2025-05-29 16:23:24I’ve got this little crew of friends, and somehow, I ended up as the baby of the group. I’m 18, and my buddies are 23, 19, and 25. It’s kinda funny when you think about it — I’m the youngest by a solid margin, but it’s never felt like a big deal. Honestly, being around older guys has taught me something: males don’t really care about age the way people might think.
When we hang out, it’s not like they’re sitting there calculating birth years or treating me like some kid who wandered into the wrong room. We’re just vibing — playing video games, grabbing food, or talking about whatever’s on our minds. Sure, the 25-year-old might have a bit more life experience, like stories about his first job or some wild trip he took, but it’s not a hierarchy thing. He’s not preaching; he’s just sharing. And me? I’m soaking it all up, probably growing up faster than I would’ve otherwise. The 23-year-old’s always got these random facts he drops like he’s some walking encyclopedia, and the 19-year-old is basically my partner-in-crime for dumb ideas. Age gaps? Barely notice ‘em. I think it’s because, as guys, we’re more about what’s happening right now than some number tied to when we were born. Like, who cares if I wasn’t around for some movie they all saw in middle school? We’re watching stuff together now, and that’s what counts.
Sometimes I wonder if it’d be different with girls — maybe they’d care more about the age thing, I don’t know. But with my crew, it’s chill. I’m 18, they’re older, and it’s just… us. No one’s keeping score. Maybe that’s the secret: age is just a number when you’re all on the same wavelength.

2025-05-29 16:20:45In the whirlwind of life, where we’re constantly bombarded by expectations, responsibilities, and the relentless ticking of the clock, it’s easy to lose sight of who we truly are. Are we merely boys masquerading as men, or have we embraced the mantle of manhood in its truest form? This question isn’t about age; it’s about essence, about purpose.
I stumbled upon this video the other day, titled "Are you a Man who’s a Boy, or a Boy who’s a Man?" by motivational speaker Les Brown. In it, he hits you with a truth bomb that echoes in your soul: Most people, they go to their graves with their greatness still in them." This sentence, simple yet profound, struck a chord with me. How often do we let fear, doubt, or the comfort of the known keep us from exploring our true potential? Watching that video, I couldn’t help but reflect on my own journey. I remember being in my early twenties, feeling like a boy in a man’s world. I was unsure, hesitant, and frankly, scared of what life might ask of me. But one day, after a particularly tough week, I watched this video, and something clicked. Les Brown’s passionate delivery made me realize that purpose isn’t something you find; it’s something you forge through the trials and tribulations of life. Here’s the deal: your purpose isn’t handed to you on a silver platter. It’s discovered through the grind, the hustle, the moments when you’re ready to throw in the towel but decide to keep going. Like when I switched careers, moving from a stable job to chasing a dream that felt more like me. It was terrifying, but it was in that leap of faith where I found my purpose - to inspire others to live their truth, no matter how daunting it seems. So, what’s your purpose in life?Are you still figuring it out, or are you out there living it? If you’re feeling lost, remember, it’s okay. We’re all works in progress. But don’t let that become an excuse to stay stationary. Push yourself, challenge the comfort zone, because as Les Brown so candidly puts it,
"You have greatness within you."
And here’s a little wisdom from my own life: purpose isn’t just about what you do; it’s about how you live every single day. It’s in the small acts of kindness, in standing up for what you believe in, in the relentless pursuit of becoming a better version of yourself. So, are you a man who’s a boy, still caught up in the games and fears of youth? Or are you a boy who’s stepping up to be a man, ready to claim your purpose?
Let’s not go to our graves with our greatness still inside us. Let’s live it, loud and proud, with all the courage of a boy who knows he’s becoming a man. Remember, life's too short for regrets, too precious to not live your purpose. Here's to finding it, or better yet, making it. Keep pushing, keep growing. And hey, if all else fails, at least you've got the wisdom of Les Brown and a friend in me to help you navigate this wild ride called life. 🌟 "Most people, they go to their graves with their greatness still in them." - Les Brown.

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

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

2025-05-29 16:15:13Life is full of ups and downs, uncertainties and challenges. But one of the most things life has is it ability to demand. It’s doesn’t care wether you’re sick, old, young, man or women. You must have something to offer .
I remember vividly what happened to me last year. It was time to resume school and my pops doesn’t have my tuition fee. So I decided to hustle for it by myself. I thought it’ll be easy, thinking I can get the money before the period of 1 month. I had my plans, but It seems like life has it own plans as well. I started doing some online businesses thinking it’s going to be alright. But then, all the things I engage myself in wasn’t going as planned. All my investments were gone, back to having a dry account and empty pockets. It was at that time I figured, life is playing with me. I nearly run mad during that period cause there was no one out there to help me go through this hardship. But then I remembered something that made me stopped over thinking. “You don’t know what tomorrow yield, you can die tonight and then everything will be useless” I keep this thought in my head. Why all the struggle for a life that you aren’t promised of tomorrow. We all sleep with the intentions of waking up the next day and continuing our lifestyle. But some of us don’t get to see tomorrow This thought made me think, I shouldn’t carry the weight of the world around my neck. It’s all useless if you die. There’s no point of all this struggle. This made me relieve the pressure I had on myself. And made me focus more on what am doing now instead of thinking of what’s going to happen in the future.
We should leave that aspect to GOD. A little advice to those young folks reading this. Don’t pressure yourself, what is meant for you will always be yours. And always have faith in GOD, he’s plans are better than yours. Life is hard and cruel, but when you decide to go with the thought that you alone can’t handle it all. That’s why GOD is there to handle our hidden battles for us.

GameStop CEO Ryan Cohen Announced Acquisition of Over $505 Million BitcoinAt the 2025 Bitcoin Conference in Las Vegas, in an interview with the CEO of Nakamoto David Bailey, the CEO of GameStop Ryan Cohen announced why the company bought over $505 million in Bitcoin.
JUST IN: GameStop $GME CEO explains why the company bought over $505 million #Bitcoin
“Bitcoin can be a hedge against global currency devaluation” pic.twitter.com/jNiId2fntA
— Bitcoin Magazine (@BitcoinMagazine) May 28, 2025
Ryan Cohen started by explaining some things about the GameStop business.
“When I took over, the company was a piece of crap and losing a lot of money and was under a lot of pressure moving from physical gains to digital downloads so you had to cut costs,” stated Cohen. “Very aggressively bringing physical discipline and we did. Retail is a tough business, but it was a big focus on getting cost under control.”
When Bailey asked Cohen how many Bitcoin GameStop owned, Ryan responded, “We currently own 4710 Bitcoin.”
Then Ryan mentioned why they are adding Bitcoin to their balance sheets.
“If the thesis is correct then Bitcoin and gold as well can be a hedge against global currency devaluation and systemic risk,” mentioned Ryan. “Bitcoin has certain unique advantages better than gold.”
He commented on the benefits of Bitcoin compared to gold.
“You can easily secure Bitcoin in a wallet whereas gold requires insurance and it’s very expensive and then there is the scarcity element of this as well,” commented Ryan. “There is a fixed supply of Bitcoin whereas with gold, the supply of gold is still uncertain.“
Ryan finished the announcement by saying, “GameStop is following GameStop Strategy. We are not following anyone else’s.”

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

2025-05-29 15:52:45Bulgária: Először töltenek be Westinghouse-üzemanyagot a Kozloduy-5-be
Először töltöttek be Westinghouse által gyártott nukleáris üzemanyag-kazettákat Bulgária Kozloduy-5 VVER-1000 reaktorába 2025. május 29-én. Ez jelentős lépés Szófia azon törekvésében, hogy csökkentse orosz nukleáris üzemanyag-függőségét, és diverzifikálja energiaforrásait. A lépés része annak a szélesebb stratégiának, amelynek célja az energiaellátás biztonságának növelése és a nyugati partnerekkel való szorosabb együttműködés[NucNet].
Fehér Ház: Nukleáris Telepítési Csúcstalálkozó az USA-ban
A mai napon a Fehér Ház Nukleáris Telepítési Csúcstalálkozót tartott, amelyen kiemelték a köz- és magánszféra eredményeit. Fő témák voltak az orosz urántól való amerikai függőség csökkentése, a nukleáris üzemanyag-ellátási lánc bővítése, valamint a globális nukleáris kapacitás 2050-ig történő megháromszorozásának támogatása. A csúcson szó esett a nagy nukleáris projektek kockázatainak csökkentéséről, új reaktortervezetekről és a meglévő atomerőművek élettartamának meghosszabbításáról is. Az amerikai kormány hangsúlyozta, hogy továbbra is támogatja a fejlett nukleáris demonstrációs projekteket, a munkaerő-fejlesztést, valamint a legújabb törvényhozási lépéseket, például az orosz uránimport tilalmáról szóló törvényt[World Nuclear News].
Törékeny áramellátás a zaporizzsjai atomerőműben, Ukrajna
Az IAEA jelentése szerint az ukrajnai Zaporizzsjai Atomerőmű továbbra is rendkívül sebezhető helyzetben van, mivel jelenleg csak egyetlen külső áramvezetékre támaszkodik a biztonsági rendszerek működtetéséhez. Az utolsó tartalék vezeték három hete le van választva, ami aggodalomra ad okot a hűtő- és biztonsági rendszerek stabilitását illetően. Bár a létesítmény három éve nem termel áramot, folyamatos elektromos ellátásra van szükség a kiégett fűtőelemek hűtéséhez. Az IAEA továbbra is szorosan figyelemmel kíséri a helyzetet, és kiemeli a régióban zajló katonai tevékenységet[IAEA].
USA: SMR-fejlesztések és költségvetési megszorítások
A Tennessee Valley Authority benyújtotta az építési engedélykérelmet egy GE Vernova Hitachi BWRX-300 típusú kis moduláris reaktor (SMR) telepítésére a Clinch River helyszínen, ami jelentős előrelépés az amerikai SMR-programban. Eközben az amerikai kormány 2026-os költségvetési tervezete jelentős csökkentéseket irányoz elő az Energiaügyi Minisztérium nukleáris finanszírozásában, különösen a nem elsődleges kutatási területeken. A fókusz az innovatív reaktorkoncepciókra, fejlett üzemanyagokra és a kulcsfontosságú nemzeti laboratóriumi képességek fenntartására helyeződik[World Nuclear News][World Nuclear News].
Savannah River Site: Előrelépés a plutónium-magházak gyártásában
Az amerikai Energiaügyi Minisztérium Savannah River telephelyén megkezdődött a kesztyűs dobozok gyártása a plutónium magházak előállításához. Ezek a kesztyűs dobozok kulcsfontosságúak a Savannah River Plutonium Processing Facility számára, amely a Nemzeti Nukleáris Biztonsági Igazgatóság célkitűzéseit támogatja, hogy a projektet a 2030-as évek elejéig befejezzék. Ez a lépés az amerikai nukleáris fegyverkezési infrastruktúra modernizációjának része[ANS].
Nemzetközi trendek: ellátási lánc és új reaktorprojektek
A nukleáris ellátási lánc a globális növekedésre készül, ahogy azt a World Nuclear Association legutóbbi konferenciáján is hangsúlyozták. Kiemelt nemzetközi fejlemények:
- Gőzturbina-hengerek telepítése Kína Haiyang 3 erőművében.
- Új, négy reaktoros telephely jóváhagyása Indiában, Rádzsasztánban.
- Belgium és Dánia újragondolja a nukleáris kivonulási politikáját.
- Brazília az oroszokkal való SMR-együttműködést vizsgálja.
- Kanada előrelép a szállítható nukleáris erőmű-technológia terén[World Nuclear News].
Érintetti bevonás és a nukleáris energia szerepe a tiszta átmenetben
Az IAEA konferenciasorozata továbbra is hangsúlyozza az érintetti bevonás fontosságát a nukleáris non-proliferáció, biztonság és a közbizalom szempontjából. A panelek foglalkoznak a közvélemény-tájékoztatás tanulságaival, a nukleáris energia ipari dekarbonizációban betöltött szerepével és az újonnan belépő országok nukleáris infrastruktúra-fejlesztési tapasztalataival is[IAEA].

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

2025-05-29 15:21:33What’s Happening in Japan? Japan has the highest debt-to-GDP ratio in the developed world — over 260%. For decades, it got away with this by keeping interest rates near zero and having the Bank of Japan (BoJ) purchase most of its government bonds. This was known as Yield Curve Control — a desperate attempt to keep borrowing costs low.
But now, global bond markets are revolting.
🔺 Japanese 30-year yields have exploded past 3.18%
🔺 The worst bond auction since 1987 just occurred
🔺 Demand for JGBs (Japanese Government Bonds) is collapsing
When demand for bonds falls, prices drop and yields rise. This signals fear. Big fear.
As Taylor Kenney noted in a widely shared thread:
“This isn’t just a Japan problem — Japan is the largest foreign holder of U.S. debt.” The Contagion Risk: U.S. Debt and Global Collapse
Here’s where this gets truly global.
In 2025 alone, $9.2 trillion of U.S. debt will mature — 70% of it between January and June. That debt must be refinanced, and as interest rates remain elevated, the cost of servicing this debt balloons, potentially straining the U.S. government’s finances.
If yields rise further, it only worsens the cycle:
-
Yields rise
-
Interest costs balloon
-
Governments print more to cover deficits
-
Currencies debase
-
Confidence dies
-
Collapse follows
Japan may just be the canary in the coal mine. Gold Is Surging. Bitcoin Is Outpacing It.
Smart money is already moving.
Bitcoin is closing in on its all-time high — and closely tracking the M2 Global Liquidity Index, historically lagging it by 60–90 days.
Gold has also had a stellar run in 2025, signalling institutional flight to hard assets.
People are scared. And they should be.
The global financial system is built on an unsustainable foundation of debt, inflation, and artificial suppression of interest rates. That system is now cracking in Japan — but it won’t stop there. ₿ Bitcoin: The Exit Plan
Bitcoin doesn’t rely on a central bank.
It doesn’t need to be refinanced.
It doesn’t have a yield curve to control.
It’s decentralised, scarce, and incorruptible.
While fiat currencies spiral under the weight of debt and monetary debasement, Bitcoin offers an escape — a monetary protocol with a fixed supply and no political manipulation.
It’s not just an investment.
It’s an exit strategy from the madness. Final Thoughts
-
Japan is flashing red.
-
The U.S. is next in line.
-
The debt system is spiralling — fast.
Gold is insurance.
Bitcoin is the lifeboat.

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

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

2025-05-29 15:19:56The Weimar Hyperinflation Nightmare
It’s 1921. Germany’s reeling from World War I, crushed by reparations and a wrecked economy. The government’s solution? Print money. Lots of it. The German mark starts tanking. By 1923, it’s a joke—4.2 trillion marks to one U.S. dollar. A loaf of bread costs wheelbarrows of cash. Savings? Wiped out. Middle-class families? Pauperized. Chaos.
Enter Hugo Stinnes, a coal and steel magnate with a sharp mind and sharper instincts. He sees the game: when a currency’s dying, debt is your friend. Why? Because the real value of your loans shrinks as inflation skyrockets. Borrow 1 million marks today, buy a factory, and by next year, that million’s worth a few pennies. Pay it back, keep the factory, repeat.
Stinnes’ Master Play
Stinnes goes all in. He borrows billions of marks, snapping up hard assets—steel mills, shipping lines, factories, real estate. Tangible stuff that holds value while paper marks turn to confetti. By 1923, his empire is a beast: over 1,500 companies, from coal mines to newspapers. Estimates say he controlled 15-20% of Germany’s industry, maybe more. A third of the economy? Probably an exaggeration, but the guy was a titan.
He wasn’t just lucky. Stinnes played 4D chess. He diversified his holdings to weather the storm, employed tens of thousands (keeping unrest at bay), and even argued his empire stabilized the economy. Critics, like British diplomat Lord D’Abernon, weren’t buying it—they called him a profiteer who thrived while others starved. Truth? Probably somewhere in the middle.
The Fall
Hyperinflation couldn’t last forever. In November 1923, Germany introduced the Rentenmark, a new currency backed by land and assets. The mark’s freefall stopped. Stinnes’ debt-fueled strategy hit a wall—stable currencies make loans harder to game. His health was failing too. He died in 1924, and his conglomerate started unraveling, with parts sold off or restructured. The Inflation King’s reign was over.
Why This Matters Today: Enter Bitcoin
Stinnes’ story isn’t just a history lesson—it’s a warning. Hyperinflation destroys trust in fiat money. When governments print cash to cover debts, savers get crushed, and the clever (or ruthless) like Stinnes exploit the chaos. Sound familiar? Look at today: global debt’s at $315 trillion, central banks are juggling interest rates, and inflation’s eating purchasing power. Argentina’s peso lost 50% of its value in 2024 alone. Venezuela’s bolívar? Toast.
This is where Bitcoin comes in. Born in 2009 after the financial crisis, Bitcoin is a hedge against fiat’s flaws. Unlike marks or dollars, it’s decentralised—no government can print more to pay its bills. Its supply is capped at 21 million coins, making it “digital gold.” When fiat currencies wobble, Bitcoin’s value often spikes—check its 2021 and 2024 bull runs during inflation fears.
Stinnes gamed a broken system by betting on hard assets. Today, Bitcoiners are doing the same, but instead of factories, they’re stacking sats. Why? Because in a world where fiat can be printed to oblivion, a deflationary asset like Bitcoin holds appeal. It’s not perfect—volatility’s a beast, and governments hate what they can’t control—but it’s a response to the same problem Stinnes faced: untrustworthy money.
The Lesson
Stinnes saw the Weimar collapse coming and turned it into wealth. Most didn’t. Today, you don’t need to be a tycoon to protect yourself, but you do need to understand the game. Fiat’s not collapsing tomorrow, but cracks are showing. Bitcoin’s one tool—maybe not the only one—to hedge against that risk. Study history, question the system, and don’t get caught holding the bag.

