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.

2025-05-10 09:36:24In today's hyper-connected world, the concept of freedom has taken on new dimensions. With every click, swipe, and search, we contribute to a vast digital footprint that shapes how we are seen and how we interact with the world. But as technology advances, so too does the tension between digital convenience and the right to personal privacy.
The Digital Landscape
The rise of the internet has democratized information, connecting billions of people across the globe. Social media platforms allow for unprecedented levels of communication, giving a voice to the voiceless and a platform for activism. However, this connectivity comes with a price—our personal information.
The Cost of Convenience
From targeted ads to personalized recommendations, our online behaviors are tracked, analyzed, and sometimes exploited. While this can enhance user experience, it also raises questions about how much of our freedom is being surrendered in exchange for convenience. Are we willingly giving up our privacy for the sake of digital ease?
Privacy vs. Security
Governments and corporations argue that data collection is necessary for security and better services. However, this often blurs the lines between protection and intrusion. When is it acceptable for private information to be shared, and where should the boundaries be drawn?
Protecting Digital Freedom
-
Know Your Rights: Understand the privacy policies of the platforms you use.
-
Use Encryption: Protect your personal communications with encrypted services.
-
Limit Data Sharing: Be mindful of the information you share online.
-
Support Digital Rights: Advocate for stronger data protection laws.
The Path Forward
As technology continues to evolve, so must our understanding of freedom in the digital realm. True digital freedom is not just about access; it is about control—control over our information, our choices, and our online identities.
“The price of freedom is eternal vigilance.” — Thomas Jefferson
In this digital age, that vigilance must extend to the virtual world, where our freedoms are just as valuable and just as fragile.

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.

