za one koji nemaju vremena, vještine ili sklonost ka riziku koji nosi trgovanje, HODL-ovanje ostaje jednostavan, ali veoma efikasan pristup.
Filozofija HODL-ovanja
HODL-ovanje je više od investicione strategije – to je način razmišljanja koji obuhvata otpornost, strpljenje i vjerovanje da su kratkotrajno suzdržavanje i nepokolebljivost u odluci da se sredstva sačuvaju vrijedna dugoročnog dobitka. Bilo da cijena bitcoina raste ili pada je, filozofija HODL-ovanja ostaje ista – ostanimo dosljedni, vjerujmo procesu i gledajmo u budućnost.
Jedan od ključnih razloga zašto većini ljudi ovakav pristup dugo nije bio razumljiv je zbog toga što su čitav sistem novca prihvatili u uvjerenju da on vremenom devalvira. Vjerovatno ste makar jednom razmatrali ponudu oročene štednje i procijenili da vam količina novca koju želite da položite neće donijeti onaj prinos koji će očuvati njegovu kupovnu moć nakon određenog broja godina, jer je kontinuirano doštampavanje novca podupiralo tu tvrdnju.
Dakle, ne treba da vas zavara sve ono što znate o novcu kao takvom, budući da bitcoin (na kojem je u ovom serijalu poseban fokus, jer mnoge druge kriptovalute ipak češće razočaraju nego što oduševe) nije novac, već samo ima neka svojstva novca. Posmatrajte ga radije kao imovinu – npr. kao nekretninu za koju sigurno želite da prodate onda kada je situacija stabilnija i kada su mnogo veće šanse da pronađete kupca kojem ćete je prodati po višoj cijeni.
U svakom slučaju, ako se u vašem digitalnom novčaniku već nalazi poneki satoshi (stomilioniti djelić bitcoina), kada tržište ponovo uđe u nepovoljnu fazu i zavlada prolazna panika, sjetite se onoga što je napisao GameKyuubi. HODL nije samo izraz – to je način da se prebrode oluje i izazovi koje nestabilno tržište nosi.

Kriptovalute (engl. "cryptocurrency") su digitalne (virtualne) valute, koje iako su sredstvo razmene, još uvek nisu strogo regulisane zakonom u većini država, a u pojedinim su čak i zabranjene. Veliki broj ljudi, uključujući i IT stručnjake i programere ne znaju mnogo o ovoj temi, a šira javnost izjednačava pojmove blokčejna i bitkoina. Tržište kriptovaluta danas iznosi gotovo 770 milijardi dolara. Od pojave prvih digitalnih valuta do danas, nastalo je preko 1.300 aktivnih kriptovaluta koje se razlikuju prema svojim svojstvima i upotrebi. Pre bitkoina bilo je mnoštvo neuspelih pokušaja stvaranja digitalnih valuta (digikeš, heškeš, Fejsbuk kredit i dr.). Utopistička ideja da matematika i fizika mogu rešiti društvene probleme započela je svoj život kroz pojavu bitkoina. Genijalna ideja po kojoj funkcioniše bitkoin zasnovana je na tehnologiji blokčejna, čiji kapacitet doseže daleko iznad kripto valuta. Iako se još uvek vode polemike ko stoji iza pseudonima Satoši Nakamoto, njegova zaostavština ima potencijal da promeni svet. Uspeh bitkoina leži u prednostima koje ima u odnosu na druge slične valute, ali njegov značaj prevazilazi i pogodnosti koje je doneo. Banke nisu potrebne za čuvanje podataka o novcu, evidenciju o imovini i svakoj transakciji bitkoina čuvaju računari svih korisnika mreže u zajedničkoj bazi podataka blokčejnu. Sve transakcije su mnogo brže od bankarskih, bez taksi, uz drastično lakše plaćanje preko državnih granica. Bitkoin svojim korisnicima pruža bezbednosti bez identifikacije, iako blokčejn beleži transakciju, ne beleži ko stoji iza nje. U radu su predstavljeni osnovni principi na kojima su zasnovani bitkoin i druge kriptovalute, pojašnjen odnos između blokčejna i bitkoina.
1 UVOD
Ideal o novcu koji se ne oslanja na centralne institucije (koje mogu propasti, ali i koje vrše nadzor nad korisnicima), postojao je decenijama. U digitalnom svetu prvi ga je uobličio pisac naučne fantastike Nil Stivenson 1999. godine u svojoj noveli Kriptonomikon. On je opisao podzemni svet koji funkcioniše zahvaljujući digitalnom zlatu zasnovanom na kriptografiji, pri čijoj upotrebi korisnici ne moraju odavati ko su i šta su (Popper, 2016).
Kriptovalute (engl. cryptocurrency) su digitalne (virtualne) valute, koje iako su sredstvo razmene, još uvek nisu strogo regulisane zakonom u većini država, a u pojedinim su čak i zabranjene (Jovanović, 2014).
Da bi se razumeo nastanak i funkcionisanje kriptovaluta, neophodno je sagledati ih iz različitih uglova na kojima su one bazirane: matematici, sociologiji, ekonomiji, pravu i politici. To je verovatno i glavni razlog zbog koga veliki broj ljudi (uključujući i IT stručnjake i programere) ne znaju mnogo o ovoj temi. Takođe, šira javnost izjednačava pojmove blokčejna i bitkoina.
Sve kriptovalute su bazirane na jedinstvenom nizu brojeva za svaku jedinicu valute, koje korisnici mogu jedni drugima slati preko mreže. U prošlosti su se ti nizovi mogli lako kopirati i trošiti više puta, zbog čega nisu imali vrednost. Kriptograf Dejvid Čaum je taj problem rešio stvaranjem jedinstvene centralizovane knjige, u kojoj su se čuvale beleške o transakcijama svakog korisnika, čime ni jedna jedinica valute više nije mogla da se nalazi na dva mesta istovremeno (Bertlet, 2016).
Kriptovalute svoj nastanak duguju težnjama levo orijentisanih utopističkih posvećenika IT tehnologija koji su sanjali o univerzalnom novcu koji bi svako mogao da poseduje i troši, čija je vrednost onolika koliko su korisnici voljni da plate (na principu ponude i potražnje), ali pre svega na liniji fronta za onlajn anonimnost i slobodu, bez cenzure i nadzora. Pojavi bitkoina prethodio je Sajberpankerski manifest Done Haravej (Haraway, 1985) koji počinje rečima: „U elektronsko doba, privatnost je neophodan uslov za postojanje otvorenog društva“.
Kriptovalute su univerzalni novac koji se može koristiiti bilo gde u svetu, one su lako prenosive i teško se krivotvore.
Neki podaci pokazuju da tržište kriptovaluta danas iznosi gotovo 770 milijardi dolara. Od pojave prvih digitalnih valuta do danas, nastalo je preko 1.300 aktivnih kriptovaluta koje se razlikuju prema svojim svojstvima i upotrebi.
Prema odredbama Zakona o Narodnoj banci Srbije celokupni unutrašnji promet u Republici Srbiji izražava se u dinarima, osim ako nekim zakonom nije drukčije određeno. „Zakonom o platnom prometu propisano je da se poslovi platnog prometa obavljaju u dinarima, a Zakonom o deviznom poslovanju da se plaćanje, naplaćivanje i prenos između rezidenata i između rezidenata i nerezidenata u Republici Srbiji vrši u dinarima, a izuzetno se može vršiti i u devizama u slučajevima koji su propisani ovim zakonom“ (NBS, 2014).
Tržište kriptovaluta u Srbiji postoji, sve je veći broj rudara. Iako trgovanje kriptovalutama nije nelegalno, Narodna Banka Srbije - NBS je u više saopštenja navela da one ne predstavljaju zakonsko sredstvo plaćanja u Republici Srbiji. Takođe, zbog toga što ih ne izdaje centralna banka, NBS za korišćenje virtuelnih valuta, ulaganje u njih, kao ni za njihovu vrednost. Narodna banka Srbije je više puta upozoravala javnost da virtuelne valute ne predstavljaju zakonsko sredstvo plaćanja u Republici Srbiji (NBS, Politika – u vezi s bitkoinom, 2017).
Ukoliko kriptovalute promatramo kao novac onda njihove tranksakcije mogu biti upitne shodno Zakonu o sprečavanju pranja novca i finansiranja terorizma, gde je propisana obaveza preduzimanja radnji i mera za sprečavanje pranja novca, kao što su identifikacija stranaka koje trguju preko tih platformi, uzimanjem kopije ličnog dokumenta. Kako poslovanje platformi na kojima se vrše transakcije kriptovalutama nije zakonom regulisano u Republici Srbiji, a uglavnom ni u uporednom pravu, a čl. 552. Zakona o obligacionim odnosima Republike Srbije ((„Sl. list SFRJ“, br. 29/78, 39/85, 45/89 - odluka USJ i 57/89, „Sl. list SRJ“, br. 31/93 i „Sl. list SCG“, br. 1/2003 - Ustavna povelja) predviđa razmenu robe kao jedan od načina trgovine, otvara se put ka legalnoj trgovini kriptovalutama (Bubanja, 2017).
Praksa je pokazala da su se korisnici kriptovaluta kada su imali problem sa njima, obraćali vlastima i njihovim regulatornim telima, zbog čijeg su zaobilaženja i smišljeni. Nažalost, korisnici ne uživaju pravnu zaštitu čak i kada je reč o trgovini putem registrovanih privrednih subjekta.
2 BITKOIN
Prva decentralizovana kriptovaluta koja se pojavila je bitkoin (eng. „Bitcoin“). Termin bitkoin označava istoimenu organizaciju, softver i protokol, kao i jedinicu mere ove kriptovalute (skraćeno BTC) (Bertlet, 2016). Koncept na kome se zasniva bitkoin prvi put je predstavljen 2008. godine u članku "Bitcoin: A Peerto-Peer Electronic Cash System", a u januaru 2009. godine bitkoin je pušten u promet. Njegov tvorac nije poznat do danas i krije se iza pseudonima Satoši Nakomato. Novu vrstu digitalne kriptovalute formirao je tako što je stvorio distribuirani sistem verifikacije. Bitkoin nastaje u procesu koji se naziva „rudarenje“ (engl. mining). Njegova jedinstvenost je u tome što je decentralizovana valuta, iza koje ne stoji nijedna država, niti banka. Bitkoin je digitalna valuta, koja nastaje i čuva se elektronski. Kriptovalute u cilju maksimizacije bezbednosti, upotrebljavaju metod - dokaz o radu (engl. proofof-work), metod baziran na informacijama koje je teško stvoriti, ali koje ostalim učesnicima u rudarenju obezbeđuju laku proveru i verifikaciju transakcija.
Kriptovalute se čuvaju na bitkoin adresama za koje ključ predstavlja jedinstven niz slova i brojeva. Svaka transkacija bitkoinom se beleži u blokovima koji se zovu blokčejn. Transakcije se hronološki ređaju u blokove, u svakom se nalazi digitalni potpis prethodnog bloka, time se uređuje redosled i garantuje da novi blok može da se pridruži lancu samo ako počne na mestu na mestu završetka prethodnog. Jedan od osnovnih činilaca bezbednosti bitkoina je da se kopija svake izvedene transakcije beleži na svakom nalogu na kome je instaliran bitkoin softver. Blokčejnove neprekidno verifikuju računari svih korisnika softvera, tako sistem zna u bilo kom trenutku, koliko bitkoina svaki korisnik u svom novčaniku poseduje. Novčanik je program koji služi za slanje, primanje i skladištenje kriptovaluta. Digitalni novčanik sadrži prikaz količine kriptovalute koju korisnik poseduje, zapise o svim njegovim transakcijama, korisnički tajni ključ i njegove adrese (Bertlet, 2016). Novčanik je moguće instalirati na računar, mobilni telefon i tablet.
Falsifikovanje bitkoina nije moguće, jer iako vlasništvo može da se menja ono se ne može nikada duplirati (Bertlet, 2016). On je pseudoanoniman, bitkoin mreža čuva sve podatke o svakoj transakciji koja se dogodila unutar mreže. Svako ko ima bitkoin softver i adresu na bitkoin mreži, može videti koliko novca ima na mreži, ali ne i kome oni pripadaju. Za razliku od otvaranja računa u bankama, otvaranje bitkoin računa (adrese) je brzo, bez troškova i „papirologije“. Jedna od glavnih prednosti bitkoin mreže je brzina transakcija.
Svako ko snagu svog računara posveti verifikaciji transakcija u blokčejnu može biti „rudar“. To je proces dodavanja transkacija u registar svih bitkoin transkacija. Rudarenje čini rešavanje matematičkog algoritma za čije se uspešno rešavanje dobija određena količina bitkoina.
Iako bitkoin ima reputaciju nestabilnosti, velikih fluktuacija i nezakonitog poslovanja, čemu mnogi pridodaju i urušavanje tradicionalnog koncepta nacionalnih država, ipak većina se slaže u tome da je njegova pojava najvažnija nova ideja od stvaranja Interneta (Vigna & Casey, 2016).
Razloga za uspeh bitkoina ima više. Finansijska kriza povoljno je uticala na njegov razvoj, poverenje u postojeći finansijski ali i politički sistem je bilo poljuljano i brojni korisnici su u njemu prepoznali drugačije rešenje.
Anonimnost koju pruža prilikom transakcija jedan je od ključnih razloga njegovog uspeha. Prilikom digitalnog plaćanja bitkoinom u većini slučajeva nije potrebno davanje ličnih podataka. Ovakva vrsta anonimnosti, nažalost pogodovala je i usponu tamne strane upotrebe i popularnosti bitkoina u kriminalnim krugovima.
Računi u bitkoinu nisu opterećeni visokim bankarskim dažbinama.
Takođe, nije beznačajan ni potencijal plaćanja izdataka koji su manji od trenutnih ograničenja u konvencijalnim transakcijama na internetu (npr. naplata čitanja jednog novinskog članka ili preskoči reklamu, koji koštaju manje od 20 ili 30 centi kolika je najmanja transakcija) (Popper, 2016).
Kao što su svi učesnici na internetu povezani protokolima (TCP/IP, FTP, SMTP, HTTP i dr.) zahvaljujući kojima mogu međusobno da komuniciraju, bitkoin je stvorio svoje softverske protokole koji uređuju funkcionalna pravila upravljanja sistemom.
Bitkoin je omogućio novi način stvaranja, čuvanja i transfera novca.
Od svog nastanka bitkoin se unapređivao, podržan od internet zajednice, posebno od posvećenika slobodi interneta i anonimosti, mnogi od problema koji su uočeni su rešavani zajedničkim naporom internet zajednice.
3 BLOKČEJN
Blokčejn (engl. blockchain) nije samo bitkoin, on je tehnologija za koju mnogi predviđaju da će promeni svet (OECD, 2018).
Ukoliko bismo pojednostavljeno opisivali blokčejn mogli bismo da kažemo da je to nova vrsta baze podataka, iako bi to bilo pojednostavljeno objašnjenje slično kao kada bi smo imejl (email) opisali kao novi način za slanje pisama.
Iako blokčejn jeste nova vrsta baze podatka, to ne objašnjava u dovoljnoj meri genijalnost načina na koji funkcioniše.
Kada bilo gde i bilo kada položimo novac, oslanjamo se na zapis u bazi podataka treće strane, banke, firme i sl. Poverenje u banke zasnovano je na zakonu koji reguliše rad banke, poverenju u državu da će u slučaju propasti banke država nadoknaditi klijentima njihov ulog.
Kada plaćamo on line usluge ili vršimo neku drugu transakciju kreditnim karticama, poklanjamo poverenje kompanijama koje posreduju u našem plaćanju (Mastercard, VISA i dr.) koje za to uzimaju određenu materijalnu nadoknadu. Čak i prilikom tradicionalnih oblika plaćanja gotovinom u papirnom novcu, mi dajemo papir na kome je ispisana vrednost za koju prodavac veruje da će mu biti isplaćena (ili garantovana) od strane vlade koja ju je štampala. Digitalno plaćanje zbog prisustva trećih strana (banke, kreditne kompanije i dr.) uvek je bilo moguće pratiti. I kod plaćanja gotovinom klijenti veruju bankama i kreditnim kompanijama koje rukovode platnim karticama, da imaju pouzdane baze podataka. I vlade država veruju da banke i kreditne kompanije vode baze podataka koje su tačne i pouzdane.
Baze podataka sadrže mnoštvo ličnih podataka, od npr. medicinske dokumentacije u domu zdravlja koja sadrži važne informacije o nama i našem zdravstvenom stanju, kada smo i od koje bolesti bolovali, koje lekove smo koristili i sl. I druge baze podataka sadrže mnoštvo naših ličnih podataka koje su važne ne samo za nas, već i za državu, grad, privredu, druge građane itd.
Osim što omogućava anonimne i sigurne transakcije, blokčejn ima i potencijal da sačuva sve vredne informacije, od podataka o rođenim i umrlim, preko osiguranja, do katastara nepokretnosti, pa čak i glasova (Tapscott, 2018).
Sagledavši mogućnosti koji blokčejn nudi u transformaciji industrija i tržišta, povećanju transparentnosti i poverenja između građana, kao i olakšanom pristupu tržištu (uz bolju efikasnost transakcija), ali i rizicima koje sa sobom nosi, Organizacija za ekonomsku saradnju i razvoj - OECD organizovala je od 4. do 5. septembra 2018. godine Forum politike OECD-a za blokčejn. To je bila ujedno i prva glavna međunarodna konferencija na kojoj se razmatrao uticaj blokčejna na aktivnosti vlada i javnih prioriteta. Forum se bavio prednostima i rizicima blokčejna za ekonomiju i društvo, pokušajem određivanja adekvatnog regulatornog pristupa, kao i javnih politika prema blokčejnu.
Učesnici Foruma su diskutovali o mogućnostima globalnog ekonomskog uticaja blokčejna, njegovim implikacijama na privatnost i sajber bezbednost, upotrebi blokčejn tehnologija za povećanje inkluzivnosti, njegovoj upotrebi u promovisanju zelenog rasta i održivosti, kao i jačanju kapaciteta javne uprava i primene u praksi (OECD, 2018).
4 ZAKLJUČAK
Pre bitkoina bilo je mnoštvo neuspelih pokušaja stvaranja digitalnih valuta (digikeš, heškeš, Fejsbuk kredit i dr.). Uspeh bitkoina leži u prednostima koje ima u odnosu na druge slične valute, ali njegov značaj prevazilazi i pogodnosti koje je doneo.
Svaki korisnik bitkoina ima potpunu kontrolu nad novcem na svom računu (adresi), jedino osoba sa privatnim ključem može pristupiti bitkoinima na toj adresi. Banke nisu potrebne za čuvanje podataka o novcu, evidenciju o imovini i svakoj transakciji bitkoina čuvaju računari svih korisnika mreže u zajedničkoj bazi podataka blokčejnu. Sve transakcije su mnogo brže od bankarskih, bez taksi, uz drastično lakše plaćanje preko državnih granica.
Bitkoin svojim korisnicima pruža bezbednosti bez identifikacije, iako blokčejn beleži transakciju, ne beleži ko stoji iza nje. Zahvaljujući peer-to-peer komunikaciji i kriptografiji, povezivanje bitkoin transakcija sa osobom u stvarnom životu je veoma teško. To je u ujedno možda i njegova najveća mana, jer su oporezivanje i nadzor nad korisnicima krajnje teški.
Garancija vrednosti bitkoina osmišljena je po uzoru na plamenite metale kojih ima ograničeno u prirodi. Zbog toga je Satoši u kodu bitkoina odredio da ih ima maksimalno 21 milion, te da ukoliko bitkoin protokol ostane isti, poslednji bitkoin će biti izrudaren 2140. godine.
Do sada je izrudareno oko 17 miliona bitkoina, što znači da je ostalo 4 miliona, ili oko 19%. Do sada je bitkoin uspeo da prevlada sve krize koje su ga zahvatile (u više slučajeva nestajali su iznosi koji su dostizali i 400 miliona dolara). Kakva god sudbina bitkoina bila u budućnosti, njegova uloga se neće moći zanemariti, prvenstveno zbog toga što je zahvaljujući njemu iznedren blokčejn. Bez obzira na skepticima u vezi sa kriptovalutama, teško se mogu osporiti mogućnosti koje blokčejn pruža, pre svega u zaštiti baza podatka.

