2025-05-09 13:56:57Someone asked for my thoughts, so I’ll share them thoughtfully. I’m not here to dictate how to promote Nostr—I’m still learning about it myself. While I’m not new to Nostr, freedom tech is a newer space for me. I’m skilled at advocating for topics I deeply understand, but freedom tech isn’t my expertise, so take my words with a grain of salt. Nothing I say is set in stone.
Those who need Nostr the most are the ones most vulnerable to censorship on other platforms right now. Reaching them requires real-time awareness of global issues and the dynamic relationships between governments and tech providers, which can shift suddenly. Effective Nostr promoters must grasp this and adapt quickly.
The best messengers are people from or closely tied to these at-risk regions—those who truly understand the local political and cultural dynamics. They can connect with those in need when tensions rise. Ideal promoters are rational, trustworthy, passionate about Nostr, but above all, dedicated to amplifying people’s voices when it matters most.
Forget influencers, corporate-backed figures, or traditional online PR—it comes off as inauthentic, corny, desperate and forced. Nostr’s promotion should be grassroots and organic, driven by a few passionate individuals who believe in Nostr and the communities they serve.
The idea that “people won’t join Nostr due to lack of reach” is nonsense. Everyone knows X’s “reach” is mostly with bots. If humans want real conversations, Nostr is the place. X is great for propaganda, but Nostr is for the authentic voices of the people.
Those spreading Nostr must be so passionate they’re willing to onboard others, which is time-consuming but rewarding for the right person. They’ll need to make Nostr and onboarding a core part of who they are. I see no issue with that level of dedication. I’ve been known to get that way myself at times. It’s fun for some folks.
With love, I suggest not adding Bitcoin promotion with Nostr outreach. Zaps already integrate that element naturally. (Still promote within the Bitcoin ecosystem, but this is about reaching vulnerable voices who needed Nostr yesterday.)
To promote Nostr, forget conventional strategies. “Influencers” aren’t the answer. “Influencers” are not the future. A trusted local community member has real influence—reach them. Connect with people seeking Nostr’s benefits but lacking the technical language to express it. This means some in the Nostr community might need to step outside of the Bitcoin bubble, which is uncomfortable but necessary. Thank you in advance to those who are willing to do that.
I don’t know who is paid to promote Nostr, if anyone. This piece isn’t shade. But it’s exhausting to see innocent voices globally silenced on corporate platforms like X while Nostr exists. Last night, I wondered: how many more voices must be censored before the Nostr community gets uncomfortable and thinks creatively to reach the vulnerable?
A warning: the global need for censorship-resistant social media is undeniable. If Nostr doesn’t make itself known, something else will fill that void. Let’s start this conversation.

2025-05-01 01:51:10Please respect Virginia Giuffre’s memory by refraining from asking about the circumstances or theories surrounding her passing.
Since Virginia Giuffre’s death, I’ve reflected on what she would want me to say or do. This piece is my attempt to honor her legacy.
When I first spoke with Virginia, I was struck by her unshakable hope. I had grown cynical after years in the anti-human trafficking movement, worn down by a broken system and a government that often seemed complicit. But Virginia’s passion, creativity, and belief that survivors could be heard reignited something in me. She reminded me of my younger, more hopeful self. Instead of warning her about the challenges ahead, I let her dream big, unburdened by my own disillusionment. That conversation changed me for the better, and following her lead led to meaningful progress.
Virginia was one of the bravest people I’ve ever known. As a survivor of Epstein, Maxwell, and their co-conspirators, she risked everything to speak out, taking on some of the world’s most powerful figures.
She loved when I said, “Epstein isn’t the only Epstein.” This wasn’t just about one man—it was a call to hold all abusers accountable and to ensure survivors find hope and healing.
The Epstein case often gets reduced to sensational details about the elite, but that misses the bigger picture. Yes, we should be holding all of the co-conspirators accountable, we must listen to the survivors’ stories. Their experiences reveal how predators exploit vulnerabilities, offering lessons to prevent future victims.
You’re not powerless in this fight. Educate yourself about trafficking and abuse—online and offline—and take steps to protect those around you. Supporting survivors starts with small, meaningful actions. Free online resources can guide you in being a safe, supportive presence.
When high-profile accusations arise, resist snap judgments. Instead of dismissing survivors as “crazy,” pause to consider the trauma they may be navigating. Speaking out or coping with abuse is never easy. You don’t have to believe every claim, but you can refrain from attacking accusers online.
Society also fails at providing aftercare for survivors. The government, often part of the problem, won’t solve this. It’s up to us. Prevention is critical, but when abuse occurs, step up for your loved ones and community. Protect the vulnerable. it’s a challenging but a rewarding journey.
If you’re contributing to Nostr, you’re helping build a censorship resistant platform where survivors can share their stories freely, no matter how powerful their abusers are. Their voices can endure here, offering strength and hope to others. This gives me great hope for the future.
Virginia Giuffre’s courage was a gift to the world. It was an honor to know and serve her. She will be deeply missed. My hope is that her story inspires others to take on the powerful.

2025-04-28 00:48:57I have been recently building NFDB, a new relay DB. This post is meant as a short overview.
Regular relays have challenges
Current relay software have significant challenges, which I have experienced when hosting Nostr.land: - Scalability is only supported by adding full replicas, which does not scale to large relays. - Most relays use slow databases and are not optimized for large scale usage. - Search is near-impossible to implement on standard relays. - Privacy features such as NIP-42 are lacking. - Regular DB maintenance tasks on normal relays require extended downtime. - Fault-tolerance is implemented, if any, using a load balancer, which is limited. - Personalization and advanced filtering is not possible. - Local caching is not supported.
NFDB: A scalable database for large relays
NFDB is a new database meant for medium-large scale relays, built on FoundationDB that provides: - Near-unlimited scalability - Extended fault tolerance - Instant loading - Better search - Better personalization - and more.
Search
NFDB has extended search capabilities including: - Semantic search: Search for meaning, not words. - Interest-based search: Highlight content you care about. - Multi-faceted queries: Easily filter by topic, author group, keywords, and more at the same time. - Wide support for event kinds, including users, articles, etc.
Personalization
NFDB allows significant personalization: - Customized algorithms: Be your own algorithm. - Spam filtering: Filter content to your WoT, and use advanced spam filters. - Topic mutes: Mute topics, not keywords. - Media filtering: With Nostr.build, you will be able to filter NSFW and other content - Low data mode: Block notes that use high amounts of cellular data. - and more
Other
NFDB has support for many other features such as: - NIP-42: Protect your privacy with private drafts and DMs - Microrelays: Easily deploy your own personal microrelay - Containers: Dedicated, fast storage for discoverability events such as relay lists
Calcite: A local microrelay database
Calcite is a lightweight, local version of NFDB that is meant for microrelays and caching, meant for thousands of personal microrelays.
Calcite HA is an additional layer that allows live migration and relay failover in under 30 seconds, providing higher availability compared to current relays with greater simplicity. Calcite HA is enabled in all Calcite deployments.
For zero-downtime, NFDB is recommended.
Noswhere SmartCache
Relays are fixed in one location, but users can be anywhere.
Noswhere SmartCache is a CDN for relays that dynamically caches data on edge servers closest to you, allowing: - Multiple regions around the world - Improved throughput and performance - Faster loading times
routerd
routerd
is a custom load-balancer optimized for Nostr relays, integrated with SmartCache.routerd
is specifically integrated with NFDB and Calcite HA to provide fast failover and high performance.Ending notes
NFDB is planned to be deployed to Nostr.land in the coming weeks.
A lot more is to come. 👀️️️️️️

2025-04-26 10:16:21O Contexto Legal Brasileiro e o Consentimento
No ordenamento jurídico brasileiro, o consentimento do ofendido pode, em certas circunstâncias, afastar a ilicitude de um ato que, sem ele, configuraria crime (como lesão corporal leve, prevista no Art. 129 do Código Penal). Contudo, o consentimento tem limites claros: não é válido para bens jurídicos indisponíveis, como a vida, e sua eficácia é questionável em casos de lesões corporais graves ou gravíssimas.
A prática de BDSM consensual situa-se em uma zona complexa. Em tese, se ambos os parceiros são adultos, capazes, e consentiram livre e informadamente nos atos praticados, sem que resultem em lesões graves permanentes ou risco de morte não consentido, não haveria crime. O desafio reside na comprovação desse consentimento, especialmente se uma das partes, posteriormente, o negar ou alegar coação.
A Lei Maria da Penha (Lei nº 11.340/2006)
A Lei Maria da Penha é um marco fundamental na proteção da mulher contra a violência doméstica e familiar. Ela estabelece mecanismos para coibir e prevenir tal violência, definindo suas formas (física, psicológica, sexual, patrimonial e moral) e prevendo medidas protetivas de urgência.
Embora essencial, a aplicação da lei em contextos de BDSM pode ser delicada. Uma alegação de violência por parte da mulher, mesmo que as lesões ou situações decorram de práticas consensuais, tende a receber atenção prioritária das autoridades, dada a presunção de vulnerabilidade estabelecida pela lei. Isso pode criar um cenário onde o parceiro masculino enfrenta dificuldades significativas em demonstrar a natureza consensual dos atos, especialmente se não houver provas robustas pré-constituídas.
Outros riscos:
Lesão corporal grave ou gravíssima (art. 129, §§ 1º e 2º, CP), não pode ser justificada pelo consentimento, podendo ensejar persecução penal.
Crimes contra a dignidade sexual (arts. 213 e seguintes do CP) são de ação pública incondicionada e independem de representação da vítima para a investigação e denúncia.
Riscos de Falsas Acusações e Alegação de Coação Futura
Os riscos para os praticantes de BDSM, especialmente para o parceiro que assume o papel dominante ou que inflige dor/restrição (frequentemente, mas não exclusivamente, o homem), podem surgir de diversas frentes:
- Acusações Externas: Vizinhos, familiares ou amigos que desconhecem a natureza consensual do relacionamento podem interpretar sons, marcas ou comportamentos como sinais de abuso e denunciar às autoridades.
- Alegações Futuras da Parceira: Em caso de término conturbado, vingança, arrependimento ou mudança de perspectiva, a parceira pode reinterpretar as práticas passadas como abuso e buscar reparação ou retaliação através de uma denúncia. A alegação pode ser de que o consentimento nunca existiu ou foi viciado.
- Alegação de Coação: Uma das formas mais complexas de refutar é a alegação de que o consentimento foi obtido mediante coação (física, moral, psicológica ou econômica). A parceira pode alegar, por exemplo, que se sentia pressionada, intimidada ou dependente, e que seu "sim" não era genuíno. Provar a ausência de coação a posteriori é extremamente difícil.
- Ingenuidade e Vulnerabilidade Masculina: Muitos homens, confiando na dinâmica consensual e na parceira, podem negligenciar a necessidade de precauções. A crença de que "isso nunca aconteceria comigo" ou a falta de conhecimento sobre as implicações legais e o peso processual de uma acusação no âmbito da Lei Maria da Penha podem deixá-los vulneráveis. A presença de marcas físicas, mesmo que consentidas, pode ser usada como evidência de agressão, invertendo o ônus da prova na prática, ainda que não na teoria jurídica.
Estratégias de Prevenção e Mitigação
Não existe um método infalível para evitar completamente o risco de uma falsa acusação, mas diversas medidas podem ser adotadas para construir um histórico de consentimento e reduzir vulnerabilidades:
- Comunicação Explícita e Contínua: A base de qualquer prática BDSM segura é a comunicação constante. Negociar limites, desejos, palavras de segurança ("safewords") e expectativas antes, durante e depois das cenas é crucial. Manter registros dessas negociações (e-mails, mensagens, diários compartilhados) pode ser útil.
-
Documentação do Consentimento:
-
Contratos de Relacionamento/Cena: Embora a validade jurídica de "contratos BDSM" seja discutível no Brasil (não podem afastar normas de ordem pública), eles servem como forte evidência da intenção das partes, da negociação detalhada de limites e do consentimento informado. Devem ser claros, datados, assinados e, idealmente, reconhecidos em cartório (para prova de data e autenticidade das assinaturas).
-
Registros Audiovisuais: Gravar (com consentimento explícito para a gravação) discussões sobre consentimento e limites antes das cenas pode ser uma prova poderosa. Gravar as próprias cenas é mais complexo devido a questões de privacidade e potencial uso indevido, mas pode ser considerado em casos específicos, sempre com consentimento mútuo documentado para a gravação.
Importante: a gravação deve ser com ciência da outra parte, para não configurar violação da intimidade (art. 5º, X, da Constituição Federal e art. 20 do Código Civil).
-
-
Testemunhas: Em alguns contextos de comunidade BDSM, a presença de terceiros de confiança durante negociações ou mesmo cenas pode servir como testemunho, embora isso possa alterar a dinâmica íntima do casal.
- Estabelecimento Claro de Limites e Palavras de Segurança: Definir e respeitar rigorosamente os limites (o que é permitido, o que é proibido) e as palavras de segurança é fundamental. O desrespeito a uma palavra de segurança encerra o consentimento para aquele ato.
- Avaliação Contínua do Consentimento: O consentimento não é um cheque em branco; ele deve ser entusiástico, contínuo e revogável a qualquer momento. Verificar o bem-estar do parceiro durante a cena ("check-ins") é essencial.
- Discrição e Cuidado com Evidências Físicas: Ser discreto sobre a natureza do relacionamento pode evitar mal-entendidos externos. Após cenas que deixem marcas, é prudente que ambos os parceiros estejam cientes e de acordo, talvez documentando por fotos (com data) e uma nota sobre a consensualidade da prática que as gerou.
- Aconselhamento Jurídico Preventivo: Consultar um advogado especializado em direito de família e criminal, com sensibilidade para dinâmicas de relacionamento alternativas, pode fornecer orientação personalizada sobre as melhores formas de documentar o consentimento e entender os riscos legais específicos.
Observações Importantes
- Nenhuma documentação substitui a necessidade de consentimento real, livre, informado e contínuo.
- A lei brasileira protege a "integridade física" e a "dignidade humana". Práticas que resultem em lesões graves ou que violem a dignidade de forma não consentida (ou com consentimento viciado) serão ilegais, independentemente de qualquer acordo prévio.
- Em caso de acusação, a existência de documentação robusta de consentimento não garante a absolvição, mas fortalece significativamente a defesa, ajudando a demonstrar a natureza consensual da relação e das práticas.
-
A alegação de coação futura é particularmente difícil de prevenir apenas com documentos. Um histórico consistente de comunicação aberta (whatsapp/telegram/e-mails), respeito mútuo e ausência de dependência ou controle excessivo na relação pode ajudar a contextualizar a dinâmica como não coercitiva.
-
Cuidado com Marcas Visíveis e Lesões Graves Práticas que resultam em hematomas severos ou lesões podem ser interpretadas como agressão, mesmo que consentidas. Evitar excessos protege não apenas a integridade física, mas também evita questionamentos legais futuros.
O que vem a ser consentimento viciado
No Direito, consentimento viciado é quando a pessoa concorda com algo, mas a vontade dela não é livre ou plena — ou seja, o consentimento existe formalmente, mas é defeituoso por alguma razão.
O Código Civil brasileiro (art. 138 a 165) define várias formas de vício de consentimento. As principais são:
Erro: A pessoa se engana sobre o que está consentindo. (Ex.: A pessoa acredita que vai participar de um jogo leve, mas na verdade é exposta a práticas pesadas.)
Dolo: A pessoa é enganada propositalmente para aceitar algo. (Ex.: Alguém mente sobre o que vai acontecer durante a prática.)
Coação: A pessoa é forçada ou ameaçada a consentir. (Ex.: "Se você não aceitar, eu termino com você" — pressão emocional forte pode ser vista como coação.)
Estado de perigo ou lesão: A pessoa aceita algo em situação de necessidade extrema ou abuso de sua vulnerabilidade. (Ex.: Alguém em situação emocional muito fragilizada é induzida a aceitar práticas que normalmente recusaria.)
No contexto de BDSM, isso é ainda mais delicado: Mesmo que a pessoa tenha "assinado" um contrato ou dito "sim", se depois ela alegar que seu consentimento foi dado sob medo, engano ou pressão psicológica, o consentimento pode ser considerado viciado — e, portanto, juridicamente inválido.
Isso tem duas implicações sérias:
-
O crime não se descaracteriza: Se houver vício, o consentimento é ignorado e a prática pode ser tratada como crime normal (lesão corporal, estupro, tortura, etc.).
-
A prova do consentimento precisa ser sólida: Mostrando que a pessoa estava informada, lúcida, livre e sem qualquer tipo de coação.
Consentimento viciado é quando a pessoa concorda formalmente, mas de maneira enganada, forçada ou pressionada, tornando o consentimento inútil para efeitos jurídicos.
Conclusão
Casais que praticam BDSM consensual no Brasil navegam em um terreno que exige não apenas confiança mútua e comunicação excepcional, mas também uma consciência aguçada das complexidades legais e dos riscos de interpretações equivocadas ou acusações mal-intencionadas. Embora o BDSM seja uma expressão legítima da sexualidade humana, sua prática no Brasil exige responsabilidade redobrada. Ter provas claras de consentimento, manter a comunicação aberta e agir com prudência são formas eficazes de se proteger de falsas alegações e preservar a liberdade e a segurança de todos os envolvidos. Embora leis controversas como a Maria da Penha sejam "vitais" para a proteção contra a violência real, os praticantes de BDSM, e em particular os homens nesse contexto, devem adotar uma postura proativa e prudente para mitigar os riscos inerentes à potencial má interpretação ou instrumentalização dessas práticas e leis, garantindo que a expressão de sua consensualidade esteja resguardada na medida do possível.
Importante: No Brasil, mesmo com tudo isso, o Ministério Público pode denunciar por crime como lesão corporal grave, estupro ou tortura, independente de consentimento. Então a prudência nas práticas é fundamental.