2025-05-10 08:09:15บทที่ 3: ตะวันออกแห่งเอเดน (East of Eden)
บทนี้เจาะลึกต้นกำเนิดของโครงสร้างอำนาจในมนุษยชาติผ่านมุมมองเชิงประวัติศาสตร์และเศรษฐศาสตร์ โดยเฉพาะการเปลี่ยนแปลงครั้งสำคัญที่เรียกว่า การปฏิวัติเกษตรกรรม ซึ่งพลิกโฉมวิถีชีวิตมนุษย์จากการเป็นนักล่าสัตว์และเก็บของป่า มาสู่สังคมที่ตั้งถิ่นฐานถาวร สะสมทรัพย์สิน และมีแนวโน้มที่จะใช้ความรุนแรงและจัดองค์กรทางอำนาจที่ซับซ้อนมากขึ้น
การเปลี่ยนผ่านดังกล่าวสามารถเห็นภาพได้อย่างคมชัดผ่านสัญลักษณ์ในพระคัมภีร์ไบเบิล จากเรื่องราวของคาอินและอาเบล:
“และพระเจ้าตรัสกับคาอินว่า ‘อาเบล น้องชายของเจ้าอยู่ที่ไหน?’ คาอินตอบว่า ‘ข้าพระองค์ไม่ทราบ ข้าพระองค์เป็นผู้ดูแลน้องชายของข้าหรือ?’ พระเจ้าตรัสว่า ‘เจ้าทำอะไรลงไป? เสียงเลือดของน้องชายเจ้าร้องต่อเรามาจากพื้นดิน’” (ปฐมกาล 4:9-10)
นี่ไม่ใช่เพียงบทสนทนาทางศาสนา แต่สามารถตีความในเชิงสัญลักษณ์ว่าเป็นการบันทึกครั้งแรกของอาชญากรรมที่เกิดจากตรรกะของการเป็นเจ้าของและความรุนแรง คาอิน ผู้เป็น “ชาวนา” ได้สังหารน้องชายของตนเองจากแรงริษยาและการแข่งขันในบริบทของการถวายผลผลิต ความเปรียบเปรยนี้สะท้อนถึงความเปลี่ยนแปลงของตรรกะทางสังคมเมื่อมนุษย์เข้าสู่ยุคเกษตรกรรม
ในยุคก่อนเกษตรกรรม มนุษย์อยู่กันเป็นกลุ่มเล็ก ๆ พึ่งพาทรัพยากรธรรมชาติในพื้นที่กว้าง ไม่มีแรงจูงใจจะใช้ความรุนแรง เพราะไม่มีทรัพย์สินให้แย่งชิง อาหารต้องบริโภคทันที ไม่มีการสะสม ทำให้ไม่มีใครร่ำรวยหรือยากจนอย่างชัดเจน โครงสร้างสังคมจึงเท่าเทียมและร่วมมือกันได้ดี
แต่เมื่อมนุษย์เริ่มเพาะปลูกและเลี้ยงสัตว์ พื้นที่การผลิตอาหารต้องได้รับการดูแลต่อเนื่อง ทำให้ไม่สามารถอพยพหนีภัยได้ง่าย และเมื่อมีผลผลิตมากขึ้น ก็ยิ่งเป็นเป้าหมายของการปล้นสะดม ส่งผลให้กลุ่มนักรบผู้ใช้ความรุนแรงสามารถสะสมทรัพยากรและอำนาจได้มากขึ้น และบางกลุ่มก็พัฒนาเป็นรัฐ ระบบการป้องกันและการเก็บส่วยในรูปแบบของรัฐจึงค่อยๆ ก่อตัวขึ้นจากพันธมิตรระหว่างนักรบกับนักบวช
ทรัพย์สิน ส่วนตัวซึ่งไม่เคยมีความสำคัญในสังคมนักล่าสัตว์ กลายเป็นสิ่งที่จำเป็นในสังคมเกษตรกรรม เพราะไม่มีใครจะเพาะปลูกด้วยแรงงานของตนเองหากรู้ว่าจะถูกปล้นไป ความชัดเจนของกรรมสิทธิ์จึงเป็นสิ่งจำเป็น แต่ขณะเดียวกัน กลไกของความรุนแรงก็ทำให้สิทธิในทรัพย์สินตกอยู่ในความเสี่ยง ระบบของรัฐในยุคแรกจึงเป็นการผูกขาดความรุนแรงในนามของความคุ้มครอง
ในสังคมเกษตรกรรมที่ผลิตภาพต่ำ ผู้คนจำนวนมากต้องพึ่งพารูปแบบการป้องกันทางเศรษฐกิจที่เรียกว่า “หมู่บ้านปิด” ซึ่งความเสี่ยงถูกกระจายระหว่างเจ้าของที่ดินกับชาวนา โดยมีหัวหน้าหมู่บ้านเป็นตัวกลางในความสัมพันธ์ทางเศรษฐกิจ การจ่ายค่าเช่าที่ดินในรูปแบบผลผลิตแทนเงิน ช่วยให้เจ้าของที่ดินและผู้เช่าสามารถรับมือกับภัยพิบัติร่วมกันได้ในปีที่ผลผลิตตกต่ำ
พฤติกรรมหลีกเลี่ยงความเสี่ยงนี้จำกัดการเติบโตและนวัตกรรมในระบบเศรษฐกิจ เนื่องจากโอกาสในการอยู่รอดมีค่าสูงกว่าความหวังต่อความมั่งคั่ง และนำไปสู่การครอบงำของวัฒนธรรมที่กดทับพฤติกรรมแปลกแยก วัฒนธรรมจึงเป็นกลไกปรับตัวที่เหมาะสมกับความแร้นแค้น ไม่ใช่เครื่องมือในการเปิดโอกาส
ในพื้นที่ที่เกษตรกรรมมีผลิตภาพสูง เช่น กรีซโบราณ กรรมสิทธิ์ส่วนตัว การออม และการเลื่อนสถานะทางสังคมก็เริ่มปรากฏ แต่ในพื้นที่ส่วนใหญ่ของโลก ระบบศักดินาครอบงำ เพราะผลิตภาพต่ำและมีความจำเป็นต้องพึ่งพาอำนาจผูกขาดความรุนแรง
บทนี้ยังวิเคราะห์การเปลี่ยนผ่านจากยุคโรมันไปสู่ยุคกลาง โดยเฉพาะ การปฏิวัติศักดินา ราวปี ค.ศ. 1000 การล่มสลายของจักรวรรดิโรมันทำให้รัฐอ่อนแอ และเปิดโอกาสให้ชาวนารายย่อยมีอิสระมากขึ้นในยุคมืด แต่เมื่อประชากรเพิ่มขึ้น ภูมิอากาศแปรปรวน และภัยพิบัติเกิดขึ้นต่อเนื่อง ผลผลิตตกต่ำ ชาวนาไม่สามารถรักษากรรมสิทธิ์ของตนไว้ได้ ต้องมอบที่ดินให้กับผู้มีอำนาจเพื่อแลกกับความคุ้มครอง กระบวนการนี้ค่อย ๆ เปลี่ยนเจ้าของที่ดินรายย่อยให้กลายเป็นไพร่ในระบบศักดินา
กองกำลังติดอาวุธ เช่น อัศวินม้า มีบทบาทสำคัญในการรวมอำนาจ เพราะมีต้นทุนการจัดหาสูงจนชาวนาทั่วไปไม่สามารถแข่งขันได้ โบสถ์จึงเข้ามามีบทบาทในการจำกัดความรุนแรงผ่านขบวนการ สันติภาพของพระเจ้า และยังมีบทบาทในเชิงโครงสร้างอื่น ๆ เช่น การศึกษา การจัดเก็บความรู้ การพัฒนาเกษตรกรรม และการก่อสร้างโครงสร้างพื้นฐาน เช่น ถนน เขื่อน และโรงสี
ตรรกะของความรุนแรงเปลี่ยนไปอย่างสิ้นเชิงในยุคเกษตรกรรม เพราะทรัพย์สินสามารถแย่งชิงได้ มีต้นทุนในการปกป้อง และผลตอบแทนที่คุ้มต่อการลงทุนในอาวุธ ความรุนแรงจึงกลายเป็นสิ่งที่ “คุ้มค่า” ทางเศรษฐศาสตร์เป็นครั้งแรกในประวัติศาสตร์
บทสรุปของบทนี้ชี้ให้เห็นว่า การเปลี่ยนแปลงจากยุคนักล่าสัตว์มาสู่การเกษตรคือจุดเริ่มต้นของระบบอำนาจ และเสรีภาพส่วนบุคคลถูกลดทอนลงเรื่อย ๆ เพื่อตอบสนองต่อความมั่นคงของทรัพย์สิน ในแง่นี้ เรื่องราวของคาอินผู้สังหารน้องชาย ซึ่งเป็นคนเลี้ยงสัตว์ สะท้อนถึงการก้าวเข้าสู่ยุคใหม่ที่การเพาะปลูกไม่เพียงสร้างอารยธรรม แต่ยังเปิดประตูสู่ตรรกะของการใช้ความรุนแรงอย่างเป็นระบบ