Postoji sveto carstvo privatnosti za svakog čoveka gde on bira i pravi odluke – carstvo stvoreno na bazičnim pravima i slobode koje zakon, generalno, ne sme narušavati. Džefri Fišer, Arhiepiskop Canterberija (1959)
Pre ne toliko dugo, uobičajen režim interneta je bio neenkriptovan običan tekst (plain text). Svi su mogli špiunirati svakoga i mnogi nisu o tome ni razmišljali. Globalno obelodanjivanje nadzora 2013. je to promenilo i danas se koriste mnogo bezbedniji protokoli i end-to-end enkripcija postaje standard sve više. Iako bitcoin postaje tinejdžer, mi smo – metaforično govoreći – i dalje u dobu običnog teksta narandžastog novčića. Bitcoin je radikalno providljiv protokol sam po sebi, ali postoje značajni načini da korisnik zaštiti svoju privatnost. U ovom članku želimo da istaknemo neke od ovih strategija, prodiskutujemo najbolje prakse, i damo preporuke koje mogu primeniti i bitcoin novajlije i veterani.
Zašto je privatnost bitna
Privatnost je potrebna da bi otvoreno društvo moglo da funkcioniše u digitalnoj eri. Privatnost nije isto što i tajanstvenost. Privatna stvar je nešto što neko ne želi da ceo svet zna, a tajna stvar je nešto što neko ne želi bilo ko da zna. Privatnost je moć da se čovek selektivno otkriva svom okruženju.
Ovim snažnim rečima Erik Hjus je započeo svoj tekst Sajferpankov Manifesto (Cypherpunk's Manifesto) 1993. Razlika između privatnosti i tajanstvenosti je suptilna ali jako važna. Odlučiti se za privatnost ne znači da neko ima tajne koje želi sakriti. Da ovo ilustrujemo shvatite samo da ono što obavljate u svom toaletu ili u spavaćoj sobi nije niti ilegalno niti tajna (u mnogim slučajevima), ali vi svejedno odlučujete da zatvorite vrata i navučete zavese.
Slično tome, koliko para imate i gde ih trošite nije naručito tajna stvar. Ipak, to bi trebalo biti privatan slučaj. Mnogi bi se složili da vaš šef ne treba da zna gde vi trošite vašu platu. Privatnosti je čak zaštićena od strane mnogobrojnih internacionalnih nadležnih organa. Iz Američke Deklaracije Prava i Dužnosti Čoveka (American Declaration of the Rights and Duties of Man) Ujedinjenim Nacijama, napisano je da je privatnost fundamentalno prava gradjana širom sveta.
Niko ne sme biti podvrgnut smetnjama njegovoj privatnosti, porodici, rezidenciji ili komunikacijama, niti napadnuta njegova čast i reputacija. Svi imaju pravo da se štite zakonom protiv takvih smetnja ili napada. Artikal 12, Deklaracija Ljudskih Prava Ujedinjenih Nacija
Bitcoin i privatnost
Iako je bitcoin često opisivan kao anoniman način plaćanja medijima, on u stvari poseduje potpuno suprotne osobine. On je poluanoniman u najboljem slučaju i danas mnogima nije ni malo lako primeniti taktike da bi bili sigurni da njihov poluanonimni identitet na bitcoin mreži ne bude povezan sa legalnim identitetom u stvarnom svetu.
Bitcoin je otvoren sistem. On je javna baza podataka koju svako može da proučava i analizira. Znači, svaka transakcija koja je upisana u tu bazu kroz dokaz rada (proof-of-work) postojaće i biće otkrivena dokle god bitcoin postoji, što znači - zauvek. Ne primenjivati najbolje prakse privatnosti može imati štetne posledice u dalekoj budućnosti.
Privatnost, kao sigurnost, je proces koji je težak, ali nije nemoguć. Alatke nastavljaju da se razvijaju koje čuvaju privatnost kad se koristi bitcoin and srećom mnoge od tih alatki su sve lakše za korišćenje. Nažalost ne postoji panacea u ovom pristupu. Mora se biti svesan svih kompromisa i usavršavati te prakse dok se one menjaju.
Najbolje prakse privatnosti
Kao i sve u bitcoinu, kontrola privatnosti je postepena, korak po korak, procedura. Naučiti i primeniti ove najbolje prakse zahteva strpljivost i odgovornost, tako da ne budite obeshrabreni ako vam se čini da je to sve previše. Svaki korak, koliko god bio mali, je korak u dobrom pravcu.
Koje korake preduzeti da bi uvećali svoju privatnost:
- Budite u vlasništvu sami svojih novčića
- Nikad ne ponavljajte korišćenje istih adresa
- Minimizirajte korišćenje servisa koji zahtevaju identitet (Know your customer - KYC)
- Minimizirajte sve izloženosti trećim licima
- Upravljajte svojim nodom
- Koristite Lightning mrežu za male transakcije
- Nemojte koristiti javne blok pretraživače za svoje transakcije
- Koristite metodu CoinJoin često i rano pri nabavljanju svojih novčića
Budite u vlasništvu sami svojih novčića: Ako ključevi nisu tvoji, onda nije ni bitcoin. Ako neko drugo drži vaš bitcoin za vas, oni znaju sve što se može znati: količinu, istoriju transakcija pa i sve buduće transakcije, itd. Preuzimanje vlasništva bitcoina u svoje ruke je prvi i najvažniji korak.
Nikad ne kroistite istu adresu dvaput: Ponavljanje adresa poništava privatnost pošiljalca i primaoca bitcoina. Ovo se treba izbegavati pod svaku cenu.
Minimizirajte korišćenje servisa koji zahtevaju identitet (KYC): Vezivati svoj legalni identitet za svoje bitcoin adrese je zlo koje se zahteva od strane mnogih državnih nadležnosti. Dok je efektivnost ovih zakona i regulacija disputabilno, posledice njihovog primenjivanja su uglavnom štetne po korisnicima. Ovo je očigledno pošto je česta pojava da se te informacije često izlivaju iz slabo obezbeđenih digitalnih servera. Ako izaberete da koristite KYC servise da bi nabavljali bitcoin, proučite i razumite odnos između vas i tog biznisa. Vi ste poverljivi tom biznisu za sve vaše lične podatke, pa i buduće obezbeđenje tih podataka. Ako i dalje zarađujete kroz fiat novčani sistem, mi preporučujemo da koristite samo bitcoin ekskluzivne servise koji vam dozvoljavaju da autamatski kupujete bitcoin s vremena na vreme. Ako zelite da potpuno da izbegnete KYC, pregledajte https://bitcoinqna.github.io/noKYConly/.
Minimizirajte sve izloženosti trećim licima: Poverljivost trećim licima je bezbednosna rupa (https://nakamotoinstitute.org/trusted-third-parties/). Ako možete biti poverljivi samo sebi, onda bi to tako trebalo da bude.
Upravljajte svojim nodom: Ako nod nije tvoj, onda nisu ni pravila. Upravljanje svojim nodom je suštinska potreba da bi se bitcoin koristio na privatan način. Svaka interakcija sa bitcoin mrežom je posrednjena nodom. Ako vi taj nod ne upravljate, čiji god nod koristite može da vidi sve što vi radite. Ova upustva (https://bitcoiner.guide/node/) su jako korisna da bi započeli proces korišćenja svog noda.
Koristite Lightning mrežu za male transakcije: Pošto Lightning protokol ne koristi glavnu bitcoin mrežu za trasakcije onda je i samim tim povećana privatnost korišćenja bez dodatnog truda. Iako je i dalje rano, oni apsolutno bezobzirni periodi Lightning mreže su verovatno daleko iza nas. Korišćenje Lightning-a za transakcije malih i srednjih veličina će vam pomoći da uvećate privatnost a da smanjite naplate svojih pojedinačnih bitcoin transakcija.
Nemojte koristiti javne blok pretraživače za svoje transakcije: Proveravanje adresa na javnim blok pretraživačima povezuje te adrese sa vašim IP podacima, koji se onda mogu koristiti da se otkrije vaš identitet. Softveri kao Umbrel i myNode vam omogućavaju da lako koristite sami svoj blok pretraživač. Ako morate koristiti javne pretraživače, uradite to uz VPN ili Tor.
Koristite CoinJoin često i rano pri nabavljanju svojih novčića: Pošto je bitcoin večan, primenjivanje saradničkih CoinJoin praksa će vam obezbediti privatnost u budućnosti. Dok su CoinJoin transakcije svakovrsne, softveri koji su laki za korišćenje već sad postoje koji mogu automatizovati ovu vrstu transakcija. Samourai Whirlpool (https://samouraiwallet.com/whirlpool) je odličan izbor za Android korisnike. Joinmarket (https://github.com/joinmarket-webui/jam) se može koristiti na vašem nodu. A servisi postoje koji pri snabdevanju vašeg bitcoina istog trenutka obave CoinJoin tranzakciju automatski.
Zaključak
Svi bi trebalo da se potrude da koriste bitcoin na što privatniji način. Privatnost nije isto što i tajanstvenost. Privatnost je ljudsko pravo i mi svi trebamo da branimo i primenljujemo to pravo. Teško je izbrisati postojeće informacije sa interneta; a izbrisati ih sa bitcoin baze podataka je nemoguće. Iako su daleko od savršenih, alatke postoje danas koje vam omogućavaju da najbolje prakse privatnosti i vi sami primenite. Mi smo vam naglasili neke od njih i - kroz poboljšanje u bitcoin protokolu kroz Taproot i Schnorr - one će postajati sve usavršenije.
Bitcoin postupci se ne mogu lako opisati korišćenjem tradicionalnim konceptima. Pitanja kao što su "Ko je vlasnik ovog novca?" ili "Odakle taj novac potiče?" postaju sve teža da se odgovore a u nekim okolnostima postaju potpuno beznačajna.
Satoši je dizajnirao bitcoin misleći na privatnost. Na nivou protokola svaka bitcoin transakcija je proces "topljenja" koji za sobom samo ostavlja heuristične mrvice hleba. Protokolu nije bitno odakle se pojavio bilo koji bitcoin ili satoši. Niti je njega briga ko je legalan identitet vlasnika. Protokolu je samo važno da li su digitalni potpisi validni. Dokle god je govor slobodan, potpisivanje poruka - privatno ili ne - ne sme biti kriminalan postupak.

2024-05-21 12:38:08Bitcoin transactions explained
A transaction is a piece of data that takes inputs and produces outputs. Forget about the blockchain thing, Bitcoin is actually just a big tree of transactions. The blockchain is just a way to keep transactions ordered.
Imagine you have 10 satoshis. That means you have them in an unspent transaction output (UTXO). You want to spend them, so you create a transaction. The transaction should reference unspent outputs as its inputs. Every transaction has an immutable id, so you use that id plus the index of the output (because transactions can have multiple outputs). Then you specify a script that unlocks that transaction and related signatures, then you specify outputs along with a script that locks these outputs.
As you can see, there's this lock/unlocking thing and there are inputs and outputs. Inputs must be unlocked by fulfilling the conditions specified by the person who created the transaction they're in. And outputs must be locked so anyone wanting to spend those outputs will need to unlock them.
For most of the cases locking and unlocking means specifying a public key whose controller (the person who has the corresponding private key) will be able to spend. Other fancy things are possible too, but we can ignore them for now.
Back to the 10 satoshis you want to spend. Since you've successfully referenced 10 satoshis and unlocked them, now you can specify the outputs (this is all done in a single step). You can specify one output of 10 satoshis, two of 5, one of 3 and one of 7, three of 3 and so on. The sum of outputs can't be more than 10. And if the sum of outputs is less than 10 the difference goes to fees. In the first days of Bitcoin you didn't need any fees, but now you do, otherwise your transaction won't be included in any block.
If you're still interested in transactions maybe you could take a look at this small chapter of that Andreas Antonopoulos book.

2025-05-11 18:24:28Originalni tekst na dvadesetjedan.com.
Autor: Matt Corallo / Prevod na hrvatski: Davor
Bitcoineri, od programera Bitcoin Core-a preko dugogodišnjih entuzijasta Bitcoina do nedavnih pronalazača /r/Bitcoina, vole razgovarati o tome kako je decentralizacija Bitcoina njegova ultimativna značajka. Doduše, rijetko vidite da netko objašnjava zašto je decentralizacija važna. Zasigurno je to zanimljiva značajka iz perspektive računalne znanosti, no zašto bi potrošači, tvrtke ili investitori marili za to? Ova objava je pokušaj da se napiše zašto je decentralizacija temelj vrijednosti Bitcoina i što je još važnije, postavi buduće objave u kojima se govori o tome kada ona to nije.
Kada Bitcoineri govore o decentralizaciji Bitcoina, prva stvar koja se pojavljuje je često spominjani nedostatak inherentnog povjerenja u treću stranu. Dok je dobro postavljeno povjerenje preduvjet za učinkovit rad mnogih sustava, jednom kada se takvo povjerenje izgubi, sustavi mogu postati nevjerojatno krhki. Uzmimo, za primjer, povjerenje u američke banke prije uspostave FDIC-a (Federal Deposit Insurance Corporation). Dok je pristup bankovnim uslugama omogućio više pogodnosti i mnogim tvrtkama učinkovitije poslovanje, poznato je da su banke propadale, pritom upropaštavajući sa sobom sva sredstva klijenata. Dok je predstavljanje FDIC-a i sličnih programa decentraliziralo povjerenje u financijske institucije s jedne strane na dvije, transakcije u velikom dijelu svijeta ne nude takvu zaštitu. Čak i uz takve programe, pojedinci nisu univerzalno zaštićeni od gubitka preko granica i preko određene vrijednosti.
U novije vrijeme, propisi koji dopuštaju pojedinim državnim dužnosnicima jednostrano oduzimanje imovine postali su uobičajeni. Naročito u SAD-u, sada zloglasna “Operacija Choke Point” i programi oduzimanja civilne imovine, omogućili su službenicima za provođenje zakona i privatnim institucijama da zapljenjuju financijsku imovinu i uskraćuju financijske usluge uz malo ili nimalo nadzora. Uklanjanje provjerenih skrbnika i stvaranje sustava s likvidnom imovinom, koja se ne može zaplijeniti, ima potencijal pružiti pouzdanije financijske usluge mnogima koji inače ne bi mogli djelovati učinkovito ili uopće ne bi mogli djelovati. Ova mogućnost da se Bitcoin ne može zaplijeniti, omogućena je samo zbog nedostatka za centraliziranim povjerenjem. Centralizirani sustavi elektroničke gotovine i financijski sustavi su pokušali pružiti takvu pouzdanost, propisi i poslovna stvarnost su to gotovo univerzalno spriječili.
Svojstvo koje je jednako važno za sposobnost Bitcoina da pruža financijske usluge zviždačima, stranim disidentima i porno zvijezdama je njegov otpor cenzuri transakcija. Sposobnost trećih strana da zaplijene imovinu rezultira izravnim i čistim novčanim gubitkom, zamrzavanje imovine može imati sličan učinak. Kada pojedinac ili organizacija više nisu u mogućnosti obavljati transakcije za plaćanje roba i usluga, njihova financijska imovina brzo gubi vrijednost. Iako Bitcoin ima vrlo dobru priču o nemogućnosti zapljene (svaka strana u sustavu nameće nemogućnost bilo koga da potroši Bitcoin bez dodanog privatnog ključa), njegova priča o otporu cenzuri je malo utančanija.
U svijetu u kojem nijedan rudar Bitcoina nema više od 1% ukupne hash snage (ili nešto drugo što je jednako decentralizirano), trebalo bi biti lako pronaći rudara koji je ili anoniman i prihvaća sve transakcije ili je u nadležnosti koja ne pokušava cenzurirati vaše transakcije. Naravno, ovo nije svijet kakav danas imamo, a cenzura transakcija jedan je od većih razloga da se ozbiljno zabrinemo centralizacijom rudarenja (za pune čvorove). Ipak, mogućnost pojedinca da kupi hash snagu (u obliku lako dostupnog starog hardvera ili u obliku njegovog iznajmljivanja) za rudarenje svoje inače cenzurirane transakcije, opcija je sve dok je pravilo najdužeg lanca na snazi kod svih rudara. Iako je znatno skuplji nego što bi bio u istinski decentraliziranom Bitcoinu, to omogućuje Bitcoinu da zadrži neka od svojih anti-cenzuriranih svojstava.
Ako ste već dovoljno dugo u priči oko Bitcoina, možda ćete prepoznati gornja svojstva kao kritična za zamjenjivost. Zamjenjivost, kao ključno svojstvo svakog monetarnog instrumenta, odnosi se na ideju da vrijednost jedne jedinice treba biti ekvivalentna svakoj drugoj jedinici. Bez mogućnosti odmrzavanja/otpora cenzuri i nemogućnosti zapljene, Bitcoin (i svaki drugi monetarni sustav) počinje gubiti zamjenjivost. Trgovci i platni procesori više ne mogu razumno prihvaćati Bitcoin bez provjere niza crnih lista i mnogo truda kako bi bili sigurni da će moći potrošiti Bitcoin koji prihvaćaju. Ako povjerenje u zamjenjivost Bitcoina deformira, njegova bi korist mogla biti značajno deformirana.
Još jedno svojstvo koje proizlazi iz decentralizacije Bitcoina, je njegov otvoreni pristup. Ulagači iz Silicijske doline često ga nazivaju jednim od najzanimljivijih svojstava Bitcoina, a mnogi ga vole nazivati "bez dopuštenja". Sposobnost bilo koga, bilo gdje u svijetu, sa internetskom vezom, da prihvaća Bitcoin za robu i usluge i koristi Bitcoin za kupnju roba i usluga je vrlo uzbudljiva. Opet, ovo svojstvo ovisi o decentralizaciji Bitcoina. Iako postoje mnogi centralizirani pružatelji financijskih usluga, gdje mnogi od njih promoviraju svoju dostupnost bilo kome, sama njihova prisutnost kao centraliziranog tijela koje može proizvoljno uskratiti uslugu, čini ih podložnim budućim promjenama politike iz bilo kojeg razloga. PayPal je, na primjer, utemeljen na idealima univerzalnog pristupa elektroničkoj gotovini. Međutim, zbog svoje pozicije središnje vlasti, brzo je promijenio svoje politike, kako bi udovoljio pritiscima regulatora i politikama postojećeg financijskog sustava na koji se oslanjao. Ovih dana, PayPal je nadaleko poznat po zamrzavanju računa i oduzimanju imovine uz malo ili nimalo upozorenja. U osnovi, oslanjanje na centralizirane strane za usluge nije kompatibilno s univerzalnim otvorenim pristupom u financijskom svijetu.
Primijetit ćete da se sve gore navedene kritične značajke, one koje Bitcoin čine tako uzbudljivim za sve nas, centralizirani sistemi već neko vrijeme mogu implementirati. Zapravo to se radilo i prije, u učinkovitijim sustavima od Bitcoina. Naravno, nikada nisu potrajali, gubeći kritična svojstva nakon podešavanja kako bi se popravila ova ili ona stvar, implementirajući regulatorne sustave cenzure izravno u osnovne slojeve, ograničavajući pristup rastu dobiti i potpuno gašenje. Stvarno, decentralizacija u Bitcoinu sama po sebi nije značajka, već je umjesto toga jedini način za koji znamo da održimo značajke koje želimo u sustavima kojima upravljaju ljudi.