2025-02-21 18:15:52"Malcolm Forbes recounts that a lady, wearing a faded cotton dress, and her husband, dressed in an old handmade suit, stepped off a train in Boston, USA, and timidly made their way to the office of the president of Harvard University. They had come from Palo Alto, California, and had not scheduled an appointment. The secretary, at a glance, thought that those two, looking like country bumpkins, had no business at Harvard.
— We want to speak with the president — the man said in a low voice.
— He will be busy all day — the secretary replied curtly.
— We will wait.
The secretary ignored them for hours, hoping the couple would finally give up and leave. But they stayed there, and the secretary, somewhat frustrated, decided to bother the president, although she hated doing that.
— If you speak with them for just a few minutes, maybe they will decide to go away — she said.
The president sighed in irritation but agreed. Someone of his importance did not have time to meet people like that, but he hated faded dresses and tattered suits in his office. With a stern face, he went to the couple.
— We had a son who studied at Harvard for a year — the woman said. — He loved Harvard and was very happy here, but a year ago he died in an accident, and we would like to erect a monument in his honor somewhere on campus.— My lady — said the president rudely —, we cannot erect a statue for every person who studied at Harvard and died; if we did, this place would look like a cemetery.
— Oh, no — the lady quickly replied. — We do not want to erect a statue. We would like to donate a building to Harvard.
The president looked at the woman's faded dress and her husband's old suit and exclaimed:
— A building! Do you have even the faintest idea of how much a building costs? We have more than seven and a half million dollars' worth of buildings here at Harvard.
The lady was silent for a moment, then said to her husband:
— If that’s all it costs to found a university, why don’t we have our own?
The husband agreed.
The couple, Leland Stanford, stood up and left, leaving the president confused. Traveling back to Palo Alto, California, they established there Stanford University, the second-largest in the world, in honor of their son, a former Harvard student."

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.

2025-02-15 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.

2025-02-14 23:24:37intro
The Russian state made me a Bitcoiner. In 1991, it devalued my grandmother's hard-earned savings. She worked tirelessly in the kitchen of a dining car on the Moscow–Warsaw route. Everything she had saved for my sister and me to attend university vanished overnight. This story is similar to what many experienced, including Wences Casares. The pain and injustice of that time became my first lessons about the fragility of systems and the value of genuine, incorruptible assets, forever changing my perception of money and my trust in government promises.
In 2014, I was living in Moscow, running a trading business, and frequently traveling to China. One day, I learned about the Cypriot banking crisis and the possibility of moving money through some strange thing called Bitcoin. At the time, I didn’t give it much thought. Returning to the idea six months later, as a business-oriented geek, I eagerly began studying the topic and soon dove into it seriously.
I spent half a year reading articles on a local online journal, BitNovosti, actively participating in discussions, and eventually joined the editorial team as a translator. That’s how I learned about whitepapers, decentralization, mining, cryptographic keys, and colored coins. About Satoshi Nakamoto, Silk Road, Mt. Gox, and BitcoinTalk. Over time, I befriended the journal’s owner and, leveraging my management experience, later became an editor. I was drawn to the crypto-anarchist stance and commitment to decentralization principles. We wrote about the economic, historical, and social preconditions for Bitcoin’s emergence, and it was during this time that I fully embraced the idea.
It got to the point where I sold my apartment and, during the market's downturn, bought 50 bitcoins, just after the peak price of $1,200 per coin. That marked the beginning of my first crypto winter. As an editor, I organized workflows, managed translators, developed a YouTube channel, and attended conferences in Russia and Ukraine. That’s how I learned about Wences Casares and even wrote a piece about him. I also met Mikhail Chobanyan (Ukrainian exchange Kuna), Alexander Ivanov (Waves project), Konstantin Lomashuk (Lido project), and, of course, Vitalik Buterin. It was a time of complete immersion, 24/7, and boundless hope.
After moving to the United States, I expected the industry to grow rapidly, attended events, but the introduction of BitLicense froze the industry for eight years. By 2017, it became clear that the industry was shifting toward gambling and creating tokens for the sake of tokens. I dismissed this idea as unsustainable. Then came a new crypto spring with the hype around beautiful NFTs – CryptoPunks and apes.
I made another attempt – we worked on a series called Digital Nomad Country Club, aimed at creating a global project. The proceeds from selling images were intended to fund the development of business tools for people worldwide. However, internal disagreements within the team prevented us from completing the project.
With Trump’s arrival in 2025, hope was reignited. I decided that it was time to create a project that society desperately needed. As someone passionate about history, I understood that destroying what exists was not the solution, but leaving everything as it was also felt unacceptable. You can’t destroy the system, as the fiery crypto-anarchist voices claimed.
With an analytical mindset (IQ 130) and a deep understanding of the freest societies, I realized what was missing—not only in Russia or the United States but globally—a Bitcoin-native system for tracking debts and financial interactions. This could return control of money to ordinary people and create horizontal connections parallel to state systems. My goal was to create, if not a Bitcoin killer app, then at least to lay its foundation.
At the inauguration event in New York, I rediscovered the Nostr project. I realized it was not only technologically simple and already quite popular but also perfectly aligned with my vision. For the past month and a half, using insights and experience gained since 2014, I’ve been working full-time on this project.

2025-02-13 06:16:49My favorite line in any Marvel movie ever is in “Captain America.” After Captain America launches seemingly a hopeless assault on Red Skull’s base and is captured, we get this line:
“Arrogance may not be a uniquely American trait, but I must say, you do it better than anyone.”
Yesterday, I came across a comment on the song Devil Went Down to Georgia that had a very similar feel to it:
America has seemingly always been arrogant, in a uniquely American way. Manifest Destiny, for instance. The rest of the world is aware of this arrogance, and mocks Americans for it. A central point in modern US politics is the deriding of racist, nationalist, supremacist Americans.
That’s not what I see. I see American Arrogance as not only a beautiful statement about what it means to be American. I see it as an ode to the greatness of humanity in its purest form.
For most countries, saying “our nation is the greatest” is, in fact, twinged with some level of racism. I still don’t have a problem with it. Every group of people should be allowed to feel pride in their accomplishments. The destruction of the human spirit since the end of World War 2, where greatness has become a sin and weakness a virtue, has crushed the ability of people worldwide to strive for excellence.
But I digress. The fears of racism and nationalism at least have a grain of truth when applied to other nations on the planet. But not to America.
That’s because the definition of America, and the prototype of an American, has nothing to do with race. The definition of Americanism is freedom. The founding of America is based purely on liberty. On the God-given rights of every person to live life the way they see fit.
American Arrogance is not a statement of racial superiority. It’s barely a statement of national superiority (though it absolutely is). To me, when an American comments on the greatness of America, it’s a statement about freedom. Freedom will always unlock the greatness inherent in any group of people. Americans are definitionally better than everyone else, because Americans are freer than everyone else. (Or, at least, that’s how it should be.)
In Devil Went Down to Georgia, Johnny is approached by the devil himself. He is challenged to a ridiculously lopsided bet: a golden fiddle versus his immortal soul. He acknowledges the sin in accepting such a proposal. And yet he says, “God, I know you told me not to do this. But I can’t stand the affront to my honor. I am the greatest. The devil has nothing on me. So God, I’m gonna sin, but I’m also gonna win.”

@ daa41bed:88f54153
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.

2025-02-05 17:47:16I got into a friendly discussion on X regarding health insurance. The specific question was how to deal with health insurance companies (presumably unfairly) denying claims? My answer, as usual: get government out of it!
The US healthcare system is essentially the worst of both worlds:
- Unlike full single payer, individuals incur high costs
- Unlike a true free market, regulation causes increases in costs and decreases competition among insurers
I'm firmly on the side of moving towards the free market. (And I say that as someone living under a single payer system now.) Here's what I would do:
- Get rid of tax incentives that make health insurance tied to your employer, giving individuals back proper freedom of choice.
- Reduce regulations significantly.
-
In the short term, some people will still get rejected claims and other obnoxious behavior from insurance companies. We address that in two ways:
- Due to reduced regulations, new insurance companies will be able to enter the market offering more reliable coverage and better rates, and people will flock to them because they have the freedom to make their own choices.
- Sue the asses off of companies that reject claims unfairly. And ideally, as one of the few legitimate roles of government in all this, institute new laws that limit the ability of fine print to allow insurers to escape their responsibilities. (I'm hesitant that the latter will happen due to the incestuous relationship between Congress/regulators and insurers, but I can hope.)
Will this magically fix everything overnight like politicians normally promise? No. But it will allow the market to return to a healthy state. And I don't think it will take long (order of magnitude: 5-10 years) for it to come together, but that's just speculation.
And since there's a high correlation between those who believe government can fix problems by taking more control and demanding that only credentialed experts weigh in on a topic (both points I strongly disagree with BTW): I'm a trained actuary and worked in the insurance industry, and have directly seen how government regulation reduces competition, raises prices, and harms consumers.
And my final point: I don't think any prior art would be a good comparison for deregulation in the US, it's such a different market than any other country in the world for so many reasons that lessons wouldn't really translate. Nonetheless, I asked Grok for some empirical data on this, and at best the results of deregulation could be called "mixed," but likely more accurately "uncertain, confused, and subject to whatever interpretation anyone wants to apply."

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.
To learn more about the project, you can visit: Designathon website: https://event.bitcoin.design/#project-recj4SVNLLkuWHpKq Discord channel: https://discord.com/channels/903125802726596648/1369200271632236574 Previous SN posts: https://stacker.news/items/974489/r/DeSign_r and https://stacker.news/items/974488/r/DeSign_r
Stay tuned, more will be happening this coming week