2025-05-29 15:17:06Bitcoin’s Path to Global Dominance: Store of Value, Medium of Exchange, and the Road to a Bitcoin Standard
Bitcoin has ignited a financial revolution, captivating everyone from tech enthusiasts to institutional investors. Yet, amidst its meteoric rise, a tantalising question emerges: Could Bitcoin become the world’s reserve currency, relegating fiat currencies to the history books? This vision—a global Bitcoin standard—stirs intense debate within the community. Some champion Bitcoin as a Store of Value (SOV), a digital equivalent to gold, while others insist its future lies in becoming a Medium of Exchange (MOE), used for everyday transactions. With conflicting perspectives and community members at varying points in their Bitcoin journey, it’s time to unpack these ideas and chart a unified course.
This article delves into the interplay between Bitcoin’s SOV and MOE roles, examines the hurdles to widespread adoption, and proposes a roadmap for Bitcoin to claim global reserve status. My goal is to ignite a vibrant discussion, bridge divides, and encourage the Bitcoin community to rally around a shared vision for the future.
The Building Blocks: What Are SOV and MOE?
To kick things off, let’s define the two pillars of this debate:
• Store of Value (SOV): An asset that holds or grows its worth over time, offering a dependable way to preserve wealth. Think gold, a classic example cherished for millennia.
• Medium of Exchange (MOE): A tool for transactions, enabling the seamless exchange of goods and services. Today, fiat currencies like the pound or dollar reign supreme in this domain.
Bitcoin’s allure stems from its unique traits: a capped supply of 21 million coins, a decentralised network, and immunity to censorship. These qualities position it as a contender to replace both gold and fiat money—but the journey is complex, and the community’s views are far from aligned.
Where We Stand: Bitcoin as Digital Gold
Bitcoin’s ascent has been propelled by its prowess as a Store of Value. Early adopters, savvy investors, and even big institutions have embraced it as a shield against inflation, economic turmoil, and the erosion of fiat value. Its scarcity—hardwired into its code—has cemented the “digital gold” narrative, drawing in those seeking a safe haven in uncertain times.
But here’s the rub: while Bitcoin shines as an SOV, it’s rarely used as an MOE. Its price swings, technical limitations, and patchy acceptance by merchants make it a tough sell for buying a pint or a loaf of bread. Many in the community—think of figures like Michael Saylor—preach the gospel of “hodling,” urging followers to stash Bitcoin away and watch its value soar. This strategy has paid off handsomely for some, but it begs a bigger question: Can Bitcoin rule the world if it remains a speculative treasure rather than a working currency?
The Adoption Puzzle: Bridging SOV and MOE
For Bitcoin to leap from a niche asset to the global reserve currency, it must become a widely accepted Medium of Exchange. This evolution matters for several reasons:
• Real-World Use Fuels Demand: When Bitcoin powers transactions, its value ties to tangible activity, not just market hype.
• Network Strength: More users mean a tougher, more valuable network—a classic network effect.
• Price Stability: Broader adoption could smooth out Bitcoin’s wild price rides, making it more practical for daily use.
Yet, hurdles abound. Bitcoin’s volatility is a dealbreaker for many—who’d spend it on a takeaway if it might double in value overnight? Then there’s the issue of “whales” or “max hodlers,” those holding vast swathes of Bitcoin. If too much of the supply sits idle, it starves the liquidity needed for an MOE to thrive.
The Hodler Debate: To Spend or Not to Spend?
A spirited clash within the community revolves around these large holders. Should they—like Saylor or early adopters—dip into their stacks to kickstart adoption? Hodling bolsters Bitcoin’s scarcity and SOV credentials, no doubt. But if the bulk of Bitcoin stays locked up, it could stall the growth of a bustling, transactional ecosystem.
Let’s be fair: hodling has been a winning play for many, turning small investments into fortunes. It’s a stretch to demand these pioneers shoulder the adoption burden alone. As Bitcoin weaves into the fabric of commerce—think businesses accepting it or workers earning it—transactional demand will rise organically. Over time, this could nudge even the staunchest hodlers to spend a bit, striking a balance between saving and circulating.
Growth and Stability: A Natural Progression
Bitcoin’s Compound Annual Growth Rate (CAGR) offers another angle. As its market cap balloons, its explosive growth is likely to taper off—a standard pattern for any asset. This slowdown could usher in greater stability, a boon for its MOE ambitions. Less volatility means less risk when spending Bitcoin, paving the way for it to move beyond investment portfolios and into wallets for everyday use.
This shift could redefine Bitcoin’s story, transforming it from a rollercoaster ride to a dependable currency. Voices like Jeff Booth and Jack Dorsey argue that MOE success is the key to sustaining Bitcoin’s SOV status. In short, while SOV lit the fuse, MOE could keep the fire burning.
The Blueprint: Steps to a Bitcoin Standard
So, how does Bitcoin ascend to world reserve status and birth a Bitcoin standard? Here’s a five-step vision:
1. SOV Momentum: Bitcoin’s allure as an inflation hedge and wealth preserver keeps drawing in holders, boosting its market cap and global clout.
2. MOE Infrastructure: Innovations like the Lightning Network must deliver fast, cheap transactions, making Bitcoin a practical choice for daily spending.
3. Value Stability: As adoption spreads and the market matures, Bitcoin’s price swings dampen, earning trust from users and merchants alike.
4. MOE Takeoff: With better tools and steadier value, Bitcoin becomes a go-to for transactions, amplifying its worth through a powerful network effect.
5. Global Crown: Governments and central banks start holding Bitcoin in reserves, using it for trade and settlements, cementing its place as the world’s reserve currency.
This isn’t a cakewalk. Scalability bottlenecks, regulatory pushback, and rival cryptocurrencies loom large. But if Bitcoin can clear these obstacles, it could become the backbone of global finance.
Harmony Over Division: SOV and MOE Together
Here’s the crux: SOV and MOE aren’t at odds—they’re partners in Bitcoin’s rise. Holding Bitcoin safeguards its scarcity and value; spending it spreads its reach and usefulness. Both are vital for the long haul.
At this pivotal moment, the Bitcoin community must rally around a dual-purpose ethos. We can:
• Educate: Help newcomers grasp Bitcoin’s twin roles as SOV and MOE.
• Innovate: Back tech that makes Bitcoin spending as easy as swiping a card.
• Talk: Host open forums to wrestle with differences and find unity.
The Final Word: Our Collective Challenge
Bitcoin’s shot at becoming the world’s reserve currency—and forging a Bitcoin standard—is as exhilarating as it is daunting. Its Store of Value roots have set the stage, but its Medium of Exchange potential will decide if it can topple fiat and redefine money itself.
The path is long, but the prize is transformative. By embracing both SOV and MOE, we can propel Bitcoin to new heights. Let’s grab this chance, dive into the debate, and build a future where Bitcoin leads the charge.
Your Turn: What’s the best way forward for Bitcoin? Should we lean harder into SOV, push MOE, or blend the two? Drop your thoughts below an

2025-04-07 13:17:50What is Growth Engineering? Before we start: if you’ve already filled out the What is your tech stack? survey: thank you! If you’ve not done so, your help will be greatly appreciated. It takes 5-15 minutes to complete. Those filling out will receive results before anyone else, and additional analysis from myself and Elin. Fill out this survey here.**
npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m
Growth engineering was barely known a decade ago, but today, most scaleups and many publicly traded tech companies have dedicated growth teams staffed by growth engineers. However, some software engineers are still suspicious of this new area because of its reputation for hacky code with little to no code coverage.
For this reason and others, I thought it would be interesting to learn more from an expert who can tell us all about the practicalities of this controversial domain. So I turned to Alexey Komissarouk, who’s been in growth engineering since 2016, and was in charge of it at online education platform, MasterClass. These days, Alexey lives in Tokyo, Japan, where he advises on growth engineering and teaches the Growth Engineering course at Reforge.
In today’s deep dive, Alexey covers:
- What is Growth Engineering? In the simplest terms: writing code to help a company make more money. But there are details to consider: like the company size where it makes sense to have a dedicated team do this.
- What do Growth Engineers work on? Business-facing work, empowerment and platform work are the main areas.
- Why Growth Engineers move faster than Product Engineers. Product Engineers ship to build: Growth Engineers ship to learn. Growth Engineers do take shortcuts that would make no sense when building for longevity – doing this on purpose.
- Tech stack. Common programming languages, monitoring and oncall, feature flags and experimentation, product analytics, review apps, and more.
- What makes a good Growth Engineer? Curiosity, “build to learn” mindset and a “Jack of all trades” approach.
- Where do Growth Engineers fit in? Usually part of the engineering department, either operating as with an “owner” or a “hitchiker” model.
- Becoming a Growth Engineer. A great area if you want to eventually become a founder or product manager – but even if not, it can accelerate your career growth. Working in Growth forces you to learn more about the business.
With that, it’s over to Alexey:
I’ll never forget the first time I made my employer a million dollars.
I was running a push notification A/B test for meal delivery startup Sprig, trying to boost repeat orders.
A push notification similar to what we tested to boost repeat orders
Initial results were unpromising; the push notification was not receiving many opens. Still, I wanted to be thorough: before concluding the idea was a failure, I wrote a SQL query to compare order volume for subsequent weeks between customers in test vs control.
The SQL used to figure out the push notification’s efficiency
As it turned out, our test group “beat” the control group by around 10%:
‘review_5_push’ was the new type of push notification. Roughly the same amount of users clicked it, but they placed 10% more in orders
I plugged the numbers into a significance calculator, which showed it was statistically significant – or “stat-sig” – and therefore highly unlikely to be a coincidence. This meant we had a winner on our hands! But how meaningful was it, really, and what would adding the push notification mean for revenue, if rolled out to 100% of users?
It turned out this experiment created an additional $1.5 million dollars, annually, with just one push notification. Wow!
I was hooked. Since that day, I've shipped hundreds of experimental “winners” which generated hundreds of millions of incremental revenue for my employers. But you never forget the first one. Moments like this is what growth engineering is all about.
1. What is Growth Engineering?
Essentially, growth engineering is the writing of code to make a company money. Of course, all code produced by a business on some level serves this purpose, but while Product Engineers focus on creating a Product worth paying for, Growth Engineers instead focus on making that good product have a good business. To this end, they focus on optimizing and refining key parts of the customer journey, such as:
- Getting more people to consider the product
- Converting them into paying customers
- Keeping them as customers for longer, and spending more
What kinds of companies employ Growth Engineers? Places you’ve heard of, like Meta, LinkedIn, DoorDash, Coinbase, and Dropbox, are some of the ones I’ve had students from. There’s also OpenAI, Uber, Tiktok, Tinder, Airbnb, Pinterest… the list of high-profile companies goes on. Most newer public consumer companies you’ve heard have a growth engineering org, too.
Typically, growth engineering orgs are started by companies at Series B stage and beyond, so long as they are selling to either consumers or businesses via SaaS. These are often places trying to grow extremely fast, and have enough software engineers that some can focus purely on growth. Before the Series B stage, a team is unlikely to be ready for growth for various reasons; likely that it hasn’t found product-market fit, or has no available headcount, or lacks the visitor traffic required to run A/B tests.
Cost is a consideration. A fully-loaded growth team consisting of a handful of engineers, a PM, and a designer costs approximately 1 million dollars annually. To justify this, a rule of thumb is to have at least $5 million dollars in recurring revenue – a milestone often achieved at around the Series B stage.
Despite the presence of growth engineering at many public consumer tech companies, the field itself is still quite new, as a discipline and as a proper title.
Brief history of growth engineering
When I joined Opendoor in 2016, there was a head of growth but no dedicated growth engineers, but there were by the time I left in 2020. At MasterClass soon after, there was a growth org and a dozen dedicated growth engineers. So when did growth engineering originate?
The story is that its origins lie at Facebook in 2007. The team was created by then-VP of platform and monetization Chamath Palihapitiya. Reforce founder and CEO Brian Balfour shares:
“Growth (the kind found on an org chart) began at Facebook under the direction of Chamath Palihapitiya. In 2007, he joined the early team in a nebulous role that fell somewhere between Product, Marketing, and Operations. According to his retelling of the story on Recode Decode, after struggling to accomplish anything meaningful in his first year on the job, he was on the verge of being fired.Sheryl Sandberg joined soon after him, and in a hail mary move he pitched her the game-changing idea that led to the creation of the first-ever growth team. This idea not only saved his job, but earned him the lion’s share of the credit for Facebook’s unprecedented growth.At the time, Sheryl and Mark asked him, “What do you call this thing where you help change the product, do some SEO and SEM, and algorithmically do this or that?”His response: “I don’t know, I just call that, like, Growth, you know, we’re going to try to grow. I’ll be the head of growing stuff."And just like that, Growth became a thing.”
Rather than focus on a particular product or feature, the growth team at Facebook focused on moving the needle, and figuring out which features to work on. These days, Meta employs hundreds if not thousands of growth engineers.
2. What do Growth Engineers work on?
Before we jump into concrete examples, let’s identify three primary focus areas that a growth engineer’s work usually involves.
- Business-facing work – improving the business directly
- Empowerment work – enabling other teams to improve the business
- Platform work – improving the velocity of the above activities
Let’s go through all three:
Business-facing work
This is the bread and butter of growth engineering, and follows a common pattern:
- Implement an idea. Try something big or small to try and move a key business metric, which differs by team but is typically related to conversion rate or retention.
- Quantify impact. Usually via A/B testing.
- Analyze impact. Await results, analyze impact, ship or roll back – then go back to the first step.
Experiments can lead to sweeping or barely noticeable changes. A famous “I can’t believe they needed to test this” was when Google figured out which shade of blue generates the most clicks. At MasterClass, we tested things across the spectrum:
- Small: should we show the price right on the homepage, was that a winner? Yes, but we framed it in monthly terms of $15/month, not $180/year.
- Medium: when browsing a course page, should we include related courses, or more details about the course itself? Was it a winner? After lengthy experimentation, it was hard to tell: both are valuable and we needed to strike the right balance.
- Large: when a potential customer is interested, do we take them straight to checkout, or encourage them to learn more? Counterintuitively, adding steps boosted conversion!
Empowerment
One of the best ways an engineer can move a target metric is by removing themselves as a bottleneck, so colleagues from marketing can iterate and optimize freely. To this end, growth engineers can either build internal tools or integrate self-serve MarTech (Marketing Technology) vendors.
With the right tool, there’s a lot that marketers can do without engineering’s involvement:
- Build and iterate on landing pages (Unbounce, Instapage, etc)
- Draft and send email, SMS and Push Notifications (Iterable, Braze, Customer.io, etc)
- Connect new advertising partners (Google Tag Manager, Segment, etc)
We go more into detail about benefits and applications in the MarTech section of Tech Stack, below.
Platform work
As a business scales, dedicated platform teams help improve stability and velocity for the teams they support. Within growth, this often includes initiatives like:
- Experiment Platform. Many parts of running an experiment can be standardized, from filtering the audience, to bucketing users properly, to observing statistical methodology. Historically, companies built reusable Experiment Platforms in-house, but more recently, vendors such as Eppo and Statsig have grown in popularity with fancy statistical methodologies like “Controlled Using Pre-Experiment Data” (CUPED) that give more signal with less data.
- Reusable components. Companies with standard front-end components for things like headlines, buttons, and images, dramatically reduce the time required to spin up a new page. No more "did you want 5 or 6 pixels here" with a designer; instead growth engineers rely on tools like Storybook to standardize and share reusable React components.
- Monitoring. Growth engineering benefits greatly from leveraging monitoring to compensate for reduced code coverage. High-quality business metric monitoring tools can detect bugs before they cause damage.
When I worked at MasterClass, having monitoring at the ad layer prevented at least one six-figure incident. One Friday, a marketer accidentally broadened the audience for a particular ad from US-only, to worldwide. In response, the Facebook Ad algorithm went on a spending spree, bringing in plenty of visitors from places like Brazil and India, whom we knew from past experience were unlikely to purchase the product. Fortunately, our monitoring noticed the low-performing campaign within minutes, and an alert was sent to the growth engineer on-call, who immediately reached out to the marketer and confirmed the change was unintentional, and then shut down the campaign.
Without this monitoring, a subtle targeting error like this could have gone unnoticed all weekend and would have eaten up $100,000+ of marketing budget. This episode shows that platform investment can benefit everyone; and since growth needs them most, it’s often the growth platform engineering team which implements them.
As the day-to-day work of a Growth Engineer shows, A/B tests are a critical tool to both measure success and learn. It’s a numbers game: the more A/B tests a team can run in a given quarter, the more of them will end up winners, making the team successful. It’s no wonder, then, that Growth Engineering will pull out all the stops to improve velocity.
3. Why Growth Engineers move faster than Product Engineers
On the surface, growth engineering teams look like product engineering ones; writing code, shipping pull requests, monitoring on-call, etc. So how do they move so much faster? The big reason lies in philosophy and focus, not technology. To quote Elena Verna, head of growth at Dropbox:
“Product Engineering teams ship to build; Growth Engineering teams ship to learn.”
Real-world case: price changes at Masterclass
A few years ago at MasterClass, the growth team wanted to see if changing our pricing model to multiple tiers would improve revenue.
Inspired in part by multiple pricing tiers for competitors such as Netflix (above), Disney Plus, and Hulu.
The “multiple pricing tier” proposal for MasterClass.
From a software engineering perspective, this was a highly complex project because:
- Backend engineering work: the backend did not yet support multiple pricing options, requiring a decent amount of engineering, and rigorous testing to make sure existing customers weren’t affected.
- Client app changes: on the device side, multiple platforms (iOS, iPad, Android, Roku, Apple TV, etc) would each need to be updated, including each relevant app store.
The software engineering team estimated that becoming a “multi-pricing-tier” company would take months across numerous engineering teams, and engineering leadership was unwilling to greenlight that significant investment.
We in growth engineering took this as a challenge. As usual, our goal was not just to add the new pricing model, but to learn how much money it might bring in. The approach we ended up proposing was a Fake Door test, which involves offering a not-yet-available option to customers to gauge interest level. This was risky, as taking a customer who’s ready to pay and telling them to join some kind of waiting list is a colossal waste, and risks making them feel like the target of a “bait and switch” trick.
We found a way. The key insight was that people are only offended about a “bait and switch”, if the “switch” is worse than the “bait.” Telling customers they would pay $100 and then switching to $150 would cause a riot, but starting at $150 and then saying “just kidding, it’s only $100” is a pleasant surprise.
The good kind of surprise.
So long as every test “pricing tier” is less appealing – higher prices, fewer features – than the current offering, we could “upgrade” customers after their initial selection. A customer choosing the cheapest tier gets extra features at no extra cost, while a customer choosing a more expensive tier is offered a discount.
We created three new tiers, at different prices. The new “premium” tier would describe the existing, original offering. Regardless of what potential customers selected, they got this “original offering,” during the experiment.
The best thing about this was that no backend changes were required. There were no real, new, back-end pricing plans; everybody ended up purchasing the same version of MasterClass for the same price, with the same features. The entirety of the engineering work was on building a new pricing page, and the “congratulations, you’ve been upgraded” popup. This took just a few days.
Within a couple of weeks, we had enough data to be confident the financial upside of moving to a multi-pricing-tier model would be significant. With this, we’re able to convince the rest of engineering’s leadership to invest in building the feature properly. In the end, launching multiple pricing tiers turned out to be one of the biggest revenue wins of the year.
Building a skyscraper vs building a tent
The MasterClass example demonstrates the spirit of growth engineering; focusing on building to learn, instead of building to last. Consider building skyscrapers versus tents.
Building a tent optimizes for speed of set-up and tear-down over longevity. You don’t think of a tent as one that is shoddy or low-quality compared to skyscrapers: it’s not even the same category of buildings! Growth engineers maximize use of lightweight materials. To stick with the tents vs skyscraper metaphor: we prioritize lightweight fabric materials over steel and concrete whenever possible. We only resort to traditional building materials when there’s no other choice, or when a direction is confirmed as correct. Quality is important – after all, a tent must keep out rain and mosquitoes. However, the speed-vs-durability tradeoff decision results in very different approaches and outcomes.
4. Tech stack
At first glance, growth and product engineers use the same tooling, and contribute to the same codebases. But growth engineering tends to be high-velocity, experiment-heavy, and with limited test coverage. This means that certain “nice to have” tools for product engineering are mission-critical for growth engineers.

2025-03-26 20:54:33Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.
That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.
As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.
Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.
Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.
The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.
When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.
Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

2025-03-15 23:00:40I want to see Nostr succeed. If you can think of a way I can help make that happen, I’m open to it. I’d like your suggestions.
My schedule’s shifting soon, and I could volunteer a few hours a week to a Nostr project. I won’t have more total time, but how I use it will change.
Why help? I care about freedom. Nostr’s one of the most powerful freedom tools I’ve seen in my lifetime. If I believe that, I should act on it.
I don’t care about money or sats. I’m not rich, I don’t have extra cash. That doesn’t drive me—freedom does. I’m volunteering, not asking for pay.
I’m not here for clout. I’ve had enough spotlight in my life; it doesn’t move me. If I wanted clout, I’d be on Twitter dropping basic takes. Clout’s easy. Freedom’s hard. I’d rather help anonymously. No speaking at events—small meetups are cool for the vibe, but big conferences? Not my thing. I’ll never hit a huge Bitcoin conference. It’s just not my scene.
That said, I could be convinced to step up if it’d really boost Nostr—as long as it’s legal and gets results.
In this space, I’d watch for social engineering. I watch out for it. I’m not here to make friends, just to help. No shade—you all seem great—but I’ve got a full life and awesome friends irl. I don’t need your crew or to be online cool. Connect anonymously if you want; I’d encourage it.
I’m sick of watching other social media alternatives grow while Nostr kinda stalls. I could trash-talk, but I’d rather do something useful.
Skills? I’m good at spotting social media problems and finding possible solutions. I won’t overhype myself—that’s weird—but if you’re responding, you probably see something in me. Perhaps you see something that I don’t see in myself.