2025-03-20 09:59:20Bald werde es verboten, alleine im Auto zu fahren, konnte man dieser Tage in verschiedenen spanischen Medien lesen. Die nationale Verkehrsbehörde (Dirección General de Tráfico, kurz DGT) werde Alleinfahrern das Leben schwer machen, wurde gemeldet. Konkret erörtere die Generaldirektion geeignete Sanktionen für Personen, die ohne Beifahrer im Privatauto unterwegs seien.
Das Alleinfahren sei zunehmend verpönt und ein Mentalitätswandel notwendig, hieß es. Dieser «Luxus» stehe im Widerspruch zu den Maßnahmen gegen Umweltverschmutzung, die in allen europäischen Ländern gefördert würden. In Frankreich sei es «bereits verboten, in der Hauptstadt allein zu fahren», behauptete Noticiastrabajo Huffpost in einer Zwischenüberschrift. Nur um dann im Text zu konkretisieren, dass die sogenannte «Umweltspur» auf der Pariser Ringautobahn gemeint war, die für Busse, Taxis und Fahrgemeinschaften reserviert ist. Ab Mai werden Verstöße dagegen mit einem Bußgeld geahndet.
Die DGT jedenfalls wolle bei der Umsetzung derartiger Maßnahmen nicht hinterherhinken. Diese Medienberichte, inklusive des angeblich bevorstehenden Verbots, beriefen sich auf Aussagen des Generaldirektors der Behörde, Pere Navarro, beim Mobilitätskongress Global Mobility Call im November letzten Jahres, wo es um «nachhaltige Mobilität» ging. Aus diesem Kontext stammt auch Navarros Warnung: «Die Zukunft des Verkehrs ist geteilt oder es gibt keine».
Die «Faktenchecker» kamen der Generaldirektion prompt zu Hilfe. Die DGT habe derlei Behauptungen zurückgewiesen und klargestellt, dass es keine Pläne gebe, Fahrten mit nur einer Person im Auto zu verbieten oder zu bestrafen. Bei solchen Meldungen handele es sich um Fake News. Teilweise wurde der Vorsitzende der spanischen «Rechtsaußen»-Partei Vox, Santiago Abascal, der Urheberschaft bezichtigt, weil er einen entsprechenden Artikel von La Gaceta kommentiert hatte.
Der Beschwichtigungsversuch der Art «niemand hat die Absicht» ist dabei erfahrungsgemäß eher ein Alarmzeichen als eine Beruhigung. Walter Ulbrichts Leugnung einer geplanten Berliner Mauer vom Juni 1961 ist vielen genauso in Erinnerung wie die Fake News-Warnungen des deutschen Bundesgesundheitsministeriums bezüglich Lockdowns im März 2020 oder diverse Äußerungen zu einer Impfpflicht ab 2020.
Aber Aufregung hin, Dementis her: Die Pressemitteilung der DGT zu dem Mobilitätskongress enthält in Wahrheit viel interessantere Informationen als «nur» einen Appell an den «guten» Bürger wegen der Bemühungen um die Lebensqualität in Großstädten oder einen möglichen obligatorischen Abschied vom Alleinfahren. Allerdings werden diese Details von Medien und sogenannten Faktencheckern geflissentlich übersehen, obwohl sie keineswegs versteckt sind. Die Auskünfte sind sehr aufschlussreich, wenn man genauer hinschaut.
Digitalisierung ist der Schlüssel für Kontrolle
Auf dem Kongress stellte die Verkehrsbehörde ihre Initiativen zur Förderung der «neuen Mobilität» vor, deren Priorität Sicherheit und Effizienz sei. Die vier konkreten Ansätze haben alle mit Digitalisierung, Daten, Überwachung und Kontrolle im großen Stil zu tun und werden unter dem Euphemismus der «öffentlich-privaten Partnerschaft» angepriesen. Auch lassen sie die transhumanistische Idee vom unzulänglichen Menschen erkennen, dessen Fehler durch «intelligente» technologische Infrastruktur kompensiert werden müssten.
Die Chefin des Bereichs «Verkehrsüberwachung» erklärte die Funktion des spanischen National Access Point (NAP), wobei sie betonte, wie wichtig Verkehrs- und Infrastrukturinformationen in Echtzeit seien. Der NAP ist «eine essenzielle Web-Applikation, die unter EU-Mandat erstellt wurde», kann man auf der Website der DGT nachlesen.
Das Mandat meint Regelungen zu einem einheitlichen europäischen Verkehrsraum, mit denen die Union mindestens seit 2010 den Aufbau einer digitalen Architektur mit offenen Schnittstellen betreibt. Damit begründet man auch «umfassende Datenbereitstellungspflichten im Bereich multimodaler Reiseinformationen». Jeder Mitgliedstaat musste einen NAP, also einen nationalen Zugangspunkt einrichten, der Zugang zu statischen und dynamischen Reise- und Verkehrsdaten verschiedener Verkehrsträger ermöglicht.
Diese Entwicklung ist heute schon weit fortgeschritten, auch und besonders in Spanien. Auf besagtem Kongress erläuterte die Leiterin des Bereichs «Telematik» die Plattform «DGT 3.0». Diese werde als Integrator aller Informationen genutzt, die von den verschiedenen öffentlichen und privaten Systemen, die Teil der Mobilität sind, bereitgestellt werden.
Es handele sich um eine Vermittlungsplattform zwischen Akteuren wie Fahrzeugherstellern, Anbietern von Navigationsdiensten oder Kommunen und dem Endnutzer, der die Verkehrswege benutzt. Alle seien auf Basis des Internets der Dinge (IOT) anonym verbunden, «um der vernetzten Gemeinschaft wertvolle Informationen zu liefern oder diese zu nutzen».
So sei DGT 3.0 «ein Zugangspunkt für einzigartige, kostenlose und genaue Echtzeitinformationen über das Geschehen auf den Straßen und in den Städten». Damit lasse sich der Verkehr nachhaltiger und vernetzter gestalten. Beispielsweise würden die Karten des Produktpartners Google dank der DGT-Daten 50 Millionen Mal pro Tag aktualisiert.
Des Weiteren informiert die Verkehrsbehörde über ihr SCADA-Projekt. Die Abkürzung steht für Supervisory Control and Data Acquisition, zu deutsch etwa: Kontrollierte Steuerung und Datenerfassung. Mit SCADA kombiniert man Software und Hardware, um automatisierte Systeme zur Überwachung und Steuerung technischer Prozesse zu schaffen. Das SCADA-Projekt der DGT wird von Indra entwickelt, einem spanischen Beratungskonzern aus den Bereichen Sicherheit & Militär, Energie, Transport, Telekommunikation und Gesundheitsinformation.
Das SCADA-System der Behörde umfasse auch eine Videostreaming- und Videoaufzeichnungsplattform, die das Hochladen in die Cloud in Echtzeit ermöglicht, wie Indra erklärt. Dabei gehe es um Bilder, die von Überwachungskameras an Straßen aufgenommen wurden, sowie um Videos aus DGT-Hubschraubern und Drohnen. Ziel sei es, «die sichere Weitergabe von Videos an Dritte sowie die kontinuierliche Aufzeichnung und Speicherung von Bildern zur möglichen Analyse und späteren Nutzung zu ermöglichen».
Letzteres klingt sehr nach biometrischer Erkennung und Auswertung durch künstliche Intelligenz. Für eine bessere Datenübertragung wird derzeit die Glasfaserverkabelung entlang der Landstraßen und Autobahnen ausgebaut. Mit der Cloud sind die Amazon Web Services (AWS) gemeint, die spanischen Daten gehen somit direkt zu einem US-amerikanischen «Big Data»-Unternehmen.
Das Thema «autonomes Fahren», also Fahren ohne Zutun des Menschen, bildet den Abschluss der Betrachtungen der DGT. Zusammen mit dem Interessenverband der Automobilindustrie ANFAC (Asociación Española de Fabricantes de Automóviles y Camiones) sprach man auf dem Kongress über Strategien und Perspektiven in diesem Bereich. Die Lobbyisten hoffen noch in diesem Jahr 2025 auf einen normativen Rahmen zur erweiterten Unterstützung autonomer Technologien.
Wenn man derartige Informationen im Zusammenhang betrachtet, bekommt man eine Idee davon, warum zunehmend alles elektrisch und digital werden soll. Umwelt- und Mobilitätsprobleme in Städten, wie Luftverschmutzung, Lärmbelästigung, Platzmangel oder Staus, sind eine Sache. Mit dem Argument «emissionslos» wird jedoch eine Referenz zum CO2 und dem «menschengemachten Klimawandel» hergestellt, die Emotionen triggert. Und damit wird so ziemlich alles verkauft.
Letztlich aber gilt: Je elektrischer und digitaler unsere Umgebung wird und je freigiebiger wir mit unseren Daten jeder Art sind, desto besser werden wir kontrollier-, steuer- und sogar abschaltbar. Irgendwann entscheiden KI-basierte Algorithmen, ob, wann, wie, wohin und mit wem wir uns bewegen dürfen. Über einen 15-Minuten-Radius geht dann möglicherweise nichts hinaus. Die Projekte auf diesem Weg sind ernst zu nehmen, real und schon weit fortgeschritten.

2024-03-23 08:57:08Nostr is not decentralized nor censorship-resistant
Peter Todd has been saying this for a long time and all the time I've been thinking he is misunderstanding everything, but I guess a more charitable interpretation is that he is right.
Nostr today is indeed centralized.
Yesterday I published two harmless notes with the exact same content at the same time. In two minutes the notes had a noticeable difference in responses:
The top one was published to
wss://nostr.wine
,wss://nos.lol
,wss://pyramid.fiatjaf.com
. The second was published to the relay where I generally publish all my notes to,wss://pyramid.fiatjaf.com
, and that is announced on my NIP-05 file and on my NIP-65 relay list.A few minutes later I published that screenshot again in two identical notes to the same sets of relays, asking if people understood the implications. The difference in quantity of responses can still be seen today:
These results are skewed now by the fact that the two notes got rebroadcasted to multiple relays after some time, but the fundamental point remains.
What happened was that a huge lot more of people saw the first note compared to the second, and if Nostr was really censorship-resistant that shouldn't have happened at all.
Some people implied in the comments, with an air of obviousness, that publishing the note to "more relays" should have predictably resulted in more replies, which, again, shouldn't be the case if Nostr is really censorship-resistant.
What happens is that most people who engaged with the note are following me, in the sense that they have instructed their clients to fetch my notes on their behalf and present them in the UI, and clients are failing to do that despite me making it clear in multiple ways that my notes are to be found on
wss://pyramid.fiatjaf.com
.If we were talking not about me, but about some public figure that was being censored by the State and got banned (or shadowbanned) by the 3 biggest public relays, the sad reality would be that the person would immediately get his reach reduced to ~10% of what they had before. This is not at all unlike what happened to dozens of personalities that were banned from the corporate social media platforms and then moved to other platforms -- how many of their original followers switched to these other platforms? Probably some small percentage close to 10%. In that sense Nostr today is similar to what we had before.
Peter Todd is right that if the way Nostr works is that you just subscribe to a small set of relays and expect to get everything from them then it tends to get very centralized very fast, and this is the reality today.
Peter Todd is wrong that Nostr is inherently centralized or that it needs a protocol change to become what it has always purported to be. He is in fact wrong today, because what is written above is not valid for all clients of today, and if we drive in the right direction we can successfully make Peter Todd be more and more wrong as time passes, instead of the contrary.

2025-03-15 10:56:08Was nützt die schönste Schuldenbremse, wenn der Russe vor der Tür steht? \ Wir können uns verteidigen lernen oder alle Russisch lernen. \ Jens Spahn
In der Politik ist buchstäblich keine Idee zu riskant, kein Mittel zu schäbig und keine Lüge zu dreist, als dass sie nicht benutzt würden. Aber der Clou ist, dass diese Masche immer noch funktioniert, wenn nicht sogar immer besser. Ist das alles wirklich so schwer zu durchschauen? Mir fehlen langsam die Worte.
Aktuell werden sowohl in der Europäischen Union als auch in Deutschland riesige Milliardenpakete für die Aufrüstung – also für die Rüstungsindustrie – geschnürt. Die EU will 800 Milliarden Euro locker machen, in Deutschland sollen es 500 Milliarden «Sondervermögen» sein. Verteidigung nennen das unsere «Führer», innerhalb der Union und auch an «unserer Ostflanke», der Ukraine.
Das nötige Feindbild konnte inzwischen signifikant erweitert werden. Schuld an allem und zudem gefährlich ist nicht mehr nur Putin, sondern jetzt auch Trump. Europa müsse sich sowohl gegen Russland als auch gegen die USA schützen und rüsten, wird uns eingetrichtert.
Und während durch Diplomatie genau dieser beiden Staaten gerade endlich mal Bewegung in die Bemühungen um einen Frieden oder wenigstens einen Waffenstillstand in der Ukraine kommt, rasselt man im moralisch überlegenen Zeigefinger-Europa so richtig mit dem Säbel.
Begleitet und gestützt wird der ganze Prozess – wie sollte es anders sein – von den «Qualitätsmedien». Dass Russland einen Angriff auf «Europa» plant, weiß nicht nur der deutsche Verteidigungsminister (und mit Abstand beliebteste Politiker) Pistorius, sondern dank ihnen auch jedes Kind. Uns bleiben nur noch wenige Jahre. Zum Glück bereitet sich die Bundeswehr schon sehr konkret auf einen Krieg vor.
Die FAZ und Corona-Gesundheitsminister Spahn markieren einen traurigen Höhepunkt. Hier haben sich «politische und publizistische Verantwortungslosigkeit propagandistisch gegenseitig befruchtet», wie es bei den NachDenkSeiten heißt. Die Aussage Spahns in dem Interview, «der Russe steht vor der Tür», ist das eine. Die Zeitung verschärfte die Sache jedoch, indem sie das Zitat explizit in den Titel übernahm, der in einer ersten Version scheinbar zu harmlos war.
Eine große Mehrheit der deutschen Bevölkerung findet Aufrüstung und mehr Schulden toll, wie ARD und ZDF sehr passend ermittelt haben wollen. Ähnliches gelte für eine noch stärkere militärische Unterstützung der Ukraine. Etwas skeptischer seien die Befragten bezüglich der Entsendung von Bundeswehrsoldaten dorthin, aber immerhin etwa fifty-fifty.
Eigentlich ist jedoch die Meinung der Menschen in «unseren Demokratien» irrelevant. Sowohl in der Europäischen Union als auch in Deutschland sind die «Eliten» offenbar der Ansicht, der Souverän habe in Fragen von Krieg und Frieden sowie von aberwitzigen astronomischen Schulden kein Wörtchen mitzureden. Frau von der Leyen möchte über 150 Milliarden aus dem Gesamtpaket unter Verwendung von Artikel 122 des EU-Vertrags ohne das Europäische Parlament entscheiden – wenn auch nicht völlig kritiklos.
In Deutschland wollen CDU/CSU und SPD zur Aufweichung der «Schuldenbremse» mehrere Änderungen des Grundgesetzes durch das abgewählte Parlament peitschen. Dieser Versuch, mit dem alten Bundestag eine Zweidrittelmehrheit zu erzielen, die im neuen nicht mehr gegeben wäre, ist mindestens verfassungsrechtlich umstritten.
Das Manöver scheint aber zu funktionieren. Heute haben die Grünen zugestimmt, nachdem Kanzlerkandidat Merz läppische 100 Milliarden für «irgendwas mit Klima» zugesichert hatte. Die Abstimmung im Plenum soll am kommenden Dienstag erfolgen – nur eine Woche, bevor sich der neu gewählte Bundestag konstituieren wird.
Interessant sind die Argumente, die BlackRocker Merz für seine Attacke auf Grundgesetz und Demokratie ins Feld führt. Abgesehen von der angeblichen Eile, «unsere Verteidigungsfähigkeit deutlich zu erhöhen» (ausgelöst unter anderem durch «die Münchner Sicherheitskonferenz und die Ereignisse im Weißen Haus»), ließ uns der CDU-Chef wissen, dass Deutschland einfach auf die internationale Bühne zurück müsse. Merz schwadronierte gefährlich mehrdeutig:
«Die ganze Welt schaut in diesen Tagen und Wochen auf Deutschland. Wir haben in der Europäischen Union und auf der Welt eine Aufgabe, die weit über die Grenzen unseres eigenen Landes hinausgeht.»