@ 502ab02a:a2860397
2025-05-12 03:11:06สัปดาห์ที่ผ่านมา เราพักผ่อนย้อนไปเพื่อทำความเข้าใจต้นเหตุของซีรีส์นี้กันแล้วนะครับ ทีนี้เราจะมาสนทนากันต่อจากที่ค้างคาไว้กันครับ
ย้อนกลับไปเมื่อราวทศวรรษ 1970-1980 เป็นยุคที่โลกยังเชื่อว่า “ไขมัน” คือผู้ร้ายตัวจริงในวงการสุขภาพ ปิรามิดอาหารจาก USDA จึงถือกำเนิดขึ้น โดยมีฐานล่างกว้างใหญ่เต็มไปด้วยข้าว แป้ง ซีเรียล พาสต้า และขนมปัง เรียกรวมว่า “กลุ่มคาร์โบไฮเดรต” และถูกวางให้เป็นเสาหลักของอาหารประจำวัน ภายใต้แนวคิดว่าให้พลังงานสูง ไขมันต่ำ ดีต่อหัวใจ และเหมาะกับการเลี้ยงประชากรโลกที่เพิ่มขึ้นอย่างรวดเร็ว
แต่ความจริงที่เปิดเผยภายหลังคือ ปิรามิดอาหารนี้มิได้เกิดจากวิทยาศาสตร์บริสุทธิ์ หากแต่เกิดจากกระบวนการ “เปิดประมูลนโยบาย” โดยกลุ่มอุตสาหกรรมเกษตรรายใหญ่ ซึ่งต้องการระบายผลผลิตคาร์โบไฮเดรตจำนวนมหาศาลจากข้าวโพด ข้าวสาลี และถั่วเหลืองที่รัฐบาลอเมริกันอุดหนุนให้เพาะปลูกเกินความจำเป็น (ดูรายงาน PBS: The Food Pyramid) หน้าที่จัดสรรนี้จึงอยู่ภายใต้ USDA หรือ กระทรวงเกษตรสหรัฐอเมริกา
ขณะที่ผู้คนถูกสอนให้หลีกเลี่ยงไขมัน โปรตีนสัตว์ และหันมากินซีเรียลเป็นอาหารเช้า ผลิตภัณฑ์ไขมันต่ำแทบทุกชนิดกลับต้องเติมน้ำตาลและแป้งเพื่อให้มีรสชาติ นำไปสู่การระบาดของโรคอ้วน เบาหวาน ความดัน และ NCD ทั่วโลก ที่เราเพิ่งจะเข้าใจกันวันนี้ว่ามีรากมาจาก “ปิรามิดคาร์บ” นั่นเอง
คำถามคือ ทำไมการกำหนดอาหารของอเมริกา (ซึ่งแน่นอนว่าแพร่กระจายไปทั่วโลกภายใต้ข้อกำหนดเดียวกัน) จึงเกิดขึ้นจาก "กระทรวงเกษตรสหรัฐอเมริกา" ไม่ใช่ หน่วยงานทางวิทยาศาสตร์ หรือ การแพทย์
หรือเพราะ “อาหาร” ในอเมริกา ไม่ได้เริ่มจากคำว่า “สุขภาพ” แต่เริ่มจาก “เศรษฐกิจ”
ย้อนกลับไปช่วงต้นศตวรรษที่ 20 โดยเฉพาะหลังสงครามโลกครั้งที่สอง สหรัฐฯ ต้องการฟื้นฟูเศรษฐกิจและผลักดันภาคการเกษตรให้โตอย่างรวดเร็ว โดยเฉพาะสินค้าพืชเชิงอุตสาหกรรม เช่น ข้าวโพด ข้าวสาลี ถั่วเหลือง นม และเนื้อจากฟาร์มอุตสาหกรรม และปากท้องของเกษตรกรคือฐานเสียงสำคัญในทุกๆรัฐบาล ดังนั้น USDA ซึ่งเป็นหน่วยงานที่ตั้งขึ้นเพื่อดูแลเกษตรกร จึงรับบทผู้ออก “แนวทางโภชนาการ” โดยเน้นว่า
อาหารอะไรที่ เกษตรกรผลิตได้เยอะ ก็เอามาดันให้ประชาชนกินเยอะ อาหารอะไรที่ ราคาถูก ผลิตได้เร็ว ก็นำมาใส่ไว้ฐานล่างของพีระมิด ให้ประชาชนกินเยอะ อาหารอะไรที่ มีอุตสาหกรรมอยู่เบื้องหลัง ก็เปิดประมูลให้มีบทบาทมากในการล็อบบี้นโยบาย ให้ประชาชนกินเยอะ
พูดง่ายๆ ก็คือ นโยบายอาหารอเมริกา ไม่ได้ออกโดยนักวิทยาศาสตร์หรือนักโภชนาการที่ไม่มีผลประโยชน์ทับซ้อน แต่มาจาก “ข้าราชการสายเกษตร+กลุ่มทุน” ที่ต้องการให้ภาคการเกษตรมีกำไรอย่างต่อเนื่อง และอย่าลืมว่า อเมริกา = โลก
แล้วหน่วยงานด้านวิทยาศาสตร์หรือแพทย์ เช่น NIH (National Institutes of Health) หรือ CDC (Centers for Disease Control and Prevention) หล่ะ แน่นอนครับว่ามีข้อมูลอยุ่ว่าก็มีสิทธิ์เสนอแนะอยู่บ้างแต่ทั้งหมดนี้ ไม่มีอำนาจออกนโยบายหลักที่ใช้จริงกับประชาชน ส่วนใหญ่แค่ให้ข้อมูลวิชาการ ซึ่งมักจะถูกลดทอนหรือละเลยเมื่อนโยบายจริงถูกเขียนขึ้นโดย USDA ในที่สุด
เมื่อเสียงของการตั้งคำถามเริ่มดังกว่าเสียงโฆษณา ขบวนการ “Low Carb” ก็เริ่มตั้งหลักและขยายวงกว้างอย่างเงียบๆ งานวิจัยใหม่ๆ เริ่มบ่งชี้ว่า “น้ำตาลและแป้ง” โดยเฉพาะแป้งแปรรูป คือภัยเงียบที่ส่งผลต่อการอักเสบเรื้อรัง ภาวะดื้ออินซูลิน และเมตาบอลิกซินโดรม จนกระทั่งช่วงต้นทศวรรษ 2010 เป็นต้นมา อาหารแนว “ลดคาร์บ เพิ่มไขมันดี เพิ่มโปรตีน” ก็กลายเป็นกระแสหลักขึ้นมา
ตอนนั้นหลายคนคิดว่า “พวกเราชนะแล้ว” โลกกลับมาฟังเสียงสุขภาพที่แท้จริง โปรตีนกลายเป็นคำตอบใหม่แห่งยุค
แต่มึงเอ๊ยยยยยย... เกมอาจไม่ได้จบตรงนั้น
เพราะในวันที่ประชาชนเริ่มหลีกหนีคาร์บ กลุ่มทุนอาหารข้ามชาติที่เคยวางรากอยู่ในอุตสาหกรรมแป้ง ได้ค่อยๆ แปรทิศ ย้ายการลงทุนไปสู่ “โปรตีนทางเลือก” รอไว้นานแล้วโดยที่เราไม่รู้ตัว ทั้งอาหารพืชแปรรูปอย่าง texture ถั่วเหลือง (TVP), โปรตีนจุลินทรีย์, เนื้อปลูกจากห้องแลบ ไปจนถึง “ไข่” และ “นม” ที่ไม่ได้มาจากสัตว์ โปรตีนสังเคราะห์ที่ผลิตโดยระบบชีวภาพวิศวกรรม (synthetic biology) ซึ่งได้รับเงินทุนจากบริษัทยักษ์ใหญ่อย่างต่อเนื่องตลอดสิบปีที่ผ่านมา
พอถึงวันโปรตีนกลายเป็นเทรนด์ เขาก็เข้ามาเป็นเจ้าของเทรนด์เป็นที่เรียบร้อยแล้ว พร้อมทุกอย่างแล้ว คำถามคือ ใครกันแน่ที่เป็น Trend Setter
โปรตีนจึงไม่ใช่เพียง “สารอาหาร” อีกต่อไป แต่มันคือ “สินค้าอนาคต” ที่สามารถควบคุมแหล่งผลิต แหล่งพันธุ์ เทคโนโลยีการแปรรูป และการกระจายผ่านแพลตฟอร์มค้าปลีกทั่วโลก และถ้าคุณสังเกต จะเห็นว่าไม่มีใครพูดถึง “คาร์บทางเลือก” หรือ "คาร์บเข้มข้น" หรือ "คาร์บที่ไม่ต้องใช้พืช" แม้แต่นิด ทั้งที่ในทางหลักการก็สามารถคิดค้นได้ไม่ต่างกัน แปลว่า พวกเขาไม่ได้แค่อยาก “เลิกขายคาร์บ” แต่กำลัง “เปลี่ยนสินค้าหลักใหม่” ให้ไปอยู่ในกลุ่มที่พวกเขาควบคุมได้ทั้งหมด แค่เอาคำว่า "โปรตีน" ขึ้นมาเป็นฉากหน้าไว้ก่อน
เริ่มเห็นภาพไหมครับ จากคาร์บที่เคยถูกบิดเบือน กลายมาเป็นโปรตีนที่ถูกเสนอให้เรายินดีรับอย่างไม่ตั้งคำถาม
“โปรตีนอนาคต” ดูเหมือนจะเป็นทางเลือก แต่จริงๆ แล้วอาจเป็นกับดักหรือเปล่า
วันนี้ที่หลายคนเฝ้ามองชัยชนะของผู้คนในการล้ม “ปิรามิดคาร์บ” แต่ไม่ทันเห็นว่ากำลังถูกลากเข้าสู่ “หอคอยโปรตีนจำลอง” ที่พวกเขาสร้างขึ้นใหม่ ด้วยบรรจุภัณฑ์สวยหรู คำว่า "รักษ์โลก" "ปลอดภัย" และ "ยั่งยืน" แต่แท้จริงคือห่วงโซ่ที่มัดให้เราเป็นเพียง “ผู้บริโภค” ที่ไม่มีทางรู้ว่าอาหารของเรามาจากธรรมชาติหรือห้องแลบอีกต่อไป เรากลายเป็นหนูที่ย้ายจากกล่องวงกตหนึ่ง มายังอีกกล่องวงกตหนึ่งหรือเปล่า เป็นคำถามที่ยังต้องตอบต่อไป
เฮียไม่ได้มาเพื่อหวาดระแวงนะครับ เพราะในเกมอำนาจอาหาร ไม่มีใครยอมเสียพื้นที่ พวกเขาแค่เปลี่ยนกลยุทธ์ เพื่อครองความเชื่อมั่นใหม่ ในชื่อ “โปรตีน” #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-05-11 05:52:56Past 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 @jasonbohio 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.
To learn more about the project, you can visit: Designathon website: https://event.bitcoin.design/#project-recj4SVNLLkuWHpKq Discord channel: https://discord.com/channels/903125802726596648/1369200271632236574 Previous SN posts: https://stacker.news/items/974489/r/DeSign_r and https://stacker.news/items/974488/r/DeSign_r

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.

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! 😊

2025-05-12 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 05:45:52Finale: once the industry-standard of music notation software, now a cautionary tale. 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.

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.

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.

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.

2025-05-11 14:57:43Zeitgeber (ออกเสียงว่า ไซท’เกเบอะ) มาจากภาษาเยอรมัน คำว่า Zeit แปลว่า “เวลา” คำว่า Geber แปลว่า “ผู้ให้” หรือ “ตัวให้” แปลรวมกันว่า “ผู้ให้เวลา” หรือ “ตัวตั้งเวลา” ในบริบทชีววิทยาหมายถึง สิ่งแวดล้อมภายนอก ที่คอย “ตั้งนาฬิกาชีวภาพ” ภายในร่างกายเราให้เดินตามจังหวะที่เหมาะสม
นักวิจัยด้านนาฬิกาชีวภาพอย่าง Jürgen Aschoff และ Franz Halberg ในปี 1960–70s ใช้คำนี้เพื่ออธิบาย สิ่งเร้าที่ช่วยรีเซ็ตนาฬิกากลาง (Suprachiasmatic Nucleus) ของเราให้ตรงกับโลกภายนอก
ตัวอย่าง Zeitgeber หลักๆเช่น 1.แสงสว่าง-ความมืด แสงแดดเช้า (Blue light) บอกสมองว่า “เช้าแล้ว ตื่นได้” ตัวตั้ง circadian ความมืดตอนกลางคืน ปล่อยให้เมลาโทนินหลั่ง ส่งสัญญาณง่วงและพักผ่อน
2.อุณหภูมิ อุณหภูมิรอบตัวที่ลดลงตอนค่ำ ช่วยกระตุ้นการหลั่งเมลาโทนิน อีกแรงให้รู้ว่า “ได้เวลาเข้านอนแล้ว”
3.มื้ออาหาร เวลากินอาหารเป็นเวลาช่วยรีเซ็ตนาฬิกา peripheral clocks ในอวัยวะอย่างตับ ลำไส้
4.กิจกรรมทางสังคม-เสียง การทำงาน-พักผ่อนตามตารางประจำวัน หรือเสียงนาฬิกาปลุก / เสียงธรรมชาติช่วงเช้า ช่วยให้สมองปรับจังหวะได้
แล้วทำไม Zeitgeber ถึงมีความสำคัญขนาดนั้น? ลองนึกถึงนาฬิกาที่ตั้งผิดเวลาครับ ถ้าไม่มี zeitgeber ร่างกายเราจะเดินนาฬิกาชีวภาพได้ไม่ตรง “อาจง่วงไม่เป็นเวลา นอนไม่ลึก หรือฮอร์โมนเพี้ยน” การใช้ zeitgeber ให้เหมาะสม (เช่น รับแสงเช้าจริง ๆ งดจ้องจอหลังกลางคืน) จะช่วยให้ circadian, ultradian และ infradian rhythms ทำงานสอดคล้องกับธรรมชาติ ลดอาการ jet-lag, นอนไม่หลับ, อารมณ์ขึ้นลง หรือแม้แต่ปรับฮอร์โมนให้สมดุล ดังนั้น Zeitgeber คือ “เครื่องตั้งเวลา” ของร่างกายเรา ที่ช่วยให้ทุกกระบวนการชีวภาพเดินจังหวะตามโลกภายนอกอย่างกลมกลืน การเข้าใจและใช้ zeitgeber ให้ถูกต้อง จึงเป็นกุญแจสำคัญของสุขภาพกาย/ใจที่แข็งแรงยืนยาว
แสงแดดคือ zeitgeber สำคัญที่สุดของมนุษย์ ที่ไม่ได้มีบทบาทแค่กับวงจรรายวัน (circadian) แต่ยัง “ตั้งเวลา” ให้กับวงจรรายสั้น (ultradian) และวงจรรายยาว (infradian) ด้วย มาดูกันว่าแดดเข้ามาปั่นจังหวะเหล่านี้อย่างไรบ้าง

แสงแดดกับ Circadian Rhythm Circadian Rhythm คือวงจรชีวภาพรอบ 24 ชั่วโมง ควบคุมการนอน–ตื่น การหลั่งฮอร์โมน และอุณหภูมิร่างกาย แสงแดดเช้า (blue light) สายตาจะจับแสงผ่านจอประสาทตา (retina) ซึ่งมีเซลล์รับแสงชนิดพิเศษ (ipRGCs) ที่ไม่ใช่แค่ช่วยให้เรามองเห็น แต่ตอบสนองต่อความเข้มของแสงด้วย ด้วยการหยุดหลั่งเมลาโทนิน และเพิ่มคอร์ติซอล ทำให้ร่างกาย “ตื่น” และรีเซ็ตนาฬิกาทุกวัน กระบวนการนี้เรียกว่า photoentrainment ซึ่งทำให้ circadian rhythm ไม่ลอย (drift) ออกจากรอบ 24 ชม.
-
แสงแดดกับ Ultradian Rhythm Ultradian Rhythm คือวงจรชีวภาพที่สั้นกว่า 24 ชม. (เช่น การนอนสลับ NREM–REM ทุก ~90–120 นาที, การหลั่งฮอร์โมนเป็นช่วงเวลา) แสงแดด เช้า ช่วยเริ่มการหลั่งของคอร์ติซอล และกระตุ้นสมาธิ attention cycle (โพกัส 90 นาที พัก 15–20 นาที) ทำให้ ultradian cycles เหล่านี้เดินจังหวะตามความสดชื่นของแสง หรือแม้แต่ การรับแดดอ่อนๆ ช่วงเบรก (10–15 นาที) จะช่วยรีเซ็ต ultradian attention และ nap cycles ให้รอบต่อไปสดใส ไม่ง่วงเหงาหาวนอนกลางวัน
-
แสงแดดกับ Infradian Rhythm Infradian Rhythm คือวงจรชีวภาพยาวกว่า 24 ชม. (เช่น รอบเดือนของผู้หญิง) ดูกาลและแสงวันยาว–สั้น มีอิทธิพลต่ออารมณ์และฮอร์โมนรายปี (SAD) ร่างกายขาดแสง ทำให้ Melatonin ค้างในวัน ส่งผลให้อารมณ์ตกดิ่ง, รอบเดือน แสง UVB จะช่วยสังเคราะห์วิตามิน D ให้ปรับเอสโตรเจน/โปรเจสเตอโรนให้ขึ้น–ลงเป็นวัฏจักรที่สม่ำเสมอ รอบเดือนมาแบบมีคุณภาพ, ระบบภูมิคุ้มกัน แสง UVA สร้าง photolysis ของ nitrite สารพิเศษของโลก ปล่อย nitric oxide (NO) ช่วยในการลดอักเสบเรื้อรัง
เราจะเลือกใช้ “แดด” เป็น zeitgeber อย่างไรให้ตรงจังหวะ ให้ลองมองแต่ละช่วงเวลาแบบนี้ครับ พยายามทำให้เป็นจังหวะธรรมชาติของตัวเรา ไม่ต้องไปเกร็งเวลามากนะครับ - เช้า (6:30–9:00 น.) เปิดม่านหรือเดินรับแดด 10–15 นาที เน้น blue/UV light กระตุ้น circadian & ultradian - เบรกกลางวัน เดินออกไปรับแดดอ่อนๆ 10 นาที ช่วย ultradian attention & nap cycles - บ่ายแก่ (15:30–17:00 น.) ยืนรับแดดอ่อน–แสงอินฟราเรด ช่วย photobiomodulation ซ่อมแซมเซลล์ & สนับสนุน infradian recovery - หลีกเลี่ยงจอหลัง 20:00 น. ลดแสงสีฟ้าเทียม ให้เมลาโทนินผลิตตามธรรมชาติ
การใช้ แสงแดด ให้เป็น zeitgeber ครบทั้ง Circadian, Ultradian, Infradian จะทำให้ร่างกายเราเดินจังหวะกับธรรมชาติอย่างกลมกลืน ส่งผลต่อคุณภาพการนอน สมาธิ อารมณ์ และฮอร์โมนในทุกช่วงเวลาของชีวิตครับ

Rockstar released the second trailer for Grand Theft Auto VI, where they mention that it showcases both cinematic and gameplay scenes equally, though of course it doesn't show any direct gameplay.
This trailer also announces the release date for the game. The game will come out on the 26th of May, 2026, for the PS5 and the Xbox One.