2025-03-10 23:31:30Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.
Concern
One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.
Usually stolen bitcoin for the reserve creates a perverse incentive. If governments see a bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.
Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.
Optimism
The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.
Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.
This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.
Realism
We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.
We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

2025-03-07 00:26:37There is something quietly rebellious about stacking sats. In a world obsessed with instant gratification, choosing to patiently accumulate Bitcoin, one sat at a time, feels like a middle finger to the hype machine. But to do it right, you have got to stay humble. Stack too hard with your head in the clouds, and you will trip over your own ego before the next halving even hits.
Small Wins
Stacking sats is not glamorous. Discipline. Stacking every day, week, or month, no matter the price, and letting time do the heavy lifting. Humility lives in that consistency. You are not trying to outsmart the market or prove you are the next "crypto" prophet. Just a regular person, betting on a system you believe in, one humble stack at a time. Folks get rekt chasing the highs. They ape into some shitcoin pump, shout about it online, then go silent when they inevitably get rekt. The ones who last? They stack. Just keep showing up. Consistency. Humility in action. Know the game is long, and you are not bigger than it.
Ego is Volatile
Bitcoin’s swings can mess with your head. One day you are up 20%, feeling like a genius and the next down 30%, questioning everything. Ego will have you panic selling at the bottom or over leveraging the top. Staying humble means patience, a true bitcoin zen. Do not try to "beat” Bitcoin. Ride it. Stack what you can afford, live your life, and let compounding work its magic.
Simplicity
There is a beauty in how stacking sats forces you to rethink value. A sat is worth less than a penny today, but every time you grab a few thousand, you plant a seed. It is not about flaunting wealth but rather building it, quietly, without fanfare. That mindset spills over. Cut out the noise: the overpriced coffee, fancy watches, the status games that drain your wallet. Humility is good for your soul and your stack. I have a buddy who has been stacking since 2015. Never talks about it unless you ask. Lives in a decent place, drives an old truck, and just keeps stacking. He is not chasing clout, he is chasing freedom. That is the vibe: less ego, more sats, all grounded in life.
The Big Picture
Stack those sats. Do it quietly, do it consistently, and do not let the green days puff you up or the red days break you down. Humility is the secret sauce, it keeps you grounded while the world spins wild. In a decade, when you look back and smile, it will not be because you shouted the loudest. It will be because you stayed the course, one sat at a time. \ \ Stay Humble and Stack Sats. 🫡

2025-03-04 17:00:18This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.
Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.
A Jurisdiction with Strong Property Rights
Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.
Abundant Access to Fresh Water
Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.
Grow Your Own Food
A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.
Guns
The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.
A Strong Community You Can Depend On
No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.
Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

2025-05-29 12:26:43Saturday 9AM It’s a chilly Saturday morning in Warsaw, and I don’t want to get out of bed. This is not because of the hangover; it’s because I feel like a failure.
The first day of Bitcoin FilmFest was a whirlwind of workshops, panels and running between stages. The pitch competition did not go my way. Another ‘pitching rabbit’ (an actual experienced film-maker) was selected to win the €3,000 of funding.
Rather than get up and search for coffee, I replay the scenes in my head. What could I have done differently? Will investors ever believe in me: I’m just a writer with no contacts in the industry. Do I have what it takes to produce a film?
Eventually, I haul myself out of bed and walk to Amondo, the festival’s morning HQ (and technically, the smallest cinema in Europe). Upon arrival, I find Bitcoin psychonaut Ioni Appelberg holding court in front of around a dozen enraptured disciples. Soon, the conversation spills out to the street to free up space for more workshops.
I attend a talk on film funding, then pay for coffee using bitcoin. I see familiar faces from the two previous nights. We compare notes on Friday night and check the day’s schedule. The morning clouds burn off, and things feel a little brighter.
The afternoon session begins just a few blocks away in the towering Palace of Culture and Science. My role in today's proceedings is to present my freedom fiction project, 21 Futures, on the community stage. Other presentations range from rap videos and advice on finding jobs in bitcoin to hosting ‘Bitcoin Walks’. This is how we are fixing the culture.
Saturday 8PM I feel a tap on my shoulder. ‘Excuse me, Mr. Philip. Your car is waiting. The Producers’ Dinner is starting soon’.
What? Me, a producer? I’ve been taking part in some panels and talks, but I assumed my benefits as a guest were limited to a comped ticket and generous goodie bag.
Soon, I am sharing a taxi with a Dubai-based journalist, a Colombian director, and the cypherpunk sponsor of the pitch competition I didn’t win.
The pierogies I dreamed of earlier that day somehow manifest (happy endings do exist), and we enjoy a raucous dinner including obligatory slivovitz.
Sunday 2AM The last few hours of blur include a bracing city-bike ride in a crew of nine attendees back to the Palace of Culture, chatting with a fellow bitcoin meetup organiser, and vaguely promising to attend a weekend rave with a crew of Polish artists and musicians on the outskirts of London.
I leave the party while it’s still in full swing. In five hours, I have to wake up to complete my Run for Hal in Marshal Edward Rydz-Śmigły Park.
Thursday 9PM The festival kicks off in Samo Centrum on Pizza Day. I arrive in a taxi straight from a cramped flight (fix the airlines!), having not eaten for around ten hours.
The infectious sounds of softly spoken Aussie bitrocker Roger9000 pound into the damp night. I’m three beers in, being presented by the organisers to attendees like a (very tall) show pony. I try to explain more about my books, my publishing connections, my short film.
When I search for the food I ordered an hour ago, I find it has been given away. The stern-faced Polish pizza maker shrugs. ‘You not here.’
I’m so hungry I could cry (six hours of Ryanair can do that to a man). And then, a heroic Czech pleb donates half a pizza to me. Side note: this same heroic pleb accidentally locked me out of my film-funds while trying to fix a wallet bug on Sunday night.
I step out into the rain. Roger9000 reminds us we should have laser eyes well past 100k. I take a bite of pizza and life tastes good.
The Films Side events, artists, late nights, and pitcher’s regret is all well and good, but what of the films?
My highlights included Golden Rabbit winner No More Inflation — a moving narrative with interviews from two dozen economists, visionaries, and inflation survivors.
Hotel Bitcoin, was a surprisingly funny comedy romp about a group of idiots who happen across a valuable laptop.
Revolución Bitcoin — an approachable and thorough documentary aimed to bring greater adoption in the Spanish-speaking world.
And, as a short-fiction guy, I enjoyed the short films The Man Who Wouldn’t Cry, a visit to New York’s only Somali restaurant in Finding Home.
Sunday 7PM The award ceremony has just finished. I head to Amondo for the final time to pay for mojitos in bitcoin and say goodbye to newly made friends. I feel like I’ve met almost everyone in attendance. Are you going to BTC Prague?!? we ask as we part ways.
Of course, the best thing about any festival is the people, and BFF25 had a cast of characters worthy of any art house flick:
- The bright-eyed and confident frontwoman of the metal band Scardust
- A nostr-native artist selling his intricate canvases to the highest zapper
- A dreadlocked DJ who wears a pair of flying goggles on his head at all times
- An affable British filmmaker explaining the virtues of the word ‘chucklesome’
- A Duracell-powered organiser who seems to know every song, person, film, book, and guest at the festival.
Warsaw itself feels like it has a role to play, too. Birdsong and green parks contrast the foreboding Communist-era architecture. The weather changes faster than my mood — heavy greys transform to bright sunshine. The roads around the venue close on Sunday for a political rally. And there we are in the middle, watching our bitcoin films.
Tuesday 10AM I’m at home now, squinting at my email inbox and piles of washing, wondering when the hell I’ll find time. The festival Telegram group is still buzzing with activity. Side events like martial arts tutorials, trips to a shooting range, boat tours. 5AM photos of street graffiti, lost and found items, and people asking ‘is anyone still around?’
This was not just a film festival. BFF is truly a celebration of culture — Art. Books. Comedy. Music. Video. Talk. Connection.
All this pure signal has lifted my spirits so much that despite me being a newbie filmmaker, armed only with a biro, a couple of powerpoints and a Geyser fund page, I know I will succeed in my mission. It turns out you can just film things.
You may have attended bitcoin conferences before — you know, the ones with ‘fireside chats’, VIP areas, and overpriced merch. Bitcoin FilmFest is a moment in time. We are fixing the culture, year after year, until art can flourish again.
As fellow author Aaron Koenig commented during a panel session, ‘In twenty years, we won’t be drawing laser eyes and singing about honey badgers. Our grandchildren won’t understand the change we went through.’
Would I do it all again? Of course!
Join me next June in Warsaw.
I’ll be the tall one presenting his short animation premiere.
Philip Charter is a full-time writer and part-time cat herder. As well as writing for bitcoin founders and companies, he runs the 21 Futures fiction project.

2025-02-25 03:55:08Here’s a revised timeline of macro-level events from The Mandibles: A Family, 2029–2047 by Lionel Shriver, reimagined in a world where Bitcoin is adopted as a widely accepted form of money, altering the original narrative’s assumptions about currency collapse and economic control. In Shriver’s original story, the failure of Bitcoin is assumed amid the dominance of the bancor and the dollar’s collapse. Here, Bitcoin’s success reshapes the economic and societal trajectory, decentralizing power and challenging state-driven outcomes.
Part One: 2029–2032
-
2029 (Early Year)\ The United States faces economic strain as the dollar weakens against global shifts. However, Bitcoin, having gained traction emerges as a viable alternative. Unlike the original timeline, the bancor—a supranational currency backed by a coalition of nations—struggles to gain footing as Bitcoin’s decentralized adoption grows among individuals and businesses worldwide, undermining both the dollar and the bancor.
-
2029 (Mid-Year: The Great Renunciation)\ Treasury bonds lose value, and the government bans Bitcoin, labeling it a threat to sovereignty (mirroring the original bancor ban). However, a Bitcoin ban proves unenforceable—its decentralized nature thwarts confiscation efforts, unlike gold in the original story. Hyperinflation hits the dollar as the U.S. prints money, but Bitcoin’s fixed supply shields adopters from currency devaluation, creating a dual-economy split: dollar users suffer, while Bitcoin users thrive.
-
2029 (Late Year)\ Dollar-based inflation soars, emptying stores of goods priced in fiat currency. Meanwhile, Bitcoin transactions flourish in underground and online markets, stabilizing trade for those plugged into the bitcoin ecosystem. Traditional supply chains falter, but peer-to-peer Bitcoin networks enable local and international exchange, reducing scarcity for early adopters. The government’s gold confiscation fails to bolster the dollar, as Bitcoin’s rise renders gold less relevant.
-
2030–2031\ Crime spikes in dollar-dependent urban areas, but Bitcoin-friendly regions see less chaos, as digital wallets and smart contracts facilitate secure trade. The U.S. government doubles down on surveillance to crack down on bitcoin use. A cultural divide deepens: centralized authority weakens in Bitcoin-adopting communities, while dollar zones descend into lawlessness.
-
2032\ By this point, Bitcoin is de facto legal tender in parts of the U.S. and globally, especially in tech-savvy or libertarian-leaning regions. The federal government’s grip slips as tax collection in dollars plummets—Bitcoin’s traceability is low, and citizens evade fiat-based levies. Rural and urban Bitcoin hubs emerge, while the dollar economy remains fractured.
Time Jump: 2032–2047
- Over 15 years, Bitcoin solidifies as a global reserve currency, eroding centralized control. The U.S. government adapts, grudgingly integrating bitcoin into policy, though regional autonomy grows as Bitcoin empowers local economies.
Part Two: 2047
-
2047 (Early Year)\ The U.S. is a hybrid state: Bitcoin is legal tender alongside a diminished dollar. Taxes are lower, collected in BTC, reducing federal overreach. Bitcoin’s adoption has decentralized power nationwide. The bancor has faded, unable to compete with Bitcoin’s grassroots momentum.
-
2047 (Mid-Year)\ Travel and trade flow freely in Bitcoin zones, with no restrictive checkpoints. The dollar economy lingers in poorer areas, marked by decay, but Bitcoin’s dominance lifts overall prosperity, as its deflationary nature incentivizes saving and investment over consumption. Global supply chains rebound, powered by bitcoin enabled efficiency.
-
2047 (Late Year)\ The U.S. is a patchwork of semi-autonomous zones, united by Bitcoin’s universal acceptance rather than federal control. Resource scarcity persists due to past disruptions, but economic stability is higher than in Shriver’s original dystopia—Bitcoin’s success prevents the authoritarian slide, fostering a freer, if imperfect, society.
Key Differences
- Currency Dynamics: Bitcoin’s triumph prevents the bancor’s dominance and mitigates hyperinflation’s worst effects, offering a lifeline outside state control.
- Government Power: Centralized authority weakens as Bitcoin evades bans and taxation, shifting power to individuals and communities.
- Societal Outcome: Instead of a surveillance state, 2047 sees a decentralized, bitcoin driven world—less oppressive, though still stratified between Bitcoin haves and have-nots.
This reimagining assumes Bitcoin overcomes Shriver’s implied skepticism to become a robust, adopted currency by 2029, fundamentally altering the novel’s bleak trajectory.

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

2025-05-29 12:02:57Since 2019, the United States has been the country with the highest number of recorded cases, but Europe remains the most affected region.
According to a Binance report, the United States is the country that has recorded the greatest number of crypto-related kidnapping cases since 2019, despite a recent increase in incidents in France.
At the regional level, however, Europe remains the area with the highest number of crypto-related kidnappings: 59 cases over six years. During the same period, North America — which includes the United States and Canada — recorded 48 cases. Particularly notable is the data concerning the entire Asian continent, where 62 cases of crypto-related kidnappings have been documented, most of which are concentrated in Southeast Asian countries.
France emerges as a concerning hotspot for crypto kidnappings, with six recent cases, three of which have already occurred in 2025.
Source: Binance
The primary targets of these kidnappings include executives of crypto companies, professional traders, exchange employees, and entrepreneurs in the sector. Family members and close associates of victims are often targeted as well. An emerging phenomenon involves tourists suspected of possessing large amounts of cryptocurrency funds.
Kidnapping cases in 2025
The year 2025 has already seen particularly serious episodes of kidnappings linked to the digital asset world. The most notable case involved David Balland, co-founder of Ledger, and his wife, who were abducted from their residence in France earlier this January. The incident drew international attention from both the crypto industry and law enforcement agencies.
Another attempt took place in Paris, where armed men tried to kidnap the daughter and granddaughter of the CEO of the French exchange Paymium. Overseas, in New York, police arrested 37-year-old John Woeltz after discovering that an Italian tourist had been held captive and mistreated for weeks in a luxury Manhattan apartment.
Binance highlights a direct correlation between the price trend of Bitcoin and the increase in kidnappings. Since Bitcoin reached new all-time highs this year, attacks involving physical threats have also increased proportionally, the exchange suggests.
Source: Binance
In 2025 alone, at least 15 kidnapping episodes have already been documented, many involving ransom demands denominated in bitcoin.

2025-05-29 12:02:46Ed Suman, a 67-year-old retired artist who helped create large sculptures like Jeff Koons’ Balloon Dog, reportedly lost his entire life savings — over $2M in digital assets — in a sophisticated scam.
The incident is believed to be tied to the major data breach at Coinbase, one of the world’s largest digital asset exchanges.
Suman’s story is part of a bigger wave of attacks on digital asset holders using stolen personal info, and has triggered lawsuits, regulatory concerns and questions about digital security in the Bitcoin space.
In March 2025, Suman got a text message about suspicious activity on his Coinbase account. After Suman reported he was unaware of any unauthorized activity regarding his account, he got a call from a man who introduced himself as Brett Miller from Coinbase Security.
The guy sounded legit — he knew Suman’s setup, including that he used a Trezor Model One hardware wallet, a device meant to keep bitcoin and other digital assets offline and safe.
Suman told Bloomberg the guy knew everything, including the exact amount of digital assets he had.
The attacker persuaded Suman that his Trezor One hardware wallet and its funds were at risk and walked him through a “security procedure” that involved entering his seed phrase into a website that looked exactly like Coinbase, in order to “link his wallet to Coinbase”.
Nine days later, another guy called and repeated the process, saying the first one didn’t work.
And then, all of Suman’s digital assets — 17.5 bitcoin and 225 ether — were gone. At the time, bitcoin was around $103,000 and ether around $2,500, so the stolen stash was worth over $2 million.
Suman turned to digital assets after retiring from a decades-long art career. He stored his assets in cold storage to avoid the risks of online exchanges. He thought he did everything right.
Suman’s attackers didn’t pick his name out of a hat.
It looks like his personal info may have been leaked in the major breach at Coinbase. The company confirmed on May 15 that some of its customer service reps in India were bribed to access internal systems and steal customer data.
The stolen data included names, phone numbers, email addresses, balances and partial Social Security numbers.
According to Coinbase’s filing with the U.S. Securities and Exchange Commission, the breach may have started as early as January and affected nearly 1% of the company’s active monthly users — tens of thousands of people.
Hackers demanded $20M from Coinbase to keep the breach quiet but the company refused to pay. Coinbase says it fired the compromised agents and is setting aside $180M to $400M to reimburse affected users.
But so far, Suman hasn’t been told if he’ll be reimbursed.
Since the breach was disclosed, Coinbase has been hit with at least six lawsuits.
The lawsuits claim the company failed to protect user data and handled the aftermath poorly. One lawsuit filed in New York federal court on May 16 says Coinbase’s response was “inadequate, fragmented, and delayed.”
“Users were not promptly or fully informed of the compromise,” the complaint states, “and Coinbase did not immediately take meaningful steps to mitigate further harm.”
Some lawsuits are seeking damages, others are asking Coinbase to purge user data and improve its security. Coinbase has not commented on the lawsuits but pointed reporters to a blog post about its response.
Suman’s case is a cautionary tale across the Bitcoin world. He used a hardware wallet (considered the gold standard of Bitcoin security) and was still tricked through social engineering. Even the strongest security is useless if you don’t understand how Bitcoin works.
It’s never too early for Bitcoiners to start learning more about Bitcoin, especially on how to keep their stash safe. And the first lesson is “never ever share your seed phrase with anyone”.

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

2025-05-29 10:32:34This article gives an overview and comparison of the various funding sources that are available for LNbits.
LNbits is compatible with many Lightning Network wallets and can be on anything from a small VPS to a raspberry Pi on your home network or the LNbits SaaS platform.
Why your funding source matters
There are trade-offs between the various funding sources, for example funding LNbits using Strike requires the user to KYC themselves and has some privacy compromises versus funding LNbits from your own LND node. However the technical barrier to entry and node maintenance of using Strike is lower than using LND.
Self-custodial vs custodial connectors
Self-custodial Funding Sources
You run the node or service, keep the keys, and may need to manage LN channels. Good if you want control and have the skills to look after a server. Examples: LND (gRPC/REST), CoreLightning, Spark.
Self-custodial funding sources with an LSP
These funding sources offer a reasonable compromise between self-custody and some privacy trade offs. Examples: Phoenixd, Breez SDK, Boltz.
Custodial (or semi-custodial) funding sources
A third party runs the node. You plug LNbits into their API. Setup is quick and costs are low, but you trust the provider with your funds and privacy. Examples: Alby, OpenNode, Blink, ZBD, LNPay or another LNbits instance.
Funding sources compared
Below is a summary of the main options and how they stack up.