2025-05-11 18:23:1305.12.2024 / Autor: Katarina Plantak
Vrijednost Bitcoina po prvi put je premašila 100.000 dolara. Ova kriptovaluta svoj masovni rast može na neki način zahvaliti reizboru Donalda Trumpa za američkog predsjednika. On je najavio blaži regulatorni pristup kripto industriji.
Što je Bitcoin?
Bitcoin (BTC) je kriptovaluta (virtualna valuta) dizajnirana da djeluje kao novac i oblik plaćanja izvan kontrole bilo koje osobe, grupe ili entiteta. Time nema potrebe za sudjelovanjem pouzdane treće strane npr. kovnice novca ili banke u financijskim transakcijama. Osoba ili grupa pod pseudonimom Satoshi Nakamoto 31. listopada 2008. objavila je tehnički dokument pod nazivom "Bitcoin: Peer-to-Peer Electronic Cash System". Taj je dokument distribuiran na kriptografsku mailing listu, samo mjesec dana nakon što je investicijska banka Lehman Brothers podnijela zahtjev za najveći bankrot u povijesti SAD-a, a vlada odobrila financijsku pomoć od 700 milijardi dolara.
Nekoliko mjeseci kasnije, 3. siječnja 2009., Bitcoin mreža pokrenula se, uvodeći novi sustav decentralizirane digitalne valute bez središnjeg posrednika.
Tko su osnivači Bitcoina?
Bitcoin je rezultat desetljeća razvoja kriptografije i ideja Cypherpunka iz 1970-ih, s projektima poput B-money, Bit Gold, eCash i HashCash.
Godine 2006., osoba ili grupa pod pseudonimom Satoshi Nakamoto započela je rad na Bitcoinu. Iako su kriptografi poput Hal Finneya, Nicka Szaba, Weija Daija i Adama Backa povezivani sa Satoshijem, svi su to negirali.
Satoshi je surađivao s programerima do 2010., kada je predao kontrolu nad izvornim kodom i 2011. nestao iz javnosti. Danas stotine programera razvijaju Bitcoin, koji ima zajednicu od milijun korisnika.
Kako funkcionira Bitcoin?
Bitcoin se može brzo i sigurno prenijeti na svakoga s Bitcoin adresom poput računa bilo gdje u svijetu, bez potrebe za dopuštenjem ili plaćanjem nepotrebnih naknada. BTC je jedinica valute u Bitcoin sustavu za koju postoji ograničena količina od 21 milijun. Svaki je Bitcoin djeljiv na 100 milijuna "satoshis" ili "sats" – najmanja jedinica Bitcoina, poput centa u dolaru. Bitcoini djeluju kao elektronički novac, omogućujući vam da izvršite plaćanje s univerzalnom valutom bilo gdje. Nalazi se u tzv. novčanicima u digitalnoj verziji. On funkcionira slično kao bankovni račun. Transakcije su moguće zahvaljujući peer-to-peer mreži. Osigurane su sustavom kriptografije javnog i privatnog ključa, objašnjava Kriptomat.
Bitcoin koristi kriptografiju javnog i privatnog ključa za sigurne transakcije. Javna adresa, izvedena iz "hasha" javnog ključa, koristi se za primanje sredstava. Privatni ključ služi kao digitalni potpis odnosno svojevrsna lozinka za autorizaciju transakcija i omogućava pristup sredstvima, pa ga treba čuvati u tajnosti.
Korisnik pokreće transakciju unosom javne adrese primatelja u svoj novčanik. Novčanik koristi privatni ključ za stvaranje digitalnog potpisa, čime se transakcija ovjerava i šalje na Bitcoin mrežu. Transakcija prvo ulazi u "mempool", gdje čeka potvrdu. Svakih desetak minuta, transakcije se grupiraju u blokove, koji se dodaju na blockchain, stvarajući neprekinuti lanac sigurnih zapisa.
Sigurnost sustava je toliko snažna da bi hakiranje jedne adrese trajalo milijardama godina.
Blockchain
Bitcoin je revolucionarno riješio problem dvostruke potrošnje, omogućujući prijenos sredstava izravno između korisnika bez posrednika. Zamislite mrežu stranaca, gdje svaki vodi vlastitu knjigu računa. Kada netko prenese 1 BTC, svi zapisuju transakciju i uspoređuju bilješke. Ako se sve podudaraju, transakcija se potvrđuje. Ako netko pokuša prevariti, njegova bilješka se odbacuje.
Ovaj sustav knjiga računa, distribuiran na globalnoj mreži, čini osnovu Bitcoin blockchaina. Svaki čvor ima identičnu kopiju koja javno i pseudonimno bilježi sve transakcije, osiguravajući točnost i sigurnost bez potrebe za skupim posrednicima.
Zašto je Bitcoin jedinstven i što mu daje vrijednost?
Bitcoin je revolucionirao digitalni novac stvaranjem decentraliziranog, sigurnog i otpornog sustava bez potrebe za posrednicima. Njegov kod omogućuje daljnje inovacije, a povremeno dolazi do "račvanja" koje stvara nove kriptovalute temeljene na Bitcoinu, iako one nikada ne mogu biti isti Bitcoin.
Njegova ključna snaga leži u decentralizaciji – nema središnje figure niti točke neuspjeha. Bitcoin se pokazao kao otporan na izazove, uključujući državne zabrane i snažna račvanja, što dodatno učvršćuje njegovu dugovječnost prema Lindyjevom efektu. Mrežni učinak potiče sve više korisnika da ga prihvate kao sredstvo za pohranu vrijednosti i razmjenu.
Njegova ograničena ponuda od 21 milijun BTC-a stvara oskudicu, čime se suprotstavlja inflacijskim valutama. Bitcoin je zamjenjiv, djeljiv na 100 milijuna dijelova, izdržljiv i prenosiv, što ga čini praktičnijim od zlata. S rastućim prihvaćanjem od strane tvrtki diljem svijeta, njegova vrijednost i korisnost nastavljaju rasti.
Blokovi, rudarenje i nagrade
Prvi Bitcoinblock izrudiran je 3. siječnja 2009. godine. Nazvan je Blok 0. Rudarenje Bitcoina je utrka između rudara za raspršivanje specifičnih vrijednosti i drugih informacija o bloku kako bi se pronašlo rješenje za problem raspršivanja i dodalo blok u blockchain. Pobjednički rudar nagrađen je Bitcoinima. Bitcoin nagrade se prepolovljuju svakih 210.000 blokova. Na primjer, nagrada za blok bila je 50 novih bitcoina u 2009. godini, a 11. svibnja 2020. kad se dogodilo treće prepolovljenje nagrada za svaki blok smanjena je na 6.25 bitcoina. Četvrto prepolovljenje dogodilo se u travnju 2024. i smanjilo je nagradu na 3.125 Bitcoina. Sljedeće prepolovljavanje trebalo bi se dogoditi sredinom 2028. i smanjiti nagradu na 1.5625 BTC.
Do 2140. godine, nakon 32. prepolovljenja, nagrada za rudarenje Bitcoina smanjit će se na nulu, dosegnuvši ukupnu ponudu od 21 milijun BTC-a. Tada će se rudari oslanjati isključivo na naknade za transakcije kako bi pokrili svoje troškove.
Svako prepolovljenje smanjuje količinu novih BTC-a, što povijesno dovodi do porasta cijene zbog smanjene ponude i povećane potražnje. Iako će se učinak budućih prepolovljenja možda smanjivati zbog sve manjih količina nove ponude, do sada su ta prepolovljenja bila ključni pokretači triju glavnih tržišnih ciklusa Bitcoina.

2024-03-19 14:32:01Censorship-resistant relay discovery in Nostr
In Nostr is not decentralized nor censorship-resistant I said Nostr is centralized. Peter Todd thinks it is centralized by design, but I disagree.
Nostr wasn't designed to be centralized. The idea was always that clients would follow people in the relays they decided to publish to, even if it was a single-user relay hosted in an island in the middle of the Pacific ocean.
But the Nostr explanations never had any guidance about how to do this, and the protocol itself never had any enforcement mechanisms for any of this (because it would be impossible).
My original idea was that clients would use some undefined combination of relay hints in reply tags and the (now defunct)
kind:2
relay-recommendation events plus some form of manual action ("it looks like Bob is publishing on relay X, do you want to follow him there?") to accomplish this. With the expectation that we would have a better idea of how to properly implement all this with more experience, Branle, my first working client didn't have any of that implemented, instead it used a stupid static list of relays with read/write toggle -- although it did publish relay hints and kept track of those internally and supportedkind:2
events, these things were not really useful.Gossip was the first client to implement a truly censorship-resistant relay discovery mechanism that used NIP-05 hints (originally proposed by Mike Dilger) relay hints and
kind:3
relay lists, and then with the simple insight of NIP-65 that got much better. After seeing it in more concrete terms, it became simpler to reason about it and the approach got popularized as the "gossip model", then implemented in clients like Coracle and Snort.Today when people mention the "gossip model" (or "outbox model") they simply think about NIP-65 though. Which I think is ok, but too restrictive. I still think there is a place for the NIP-05 hints,
nprofile
andnevent
relay hints and specially relay hints in event tags. All these mechanisms are used together in ZBD Social, for example, but I believe also in the clients listed above.I don't think we should stop here, though. I think there are other ways, perhaps drastically different ways, to approach content propagation and relay discovery. I think manual action by users is underrated and could go a long way if presented in a nice UX (not conceived by people that think users are dumb animals), and who knows what. Reliance on third-parties, hardcoded values, social graph, and specially a mix of multiple approaches, is what Nostr needs to be censorship-resistant and what I hope to see in the future.

31.10.2024 / Autor: Ana Nives Radović
Godišnjica objavljivanja revolucionarnog dokumenta nije samo podsjetnik na nastanak Bitcoina, već i na značajnu promjenu koju je donio u načinu na koji razmišljamo o novcu i ekonomskom suverenitetu. Njegov značaj premašuje ideju o zaradi na promjeni njegove vrijednosti, jer otvara vrata širem razumijevanju digitalne imovine i decentralizovanih finansija koje inspirišu moderno bankarstvo i platne sisteme da se razvijaju u drugačijem smjeru, povećavajući svijest o sigurnosti i dostupnosti.
Šesnaest je godina od objavljivanja dokumenta naslovljenog kao "Bitcoin: A Peer-to-Peer Electronic Cash System", poznatog i kao „biijeli papir“ (white paper) u kojem su izloženi koncept i svrha novog sistema digitalne valute – sistema koji bi funkcionisao nezavisno od bilo koje vlade ili finansijske institucije. Bijeli papir, kojeg je 31. oktobra 2008. objavio pojedinac ili tim ljudi pod imenom Satoši Nakamoto ponudio je smjelo rješenje za sve veći problem – kontrolu valute centralnih banaka i sve veće poteškoće u prenošenju vrijednosti preko interneta bez posrednika. Ovaj trenutak označio je nastanak Bitcoina, revolucionarne digitalne valute i prve kriptovalute na svijetu koja je kasnije lansirana 3. januara 2009. godine.
Bitcoin je nastao u vrijeme finansijske krize 2008. godine, u periodu kada je povjerenje u tradicionalne finansijske sisteme bilo na izuzetno niskom nivou. Ljudi su počeli da se pitaju da li postoji način za upravljanje novcem koji ne zavisi od banaka, koje, kao što su tadašnji događaji pokazali, mogu propasti ili djelovati na načine koji nijesu u najboljem interesu javnosti. Nakamotova inovacija, Bitcoin, bila je zamišljena kao sistem u kojem korisnici mogu direktno slati i primati novac, zaobilazeći potrebu za bankama. U tom procesu, Nakamoto je svijetu predstavio novu tehnologiju kojoj je kasnije američki naučnik i programer Harold Fini dao naziv blockchain – decentralizovan i otporan na manipulacije način za evidentiranje transakcija.
Šta je Bitcoin?
Bitcoin je vrsta digitalne valute koja omogućava ljudima da direktno jedni drugima šalju i primaju vrijednost putem interneta. Za razliku od tradicionalnih valuta, kao što je euro ili dolar, koje kontrolišu vlade i banke, Bitcoin funkcioniše bez centralne vlasti. To znači da nema nikoga ko je zadužen za njega i nema banke koja odlučuje kako se može koristiti. Umjesto toga, Bitcoin se oslanja na veliku mrežu računara širom svijeta koja ga održava i bilježi njegove transakcije. Ova mreža je poznata kao „Bitcoin mreža“.
Kako Bitcoin funkcioniše?
U suštini, Bitcoin funkcioniše kao „decentralizovana digitalna valuta“. Kada kažemo decentralizovana, mislimo da nijedna osoba, kompanija ili vlada ne kontroliše Bitcoin. Umjesto toga, svaka transakcija se bilježi na zajedničkoj knjizi, nazvanoj blockchain, koju održava mreža računara širom svijeta. Svaki put kada neko pošalje ili primi Bitcoin, transakcija se grupiše sa drugima i dodaje u ovaj lanac blokova. Budući da je ovaj lanac kopiran i dijeljen među brojnim računarima, gotovo je neizvodljivo izmijeniti ili hakovati ga, čime se osigurava da Bitcoin transakcije budu bezbjedne i pouzdane.
Još jedan interesantan aspekt je da Bitcoin ima ograničenu ponudu. Kreiran je samo 21 milion bitcoina, što ga čini rijetkom imovinom i sprečava inflaciju na način na koji to može biti slučaj sa tradicionalnim valutama koje se „doštampavaju“. Bitcoin transakcije su omogućene kroz skup kriptografskih pravila, koja ljudima omogućavaju da potvrde svaku transakciju kao legitimnu bez potrebe da vjeruju trećoj strani. Ovaj skup pravila je poznat kao kriptografija, zbog čega se Bitcoin naziva kriptovalutom – prvom koja je ikada stvorena i jedinom koja u potpunosti ima sve karakteristike onoga što je istinska ideja i svrha postojanja kriptovaluta.
Razumijevanje finansijske revolucije Bitcoina
Bitcoin, predstavljen 2008. godine, privukao je globalnu pažnju kao decentralizovana digitalna valuta koja funkcioniše nezavisno od banaka i vlada, ali pored svoje peer-to-peer arhitekture i decentralizovane infrastrukture, on ima jedinstvenu finansijsku karakteristiku – inherentno je deflatoran. Za razliku od fiat valuta poput dolara ili eura, koje centralne banke mogu štampati kada procijene da je to potrebno, ponuda Bitcoina je ograničena, fiksirana i ne povećava se. Ova deflatorna osobina navela je mnoge da ga vide kao revolucionarni finansijski instrument, „digitalno zlato“ koje bi moglo da preoblikuje koncepte vrijednosti, očuvanja bogatstva i monetarne politike.
Fiksna ponuda – limit od 21 miliona
Najkarakterističnija odlika Bitcoina je njegova ograničena ponuda. Kada je Satoši Nakamoto kreirao Bitcoin, postavio je ograničenje na ukupan broj bitcoina koji će ikada postojati – 21 milion. Ovo ograničenje se oštro razlikuje od tradicionalnih fiat valuta, gdje centralne banke mogu povećavati ponudu novca štampanjem dodatne količine. Postavljanjem ovog ograničenja, Nakamoto je osigurao da Bitcoin postane sve rjeđi vremenom, karakteristika koja je dizajnirana za očuvanje vrijednosti kako potražnja raste.
U tradicionalnim finansijama, valute mogu izgubiti vrijednost kada se previše štampaju, što se može vidjeti u slučajevima inflacije. Bitcoinov dizajn, međutim, znači da, kada se posljednji Bitcoin izrudari (što se predviđa oko 2140. godine), novi novčići neće ulaziti u cirkulaciju, što ga efektivno čini prvom deflatornom valutom u velikom obimu.
Mehanizam smanjenje ponude tokom vremena
Oskudica Bitcoina dodatno se pojačava procesom nazvanim „halving“ (prepolovljenje), koji smanjuje stopu stvaranja novih bitcoina. Približno svake četiri godine nagrada koju „rudari“ dobijaju za dodavanje novih blokova u blockchain se prepolovi. Ovaj mehanizam smanjuje mogućnost inflacije Bitcoina tokom vremena, stvarajući predvidivo, postepeno smanjenje ponude.
U početku su rudari dobijali 50 bitcoina po bloku. Nakon prvog halvinga 2012. godine, nagrada je pala na 25, a do 2020. smanjila se na 6,25 bitcoina po bloku. Ovaj proces halvinga će se nastaviti sve do približno 2140. godine, kada će svih 21 milion bitcoina biti u cirkulaciji, a rudari će biti podstaknuti isključivo transakcionim naknadama, umjesto novim novčićima. Halving ima dva osnovna učinka – usporava rast ponude Bitcoina i stvara predvidivu oskudicu koja može podstaći tražnju, jer učesnici na tržištu znaju da će sa svakim ciklusom biti sve manje dostupnih bitcoina.
Zašto je Bitcoin važan?
Većina tradicionalnih valuta je inflaciona po dizajnu. Centralne banke teže kontrolisanoj stopi inflacije, često oko 2%, kako bi podstakle ekonomski rast, ohrabrile potrošnju i pružile fleksibilnost u odgovoru na ekonomske krize. Međutim, ova inflacija može potkopati kupovnu moć fiat valuta vremenom, što je zabrinjavajuće tokom perioda prekomjernog štampanja novca, kao što su mjere i programi kvantitativnog popuštanja viđene posljednjih godina.
Bitcoinov deflatorni dizajn je revolucionaran u ovom kontekstu jer nudi potencijalnu zaštitu od inflacije. Sa fiksnom ponudom, Bitcoin može da dobija na vrijednosti tokom vremena, posebno ako potražnja raste jer postaje rjeđi. Za mnoge, deflatorni model Bitcoina čini ga privlačnim sredstvom za očuvanje bogatstva na način koji tradicionalne valute i imovina ne mogu da ponude.
Pored toga, ovaj model izazvao je promjenu čitave filozofije u načinu na koji ljudi razmišljaju o novcu, investiranju i štednji. Dok tradicionalne finansije podstiču potrošnju i investicije kroz inflaciju, deflatorna priroda Bitcoina može podstaći štednju, jer bi njegova vrijednost mogla da raste u budućnosti. Ovaj kvalitet „čuvara vrijednosti“ naveo je mnoge da Bitcoinu daju naziv „digitalno zlato“.
Ekonomija oskudice – ono što Bitcoinu daje vrijednost
U ekonomiji, oskudica obično povećava vrijednost, jer tražnja za ograničenim resursom može povećati njegovu cijenu. Zlato je, na primjer, dugo bilo čuvar vrijednosti zbog svoje oskudice i poteškoća u vađenju. Bitcoin odražava ovaj koncept u digitalnom svijetu. Inherentno je rijedak zbog ograničenja od 21 milion, i, kao zlato, zahtijeva trud (kroz digitalno rudarenje) da bi ušao u cirkulaciju.
Pored toga, oskudica Bitcoina postaje sve izraženija kako raste interesovanje institucija i pojedinaca. Mnogi investitori privučeni su Bitcoinom kao dugoročnom imovinom upravo zbog ove fiksne ponude, oslanjajući se na to da će rastuća tražnja naspram ograničene ponude povećati njegovu vrijednost tokom vremena. Ova privlačnost je pojačana u regionima sa brzom inflacijom ili ekonomskom nestabilnošću, gdje rizik od devalvacije čini Bitcoin privlačnom alternativom za očuvanje bogatstva.
Bitcoin kao globalni čuvar vrijednosti
Osim što je sredstvo razmjene, deflatorna priroda Bitcoina pozicionira ga kao potencijalni globalni čuvar vrijednosti. Zlato je istorijski imalo ovu ulogu, jer su ga koristili pojedinci, institucije i vlade kao zaštitu od ekonomske nestabilnosti i inflacije. Bitcoin postaje moderni pandan tome, posebno privlačan mlađim generacijama i investitorima sklonim tehnologiji, koji ga vide kao superiornu alternativu.
Deflatorni dizajn takođe omogućava Bitcoinu da prelazi međunarodne granice i nadilazi lokalne ekonomske uslove. U zemljama koje prolaze kroz valutne krize, Bitcoin nudi alternativu koja je bez granica i nezavisna od politika centralne banke. Ova sposobnost da djeluje kao čuvar vrijednosti posebno je značajna na tržištima i ekonomijama u razvoju, gdje je valutna nestabilnost učestalija.
Može li oskudica Bitcoina predstavljati rizik?
Iako deflatorni model Bitcoina ima svoje prednosti, nije bez kritika. Jedna od zabrinutosti je da ekstremna deflacija može obeshrabriti potrošnju. U sistemu gdje vrijednost valute raste tokom vremena, ljudi mogu preferirati štednju umjesto potrošnje ili investiranja, što može dovesti do smanjenja ekonomske aktivnosti. Ekonomisti brinu da bi, ako Bitcoin postane široko prihvaćena valuta, njegova deflatorna priroda mogla ugroziti ekonomski rast podsticanjem „gomilanja“ umesto cirkulacije.
Još jedna kritika se odnosi na fiksnu ponudu Bitcoina u ekonomiji koja stalno raste. Tradicionalne valute su inflatorne kako bi pratile rast populacije, ekonomije i produktivnosti. Sa ograničenom ponudom, Bitcoin ne može da raste u skladu sa ekonomskim razvojem, što bi u teoriji moglo izazvati probleme sa likvidnošću u ekonomiji zasnovanoj na Bitcoinu. Ipak, kako ideja nije da Bitcoin bude jedino sredstvo plaćanja, strah od takvog scenarija je neutemeljen, budući da ekosistem u kojem funkcioniše koegzistira sa nizom drugih platnih sistemna koji su na raspolaganju širom svijeta.
Eliminiše problem dvostrukog trošenja
U svijetu novca postoji veliki problem koji se naziva „dvostruko trošenje“. Zamislite da možete potrošiti iste eure dvaput – platite jedan proizvod ili uslugu, a zatim, nekako, uspijete da ga ponovo potrošite na nešto drugo. U fizičkom svijetu ovo nije problem, ali u računovodstvenom jeste. Ako kao fizičku valutu u gotovini platite nešto, ta količina novca odlazi iz vašeg novčanika, ali u bankovnim transakcijama stvari funkcionišu drugačije.
Da bi se osiguralo da Bitcoin ne može biti kopiran ili potrošen dvaput, koristi se tehnologija zvana blockchain. Nakamotov Bijeli papir još nije pomenuo taj izraz, jer mu je naziv dat nekoliko dana kasnije, no umjesto toga, opisao je koncept „lanca blokova“, postavljajući sistem za evidentiranje transakcija u blokovima koji su međusobno povezani. Ovaj koncept je kasnije postao poznat kao blockchain, termin koji je nastao nakon izdavanja Bitcoina dok su ljudi pokušavali da imenuju osnovnu tehnologiju. Fokus Bijelog papira bio je na tome kako Bitcoin može bezbjedno pratiti i potvrđivati transakcije, koristeći ovaj povezani lanac blokova kao neku vrstu digitalne knjige.
Pristup iz Bijelog papira uveo je revolucionarnu ideju – zajedničku, otpornu na manipulacije evidenciju koja se nije oslanjala na centralnu vlast za ažuriranje ili verifikaciju. Ovaj sistem povezanih blokova (ono što sada nazivamo blockchain) postao je osnova Bitcoina i, kasnije, bezbroj drugih primjena u finansijama, tehnologiji i brojnim drugim oblastima.
Ova baza je poput ogromne digitalne knjige, ili evidencije, u kojoj je svaka Bitcoin transakcija (prenosa novca od jednog do drugog korisnika) zabilježena. Ono što ovu digitalnu evidenciju čini posebnom jeste to što nije smještena na jednom mjestu, niti je pod kontrolom jedne osobe ili institucije – ona je u potpunosti decentralizovana, što znači da se kopije ove knjige čuvaju na hiljadama računara širom svijeta, a svi oni moraju da se saglase oko toga koje transakcije su validne.
Svaki put kada neko pošalje Bitcoin drugoj osobi, ova transakcija se dodaje u blockchain. Da bi se dodala, grupa računara (nazvana „rudari“) mora da verifikuje da je ova transakcija stvarna, što znači da Bitcoin koji se troši već nije korišćen drugdje. Ovi rudari rade zajedno, koristeći složene matematičke operacije, kako bi potvrdili transakcije. Kada se verifikuje, transakcija se dodaje u blockchain, a cijela mreža se ažurira kako bi prepoznala ovu transakciju kao legitimnu. Ovaj proces osigurava da nijedan Bitcoin ne može biti potrošen dvaput, rješavajući problem dvostrukog trošenja.
Peer-to-Peer transakcije bez posrednika
Još jedan veliki razlog zašto je Bitcoin važan je taj što omogućava ljudima da šalju novac direktno jedni drugima bez potrebe za posrednikom. Recimo da želite da pošaljete novac prijatelju koji živi u drugoj zemlji. Obično biste otišli u svoju banku, koja bi se povezala s drugom bankom u toj zemlji, što može trajati danima i uključivati različite naknade.
Međutim, Bitcoin je omogućio da se direktno pošalju sredstva, bez obzira na to gdje se nalazite u svijetu. Pošto je u pitanju peer-to-peer (P2P) način razmjene, nema potrebe za posrednikom da upravlja transakcijom. To može učiniti transakcije bržim i ponekad jeftinijim, posebno kada se sredstva šalju međunarodno. Ova P2P struktura je jedan od glavnih razloga zbog kojih ljudi se na ovaj oblik imovine gleda kao na alternativu složenim transakcijama, posebno važnim za društva i sredine u kojima je dostupnost finansijskih usluga niska.
Transparentnost i sigurnost
U svijetu tradicionalnog bankarstva, ljudi se oslanjaju na banke koje drže novac sigurnim i omogućavaju da transakcije budu poštene i sigurne. Međutim, s Bitcoinom, povjerenje nije smešteno u centralnu banku ili kompaniju, već u samu Bitcoin mrežu, koju održavaju svi računari koji prate blockchain. Pošto je blockchain javan i može ga provjeriti bilo ko, on je veoma transparentan. Svaka transakcija koja je ikada obavljena Bitcoinom zabilježena je u ovoj javnoj knjizi, tako da ako neko pokuša da prevari sistem, to bi bilo očigledno svima.
Transparentnost Bitcoina takođe ga čini veoma sigurnim. Pošto svi u mreži imaju kopiju blockchaina, bilo bi gotovo nemoguće da jedna osoba ili čak grupa ljudi izmijeni ili preuzme kontrolu nad njim. Da biste promijenili blockchain, morali biste kontrolisati više od polovine svih računara širom svijeta u Bitcoin mreži, što je izuzetno teško. Ovaj nivo sigurnosti, u kombinaciji s transparentnošću, pomaže ljudima da se osjećaju sigurno koristeći Bitcoin.
Značaj za razvoj finansija
Tokom godina, Bitcoin je postao više od eksperimenta u digitalnom novcu. Inspirisao je hiljade drugih kreatora latnih rješenja i pokrenuo važne razgovore o budućnosti novca, povjerenja i tehnologije. Kako sve više ljudi počinje da preispituje kako tradicionalne banke funkcionišu i traži nove načine za upravljanje svojim finansijama, Bitcoin ostaje snažna opcija ne samo u smislu alternative, već mogućnosti povezivanja njegove funkcionalnosti sa onim što već postoji u finansijskoj tehnologiji. Njegov značaj je u tome što predstavlja potpuno novi način razmišljanja o novcu i njegovom korišćenju i što rješava neke od ključnih problema koji su karakteristični finansijske sisteme.
Ideja decentralizacije
U mnogim sistemima koje danas koristimo postoji centralna vlast – banka, vlada ili kompanija – koja ima kontrolu i koja donosi pravila, odlučuje ko ima pristup i odobrava aktivnosti, što je prilično spor i skup proces u cjelini. Koncept Bitcoina je drugačiji jer je decentralizovan, a to znači da ne postoji jedna osoba, banka ili organizacija koja donosi odluke, već je to prepušteno mreži koju čine milioni korisničkih uređaja na mreži koji održavaju sistem u funkciji.
Pored toga, decentralizacija onemogućava cenzurisanje, jer niko ne može da interveniše i blokira nečiji pristup ili transakcije. To čini sistem demokratskijim, omogućavajući ljudima širom svijeta da se pridruže bez traženja dozvole.
Kriptografski dokazi – vjerovanje u matematiku, a ne u ljude
Kada nešto kupite koristeći Bitcoin, ne morate se oslanjati na posrednika da verifikuje vašu transakciju. Umjesto toga, Bitcoin koristi nešto što se naziva „kriptografskim dokazom. Kriptografski dokazi su poput digitalnog ključa i brave koji čuvaju informacije sigurnima, jer se oslanjaju na složenu matematiku koja osigurava da se samo validne transakcije dodaju u blockchain, onemogućavajući falsifikovanje ili prevaru.
Kriptografski dokazi funkcionišu tako što kreiraju heš (hash) – dug i jedinstven broj, za svaki blok transakcija. Svaki heš je povezan s prethodnim, što pomaže u obezbjeđivanju cijelog lanca. Matematika iza ovog procesa je toliko složena da bi zahtijevala ogromnu računarsku moć kada bi i pokušala da je razbije. Koristeći kriptografske dokaze, Bitcoin ne zahtijeva povjerenje u ljude, već se umjesto toga, oslanja na neprobojne matematičke algoritme da osigura svaku transakciju.
Proof of Work – digitalna zagonetka koja štiti Bitcoin
Bitcoinova mreža je osigurana procesom koji se naziva Proof of Work (dokaz o radu), koji je najjednostavnije razumjeti ako ga zamislite kao izazovnu zagonetku koju računari, poznati kao „rudari“, moraju da riješe da bi dodali novi blok u blockchain. Prvi računar koji riješi zagonetku dobija priliku da doda blok i dobija nagradu u bitcoinima. Ova zagonetka je izuzetno složena i zahtijeva od rudara da koristi veliku količinu mnogo računarske snage, što je skupo u smislu vremena i energije.
U tom smislu Proof of Work čuva mrežu sigurnom, jer kad bi neko pokušao da prevari sistem ponovnim pisanjem blockchaina, morao ponovo da uradi svako izračunavanja dokaza o radu za svaki blok koji želi da izmijeni, što je praktično nemoguće. Na ovaj način Bitcoin kreira mrežni sistem u kojem je prevara previše skupa i previše složena da bi se bilo kome isplatila.
Šesnaest godina kasnije...
Bitcoin je za ovo vrijeme postao mnogo više od digitalne valute – on je simbol finansijske nezavisnosti i pokretačka snaga nove finansijske tehnologije i ekonomskih koncepata. Pokrenuo je diskusije o budućnosti novca, a inspirisao je brojne pružaoce platnih usluga, uključujući brojne banke širom svijeta i FinTech kompanije, da unapređuju poslovni model.
Zbog količine koja je u opticaju njegova upotreba kao valute ostaje ograničena u poređenju s tradicionalnim novcem, dok njegova cijena nastavlja da fluktuira u zavisnosti od tržišnih okolnosti. U tom smislu uticaj Bitcoina na finansije, tehnologiju i društvo u cjelini već je dubok, navodeći promišljenije i kreativnije istraživanje kako se vrednostima može upravljati i razmenjivati u savremenom svijetu, podstičući značaj decentralizacije i svijest o zaštiti podataka.
Iako često predstavljan kao sredstvo za „brzo bogaćenje“ ili sresdstvo za obavljanje anonimnih transakcija, motivi za njegovo kreiranje, kao i njegova uloga u finansijskom i tehnološkom svijetu potpuno se razlikuju od toga. Bitcoin je prva, najstarija, najvrednija i – u najširem smislu – po svim parametrima jedina prava, potpuno decenztralizovana kriptovaluta koja je transformisala način na koji razmišljamo o novcu, povjerenju i bezbednosti u digitalnoj eri.