2025-05-10 07:19:47Relays play a crucial role in the Nostr communication protocol, serving as the backbone of its decentralized architecture. Here’s an overview of their functions and significance:
Functions of Nostr Relays
-
Data Storage and Broadcasting: Relays act as intermediaries that store and distribute messages between users. When a user sends a message, it is transmitted to one or more relays, which then broadcast that message to other connected clients. This decentralized approach ensures that no single entity controls the flow of information, enhancing censorship resistance[1][2][6].
-
Interoperability: Users can connect to multiple relays simultaneously, allowing them to access the same content across different applications. This interoperability means that messages can be shared and retrieved from various clients without being tied to a specific platform, promoting a more flexible user experience[4][11].
-
User Control: Anyone can run their own relay, which empowers users to maintain control over their data and interactions. By operating a personal relay, users can ensure that their messages are stored and accessible without relying on third-party services, thus enhancing privacy and security[3][7][11].
-
Performance and Reliability: The performance of a Nostr client can be influenced by the relays it connects to. If a relay is slow or unreliable, it can affect the overall user experience. Users are encouraged to choose or add multiple relays to improve message delivery speed and reliability[7][8][11].
Types of Relays
-
Public and Private Relays: There are both public and private relays available. Public relays are free to use, while private relays may charge fees. Paid relays often provide better performance and reduced spam, as the cost can deter malicious users from flooding the network with unwanted content[6][7][14].
-
Self-Hosted Relays: For those who want maximum control and privacy, setting up a self-hosted relay is an option. This allows users to manage their own data and ensure that their communications are not subject to external censorship or data loss[4][7].
In summary, relays are essential to the Nostr protocol, facilitating decentralized communication by storing, broadcasting, and managing messages across a network of users. They enhance user autonomy, improve performance, and contribute to the overall resilience of the Nostr ecosystem.

2025-05-10 07:06:45Nostr, which stands for "Notes and Other Stuff Transmitted by Relays," is a decentralized communication protocol designed to facilitate the exchange of messages without relying on centralized servers. This innovative framework allows users to create, broadcast, and receive messages freely, emphasizing user empowerment and censorship resistance.
Key Features of Nostr
-
Decentralization: Unlike traditional social media platforms, Nostr operates on a network of relays, which are servers that anyone can run. This structure eliminates the control that a single entity can exert over the platform, thereby reducing the risk of censorship and enhancing user privacy[1][4][5].
-
Open Protocol: Nostr is not an application itself but a protocol that developers can use to build various applications. This openness allows for a wide range of services, from social media to messaging, all built on the same underlying technology. Users can access multiple applications using a single public/private key pair, making it easier to manage their online identities[2][3][4].
-
Censorship Resistance: One of the primary motivations behind Nostr's creation is to provide a platform where users can communicate without fear of censorship. This is particularly appealing to those disillusioned with traditional social media platforms that often impose restrictions on content[5][10].
-
User Control: Nostr empowers users by allowing them to control their data and interactions. Users can choose which relays to connect to and can run their own relays, ensuring that they are not dependent on any single service provider[4][5][7].
-
Cryptographic Security: The protocol employs public-key cryptography to secure messages and verify identities, similar to how Bitcoin operates. This ensures that messages are authentic and have not been tampered with during transmission[5][10].
Applications and Community
Nostr has gained traction among various communities, particularly within the cryptocurrency space, where figures like Jack Dorsey and Edward Snowden have expressed support for its potential to reshape online communication. The protocol's design allows for a variety of applications, including social media platforms, chat services, and content sharing tools, all of which can interoperate seamlessly[2][3][5].
In summary, Nostr represents a significant shift in how digital communication can be structured, prioritizing decentralization, user autonomy, and resistance to censorship, making it a compelling alternative to conventional social media platforms.