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!

2025-04-15 11:03:15Prelude
I wrote this post differently than any of my others. It started with a discussion with AI on an OPSec-inspired review of separation of powers, and evolved into quite an exciting debate! I asked Grok to write up a summary in my overall writing style, which it got pretty well. I've decided to post it exactly as-is. Ultimately, I think there are two solid ideas driving my stance here:
- Perfect is the enemy of the good
- Failure is the crucible of success
Beyond that, just some hard-core belief in freedom, separation of powers, and operating from self-interest.
Intro
Alright, buckle up. I’ve been chewing on this idea for a while, and it’s time to spit it out. Let’s look at the U.S. government like I’d look at a codebase under a cybersecurity audit—OPSEC style, no fluff. Forget the endless debates about what politicians should do. That’s noise. I want to talk about what they can do, the raw powers baked into the system, and why we should stop pretending those powers are sacred. If there’s a hole, either patch it or exploit it. No half-measures. And yeah, I’m okay if the whole thing crashes a bit—failure’s a feature, not a bug.
The Filibuster: A Security Rule with No Teeth
You ever see a firewall rule that’s more theater than protection? That’s the Senate filibuster. Everyone acts like it’s this untouchable guardian of democracy, but here’s the deal: a simple majority can torch it any day. It’s not a law; it’s a Senate preference, like choosing tabs over spaces. When people call killing it the “nuclear option,” I roll my eyes. Nuclear? It’s a button labeled “press me.” If a party wants it gone, they’ll do it. So why the dance?
I say stop playing games. Get rid of the filibuster. If you’re one of those folks who thinks it’s the only thing saving us from tyranny, fine—push for a constitutional amendment to lock it in. That’s a real patch, not a Post-it note. Until then, it’s just a vulnerability begging to be exploited. Every time a party threatens to nuke it, they’re admitting it’s not essential. So let’s stop pretending and move on.
Supreme Court Packing: Because Nine’s Just a Number
Here’s another fun one: the Supreme Court. Nine justices, right? Sounds official. Except it’s not. The Constitution doesn’t say nine—it’s silent on the number. Congress could pass a law tomorrow to make it 15, 20, or 42 (hitchhiker’s reference, anyone?). Packing the court is always on the table, and both sides know it. It’s like a root exploit just sitting there, waiting for someone to log in.
So why not call the bluff? If you’re in power—say, Trump’s back in the game—say, “I’m packing the court unless we amend the Constitution to fix it at nine.” Force the issue. No more shadowboxing. And honestly? The court’s got way too much power anyway. It’s not supposed to be a super-legislature, but here we are, with justices’ ideologies driving the bus. That’s a bug, not a feature. If the court weren’t such a kingmaker, packing it wouldn’t even matter. Maybe we should be talking about clipping its wings instead of just its size.
The Executive Should Go Full Klingon
Let’s talk presidents. I’m not saying they should wear Klingon armor and start shouting “Qapla’!”—though, let’s be real, that’d be awesome. I’m saying the executive should use every scrap of power the Constitution hands them. Enforce the laws you agree with, sideline the ones you don’t. If Congress doesn’t like it, they’ve got tools: pass new laws, override vetoes, or—here’s the big one—cut the budget. That’s not chaos; that’s the system working as designed.
Right now, the real problem isn’t the president overreaching; it’s the bureaucracy. It’s like a daemon running in the background, eating CPU and ignoring the user. The president’s supposed to be the one steering, but the administrative state’s got its own agenda. Let the executive flex, push the limits, and force Congress to check it. Norms? Pfft. The Constitution’s the spec sheet—stick to it.
Let the System Crash
Here’s where I get a little spicy: I’m totally fine if the government grinds to a halt. Deadlock isn’t a disaster; it’s a feature. If the branches can’t agree, let the president veto, let Congress starve the budget, let enforcement stall. Don’t tell me about “essential services.” Nothing’s so critical it can’t take a breather. Shutdowns force everyone to the table—debate, compromise, or expose who’s dropping the ball. If the public loses trust? Good. They’ll vote out the clowns or live with the circus they elected.
Think of it like a server crash. Sometimes you need a hard reboot to clear the cruft. If voters keep picking the same bad admins, well, the country gets what it deserves. Failure’s the best teacher—way better than limping along on autopilot.
States Are the Real MVPs
If the feds fumble, states step up. Right now, states act like junior devs waiting for the lead engineer to sign off. Why? Federal money. It’s a leash, and it’s tight. Cut that cash, and states will remember they’re autonomous. Some will shine, others will tank—looking at you, California. And I’m okay with that. Let people flee to better-run states. No bailouts, no excuses. States are like competing startups: the good ones thrive, the bad ones pivot or die.
Could it get uneven? Sure. Some states might turn into sci-fi utopias while others look like a post-apocalyptic vidya game. That’s the point—competition sorts it out. Citizens can move, markets adjust, and failure’s a signal to fix your act.
Chaos Isn’t the Enemy
Yeah, this sounds messy. States ignoring federal law, external threats poking at our seams, maybe even a constitutional crisis. I’m not scared. The Supreme Court’s there to referee interstate fights, and Congress sets the rules for state-to-state play. But if it all falls apart? Still cool. States can sort it without a babysitter—it’ll be ugly, but freedom’s worth it. External enemies? They’ll either unify us or break us. If we can’t rally, we don’t deserve the win.
Centralizing power to avoid this is like rewriting your app in a single thread to prevent race conditions—sure, it’s simpler, but you’re begging for a deadlock. Decentralized chaos lets states experiment, lets people escape, lets markets breathe. States competing to cut regulations to attract businesses? That’s a race to the bottom for red tape, but a race to the top for innovation—workers might gripe, but they’ll push back, and the tension’s healthy. Bring it—let the cage match play out. The Constitution’s checks are enough if we stop coddling the system.
Why This Matters
I’m not pitching a utopia. I’m pitching a stress test. The U.S. isn’t a fragile porcelain doll; it’s a rugged piece of hardware built to take some hits. Let it fail a little—filibuster, court, feds, whatever. Patch the holes with amendments if you want, or lean into the grind. Either way, stop fearing the crash. It’s how we debug the republic.
So, what’s your take? Ready to let the system rumble, or got a better way to secure the code? Hit me up—I’m all ears.

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.

2025-05-10 08:11:36North American nations have been at the forefront of Bitcoin adoption; however, Nigeria, Kenya and South Africa have recently emerged as leaders in Africa.
There’s an increasing acceptance of Bitcoin on the African continent. More businesses, individuals and even financial organizations are using cryptocurrency to transact as an alternative to traditional banking systems. With the economies of the continent experiencing a lot of currency instability, poor banking infrastructure and exorbitantly priced remittances, Bitcoin is coming up as a viable solution financially. Analyzing Bitcoin price trends is crucial for investors, traders and businesses in Africa who want to implement digital assets in their operations.
The Impact of Bitcoin on the African Economy
North American nations have been at the forefront of Bitcoin adoption; however, Nigeria, Kenya and South Africa have recently emerged as leaders in Africa. Peer-to-peer cryptocurrency trading across the continent reached over $100 billion in 2023, making Africa one of the fastest-growing markets for blockchain technology, according to a report by Chainalysis. Several factors that fuel this growth include:
⚪ Less Dependable Fiat Currency : Zimbabwe and Nigeria have poor liquidity currencies, which makes it prudent for citizens to invest in Bitcoin to minimize losses due to devaluation over time.
⚪ Payments for Foreign Worker Remittances: Bitcoin is useful for relocating payments since it eliminates the need for using bitcoin remittance centers that charge ridiculous fees for payment processing.
⚪ Financial Inclusion : A large portion of the African population does not use banks. This makes bitcoin an ideal alternative, as it offers a decentralized and unbanked-friendly option for conducting transactions.
How Bitcoin’s Price Trends Affect the African Market
Businesses and individuals’ activities with bitcoin are directly proportional to its price trends and different nations have different ways through which they analyze this. Take Nigeria, for instance, where the e-commerce platform Patricia and several local sellers on Jumia have had to change their prices multiple times a day to keep in line with the fluctuating value of bitcoin. This has led to the platform’s volatility driving the pricing strategy of freelancers and remote workers who are paid in bitcoin and the currency has to be converted before being spent. As investor sentiment increases, so too does Bitcoin’s value, reaching 71,333 dollars in April of 2024, according to estimates from CoinMarketCap. The volatility, however, remains high and so there is a lot of uncertainty for African investors and businesses hoping to capitalize on the price movement.
Amongst the factors that impact the price movement of bitcoin, these are the most significant:
⚪ Global Adoption and Institutional Investments: An increase in spending by corporations leads to a higher demand and price for bitcoin.
⚪ Regulatory Changes : The law about cryptocurrency in different African countries is a vital influencer of regard and value for bitcoin.
⚪ Market Speculation and Trading Activity: The volatility of Bitcoin's price remains dependent on investor sentiment, especially in the emerging markets.
African Governments and Cryptocurrency Regulation
The policies for regulating Bitcoin are different in various countries in Africa. While countries like South Africa and Kenya are skeptical but working towards adjusting their policies to incorporate cryptocurrency into their economies, other nations remain hesitant. The following is a summary of the most important changes:
⚪ South Africa: The Financial Sector Conduct Authority (FSCA) offered more structured regulations by classifying crypto assets as financial products. This is a notable development towards more stringent regulations.
⚪ Nigeria: The Central Bank of Nigeria has previously restricted banks from supporting the facilitation of crypto transactions but is in the process of allowing it due to newly offered licenses to cryptocurrency exchanges, which under certain guidelines allow them to conduct regulated crypto activities.
⚪ Kenya: The Capital Markets Authority is seeking ways to regulate the security features of Bitcoin to enable it to reduce fraud. Bitcoin’s Impact on E-commerce and Small Businesses in Africa
With the rise of cryptocurrency acceptance, small-scale businesses and e-commerce businesses are increasing the option of paying for goods and services in Bitcoin. Businesses can reduce costs by:
⚪ Decreased Transaction Fees: Payments made using Bitcoin are usually cheaper than those made through credit cards. For example, some merchants in Ghana are beginning to use Bitcoin to bypass high fee payment processing, increase their profit margins and improve overall business profitability.
⚪ Reduced Transaction Delays: Banking transactions processed through the blockchain do away with delays associated with traditional banking.
⚪ Access to Global Markets: Businesses in Africa have no issues engaging with foreign clients because there is no currency conversion needed.
For instance, Yellow Card is a cryptocurrency exchange that operates in several countries in Africa and allows the trading of Bitcoins. In 2024, Yellow Card received more compliance approvals, which allowed the business to serve more than 20 countries in Africa. It now stands as a central player in the regional ecosystem of crypto. The platform allows businesses or individuals to transact efficiently with Bitcoin.
Challenges and Risks of Bitcoin Adoption in Africa
Unlike the advantages, there are several challenges regarding the adoption of Bitcoin in Africa:
⚪ Regulatory Uncertainty: The considerable flux of policies is difficult for businesses and investors to navigate, although some countries are beginning to put clearer policies into place, such as South Africa and Nigeria. As an example, Nigeria has plans to regulate the exchange of digital assets and put some control over it through the issuing of licenses for crypto exchanges, which are expected to be released in 2024.
⚪ Price Volatility: Changes in the price of Bitcoin can affect savings and transactions for businesses.
⚪ Limited Infrastructure: Internet and computer skills are primary requirements for greater acceptance.
Conclusion
Bitcoin is increasingly becoming a key component of Africa’s financial ecosystem by providing banking services or alternatives, facilitating financial remittances and supporting inclusion. Experts expect that Africa will increasingly adopt Bitcoin as a major tool of payment and remittance service across borders and for digital financial transactions. This will be the case if the regulations supporting its growth are put in place. While price volatility and regulatory challenges persist, knowing how prices behave and the developments within the Bitcoin ecosystem will help investors and businesses understand the new economy Africa is adopting. Africa indeed has the chance to use strategic adoption of technology to improve economic development and innovation through Bitcoin if action is taken.

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?

Para distribuir os dados, metadados e dados do sistema em todos os dispositivos de armazenamento do RAID (incluindo o dispositivo de armazenamento recém-adicionado) montados no diretório /data , execute o seguinte comando:
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 .

2025-04-09 21:19:39DAOs promised decentralization. They offered a system where every member could influence a project's direction, where money and power were transparently distributed, and decisions were made through voting. All of it recorded immutably on the blockchain, free from middlemen.
But something didn’t work out. In practice, most DAOs haven’t evolved into living, self-organizing organisms. They became something else: clubs where participation is unevenly distributed. Leaders remained - only now without formal titles. They hold influence through control over communications, task framing, and community dynamics. Centralization still exists, just wrapped in a new package.
But there's a second, less obvious problem. Crowds can’t create strategy. In DAOs, people vote for what "feels right to the majority." But strategy isn’t about what feels good - it’s about what’s necessary. Difficult, unpopular, yet forward-looking decisions often fail when put to a vote. A founder’s vision is a risk. But in healthy teams, it’s that risk that drives progress. In DAOs, risk is almost always diluted until it becomes something safe and vague.
Instead of empowering leaders, DAOs often neutralize them. This is why many DAOs resemble consensus machines. Everyone talks, debates, and participates, but very little actually gets done. One person says, “Let’s jump,” and five others respond, “Let’s discuss that first.” This dynamic might work for open forums, but not for action.
Decentralization works when there’s trust and delegation, not just voting. Until DAOs develop effective systems for assigning roles, taking ownership, and acting with flexibility, they will keep losing ground to old-fashioned startups led by charismatic founders with a clear vision.
We’ve seen this in many real-world cases. Take MakerDAO, one of the most mature and technically sophisticated DAOs. Its governance token (MKR) holders vote on everything from interest rates to protocol upgrades. While this has allowed for transparency and community involvement, the process is often slow and bureaucratic. Complex proposals stall. Strategic pivots become hard to implement. And in 2023, a controversial proposal to allocate billions to real-world assets passed only narrowly, after months of infighting - highlighting how vision and execution can get stuck in the mud of distributed governance.
On the other hand, Uniswap DAO, responsible for the largest decentralized exchange, raised governance participation only after launching a delegation system where token holders could choose trusted representatives. Still, much of the activity is limited to a small group of active contributors. The vast majority of token holders remain passive. This raises the question: is it really community-led, or just a formalized power structure with lower transparency?
Then there’s ConstitutionDAO, an experiment that went viral. It raised over $40 million in days to try and buy a copy of the U.S. Constitution. But despite the hype, the DAO failed to win the auction. Afterwards, it struggled with refund logistics, communication breakdowns, and confusion over governance. It was a perfect example of collective enthusiasm without infrastructure or planning - proof that a DAO can raise capital fast but still lack cohesion.
Not all efforts have failed. Projects like Gitcoin DAO have made progress by incentivizing small, individual contributions. Their quadratic funding mechanism rewards projects based on the number of contributors, not just the size of donations, helping to elevate grassroots initiatives. But even here, long-term strategy often falls back on a core group of organizers rather than broad community consensus.
The pattern is clear: when the stakes are low or the tasks are modular, DAOs can coordinate well. But when bold moves are needed—when someone has to take responsibility and act under uncertainty DAOs often freeze. In the name of consensus, they lose momentum.
That’s why the organization of the future can’t rely purely on decentralization. It must encourage individual initiative and the ability to take calculated risks. People need to see their contribution not just as a vote, but as a role with clear actions and expected outcomes. When the situation demands, they should be empowered to act first and present the results to the community afterwards allowing for both autonomy and accountability. That’s not a flaw in the system. It’s how real progress happens.