2025-03-11 10:22:36«Wir brauchen eine digitale Brandmauer gegen den Faschismus», schreibt der Chaos Computer Club (CCC) auf seiner Website. Unter diesem Motto präsentierte er letzte Woche einen Forderungskatalog, mit dem sich 24 Organisationen an die kommende Bundesregierung wenden. Der Koalitionsvertrag müsse sich daran messen lassen, verlangen sie.
In den drei Kategorien «Bekenntnis gegen Überwachung», «Schutz und Sicherheit für alle» sowie «Demokratie im digitalen Raum» stellen die Unterzeichner, zu denen auch Amnesty International und Das NETTZ gehören, unter anderem die folgenden «Mindestanforderungen»:
- Verbot biometrischer Massenüberwachung des öffentlichen Raums sowie der ungezielten biometrischen Auswertung des Internets.
- Anlasslose und massenhafte Vorratsdatenspeicherung wird abgelehnt.
- Automatisierte Datenanalysen der Informationsbestände der Strafverfolgungsbehörden sowie jede Form von Predictive Policing oder automatisiertes Profiling von Menschen werden abgelehnt.
- Einführung eines Rechts auf Verschlüsselung. Die Bundesregierung soll sich dafür einsetzen, die Chatkontrolle auf europäischer Ebene zu verhindern.
- Anonyme und pseudonyme Nutzung des Internets soll geschützt und ermöglicht werden.
- Bekämpfung «privaten Machtmissbrauchs von Big-Tech-Unternehmen» durch durchsetzungsstarke, unabhängige und grundsätzlich föderale Aufsichtsstrukturen.
- Einführung eines digitalen Gewaltschutzgesetzes, unter Berücksichtigung «gruppenbezogener digitaler Gewalt» und die Förderung von Beratungsangeboten.
- Ein umfassendes Förderprogramm für digitale öffentliche Räume, die dezentral organisiert und quelloffen programmiert sind, soll aufgelegt werden.
Es sei ein Irrglaube, dass zunehmende Überwachung einen Zugewinn an Sicherheit darstelle, ist eines der Argumente der Initiatoren. Sicherheit erfordere auch, dass Menschen anonym und vertraulich kommunizieren können und ihre Privatsphäre geschützt wird.
Gesunde digitale Räume lebten auch von einem demokratischen Diskurs, lesen wir in dem Papier. Es sei Aufgabe des Staates, Grundrechte zu schützen. Dazu gehöre auch, Menschenrechte und demokratische Werte, insbesondere Freiheit, Gleichheit und Solidarität zu fördern sowie den Missbrauch von Maßnahmen, Befugnissen und Infrastrukturen durch «die Feinde der Demokratie» zu verhindern.
Man ist geneigt zu fragen, wo denn die Autoren «den Faschismus» sehen, den es zu bekämpfen gelte. Die meisten der vorgetragenen Forderungen und Argumente finden sicher breite Unterstützung, denn sie beschreiben offenkundig gängige, kritikwürdige Praxis. Die Aushebelung der Privatsphäre, der Redefreiheit und anderer Grundrechte im Namen der Sicherheit wird bereits jetzt massiv durch die aktuellen «demokratischen Institutionen» und ihre «durchsetzungsstarken Aufsichtsstrukturen» betrieben.
Ist «der Faschismus» also die EU und ihre Mitgliedsstaaten? Nein, die «faschistische Gefahr», gegen die man eine digitale Brandmauer will, kommt nach Ansicht des CCC und seiner Partner aus den Vereinigten Staaten. Private Überwachung und Machtkonzentration sind dabei weltweit schon lange Realität, jetzt endlich müssen sie jedoch bekämpft werden. In dem Papier heißt es:
«Die willkürliche und antidemokratische Machtausübung der Tech-Oligarchen um Präsident Trump erfordert einen Paradigmenwechsel in der deutschen Digitalpolitik. (...) Die aktuellen Geschehnisse in den USA zeigen auf, wie Datensammlungen und -analyse genutzt werden können, um einen Staat handstreichartig zu übernehmen, seine Strukturen nachhaltig zu beschädigen, Widerstand zu unterbinden und marginalisierte Gruppen zu verfolgen.»
Wer auf der anderen Seite dieser Brandmauer stehen soll, ist also klar. Es sind die gleichen «Feinde unserer Demokratie», die seit Jahren in diese Ecke gedrängt werden. Es sind die gleichen Andersdenkenden, Regierungskritiker und Friedensforderer, die unter dem großzügigen Dach des Bundesprogramms «Demokratie leben» einem «kontinuierlichen Echt- und Langzeitmonitoring» wegen der Etikettierung «digitaler Hass» unterzogen werden.
Dass die 24 Organisationen praktisch auch die Bekämpfung von Google, Microsoft, Apple, Amazon und anderen fordern, entbehrt nicht der Komik. Diese fallen aber sicher unter das Stichwort «Machtmissbrauch von Big-Tech-Unternehmen». Gleichzeitig verlangen die Lobbyisten implizit zum Beispiel die Förderung des Nostr-Netzwerks, denn hier finden wir dezentral organisierte und quelloffen programmierte digitale Räume par excellence, obendrein zensurresistent. Das wiederum dürfte in der Politik weniger gut ankommen.

2025-05-11 18:22:19Originalan tekst na linkedin.com
12.04.2024 / Autor: Aleksandar Matanović
60/40 portfolio je dugo važio za idealan izbor nekome ko ima umerenu sklonost ka riziku, a nema vremena da prati berzu. Dakle, ubaciš 60% u akcije, 40% u obveznice i pustiš vreme da radi svoje.
Malo sam se igrao sa brojkama i računao šta bi bilo da je neko u taj portfolio ubacio malo Bitkoina. Period koji je obrađen je januar 2014 - januar 2024. Ovde napominjem da nikako nisam radio "cherry picking", to jest nisam birao period u kome se Bitkoin pokazao u najboljem mogućem svetlu. Maltene sam uradio suprotno. Da sam izabrao bilo koji januar pre 2014-te, prinosi na BTC bi bili neuporedivo veći. Čak i da sam izabrao januar 2015-te ili 2016-te, takođe bi prinosi bili veći jer je cena tada bila niža nego u januaru 2014-te. Izbor datuma je bio posledica želje da zaokružim jednu celu deceniju, period nakon kojeg su strpljivi investitori nagrađeni time što ne plaćaju porez na kapitalnu dobit.
Obradio sam 3 realna scenarija:
- Klasičan 60/40 portfolio. Na uloženih $10.000 u januaru 2014. godine, 10 godina kasnije bismo imali tačno $17.434. Prosečan godišnji prinos je 5,72%.
- 99% uloženo u 60/40 portfolio, 1% uloženo u Bitkoin. Na uloženih $10.000, imali bismo $22.505 ili 8,45% godišnje. Samo 1% u BTC, a skoro 3% veći godišnji prinos. (narandžasta linija)
- 90% uloženo u 60/40 portfolio, 10% uloženo u Bitkoin. Sad već postaje zabavno... od $10.000 do $68.145, što bi bilo 21,16% godišnje - jače od proseka Vorena Bafeta. (zelena linija)
Uzeo sam u obzir i rizike i zamislio da je u ovom periodu cena Bitkoina polako padala i na kraju pala na 0. Dakle naredna 2 scenarija su hipotetička.
- 99% uloženo u 60/40 portfolio, 1% uloženo u Bitkoin, Bitkoin propao. Investirano $10.000, dobijeno $17.259 ili 5.61% godišnje. Minimalni gubitak u odnosu na čist 60/40 portfolio iz prvog scenarija. Zbog toga se na grafiku vide 4 linije iako ih ima 5, toliko je mala razlika.
- 90% uloženo u 60/40 portfolio, 10% uloženo u Bitkoin, Bitkoin propao. Investirano $10.000, dobijeno $15.690 ili 4.61% godišnje. To je ona donja. ljubičasta linija na grafikonu. Nije neki prinos, ali nije ni katastrofa.
Mogao sam da idem i sa preko 10%, naravno završili bismo na preko $100.000. Međutim, hteo sam da budem konzervativan i stvari gledam iz ugla investitora koji ipak ima nešto manji apetit ka riziku i nedovljno poznaje Bitkoin. Mogao sam i da uzmem drugačiji period. Na primer, za jan 2012 - jan 2022 bi narandžasta linija završila na preko milion dolara, a zelena na preko 10 miliona. Da, nije greška u računici... zaista biste za 10 godina, počev od januara 2012-te imali preko milion dolara da ste uložili ukupno $10.000, 99% u akcije i obveznice, a 1% u Bitkoin. Sa 90% u akcijama i obveznicama i 10% u Bitkoinu, već ste na 8 cifara.
Istorijske performanse nisu garancija budućih prinosa. Investiranje u Bitkoin je rizično. Ignorisanje Bitkoina je rizično. Svako bira svoj rizik. Ovo nije investicioni savet, ovo je prijateljski savet.

2024-01-29 02:19:25Nostr: a quick introduction, attempt #1
Nostr doesn't have a material existence, it is not a website or an app. Nostr is just a description what kind of messages each computer can send to the others and vice-versa. It's a very simple thing, but the fact that such description exists allows different apps to connect to different servers automatically, without people having to talk behind the scenes or sign contracts or anything like that.
When you use a Nostr client that is what happens, your client will connect to a bunch of servers, called relays, and all these relays will speak the same "language" so your client will be able to publish notes to them all and also download notes from other people.
That's basically what Nostr is: this communication layer between the client you run on your phone or desktop computer and the relay that someone else is running on some server somewhere. There is no central authority dictating who can connect to whom or even anyone who knows for sure where each note is stored.
If you think about it, Nostr is very much like the internet itself: there are millions of websites out there, and basically anyone can run a new one, and there are websites that allow you to store and publish your stuff on them.
The added benefit of Nostr is that this unified "language" that all Nostr clients speak allow them to switch very easily and cleanly between relays. So if one relay decides to ban someone that person can switch to publishing to others relays and their audience will quickly follow them there. Likewise, it becomes much easier for relays to impose any restrictions they want on their users: no relay has to uphold a moral ground of "absolute free speech": each relay can decide to delete notes or ban users for no reason, or even only store notes from a preselected set of people and no one will be entitled to complain about that.
There are some bad things about this design: on Nostr there are no guarantees that relays will have the notes you want to read or that they will store the notes you're sending to them. We can't just assume all relays will have everything — much to the contrary, as Nostr grows more relays will exist and people will tend to publishing to a small set of all the relays, so depending on the decisions each client takes when publishing and when fetching notes, users may see a different set of replies to a note, for example, and be confused.
Another problem with the idea of publishing to multiple servers is that they may be run by all sorts of malicious people that may edit your notes. Since no one wants to see garbage published under their name, Nostr fixes that by requiring notes to have a cryptographic signature. This signature is attached to the note and verified by everybody at all times, which ensures the notes weren't tampered (if any part of the note is changed even by a single character that would cause the signature to become invalid and then the note would be dropped). The fix is perfect, except for the fact that it introduces the requirement that each user must now hold this 63-character code that starts with "nsec1", which they must not reveal to anyone. Although annoying, this requirement brings another benefit: that users can automatically have the same identity in many different contexts and even use their Nostr identity to login to non-Nostr websites easily without having to rely on any third-party.
To conclude: Nostr is like the internet (or the internet of some decades ago): a little chaotic, but very open. It is better than the internet because it is structured and actions can be automated, but, like in the internet itself, nothing is guaranteed to work at all times and users many have to do some manual work from time to time to fix things. Plus, there is the cryptographic key stuff, which is painful, but cool.