Montando Sistema de Arquivos:
bash mount -o compress=zlib,subvol=SubVol,autodefrag /dev/sdx /mnt
Lista os discos formatados no diretório:
bash btrfs filesystem show /mnt
Adiciona novo disco ao subvolume:
bash btrfs device add -f /dev/sdy /mnt
Lista novamente os discos do subvolume:
bash btrfs filesystem show /mnt
Exibe uso dos discos do subvolume:
bash btrfs filesystem df /mnt
Balancea os dados entre os discos sobre raid1:
bash btrfs filesystem balance start -dconvert=raid1 -mconvert=raid1 /mnt
Scrub é uma passagem por todos os dados e metadados do sistema de arquivos e verifica as somas de verificação. Se uma cópia válida estiver disponível (perfis de grupo de blocos replicados), a danificada será reparada. Todas as cópias dos perfis replicados são validadas.
iniciar o processo de depuração :
bash btrfs scrub start /mnt
ver o status do processo de depuração Btrfs em execução:
bash btrfs scrub status /mnt
ver o status do scrub Btrfs para cada um dos dispositivos
bash btrfs scrub status -d / data btrfs scrub cancel / data
Para retomar o processo de depuração do Btrfs que você cancelou ou pausou:
btrfs scrub resume / data
Listando os subvolumes:
bash btrfs subvolume list /Reports
Criando um instantâneo dos subvolumes:
Aqui, estamos criando um instantâneo de leitura e gravação chamado snap de marketing do subvolume de marketing.
bash btrfs subvolume snapshot /Reports/marketing /Reports/marketing-snap
Além disso, você pode criar um instantâneo somente leitura usando o sinalizador -r conforme mostrado. O marketing-rosnap é um instantâneo somente leitura do subvolume de marketing
bash btrfs subvolume snapshot -r /Reports/marketing /Reports/marketing-rosnap
Forçar a sincronização do sistema de arquivos usando o utilitário 'sync'
Para forçar a sincronização do sistema de arquivos, invoque a opção de sincronização conforme mostrado. Observe que o sistema de arquivos já deve estar montado para que o processo de sincronização continue com sucesso.
bash btrfs filsystem sync /Reports
Para excluir o dispositivo do sistema de arquivos, use o comando device delete conforme mostrado.
bash btrfs device delete /dev/sdc /Reports
Para sondar o status de um scrub, use o comando scrub status com a opção -dR .
bash btrfs scrub status -dR / Relatórios
Para cancelar a execução do scrub, use o comando scrub cancel .
bash $ sudo btrfs scrub cancel / Reports
Para retomar ou continuar com uma depuração interrompida anteriormente, execute o comando de cancelamento de depuração
bash sudo btrfs scrub resume /Reports
mostra o uso do dispositivo de armazenamento:
btrfs filesystem usage /data
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 .

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.

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

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

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

2025-05-10 03:55:38El insigne mendocino Juan Fernando Segovia falleció en el día de la festividad de Nuestra Señora de Luján, fecha significativa no sólo por ser la Patrona ríoplatense, sino además, anecdóticamente, porque cuando conocimos al profesor en tierras mejicanas tlaxcaltecas, escuchando la Santa Misa en la catedral (oficiada por el P. José Ramón García Gallardo); en un altar lateral coronandolo se encuentra una imágen de la Virgen muy parecida a la advocación, al hacerlo notar al profesor, la contempló sonriente y con mucha Fe. Este breve hecho significativo, sin duda fundamentó la labor abierta de Juan Fernando Segovia de ser fiel apóstol intelectual por los pueblos hispánicos, pues no sólo vino a compartir su sabiduría política, jurídica y moral, además de su genial convivencia con los asistentes en una, sino en las tres ediciones de las Conversaciones de la Ciudad Católica de Tlaxcala, haciendo notar la sinrazón de la cerrazón propia del nacionalismo (sin importar el apellido que le acompañe). Los Círculos Tradicionalistas de toda la Nueva España (cuyos buenos frutos son en gran parte obra de la labor incansable, conferencias presenciales y virtuales, libros y artículos de revistas para la conformación y formación continua de sus miembros), lamenta el vacío por la partida del maestro Juan Fernando Segovia.
Que Cristo Rey, a quien fielmente sirvió durante su vida, le dé el descanso eterno.