2025-05-29 10:01:20Jacopo Graziuso’s econometric study explains how the presence of Bitcoin is connected to the reduction of emissions and consumption in countries where it is mined.
The debate on Bitcoin’s environmental impact has been at the center of media attention for years, often characterized by approximate information and common misconceptions. But what emerges when data is analyzed? An answer comes from the study by Jacopo Graziuso, a recent graduate in Economics and Finance at the University of Salento, who dedicated his thesis to the topic, titled: “Bitcoin and energy: towards efficiency and environmental sustainability”.
“It bothers me when they tell me ‘Bitcoin pollutes, Bitcoin consumes’. This prompted me to write the thesis,” Graziuso tells Atlas21 microphones. “We live in an era of free and accessible information, yet disinformation reigns supreme, leading to beliefs without scientific foundation.”
Regarding his research work, Graziuso emphasizes: “I thank professor of econometrics Pierluigi Toma who knew what Bitcoin is and what mining is and gave me carte blanche for writing the thesis.”
The methodology used for the study is an econometric analysis based on data from 171 states from 2009 to 2024, with particular attention to the relationship between Bitcoin presence, greenhouse gas emissions (climate-altering gases) and energy consumption. To define Bitcoin’s “presence”, Graziuso created a variable that takes value 1 if at least 1% of the population uses (knows or has a wallet) the cryptocurrency or if it is present in state reserves.
The results of the research, conducted only with open source software, contradict the dominant narrative, Graziuso explains: “The analysis shows that Bitcoin’s presence in a state is associated with a decrease in greenhouse gas emissions. The study reveals that Bitcoin’s presence in a state reduces emissions by 39 megatons of CO2 equivalent. Essentially, where there is Bitcoin, climate-altering gas emissions decrease.”
Graziuso wants to emphasize the difference between consumption and pollution: “The problem is not consumption, it’s pollution. The distinction is fundamental: energy consumption is necessary for human development, while pollution derives from the use of inefficient energy sources. Currently China consumes over 4500% more than the entire Bitcoin network. Furthermore, thanks to mining flexibility, Bitcoin can help a state reduce general consumption.”
The research highlights how mining is acting as a catalyst for the adoption of renewable and nuclear energy. Mining naturally seeks the cheapest sources which increasingly coincide with the cleanest ones, the interviewee states.
One analyzed aspect is Bitcoin’s role as “buyer of last resort” for otherwise wasted energy. Graziuso cites several examples:
- Alps Blockchain, which has reactivated 32 disused hydroelectric plants in northern Italy and is working on building facilities in Paraguay and Ecuador exploiting hydroelectric energy;
- projects like Gridless that exploit excess energy from renewable sources in remote areas: “Not only does [Gridless] optimize the use of local energy resources, but it reinvests mining profits in communities, improving access to electricity and supporting the local economy,” writes Graziuso;
- in Texas, thanks to agreements with electricity grid operator ERCOT, miners exploit the operational flexibility of their machines to adapt consumption to grid needs, turning them off during peak moments and turning them back on when there is surplus energy, thus acting as buyers of last resort and contributing to stabilizing the electrical grid.
Another interesting aspect concerns the recovery of heat generated by machines: “Marathon Digital Holdings in Finland uses heat from its ASICs to heat 80,000 homes,” explains Graziuso. “Domestic applications are also being developed where ASIC heat is used for heating, further mitigating pollution.”
Immersion cooling, a technique that involves immersing mining machines in a dielectric fluid made in the laboratory, is cited as a promising solution to improve efficiency and reduce environmental impact. This way it is also possible to reduce machine noise, while the heat produced is dissipated by the dielectric material. Graziuso cites CleanSpark as an example of a completely carbon neutral mining farm that uses this technology: “This cooling technique allows us to safely overclock hardware, increasing performance by increasing operating frequency beyond factory settings,” states CleanSpark.
The thesis includes a section dedicated to zones that are emerging as sustainable mining hubs in different parts of the world:
- in Kenya and Ethiopia, “mining powered by hydroelectric energy is bringing drinking water and electricity to previously unserved communities,” declares Graziuso;
- in Georgia and Texas, Bitcoin mining is contributing to making the electrical grid more stable, intervening during peak demand moments and absorbing excess energy during overproduction periods;
- in Canada, companies like Upstream Data and Hut 8 Mining use mining to valorize excess or dispersed energy, including gas flaring in oil fields, thus reducing energy waste and emissions;
- the Makai project in Hawaii exploits OTEC (Ocean Thermal Energy Conversion) technology to convert ocean thermal energy into clean and renewable electricity.
Despite mining’s potential, obstacles to complete decarbonization still exist: “Decarbonization is still far away. Currently in many countries there are still state incentives from 40 years ago that favor fossil sources. Due to these incentives, today entrepreneurs’ costs are lower when fossil fuels are used. Once these state incentives end, perhaps the situation will improve. At the moment it is the miners who must voluntarily use renewable sources,” observes Graziuso. Italy, for example, continues to depend about 60% on fossil sources.
Another piece of data analyzed in the thesis is the improvement in energy efficiency of specialized mining machines: “In about 15 years, efficiency has improved by over 95%: this means decreased consumption and pollution,” emphasizes Graziuso.
“I hope this research contributes to spreading a more accurate and data-based narrative,” concludes Graziuso. “Bitcoin is not the problem, but could be part of the solution to the global energy challenge.”
The thesis will soon be published in its entirety online as a scientific paper.

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.

This is a test from Hive to Nostr, longform script, some markdown included. google link, 400 char. story.
In a lush pond, a green frog named Gus lived among lily pads. Each dawn, he croaked a cheerful tune, waking the dragonflies. One day, a heron eyed him hungrily. Gus, clever and quick, hopped beneath a broad leaf, blending perfectly. The heron, fooled, flew off. That evening, Gus sang louder, celebrating his escape. His friends—turtles and minnows—joined the chorus under the moon's glow. Gus’s courage inspired them all, proving wit outshines size. The pond thrived, with Gus as its spirited guardian, forever hopping and croaking in joy.

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

2025-02-01 11:16:04Federal employees must remove pronouns from email signatures by the end of the day. This directive comes from internal memos tied to two executive orders signed by Donald Trump. The orders target diversity and equity programs within the government.
CDC, Department of Transportation, and Department of Energy employees were affected. Staff were instructed to make changes in line with revised policy prohibiting certain language.
One CDC employee shared frustration, stating, “In my decade-plus years at CDC, I've never been told what I can and can't put in my email signature.” The directive is part of a broader effort to eliminate DEI initiatives from federal discourse.

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.

2025-05-29 09:01:38The company is facing a class action lawsuit following a stock price drop triggered by the delayed disclosure of a December data breach.
Coinbase finds itself at the center of a legal storm after being hit with a class action lawsuit filed by shareholders. The lawsuit stems from a decline in the company’s stock price, which occurred after the belated communication of a cybersecurity incident.
The class action, filed in the United States District Court for the Eastern District of Pennsylvania, names investor Brady Nessler as the lead plaintiff. The suit claims that the platform’s shareholders suffered “substantial losses and damages” due to the company’s alleged failure to disclose material information.
Investors accuse the company of not promptly revealing crucial details that could have influenced investment decisions. Among the main allegations is the failure to immediately communicate a data breach that took place last December.
Details of the breach
On May 15, Coinbase publicly disclosed the news of a cyberattack that occurred last December. The incident involved cybercriminals who managed to corrupt several company employees, gaining unauthorized access to customer personal data.
The delayed disclosure of the data breach triggered an immediate stock market reaction. Coinbase shares fell 7.2%, closing the day at $244.
The exchange estimated that the financial impact of the data breach could range between $180 million and $400 million. These costs would cover both expenses to restore security systems and potential reimbursements to customers affected by the incident.
The lawsuit highlights that the company should have communicated these estimated costs to investors more promptly, allowing them to make informed decisions about their investments.
Additional allegations in the lawsuit
In addition to the data breach, the lawsuit lists a series of other alleged communication failures by the company. Among them is the non-disclosure of a violation by CB Payments — Coinbase’s UK subsidiary — of a 2020 agreement with the UK’s Financial Conduct Authority.
The class action covers all investors who acquired company shares between April 14, 2021, and May 14, 2025 — a period during which the allegedly omitted information is believed to have negatively affected the stock price.
The legal action doesn’t target the company alone but also names top executives including CEO Brian Armstrong and CFO Alesia Haas among the defendants.

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

2025-05-29 07:01:39A new Bitwise report reveals notable growth for institutional investments in bitcoin over the coming years.
According to the latest forecasts from asset management firm Bitwise, capital flows into Bitcoin could exceed $120 billion by the end of 2025, with projections reaching $300 billion the following year.
This growth is rooted in the rising interest from sovereign wealth funds, publicly traded companies, state treasuries, and institutional investment vehicles such as spot exchange-traded funds (ETFs). Analysts expect the number of companies holding bitcoin in their treasuries to double by the end of 2026.
Bitwise’s analysis highlights how Bitcoin is no longer seen solely as a speculative asset but is emerging as a serious contender for the role of global store of value.
The report notes that, according to its authors, global wealth is gradually moving away from traditional safe havens like gold and shifting toward Bitcoin.
Spot ETF boom
Spot Bitcoin ETFs in the United States have outperformed all expectations throughout 2024. These financial instruments have attracted over $36.2 billion in net inflows, surpassing by twenty times the early performance of SPDR Gold Shares (GLD), historically the most successful commodity ETF.
Source: Bitwise
In just twelve months, U.S. spot ETFs have accumulated $125 billion in assets under management (AUM). Bitwise projections suggest that annual inflows could reach $100 billion by 2027.
However, approximately $35 billion in capital remained on the sidelines in 2024 due to regulatory restrictions at financial institutions such as Morgan Stanley and Goldman Sachs.
States consider a bitcoin reserve
Bitwise’s analysis also highlights Bitcoin’s growing appeal beyond Wall Street. Publicly traded companies currently hold over 1.1 million BTC, worth more than $125 billion. Sovereign governments collectively own more than 500,000 BTC, with the United States, China, and the United Kingdom leading the rankings.
In its base scenario, Bitwise forecasts a modest reallocation of institutional and sovereign assets toward Bitcoin: 5% of government gold reserves and 0.5% of assets from major wealth management platforms. Even under these conservative assumptions, total bitcoin inflows could reach $420 billion over 2025-2026.
In a more optimistic scenario, with 10% of gold reserves and 1% of managed portfolios shifting to Bitcoin, inflows could exceed $920 billion, absorbing more than 9 million bitcoins — around 40% of the total supply.

JD Vance Says “Bitcoin Finally Has a Champion in the White House”In a headline speech at the Bitcoin 2025 Conference today, U.S. Vice President JD Vance declared Bitcoin’s growing role in national policy and promised a new era of federal support under the Trump administration. “It’s great to be here with Bitcoin at $108k and to be the Vice President of the United States,” Vance opened. “This isn’t a conference of people. This is a movement.”
Thanking David Bailey, and key figures like Cameron and Tyler Winklevoss, Vance emphasized, “They took a big step and everyone else followed.” He also shouted out Coinbase for their participation at the event as well.
In sharp contrast to past administrations, Vance was clear: “What we’ve done in the Trump administration in digital asset policy is only the beginning. Crypto finally has a champion and an ally in the White House.”
JUST IN:

— Bitcoin Magazine (@BitcoinMagazine) May 28, 2025
Vance underscored the grassroots energy of the Bitcoin community: “This gets decided by the people, by you—not unelected bureaucrats.”
He laid out three key priorities for the administration, the first being Widespread Adoption – “Fifty million Americans own Bitcoin. I think it’s gonna be 100 million before too long.” The second being Legislative Support– “We are optimistic the Senate will pass the clean GENIUS Act. Stablecoins don’t threaten the U.S. dollar—they’re a force multiplier for the economic mission.” And third, Clear Regulation – “We need a transparent regulatory framework that incorporates Bitcoin into the mainstream economy.”
Referencing broader concerns about institutional overreach, Vance said, “Crypto is a hedge against bad policymaking in Washington.”
Promising protection and partnership from Washington, he vowed, “You deserve respect and support from your government—not bureaucrats trying to tear you down. We are ending the weaponization of federal agencies against this community.”
Vance concluded stating, “Bitcoin is digital gold, but none of you are—unless you get involved,” discussing how Bitcoin is here to stay, but only if the American people get involved and build the industry. “Where Bitcoin is going is strategically important to the U.S. We’re gonna make the right decisions, and that depends on you being a part of the conversation.”
The message that Vance made was abundantly clear. Bitcoin is in the hands of the American people, and it is up to the citizens to make a lasting impact with it.

via levelsio
Over the weekend, prolific vibe coder levelsio took to X to complain about the state of housing affordability across Europe. Something that I was very happy to see considering the fact that there is a massive real estate affordability crisis across much of the world and it is important that people who are respected and have platforms speak out when they identify the problem as well. More eyes and focus on the problem is how something begins to get solved.
With that being said, I think levelsio is missing the forest for the trees by blaming institutionalized NIMBYism, burdensome regulations and governments hoarding land that should instead be given to developers to produce more housing supply. I quote tweeted this particular tweet on the subject from levelsio and wanted to take some time today to republish those thoughts here and expand on the topic.
It’s almost as if real estate is being used as a store of value asset instead of the consumable good that it is.
What @levelsio is observing here is called a “monetary premium”. A monetary premium is the value added on top of the consumable/aesthetic/location value of real estate.
This monetary premium exist because central banks and governments have distorted the market for money and people are forced to push value into assets that are scarce relative to dollars. Over the last 50 years real estate has been one of the relatively scarce assets of choice.
The housing affordability crisis is a negative externality of the market reaction to the corruption of money. It can only be fixed by re-introducing hard money into the economy that enables people to store value reliably. If that emerges they won’t have to store value in real estate, the monetary premium of real estate will dissolve and prices will correct to their proper valuations.
This is one of the problems that bitcoin solves.
It’s still early yet, but more and more people are recognizing the utility provided by a neutral reserve asset that can’t be manipulated by central planners. At scale, the effect on assets that have accumulated a monetary premium over decades will be material. All of these assets are significantly overvalued and their monetary premium are leaking into bitcoin.
Put another way, "It's the money, stupid." Now, this isn't to say that the supply of housing in certain areas being artificially restricted isn't having an effect on the price of housing. This is certainly true, especially in cities like San Francisco where there is a relatively strong demand because of the economic density of the area and the desire of many high agency and productive people to live there. But I would put forth that the monetary premium is still the bigger problem and no amount of de-regulation to enable the supply of housing to increase will solve the affordability crisis in the long-run. The only way to get to the root of this specific problem is via bitcoin's mainstream adoption as an apolitical uncontrollable asset with completely idiosyncratic risks when compared to any individual asset class.
Let's say the government did ease up regulations and local NIMBY sympathetics were shoved in a corner to allow new units to be built. This doesn't solve the problem in the short-run because there is a time-delay between when regulations are lifted and when new supply actually makes it to market. In the interim, governments and central banks are inevitably going to go further into debt and be forced to print money to monetize that debt. This will exacerbate inflation and even if new real estate units are brought to market, the builders/owners of those properties will likely have to demand elevated prices to attempt to keep up with inflation.
This also does nothing to solve the problem of real income and wage growth, which are significantly lagging real inflation. Even if prices came down because of a surge in supply, could the Common Man afford a down payment on the property? I'd be shocked if this was the case. And since it's likely not the case the only way to get people into these houses as "owners" would be to offer them zero-down financing, which makes people feel richer than they actually are and leads them to make financially ruinous decisions.
It's the money, stupid. People need a way to save so that they can buy in the first place. Fiat currency doesn't allow this and the only people who can save effectively are those who make enough money to funnel into substitute store of value assets like real estate.
As it stands today, the price-to-income ratio of real estate is 5.0x and the price-t0-rent index is 1.36. Up from 3.3x and 1.14x respectively where the metrics sat in the year 2000. The growth in these ratios is driven predominately via their monetary premium.
And guess what, it's about to get much worse. Donald Trump, Treasury Secretary Scott Bessent and Elon Musk have all signaled that the plan moving forward is to attempt to drive growth and productivity as high as possible while also letting deficits and the debt increase unabated, which means that inflation is likely to continue unabated and potentially increase.
It might make sense to get some bitcoin if that is the case.

"Whale in the Pool" Risk That Could Destroy MSTY Investors
Jessy Gilger raised serious concerns about MSTY and similar derivative products that promise eye-popping yields. He pointed to the COVID crash where gold mining ETFs using derivatives collapsed 95% and never recovered, despite gold itself performing well. Jessy noted that while his team calculated reasonable MicroStrategy covered call yields of 16-22%, MSTY advertises 120% annualized distributions - a red flag that suggests these aren't sustainable dividends from profits, but potentially just returning investors' own capital.
"If a whale pees in the pool, everyone is affected." - Jessy Gilger
Jessy explained that when large investors need to exit these pooled products during market stress, they must sell derivative positions into illiquid markets with no buyers, potentially triggering catastrophic losses for all participants. His solution? Private pools through separately managed accounts that achieve similar income goals without the contagion risk of being trapped with panicking whales.