2025-03-04 09:40:50Die «Eliten» führen bereits groß angelegte Pilotprojekte für eine Zukunft durch, die sie wollen und wir nicht. Das schreibt der OffGuardian in einem Update zum Thema «EU-Brieftasche für die digitale Identität». Das Portal weist darauf hin, dass die Akteure dabei nicht gerade zimperlich vorgehen und auch keinen Hehl aus ihren Absichten machen. Transition News hat mehrfach darüber berichtet, zuletzt hier und hier.
Mit der EU Digital Identity Wallet (EUDI-Brieftasche) sei eine einzige von der Regierung herausgegebene App geplant, die Ihre medizinischen Daten, Beschäftigungsdaten, Reisedaten, Bildungsdaten, Impfdaten, Steuerdaten, Finanzdaten sowie (potenziell) Kopien Ihrer Unterschrift, Fingerabdrücke, Gesichtsscans, Stimmproben und DNA enthält. So fasst der OffGuardian die eindrucksvolle Liste möglicher Einsatzbereiche zusammen.
Auch Dokumente wie der Personalausweis oder der Führerschein können dort in elektronischer Form gespeichert werden. Bis 2026 sind alle EU-Mitgliedstaaten dazu verpflichtet, Ihren Bürgern funktionierende und frei verfügbare digitale «Brieftaschen» bereitzustellen.
Die Menschen würden diese App nutzen, so das Portal, um Zahlungen vorzunehmen, Kredite zu beantragen, ihre Steuern zu zahlen, ihre Rezepte abzuholen, internationale Grenzen zu überschreiten, Unternehmen zu gründen, Arzttermine zu buchen, sich um Stellen zu bewerben und sogar digitale Verträge online zu unterzeichnen.
All diese Daten würden auf ihrem Mobiltelefon gespeichert und mit den Regierungen von neunzehn Ländern (plus der Ukraine) sowie über 140 anderen öffentlichen und privaten Partnern ausgetauscht. Von der Deutschen Bank über das ukrainische Ministerium für digitalen Fortschritt bis hin zu Samsung Europe. Unternehmen und Behörden würden auf diese Daten im Backend zugreifen, um «automatisierte Hintergrundprüfungen» durchzuführen.
Der Bundesverband der Verbraucherzentralen und Verbraucherverbände (VZBV) habe Bedenken geäußert, dass eine solche App «Risiken für den Schutz der Privatsphäre und der Daten» berge, berichtet das Portal. Die einzige Antwort darauf laute: «Richtig, genau dafür ist sie ja da!»
Das alles sei keine Hypothese, betont der OffGuardian. Es sei vielmehr «Potential». Damit ist ein EU-Projekt gemeint, in dessen Rahmen Dutzende öffentliche und private Einrichtungen zusammenarbeiten, «um eine einheitliche Vision der digitalen Identität für die Bürger der europäischen Länder zu definieren». Dies ist nur eines der groß angelegten Pilotprojekte, mit denen Prototypen und Anwendungsfälle für die EUDI-Wallet getestet werden. Es gibt noch mindestens drei weitere.
Den Ball der digitalen ID-Systeme habe die Covid-«Pandemie» über die «Impfpässe» ins Rollen gebracht. Seitdem habe das Thema an Schwung verloren. Je näher wir aber der vollständigen Einführung der EUid kämen, desto mehr Propaganda der Art «Warum wir eine digitale Brieftasche brauchen» könnten wir in den Mainstream-Medien erwarten, prognostiziert der OffGuardian. Vielleicht müssten wir schon nach dem nächsten großen «Grund», dem nächsten «katastrophalen katalytischen Ereignis» Ausschau halten. Vermutlich gebe es bereits Pläne, warum die Menschen plötzlich eine digitale ID-Brieftasche brauchen würden.
Die Entwicklung geht jedenfalls stetig weiter in genau diese Richtung. Beispielsweise hat Jordanien angekündigt, die digitale biometrische ID bei den nächsten Wahlen zur Verifizierung der Wähler einzuführen. Man wolle «den Papierkrieg beenden und sicherstellen, dass die gesamte Kette bis zu den nächsten Parlamentswahlen digitalisiert wird», heißt es. Absehbar ist, dass dabei einige Wahlberechtigte «auf der Strecke bleiben» werden, wie im Fall von Albanien geschehen.
Derweil würden die Briten gerne ihre Privatsphäre gegen Effizienz eintauschen, behauptet Tony Blair. Der Ex-Premier drängte kürzlich erneut auf digitale Identitäten und Gesichtserkennung. Blair ist Gründer einer Denkfabrik für globalen Wandel, Anhänger globalistischer Technokratie und «moderner Infrastruktur».
Abschließend warnt der OffGuardian vor der Illusion, Trump und Musk würden den US-Bürgern «diesen Schlamassel ersparen». Das Department of Government Efficiency werde sich auf die digitale Identität stürzen. Was könne schließlich «effizienter» sein als eine einzige App, die für alles verwendet wird? Der Unterschied bestehe nur darin, dass die US-Version vielleicht eher privat als öffentlich sei – sofern es da überhaupt noch einen wirklichen Unterschied gebe.

2025-05-11 18:21:0013.06.2023. / Autor: Igor Mirković
Ograničena količina Bitcoina:
Ukupno: 21 milion BTC
Trenutno izrudareno: 19.400.050 BTC
Preostalo za rudarenje: 1.599.950 BTC
Dnevno se izrudari: 900 BTC
Da li je 21 milion Bitcoina dovoljno?
Da li znate koliko je milionera u svetu? Oko 56 miliona milionera, odnosno 1.1% populacije. Ako podelimo 21 milion Bitcoin-a na 56 miliona milionera dobijamo 0.375 BTC po svakom milioneru.
Ograničena zaliha Bitcoina i broj milionera su sami dovoljni da lansiraju cenu, jer bi posedovanje jednog celog Bitcoin-a moglo da postane status moći milionera u budućnosti.
Verovatno bi se oni nekako i dogovorili na ravnopravnu raspodelu da u svetu nema preko 2.000 milijardera, kojima ni 1, a kamoli 0.39 BTC nisu dovoljni za smislenu investiciju.
Zašto kompanije kupuju Bitcoin?
Jedan od faktora koji ovu računicu čini još diskutabilnijom su Bitcoin-i koji su zauvek nestali i zaboravljeni na novčanicima. Nezahvalno je tvrditi koliko je Bitcoin-a „izgubljeno“, ali postoje i istraživanja koja pokazuju da to uopšte nije mali deo celokupne ponude. Kreator Bitcoin-a Satoši odmah je u startu pretpostavio da ovako nešto može da se desi i na ovu okrutnu prirodnu selekciju dao je logičan komentar da će, u slučaju ako neko izgubi pristup svojim Bitcoin-ima, coini koje ima ostatak zajednice samim tim vredeti više.
Kako bismo shvatili zašto je ograničena zaliha izuzetno važna, vratićemo se na staro dobro poređenje zlata i Bitcoin-a. Bitcoin i zlato imaju mnogo sličnosti ali i jednu ključnu razliku. Bitcoin nazivaju digitalnim zlatom, nekada čak i drugom, unapređenom verzijom zlata (Zlato 2.0).
I zlato i Bitcoin:
Imaju fiksnu i ograničenu zalihu. Za BTC se zna koliko ga ima, a za zlato se zna da je ograničeno i da ga nema mnogo. Ne mogu biti lažirani i napravljeni veštački.
Najveća razlika između ova dva čuvara vrednosti je što je zlato u fizičkom obliku, a BTC je isključivo digitalan. Digitalne karakteristike Bitcoin-u daju brojne prednosti u odnosu na zlato: Lako je deljiv na sitnije delove, lako se šalje svuda u svetu, lako se čuva, transportuje i potpuno je transparentan.
Magija od 21 miliona
Ponuda i tražnja… dva jednostavna koncepta, a opet dovoljno sveobuhvatna da definišu i utiču na sve. Kada se spoje, kreiraju apstraktnu pojavu koja se zove vrednost.
Koliko nečega ima i koliko je traženo? Odrednica je za plate radnih mesta, cene imovine, roba, usluga, dobra i gde god želimo da pripišemo neku vrednost možemo početi od tog osnova.
Od samog nastanka čoveka, sve na svetu je imalo percipiranu neograničenu zalihu. Od životinja, zemlje, zlata, vode, nafte. Ljudi su bukvalno konzumirali počevši od pećinskog čoveka pa do danas kao da nema ograničenja ni u čemu.
U stanju smo da konzumiramo i trošimo resurse dok ne nestanu zauvek sa zemlje, samo pogledajte životinje, biljke i sirovine koje su nestale ili su veoma ugrožene zbog uticaja ljudskih „potreba“. Smislili smo čak i šta ćemo kada odrećene sirovine ili životinje nestanu. Napravićemo DNK klonove, sintetičke proizvode, imitaciju koja će nam služiti za naše lične potrebe. Što su zalihe manje i manje, cene su veće ali i želja… potreba za konzumacijom nema cenu.
Šta to znači u slučaju Bitcoin-a? Kao što znamo, Bitcoin je bio prva imovina koja je zaista ograničena, na 21 milion coina, to je sve što će ikada biti stvoreno, a ljudi ne mogu da ga kloniraju, doštampaju, veštački naprave, lažiraju ili slično.
Ograničenost Bitcoin-a se kosi sa svim ljudskim potrošačkim navikama. Uvek postoji način da dobijete više, osim u slučaju Bitcoin-a.
Ova činjenica ograničenosti zaliha je poremetila definiciju ekonomske vrednosti za Bitcoin. To je razlog zašto je on došao do vrednosti od preko 20 hiljada dolara za nešto više od 10 godina. To je jedan od najvećih skokova vrednosti u istoriji čovečanstva i po mišljenju mnogih, samo početak.
Zašto je ograničenje od 21 miliona koje zagovornici ističu toliko važno, koliko je trenutno Bitcoin-a na tržištu i koji je proces koji stvara nove coine odnosno kada će i poslednji BTC biti dostupan?
Bitcoin se često smatra novom vrstom novca koji rešava nedostatke i nudi poboljšanja postojećeg monetarnog sistema. Jedno od tih poboljšanja je fiksna zaliha – 21 milion Bitcoin-a i kodirana logika, koja se ne može menjati, o tome kako će se Bitcoin-i stvarati i po kom principu distribuirati dok se ne postigne ta cifra što se očekuje oko 2150. godine.
Postoje dva elementa fiksne zalihe koji su bitni za razumevanje: Zašto je fiksna zaliha bitna karakteristika za novac i koji sistem Bitcoin koristi kako bi je garantovao.
Odnos ograničene zalihe i vrednosti
Prvi oblici novca pojavili su se nezavisno u različitim kulturama i predstavljali su ključno rešenje i prelazak sa tadašnje trampe. Različite vrste stvari isprobane su kao oblik novca – kokosovi orasi, stoka, ječam, so, biseri, školjke – pre nego što su se zlato i srebro utemeljili kao najefikasniji.
Razlog zbog kojeg su plemeniti metali postali standard za novac bilo je ispunjavanje ključnih karakteristika kako bi novac bio efikasan kao sredstvo razmene:
Prenosiv – Lak za nošenje Izdržljiv – Neće fizički propasti Deljiv – Može se podeliti na manje jednake delove Zamenljiv – Svaka deo je zamenljiv za bilo koju drugu stvar Prepoznatljiv – Očigledno je šta je Oskudan – nema ga u izobilju niti ga je lako nabaviti
Od šest magičnih stvari koje čine novac korisnim za razmenu, poslednja je daleko najvažnija (isto tako je u slučaju novca kao načina očuvanja vrednosti – skladišta vrednosti).
Zamislite sa kakvim problemima bismo se suočavali da je so ostala dominantan oblik novca.
Zlato ispunjava uslov oskudnosti i većinu od ostalih pet, ali je njegova mana izuzetno tešak transport.
Kada je Satoši Nakamoto krenuo sa stvaranjem novog oblika internet novca, on/ona/oni su morali da pronađu način da stvore neku vrstu digitalnog zlata, ali sa isprogramiranom distribucijom odnosno ukupnom ponudom, što je bilo mnogo teže realizovati i napraviti nego što zvuči.
Isprogramirana zaliha
Ako razmislite o najpoznatijim digitalnim formatima- jpeg slikama, Google dokumentima, mp3 datotekama – svi oni mogu da se kopiraju prilično lako. Bitcoin ne može, jer to nije datoteka koja se nalazi na vašem telefonu ili laptopu, već postoji u obliku zapisa koji je povezan sa adresom – mestom na bitcoin blokčejnu– koji možete zamisliti kao broj bankovnog računa.
Ako imate pristup bitcoin adresi i neka sredstva u Bitcoin-u na njoj, možete ga iskoristiti. Dakle, Bitcoin blokčejn kao monetarni sistem je kuća svih bitkoina koji su u opticaju, drugim rečima, ukupne ponude Bitkoina.
Sledeće logično pitanje je kako se kontroliše i održava bitkoin mreža? Česta zabluda koja postoji zbog tradicionalnih finansijskih sistema je da ko god to kontroliše može stvoriti onoliko BTC-a koliko želi? Možda, ako bi to kontrolisala jedna osoba, sigurno bi bila u iskušenju… tako u stvari funkcioniše postojeći novac centralnih banaka.
Kako nastaju Bitkoini?
Jedan od najmagičnijih mehanizama Bitcoin sistema je način na koji se stvaraju novi Bitcoin-i kroz proces koji se zove rudarenje. To je prilično složen proces, tako da ko želi da istraži i kopa dublje može se informiše na našem blogu u sekciji rudarenje.
Bitcoin sistem funkcioniše u skladu sa skupom pravila koji se nazivaju Bitcoin Protokol. Taj skup pravila kaže da će ukupno postojati maksimalno 21 milion, sa fiksnim brojem Bitcoin-a koji se kreira svakih 10 minuta kao nagrada za rudare koji obrađuju nove transakcije u bloku podataka. Blokovi podataka su povezani zajedno sa neraskidivim kriptografskim vezama – otuda i termin blokčejn.
Rudarenje kriptovaluta – Kakva su iskustva srpskih rudara?
Prvi blok je iskopan u januaru 2009. godine, kada je nagrada za rudare bila 50 BTC-a. Tako je 50 novih koina puštano u promet svakih 10 minuta.
Protokol o Bitcoin-u je programiran da kada se stvori 210.000 blokova, nagrada se prepolovi, što se dešava otprilike svake četiri godine i naziva se Bitcoin halving.
Bitcoin je do sada prošao kroz tri halvinga. Umesto da bude inflatoran – sa stalno rastućom ponudom – koja narušava vrednost, Bitcoin je deflatoran jer raste uz opadajuću maržu, koja će na kraju dostići nulu kada se dostigne količina od distribuiranih 21 milion BTC-a.
Zašto baš 21 milion?
Neka jednostavna matematika ukazuje na to da je Satoši možda imao mnogo veću viziju o bitkoinu – što bolje objašnjava zašto je izabran maksimalni iznos od 21 milion.
U vreme stvaranja Bitcoin-a, celokupna svetska ponuda novca iznosila je približno 21 hiljadu milijardi dolara. Ova cifra, poznata kao M1 novčana masa, sastoji se od ukupne vrednosti celokupnog fizičkog novca na svetu, uključujući gotovinu, kovanice, čekove i još mnogo toga.
Ako bi Bitcoin narastao i postao jedinstvena svetska valuta — zamenjujući sve one od kojih se sastoji M1 cifra — onda bi svaki BTC vredeo milion dolara. Pošto u svakom Bitcoin-u ima 100 miliona satošija, to bi postavilo vrednost svakog satošija na 0,01 dolara.
Činjenica da su ovi brojevi tako blisko usklađeni bila bi izuzetna slučajnost, ako nije namerno.
Druga verzija
Iako je teorija zamene novčane mase M1 možda najverovatnije obrazloženje zašto je Satoši odabrao 21 milion da bude limit za Bitcoin, postoji još jedno donekle jednostavnije objašnjenje.
Gledajući parametre koji se koriste za kontrolu distribucije Bitcoin-a, postaje jasno da cifra od 21 milion BTC-a omogućava mreži da osigura da se blokovi rudare u redovnom vremenskom okviru (10 minuta).
Takođe. osigurava da se količina bitkoina koji se isplaćuje rudarima kao nagrade za blok vremenom smanjuje, kako se maksimalna ponuda približava granici. Kako se ispostavilo, parametri koje je Satoshi postavio za ovo neizbežno dovode do proizvodnje od maksimalno 21 miliona BTC. Na osnovu ove karakteristike, ukupno 210.000 blokova treba da se rudari u svakom četvorogodišnjem ciklusu, nakon čega se nagrada za blok prepolovi.
U prvom ciklusu je puštano 50 BTC po bloku; ovo je prepolovljeno na 25 BTC po bloku u 2012. godini, zatim ponovo na 12,5 BTC po bloku u 2016. Nakon prepolovljenja u 2020., trenutno je na 6,25 BTC po bloku.
Ako nastavimo videćemo da je zbir nagrada za blok za svaki ciklus jednak 100 (50 + 25 + 6,25 +3,125, itd.). Množenjem ovog broja sa cifrom od 210.000 blokova, dobijate maksimalnu moguću ponudu od 21 milion.
Dakle, da li je zaliha Bitcoin-a filozofski gest ili proizvod nemilosrdne matematičke logike? Samo Satoši Nakamoto zaista zna.