2025-05-10 00:57:52Recentemente, o podcast Scicast apresentou um episódio sobre aposentadoria, descrevendo os diferentes sistemas e sua história. Acho que, embora tenha sido um episódio interessante, foi muito injusto com o sistema de financiamento privado, que, afinal de contas, para um podcast voltado para a ciência (e que mencionou várias vezes que o sistema de repartição era matematicamente inviável), achei que alguns pontos precisavam ser esclarecidos.
Não estou dizendo que o sistema chileno é perfeito, não é, mas ele tinha potencial para melhorar e a classe política só o tornou cada vez pior.
Por exemplo, Otto von Bismarck sabia que tornaria a população idosa (os poucos que atingiram a idade de aposentadoria) dependente do Estado, e foi isso que fez com que Franco adotasse o sistema na Espanha, onde hoje é preciso aumentar os impostos para manter artificialmente o sistema de repartição.
A rentabilidade é baixa no sistema chileno, porque há lacunas (meses sem pagar) e porque você só contribui com 10%. Ou seja, se seu salário for 100, mas você contribuir com 10 em janeiro e mais nenhum mês. No final da sua vida profissional (45 anos) você terá 450 mais os rendimentos 1350, e esse total dividido pela expectativa de vida que está cada vez mais alta: 20 anos (24 meses) dá um salário de 56,25. Muito baixo, porque para o cálculo o salário era 100. Ainda mais baixo se a inflação for levada em conta. Mas o fato de haver meses sem contribuições não é levado em conta.
Deve-se considerar na rentabilidade que, em média, para cada 1 peso contribuído, são obtidos 3 pesos.Según cálculos de comissões
Várias comissões foram criadas para estudar como melhorar o sistema no Chile, e todas concluem a mesma coisa:
1- contribuir com 10% é muito baixo em comparação com outros sistemas
2- não se deve tolerar lacunas (a idade de aposentadoria não deve ser a idade natural, mas os anos de contribuição)
3- deve haver ajustes para cada aumento na expectativa de vida.
Esses três pontos acima não são tocados pelos políticos, porque são impopulares e eles vivem para a próxima eleição. Assim, eles preferem buscar outras formas, como o PGU (o salário básico universal que você já mencionou no podcast), que matematicamente já foi calculado como inviável no longo prazo.
Considere que 10% é baixo, mas ainda assim o Chile está muito bem classificado e poderia melhorar se os políticos tivessem a coragem de assumir os resultados das comissões que eles mesmos solicitaram.
https://www.65ymas.com/economia/pensiones/10-paises-con-mejores-sistemas-pensiones_22627_102.html
Foi mencionada a complexidade dos investimentos, o que é um mito, pois há fundos em que as contribuições são feitas de acordo com a idade do trabalhador (Fundo A para jovens, mais rentável, mas mais arriscado, e Fundo E, menos rentável, mas também menos arriscado). Na crise, as pessoas que perderam muito dinheiro foram porque estavam em um fundo que não correspondia à sua idade. Se você for jovem, poderá recuperar os retornos em um fundo de risco. Mas se for idoso na época da crise e não estiver em um fundo estável, já terá perdido sem poder se recuperar antes dos 65 anos.
Além disso, não se considera que há também um fundo voluntário adicional para o qual cada pessoa pode contribuir (APV), que tem benefícios como contribuições anuais do Estado para recompensar aqueles que contribuem para ele, e que também paga retornos.
Por outro lado, foi possível retirar dinheiro dos fundos individuais durante a crise pandêmica, algo que seria impossível em um fundo de repartição em que cada unidade monetária depositada por um trabalhador ativo é gasta ao mesmo tempo por um aposentado.
O modelo de repartição militar no Chile exige 20 anos de contribuições sem intervalos, qualquer intervalo e a pensão é de US$ 0, algo que não acontece no sistema civil (e não poderia acontecer porque o dinheiro lá é seu).
O sistema de capitalização individual no Chile permite que os trabalhadores possuam ativos de investimento, ativos de empresas que ajudaram o país a se desenvolver, algo que os políticos que querem derrubar o sistema parecem não entender.
E quanto à inflação? Investir em ativos que geram renda é útil tanto para mitigar a inflação quanto para ser proprietário, e esse último aspecto será relevante quando a automação chegar. Em vez de manter um registro artificial de quanto um robô produz, é mais transparente lucrar com os dividendos produzidos pela empresa em questão.
O sistema nórdico foi mencionado (que, afinal de contas, é praticamente o único sistema europeu que não está à beira do colapso). Vale a pena considerar que o dinheiro que a Noruega ganha com o petróleo vai para um fundo de investimento semelhante ao que temos individualmente no Chile, e a partir dele é paga grande parte do estado de bem-estar social norueguês. Mas isso é algo que parece muito distante, com a classe política latino-americana mais inclinada a desperdiçá-lo em bobagens populistas.
O modelo de distribuição é piramidal, embora possa parecer uma narrativa perigosa, é bom que as pessoas o vejam dessa forma (se um cidadão tirasse dinheiro dos jovens para dar aos idosos, provavelmente acabaria preso por um esquema ponzi), e a taxa de natalidade cada vez menor é um problema que o Estado não pode resolver, por mais totalitário que seja (estímulos fiscais e monetários etc. foram tentados com resultados ruins e míopes).
Além disso, por mais demonizado que seja na narrativa, o sistema chileno é um sistema misto com um pilar de solidariedade para aqueles que não contribuíram bem.
Na Argentina, passou-se da capitalização individual para o sistema de repartição, e o dinheiro foi usado pelos políticos quando não podiam pagar a conta de um Estado cada vez maior e corrupto, deixando os aposentados à mercê das migalhas dadas pelos políticos em cada campanha eleitoral. Você não confia no mercado, eu não confio no Estado.

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.