2025-01-13 21:50:59Bitcoin is more than money, more than an asset, and more than a store of value. Bitcoin is a Prime Mover, an enabler and it ignites imaginations. It certainly fueled an idea in my mind. The idea integrates sensors, computational prowess, actuated machinery, power conversion, and electronic communications to form an autonomous, machined creature roaming forests and harvesting the most widespread and least energy-dense fuel source available. I call it the Forest Walker and it eats wood, and mines Bitcoin.
I know what you're thinking. Why not just put Bitcoin mining rigs where they belong: in a hosted facility sporting electricity from energy-dense fuels like natural gas, climate-controlled with excellent data piping in and out? Why go to all the trouble building a robot that digests wood creating flammable gasses fueling an engine to run a generator powering Bitcoin miners? It's all about synergy.
Bitcoin mining enables the realization of multiple, seemingly unrelated, yet useful activities. Activities considered un-profitable if not for Bitcoin as the Prime Mover. This is much more than simply mining the greatest asset ever conceived by humankind. It’s about the power of synergy, which Bitcoin plays only one of many roles. The synergy created by this system can stabilize forests' fire ecology while generating multiple income streams. That’s the realistic goal here and requires a brief history of American Forest management before continuing.
Smokey The Bear
In 1944, the Smokey Bear Wildfire Prevention Campaign began in the United States. “Only YOU can prevent forest fires” remains the refrain of the Ad Council’s longest running campaign. The Ad Council is a U.S. non-profit set up by the American Association of Advertising Agencies and the Association of National Advertisers in 1942. It would seem that the U.S. Department of the Interior was concerned about pesky forest fires and wanted them to stop. So, alongside a national policy of extreme fire suppression they enlisted the entire U.S. population to get onboard via the Ad Council and it worked. Forest fires were almost obliterated and everyone was happy, right? Wrong.
Smokey is a fantastically successful bear so forest fires became so few for so long that the fuel load - dead wood - in forests has become very heavy. So heavy that when a fire happens (and they always happen) it destroys everything in its path because the more fuel there is the hotter that fire becomes. Trees, bushes, shrubs, and all other plant life cannot escape destruction (not to mention homes and businesses). The soil microbiology doesn’t escape either as it is burned away even in deeper soils. To add insult to injury, hydrophobic waxy residues condense on the soil surface, forcing water to travel over the ground rather than through it eroding forest soils. Good job, Smokey. Well done, Sir!
Most terrestrial ecologies are “fire ecologies”. Fire is a part of these systems’ fuel load and pest management. Before we pretended to “manage” millions of acres of forest, fires raged over the world, rarely damaging forests. The fuel load was always too light to generate fires hot enough to moonscape mountainsides. Fires simply burned off the minor amounts of fuel accumulated since the fire before. The lighter heat, smoke, and other combustion gasses suppressed pests, keeping them in check and the smoke condensed into a plant growth accelerant called wood vinegar, not a waxy cap on the soil. These fires also cleared out weak undergrowth, cycled minerals, and thinned the forest canopy, allowing sunlight to penetrate to the forest floor. Without a fire’s heat, many pine tree species can’t sow their seed. The heat is required to open the cones (the seed bearing structure) of Spruce, Cypress, Sequoia, Jack Pine, Lodgepole Pine and many more. Without fire forests can’t have babies. The idea was to protect the forests, and it isn't working.
So, in a world of fire, what does an ally look like and what does it do?
Meet The Forest Walker
For the Forest Walker to work as a mobile, autonomous unit, a solid platform that can carry several hundred pounds is required. It so happens this chassis already exists but shelved.
Introducing the Legged Squad Support System (LS3). A joint project between Boston Dynamics, DARPA, and the United States Marine Corps, the quadrupedal robot is the size of a cow, can carry 400 pounds (180 kg) of equipment, negotiate challenging terrain, and operate for 24 hours before needing to refuel. Yes, it had an engine. Abandoned in 2015, the thing was too noisy for military deployment and maintenance "under fire" is never a high-quality idea. However, we can rebuild it to act as a platform for the Forest Walker; albeit with serious alterations. It would need to be bigger, probably. Carry more weight? Definitely. Maybe replace structural metal with carbon fiber and redesign much as 3D printable parts for more effective maintenance.
The original system has a top operational speed of 8 miles per hour. For our purposes, it only needs to move about as fast as a grazing ruminant. Without the hammering vibrations of galloping into battle, shocks of exploding mortars, and drunken soldiers playing "Wrangler of Steel Machines", time between failures should be much longer and the overall energy consumption much lower. The LS3 is a solid platform to build upon. Now it just needs to be pulled out of the mothballs, and completely refitted with outboard equipment.
The Small Branch Chipper
When I say “Forest fuel load” I mean the dead, carbon containing litter on the forest floor. Duff (leaves), fine-woody debris (small branches), and coarse woody debris (logs) are the fuel that feeds forest fires. Walk through any forest in the United States today and you will see quite a lot of these materials. Too much, as I have described. Some of these fuel loads can be 8 tons per acre in pine and hardwood forests and up to 16 tons per acre at active logging sites. That’s some big wood and the more that collects, the more combustible danger to the forest it represents. It also provides a technically unlimited fuel supply for the Forest Walker system.
The problem is that this detritus has to be chewed into pieces that are easily ingestible by the system for the gasification process (we’ll get to that step in a minute). What we need is a wood chipper attached to the chassis (the LS3); its “mouth”.
A small wood chipper handling material up to 2.5 - 3.0 inches (6.3 - 7.6 cm) in diameter would eliminate a substantial amount of fuel. There is no reason for Forest Walker to remove fallen trees. It wouldn’t have to in order to make a real difference. It need only identify appropriately sized branches and grab them. Once loaded into the chipper’s intake hopper for further processing, the beast can immediately look for more “food”. This is essentially kindling that would help ignite larger logs. If it’s all consumed by Forest Walker, then it’s not present to promote an aggravated conflagration.
I have glossed over an obvious question: How does Forest Walker see and identify branches and such? LiDaR (Light Detection and Ranging) attached to Forest Walker images the local area and feed those data to onboard computers for processing. Maybe AI plays a role. Maybe simple machine learning can do the trick. One thing is for certain: being able to identify a stick and cause robotic appendages to pick it up is not impossible.
Great! We now have a quadrupedal robot autonomously identifying and “eating” dead branches and other light, combustible materials. Whilst strolling through the forest, depleting future fires of combustibles, Forest Walker has already performed a major function of this system: making the forest safer. It's time to convert this low-density fuel into a high-density fuel Forest Walker can leverage. Enter the gasification process.
The Gassifier
The gasifier is the heart of the entire system; it’s where low-density fuel becomes the high-density fuel that powers the entire system. Biochar and wood vinegar are process wastes and I’ll discuss why both are powerful soil amendments in a moment, but first, what’s gasification?
Reacting shredded carbonaceous material at high temperatures in a low or no oxygen environment converts the biomass into biochar, wood vinegar, heat, and Synthesis Gas (Syngas). Syngas consists primarily of hydrogen, carbon monoxide, and methane. All of which are extremely useful fuels in a gaseous state. Part of this gas is used to heat the input biomass and keep the reaction temperature constant while the internal combustion engine that drives the generator to produce electrical power consumes the rest.
Critically, this gasification process is “continuous feed”. Forest Walker must intake biomass from the chipper, process it to fuel, and dump the waste (CO2, heat, biochar, and wood vinegar) continuously. It cannot stop. Everything about this system depends upon this continual grazing, digestion, and excretion of wastes just as a ruminal does. And, like a ruminant, all waste products enhance the local environment.
When I first heard of gasification, I didn’t believe that it was real. Running an electric generator from burning wood seemed more akin to “conspiracy fantasy” than science. Not only is gasification real, it’s ancient technology. A man named Dean Clayton first started experiments on gasification in 1699 and in 1901 gasification was used to power a vehicle. By the end of World War II, there were 500,000 Syngas powered vehicles in Germany alone because of fossil fuel rationing during the war. The global gasification market was $480 billion in 2022 and projected to be as much as $700 billion by 2030 (Vantage Market Research). Gasification technology is the best choice to power the Forest Walker because it’s self-contained and we want its waste products.
Biochar: The Waste
Biochar (AKA agricultural charcoal) is fairly simple: it’s almost pure, solid carbon that resembles charcoal. Its porous nature packs large surface areas into small, 3 dimensional nuggets. Devoid of most other chemistry, like hydrocarbons (methane) and ash (minerals), biochar is extremely lightweight. Do not confuse it with the charcoal you buy for your grill. Biochar doesn’t make good grilling charcoal because it would burn too rapidly as it does not contain the multitude of flammable components that charcoal does. Biochar has several other good use cases. Water filtration, water retention, nutrient retention, providing habitat for microscopic soil organisms, and carbon sequestration are the main ones that we are concerned with here.
Carbon has an amazing ability to adsorb (substances stick to and accumulate on the surface of an object) manifold chemistries. Water, nutrients, and pollutants tightly bind to carbon in this format. So, biochar makes a respectable filter and acts as a “battery” of water and nutrients in soils. Biochar adsorbs and holds on to seven times its weight in water. Soil containing biochar is more drought resilient than soil without it. Adsorbed nutrients, tightly sequestered alongside water, get released only as plants need them. Plants must excrete protons (H+) from their roots to disgorge water or positively charged nutrients from the biochar's surface; it's an active process.
Biochar’s surface area (where adsorption happens) can be 500 square meters per gram or more. That is 10% larger than an official NBA basketball court for every gram of biochar. Biochar’s abundant surface area builds protective habitats for soil microbes like fungi and bacteria and many are critical for the health and productivity of the soil itself.
The “carbon sequestration” component of biochar comes into play where “carbon credits” are concerned. There is a financial market for carbon. Not leveraging that market for revenue is foolish. I am climate agnostic. All I care about is that once solid carbon is inside the soil, it will stay there for thousands of years, imparting drought resiliency, fertility collection, nutrient buffering, and release for that time span. I simply want as much solid carbon in the soil because of the undeniably positive effects it has, regardless of any climactic considerations.
Wood Vinegar: More Waste
Another by-product of the gasification process is wood vinegar (Pyroligneous acid). If you have ever seen Liquid Smoke in the grocery store, then you have seen wood vinegar. Principally composed of acetic acid, acetone, and methanol wood vinegar also contains ~200 other organic compounds. It would seem intuitive that condensed, liquefied wood smoke would at least be bad for the health of all living things if not downright carcinogenic. The counter intuition wins the day, however. Wood vinegar has been used by humans for a very long time to promote digestion, bowel, and liver health; combat diarrhea and vomiting; calm peptic ulcers and regulate cholesterol levels; and a host of other benefits.
For centuries humans have annually burned off hundreds of thousands of square miles of pasture, grassland, forest, and every other conceivable terrestrial ecosystem. Why is this done? After every burn, one thing becomes obvious: the almost supernatural growth these ecosystems exhibit after the burn. How? Wood vinegar is a component of this growth. Even in open burns, smoke condenses and infiltrates the soil. That is when wood vinegar shows its quality.
This stuff beefs up not only general plant growth but seed germination as well and possesses many other qualities that are beneficial to plants. It’s a pesticide, fungicide, promotes beneficial soil microorganisms, enhances nutrient uptake, and imparts disease resistance. I am barely touching a long list of attributes here, but you want wood vinegar in your soil (alongside biochar because it adsorbs wood vinegar as well).
The Internal Combustion Engine
Conversion of grazed forage to chemical, then mechanical, and then electrical energy completes the cycle. The ICE (Internal Combustion Engine) converts the gaseous fuel output from the gasifier to mechanical energy, heat, water vapor, and CO2. It’s the mechanical energy of a rotating drive shaft that we want. That rotation drives the electric generator, which is the heartbeat we need to bring this monster to life. Luckily for us, combined internal combustion engine and generator packages are ubiquitous, delivering a defined energy output given a constant fuel input. It’s the simplest part of the system.
The obvious question here is whether the amount of syngas provided by the gasification process will provide enough energy to generate enough electrons to run the entire system or not. While I have no doubt the energy produced will run Forest Walker's main systems the question is really about the electrons left over. Will it be enough to run the Bitcoin mining aspect of the system? Everything is a budget.
CO2 Production For Growth
Plants are lollipops. No matter if it’s a tree or a bush or a shrubbery, the entire thing is mostly sugar in various formats but mostly long chain carbohydrates like lignin and cellulose. Plants need three things to make sugar: CO2, H2O and light. In a forest, where tree densities can be quite high, CO2 availability becomes a limiting growth factor. It’d be in the forest interests to have more available CO2 providing for various sugar formation providing the organism with food and structure.
An odd thing about tree leaves, the openings that allow gasses like the ever searched for CO2 are on the bottom of the leaf (these are called stomata). Not many stomata are topside. This suggests that trees and bushes have evolved to find gasses like CO2 from below, not above and this further suggests CO2 might be in higher concentrations nearer the soil.
The soil life (bacterial, fungi etc.) is constantly producing enormous amounts of CO2 and it would stay in the soil forever (eventually killing the very soil life that produces it) if not for tidal forces. Water is everywhere and whether in pools, lakes, oceans or distributed in “moist” soils water moves towards to the moon. The water in the soil and also in the water tables below the soil rise toward the surface every day. When the water rises, it expels the accumulated gasses in the soil into the atmosphere and it’s mostly CO2. It’s a good bet on how leaves developed high populations of stomata on the underside of leaves. As the water relaxes (the tide goes out) it sucks oxygenated air back into the soil to continue the functions of soil life respiration. The soil “breathes” albeit slowly.
The gasses produced by the Forest Walker’s internal combustion engine consist primarily of CO2 and H2O. Combusting sugars produce the same gasses that are needed to construct the sugars because the universe is funny like that. The Forest Walker is constantly laying down these critical construction elements right where the trees need them: close to the ground to be gobbled up by the trees.
The Branch Drones
During the last ice age, giant mammals populated North America - forests and otherwise. Mastodons, woolly mammoths, rhinos, short-faced bears, steppe bison, caribou, musk ox, giant beavers, camels, gigantic ground-dwelling sloths, glyptodons, and dire wolves were everywhere. Many were ten to fifteen feet tall. As they crashed through forests, they would effectively cleave off dead side-branches of trees, halting the spread of a ground-based fire migrating into the tree crown ("laddering") which is a death knell for a forest.
These animals are all extinct now and forests no longer have any manner of pruning services. But, if we build drones fitted with cutting implements like saws and loppers, optical cameras and AI trained to discern dead branches from living ones, these drones could effectively take over pruning services by identifying, cutting, and dropping to the forest floor, dead branches. The dropped branches simply get collected by the Forest Walker as part of its continual mission.
The drones dock on the back of the Forest Walker to recharge their batteries when low. The whole scene would look like a grazing cow with some flies bothering it. This activity breaks the link between a relatively cool ground based fire and the tree crowns and is a vital element in forest fire control.
The Bitcoin Miner
Mining is one of four monetary incentive models, making this system a possibility for development. The other three are US Dept. of the Interior, township, county, and electrical utility company easement contracts for fuel load management, global carbon credits trading, and data set sales. All the above depends on obvious questions getting answered. I will list some obvious ones, but this is not an engineering document and is not the place for spreadsheets. How much Bitcoin one Forest Walker can mine depends on everything else. What amount of biomass can we process? Will that biomass flow enough Syngas to keep the lights on? Can the chassis support enough mining ASICs and supporting infrastructure? What does that weigh and will it affect field performance? How much power can the AC generator produce?
Other questions that are more philosophical persist. Even if a single Forest Walker can only mine scant amounts of BTC per day, that pales to how much fuel material it can process into biochar. We are talking about millions upon millions of forested acres in need of fuel load management. What can a single Forest Walker do? I am not thinking in singular terms. The Forest Walker must operate as a fleet. What could 50 do? 500?
What is it worth providing a service to the world by managing forest fuel loads? Providing proof of work to the global monetary system? Seeding soil with drought and nutrient resilience by the excretion, over time, of carbon by the ton? What did the last forest fire cost?
The Mesh Network
What could be better than one bitcoin mining, carbon sequestering, forest fire squelching, soil amending behemoth? Thousands of them, but then they would need to be able to talk to each other to coordinate position, data handling, etc. Fitted with a mesh networking device, like goTenna or Meshtastic LoRa equipment enables each Forest Walker to communicate with each other.
Now we have an interconnected fleet of Forest Walkers relaying data to each other and more importantly, aggregating all of that to the last link in the chain for uplink. Well, at least Bitcoin mining data. Since block data is lightweight, transmission of these data via mesh networking in fairly close quartered environs is more than doable. So, how does data transmit to the Bitcoin Network? How do the Forest Walkers get the previous block data necessary to execute on mining?
Back To The Chain
Getting Bitcoin block data to and from the network is the last puzzle piece. The standing presumption here is that wherever a Forest Walker fleet is operating, it is NOT within cell tower range. We further presume that the nearest Walmart Wi-Fi is hours away. Enter the Blockstream Satellite or something like it.
A separate, ground-based drone will have two jobs: To stay as close to the nearest Forest Walker as it can and to provide an antennae for either terrestrial or orbital data uplink. Bitcoin-centric data is transmitted to the "uplink drone" via the mesh networked transmitters and then sent on to the uplink and the whole flow goes in the opposite direction as well; many to one and one to many.
We cannot transmit data to the Blockstream satellite, and it will be up to Blockstream and companies like it to provide uplink capabilities in the future and I don't doubt they will. Starlink you say? What’s stopping that company from filtering out block data? Nothing because it’s Starlink’s system and they could decide to censor these data. It seems we may have a problem sending and receiving Bitcoin data in back country environs.
But, then again, the utility of this system in staunching the fuel load that creates forest fires is extremely useful around forested communities and many have fiber, Wi-Fi and cell towers. These communities could be a welcoming ground zero for first deployments of the Forest Walker system by the home and business owners seeking fire repression. In the best way, Bitcoin subsidizes the safety of the communities.
Sensor Packages
LiDaR
The benefit of having a Forest Walker fleet strolling through the forest is the never ending opportunity for data gathering. A plethora of deployable sensors gathering hyper-accurate data on everything from temperature to topography is yet another revenue generator. Data is valuable and the Forest Walker could generate data sales to various government entities and private concerns.
LiDaR (Light Detection and Ranging) can map topography, perform biomass assessment, comparative soil erosion analysis, etc. It so happens that the Forest Walker’s ability to “see,” to navigate about its surroundings, is LiDaR driven and since it’s already being used, we can get double duty by harvesting that data for later use. By using a laser to send out light pulses and measuring the time it takes for the reflection of those pulses to return, very detailed data sets incrementally build up. Eventually, as enough data about a certain area becomes available, the data becomes useful and valuable.
Forestry concerns, both private and public, often use LiDaR to build 3D models of tree stands to assess the amount of harvest-able lumber in entire sections of forest. Consulting companies offering these services charge anywhere from several hundred to several thousand dollars per square kilometer for such services. A Forest Walker generating such assessments on the fly while performing its other functions is a multi-disciplinary approach to revenue generation.
pH, Soil Moisture, and Cation Exchange Sensing
The Forest Walker is quadrupedal, so there are four contact points to the soil. Why not get a pH data point for every step it takes? We can also gather soil moisture data and cation exchange capacities at unheard of densities because of sampling occurring on the fly during commission of the system’s other duties. No one is going to build a machine to do pH testing of vast tracts of forest soils, but that doesn’t make the data collected from such an endeavor valueless. Since the Forest Walker serves many functions at once, a multitude of data products can add to the return on investment component.
Weather Data
Temperature, humidity, pressure, and even data like evapotranspiration gathered at high densities on broad acre scales have untold value and because the sensors are lightweight and don’t require large power budgets, they come along for the ride at little cost. But, just like the old mantra, “gas, grass, or ass, nobody rides for free”, these sensors provide potential revenue benefits just by them being present.
I’ve touched on just a few data genres here. In fact, the question for universities, governmental bodies, and other institutions becomes, “How much will you pay us to attach your sensor payload to the Forest Walker?”
Noise Suppression
Only you can prevent Metallica filling the surrounds with 120 dB of sound. Easy enough, just turn the car stereo off. But what of a fleet of 50 Forest Walkers operating in the backcountry or near a township? 500? 5000? Each one has a wood chipper, an internal combustion engine, hydraulic pumps, actuators, and more cooling fans than you can shake a stick at. It’s a walking, screaming fire-breathing dragon operating continuously, day and night, twenty-four hours a day, three hundred sixty-five days a year. The sound will negatively affect all living things and that impacts behaviors. Serious engineering consideration and prowess must deliver a silencing blow to the major issue of noise.
It would be foolish to think that a fleet of Forest Walkers could be silent, but if not a major design consideration, then the entire idea is dead on arrival. Townships would not allow them to operate even if they solved the problem of widespread fuel load and neither would governmental entities, and rightly so. Nothing, not man nor beast, would want to be subjected to an eternal, infernal scream even if it were to end within days as the fleet moved further away after consuming what it could. Noise and heat are the only real pollutants of this system; taking noise seriously from the beginning is paramount.
Fire Safety
A “fire-breathing dragon” is not the worst description of the Forest Walker. It eats wood, combusts it at very high temperatures and excretes carbon; and it does so in an extremely flammable environment. Bad mix for one Forest Walker, worse for many. One must take extreme pains to ensure that during normal operation, a Forest Walker could fall over, walk through tinder dry brush, or get pounded into the ground by a meteorite from Krypton and it wouldn’t destroy epic swaths of trees and baby deer. I envision an ultimate test of a prototype to include dowsing it in grain alcohol while it’s wrapped up in toilet paper like a pledge at a fraternity party. If it runs for 72 hours and doesn’t set everything on fire, then maybe outside entities won’t be fearful of something that walks around forests with a constant fire in its belly.
The Wrap
How we think about what can be done with and adjacent to Bitcoin is at least as important as Bitcoin’s economic standing itself. For those who will tell me that this entire idea is without merit, I say, “OK, fine. You can come up with something, too.” What can we plug Bitcoin into that, like a battery, makes something that does not work, work? That’s the lesson I get from this entire exercise. No one was ever going to hire teams of humans to go out and "clean the forest". There's no money in that. The data collection and sales from such an endeavor might provide revenues over the break-even point but investment demands Alpha in this day and age. But, plug Bitcoin into an almost viable system and, voilà! We tip the scales to achieve lift-off.
Let’s face it, we haven’t scratched the surface of Bitcoin’s forcing function on our minds. Not because it’s Bitcoin, but because of what that invention means. The question that pushes me to approach things this way is, “what can we create that one system’s waste is another system’s feedstock?” The Forest Walker system’s only real waste is the conversion of low entropy energy (wood and syngas) into high entropy energy (heat and noise). All other output is beneficial to humanity.
Bitcoin, I believe, is the first product of a new mode of human imagination. An imagination newly forged over the past few millennia of being lied to, stolen from, distracted and otherwise mis-allocated to a black hole of the nonsensical. We are waking up.
What I have presented is not science fiction. Everything I have described here is well within the realm of possibility. The question is one of viability, at least in terms of the detritus of the old world we find ourselves departing from. This system would take a non-trivial amount of time and resources to develop. I think the system would garner extensive long-term contracts from those who have the most to lose from wildfires, the most to gain from hyperaccurate data sets, and, of course, securing the most precious asset in the world. Many may not see it that way, for they seek Alpha and are therefore blind to other possibilities. Others will see only the possibilities; of thinking in a new way, of looking at things differently, and dreaming of what comes next.