2024-01-15 11:15:06Pequenos problemas que o Estado cria para a sociedade e que não são sempre lembrados
- **vale-transporte**: transferir o custo com o transporte do funcionário para um terceiro o estimula a morar longe de onde trabalha, já que morar perto é normalmente mais caro e a economia com transporte é inexistente. - **atestado médico**: o direito a faltar o trabalho com atestado médico cria a exigência desse atestado para todas as situações, substituindo o livre acordo entre patrão e empregado e sobrecarregando os médicos e postos de saúde com visitas desnecessárias de assalariados resfriados. - **prisões**: com dinheiro mal-administrado, burocracia e péssima alocação de recursos -- problemas que empresas privadas em competição (ou mesmo sem qualquer competição) saberiam resolver muito melhor -- o Estado fica sem presídios, com os poucos existentes entupidos, muito acima de sua alocação máxima, e com isto, segundo a bizarra corrente de responsabilidades que culpa o juiz que condenou o criminoso por sua morte na cadeia, juízes deixam de condenar à prisão os bandidos, soltando-os na rua. - **justiça**: entrar com processos é grátis e isto faz proliferar a atividade dos advogados que se dedicam a criar problemas judiciais onde não seria necessário e a entupir os tribunais, impedindo-os de fazer o que mais deveriam fazer. - **justiça**: como a justiça só obedece às leis e ignora acordos pessoais, escritos ou não, as pessoas não fazem acordos, recorrem sempre à justiça estatal, e entopem-na de assuntos que seriam muito melhor resolvidos entre vizinhos. - **leis civis**: as leis criadas pelos parlamentares ignoram os costumes da sociedade e são um incentivo a que as pessoas não respeitem nem criem normas sociais -- que seriam maneiras mais rápidas, baratas e satisfatórias de resolver problemas. - **leis de trãnsito**: quanto mais leis de trânsito, mais serviço de fiscalização são delegados aos policiais, que deixam de combater crimes por isto (afinal de contas, eles não querem de fato arriscar suas vidas combatendo o crime, a fiscalização é uma excelente desculpa para se esquivarem a esta responsabilidade). - **financiamento educacional**: é uma espécie de subsídio às faculdades privadas que faz com que se criem cursos e mais cursos que são cada vez menos recheados de algum conhecimento ou técnica útil e cada vez mais inúteis. - **leis de tombamento**: são um incentivo a que o dono de qualquer área ou construção "histórica" destrua todo e qualquer vestígio de história que houver nele antes que as autoridades descubram, o que poderia não acontecer se ele pudesse, por exemplo, usar, mostrar e se beneficiar da história daquele local sem correr o risco de perder, de fato, a sua propriedade. - **zoneamento urbano**: torna as cidades mais espalhadas, criando uma necessidade gigantesca de carros, ônibus e outros meios de transporte para as pessoas se locomoverem das zonas de moradia para as zonas de trabalho. - **zoneamento urbano**: faz com que as pessoas percam horas no trânsito todos os dias, o que é, além de um desperdício, um atentado contra a sua saúde, que estaria muito melhor servida numa caminhada diária entre a casa e o trabalho. - **zoneamento urbano**: torna ruas e as casas menos seguras criando zonas enormes, tanto de residências quanto de indústrias, onde não há movimento de gente alguma. - **escola obrigatória + currículo escolar nacional**: emburrece todas as crianças. - **leis contra trabalho infantil**: tira das crianças a oportunidade de aprender ofícios úteis e levar um dinheiro para ajudar a família. - **licitações**: como não existem os critérios do mercado para decidir qual é o melhor prestador de serviço, criam-se comissões de pessoas que vão decidir coisas. isto incentiva os prestadores de serviço que estão concorrendo na licitação a tentar comprar os membros dessas comissões. isto, fora a corrupção, gera problemas reais: __(i)__ a escolha dos serviços acaba sendo a pior possível, já que a empresa prestadora que vence está claramente mais dedicada a comprar comissões do que a fazer um bom trabalho (este problema afeta tantas áreas, desde a construção de estradas até a qualidade da merenda escolar, que é impossível listar aqui); __(ii)__ o processo corruptor acaba, no longo prazo, eliminando as empresas que prestavam e deixando para competir apenas as corruptas, e a qualidade tende a piorar progressivamente. - **cartéis**: o Estado em geral cria e depois fica refém de vários grupos de interesse. o caso dos taxistas contra o Uber é o que está na moda hoje (e o que mostra como os Estados se comportam da mesma forma no mundo todo). - **multas**: quando algum indivíduo ou empresa comete uma fraude financeira, ou causa algum dano material involuntário, as vítimas do caso são as pessoas que sofreram o dano ou perderam dinheiro, mas o Estado tem sempre leis que prevêem multas para os responsáveis. A justiça estatal é sempre muito rígida e rápida na aplicação dessas multas, mas relapsa e vaga no que diz respeito à indenização das vítimas. O que em geral acontece é que o Estado aplica uma enorme multa ao responsável pelo mal, retirando deste os recursos que dispunha para indenizar as vítimas, e se retira do caso, deixando estas desamparadas. - **desapropriação**: o Estado pode pegar qualquer propriedade de qualquer pessoa mediante uma indenização que é necessariamente inferior ao valor da propriedade para o seu presente dono (caso contrário ele a teria vendido voluntariamente). - **seguro-desemprego**: se há, por exemplo, um prazo mínimo de 1 ano para o sujeito ter direito a receber seguro-desemprego, isto o incentiva a planejar ficar apenas 1 ano em cada emprego (ano este que será sucedido por um período de desemprego remunerado), matando todas as possibilidades de aprendizado ou aquisição de experiência naquela empresa específica ou ascensão hierárquica. - **previdência**: a previdência social tem todos os defeitos de cálculo do mundo, e não importa muito ela ser uma forma horrível de poupar dinheiro, porque ela tem garantias bizarras de longevidade fornecidas pelo Estado, além de ser compulsória. Isso serve para criar no imaginário geral a idéia da __aposentadoria__, uma época mágica em que todos os dias serão finais de semana. A idéia da aposentadoria influencia o sujeito a não se preocupar em ter um emprego que faça sentido, mas sim em ter um trabalho qualquer, que o permita se aposentar. - **regulamentação impossível**: milhares de coisas são proibidas, há regulamentações sobre os aspectos mais mínimos de cada empreendimento ou construção ou espaço. se todas essas regulamentações fossem exigidas não haveria condições de produção e todos morreriam. portanto, elas não são exigidas. porém, o Estado, ou um agente individual imbuído do poder estatal pode, se desejar, exigi-las todas de um cidadão inimigo seu. qualquer pessoa pode viver a vida inteira sem cumprir nem 10% das regulamentações estatais, mas viverá também todo esse tempo com medo de se tornar um alvo de sua exigência, num estado de terror psicológico. - **perversão de critérios**: para muitas coisas sobre as quais a sociedade normalmente chegaria a um valor ou comportamento "razoável" espontaneamente, o Estado dita regras. estas regras muitas vezes não são obrigatórias, são mais "sugestões" ou limites, como o salário mínimo, ou as 44 horas semanais de trabalho. a sociedade, porém, passa a usar esses valores como se fossem o normal. são raras, por exemplo, as ofertas de emprego que fogem à regra das 44h semanais. - **inflação**: subir os preços é difícil e constrangedor para as empresas, pedir aumento de salário é difícil e constrangedor para o funcionário. a inflação força as pessoas a fazer isso, mas o aumento não é automático, como alguns economistas podem pensar (enquanto alguns outros ficam muito satisfeitos de que esse processo seja demorado e difícil). - **inflação**: a inflação destrói a capacidade das pessoas de julgar preços entre concorrentes usando a própria memória. - **inflação**: a inflação destrói os cálculos de lucro/prejuízo das empresas e prejudica enormemente as decisões empresariais que seriam baseadas neles. - **inflação**: a inflação redistribui a riqueza dos mais pobres e mais afastados do sistema financeiro para os mais ricos, os bancos e as megaempresas. - **inflação**: a inflação estimula o endividamento e o consumismo. - **lixo:** ao prover coleta e armazenamento de lixo "grátis para todos" o Estado incentiva a criação de lixo. se tivessem que pagar para que recolhessem o seu lixo, as pessoas (e conseqüentemente as empresas) se empenhariam mais em produzir coisas usando menos plástico, menos embalagens, menos sacolas. - **leis contra crimes financeiros:** ao criar legislação para dificultar acesso ao sistema financeiro por parte de criminosos a dificuldade e os custos para acesso a esse mesmo sistema pelas pessoas de bem cresce absurdamente, levando a um percentual enorme de gente incapaz de usá-lo, para detrimento de todos -- e no final das contas os grandes criminosos ainda conseguem burlar tudo.

2025-03-01 10:39:35Ständige Lügen und Unterstellungen, permanent falsche Fürsorge \ können Bausteine von emotionaler Manipulation sein. Mit dem Zweck, \ Macht und Kontrolle über eine andere Person auszuüben. \ Apotheken Umschau
Irgendetwas muss passiert sein: «Gaslighting» ist gerade Thema in vielen Medien. Heute bin ich nach längerer Zeit mal wieder über dieses Stichwort gestolpert. Das war in einem Artikel von Norbert Häring über Manipulationen des Deutschen Wetterdienstes (DWD). In diesem Fall ging es um eine Pressemitteilung vom Donnerstag zum «viel zu warmen» Winter 2024/25.
Häring wirft der Behörde vor, dreist zu lügen und Dinge auszulassen, um die Klimaangst wach zu halten. Was der Leser beim DWD nicht erfahre, sei, dass dieser Winter kälter als die drei vorangegangenen und kälter als der Durchschnitt der letzten zehn Jahre gewesen sei. Stattdessen werde der falsche Eindruck vermittelt, es würde ungebremst immer wärmer.
Wem also der zu Ende gehende Winter eher kalt vorgekommen sein sollte, mit dessen Empfinden stimme wohl etwas nicht. Das jedenfalls wolle der DWD uns einreden, so der Wirtschaftsjournalist. Und damit sind wir beim Thema Gaslighting.
Als Gaslighting wird eine Form psychischer Manipulation bezeichnet, mit der die Opfer desorientiert und zutiefst verunsichert werden, indem ihre eigene Wahrnehmung als falsch bezeichnet wird. Der Prozess führt zu Angst und Realitätsverzerrung sowie zur Zerstörung des Selbstbewusstseins. Die Bezeichnung kommt von dem britischen Theaterstück «Gas Light» aus dem Jahr 1938, in dem ein Mann mit grausamen Psychotricks seine Frau in den Wahnsinn treibt.
Damit Gaslighting funktioniert, muss das Opfer dem Täter vertrauen. Oft wird solcher Psychoterror daher im privaten oder familiären Umfeld beschrieben, ebenso wie am Arbeitsplatz. Jedoch eignen sich die Prinzipien auch perfekt zur Manipulation der Massen. Vermeintliche Autoritäten wie Ärzte und Wissenschaftler, oder «der fürsorgliche Staat» und Institutionen wie die UNO oder die WHO wollen uns doch nichts Böses. Auch Staatsmedien, Faktenchecker und diverse NGOs wurden zu «vertrauenswürdigen Quellen» erklärt. Das hat seine Wirkung.
Warum das Thema Gaslighting derzeit scheinbar so populär ist, vermag ich nicht zu sagen. Es sind aber gerade in den letzten Tagen und Wochen auffällig viele Artikel dazu erschienen, und zwar nicht nur von Psychologen. Die Frankfurter Rundschau hat gleich mehrere publiziert, und Anwälte interessieren sich dafür offenbar genauso wie Apotheker.
Die Apotheken Umschau machte sogar auf «Medical Gaslighting» aufmerksam. Davon spreche man, wenn Mediziner Symptome nicht ernst nähmen oder wenn ein gesundheitliches Problem vom behandelnden Arzt «schnöde heruntergespielt» oder abgetan würde. Kommt Ihnen das auch irgendwie bekannt vor? Der Begriff sei allerdings irreführend, da er eine manipulierende Absicht unterstellt, die «nicht gewährleistet» sei.
Apropos Gaslighting: Die noch amtierende deutsche Bundesregierung meldete heute, es gelte, «weiter [sic!] gemeinsam daran zu arbeiten, einen gerechten und dauerhaften Frieden für die Ukraine zu erreichen». Die Ukraine, wo sich am Montag «der völkerrechtswidrige Angriffskrieg zum dritten Mal jährte», verteidige ihr Land und «unsere gemeinsamen Werte».
Merken Sie etwas? Das Demokratieverständnis mag ja tatsächlich inzwischen in beiden Ländern ähnlich traurig sein. Bezüglich Friedensbemühungen ist meine Wahrnehmung jedoch eine andere. Das muss an meinem Gedächtnis liegen.

Bitcoin halving je ključni događaj Bitcoin mreže koji umanjuje nagrade za rudarenje, utiče na trend tržišta, profitabilnost rudara i pokreće inovacije u kripto ekosistemu.
Smanjenje nagrade za rudare utiče i na cenu Bitcoin-a, a veliki investitori i rudarska postrojenja igraju značajnu ulogu u oblikovanju tržišnog odgovora na ovaj događaj.
Predstojeći halving može podstaći investitore i rudare da pored Bitcoin-a istraže ponudu altkoina ali i da potraže isplativija rešenja za rudarenje.
Sta je Bitcoin halving?
Bitcoin halving je proces smanjenja nagrade koju rudari dobijaju za potvrđivanje transakcija na Bitcoin mreži. Ovaj proces se dešava svakih 210.000 blokova, što pada na svake četiri godine.
Kada je Bitcoin prvi put pokrenut 2009. godine, nagrada za izrudaren blok u kome se čuvaju transakcije bila je 50 BTC. Nakon prvog halvinga 2012. godine, nagrada se smanjila na 25 BTC po bloku. Drugi halving se dogodio 2016. godine i nagrada se smanjila na 12,5 BTC po bloku. Treći halving se dogodio u maju 2020. godine i nagrada se smanjila na 6,25 BTC po bloku.
Sledeći halving se očekuje 2024. godine i nagrada će se ponovo smanjiti upola, na 3,125 BTC po bloku.
Smanjenje nagrade za cilj ima smanjenje količine novih Bitcoina koji se stvaraju kako bi se dostigla ograničena ukupna ponuda od 21 milion BTC. Ova dinamika stvaranja novih coina takođe utiče na cenu Bitcoina.
Kada se poslednji Bitcoin izrudari, nagrade po izrudarenom bloku će nestati. To se očekuje oko 2140. godine. Nakon toga, rudari će moći da zarađuju samo kroz naknade za realizaciju transakcija koje korisnici mreže plaćaju.
Bitcoin halving je događaj koji smanjuje broj novih Bitcoina koji se generišu po bloku.
U skladu sa opštim zakonom ekonomije – manja ponuda uz stabilnu tražnju bi trebalo da rezultira višim cenama.
Godinu dana pre dugo očekivanog halvinga, stručnjaci i investitori u kripto industriji pažljivo prate njegov potencijalni uticaj na tržište.
Bitcoin halving je je osnovni deflatorni mehanizam definisan u Bitcoin protokolu. Dizajniran je da smanji nagradu za rudarenje za 50% na svakih 210.000 blokova ili otprilike svake četiri godine. Ovo smanjenje ima dvostruku svrhu.
Jedna je kontrola stope inflacije Bitcoin-a kroz imitaciju oskudice, a druga je garancija predvidljive i sve manje ponude novog BTC-a koji ulazi na tržište.
Ovaj mehanizam ima za cilj da očuva vrednost BTC-a tokom vremena, čineći ga atraktivnim čuvarom vrednosti. Kao rezultat toga, halving je ključna komponenta dugoročne ekonomske održivosti Bitcoin-a.
Istorijski gledano, halving je značajno uticao na cenu Bitcoina zbog smanjene ponude novog BTC-a na tržištu. Na primer, u halving događajima 2012, 2016. i 2020. cena bitcoina je doživela značajan porast u mesecima nakon prepolovljavanja nagrade, zato što su trgovci očekivali šok na strani ponude i povećanu potražnju za oskudnijom imovinom.
Trenutno, nagrada za rudarenje iznosi 6,25 BTC po bloku. Nakon sledećeg halvinga koji se očekuje 2024. godine, nagrada za rudarenje će se smanjiti na 3,125 BTC po bloku.
Kakve je posledice halving uzrokovao u prošlosti?
Stručnjaci predviđaju da bi halving mogao dovesti do značajnih promena u ceni BTC-a, kao što je bio slučaj prethodnog puta. Međutim, faktori kao što su globalni ekonomski uslovi, regulatorni razvoj i strategije institucionalnih investitora mogu uticati na ishod.
Tokom halvinga 2012. cena Bitcoina je porasla sa oko 11 dolara u novembru 2012. na oko 1.100 dolara u novembru 2013. godine, što je značajno povećanje u roku od godinu dana.
Tokom ovog perioda, Bitcoin je još uvek bio relativno nov koncept. A tržište su prvenstveno pokretali mali investitori i rani korisnici koji su predvideli potencijal decentralizovane digitalne valute.
Halving u 2016. doveo je do povećanja cene bitcoina sa oko 650 dolara u julu 2016. na skoro 20.000 dolara u decembru 2017. Taj rast je bilo podstaknut povećanom pažnjom velikih medija i ulaskom institucionalnih investitora.
Ipak, regulatorni razvoji i pokušaji da se nametnu strožija pravila za kripto berze, doprineli su nestabilnosti tržišta.
Halving iz 2020. doveo je do povećanja cene bitcoina sa oko 9.000 dolara u maju 2020. na istorijski maksimum od oko 69.000 dolara u novembru 2021. Halving 2020. okarakterisan je rekordnim institucionalnim interesovanjem, vođenim velikim korporacijama i investicionim fondovima koji su ušli na kripto tržište.
COVID-19 pandemija takođe je odigrala značajnu ulogu u oblikovanju raspoloženja na tržištu. Kako su globalna ekonomska kriza i neviđene fiskalne stimulativne mere izazvale zabrinutost zbog inflacije i slabljenja nacionalnih valuta, potražnja za Bitcoinom je rasla.
Kada je sledeći datum Bitkoin halvinga?
Sledeći datum Bitkoin halvinga je zakazan za blok 840.000 – predviđeno je da će se desiti 20. aprila 2024. u 09:20 UTC.
Na datum Bitkoin halvinga predviđeno je da nagrada za blok padne sa 6,25 bitkoina po bloku na 3,125 bitkoina po bloku.
BTC Halving 2024
Analizirajući istorijske obrasce Bitcoin halvinga, čini se da investitori često akumuliraju Bitcoin uoči halvinga i to upravo nekih godinu dana pre.
To bi značilo, ako pretpostavimo da je najniža cena za ovaj ciklus bila u novembru prošle godine (kada je Bitcoin dostigao minimum od oko 16.000 dolara), trenutno se pripremamo za novi vrh koji bi se desio godinu dana nakon halvinga odnosno dve godine od sada. Ova teorija zasniva se na verovanju da kretanja cena prate sličan obrazac kao prethodnih događaja.
Međutim, važno je znati da ne znači nužno da će doći do povećanja ili stagnacije cene Bitcoina. Kripto tržište je značajno sazrelo od poslednjeg halvinga 2020. godine i sada postoji daleko više kriptovaluta koje su u prvom planu korisnika.
Porast rudarske snage
Predstojeći halving će smanjiti nagrade za rudarenje za 50%, što vrši značajan finansijski pritisak na Bitcoin rudare. Ovo smanjenje nagrada tera rudare da prilagode svoje poslovanje kako bi održali profitabilnost i nastavili da održavaju blokčejn mrežu.
Kao odgovor na smanjene nagrade, rudari mogu izabrati da nadograde svoju opremu, kroz ulaganje u energetski efikasniji i moćniji hardver kako bi optimizovali svoje rudarske operacije. Koristeći najnoviju tehnologiju, rudari mogu smanjiti potrošnju energije ali i operativne troškove.
Međutim, povećani troškovi povezani sa nadogradnjom opreme i poboljšanjem energetske efikasnosti mogu nepogodno uticati na manje rudare. Ovim manjim rudarskim postrojenjima često nedostaju finansijska sredstva da se takmiče sa većim, dobro finansiranim rudarskim fondovima.
Kao rezultat toga, neki manji rudari mogu biti primorani da napuste tržište ili mogu biti primorani da se pripoje većim rudarskim postrojenjima kako bi opstali u trci za nagrade.
Pored toga, uticaj halvinga na rudare može dovesti do promena u rudarskom pejzažu, pri čemu rudari traže lokacije sa nižim troškovima energije ili povoljnijim regulatornim okruženjem. Ovo bi moglo da promeni geografsku sliku rudarskih stanica što dodatno utiče na decentralizaciju mreže.