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

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

2025-05-09 23:10:14I. Historical Foundations of U.S. Monetary Architecture
The early monetary system of the United States was built atop inherited commodity money conventions from Europe’s maritime economies. Silver and gold coins—primarily Spanish pieces of eight, Dutch guilders, and other foreign specie—formed the basis of colonial commerce. These units were already integrated into international trade and piracy networks and functioned with natural compatibility across England, France, Spain, and Denmark. Lacking a centralized mint or formal currency, the U.S. adopted these forms de facto.
As security risks and the practical constraints of physical coinage mounted, banks emerged to warehouse specie and issue redeemable certificates. These certificates evolved into fiduciary media—claims on specie not actually in hand. Banks observed over time that substantial portions of reserves remained unclaimed for years. This enabled fractional reserve banking: issuing more claims than reserves held, so long as redemption demand stayed low. The practice was inherently unstable, prone to panics and bank runs, prompting eventual centralization through the formation of the Federal Reserve in 1913.
Following the Civil War and unstable reinstatements of gold convertibility, the U.S. sought global monetary stability. After World War II, the Bretton Woods system formalized the U.S. dollar as the global reserve currency. The dollar was nominally backed by gold, but most international dollars were held offshore and recycled into U.S. Treasuries. The Nixon Shock of 1971 eliminated the gold peg, converting the dollar into pure fiat. Yet offshore dollar demand remained, sustained by oil trade mandates and the unique role of Treasuries as global reserve assets.
II. The Structure of Fiduciary Media and Treasury Demand
Under this system, foreign trade surpluses with the U.S. generate excess dollars. These surplus dollars are parked in U.S. Treasuries, thereby recycling trade imbalances into U.S. fiscal liquidity. While technically loans to the U.S. government, these purchases act like interest-only transfers—governments receive yield, and the U.S. receives spendable liquidity without principal repayment due in the short term. Debt is perpetually rolled over, rarely extinguished.
This creates an illusion of global subsidy: U.S. deficits are financed via foreign capital inflows that, in practice, function more like financial tribute systems than conventional debt markets. The underlying asset—U.S. Treasury debt—functions as the base reserve asset of the dollar system, replacing gold in post-Bretton Woods monetary logic.
III. Emergence of Tether and the Parastatal Dollar
Tether (USDT), as a private issuer of dollar-denominated tokens, mimics key central bank behaviors while operating outside the regulatory perimeter. It mints tokens allegedly backed 1:1 by U.S. dollars or dollar-denominated securities (mostly Treasuries). These tokens circulate globally, often in jurisdictions with limited banking access, and increasingly serve as synthetic dollar substitutes.
If USDT gains dominance as the preferred medium of exchange—due to technological advantages, speed, programmability, or access—it displaces Federal Reserve Notes (FRNs) not through devaluation, but through functional obsolescence. Gresham’s Law inverts: good money (more liquid, programmable, globally transferable USDT) displaces bad (FRNs) even if both maintain a nominal 1:1 parity.
Over time, this preference translates to a systemic demand shift. Actors increasingly use Tether instead of FRNs, especially in global commerce, digital marketplaces, or decentralized finance. Tether tokens effectively become shadow base money.
IV. Interaction with Commercial Banking and Redemption Mechanics
Under traditional fractional reserve systems, commercial banks issue loans denominated in U.S. dollars, expanding the money supply. When borrowers repay loans, this destroys the created dollars and contracts monetary elasticity. If borrowers repay in USDT instead of FRNs:
- Banks receive a non-Fed liability (USDT).
- USDT is not recognized as reserve-eligible within the Federal Reserve System.
- Banks must either redeem USDT for FRNs, or demand par-value conversion from Tether to settle reserve requirements and balance their books.
This places redemption pressure on Tether and threatens its 1:1 peg under stress. If redemption latency, friction, or cost arises, USDT’s equivalence to FRNs is compromised. Conversely, if banks are permitted or compelled to hold USDT as reserve or regulatory capital, Tether becomes a de facto reserve issuer.
In this scenario, banks may begin demanding loans in USDT, mirroring borrower behavior. For this to occur sustainably, banks must secure Tether liquidity. This creates two options: - Purchase USDT from Tether or on the secondary market, collateralized by existing fiat. - Borrow USDT directly from Tether, using bank-issued debt as collateral.
The latter mirrors Federal Reserve discount window operations. Tether becomes a lender of first resort, providing monetary elasticity to the banking system by creating new tokens against promissory assets—exactly how central banks function.
V. Structural Consequences: Parallel Central Banking
If Tether begins lending to commercial banks, issuing tokens backed by bank notes or collateralized debt obligations: - Tether controls the expansion of broad money through credit issuance. - Its balance sheet mimics a central bank, with Treasuries and bank debt as assets and tokens as liabilities. - It intermediates between sovereign debt and global liquidity demand, replacing the Federal Reserve’s open market operations with its own issuance-redemption cycles.
Simultaneously, if Tether purchases U.S. Treasuries with FRNs received through token issuance, it: - Supplies the Treasury with new liquidity (via bond purchases). - Collects yield on government debt. - Issues a parallel form of U.S. dollars that never require redemption—an interest-only loan to the U.S. government from a non-sovereign entity.
In this context, Tether performs monetary functions of both a central bank and a sovereign wealth fund, without political accountability or regulatory transparency.
VI. Endgame: Institutional Inversion and Fed Redundancy
This paradigm represents an institutional inversion:
- The Federal Reserve becomes a legacy issuer.
- Tether becomes the operational base money provider in both retail and interbank contexts.
- Treasuries remain the foundational reserve asset, but access to them is mediated by a private intermediary.
- The dollar persists, but its issuer changes. The State becomes a fiscal agent of a decentralized financial ecosystem, not its monetary sovereign.
Unless the Federal Reserve reasserts control—either by absorbing Tether, outlawing its instruments, or integrating its tokens into the reserve framework—it risks becoming irrelevant in the daily function of money.
Tether, in this configuration, is no longer a derivative of the dollar—it is the dollar, just one level removed from sovereign control. The future of monetary sovereignty under such a regime is post-national and platform-mediated.