@ e3ba5e1a:5e433365
2025-01-13 16:47:27My blog posts and reading material have both been on a decidedly economics-heavy slant recently. The topic today, incentives, squarely falls into the category of economics. However, when I say economics, I’m not talking about “analyzing supply and demand curves.” I’m talking about the true basis of economics: understanding how human beings make decisions in a world of scarcity.
A fair definition of incentive is “a reward or punishment that motivates behavior to achieve a desired outcome.” When most people think about economic incentives, they’re thinking of money. If I offer my son $5 if he washes the dishes, I’m incentivizing certain behavior. We can’t guarantee that he’ll do what I want him to do, but we can agree that the incentive structure itself will guide and ultimately determine what outcome will occur.
The great thing about monetary incentives is how easy they are to talk about and compare. “Would I rather make $5 washing the dishes or $10 cleaning the gutters?” But much of the world is incentivized in non-monetary ways too. For example, using the “punishment” half of the definition above, I might threaten my son with losing Nintendo Switch access if he doesn’t wash the dishes. No money is involved, but I’m still incentivizing behavior.
And there are plenty of incentives beyond our direct control! My son is also incentivized to not wash dishes because it’s boring, or because he has some friends over that he wants to hang out with, or dozens of other things. Ultimately, the conflicting array of different incentive structures placed on him will ultimately determine what actions he chooses to take.
Why incentives matter
A phrase I see often in discussions—whether they are political, parenting, economic, or business—is “if they could just do…” Each time I see that phrase, I cringe a bit internally. Usually, the underlying assumption of the statement is “if people would behave contrary to their incentivized behavior then things would be better.” For example:
- If my kids would just go to bed when I tell them, they wouldn’t be so cranky in the morning.
- If people would just use the recycling bin, we wouldn’t have such a landfill problem.
- If people would just stop being lazy, our team would deliver our project on time.
In all these cases, the speakers are seemingly flummoxed as to why the people in question don’t behave more rationally. The problem is: each group is behaving perfectly rationally.
- The kids have a high time preference, and care more about the joy of staying up now than the crankiness in the morning. Plus, they don’t really suffer the consequences of morning crankiness, their parents do.
- No individual suffers much from their individual contribution to a landfill. If they stopped growing the size of the landfill, it would make an insignificant difference versus the amount of effort they need to engage in to properly recycle.
- If a team doesn’t properly account for the productivity of individuals on a project, each individual receives less harm from their own inaction. Sure, the project may be delayed, company revenue may be down, and they may even risk losing their job when the company goes out of business. But their laziness individually won’t determine the entirety of that outcome. By contrast, they greatly benefit from being lazy by getting to relax at work, go on social media, read a book, or do whatever else they do when they’re supposed to be working.
My point here is that, as long as you ignore the reality of how incentives drive human behavior, you’ll fail at getting the outcomes you want.
If everything I wrote up until now made perfect sense, you understand the premise of this blog post. The rest of it will focus on a bunch of real-world examples to hammer home the point, and demonstrate how versatile this mental model is.
Running a company
Let’s say I run my own company, with myself as the only employee. My personal revenue will be 100% determined by my own actions. If I decide to take Tuesday afternoon off and go fishing, I’ve chosen to lose that afternoon’s revenue. Implicitly, I’ve decided that the enjoyment I get from an afternoon of fishing is greater than the potential revenue. You may think I’m being lazy, but it’s my decision to make. In this situation, the incentive–money–is perfectly aligned with my actions.
Compare this to a typical company/employee relationship. I might have a bank of Paid Time Off (PTO) days, in which case once again my incentives are relatively aligned. I know that I can take off 15 days throughout the year, and I’ve chosen to use half a day for the fishing trip. All is still good.
What about unlimited time off? Suddenly incentives are starting to misalign. I don’t directly pay a price for not showing up to work on Tuesday. Or Wednesday as well, for that matter. I might ultimately be fired for not doing my job, but that will take longer to work its way through the system than simply not making any money for the day taken off.
Compensation overall falls into this misaligned incentive structure. Let’s forget about taking time off. Instead, I work full time on a software project I’m assigned. But instead of using the normal toolchain we’re all used to at work, I play around with a new programming language. I get the fun and joy of playing with new technology, and potentially get to pad my resume a bit when I’m ready to look for a new job. But my current company gets slower results, less productivity, and is forced to subsidize my extracurricular learning.
When a CEO has a bonus structure based on profitability, he’ll do everything he can to make the company profitable. This might include things that actually benefit the company, like improving product quality, reducing internal red tape, or finding cheaper vendors. But it might also include destructive practices, like slashing the R\&D budget to show massive profits this year, in exchange for a catastrophe next year when the next version of the product fails to ship.
Or my favorite example. My parents owned a business when I was growing up. They had a back office where they ran operations like accounting. All of the furniture was old couches from our house. After all, any money they spent on furniture came right out of their paychecks! But in a large corporate environment, each department is generally given a budget for office furniture, a budget which doesn’t roll over year-to-year. The result? Executives make sure to spend the entire budget each year, often buying furniture far more expensive than they would choose if it was their own money.
There are plenty of details you can quibble with above. It’s in a company’s best interest to give people downtime so that they can come back recharged. Having good ergonomic furniture can in fact increase productivity in excess of the money spent on it. But overall, the picture is pretty clear: in large corporate structures, you’re guaranteed to have mismatches between the company’s goals and the incentive structure placed on individuals.
Using our model from above, we can lament how lazy, greedy, and unethical the employees are for doing what they’re incentivized to do instead of what’s right. But that’s simply ignoring the reality of human nature.
Moral hazard
Moral hazard is a situation where one party is incentivized to take on more risk because another party will bear the consequences. Suppose I tell my son when he turns 21 (or whatever legal gambling age is) that I’ll cover all his losses for a day at the casino, but he gets to keep all the winnings.
What do you think he’s going to do? The most logical course of action is to place the largest possible bets for as long as possible, asking me to cover each time he loses, and taking money off the table and into his bank account each time he wins.
But let’s look at a slightly more nuanced example. I go to a bathroom in the mall. As I’m leaving, I wash my hands. It will take me an extra 1 second to turn off the water when I’m done washing. That’s a trivial price to pay. If I don’t turn off the water, the mall will have to pay for many liters of wasted water, benefiting no one. But I won’t suffer any consequences at all.
This is also a moral hazard, but most people will still turn off the water. Why? Usually due to some combination of other reasons such as:
- We’re so habituated to turning off the water that we don’t even consider not turning it off. Put differently, the mental effort needed to not turn off the water is more expensive than the 1 second of time to turn it off.
- Many of us have been brought up with a deep guilt about wasting resources like water. We have an internal incentive structure that makes the 1 second to turn off the water much less costly than the mental anguish of the waste we created.
- We’re afraid we’ll be caught by someone else and face some kind of social repercussions. (Or maybe more than social. Are you sure there isn’t a law against leaving the water tap on?)
Even with all that in place, you may notice that many public bathrooms use automatic water dispensers. Sure, there’s a sanitation reason for that, but it’s also to avoid this moral hazard.
A common denominator in both of these is that the person taking the action that causes the liability (either the gambling or leaving the water on) is not the person who bears the responsibility for that liability (the father or the mall owner). Generally speaking, the closer together the person making the decision and the person incurring the liability are, the smaller the moral hazard.
It’s easy to demonstrate that by extending the casino example a bit. I said it was the father who was covering the losses of the gambler. Many children (though not all) would want to avoid totally bankrupting their parents, or at least financially hurting them. Instead, imagine that someone from the IRS shows up at your door, hands you a credit card, and tells you you can use it at a casino all day, taking home all the chips you want. The money is coming from the government. How many people would put any restriction on how much they spend?
And since we’re talking about the government already…
Government moral hazards
As I was preparing to write this blog post, the California wildfires hit. The discussions around those wildfires gave a huge number of examples of moral hazards. I decided to cherry-pick a few for this post.
The first and most obvious one: California is asking for disaster relief funds from the federal government. That sounds wonderful. These fires were a natural disaster, so why shouldn’t the federal government pitch in and help take care of people?
The problem is, once again, a moral hazard. In the case of the wildfires, California and Los Angeles both had ample actions they could have taken to mitigate the destruction of this fire: better forest management, larger fire department, keeping the water reservoirs filled, and probably much more that hasn’t come to light yet.
If the federal government bails out California, it will be a clear message for the future: your mistakes will be fixed by others. You know what kind of behavior that incentivizes? More risky behavior! Why spend state funds on forest management and extra firefighters—activities that don’t win politicians a lot of votes in general—when you could instead spend it on a football stadium, higher unemployment payments, or anything else, and then let the feds cover the cost of screw-ups.
You may notice that this is virtually identical to the 2008 “too big to fail” bail-outs. Wall Street took insanely risky behavior, reaped huge profits for years, and when they eventually got caught with their pants down, the rest of us bailed them out. “Privatizing profits, socializing losses.”
And here’s the absolute best part of this: I can’t even truly blame either California or Wall Street. (I mean, I do blame them, I think their behavior is reprehensible, but you’ll see what I mean.) In a world where the rules of the game implicitly include the bail-out mentality, you would be harming your citizens/shareholders/investors if you didn’t engage in that risky behavior. Since everyone is on the hook for those socialized losses, your best bet is to maximize those privatized profits.
There’s a lot more to government and moral hazard, but I think these two cases demonstrate the crux pretty solidly. But let’s leave moral hazard behind for a bit and get to general incentivization discussions.
Non-monetary competition
At least 50% of the economics knowledge I have comes from the very first econ course I took in college. That professor was amazing, and had some very colorful stories. I can’t vouch for the veracity of the two I’m about to share, but they definitely drive the point home.
In the 1970s, the US had an oil shortage. To “fix” this problem, they instituted price caps on gasoline, which of course resulted in insufficient gasoline. To “fix” this problem, they instituted policies where, depending on your license plate number, you could only fill up gas on certain days of the week. (Irrelevant detail for our point here, but this just resulted in people filling up their tanks more often, no reduction in gas usage.)
Anyway, my professor’s wife had a friend. My professor described in great detail how attractive this woman was. I’ll skip those details here since this is a PG-rated blog. In any event, she never had any trouble filling up her gas tank any day of the week. She would drive up, be told she couldn’t fill up gas today, bat her eyes at the attendant, explain how helpless she was, and was always allowed to fill up gas.
This is a demonstration of non-monetary compensation. Most of the time in a free market, capitalist economy, people are compensated through money. When price caps come into play, there’s a limit to how much monetary compensation someone can receive. And in that case, people find other ways of competing. Like this woman’s case: through using flirtatious behavior to compensate the gas station workers to let her cheat the rules.
The other example was much more insidious. Santa Monica had a problem: it was predominantly wealthy and white. They wanted to fix this problem, and decided to put in place rent controls. After some time, they discovered that Santa Monica had become wealthier and whiter, the exact opposite of their desired outcome. Why would that happen?
Someone investigated, and ended up interviewing a landlady that demonstrated the reason. She was an older white woman, and admittedly racist. Prior to the rent controls, she would list her apartments in the newspaper, and would be legally obligated to rent to anyone who could afford it. Once rent controls were in place, she took a different tact. She knew that she would only get a certain amount for the apartment, and that the demand for apartments was higher than the supply. That meant she could be picky.
She ended up finding tenants through friends-of-friends. Since it wasn’t an official advertisement, she wasn’t legally required to rent it out if someone could afford to pay. Instead, she got to interview people individually and then make them an offer. Normally, that would have resulted in receiving a lower rental price, but not under rent controls.
So who did she choose? A young, unmarried, wealthy, white woman. It made perfect sense. Women were less intimidating and more likely to maintain the apartment better. Wealthy people, she determined, would be better tenants. (I have no idea if this is true in practice or not, I’m not a landlord myself.) Unmarried, because no kids running around meant less damage to the property. And, of course, white. Because she was racist, and her incentive structure made her prefer whites.
You can deride her for being racist, I won’t disagree with you. But it’s simply the reality. Under the non-rent-control scenario, her profit motive for money outweighed her racism motive. But under rent control, the monetary competition was removed, and she was free to play into her racist tendencies without facing any negative consequences.
Bureaucracy
These were the two examples I remember for that course. But non-monetary compensation pops up in many more places. One highly pertinent example is bureaucracies. Imagine you have a government office, or a large corporation’s acquisition department, or the team that apportions grants at a university. In all these cases, you have a group of people making decisions about handing out money that has no monetary impact on them. If they give to the best qualified recipients, they receive no raises. If they spend the money recklessly on frivolous projects, they face no consequences.
Under such an incentivization scheme, there’s little to encourage the bureaucrats to make intelligent funding decisions. Instead, they’ll be incentivized to spend the money where they recognize non-monetary benefits. This is why it’s so common to hear about expensive meals, gift bags at conferences, and even more inappropriate ways of trying to curry favor with those that hold the purse strings.
Compare that ever so briefly with the purchases made by a small mom-and-pop store like my parents owned. Could my dad take a bribe to buy from a vendor who’s ripping him off? Absolutely he could! But he’d lose more on the deal than he’d make on the bribe, since he’s directly incentivized by the deal itself. It would make much more sense for him to go with the better vendor, save $5,000 on the deal, and then treat himself to a lavish $400 meal to celebrate.
Government incentivized behavior
This post is getting longer in the tooth than I’d intended, so I’ll finish off with this section and make it a bit briefer. Beyond all the methods mentioned above, government has another mechanism for modifying behavior: through directly changing incentives via legislation, regulation, and monetary policy. Let’s see some examples:
- Artificial modification of interest rates encourages people to take on more debt than they would in a free capital market, leading to malinvestment and a consumer debt crisis, and causing the boom-bust cycle we all painfully experience.
- Going along with that, giving tax breaks on interest payments further artificially incentivizes people to take on debt that they wouldn’t otherwise.
- During COVID-19, at some points unemployment benefits were greater than minimum wage, incentivizing people to rather stay home and not work than get a job, leading to reduced overall productivity in the economy and more printed dollars for benefits. In other words, it was a perfect recipe for inflation.
- The tax code gives deductions to “help” people. That might be true, but the real impact is incentivizing people to make decisions they wouldn’t have otherwise. For example, giving out tax deductions on children encourages having more kids. Tax deductions on childcare and preschools incentivizes dual-income households. Whether or not you like the outcomes, it’s clear that it’s government that’s encouraging these outcomes to happen.
- Tax incentives cause people to engage in behavior they wouldn’t otherwise (daycare+working mother, for example).
- Inflation means that the value of your money goes down over time, which encourages people to spend more today, when their money has a larger impact. (Milton Friedman described this as high living.)
Conclusion
The idea here is simple, and fully encapsulated in the title: incentives determine outcomes. If you want to know how to get a certain outcome from others, incentivize them to want that to happen. If you want to understand why people act in seemingly irrational ways, check their incentives. If you’re confused why leaders (and especially politicians) seem to engage in destructive behavior, check their incentives.
We can bemoan these realities all we want, but they are realities. While there are some people who have a solid internal moral and ethical code, and that internal code incentivizes them to behave against their externally-incentivized interests, those people are rare. And frankly, those people are self-defeating. People should take advantage of the incentives around them. Because if they don’t, someone else will.
(If you want a literary example of that last comment, see the horse in Animal Farm.)
How do we improve the world under these conditions? Make sure the incentives align well with the overall goals of society. To me, it’s a simple formula:
- Focus on free trade, value for value, as the basis of a society. In that system, people are always incentivized to provide value to other people.
- Reduce the size of bureaucracies and large groups of all kinds. The larger an organization becomes, the farther the consequences of decisions are from those who make them.
- And since the nature of human beings will be to try and create areas where they can control the incentive systems to their own benefits, make that as difficult as possible. That comes in the form of strict limits on government power, for example.
And even if you don’t want to buy in to this conclusion, I hope the rest of the content was educational, and maybe a bit entertaining!