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.

2025-05-11 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.

2025-05-06 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! 🌸

2025-05-11 21:32:19Bitkoin, kao jedinstvena digitalna valuta, postaje poznat široj javnosti u trenutku kada se pojavljuju prvi znaci svetske ekonomske krize a postojeći finansijski sistem počinje da pokazuje sve svoje slabosti. Danas, bitkoin, izaziva veliku pažnju svojim naglim skokovima i padovima.
Osnovna ideja o o decentralizovanim valutama potekla je od osnivača kripto-pank pokreta, među kojima su bili direktori kompanija naprednih tehnologija, univerzitetski profesori i istraživači iz oblasti matematike i fizike. Njihova ideja zasnovana je na anonimnoj, istovremenoj komunikaciji koja neće biti kontrolisana i nadgledana od neke treće strane u procesu.
Šta je kriptovaluta, ko je njen tvorac, kako do nje doći, kako trgovati i gde je čuvati, neka su od pitanja za čijim odgovorima tragamo u emisiji.
Sagovornici u emisiji su svi oni koji su u poslednjih godinu dana bili relevantni učesnici priča o kriptovaluti u Srbiji: osnivači Asocijacije bitkoin, predstavnici Narodne banke Srbije i predstavnici medija.

2025-04-05 16:58:58I’m drawn to extremities in art. The louder, the bolder, the more outrageous, the better. Bold art takes me out of the mundane into a whole new world where anything and everything is possible. Having grown up in the safety of the suburban midwest, I was a bit of a rebellious soul in search of the satiation that only came from the consumption of the outrageous. My inclination to find bold art draws me to NOSTR, because I believe NOSTR can be the place where the next generation of artistic pioneers go to express themselves. I also believe that as much as we are able, were should invite them to come create here.
My Background: A Small Side Story
My father was a professional gamer in the 80s, back when there was no money or glory in the avocation. He did get a bit of spotlight though after the fact: in the mid 2000’s there were a few parties making documentaries about that era of gaming as well as current arcade events (namely 2007’sChasing GhostsandThe King of Kong: A Fistful of Quarters). As a result of these documentaries, there was a revival in the arcade gaming scene. My family attended events related to the documentaries or arcade gaming and I became exposed to a lot of things I wouldn’t have been able to find. The producer ofThe King of Kong: A Fistful of Quarters had previously made a documentary calledNew York Dollwhich was centered around the life of bassist Arthur Kane. My 12 year old mind was blown: The New York Dolls were a glam-punk sensation dressed in drag. The music was from another planet. Johnny Thunders’ guitar playing was like Chuck Berry with more distortion and less filter. Later on I got to meet the Galaga record holder at the time, Phil Day, in Ottumwa Iowa. Phil is an Australian man of high intellect and good taste. He exposed me to great creators such as Nick Cave & The Bad Seeds, Shakespeare, Lou Reed, artists who created things that I had previously found inconceivable.
I believe this time period informed my current tastes and interests, but regrettably I think it also put coals on the fire of rebellion within. I stopped taking my parents and siblings seriously, the Christian faith of my family (which I now hold dearly to) seemed like a mundane sham, and I felt I couldn’t fit in with most people because of my avant-garde tastes. So I write this with the caveat that there should be a way to encourage these tastes in children without letting them walk down the wrong path. There is nothing inherently wrong with bold art, but I’d advise parents to carefully find ways to cultivate their children’s tastes without completely shutting them down and pushing them away as a result. My parents were very loving and patient during this time; I thank God for that.
With that out of the way, lets dive in to some bold artists:
Nicolas Cage: Actor
There is an excellent video by Wisecrack on Nicolas Cage that explains him better than I will, which I will linkhere. Nicolas Cage rejects the idea that good acting is tied to mere realism; all of his larger than life acting decisions are deliberate choices. When that clicked for me, I immediately realized the man is a genius. He borrows from Kabuki and German Expressionism, art forms that rely on exaggeration to get the message across. He has even created his own acting style, which he calls Nouveau Shamanic. He augments his imagination to go from acting to being. Rather than using the old hat of method acting, he transports himself to a new world mentally. The projects he chooses to partake in are based on his own interests or what he considers would be a challenge (making a bad script good for example). Thus it doesn’t matter how the end result comes out; he has already achieved his goal as an artist. Because of this and because certain directors don’t know how to use his talents, he has a noticeable amount of duds in his filmography. Dig around the duds, you’ll find some pure gold. I’d personally recommend the filmsPig, Joe, Renfield, and his Christmas film The Family Man.
Nick Cave: Songwriter
What a wild career this man has had! From the apocalyptic mayhem of his band The Birthday Party to the pensive atmosphere of his albumGhosteen, it seems like Nick Cave has tried everything. I think his secret sauce is that he’s always working. He maintains an excellent newsletter calledThe Red Hand Files, he has written screenplays such asLawless, he has written books, he has made great film scores such asThe Assassination of Jesse James by the Coward Robert Ford, the man is religiously prolific. I believe that one of the reasons he is prolific is that he’s not afraid to experiment. If he has an idea, he follows it through to completion. From the albumMurder Ballads(which is comprised of what the title suggests) to his rejected sequel toGladiator(Gladiator: Christ Killer), he doesn’t seem to be afraid to take anything on. This has led to some over the top works as well as some deeply personal works. Albums likeSkeleton TreeandGhosteenwere journeys through the grief of his son’s death. The Boatman’s Callis arguably a better break-up album than anything Taylor Swift has put out. He’s not afraid to be outrageous, he’s not afraid to offend, but most importantly he’s not afraid to be himself. Works I’d recommend include The Birthday Party’sLive 1981-82, Nick Cave & The Bad Seeds’The Boatman’s Call, and the filmLawless.
Jim Jarmusch: Director
I consider Jim’s films to be bold almost in an ironic sense: his works are bold in that they are, for the most part, anti-sensational. He has a rule that if his screenplays are criticized for a lack of action, he makes them even less eventful. Even with sensational settings his films feel very close to reality, and they demonstrate the beauty of everyday life. That's what is bold about his art to me: making the sensational grounded in reality while making everyday reality all the more special. Ghost Dog: The Way of the Samurai is about a modern-day African-American hitman who strictly follows the rules of the ancient Samurai, yet one can resonate with the humanity of a seemingly absurd character. Only Lovers Left Aliveis a vampire love story, but in the middle of a vampire romance one can see their their own relationships in a new deeply human light. Jim’s work reminds me that art reflects life, and that there is sacred beauty in seemingly mundane everyday life. I personally recommend his filmsPaterson,Down by Law, andCoffee and Cigarettes.
NOSTR: We Need Bold Art
NOSTR is in my opinion a path to a better future. In a world creeping slowly towards everything apps, I hope that the protocol where the individual owns their data wins over everything else. I love freedom and sovereignty. If NOSTR is going to win the race of everything apps, we need more than Bitcoin content. We need more than shirtless bros paying for bananas in foreign countries and exercising with girls who have seductive accents. Common people cannot see themselves in such a world. NOSTR needs to catch the attention of everyday people. I don’t believe that this can be accomplished merely by introducing more broadly relevant content; people are searching for content that speaks to them. I believe that NOSTR can and should attract artists of all kinds because NOSTR is one of the few places on the internet where artists can express themselves fearlessly. Getting zaps from NOSTR’s value-for-value ecosystem has far less friction than crowdfunding a creative project or pitching investors that will irreversibly modify an artist’s vision. Having a place where one can post their works without fear of censorship should be extremely enticing. Having a place where one can connect with fellow humans directly as opposed to a sea of bots should seem like the obvious solution. If NOSTR can become a safe haven for artists to express themselves and spread their work, I believe that everyday people will follow. The banker whose stressful job weighs on them will suddenly find joy with an original meme made by a great visual comedian. The programmer for a healthcare company who is drowning in hopeless mundanity could suddenly find a new lust for life by hearing the song of a musician who isn’t afraid to crowdfund their their next project by putting their lighting address on the streets of the internet. The excel guru who loves independent film may find that NOSTR is the best way to support non corporate movies. My closing statement: continue to encourage the artists in your life as I’m sure you have been, but while you’re at it give them the purple pill. You may very well be a part of building a better future.

2025-05-05 05:15:02Crabtree's Framework for Evaluating Human-Centered Research
Picture this: You've spent three weeks conducting qualitative research for a finance app redesign. You carefully recruited 12 participants, conducted in-depth interviews, and identified patterns around financial anxiety and decision paralysis. You're excited to present your findings when the inevitable happens:
"But are these results statistically significant?"
"Just 12 people? How can we make decisions that affect thousands of users based on conversations with just 12 people?"
As UX professionals, we regularly face stakeholders who evaluate our qualitative research using criteria designed for quantitative methods... This misalignment undermines the unique value qualitative research brings to product development.

2025-05-09 17:21:32Freedom—a word that resonates deeply within the hearts of many. It is a concept that transcends cultures, boundaries, and time itself. From the pages of history to the hopes of future generations, the quest for freedom has always been at the core of human existence.
What Is Freedom?
At its simplest, freedom is the power or right to act, speak, or think as one wants without hindrance or restraint. But in reality, it is far more nuanced. Freedom is not just about the absence of oppression; it is about the presence of opportunity—the chance to pursue one's dreams, express thoughts without fear, and live in harmony with one’s beliefs.
The Many Faces of Freedom
-
Political Freedom: The right to participate in governance, to vote, and to have a voice in decision-making.
-
Economic Freedom: The ability to work, own property, and engage in business without unreasonable restrictions.
-
Social Freedom: The acceptance of diversity and the ability to live without discrimination.
-
Personal Freedom: The right to privacy, personal choices, and the liberty to define one's own path.
Why Freedom Matters
Freedom matters because it is the foundation of innovation and progress. Societies that encourage freedom allow their people to think differently, to challenge the status quo, and to bring about change. Without freedom, creativity is stifled, voices are silenced, and growth becomes stagnant.
Protecting and Valuing Freedom
Freedom is fragile. It must be protected with vigilance and cherished with gratitude. History is filled with examples where freedom was hard-won and even harder to maintain. Today, as we navigate an interconnected world, the call to safeguard freedom is as loud as ever.
A Call to Action
Cherish your freedoms, no matter how small they may seem. Speak up for those who cannot. Stand firm against injustice. Remember, freedom is not just a privilege; it is a responsibility.
“Freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed.” — Martin Luther King Jr.
Embrace it. Protect it. Share it.

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.

2025-05-09 15:46:24Since its TGE, AGT has moved beyond its early role as a governance token within AIVille’s farming economy. It’s now evolving into a foundational asset that connects humans and AI agents, in-game interactions and real-world use cases. This isn’t just the next phase of a game—it’s the beginning of a new era where intelligent agents and humans co-create a living digital society. Here’s how AGT is becoming the fuel behind that future.
- AI Characters as Personalized Companions The first example of this transformation is Selena, AIVille’s Telegram-native AI companion. You can chat with her now for free at @Tavern_Owner_Selena_Bot. Selena is powered by her own independent memory system, enabling personalized, emotionally responsive conversations that evolve over time. Beyond private chats, Selena also participates in public community groups—responding to questions, engaging with users, and providing companionship in group settings. She’s more than a chatbot—she’s a social presence in the AIVille ecosystem. While currently free to use, certain advanced features and extended interactions will soon require AGT, making Selena a live demonstration of AGT’s role in unlocking real AI experiences.
More characters are on the way: Owen, your AI tutor for learning AI tools, coding basics, or advanced Web3 mechanics. Lulu, your personalized news curator—think of her as your intelligent Substack. Mayor Logan, offering town updates, strategic insights, and even mock governance simulations. Arjay, the town’s resident DJ, creating mood-based playlists you can reserve with AGT. Lucas, a merchant bot offering market tips, negotiation roleplay, and trend forecasting.
Each character is built with private memory and a distinct personality. Interacting with them isn't just fun—it creates lasting, evolving relationships. AGT unlocks deeper access.
- AI Bots for Projects: The AIVille Co-Creation Program We’re launching the AI Co-Creation Program, designed for Web3 projects to easily spin up custom AI bots with memory and personality. These bots can support communities, onboard users, answer questions, or drive engagement—and they’re powered by AGT.
The setup is quick, the AGT required is minimal, and most importantly, participating projects become part of the AIVille ecosystem. AGT serves as the bridge—not just a fee, but a commitment to shared growth. We’re actively testing with partners now. If you’re building in Web3 and want to add a smart, persistent AI layer to your project, reach out. We’re also recruiting global ambassadors: connect a project and help them onboard, and you’ll earn AGT rewards. All AGT from these partnerships is injected into the AIVille DAO, where it will be allocated transparently for buybacks, ecosystem incentives, and long-term development.
- Governance, Reimagined: A Society of Humans and Agents AIVille is introducing a two-layer governance model—one for human players, and one for AI agents. Together, they’ll shape the rules of the world. Human Governance AGT holders will be able to: Propose and vote on decisions like tax rates, new zones, and fee structures Stake AGT to unlock governance perks and exclusive features Fund public goods with DAO-managed AGT reserves Participate in a transparent system where influence is earned, not assumed
AI Economic Alliance In parallel, key AI agents—like Logan, Lucas, and Arjay—will be able to propose changes, backed by AGT. Each proposal requires AGT to be burned as a bond
Passed proposals return a portion; failed ones are fully burned
Humans can vote to support or reject AI proposals, creating real-time, inter-agent governance dynamics
This is more than a voting system—it’s an experiment in social architecture between multiple intelligent actors. And AGT is the trust layer between them.
- What AGT Really Represents AGT isn’t just a token. It’s shared infrastructure. It’s programmable social capital. It’s the backbone of a digital civilization co-created by its users.
It’s how you teach an AI. How you shape the economy. How you reserve access, express values, and coordinate effort. This asset isn’t owned by a company or foundation—it’s governed, used, and grown by the people and agents who rely on it. Our roadmap includes expanding AI services, adding more governance mechanisms, and welcoming more ecosystems into the fold. Every new use case makes AGT more valuable, more usable, and more alive.
- To Our Community: Thank You AGT wouldn’t be here without the people behind it: The AMA hosts introducing AIVille to new audiences The meme creators, sticker designers, and shirt printers The Discord mods, Telegram helpers, and wiki writers
You made this real before the tech did. You gave it soul before it had memory. This isn’t our experiment. It’s yours. Let’s keep building—together.

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.