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

@ 0fa80bd3:ea7325de
2025-01-29 05:55:02The land that belongs to the indigenous peoples of Russia has been seized by a gang of killers who have unleashed a war of extermination. They wipe out anyone who refuses to conform to their rules. Those who disagree and stay behind are tortured and killed in prisons and labor camps. Those who flee lose their homeland, dissolve into foreign cultures, and fade away. And those who stand up to protect their people are attacked by the misled and deceived. The deceived die for the unchecked greed of a single dictator—thousands from both sides, people who just wanted to live, raise their kids, and build a future.
Now, they are forced to make an impossible choice: abandon their homeland or die. Some perish on the battlefield, others lose themselves in exile, stripped of their identity, scattered in a world that isn’t theirs.
There’s been endless debate about how to fix this, how to clear the field of the weeds that choke out every new sprout, every attempt at change. But the real problem? We can’t play by their rules. We can’t speak their language or use their weapons. We stand for humanity, and no matter how righteous our cause, we will not multiply suffering. Victory doesn’t come from matching the enemy—it comes from staying ahead, from using tools they haven’t mastered yet. That’s how wars are won.
Our only resource is the will of the people to rewrite the order of things. Historian Timothy Snyder once said that a nation cannot exist without a city. A city is where the most active part of a nation thrives. But the cities are occupied. The streets are watched. Gatherings are impossible. They control the money. They control the mail. They control the media. And any dissent is crushed before it can take root.
So I started asking myself: How do we stop this fragmentation? How do we create a space where people can rebuild their connections when they’re ready? How do we build a self-sustaining network, where everyone contributes and benefits proportionally, while keeping their freedom to leave intact? And more importantly—how do we make it spread, even in occupied territory?
In 2009, something historic happened: the internet got its own money. Thanks to Satoshi Nakamoto, the world took a massive leap forward. Bitcoin and decentralized ledgers shattered the idea that money must be controlled by the state. Now, to move or store value, all you need is an address and a key. A tiny string of text, easy to carry, impossible to seize.
That was the year money broke free. The state lost its grip. Its biggest weapon—physical currency—became irrelevant. Money became purely digital.
The internet was already a sanctuary for information, a place where people could connect and organize. But with Bitcoin, it evolved. Now, value itself could flow freely, beyond the reach of authorities.
Think about it: when seedlings are grown in controlled environments before being planted outside, they get stronger, survive longer, and bear fruit faster. That’s how we handle crops in harsh climates—nurture them until they’re ready for the wild.
Now, picture the internet as that controlled environment for ideas. Bitcoin? It’s the fertile soil that lets them grow. A testing ground for new models of interaction, where concepts can take root before they move into the real world. If nation-states are a battlefield, locked in a brutal war for territory, the internet is boundless. It can absorb any number of ideas, any number of people, and it doesn’t run out of space.
But for this ecosystem to thrive, people need safe ways to communicate, to share ideas, to build something real—without surveillance, without censorship, without the constant fear of being erased.
This is where Nostr comes in.
Nostr—"Notes and Other Stuff Transmitted by Relays"—is more than just a messaging protocol. It’s a new kind of city. One that no dictator can seize, no corporation can own, no government can shut down.
It’s built on decentralization, encryption, and individual control. Messages don’t pass through central servers—they are relayed through independent nodes, and users choose which ones to trust. There’s no master switch to shut it all down. Every person owns their identity, their data, their connections. And no one—no state, no tech giant, no algorithm—can silence them.
In a world where cities fall and governments fail, Nostr is a city that cannot be occupied. A place for ideas, for networks, for freedom. A city that grows stronger the more people build within it.

2025-05-06 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.