2025-01-12 21:03:36I’ve been using Notedeck for several months, starting with its extremely early and experimental alpha versions, all the way to its current, more stable alpha releases. The journey has been fascinating, as I’ve had the privilege of watching it evolve from a concept into a functional and promising tool.
In its earliest stages, Notedeck was raw—offering glimpses of its potential but still far from practical for daily use. Even then, the vision behind it was clear: a platform designed to redefine how we interact with Nostr by offering flexibility and power for all users.
I'm very bullish on Notedeck. Why? Because Will Casarin is making it! Duh! 😂
Seriously though, if we’re reimagining the web and rebuilding portions of the Internet, it’s important to recognize the potential of Notedeck. If Nostr is reimagining the web, then Notedeck is reimagining the Nostr client.
Notedeck isn’t just another Nostr app—it’s more a Nostr browser that functions more like an operating system with micro-apps. How cool is that?
Much like how Google's Chrome evolved from being a web browser with a task manager into ChromeOS, a full blown operating system, Notedeck aims to transform how we interact with the Nostr. It goes beyond individual apps, offering a foundation for a fully integrated ecosystem built around Nostr.
As a Nostr evangelist, I love to scream INTEROPERABILITY and tout every application's integrations. Well, Notedeck has the potential to be one of the best platforms to showcase these integrations in entirely new and exciting ways.
Do you want an Olas feed of images? Add the media column.
Do you want a feed of live video events? Add the zap.stream column.
Do you want Nostr Nests or audio chats? Add that column to your Notedeck.
Git? Email? Books? Chat and DMs? It's all possible.
Not everyone wants a super app though, and that’s okay. As with most things in the Nostr ecosystem, flexibility is key. Notedeck gives users the freedom to choose how they engage with it—whether it’s simply following hashtags or managing straightforward feeds. You'll be able to tailor Notedeck to fit your needs, using it as extensively or minimally as you prefer.
Notedeck is designed with a local-first approach, utilizing Nostr content stored directly on your device via the local nostrdb. This will enable a plethora of advanced tools such as search and filtering, the creation of custom feeds, and the ability to develop personalized algorithms across multiple Notedeck micro-applications—all with unparalleled flexibility.
Notedeck also supports multicast. Let's geek out for a second. Multicast is a method of communication where data is sent from one source to multiple destinations simultaneously, but only to devices that wish to receive the data. Unlike broadcast, which sends data to all devices on a network, multicast targets specific receivers, reducing network traffic. This is commonly used for efficient data distribution in scenarios like streaming, conferencing, or large-scale data synchronization between devices.
In a local first world where each device holds local copies of your nostr nodes, and each device transparently syncs with each other on the local network, each node becomes a backup. Your data becomes antifragile automatically. When a node goes down it can resync and recover from other nodes. Even if not all nodes have a complete collection, negentropy can pull down only what is needed from each device. All this can be done without internet.
-Will Casarin
In the context of Notedeck, multicast would allow multiple devices to sync their Nostr nodes with each other over a local network without needing an internet connection. Wild.
Notedeck aims to offer full customization too, including the ability to design and share custom skins, much like Winamp. Users will also be able to create personalized columns and, in the future, share their setups with others. This opens the door for power users to craft tailored Nostr experiences, leveraging their expertise in the protocol and applications. By sharing these configurations as "Starter Decks," they can simplify onboarding and showcase the best of Nostr’s ecosystem.
Nostr’s “Other Stuff” can often be difficult to discover, use, or understand. Many users doesn't understand or know how to use web browser extensions to login to applications. Let's not even get started with nsecbunkers. Notedeck will address this challenge by providing a native experience that brings these lesser-known applications, tools, and content into a user-friendly and accessible interface, making exploration seamless. However, that doesn't mean Notedeck should disregard power users that want to use nsecbunkers though - hint hint.
For anyone interested in watching Nostr be developed live, right before your very eyes, Notedeck’s progress serves as a reminder of what’s possible when innovation meets dedication. The current alpha is already demonstrating its ability to handle complex use cases, and I’m excited to see how it continues to grow as it moves toward a full release later this year.

@ a3c6f928:d45494fb
2025-05-29 11:52:31In a world dominated by noise, distraction, and constant motion, there’s a deeper kind of liberation that many yearn for—spiritual freedom. This is not freedom measured by external factors, but by the stillness within. It’s the kind of freedom that arises when you no longer feel enslaved by ego, fear, or the pursuit of approval.
What Is Spiritual Freedom?
Spiritual freedom is the ability to live in alignment with your highest truth. It means being free from the illusions of control, unshackled from the burdens of regret, and connected to something greater than yourself—whether that’s God, the universe, or your own divine essence.
It is peace that doesn’t depend on circumstance. It is joy that isn’t based on possession. It’s knowing who you are beyond the labels, titles, and roles you play.
Signs You’re Seeking Spiritual Freedom
You feel unfulfilled despite material success
You’re questioning your deeper purpose or path
You long for peace that outlasts the highs and lows
You’re becoming more drawn to stillness, simplicity, or presence
The Path to Inner Liberation
-
Let Go of the Ego: Ego thrives on identity, comparison, and control. Spiritual freedom comes when you stop living to protect or promote a false self.
-
Live in the Now: Freedom is found in presence. Not in what happened yesterday or what might come tomorrow, but in this exact breath.
-
Seek Connection Over Control: The more we try to control life, the more trapped we feel. Surrender doesn’t mean giving up—it means trusting a higher order and flowing with it.
-
Forgive and Release: Grudges and guilt are spiritual chains. Letting go of what weighs down your spirit is one of the most liberating things you can do.
-
Return to Love: At the heart of all spiritual freedom is love—not romantic love, but divine love, unconditional love, the kind that expands you rather than limits you.
Why It Matters
In chasing external freedom, we often forget that without inner peace, nothing ever feels free. Spiritual freedom is what makes outer success meaningful. It’s what allows us to face life’s storms without being broken by them.
“You find peace not by rearranging the circumstances of your life, but by realizing who you are at the deepest level.” — Eckhart Tolle
True freedom is not out there. It’s already within you—waiting to be remembered.

- 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.
GM Nostr.

2025-05-28 23:24:05I’ve spent years chasing the promise of freedom.\ In startups. In faith communities. In movements that claimed to be for the people.
And yet — so often, that promise felt just out of reach.\ Conditional. Corporate. Sanitized.\ A freedom with fine print.
But here —\ Here in the thick of Bitcoin 2025, on Nostr, among misfits and builders and signal-bringers —\ something is alive.
It’s not a platform.\ It’s not a marketing strategy.\ It’s not another app promising to “empower” you while locking down your data and selling you out.
It’s freedom rooted in architecture.\ Decentralization not just as a buzzword —\ but as an expression of conviction.
A kind of freedom you can feel in your body:
-
When you zap someone’s words because they moved you — not because an algorithm told you to.
-
When your identity is yours — keys, not credentials.
-
When no one can delete your story because you control the server, or because there is no server — just the relay of your choosing.
This isn’t utopia.\ There are egos. There’s noise. There’s still posturing.\ But it’s different.\ The center of gravity has shifted.
We’re no longer begging institutions to notice us.\ We’re building outside their jurisdiction.
And for the first time in a long time,\ freedom feels close.\ Tangible.\ Joyful.\ Alive.
This isn’t just about tech.\ It’s about trust.\ It’s about choosing to show up —\ to build\ to write\ to signal\ to keep going.
Even when it’s hard.\ Even when no one claps.
Because real freedom doesn’t come from being noticed.\ It comes from being sovereign.
And that’s something no one can take from me again.

Donald Trump Jr. Unveils $2.5B Bitcoin Push: “We’re Going to the Moon”In an interview at the Bitcoin 2025 Conference today, Rumble Founder and CEO Chris Pavlovski sat down with Don Trump Jr. to talk free speech, Bitcoin, and a seismic shift in the financial system—fueled by the current administration’s pro-crypto stance.

“I wasn’t an early adopter like so many people in the room who were here in 2012,” Trump Jr. admitted. “We were real estate guys. Finance was always easy for us.”
Trump Jr. revealed that TMTG and Truth Social are forming a Bitcoin treasury to the tune of $2.5 billion—a move he called “a pretty big deal.” The announcement comes alongside new partnerships, including one with mining giant Hut 8, and the launch of a new group focused on building American Bitcoin reserves.
“We’re seriously on crypto—we’re seriously on Bitcoin,” Trump Jr. emphasized. “We’re in three major deals. I believe we’re at the beginning of what will be the future of finance. And the opportunity is massive.”
Chris Pavlovski agreed: “We weren’t a Bitcoin company to start off with—we were a free speech company. But I almost think we’re at that ‘all of a sudden’ moment. The floodgates are opening.”

The pair drew comparisons between Bitcoin and Rumble, describing both as targets of relentless media and regulatory pressure. “Bitcoin has had things thrown at it—laws, attacks,” said Pavlovski. “Same with Rumble. But we’re in an environment now where the administration is extremely pro-crypto and pro-Bitcoin.”
“The latest adopters are going to fare the worst,” Trump Jr. warned. “It’s the future of finance. I’m so excited to see the administration stepping up.”
Rumble’s Bitcoin strategy, including its move to build reserves, was directly inspired by this shift. “It gave me all kinds of confidence that the administration would do all the right things,” Pavlovski said.
“Trump gets this stuff. He gets it quick,” Trump Jr. closed. “We’re going to the moon, guys. Stay in. Stay strong.”

GameStop Buys $513 Million Worth of BitcoinVideo game retailer GameStop has purchased 4,710 Bitcoin worth approximately $513 million, marking another major corporate entry into Bitcoin treasury holdings as the trend of companies adding Bitcoin to their balance sheets accelerates in 2025.
The company announced the acquisition via X on Wednesday but did not disclose specific details about when the purchases were made or the average price paid per coin. The move follows GameStop’s March announcement of plans to pursue a Bitcoin treasury strategy, which included a $1.3 billion convertible senior notes offering to fund Bitcoin purchases.

GAMESTOP PURCHASED 4,710 #BITCOIN pic.twitter.com/fDH9ctZJVP
— Bitcoin Magazine (@BitcoinMagazine) May 28, 2025
GameStop’s Bitcoin acquisition represents a strategic shift in corporate treasury management, following the playbook established by companies like Strategy.
The purchase comes amid a surge in corporate Bitcoin adoption, with over 50 public companies announcing Bitcoin treasury programs in the first five months of 2025. Recent entrants include 21 Capital, Strive, H100 Group and more.
The announcement pushed GameStop’s shares up 4.4% in pre-market trading, while Bitcoin traded near $108,900. The company reported $4.78 billion in cash and marketable securities as of February 1, suggesting this Bitcoin investment represents approximately 10.7% of its liquid assets.
The move follows similar treasury diversification strategies by other major corporations, including Tesla’s $1.25 billion Bitcoin holding and recent announcements from Trump Media and Technology Group of plans to raise $2.5 billion for Bitcoin purchases.
At press time, Bitcoin trades at $108,900, down 0.68% over the past 24 hours, as the market processes this significant institutional development and its implications for broader corporate adoption of Bitcoin as a treasury asset.

2024-12-31 20:18:59Scuttlebutt foi iniciado em maio de 2014 por Dominic Tarr ( dominictarr ) como uma rede social alternativa off-line, primeiro para convidados, que permite aos usuários obter controle total de seus dados e privacidade. Secure Scuttlebutt (ssb) foi lançado pouco depois, o que coloca a privacidade em primeiro plano com mais recursos de criptografia.
Se você está se perguntando de onde diabos veio o nome Scuttlebutt:
Este termo do século 19 para uma fofoca vem do Scuttlebutt náutico: “um barril de água mantido no convés, com um buraco para uma xícara”. A gíria náutica vai desde o hábito dos marinheiros de se reunir pelo boato até a fofoca, semelhante à fofoca do bebedouro.
Marinheiros se reunindo em torno da rixa. ( fonte )
Dominic descobriu o termo boato em um artigo de pesquisa que leu.
Em sistemas distribuídos, fofocar é um processo de retransmissão de mensagens ponto a ponto; as mensagens são disseminadas de forma análoga ao “boca a boca”.
Secure Scuttlebutt é um banco de dados de feeds imutáveis apenas para acréscimos, otimizado para replicação eficiente para protocolos ponto a ponto. Cada usuário tem um log imutável somente para acréscimos no qual eles podem gravar. Eles gravam no log assinando mensagens com sua chave privada. Pense em um feed de usuário como seu próprio diário de bordo, como um diário de bordo (ou diário do capitão para os fãs de Star Trek), onde eles são os únicos autorizados a escrever nele, mas têm a capacidade de permitir que outros amigos ou colegas leiam ao seu diário de bordo, se assim o desejarem.
Cada mensagem possui um número de sequência e a mensagem também deve fazer referência à mensagem anterior por seu ID. O ID é um hash da mensagem e da assinatura. A estrutura de dados é semelhante à de uma lista vinculada. É essencialmente um log somente de acréscimo de JSON assinado. Cada item adicionado a um log do usuário é chamado de mensagem.
Os logs do usuário são conhecidos como feed e um usuário pode seguir os feeds de outros usuários para receber suas atualizações. Cada usuário é responsável por armazenar seu próprio feed. Quando Alice assina o feed de Bob, Bob baixa o log de feed de Alice. Bob pode verificar se o registro do feed realmente pertence a Alice verificando as assinaturas. Bob pode verificar as assinaturas usando a chave pública de Alice.
Estrutura de alto nível de um feed
Pubs são servidores de retransmissão conhecidos como “super peers”. Pubs conectam usuários usuários e atualizações de fofocas a outros usuários conectados ao Pub. Um Pub é análogo a um pub da vida real, onde as pessoas vão para se encontrar e se socializar. Para ingressar em um Pub, o usuário deve ser convidado primeiro. Um usuário pode solicitar um código de convite de um Pub; o Pub simplesmente gerará um novo código de convite, mas alguns Pubs podem exigir verificação adicional na forma de verificação de e-mail ou, com alguns Pubs, você deve pedir um código em um fórum público ou chat. Pubs também podem mapear aliases de usuário, como e-mails ou nome de usuário, para IDs de chave pública para facilitar os pares de referência.
Depois que o Pub enviar o código de convite ao usuário, o usuário resgatará o código, o que significa que o Pub seguirá o usuário, o que permite que o usuário veja as mensagens postadas por outros membros do Pub, bem como as mensagens de retransmissão do Pub pelo usuário a outros membros do Pub.
Além de retransmitir mensagens entre pares, os Pubs também podem armazenar as mensagens. Se Alice estiver offline e Bob transmitir atualizações de feed, Alice perderá a atualização. Se Alice ficar online, mas Bob estiver offline, não haverá como ela buscar o feed de Bob. Mas com um Pub, Alice pode buscar o feed no Pub mesmo se Bob estiver off-line porque o Pub está armazenando as mensagens. Pubs são úteis porque assim que um colega fica online, ele pode sincronizar com o Pub para receber os feeds de seus amigos potencialmente offline.
Um usuário pode, opcionalmente, executar seu próprio servidor Pub e abri-lo ao público ou permitir que apenas seus amigos participem, se assim o desejarem. Eles também podem ingressar em um Pub público. Aqui está uma lista de Pubs públicos em que todos podem participar . Explicaremos como ingressar em um posteriormente neste guia. Uma coisa importante a observar é que o Secure Scuttlebutt em uma rede social somente para convidados significa que você deve ser “puxado” para entrar nos círculos sociais. Se você responder às mensagens, os destinatários não serão notificados, a menos que estejam seguindo você de volta. O objetivo do SSB é criar “ilhas” isoladas de redes pares, ao contrário de uma rede pública onde qualquer pessoa pode enviar mensagens a qualquer pessoa.

Patchwork - Uma GUI SSB (Descontinuado)
Patchwork é o aplicativo de mensagens e compartilhamento descentralizado construído em cima do SSB . O protocolo scuttlebutt em si não mantém um conjunto de feeds nos quais um usuário está interessado, então um cliente é necessário para manter uma lista de feeds de pares em que seu respectivo usuário está interessado e seguindo.
Fonte: scuttlebutt.nz
Quando você instala e executa o Patchwork, você só pode ver e se comunicar com seus pares em sua rede local. Para acessar fora de sua LAN, você precisa se conectar a um Pub. Um pub é apenas para convidados e eles retransmitem mensagens entre você e seus pares fora de sua LAN e entre outros Pubs.
Lembre-se de que você precisa seguir alguém para receber mensagens dessa pessoa. Isso reduz o envio de mensagens de spam para os usuários. Os usuários só veem as respostas das pessoas que seguem. Os dados são sincronizados no disco para funcionar offline, mas podem ser sincronizados diretamente com os pares na sua LAN por wi-fi ou bluetooth.
Patchbay - Uma GUI Alternativa
Patchbay é um cliente de fofoca projetado para ser fácil de modificar e estender. Ele usa o mesmo banco de dados que Patchwork e Patchfoo , então você pode facilmente dar uma volta com sua identidade existente.
Planetary - GUI para IOS
Planetary é um app com pubs pré-carregados para facilitar integração.
Manyverse - GUI para Android
Manyverse é um aplicativo de rede social com recursos que você esperaria: posts, curtidas, perfis, mensagens privadas, etc. Mas não está sendo executado na nuvem de propriedade de uma empresa, em vez disso, as postagens de seus amigos e todos os seus dados sociais vivem inteiramente em seu telefone .