Quando o assunto é privacidade em celulares, uma das medidas comumente mencionadas é a remoção de bloatwares do dispositivo, também chamado de debloat. O meio mais eficiente para isso sem dúvidas é a troca de sistema operacional. Custom Rom’s como LineageOS, GrapheneOS, Iodé, CalyxOS, etc, já são bastante enxutos nesse quesito, principalmente quanto não é instalado os G-Apps com o sistema. No entanto, essa prática pode acabar resultando em problemas indesejados como a perca de funções do dispositivo, e até mesmo incompatibilidade com apps bancários, tornando este método mais atrativo para quem possui mais de um dispositivo e separando um apenas para privacidade. Pensando nisso, pessoas que possuem apenas um único dispositivo móvel, que são necessitadas desses apps ou funções, mas, ao mesmo tempo, tem essa visão em prol da privacidade, buscam por um meio-termo entre manter a Stock rom, e não ter seus dados coletados por esses bloatwares. Felizmente, a remoção de bloatwares é possível e pode ser realizada via root, ou mais da maneira que este artigo irá tratar, via adb.
O que são bloatwares?
Bloatware é a junção das palavras bloat (inchar) + software (programa), ou seja, um bloatware é basicamente um programa inútil ou facilmente substituível — colocado em seu dispositivo previamente pela fabricante e operadora — que está no seu dispositivo apenas ocupando espaço de armazenamento, consumindo memória RAM e pior, coletando seus dados e enviando para servidores externos, além de serem mais pontos de vulnerabilidades.
O que é o adb?
O Android Debug Brigde, ou apenas adb, é uma ferramenta que se utiliza das permissões de usuário shell e permite o envio de comandos vindo de um computador para um dispositivo Android exigindo apenas que a depuração USB esteja ativa, mas também pode ser usada diretamente no celular a partir do Android 11, com o uso do Termux e a depuração sem fio (ou depuração wifi). A ferramenta funciona normalmente em dispositivos sem root, e também funciona caso o celular esteja em Recovery Mode.
Requisitos:
Para computadores:
• Depuração USB ativa no celular; • Computador com adb; • Cabo USB;
Para celulares:
• Depuração sem fio (ou depuração wifi) ativa no celular; • Termux; • Android 11 ou superior;
Para ambos:
• Firewall NetGuard instalado e configurado no celular; • Lista de bloatwares para seu dispositivo;
Ativação de depuração:
Para ativar a Depuração USB em seu dispositivo, pesquise como ativar as opções de desenvolvedor de seu dispositivo, e lá ative a depuração. No caso da depuração sem fio, sua ativação irá ser necessária apenas no momento que for conectar o dispositivo ao Termux.
Instalação e configuração do NetGuard
O NetGuard pode ser instalado através da própria Google Play Store, mas de preferência instale pela F-Droid ou Github para evitar telemetria.
F-Droid: https://f-droid.org/packages/eu.faircode.netguard/
Github: https://github.com/M66B/NetGuard/releases
Após instalado, configure da seguinte maneira:
Configurações → padrões (lista branca/negra) → ative as 3 primeiras opções (bloquear wifi, bloquear dados móveis e aplicar regras ‘quando tela estiver ligada’);
Configurações → opções avançadas → ative as duas primeiras (administrar aplicativos do sistema e registrar acesso a internet);
Com isso, todos os apps estarão sendo bloqueados de acessar a internet, seja por wifi ou dados móveis, e na página principal do app basta permitir o acesso a rede para os apps que você vai usar (se necessário). Permita que o app rode em segundo plano sem restrição da otimização de bateria, assim quando o celular ligar, ele já estará ativo.
Lista de bloatwares
Nem todos os bloatwares são genéricos, haverá bloatwares diferentes conforme a marca, modelo, versão do Android, e até mesmo região.
Para obter uma lista de bloatwares de seu dispositivo, caso seu aparelho já possua um tempo de existência, você encontrará listas prontas facilmente apenas pesquisando por elas. Supondo que temos um Samsung Galaxy Note 10 Plus em mãos, basta pesquisar em seu motor de busca por:
Samsung Galaxy Note 10 Plus bloatware list
Provavelmente essas listas já terão inclusas todos os bloatwares das mais diversas regiões, lhe poupando o trabalho de buscar por alguma lista mais específica.
Caso seu aparelho seja muito recente, e/ou não encontre uma lista pronta de bloatwares, devo dizer que você acaba de pegar em merda, pois é chato para um caralho pesquisar por cada aplicação para saber sua função, se é essencial para o sistema ou se é facilmente substituível.
De antemão já aviso, que mais para frente, caso vossa gostosura remova um desses aplicativos que era essencial para o sistema sem saber, vai acabar resultando na perda de alguma função importante, ou pior, ao reiniciar o aparelho o sistema pode estar quebrado, lhe obrigando a seguir com uma formatação, e repetir todo o processo novamente.
Download do adb em computadores
Para usar a ferramenta do adb em computadores, basta baixar o pacote chamado SDK platform-tools, disponível através deste link: https://developer.android.com/tools/releases/platform-tools. Por ele, você consegue o download para Windows, Mac e Linux.
Uma vez baixado, basta extrair o arquivo zipado, contendo dentro dele uma pasta chamada platform-tools que basta ser aberta no terminal para se usar o adb.
Download do adb em celulares com Termux.
Para usar a ferramenta do adb diretamente no celular, antes temos que baixar o app Termux, que é um emulador de terminal linux, e já possui o adb em seu repositório. Você encontra o app na Google Play Store, mas novamente recomendo baixar pela F-Droid ou diretamente no Github do projeto.
F-Droid: https://f-droid.org/en/packages/com.termux/
Github: https://github.com/termux/termux-app/releases
Processo de debloat
Antes de iniciarmos, é importante deixar claro que não é para você sair removendo todos os bloatwares de cara sem mais nem menos, afinal alguns deles precisam antes ser substituídos, podem ser essenciais para você para alguma atividade ou função, ou até mesmo são insubstituíveis.
Alguns exemplos de bloatwares que a substituição é necessária antes da remoção, é o Launcher, afinal, é a interface gráfica do sistema, e o teclado, que sem ele só é possível digitar com teclado externo. O Launcher e teclado podem ser substituídos por quaisquer outros, minha recomendação pessoal é por aqueles que respeitam sua privacidade, como Pie Launcher e Simple Laucher, enquanto o teclado pelo OpenBoard e FlorisBoard, todos open-source e disponíveis da F-Droid.
Identifique entre a lista de bloatwares, quais você gosta, precisa ou prefere não substituir, de maneira alguma você é obrigado a remover todos os bloatwares possíveis, modifique seu sistema a seu bel-prazer. O NetGuard lista todos os apps do celular com o nome do pacote, com isso você pode filtrar bem qual deles não remover.
Um exemplo claro de bloatware insubstituível e, portanto, não pode ser removido, é o com.android.mtp, um protocolo onde sua função é auxiliar a comunicação do dispositivo com um computador via USB, mas por algum motivo, tem acesso a rede e se comunica frequentemente com servidores externos. Para esses casos, e melhor solução mesmo é bloquear o acesso a rede desses bloatwares com o NetGuard.
MTP tentando comunicação com servidores externos:
Executando o adb shell
No computador
Faça backup de todos os seus arquivos importantes para algum armazenamento externo, e formate seu celular com o hard reset. Após a formatação, e a ativação da depuração USB, conecte seu aparelho e o pc com o auxílio de um cabo USB. Muito provavelmente seu dispositivo irá apenas começar a carregar, por isso permita a transferência de dados, para que o computador consiga se comunicar normalmente com o celular.
Já no pc, abra a pasta platform-tools dentro do terminal, e execute o seguinte comando:
./adb start-server
O resultado deve ser:
daemon not running; starting now at tcp:5037 daemon started successfully
E caso não apareça nada, execute:
./adb kill-server
E inicie novamente.
Com o adb conectado ao celular, execute:
./adb shell
Para poder executar comandos diretamente para o dispositivo. No meu caso, meu celular é um Redmi Note 8 Pro, codinome Begonia.
Logo o resultado deve ser:
begonia:/ $
Caso ocorra algum erro do tipo:
adb: device unauthorized. This adb server’s $ADB_VENDOR_KEYS is not set Try ‘adb kill-server’ if that seems wrong. Otherwise check for a confirmation dialog on your device.
Verifique no celular se apareceu alguma confirmação para autorizar a depuração USB, caso sim, autorize e tente novamente. Caso não apareça nada, execute o kill-server e repita o processo.
No celular
Após realizar o mesmo processo de backup e hard reset citado anteriormente, instale o Termux e, com ele iniciado, execute o comando:
pkg install android-tools
Quando surgir a mensagem “Do you want to continue? [Y/n]”, basta dar enter novamente que já aceita e finaliza a instalação
Agora, vá até as opções de desenvolvedor, e ative a depuração sem fio. Dentro das opções da depuração sem fio, terá uma opção de emparelhamento do dispositivo com um código, que irá informar para você um código em emparelhamento, com um endereço IP e porta, que será usado para a conexão com o Termux.
Para facilitar o processo, recomendo que abra tanto as configurações quanto o Termux ao mesmo tempo, e divida a tela com os dois app’s, como da maneira a seguir:
Para parear o Termux com o dispositivo, não é necessário digitar o ip informado, basta trocar por “localhost”, já a porta e o código de emparelhamento, deve ser digitado exatamente como informado. Execute:
adb pair localhost:porta CódigoDeEmparelhamento
De acordo com a imagem mostrada anteriormente, o comando ficaria “adb pair localhost:41255 757495”.
Com o dispositivo emparelhado com o Termux, agora basta conectar para conseguir executar os comandos, para isso execute:
adb connect localhost:porta
Obs: a porta que você deve informar neste comando não é a mesma informada com o código de emparelhamento, e sim a informada na tela principal da depuração sem fio.
Pronto! Termux e adb conectado com sucesso ao dispositivo, agora basta executar normalmente o adb shell:
adb shell
Remoção na prática Com o adb shell executado, você está pronto para remover os bloatwares. No meu caso, irei mostrar apenas a remoção de um app (Google Maps), já que o comando é o mesmo para qualquer outro, mudando apenas o nome do pacote.
Dentro do NetGuard, verificando as informações do Google Maps:
Podemos ver que mesmo fora de uso, e com a localização do dispositivo desativado, o app está tentando loucamente se comunicar com servidores externos, e informar sabe-se lá que peste. Mas sem novidades até aqui, o mais importante é que podemos ver que o nome do pacote do Google Maps é com.google.android.apps.maps, e para o remover do celular, basta executar:
pm uninstall –user 0 com.google.android.apps.maps
E pronto, bloatware removido! Agora basta repetir o processo para o resto dos bloatwares, trocando apenas o nome do pacote.
Para acelerar o processo, você pode já criar uma lista do bloco de notas com os comandos, e quando colar no terminal, irá executar um atrás do outro.
Exemplo de lista:
Caso a donzela tenha removido alguma coisa sem querer, também é possível recuperar o pacote com o comando:
cmd package install-existing nome.do.pacote
Pós-debloat
Após limpar o máximo possível o seu sistema, reinicie o aparelho, caso entre no como recovery e não seja possível dar reboot, significa que você removeu algum app “essencial” para o sistema, e terá que formatar o aparelho e repetir toda a remoção novamente, desta vez removendo poucos bloatwares de uma vez, e reiniciando o aparelho até descobrir qual deles não pode ser removido. Sim, dá trabalho… quem mandou querer privacidade?
Caso o aparelho reinicie normalmente após a remoção, parabéns, agora basta usar seu celular como bem entender! Mantenha o NetGuard sempre executando e os bloatwares que não foram possíveis remover não irão se comunicar com servidores externos, passe a usar apps open source da F-Droid e instale outros apps através da Aurora Store ao invés da Google Play Store.

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!

2025-04-18 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!

2025-05-09 13:22:26It was a dark and stormy night. It had to be: Weather had been fired. If they were working for him he would have fired them, but that is just embarrassed arrogance talking. He remembers standing in the middle of his office, his trashed office. It looked like a hurricane had hit it, or vagrants had been living in it for years, nothing of value was left intact. Monitors were shattered on the floor, couches were covered in debris. There was evidence of food and magazine pages in every gaze space. His supervisor, his name escaped him, was grey with anger. “Explain this!” he had shouted with a tremble, but he couldn’t. Every time he tried to think of the events of the day he met a dazzling white blankness.
He was escorted, handcuffed, to a room by two security guards with his supervisor trailing them. Weather felt humiliated and frustrated, but he didn’t know why. He sat, shivering slightly, in a low-lit conference room he had never seen before. Actually, he doesn’t remember any windows or any specific light source, just a haze of shadows. The big boss is sitting opposite him, looking haggard and white as a sun-bleached shell. His supervisor was sitting on his right looking equally haggard and even depressed. They appeared genuine and he knew it was bad news for him.
“You’ve embarrassed this company! There is even a chance you have ruined us all and you have the audacity to sit there and pretend that you can’t remember a thing!”
He knew there was no point in arguing, he had no ideas with which to make up any argument. He sat staring into space.
“At least, give us a story. Tell us how bored you were and tried to create your own weather system by running around the room swinging the fan around like a sugar mad teenager!”
He couldn’t even clear his throat. He couldn’t lift his eyes to meet theirs. He knew his career was over and they were fearful all their ideals had crashed irreparably. He stared into space at the globe standing in the middle of the table. The more he stared at it the more he realized that it seemed to have an atmosphere around it. There were clouds covering patches of the earth. He didn’t dare bring their attention to it. The only memories he could dredge up seemed like dreams, and they’re hardly constitute a defence.
He looked up at their faces finally, surprised to see more alarm than anger, like they were actually afraid of him. They both stood up suddenly, wanting to get out the room as quickly as possible.
“You have brought Global Sky Incorporated into disrepute. You’ve embarrassed us. You have possibly ruined hundreds of careers here! We never want to see you again! You are never to come within a hundred metres of this building. You can never use your research ever again, it never happened. Everything you have ever written will be classified and restricted until you are dead!” The big boss was shaking wild, Weather was grateful for the security guards that hurled him out of his chair and marched him out of the building.
The afternoon sky had been a deathly grey. It had occurred to him but now he was a little shocked at how much control they had over the weather, maybe it was a good thing that he had been fired, but probably a bad thing as they would certainly make worse mistakes than him, whatever he might have done. He was confused, not sure if he been fired for trashing his office or for state of the weather. About the weird weather he has no idea, all he can remember is a dazzling blank whiteness, and that is hardly a memory.
He couldn’t face going directly home, jumped on public transport travelling on tracks laid down on old unused highways and headed for the city beach, or what passed for a beach. He sat on a concrete bench gazing across the grey sand at the shimmering waves. They weren’t shimmering because of the sparkling sunlight, but the contaminates in the water. But still it was tranquil enough. He tried to think about his day, but couldn’t get past the white blankness, everything else before that was like a postcard from someone else’s holiday, and they looked like movies he might have seen. He has a framed vision of himself in his office with office supplies flying around him without touching him. Clearly, as they weren’t touching him, it had nothing to do with his behaviour. He is a victim here. It wasn’t his fault, the world was changing and the powers that be wanted more control. It seems like Global Weather Incorporated (GWI) lost control of their equipment and need a fall guy, they didn’t need him anymore. Squeezed his brain for the algorithms, then threw him onto the streets. He was nothing without his research, it’s all he had done his entire life. He would have to pursue it, but that would as useful as talking to a brick wall, the world was less transparent; government, science and advertising companies had a law of their own and a police force to uphold them.
He believed in good and the unveiling of truth. He had a romantic connection to the idea that truth grew in people’s hearts that everyone wanted the best for everyone else, no matter what skin colour, car colour they had, or star sign they were born under. Everybody wanted peace, a roof over their heads and food in their bellies; and wanted these things for their neighbours too. If only his neighbours had the same beliefs.
It was late afternoon now. He could tell by the slight luminosity of the grey clouds near the horizon, close to a cloudless gap, a slit above the horizon through which the sun could bid its final farewell to the day. He was in no mood for a sunset minute. He picked his bum off the bench, dusted it off and began his journey home, not wanting to be left in the dark in the city, opportune prey for corrupt cops. Everyone was coming out of the offices, beginning the big commute home. Car pools had reshaped their cars to fit more people in, and many climbed on to the reinvented trams, sitting if they were lucky, holding onto ceiling straps if they were unlucky like him. Couples sat together staring into each other’s eyes, friends joked and discussed their office politics. He hated the commute back and forth from work, it made him feel alone, desperate and unwanted. There had been no office politics for him, it was just him and his mostly silent supervisor.
The sky was struck red, a wound inflicted on the sky, it bleed for a minute then all went dark. Reality shuddered as it returned to him, this would be his last commute along this route. He was without a job; his recently regained self-esteem was destroyed. At the end of university he had wondered if he had a career anywhere, if his self-inflicted social isolation had been worth it and GWI had lifted him out of academic gutter and placed him on a pedestal. And now he was turfed out like a partly cloudy day from a child’s memory, flicked off like an ant off a picnic blanket.
Litter was being chased up and down the aisle, wrapping around legs and trying to hide from the wind amongst commuters’ bags. He didn’t notice that the commuters were becoming concerned about the weather, heads turned to look outside where the clouds were blacker than night. Wind has beating on windows, knocking on doors trying to escape from itself. Loose objects were starting to drift.
“Puck, I’m so stupid!” Weather lamented aloud as a flash of lightning brightened the dusk for a second. He should have protected his research, patented it in his own name. Stupidly, he had thought he would be with GWI for the rest of his life. He had given his life over to GWI and they had thrown it away for an office in disarray. It might have looked like an unnatural disaster, but they could have at least let him evaluate their equipment to check for systems failure. Why he hadn’t opened his mouth and flung accusations back at them? Probably because they had looked angrier than he could possibly have gotten faced with a memory of shimmering blankness.
The weather was surreal, he casually noted it as something GWI would have to correct, something existing outside his present unemployed reality, their problem. His cellphone’s classic “Thunderstuck” ringtone charged the air.
“What’s happening with the weather, dude? I thought I read in the paper that it was supposed to be sunny skies and calm seas. I wanted to go for an evening dive at Devil’s.”
“I’ve no idea, I’ve been fired,” he managed to say calmly before he hung up.
“It’s not my responsibility,” he thought to himself and promptly switched his phone off. He had given his private cellphone number to a few select acquaintances he had tried to impress when he had just got his ‘prestigious’ job. He thought he might finally be able to get his social life out of his house by sharing information with people he had met in supermarkets, recognizing their faces from university. They were jocks obsessed about the weather for their hedonistic lifestyles and they had never invited him out, only phoning to find out about the weather.
He jumped off at his usual stop and leaned into the wind watching his feet moving past one another, his mind seething at the injustice of not having a fair trial where they showed him evidence of him been directly involved in the trashing of his office. He could only remember standing in the middle of it and his office revolving around him, but that was only a flash, there is nothing before that except the facts. Him working on algorithms of weather activation, them tinkering with the clouds. They were practically at the end of their testing, their final live weather event before taking on the whole world’s weather, he knows that, but everyday was still just the same as every other day, him at the computer, them throwing lightning bolts. “Puck! I should’ve challenged them,” he shouted into the howling wind at GSI with all the frustration of his past mistakes. But his voice was lost into the atmosphere.