2025-02-21 19:32:23Europa – das Ganze ist eine wunderbare Idee, \ aber das war der Kommunismus auch. \ Loriot
«Europa hat fertig», könnte man unken, und das wäre nicht einmal sehr verwegen. Mit solch einer Einschätzung stünden wir nicht alleine, denn die Stimmen in diese Richtung mehren sich. Der französische Präsident Emmanuel Macron warnte schon letztes Jahr davor, dass «unser Europa sterben könnte». Vermutlich hatte er dabei andere Gefahren im Kopf als jetzt der ungarische Ministerpräsident Viktor Orbán, der ein «baldiges Ende der EU» prognostizierte. Das Ergebnis könnte allerdings das gleiche sein.
Neben vordergründigen Themenbereichen wie Wirtschaft, Energie und Sicherheit ist das eigentliche Problem jedoch die obskure Mischung aus aufgegebener Souveränität und geschwollener Arroganz, mit der europäische Politiker:innende unterschiedlicher Couleur aufzutreten pflegen. Und das Tüpfelchen auf dem i ist die bröckelnde Legitimation politischer Institutionen dadurch, dass die Stimmen großer Teile der Bevölkerung seit Jahren auf vielfältige Weise ausgegrenzt werden.
Um «UnsereDemokratie» steht es schlecht. Dass seine Mandate immer schwächer werden, merkt natürlich auch unser «Führungspersonal». Entsprechend werden die Maßnahmen zur Gängelung, Überwachung und Manipulation der Bürger ständig verzweifelter. Parallel dazu plustern sich in Paris Macron, Scholz und einige andere noch einmal mächtig in Sachen Verteidigung und «Kriegstüchtigkeit» auf.
Momentan gilt es auch, das Überschwappen covidiotischer und verschwörungsideologischer Auswüchse aus den USA nach Europa zu vermeiden. So ein «MEGA» (Make Europe Great Again) können wir hier nicht gebrauchen. Aus den Vereinigten Staaten kommen nämlich furchtbare Nachrichten. Beispielsweise wurde einer der schärfsten Kritiker der Corona-Maßnahmen kürzlich zum Gesundheitsminister ernannt. Dieser setzt sich jetzt für eine Neubewertung der mRNA-«Impfstoffe» ein, was durchaus zu einem Entzug der Zulassungen führen könnte.
Der europäischen Version von «Verteidigung der Demokratie» setzte der US-Vizepräsident J. D. Vance auf der Münchner Sicherheitskonferenz sein Verständnis entgegen: «Demokratie stärken, indem wir unseren Bürgern erlauben, ihre Meinung zu sagen». Das Abschalten von Medien, das Annullieren von Wahlen oder das Ausschließen von Menschen vom politischen Prozess schütze gar nichts. Vielmehr sei dies der todsichere Weg, die Demokratie zu zerstören.
In der Schweiz kamen seine Worte deutlich besser an als in den meisten europäischen NATO-Ländern. Bundespräsidentin Karin Keller-Sutter lobte die Rede und interpretierte sie als «Plädoyer für die direkte Demokratie». Möglicherweise zeichne sich hier eine außenpolitische Kehrtwende in Richtung integraler Neutralität ab, meint mein Kollege Daniel Funk. Das wären doch endlich mal ein paar gute Nachrichten.
Von der einstigen Idee einer europäischen Union mit engeren Beziehungen zwischen den Staaten, um Konflikte zu vermeiden und das Wohlergehen der Bürger zu verbessern, sind wir meilenweit abgekommen. Der heutige korrupte Verbund unter technokratischer Leitung ähnelt mehr einem Selbstbedienungsladen mit sehr begrenztem Zugang. Die EU-Wahlen im letzten Sommer haben daran ebenso wenig geändert, wie die Bundestagswahl am kommenden Sonntag darauf einen Einfluss haben wird.

2024-01-14 14:52:16bitcoind
decentralizationIt is better to have multiple curator teams, with different vetting processes and release schedules for
bitcoind
than a single one."More eyes on code", "Contribute to Core", "Everybody should audit the code".
All these points repeated again and again fell to Earth on the day it was discovered that Bitcoin Core developers merged a variable name change from "blacklist" to "blocklist" without even discussing or acknowledging the fact that that innocent pull request opened by a sybil account was a social attack.
After a big lot of people manifested their dissatisfaction with that event on Twitter and on GitHub, most Core developers simply ignored everybody's concerns or even personally attacked people who were complaining.
The event has shown that:
1) Bitcoin Core ultimately rests on the hands of a couple maintainers and they decide what goes on the GitHub repository[^pr-merged-very-quickly] and the binary releases that will be downloaded by thousands; 2) Bitcoin Core is susceptible to social attacks; 2) "More eyes on code" don't matter, as these extra eyes can be ignored and dismissed.
Solution:
bitcoind
decentralizationIf usage was spread across 10 different
bitcoind
flavors, the network would be much more resistant to social attacks to a single team.This has nothing to do with the question on if it is better to have multiple different Bitcoin node implementations or not, because here we're basically talking about the same software.
Multiple teams, each with their own release process, their own logo, some subtle changes, or perhaps no changes at all, just a different name for their
bitcoind
flavor, and that's it.Every day or week or month or year, each flavor merges all changes from Bitcoin Core on their own fork. If there's anything suspicious or too leftist (or perhaps too rightist, in case there's a leftist
bitcoind
flavor), maybe they will spot it and not merge.This way we keep the best of both worlds: all software development, bugfixes, improvements goes on Bitcoin Core, other flavors just copy. If there's some non-consensus change whose efficacy is debatable, one of the flavors will merge on their fork and test, and later others -- including Core -- can copy that too. Plus, we get resistant to attacks: in case there is an attack on Bitcoin Core, only 10% of the network would be compromised. the other flavors would be safe.
Run Bitcoin Knots
The first example of a
bitcoind
software that follows Bitcoin Core closely, adds some small changes, but has an independent vetting and release process is Bitcoin Knots, maintained by the incorruptible Luke DashJr.Next time you decide to run
bitcoind
, run Bitcoin Knots instead and contribute tobitcoind
decentralization!

2024-01-14 14:52:16Drivechain
Understanding Drivechain requires a shift from the paradigm most bitcoiners are used to. It is not about "trustlessness" or "mathematical certainty", but game theory and incentives. (Well, Bitcoin in general is also that, but people prefer to ignore it and focus on some illusion of trustlessness provided by mathematics.)
Here we will describe the basic mechanism (simple) and incentives (complex) of "hashrate escrow" and how it enables a 2-way peg between the mainchain (Bitcoin) and various sidechains.
The full concept of "Drivechain" also involves blind merged mining (i.e., the sidechains mine themselves by publishing their block hashes to the mainchain without the miners having to run the sidechain software), but this is much easier to understand and can be accomplished either by the BIP-301 mechanism or by the Spacechains mechanism.
How does hashrate escrow work from the point of view of Bitcoin?
A new address type is created. Anything that goes in that is locked and can only be spent if all miners agree on the Withdrawal Transaction (
WT^
) that will spend it for 6 months. There is one of these special addresses for each sidechain.To gather miners' agreement
bitcoind
keeps track of the "score" of all transactions that could possibly spend from that address. On every block mined, for each sidechain, the miner can use a portion of their coinbase to either increase the score of oneWT^
by 1 while decreasing the score of all others by 1; or they can decrease the score of allWT^
s by 1; or they can do nothing.Once a transaction has gotten a score high enough, it is published and funds are effectively transferred from the sidechain to the withdrawing users.
If a timeout of 6 months passes and the score doesn't meet the threshold, that
WT^
is discarded.What does the above procedure mean?
It means that people can transfer coins from the mainchain to a sidechain by depositing to the special address. Then they can withdraw from the sidechain by making a special withdraw transaction in the sidechain.
The special transaction somehow freezes funds in the sidechain while a transaction that aggregates all withdrawals into a single mainchain
WT^
, which is then submitted to the mainchain miners so they can start voting on it and finally after some months it is published.Now the crucial part: the validity of the
WT^
is not verified by the Bitcoin mainchain rules, i.e., if Bob has requested a withdraw from the sidechain to his mainchain address, but someone publishes a wrongWT^
that instead takes Bob's funds and sends them to Alice's main address there is no way the mainchain will know that. What determines the "validity" of theWT^
is the miner vote score and only that. It is the job of miners to vote correctly -- and for that they may want to run the sidechain node in SPV mode so they can attest for the existence of a reference to theWT^
transaction in the sidechain blockchain (which then ensures it is ok) or do these checks by some other means.What? 6 months to get my money back?
Yes. But no, in practice anyone who wants their money back will be able to use an atomic swap, submarine swap or other similar service to transfer funds from the sidechain to the mainchain and vice-versa. The long delayed withdraw costs would be incurred by few liquidity providers that would gain some small profit from it.
Why bother with this at all?
Drivechains solve many different problems:
It enables experimentation and new use cases for Bitcoin
Issued assets, fully private transactions, stateful blockchain contracts, turing-completeness, decentralized games, some "DeFi" aspects, prediction markets, futarchy, decentralized and yet meaningful human-readable names, big blocks with a ton of normal transactions on them, a chain optimized only for Lighting-style networks to be built on top of it.
These are some ideas that may have merit to them, but were never actually tried because they couldn't be tried with real Bitcoin or inferfacing with real bitcoins. They were either relegated to the shitcoin territory or to custodial solutions like Liquid or RSK that may have failed to gain network effect because of that.
It solves conflicts and infighting
Some people want fully private transactions in a UTXO model, others want "accounts" they can tie to their name and build reputation on top; some people want simple multisig solutions, others want complex code that reads a ton of variables; some people want to put all the transactions on a global chain in batches every 10 minutes, others want off-chain instant transactions backed by funds previously locked in channels; some want to spend, others want to just hold; some want to use blockchain technology to solve all the problems in the world, others just want to solve money.
With Drivechain-based sidechains all these groups can be happy simultaneously and don't fight. Meanwhile they will all be using the same money and contributing to each other's ecosystem even unwillingly, it's also easy and free for them to change their group affiliation later, which reduces cognitive dissonance.
It solves "scaling"
Multiple chains like the ones described above would certainly do a lot to accomodate many more transactions that the current Bitcoin chain can. One could have special Lightning Network chains, but even just big block chains or big-block-mimblewimble chains or whatnot could probably do a good job. Or even something less cool like 200 independent chains just like Bitcoin is today, no extra features (and you can call it "sharding"), just that would already multiply the current total capacity by 200.
Use your imagination.
It solves the blockchain security budget issue
The calculation is simple: you imagine what security budget is reasonable for each block in a world without block subsidy and divide that for the amount of bytes you can fit in a single block: that is the price to be paid in satoshis per byte. In reasonable estimative, the price necessary for every Bitcoin transaction goes to very large amounts, such that not only any day-to-day transaction has insanely prohibitive costs, but also Lightning channel opens and closes are impracticable.
So without a solution like Drivechain you'll be left with only one alternative: pushing Bitcoin usage to trusted services like Liquid and RSK or custodial Lightning wallets. With Drivechain, though, there could be thousands of transactions happening in sidechains and being all aggregated into a sidechain block that would then pay a very large fee to be published (via blind merged mining) to the mainchain. Bitcoin security guaranteed.
It keeps Bitcoin decentralized
Once we have sidechains to accomodate the normal transactions, the mainchain functionality can be reduced to be only a "hub" for the sidechains' comings and goings, and then the maximum block size for the mainchain can be reduced to, say, 100kb, which would make running a full node very very easy.
Can miners steal?
Yes. If a group of coordinated miners are able to secure the majority of the hashpower and keep their coordination for 6 months, they can publish a
WT^
that takes the money from the sidechains and pays to themselves.Will miners steal?
No, because the incentives are such that they won't.
Although it may look at first that stealing is an obvious strategy for miners as it is free money, there are many costs involved:
- The cost of ceasing blind-merged mining returns -- as stealing will kill a sidechain, all the fees from it that miners would be expected to earn for the next years are gone;
- The cost of Bitcoin price going down: If a steal is successful that will mean Drivechains are not safe, therefore Bitcoin is less useful, and miner credibility will also be hurt, which are likely to cause the Bitcoin price to go down, which in turn may kill the miners' businesses and savings;
- The cost of coordination -- assuming miners are just normal businesses, they just want to do their work and get paid, but stealing from a Drivechain will require coordination with other miners to conduct an immoral act in a way that has many pitfalls and is likely to be broken over the months;
- The cost of miners leaving your mining pool: when we talked about "miners" above we were actually talking about mining pools operators, so they must also consider the risk of miners migrating from their mining pool to others as they begin the process of stealing;
- The cost of community goodwill -- when participating in a steal operation, a miner will suffer a ton of backlash from the community. Even if the attempt fails at the end, the fact that it was attempted will contribute to growing concerns over exaggerated miners power over the Bitcoin ecosystem, which may end up causing the community to agree on a hard-fork to change the mining algorithm in the future, or to do something to increase participation of more entities in the mining process (such as development or cheapment of new ASICs), which have a chance of decreasing the profits of current miners.
Another point to take in consideration is that one may be inclined to think a newly-created sidechain or a sidechain with relatively low usage may be more easily stolen from, since the blind merged mining returns from it (point 1 above) are going to be small -- but the fact is also that a sidechain with small usage will also have less money to be stolen from, and since the other costs besides 1 are less elastic at the end it will not be worth stealing from these too.
All of the above consideration are valid only if miners are stealing from good sidechains. If there is a sidechain that is doing things wrong, scamming people, not being used at all, or is full of bugs, for example, that will be perceived as a bad sidechain, and then miners can and will safely steal from it and kill it, which will be perceived as a good thing by everybody.
What do we do if miners steal?
Paul Sztorc has suggested in the past that a user-activated soft-fork could prevent miners from stealing, i.e., most Bitcoin users and nodes issue a rule similar to this one to invalidate the inclusion of a faulty
WT^
and thus cause any miner that includes it in a block to be relegated to their own Bitcoin fork that other nodes won't accept.This suggestion has made people think Drivechain is a sidechain solution backed by user-actived soft-forks for safety, which is very far from the truth. Drivechains must not and will not rely on this kind of soft-fork, although they are possible, as the coordination costs are too high and no one should ever expect these things to happen.
If even with all the incentives against them (see above) miners do still steal from a good sidechain that will mean the failure of the Drivechain experiment. It will very likely also mean the failure of the Bitcoin experiment too, as it will be proven that miners can coordinate to act maliciously over a prolonged period of time regardless of economic and social incentives, meaning they are probably in it just for attacking Bitcoin, backed by nation-states or something else, and therefore no Bitcoin transaction in the mainchain is to be expected to be safe ever again.
Why use this and not a full-blown trustless and open sidechain technology?
Because it is impossible.
If you ever heard someone saying "just use a sidechain", "do this in a sidechain" or anything like that, be aware that these people are either talking about "federated" sidechains (i.e., funds are kept in custody by a group of entities) or they are talking about Drivechain, or they are disillusioned and think it is possible to do sidechains in any other manner.
No, I mean a trustless 2-way peg with correctness of the withdrawals verified by the Bitcoin protocol!
That is not possible unless Bitcoin verifies all transactions that happen in all the sidechains, which would be akin to drastically increasing the blocksize and expanding the Bitcoin rules in tons of ways, i.e., a terrible idea that no one wants.
What about the Blockstream sidechains whitepaper?
Yes, that was a way to do it. The Drivechain hashrate escrow is a conceptually simpler way to achieve the same thing with improved incentives, less junk in the chain, more safety.
Isn't the hashrate escrow a very complex soft-fork?
Yes, but it is much simpler than SegWit. And, unlike SegWit, it doesn't force anything on users, i.e., it isn't a mandatory blocksize increase.
Why should we expect miners to care enough to participate in the voting mechanism?
Because it's in their own self-interest to do it, and it costs very little. Today over half of the miners mine RSK. It's not blind merged mining, it's a very convoluted process that requires them to run a RSK full node. For the Drivechain sidechains, an SPV node would be enough, or maybe just getting data from a block explorer API, so much much simpler.
What if I still don't like Drivechain even after reading this?
That is the entire point! You don't have to like it or use it as long as you're fine with other people using it. The hashrate escrow special addresses will not impact you at all, validation cost is minimal, and you get the benefit of people who want to use Drivechain migrating to their own sidechains and freeing up space for you in the mainchain.

2025-02-19 09:23:17Die «moralische Weltordnung» – eine Art Astrologie. Friedrich Nietzsche
Das Treffen der BRICS-Staaten beim Gipfel im russischen Kasan war sicher nicht irgendein politisches Event. Gastgeber Wladimir Putin habe «Hof gehalten», sagen die Einen, China und Russland hätten ihre Vorstellung einer multipolaren Weltordnung zelebriert, schreiben Andere.
In jedem Fall zeigt die Anwesenheit von über 30 Delegationen aus der ganzen Welt, dass von einer geostrategischen Isolation Russlands wohl keine Rede sein kann. Darüber hinaus haben sowohl die Anreise von UN-Generalsekretär António Guterres als auch die Meldungen und Dementis bezüglich der Beitrittsbemühungen des NATO-Staats Türkei für etwas Aufsehen gesorgt.
Im Spannungsfeld geopolitischer und wirtschaftlicher Umbrüche zeigt die neue Allianz zunehmendes Selbstbewusstsein. In Sachen gemeinsamer Finanzpolitik schmiedet man interessante Pläne. Größere Unabhängigkeit von der US-dominierten Finanzordnung ist dabei ein wichtiges Ziel.
Beim BRICS-Wirtschaftsforum in Moskau, wenige Tage vor dem Gipfel, zählte ein nachhaltiges System für Finanzabrechnungen und Zahlungsdienste zu den vorrangigen Themen. Während dieses Treffens ging der russische Staatsfonds eine Partnerschaft mit dem Rechenzentrumsbetreiber BitRiver ein, um Bitcoin-Mining-Anlagen für die BRICS-Länder zu errichten.
Die Initiative könnte ein Schritt sein, Bitcoin und andere Kryptowährungen als Alternativen zu traditionellen Finanzsystemen zu etablieren. Das Projekt könnte dazu führen, dass die BRICS-Staaten den globalen Handel in Bitcoin abwickeln. Vor dem Hintergrund der Diskussionen über eine «BRICS-Währung» wäre dies eine Alternative zu dem ursprünglich angedachten Korb lokaler Währungen und zu goldgedeckten Währungen sowie eine mögliche Ergänzung zum Zahlungssystem BRICS Pay.
Dient der Bitcoin also der Entdollarisierung? Oder droht er inzwischen, zum Gegenstand geopolitischer Machtspielchen zu werden? Angesichts der globalen Vernetzungen ist es oft schwer zu durchschauen, «was eine Show ist und was im Hintergrund von anderen Strippenziehern insgeheim gesteuert wird». Sicher können Strukturen wie Bitcoin auch so genutzt werden, dass sie den Herrschenden dienlich sind. Aber die Grundeigenschaft des dezentralisierten, unzensierbaren Peer-to-Peer Zahlungsnetzwerks ist ihm schließlich nicht zu nehmen.
Wenn es nach der EZB oder dem IWF geht, dann scheint statt Instrumentalisierung momentan eher der Kampf gegen Kryptowährungen angesagt. Jürgen Schaaf, Senior Manager bei der Europäischen Zentralbank, hat jedenfalls dazu aufgerufen, Bitcoin «zu eliminieren». Der Internationale Währungsfonds forderte El Salvador, das Bitcoin 2021 als gesetzliches Zahlungsmittel eingeführt hat, kürzlich zu begrenzenden Maßnahmen gegen das Kryptogeld auf.
Dass die BRICS-Staaten ein freiheitliches Ansinnen im Kopf haben, wenn sie Kryptowährungen ins Spiel bringen, darf indes auch bezweifelt werden. Im Abschlussdokument bekennen sich die Gipfel-Teilnehmer ausdrücklich zur UN, ihren Programmen und ihrer «Agenda 2030». Ernst Wolff nennt das «eine Bankrotterklärung korrupter Politiker, die sich dem digital-finanziellen Komplex zu 100 Prozent unterwerfen».