2025-01-18 06:09:50Para esse exemplo iremos usar: | Nome | Imagem | Descrição | | --------------- | ------------------------------------------------------------ | ------------------------------------------------------------ | | Raspberry PI B+ |
| Cortex-A53 (ARMv8) 64-bit a 1.4GHz e 1 GB de SDRAM LPDDR2, | | Pen drive |
| 16Gb |
Recomendo que use o Ubuntu Server para essa instalação. Você pode baixar o Ubuntu para Raspberry Pi aqui. O passo a passo para a instalação do Ubuntu no Raspberry Pi está disponível aqui. Não instale um desktop (como xubuntu, lubuntu, xfce, etc.).
Passo 1: Atualizar o Sistema 🖥️
Primeiro, atualize seu sistema e instale o Tor:
bash apt update apt install tor
Passo 2: Criar o Arquivo de Serviço
nrs.service
🔧Crie o arquivo de serviço que vai gerenciar o servidor Nostr. Você pode fazer isso com o seguinte conteúdo:
```unit [Unit] Description=Nostr Relay Server Service After=network.target
[Service] Type=simple WorkingDirectory=/opt/nrs ExecStart=/opt/nrs/nrs-arm64 Restart=on-failure
[Install] WantedBy=multi-user.target ```
Passo 3: Baixar o Binário do Nostr 🚀
Baixe o binário mais recente do Nostr aqui no GitHub.
Passo 4: Criar as Pastas Necessárias 📂
Agora, crie as pastas para o aplicativo e o pendrive:
bash mkdir -p /opt/nrs /mnt/edriver
Passo 5: Listar os Dispositivos Conectados 🔌
Para saber qual dispositivo você vai usar, liste todos os dispositivos conectados:
bash lsblk
Passo 6: Formatando o Pendrive 💾
Escolha o pendrive correto (por exemplo,
/dev/sda
) e formate-o:bash mkfs.vfat /dev/sda
Passo 7: Montar o Pendrive 💻
Monte o pendrive na pasta
/mnt/edriver
:bash mount /dev/sda /mnt/edriver
Passo 8: Verificar UUID dos Dispositivos 📋
Para garantir que o sistema monte o pendrive automaticamente, liste os UUID dos dispositivos conectados:
bash blkid
Passo 9: Alterar o
fstab
para Montar o Pendrive Automáticamente 📝Abra o arquivo
/etc/fstab
e adicione uma linha para o pendrive, com o UUID que você obteve no passo anterior. A linha deve ficar assim:fstab UUID=9c9008f8-f852 /mnt/edriver vfat defaults 0 0
Passo 10: Copiar o Binário para a Pasta Correta 📥
Agora, copie o binário baixado para a pasta
/opt/nrs
:bash cp nrs-arm64 /opt/nrs
Passo 11: Criar o Arquivo de Configuração 🛠️
Crie o arquivo de configuração com o seguinte conteúdo e salve-o em
/opt/nrs/config.yaml
:yaml app_env: production info: name: Nostr Relay Server description: Nostr Relay Server pub_key: "" contact: "" url: http://localhost:3334 icon: https://external-content.duckduckgo.com/iu/?u= https://public.bnbstatic.com/image/cms/crawler/COINCU_NEWS/image-495-1024x569.png base_path: /mnt/edriver negentropy: true
Passo 12: Copiar o Serviço para o Diretório de Systemd ⚙️
Agora, copie o arquivo
nrs.service
para o diretório/etc/systemd/system/
:bash cp nrs.service /etc/systemd/system/
Recarregue os serviços e inicie o serviço
nrs
:bash systemctl daemon-reload systemctl enable --now nrs.service
Passo 13: Configurar o Tor 🌐
Abra o arquivo de configuração do Tor
/var/lib/tor/torrc
e adicione a seguinte linha:torrc HiddenServiceDir /var/lib/tor/nostr_server/ HiddenServicePort 80 127.0.0.1:3334
Passo 14: Habilitar e Iniciar o Tor 🧅
Agora, ative e inicie o serviço Tor:
bash systemctl enable --now tor.service
O Tor irá gerar um endereço
.onion
para o seu servidor Nostr. Você pode encontrá-lo no arquivo/var/lib/tor/nostr_server/hostname
.
Observações ⚠️
- Com essa configuração, os dados serão salvos no pendrive, enquanto o binário ficará no cartão SD do Raspberry Pi.
- O endereço
.onion
do seu servidor Nostr será algo como:ws://y3t5t5wgwjif<exemplo>h42zy7ih6iwbyd.onion
.
Agora, seu servidor Nostr deve estar configurado e funcionando com Tor! 🥳

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

2025-05-06 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.

2025-05-09 22:54:43The global financial system is creaking under its own weight. The IMF is urging banks to shore up capital, cut risk, and brace for impact. Basel III is their answer, a last-ditch effort to reinforce a brittle foundation.
But behind the scenes, a quieter revolution is under way.
Bitcoin, the world’s first stateless digital asset, is no longer on the sidelines. It’s entering the Basel conversation: not by invitation, but by inevitability.
Basel III: The System’s Self-Diagnosis
Basel III is more than a technical rulebook. It’s a confession: an admission that the global banking system is vulnerable. Created in the aftermath of 2008, it calls for: • Stronger capital reserves: So banks can survive losses. • Lower leverage: To reduce the domino effect of overexposure. • Liquidity buffers: To weather short-term shocks without collapsing.
But here’s the kicker: these rules are hostile to anything outside the fiat system. Bitcoin gets hit with a punitive 1,250% risk weight. That means for every $1 of exposure, banks must hold $1 in capital. The message from regulators? “You can hold Bitcoin, but you’ll pay for it.”
Yet that fear: based framing misses a bigger truth: Bitcoin doesn’t just survive in this environment. It thrives in it.
Bitcoin: A Parallel System, Built on Hard Rules
Where Basel III imposes “fiat discipline” from the top down, Bitcoin enforces it from the bottom up: with code, math, and transparency.
Bitcoin is not just a hedge. It’s a structural antidote to systemic fragility.
Volatility: A Strategic Asset
Yes, Bitcoin is volatile. But in a system that devalues fiat on a schedule, volatility is simply the cost of freedom. Under Basel III, banks are expected to build capital buffers during economic expansions.
What asset allows you to build those buffers faster than Bitcoin in a bull market?
When the cycle turns, those reserves act as shock absorbers: converting volatility into resilience. It’s anti-fragility in motion.
Liquidity: Real, Deep, and Global
Bitcoin settled over $19 trillion in transactions in 2024. That’s not hypothetical liquidity. it’s real, measurable flow. Unlike traditional high-quality liquid assets (HQLAs), Bitcoin is: • Available 24/7 • Borderless • Not dependent on central banks
By traditional definitions, Bitcoin is rapidly qualifying for HQLA status. Even if regulators aren’t ready to admit it.
Diversification: Breaking the Fiat Dependency
Basel III is designed to pull banks back into the fiat matrix. But Bitcoin offers an escape hatch. Strategic Bitcoin reserves are not about speculation, they’re insurance. For family offices, institutions, and sovereign funds, Bitcoin is the lifeboat when the fiat ship starts taking on water.
Regulatory Realignment: The System Reacts
The Basel Committee’s new rules on crypto exposures went live in January 2025. Around the world, regulators are scrambling to define their stance. Every new restriction placed on Bitcoin only strengthens its legitimacy, as more institutions ask: Why so much resistance, if it’s not a threat?
Bitcoin doesn’t need permission. It’s already being adopted by over 150 public companies, forward-looking states, and a new class of self-sovereign individuals.
Conclusion: The Real Question
This isn’t just about Bitcoin fitting into Basel III.
The real question is: How long can Basel III remain relevant in a world where Bitcoin exists?
Bitcoin is not the risk. It’s the reality check. And it might just be the strongest capital buffer the system has ever seen.
Gradually then suddenly.

@ d61f3bc5:0da6ef4a
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! 🌸