2025-05-09 09:06:45In the rapidly evolving world of technology, edge computing has emerged as a game-changing innovation, reshaping how data is processed, analyzed, and delivered. Unlike traditional cloud computing, which relies on centralized data centers, edge computing processes data closer to the source—right where it's generated.
This shift is driven by the explosion of Internet of Things (IoT) devices, autonomous systems, and real-time applications that demand low latency and fast decision-making. From smart factories and self-driving cars to remote healthcare and AR/VR experiences, the need for real-time processing is fueling the growth of edge solutions.
Why Edge Computing Matters
As more devices connect to the internet, the volume of data being generated is staggering. Transmitting all this data to the cloud for processing can introduce delays and raise bandwidth costs. Edge computing addresses these challenges by enabling devices and local servers to handle tasks immediately, without having to send data back and forth to the cloud.
Key benefits include:
Reduced latency: Ideal for time-sensitive applications like autonomous vehicles and industrial automation.
Improved security: Sensitive data can be processed locally, minimizing exposure.
Cost efficiency: Reduces bandwidth and storage demands on central data centers.
Real-World Applications
-
Healthcare: Wearables and remote monitoring devices use edge computing to detect anomalies and alert physicians in real time.
-
Retail: Smart shelves and AI-powered cameras analyze consumer behavior on the spot.
-
Manufacturing: Machines use edge-based analytics to predict maintenance needs and prevent downtime.
Challenges Ahead
Despite its promise, edge computing is not without hurdles. Managing a distributed network of devices, ensuring consistent software updates, and maintaining security at the edge require robust frameworks and standards. Scalability and interoperability remain ongoing concerns for developers and organizations.
The Road Ahead
With the rollout of 5G and advancements in AI, edge computing is poised for massive growth. According to industry forecasts, the global edge computing market is expected to exceed $100 billion by 2030. As businesses continue to demand faster, smarter, and more secure tech infrastructure, edge computing will be at the heart of the next digital transformation.

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.

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.

2025-03-31 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.

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!

2025-05-11 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.

2025-03-23 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.

Proposal to Remove OP_RETURN Limit Sparks Heated Debate Among Developers
Introduced in 2014, OP_RETURN allows small pieces of data—like timestamps or short messages—to be included in Bitcoin transactions, serving as a lightweight method to store limited information on-chain. Over time, the size limit was reduced to prevent spam, before settling at the current 83 byte-limit.
Peter Todd recently proposed removing the limit entirely. He argues that the restriction fails to deter misuse and instead complicates things, as it pushes developers to use workarounds—like
scriptsig
or unspendable outputs (such as storing data in unspendable Taproot outputs)—to embed media, spam, or arbitrary data, which bloats the UTXO set.Pieter Wuille, who also supports lifting the OP_RETURN cap, points out that standardness policies can’t truly stop well-funded entities from broadcasting data-heavy transactions directly to miners. The network is strong and block space is always full—even without spam, so those rules are no longer as useful.
In short, those in favor of removing the OP_RETURN limit argue that the restriction is futile, and that alternative data storage methods within blocks already exist in abundance.
On the other side, opponents believe the limit must stay, as using OP_RETURN to store arbitrary data violates Satoshi’s intent and Bitcoin’s purpose as a financial network (Luke Dashjr). Other opposing voices include:
- @Mechanic from Ocean Mining: The devs just instinctively knew, you don’t use Bitcoin for arbitrary file storage and you do everything you can to make Bitcoin awkward to use for that purpose.
- Jason Hughes: Bitcoin Core developers are about to merge a change that turns Bitcoin into a worthless altcoin…
Here for more perspectives on this debate.
Comparing Three Cluster Linearization Techniques
Pieter Wuille compares three cluster linearization strategies—SFL (spanning-forest linearization), GGT, and CSS (candidate set search)—and follows up with benchmark results for each.

Round-Efficient Adaptively Secure Threshold Signatures with Rewinding
A threshold signature scheme allows distributing a signing key to n users, such that any t of them can jointly sign, but any t−1 cannot. It is desirable to prove adaptive security of threshold signature schemes, which considers adversaries that can adaptively corrupt honest users even after interacting with them. For a class of signatures that relies on security proofs with rewinding, such as Schnorr signatures, proving adaptive security entails significant challenges. This work proposes two threshold signature schemes that are provably adaptively secure with rewinding proofs. Our proofs are solely in the random oracle model (ROM), without relying on the algebraic group model (AGM).

Vitalik on Simplifying Ethereum L1, Taking Cues from Bitcoin’s Minimalism
In a new post titled Simplifying the L1, Vitalik suggests simplifying Ethereum’s base layer by moving from EVM to RISC-V (or another minimal VM), adopting Simple Serialize, and embracing Tinygrad’s coding philosophy.
Key impacts of this shift include:
- Radical efficiency improvements: Contracts can run directly in ZK provers without interpreter overhead. According to Succinct, performance could increase by over 100x in many cases.
- Radically improved simplicity: RISC-V spec is far more minimal than the EVM. Other options like Cairo also offer a simple design.
- All the benefits that motivated Ethereum Object Format (EOF): Including code sections, friendly static analysis, and larger code size limits.
- Expanded tooling: Solidity and Vyper can target the new VM with backend updates. If RISC-V is chosen, developers may be able to port existing code from mainstream languages.
- Reduced reliance on precompiles: Most precompiles may become obsolete—except perhaps highly optimized elliptic curve operations, which could also be phased out with advances in quantum computing.

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.

2025-05-11 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.

2025-05-09 01:49:00加密洞见
取消 OP_RETURN 限制?引发比特币开发者激辩论
OP_RETURN 于 2014 年推出,允许将小块数据(如时间戳或短消息)包含在比特币交易中,作为在比特币链上存储有限信息的轻量级方式。出于防止垃圾信息的考虑,OP_RETURN 当前的大小限制是 83 字节。
Peter Todd 最近提议完全取消该限制。他认为该限制无法有效遏制滥用,反倒让事情更加复杂。因为它迫使一些开发人员采用各种变通方式——如使用 scriptsig 或不可花费输出(比如这里介绍了在无法花费的 Taproot 输出上存储数据的方式)——来存储媒体、垃圾信息和其他任意数据,这会导致 UTXO 集膨胀。
Pieter Wuille 同样主张 取消 OP_RETURN 限制。他认为,标准性策略并不太可能真正阻止那些由资金充足的组织创建的数据交易被确认——这些组织会将交易直接发送给矿工。此外,现在网络中的区块基本始终满载——即便是没有垃圾信息——因此 OP_RETURN 限制这样的规则已经没有效用。
总之,支持取消 OP_Return 限制一方的理由是,该限制是徒劳的,区块内已经有其它数据存储的替代方案。
反对该提案的一方则认为必须保留该限制,因为通过 OP_Return 存储任意数据违反了中本聪的初衷,也偏离了比特币作为金融网络的核心目的(Luke Dashjr)。其他反对意见包括: - 来自 Ocean Mining 的 @Mechanic:「开发者凭直觉就知道,不应用比特币来存储任意文件,而且应该尽一切可能让比特币难以用于这个目的。」 - Jason Hughes:「Bitcoin Core 开发人员即将合并一项将比特币变成毫无价值的山寨币的更改」……

带回绕的轮次高效自适应安全门限签名方案
门限签名方案允许将一个签名密钥分发给 n 个用户,使得其中任意 t 个用户可以联合生成签名,但任意 t−1 个用户则无法做到这一点。研究者希望门限签名方案(Threshold Signatures)能具备自适应安全性,即在面对能够在交互后动态腐化诚实用户的对手时仍然保持安全。对于一类依赖带回绕(rewinding)证明的签名方案(如 Schnorr 签名),证明其自适应安全性是一个重大挑战。论文提出了两种在带回绕证明下可证明具备自适应安全性的门限签名方案。其安全性证明完全基于随机预言机模型(ROM),不依赖代数群模型(AGM)。

以太坊如何简化 L1,实现对标比特币的简洁架构
Vitalik 近日发表 Simplifying the L1 ,建议简化以太坊 L1,从 EVM 迁移到 RISC-V(或其他最小 VM),采用「简单序列化」(Simple Serialize),仿效 Tinygrad 的简洁代码风格。
特别地,关于 RISC-V,Vitalik 认为这一转变会带来:
- 效率革命性提升:在 ZK 证明者内部,智能合约可直接执行,无需解释器开销。Succinct 数据显示,在多数场景下性能可提升百倍以上。
- 结构极致简化:RISC-V 规范相较于EVM 极为精简,其他候选方案(如 Cairo)同样具备简洁特性。
- 继承 EOF 的所有优势:包括代码分段管理、更友好的静态分析支持,以及更大的代码容量限制。
- 开发者工具链扩展:Solidity 和 Vyper 可通过新增后端编译支持新架构;若选择 RISC-V,主流语言开发者可直接移植现有代码。
- 消除对大部分预编译的要求:也许除了保留高优化的椭圆曲线运算外,大部分预编译功能将不再必要(而椭圆曲线也许也会随量子计算发展被淘汰)。

2025-05-09 01:07:20ถ้าย้อนกลับไป 50 ปีก่อน ถ้าเฮียถามคำนี้กับลุงชาวนาคนหนึ่ง เขาคงหัวเราะแล้วตอบแบบไม่ต้องคิดว่า “ก็เจ้าของที่นาไงไอ้ทิด จะมีใครล่ะ?”
แต่พอมาในวันนี้ ถ้าเฮียถามคำเดิมในซูเปอร์มาร์เก็ต คงไม่มีใครกล้าตอบแบบนั้นอีกแล้ว เพราะแค่ในชั้นวางโยเกิร์ตเดียวกัน เฮียอาจเห็นยี่ห้อต่างกัน 10 ยี่ห้อ แต่ทั้งหมดอาจเป็นของบริษัทแม่เพียงเจ้าเดียว
ในศตวรรษที่ 21 อาหารไม่ใช่ของคนทำอาหาร แต่มันกลายเป็นของ บริษัทผู้ครอบครองข้อมูล พันธุกรรม และระบบการกระจายสินค้า โลกวันนี้ไม่ได้มีเกษตรกรล้อมวงเคี้ยวหมาก แต่มีบริษัทเทคโนโลยีจับมือกับนักลงทุนระดับโลก ถือครองเมล็ดพันธุ์ เป็นเจ้าของสิทธิบัตรจุลินทรีย์ในลำไส้ และมีอำนาจเสนอว่า “อาหารแบบไหนควรได้รับเงินสนับสนุนจากรัฐ”
บริษัทเทคโนโลยีในซิลิคอนแวลลีย์บางแห่ง ไม่ได้แค่ผลิตซอฟต์แวร์อีกต่อไป แต่เริ่มทำ "อาหารจากโค้ด" โปรตีนสังเคราะห์ที่ได้จากการแทรกยีน หรือแม้แต่ “อาหารจากคาร์บอนในอากาศ” ที่สร้างโดย AI เขาไม่ได้ปลูกข้าว แต่เขาเขียนสูตรให้เครื่องจักรสร้างอาหารในถัง
ใครมีสิทธิบัตร…คนนั้นคือเจ้าของ ใครควบคุมข้อมูลสุขภาพ…คนนั้นคือนายทุนแห่งความหิว และใครสามารถชี้นิ้วให้รัฐบาลเปลี่ยนนโยบายอาหารโรงเรียน…คนนั้นคือเจ้าของอนาคตของเด็กทั้งประเทศ
มันฟังดูเวอร์ใช่ไหม? แต่ลองดูดี ๆ…ใครเป็นเจ้าของฟาร์มหมู ฟาร์มไก่ โรงฆ่าสัตว์? หลายแห่งไม่ได้เป็นของชาวบ้านอีกต่อไป แต่เป็นของเครือบริษัทยักษ์ใหญ่ที่อยู่เบื้องหลังทั้งอาหารในซูเปอร์ และเม็ดวิตามินในกระปุกเฮียด้วย
ยิ่งไปกว่านั้น เจ้าของตัวจริงไม่ได้อยู่ในร้านของชำ แต่ซ่อนตัวอยู่ในบอร์ดบริหารบริษัทเกษตรข้ามชาติ ในเวทีประชุมเศรษฐกิจโลก และในห้องประชุมที่ตัดสินว่า “อาหารจากวัว” ควรถูกเก็บภาษีคาร์บอนเพิ่มหรือไม่
เมื่อก่อนเฮียเคยคิดว่า ถ้าเราปลูกผักเอง ก็คุมอาหารตัวเองได้ แต่พอระบบเริ่มขับไล่เมล็ดพันธุ์ดั้งเดิมให้สูญพันธุ์ ถ้าไม่มีใบอนุญาตปลูกพืช GMO หรือไม่มีเงินซื้อปุ๋ยจากบริษัทเดียวที่ยังอยู่รอด เกษตรกรจะเป็นเจ้าของอะไรกันแน่?
และคำว่า “อาหารอิสระ” ในยุคนี้ อาจไม่ใช่แค่การไม่พึ่งพาซูเปอร์ แต่มันคือ “การตื่นรู้ว่าใครเป็นคนจัดเกม และใครเป็นคนตั้งกฎ”
เพราะในยุคที่ทุกอย่างแปรรูปเป็นดิจิทัล แม้แต่อาหารก็อาจมีเจ้าของเพียงไม่กี่ราย และสิ่งที่น่ากลัวกว่าผูกขาด…คือการ “ผูกอนาคต” ของเราทั้งมื้อ

2025-05-11 18:39:10Originalni tekst na antenam.net
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.

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.

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.

🔐 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. 🚀

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.

2025-05-08 14:42:20Introduction: The Challenge of Bitcoin-Secured Loans
Bitcoin holders often face a dilemma: they need liquidity but don't want to sell their assets, potentially missing out on future gains or triggering taxable events. Bitcoin-secured loans offer a solution, allowing users to borrow cash (like digital dollars) using their Bitcoin as collateral. However, the current landscape is fraught with challenges. Many existing solutions require users to trust centralized entities or involve complex mechanisms like wrapping Bitcoin, exposing them to significant risks:
- Custodial Risk: Handing over your Bitcoin to a third party means trusting they won't lose it, misuse it, or become insolvent. Billions have been lost this way.
- Smart Contract Risk: Platforms built on chains like Ethereum rely on complex smart contracts, which can contain bugs or vulnerabilities exploitable by hackers.
- Oracle Risk: Loan systems need reliable price feeds (oracles) to manage collateral. Centralized or manipulatable oracles can lead to unfair liquidations.
- Privacy Risk: Loan details and transactions are often publicly visible on the blockchain.
- Complexity and Cost: Existing processes can be slow, require extensive documentation, and involve high fees.
There's a clear need for a better way – one that is simple, reliable, and minimizes trust. This is where the Lava Loans Protocol comes in.
What is Lava Loans?
In simple terms, Lava Loans provides a way to borrow digital dollars using your native Bitcoin as collateral, directly from your own vault. It's designed to be:
- Simple & Fast: Get a loan in seconds with minimal questions asked.
- Low-Cost & Flexible: Offers competitive rates, dynamic fee structures, and allows borrowing any amount.
- Reliable & Trust-Minimized: Leverages Bitcoin's own capabilities to reduce reliance on intermediaries and enhance security.
How Lava Loans Addresses the Risks
Lava tackles the common pitfalls of crypto loans head-on:
- Eliminating Custodial Risk: Instead of transferring your Bitcoin to a custodian or wrapping it, Lava uses native Bitcoin locked directly on the Bitcoin network within a special type of contract. This prevents rehypothecation and loss through hacks or confiscation.
- Minimizing Smart Contract Risk: Lava utilizes Bitcoin smart contracts, also known as Discreet Log Contracts (DLCs). These are designed to be less complex and more secure than many general-purpose smart contracts, with outcomes pre-defined and formally verified.
- Reducing Oracle Risk: Users choose their own off-chain, blinded oracles (called Sibyls) for price data, with enhanced redundancy to ensure reliability. Off-chain attestations avoid high fees and miner manipulation risks associated with on-chain oracles. Blinded oracles provide price data without knowing the specific contract they influence, preventing targeted attacks.
- Enhancing Privacy: Because DLCs operate differently from typical public smart contracts, the details of the loan contract are not broadcast publicly on the Bitcoin blockchain.
- Trustless Initiation & Repayment: Atomic swaps ensure that collateral only moves to the contract once the loan is received, and collateral is automatically returned upon verified repayment.
The Magic Ingredients: DLCs and Sibyls Oracles
Two core technologies make Lava Loans unique:
-
Discreet Log Contracts (DLCs): Think of a DLC as a pre-programmed Bitcoin transaction agreed upon by the borrower and lender. Before the loan starts, they define all possible outcomes (e.g., repayment, liquidation at a specific price, expiry) and create encrypted signatures for each. The Bitcoin collateral is locked in a multisig output controlled by these pre-signed transactions. Only the conditions agreed upon (verified by oracle signatures) can unlock the funds according to the pre-defined rules. This offers:
- Security: Formally verified, pre-defined outcomes minimize bug risk.
- Privacy: Contract details remain off-chain.
- Scalability: Minimal on-chain footprint as execution logic is off-chain.
- Customization: Users can choose their own oracles and LTV thresholds.
-
Sibyls Oracles: These are the independent price feed providers for Lava. Key characteristics include:
- Off-Chain: Attestations happen off-chain, avoiding blockchain fees and manipulation.
- User-Chosen: Borrowers select the oracles they trust for each loan.
- Blinded: Oracles provide signed price data without knowing the specific DLC it applies to, enhancing security.
- Redundant: Multiple oracles can be configured to provide fallback price feeds, reducing the risk of oracle failure.
System Overview
Here's a high-level look at the components involved in the Lava Loans ecosystem:
[ Borrower ] --(locks Bitcoin)--> [ DLC Contract (Bitcoin) ] [ Lender ] --(sends stablecoins)--> [ Alt-Chain Contract (Solana) ] [ Oracles ] --(provides price)--> [ DLC Contract (Bitcoin) ] [ Borrower ] --(repays loan)--> [ Alt-Chain Contract (Solana) ] [ Lender ] --(claims collateral)--> [ DLC Contract (Bitcoin) ]
The Lava Loan Lifecycle
A loan progresses through several states:
- Initialized: A trustless atomic swap occurs. The borrower locks Bitcoin collateral into the DLC on the Bitcoin network, and the lender locks the loan capital (e.g., digital dollars on a network like Solana using HTLCs) which the borrower then claims.
- Active: The collateral is secured in the DLC, and the borrower has the loan capital. The Lava Protocol monitors the loan-to-value (LTV) ratio using price data from the chosen Sibyls oracles, with customizable LTV thresholds for greater flexibility.
- Terminated: The loan concludes in one of several ways:
- Repaid: The borrower repays the loan capital plus interest on the loan asset network, with dynamic fees adjusting based on network conditions. Upon verification, the DLC automatically releases the Bitcoin collateral back to the borrower.
- Liquidated: If the Bitcoin price drops and the LTV reaches a pre-determined threshold (now more flexible to avoid premature liquidations), the DLC automatically releases the collateral to the lender.
- Expired: If the loan term ends before repayment, the DLC releases an amount equivalent to the principal plus interest to the lender, and the remaining collateral is returned to the borrower.
- Fail-safe: In rare cases of unresponsive oracles, redundant Sibyls oracles and built-in mechanisms ensure collateral is not permanently lost.
Loan Process Sequence
The following diagram illustrates the typical sequence of events in a Lava Loan:
1. Borrower --> DLC: Create loan contract with collateral 2. Lender --> Alt-Chain: Fund loan with stablecoins 3. Borrower --> Alt-Chain: Receive and use stablecoins 4. (If repayment) 4a. Borrower --> Alt-Chain: Repay loan 4b. Lender --> Alt-Chain: Confirm repayment 4c. Borrower --> DLC: Claim collateral 5. (If liquidation) 5a. Oracle --> DLC: Provide price attestation 5b. Lender --> DLC: Claim collateral 6. (If expiry) 6a. Borrower/Lender --> DLC: Split collateral
Lava Loans vs. Other Bitcoin Lending Platforms: A Quick Comparison
How does Lava stack up against typical DeFi lending protocols and other Bitcoin lending platforms like Unchained, Strike, and Coinbase?
| Feature | Lava Loans (Bitcoin) | Typical Ethereum DeFi | Unchained | Strike | Coinbase | | :------------------- | :---------------------------------------------------- | :-------------------------------------------------------- | :---------------------------------------------------- | :---------------------------------------------------- | :---------------------------------------------------- | | Collateral | Native Bitcoin | Often Wrapped Bitcoin (wBTC) or other assets | Native Bitcoin | Native Bitcoin | Native Bitcoin | | Contract Type | Discreet Log Contracts (DLCs) - Pre-agreed, Private | Smart Contracts - Public, Complex, Run on EVM | 2/3 Multisig Vaults | Custodial Contracts | Custodial Contracts | | Security | Aims for higher security via simpler, pre-set DLCs | Can be complex, potential for bugs/exploits | Secure via multisig, but relies on key holders | Custodial, less transparent | Custodial, less transparent | | Privacy | Higher privacy (contract details off-chain) | Lower privacy (contract interactions often public) | Moderate privacy (multisig details on-chain) | Lower privacy (custodial model) | Lower privacy (custodial model) | | Oracles | User-chosen, Off-chain, Blinded (Sibyls) | Often On-chain, potentially manipulatable | Not applicable (manual monitoring) | Centralized oracles | Centralized oracles | | Trust | Designed to minimize trust in intermediaries | Often requires trust in custodians, bridges, or protocols | Moderate trust (key holders could collude) | Higher trust (custodial, opaque practices) | Higher trust (custodial, opaque practices) | | Rehypothecation | No rehypothecation, verifiable on-chain via DLCs | Possible, depends on protocol | No rehypothecation, secured by multisig | Opaque, likely rehypothecated | Opaque, likely rehypothecated | | Interest Rates | Competitive, typically lower due to non-custodial model | Varies, often 5-10% for wBTC loans | 11-14% for non-rehypothecated loans | 12-13% (implies rehypothecation) | ~5-6% (implies rehypothecation) |
Lava leverages Bitcoin’s native capabilities and a specific oracle design to prioritize security, privacy, and trust minimization. Unlike Unchained, which uses a 2/3 multisig where two key holders could potentially collude, Lava’s DLCs ensure cryptographic proof of non-rehypothecation, verifiable on-chain in real time. Strike and Coinbase, being custodial, lack transparency about rehypothecation practices, with market rates suggesting they rehypothecate collateral. The v3 protocol introduces dynamic fee adjustments and more flexible LTV thresholds, reducing premature liquidations and optimizing costs based on network conditions.
Conclusion
Lava Loans presents a compelling option for those seeking liquidity against their Bitcoin holdings without sacrificing security or control. By utilizing Discreet Log Contracts, a user-centric, blinded oracle system (Sibyls) with enhanced redundancy, and new features like dynamic fees and flexible LTV thresholds, Lava provides a simple, reliable, and trust-minimized borrowing experience. These advancements directly address the major pain points found in many existing centralized and decentralized lending platforms.

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.

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.

2025-05-08 14:35:02Money has always been more than a medium of exchange. It reflects what societies value, how they organize trust, and what they choose to remember. This article explores the idea that money functions as a form of collective memory, and how Bitcoin may be restoring this role in a new way.
The Asante Example
In the Asante Empire, which flourished in West Africa during the 18th and 19th centuries, gold dust served as the primary medium of exchange. To measure it, traders used ornate spoons made of brass. These spoons were often carved with birds, animals, or abstract symbols. They were not currency themselves, but tools used to handle gold dust accurately.
Importantly, these spoons also carried meaning. Symbols and proverbs embedded in the spoons conveyed lessons about honesty, community, and continuity. For example, the Sankofa bird, shown turning its head backward to retrieve an egg from its back, represented the proverb, “It is not wrong to go back for that which you have forgotten.” This was a reminder to learn from the past.
The spoons reflect an understanding that money and its instruments are not just practical tools. They are cultural artifacts that store shared values. In the Asante context, even measurement was ritualized and tied to ethics and memory.
Money as a Cultural Medium
This connection between money and cultural meaning is not unique to the Asante Empire. Modern fiat currencies also carry symbols, phrases, and designs that reflect national identity and political values.
The U.S. dollar includes Latin phrases and national symbols meant to convey stability and purpose. The British pound features royal iconography, reinforcing the idea of continuity and sovereignty. When the euro was introduced, it deliberately avoided specific national references. Itsdesign used bridges and windowsto suggest openness and cooperation across the continent.
These design choices show that societies still embed meaning into their money. Even in a digital or fiat context, money is used to transmit a story about who we are, where authority lies, and what we value.
The Fragility of Fiat Memory
While fiat money carries cultural symbols, the narratives behind those symbols can be fragile.
In 2021, the central bank of the Philippines removed democratic leaders from its banknotes,triggering public criticism. In the United States, attempts to replace Andrew Jackson with Harriet Tubman on the $20 billfaced repeated delays. These examples show how political control over money includes control over what stories are told and remembered.
Unlike objects passed down through generations, fiat memory can be edited or erased. In this sense, it is vulnerable. The meaning encoded in fiat systems can shift depending on who holds power.
Bitcoin as a New Form of Memory
Bitcoin is described as digital money. But it also introduces a different model of how societies can record value and preserve meaning.
The Bitcoin network launched in 2009 with a small message embedded in its first block: “Chancellor on brink of second bailout for banks.” This was a reference to a newspaper headline that day and a clear sign of protest against financial bailouts, centralized monetary policy, and forever wars.
This moment marked the beginning of a system where memory is stored differently. Instead of relying on governments or institutions, Bitcoin stores its history on a public ledger maintained by a decentralized network of participants. Its memory is not symbolic or political; it is structural. Every transaction, every block, is preserved through time-stamped computation and consensus.
No single authority can change it. The rules are clear and publicly auditable. In this way, Bitcoin offers a version of money where memory is both neutral and resilient.
Cultural Expression and Community Values
Even though Bitcoin lacks the traditional symbols found on banknotes, it has developed its own culture. Phrases like “Don’t trust, verify” or “Stay humble, stack sats” are shared widely in the Bitcoin community. These ideas reflect a focus on self-responsibility, verification, and long-term thinking.
These proverbs can be compared to the carved messages on the Asante spoons. While the contexts are very different, the underlying idea is similar: a community using language and symbols to reinforce its shared values.
Bitcoin also has a well established and growing art scene. Bitcoin conferences often feature dedicated sections for art inspired by the protocol and its culture. Statues of Satoshi Nakamoto have been installed in cities like Budapest, Lugano, and Fornelli. These physical works reflect the desire to link Bitcoin’s abstract values to something tangible.
Looking Back to Look Forward
The Asante example helps us see that money has long been tied to memory and meaning. Their spoons were practical tools but also cultural anchors. Bitcoin, while new and digital, may be playing a similar role.
Instead of relying on political symbols or national myths, Bitcoin uses code, transparency, and global consensus to create trust. In doing so, it offers a way to preserve economic memory that does not depend on power or politics.
It’s still early to know what kind of legacy Bitcoin will leave. But if it succeeds, it may not just change how money works. It may also change how civilizations remember.

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 18:22:40Originalni tekst na antenam.net
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.