@ e97aaffa:2ebd765d
2024-12-31 16:47:12Último dia do ano, momento para tirar o pó da bola de cristal, para fazer reflexões, previsões e desejos para o próximo ano e seguintes.
Ano após ano, o Bitcoin evoluiu, foi ultrapassando etapas, tornou-se cada vez mais mainstream. Está cada vez mais difícil fazer previsões sobre o Bitcoin, já faltam poucas barreiras a serem ultrapassadas e as que faltam são altamente complexas ou tem um impacto profundo no sistema financeiro ou na sociedade. Estas alterações profundas tem que ser realizadas lentamente, porque uma alteração rápida poderia resultar em consequências terríveis, poderia provocar um retrocesso.
Código do Bitcoin
No final de 2025, possivelmente vamos ter um fork, as discussões sobre os covenants já estão avançadas, vão acelerar ainda mais. Já existe um consenso relativamente alto, a favor dos covenants, só falta decidir que modelo será escolhido. Penso que até ao final do ano será tudo decidido.
Depois dos covenants, o próximo foco será para a criptografia post-quantum, que será o maior desafio que o Bitcoin enfrenta. Criar uma criptografia segura e que não coloque a descentralização em causa.
Espero muito de Ark, possivelmente a inovação do ano, gostaria de ver o Nostr a furar a bolha bitcoinheira e que o Cashu tivesse mais reconhecimento pelos bitcoiners.
Espero que surjam avanços significativos no BitVM2 e BitVMX.
Não sei o que esperar das layer 2 de Bitcoin, foram a maior desilusão de 2024. Surgiram com muita força, mas pouca coisa saiu do papel, foi uma mão cheia de nada. Uma parte dos projetos caiu na tentação da shitcoinagem, na criação de tokens, que tem um único objetivo, enriquecer os devs e os VCs.
Se querem ser levados a sério, têm que ser sérios.
“À mulher de César não basta ser honesta, deve parecer honesta”
Se querem ter o apoio dos bitcoiners, sigam o ethos do Bitcoin.
Neste ponto a atitude do pessoal da Ark é exemplar, em vez de andar a chorar no Twitter para mudar o código do Bitcoin, eles colocaram as mãos na massa e criaram o protocolo. É claro que agora está meio “coxo”, funciona com uma multisig ou com os covenants na Liquid. Mas eles estão a criar um produto, vão demonstrar ao mercado que o produto é bom e útil. Com a adoção, a comunidade vai perceber que o Ark necessita dos covenants para melhorar a interoperabilidade e a soberania.
É este o pensamento certo, que deveria ser seguido pelos restantes e futuros projetos. É seguir aquele pensamento do J.F. Kennedy:
“Não perguntem o que é que o vosso país pode fazer por vocês, perguntem o que é que vocês podem fazer pelo vosso país”
Ou seja, não fiquem à espera que o bitcoin mude, criem primeiro as inovações/tecnologia, ganhem adoção e depois demonstrem que a alteração do código camada base pode melhorar ainda mais o vosso projeto. A necessidade é que vai levar a atualização do código.
Reservas Estratégicas de Bitcoin
Bancos centrais
Com a eleição de Trump, emergiu a ideia de uma Reserva Estratégia de Bitcoin, tornou este conceito mainstream. Foi um pivot, a partir desse momento, foram enumerados os políticos de todo o mundo a falar sobre o assunto.
A Senadora Cynthia Lummis foi mais além e propôs um programa para adicionar 200 mil bitcoins à reserva ao ano, até 1 milhão de Bitcoin. Só que isto está a criar uma enorme expectativa na comunidade, só que pode resultar numa enorme desilusão. Porque no primeiro ano, o Trump em vez de comprar os 200 mil, pode apenas adicionar na reserva, os 198 mil que o Estado já tem em sua posse. Se isto acontecer, possivelmente vai resultar numa forte queda a curto prazo. Na minha opinião os bancos centrais deveriam seguir o exemplo de El Salvador, fazer um DCA diário.
Mais que comprar bitcoin, para mim, o mais importante é a criação da Reserva, é colocar o Bitcoin ao mesmo nível do ouro, o impacto para o resto do mundo será tremendo, a teoria dos jogos na sua plenitude. Muitos outros bancos centrais vão ter que comprar, para não ficarem atrás, além disso, vai transmitir uma mensagem à generalidade da população, que o Bitcoin é “afinal é algo seguro, com valor”.
Mas não foi Trump que iniciou esta teoria dos jogos, mas sim foi a primeira vítima dela. É o próprio Trump que o admite, que os EUA necessitam da reserva para não ficar atrás da China. Além disso, desde que os EUA utilizaram o dólar como uma arma, com sanção contra a Rússia, surgiram boatos de que a Rússia estaria a utilizar o Bitcoin para transações internacionais. Que foram confirmados recentemente, pelo próprio governo russo. Também há poucos dias, ainda antes deste reconhecimento público, Putin elogiou o Bitcoin, ao reconhecer que “Ninguém pode proibir o bitcoin”, defendendo como uma alternativa ao dólar. A narrativa está a mudar.
Já existem alguns países com Bitcoin, mas apenas dois o fizeram conscientemente (El Salvador e Butão), os restantes têm devido a apreensões. Hoje são poucos, mas 2025 será o início de uma corrida pelos bancos centrais. Esta corrida era algo previsível, o que eu não esperava é que acontecesse tão rápido.
Empresas
A criação de reservas estratégicas não vai ficar apenas pelos bancos centrais, também vai acelerar fortemente nas empresas em 2025.
Mas as empresas não vão seguir a estratégia do Saylor, vão comprar bitcoin sem alavancagem, utilizando apenas os tesouros das empresas, como uma proteção contra a inflação. Eu não sou grande admirador do Saylor, prefiro muito mais, uma estratégia conservadora, sem qualquer alavancagem. Penso que as empresas vão seguir a sugestão da BlackRock, que aconselha um alocações de 1% a 3%.
Penso que 2025, ainda não será o ano da entrada das 6 magníficas (excepto Tesla), será sobretudo empresas de pequena e média dimensão. As magníficas ainda tem uma cota muito elevada de shareholders com alguma idade, bastante conservadores, que têm dificuldade em compreender o Bitcoin, foi o que aconteceu recentemente com a Microsoft.
Também ainda não será em 2025, talvez 2026, a inclusão nativamente de wallet Bitcoin nos sistema da Apple Pay e da Google Pay. Seria um passo gigante para a adoção a nível mundial.
ETFs
Os ETFs para mim são uma incógnita, tenho demasiadas dúvidas, como será 2025. Este ano os inflows foram superiores a 500 mil bitcoins, o IBIT foi o lançamento de ETF mais bem sucedido da história. O sucesso dos ETFs, deve-se a 2 situações que nunca mais se vão repetir. O mercado esteve 10 anos à espera pela aprovação dos ETFs, a procura estava reprimida, isso foi bem notório nos primeiros meses, os inflows foram brutais.
Também se beneficiou por ser um mercado novo, não existia orderbook de vendas, não existia um mercado interno, praticamente era só inflows. Agora o mercado já estabilizou, a maioria das transações já são entre clientes dos próprios ETFs. Agora só uma pequena percentagem do volume das transações diárias vai resultar em inflows ou outflows.
Estes dois fenómenos nunca mais se vão repetir, eu não acredito que o número de inflows em BTC supere os número de 2024, em dólares vai superar, mas em btc não acredito que vá superar.
Mas em 2025 vão surgir uma infindável quantidade de novos produtos, derivativos, novos ETFs de cestos com outras criptos ou cestos com ativos tradicionais. O bitcoin será adicionado em produtos financeiros já existentes no mercado, as pessoas vão passar a deter bitcoin, sem o saberem.
Com o fim da operação ChokePoint 2.0, vai surgir uma nova onda de adoção e de produtos financeiros. Possivelmente vamos ver bancos tradicionais a disponibilizar produtos ou serviços de custódia aos seus clientes.
Eu adoraria ver o crescimento da adoção do bitcoin como moeda, só que a regulamentação não vai ajudar nesse processo.
Preço
Eu acredito que o topo deste ciclo será alcançado no primeiro semestre, posteriormente haverá uma correção. Mas desta vez, eu acredito que a correção será muito menor que as anteriores, inferior a 50%, esta é a minha expectativa. Espero estar certo.
Stablecoins de dólar
Agora saindo um pouco do universo do Bitcoin, acho importante destacar as stablecoins.
No último ciclo, eu tenho dividido o tempo, entre continuar a estudar o Bitcoin e estudar o sistema financeiro, as suas dinâmicas e o comportamento humano. Isto tem sido o meu foco de reflexão, imaginar a transformação que o mundo vai sofrer devido ao padrão Bitcoin. É uma ilusão acreditar que a transição de um padrão FIAT para um padrão Bitcoin vai ser rápida, vai existir um processo transitório que pode demorar décadas.
Com a re-entrada de Trump na Casa Branca, prometendo uma política altamente protecionista, vai provocar uma forte valorização do dólar, consequentemente as restantes moedas do mundo vão derreter. Provocando uma inflação generalizada, gerando uma corrida às stablecoins de dólar nos países com moedas mais fracas. Trump vai ter uma política altamente expansionista, vai exportar dólares para todo o mundo, para financiar a sua própria dívida. A desigualdade entre os pobres e ricos irá crescer fortemente, aumentando a possibilidade de conflitos e revoltas.
“Casa onde não há pão, todos ralham e ninguém tem razão”
Será mais lenha, para alimentar a fogueira, vai gravar os conflitos geopolíticos já existentes, ficando as sociedade ainda mais polarizadas.
Eu acredito que 2025, vai haver um forte crescimento na adoção das stablecoins de dólares, esse forte crescimento vai agravar o problema sistémico que são as stablecoins. Vai ser o início do fim das stablecoins, pelo menos, como nós conhecemos hoje em dia.
Problema sistémico
O sistema FIAT não nasceu de um dia para outro, foi algo que foi construído organicamente, ou seja, foi evoluindo ao longo dos anos, sempre que havia um problema/crise, eram criadas novas regras ou novas instituições para minimizar os problemas. Nestes quase 100 anos, desde os acordos de Bretton Woods, a evolução foram tantas, tornaram o sistema financeiro altamente complexo, burocrático e nada eficiente.
Na prática é um castelo de cartas construído sobre outro castelo de cartas e que por sua vez, foi construído sobre outro castelo de cartas.
As stablecoins são um problema sistémico, devido às suas reservas em dólares e o sistema financeiro não está preparado para manter isso seguro. Com o crescimento das reservas ao longo dos anos, foi se agravando o problema.
No início a Tether colocava as reservas em bancos comerciais, mas com o crescimento dos dólares sob gestão, criou um problema nos bancos comerciais, devido à reserva fracionária. Essas enormes reservas da Tether estavam a colocar em risco a própria estabilidade dos bancos.
A Tether acabou por mudar de estratégia, optou por outros ativos, preferencialmente por títulos do tesouro/obrigações dos EUA. Só que a Tether continua a crescer e não dá sinais de abrandamento, pelo contrário.
Até o próprio mundo cripto, menosprezava a gravidade do problema da Tether/stablecoins para o resto do sistema financeiro, porque o marketcap do cripto ainda é muito pequeno. É verdade que ainda é pequeno, mas a Tether não o é, está no top 20 dos maiores detentores de títulos do tesouros dos EUA e está ao nível dos maiores bancos centrais do mundo. Devido ao seu tamanho, está a preocupar os responsáveis/autoridades/reguladores dos EUA, pode colocar em causa a estabilidade do sistema financeiro global, que está assente nessas obrigações.
Os títulos do tesouro dos EUA são o colateral mais utilizado no mundo, tanto por bancos centrais, como por empresas, é a charneira da estabilidade do sistema financeiro. Os títulos do tesouro são um assunto muito sensível. Na recente crise no Japão, do carry trade, o Banco Central do Japão tentou minimizar a desvalorização do iene através da venda de títulos dos EUA. Esta operação, obrigou a uma viagem de emergência, da Secretaria do Tesouro dos EUA, Janet Yellen ao Japão, onde disponibilizou liquidez para parar a venda de títulos por parte do Banco Central do Japão. Essa forte venda estava desestabilizando o mercado.
Os principais detentores de títulos do tesouros são institucionais, bancos centrais, bancos comerciais, fundo de investimento e gestoras, tudo administrado por gestores altamente qualificados, racionais e que conhecem a complexidade do mercado de obrigações.
O mundo cripto é seu oposto, é naife com muita irracionalidade e uma forte pitada de loucura, na sua maioria nem faz a mínima ideia como funciona o sistema financeiro. Essa irracionalidade pode levar a uma “corrida bancária”, como aconteceu com o UST da Luna, que em poucas horas colapsou o projeto. Em termos de escala, a Luna ainda era muito pequena, por isso, o problema ficou circunscrito ao mundo cripto e a empresas ligadas diretamente ao cripto.
Só que a Tether é muito diferente, caso exista algum FUD, que obrigue a Tether a desfazer-se de vários biliões ou dezenas de biliões de dólares em títulos num curto espaço de tempo, poderia provocar consequências terríveis em todo o sistema financeiro. A Tether é grande demais, é já um problema sistémico, que vai agravar-se com o crescimento em 2025.
Não tenham dúvidas, se existir algum problema, o Tesouro dos EUA vai impedir a venda dos títulos que a Tether tem em sua posse, para salvar o sistema financeiro. O problema é, o que vai fazer a Tether, se ficar sem acesso às venda das reservas, como fará o redeem dos dólares?
Como o crescimento do Tether é inevitável, o Tesouro e o FED estão com um grande problema em mãos, o que fazer com o Tether?
Mas o problema é que o atual sistema financeiro é como um curto cobertor: Quanto tapas a cabeça, destapas os pés; Ou quando tapas os pés, destapas a cabeça. Ou seja, para resolver o problema da guarda reservas da Tether, vai criar novos problemas, em outros locais do sistema financeiro e assim sucessivamente.
Conta mestre
Uma possível solução seria dar uma conta mestre à Tether, dando o acesso direto a uma conta no FED, semelhante à que todos os bancos comerciais têm. Com isto, a Tether deixaria de necessitar os títulos do tesouro, depositando o dinheiro diretamente no banco central. Só que isto iria criar dois novos problemas, com o Custodia Bank e com o restante sistema bancário.
O Custodia Bank luta há vários anos contra o FED, nos tribunais pelo direito a ter licença bancária para um banco com full-reserves. O FED recusou sempre esse direito, com a justificativa que esse banco, colocaria em risco toda a estabilidade do sistema bancário existente, ou seja, todos os outros bancos poderiam colapsar. Perante a existência em simultâneo de bancos com reserva fracionária e com full-reserves, as pessoas e empresas iriam optar pelo mais seguro. Isso iria provocar uma corrida bancária, levando ao colapso de todos os bancos com reserva fracionária, porque no Custodia Bank, os fundos dos clientes estão 100% garantidos, para qualquer valor. Deixaria de ser necessário limites de fundos de Garantia de Depósitos.
Eu concordo com o FED nesse ponto, que os bancos com full-reserves são uma ameaça a existência dos restantes bancos. O que eu discordo do FED, é a origem do problema, o problema não está nos bancos full-reserves, mas sim nos que têm reserva fracionária.
O FED ao conceder uma conta mestre ao Tether, abre um precedente, o Custodia Bank irá o aproveitar, reclamando pela igualdade de direitos nos tribunais e desta vez, possivelmente ganhará a sua licença.
Ainda há um segundo problema, com os restantes bancos comerciais. A Tether passaria a ter direitos similares aos bancos comerciais, mas os deveres seriam muito diferentes. Isto levaria os bancos comerciais aos tribunais para exigir igualdade de tratamento, é uma concorrência desleal. Isto é o bom dos tribunais dos EUA, são independentes e funcionam, mesmo contra o estado. Os bancos comerciais têm custos exorbitantes devido às políticas de compliance, como o KYC e AML. Como o governo não vai querer aliviar as regras, logo seria a Tether, a ser obrigada a fazer o compliance dos seus clientes.
A obrigação do KYC para ter stablecoins iriam provocar um terramoto no mundo cripto.
Assim, é pouco provável que seja a solução para a Tether.
FED
Só resta uma hipótese, ser o próprio FED a controlar e a gerir diretamente as stablecoins de dólar, nacionalizado ou absorvendo as existentes. Seria uma espécie de CBDC. Isto iria provocar um novo problema, um problema diplomático, porque as stablecoins estão a colocar em causa a soberania monetária dos outros países. Atualmente as stablecoins estão um pouco protegidas porque vivem num limbo jurídico, mas a partir do momento que estas são controladas pelo governo americano, tudo muda. Os países vão exigir às autoridades americanas medidas que limitem o uso nos seus respectivos países.
Não existe uma solução boa, o sistema FIAT é um castelo de cartas, qualquer carta que se mova, vai provocar um desmoronamento noutro local. As autoridades não poderão adiar mais o problema, terão que o resolver de vez, senão, qualquer dia será tarde demais. Se houver algum problema, vão colocar a responsabilidade no cripto e no Bitcoin. Mas a verdade, a culpa é inteiramente dos políticos, da sua incompetência em resolver os problemas a tempo.
Será algo para acompanhar futuramente, mas só para 2026, talvez…
É curioso, há uns anos pensava-se que o Bitcoin seria a maior ameaça ao sistema ao FIAT, mas afinal, a maior ameaça aos sistema FIAT é o próprio FIAT(stablecoins). A ironia do destino.
Isto é como uma corrida, o Bitcoin é aquele atleta que corre ao seu ritmo, umas vezes mais rápido, outras vezes mais lento, mas nunca pára. O FIAT é o atleta que dá tudo desde da partida, corre sempre em velocidade máxima. Só que a vida e o sistema financeiro não é uma prova de 100 metros, mas sim uma maratona.
Europa
2025 será um ano desafiante para todos europeus, sobretudo devido à entrada em vigor da regulamentação (MiCA). Vão começar a sentir na pele a regulamentação, vão agravar-se os problemas com os compliance, problemas para comprovar a origem de fundos e outras burocracias. Vai ser lindo.
O Travel Route passa a ser obrigatório, os europeus serão obrigados a fazer o KYC nas transações. A Travel Route é uma suposta lei para criar mais transparência, mas prática, é uma lei de controle, de monitorização e para limitar as liberdades individuais dos cidadãos.
O MiCA também está a colocar problemas nas stablecoins de Euro, a Tether para já preferiu ficar de fora da europa. O mais ridículo é que as novas regras obrigam os emissores a colocar 30% das reservas em bancos comerciais. Os burocratas europeus não compreendem que isto coloca em risco a estabilidade e a solvência dos próprios bancos, ficam propensos a corridas bancárias.
O MiCA vai obrigar a todas as exchanges a estar registadas em solo europeu, ficando vulnerável ao temperamento dos burocratas. Ainda não vai ser em 2025, mas a UE vai impor políticas de controle de capitais, é inevitável, as exchanges serão obrigadas a usar em exclusividade stablecoins de euro, as restantes stablecoins serão deslistadas.
Todas estas novas regras do MiCA, são extremamente restritas, não é para garantir mais segurança aos cidadãos europeus, mas sim para garantir mais controle sobre a população. A UE está cada vez mais perto da autocracia, do que da democracia. A minha única esperança no horizonte, é que o sucesso das políticas cripto nos EUA, vai obrigar a UE a recuar e a aligeirar as regras, a teoria dos jogos é implacável. Mas esse recuo, nunca acontecerá em 2025, vai ser um longo período conturbado.
Recessão
Os mercados estão todos em máximos históricos, isto não é sustentável por muito tempo, suspeito que no final de 2025 vai acontecer alguma correção nos mercados. A queda só não será maior, porque os bancos centrais vão imprimir dinheiro, muito dinheiro, como se não houvesse amanhã. Vão voltar a resolver os problemas com a injeção de liquidez na economia, é empurrar os problemas com a barriga, em de os resolver. Outra vez o efeito Cantillon.
Será um ano muito desafiante a nível político, onde o papel dos políticos será fundamental. A crise política na França e na Alemanha, coloca a UE órfã, sem um comandante ao leme do navio. 2025 estará condicionado pelas eleições na Alemanha, sobretudo no resultado do AfD, que podem colocar em causa a propriedade UE e o euro.
Possivelmente, só o fim da guerra poderia minimizar a crise, algo que é muito pouco provável acontecer.
Em Portugal, a economia parece que está mais ou menos equilibrada, mas começam a aparecer alguns sinais preocupantes. Os jogos de sorte e azar estão em máximos históricos, batendo o recorde de 2014, época da grande crise, não é um bom sinal, possivelmente já existe algum desespero no ar.
A Alemanha é o motor da Europa, quanto espirra, Portugal constipa-se. Além do problema da Alemanha, a Espanha também está à beira de uma crise, são os países que mais influenciam a economia portuguesa.
Se existir uma recessão mundial, terá um forte impacto no turismo, que é hoje em dia o principal motor de Portugal.
Brasil
Brasil é algo para acompanhar em 2025, sobretudo a nível macro e a nível político. Existe uma possibilidade de uma profunda crise no Brasil, sobretudo na sua moeda. O banco central já anda a queimar as reservas para minimizar a desvalorização do Real.
Sem mudanças profundas nas políticas fiscais, as reservas vão se esgotar. As políticas de controle de capitais são um cenário plausível, será interesse de acompanhar, como o governo irá proceder perante a existência do Bitcoin e stablecoins. No Brasil existe um forte adoção, será um bom case study, certamente irá repetir-se em outros países num futuro próximo.
Os próximos tempos não serão fáceis para os brasileiros, especialmente para os que não têm Bitcoin.
Blockchain
Em 2025, possivelmente vamos ver os primeiros passos da BlackRock para criar a primeira bolsa de valores, exclusivamente em blockchain. Eu acredito que a BlackRock vai criar uma própria blockchain, toda controlada por si, onde estarão os RWAs, para fazer concorrência às tradicionais bolsas de valores. Será algo interessante de acompanhar.
Estas são as minhas previsões, eu escrevi isto muito em cima do joelho, certamente esqueci-me de algumas coisas, se for importante acrescentarei nos comentários. A maioria das previsões só acontecerá após 2025, mas fica aqui a minha opinião.
Isto é apenas a minha opinião, Don’t Trust, Verify!

2025-05-29 10:01:10Ed Suman, a 67-year-old retired artist who helped create large sculptures like Jeff Koons’ Balloon Dog, reportedly lost his entire life savings — over $2M in digital assets — in a sophisticated scam.
The incident is believed to be tied to the major data breach at Coinbase, one of the world’s largest digital asset exchanges.
Suman’s story is part of a bigger wave of attacks on digital asset holders using stolen personal info, and has triggered lawsuits, regulatory concerns and questions about digital security in the Bitcoin space.
In March 2025, Suman got a text message about suspicious activity on his Coinbase account. After Suman reported he was unaware of any unauthorized activity regarding his account, he got a call from a man who introduced himself as Brett Miller from Coinbase Security.
The guy sounded legit — he knew Suman’s setup, including that he used a Trezor Model One hardware wallet, a device meant to keep bitcoin and other digital assets offline and safe.
Suman told Bloomberg the guy knew everything, including the exact amount of digital assets he had.
The attacker persuaded Suman that his Trezor One hardware wallet and its funds were at risk and walked him through a “security procedure” that involved entering his seed phrase into a website that looked exactly like Coinbase, in order to “link his wallet to Coinbase”.
Nine days later, another guy called and repeated the process, saying the first one didn’t work.
And then, all of Suman’s digital assets — 17.5 bitcoin and 225 ether — were gone. At the time, bitcoin was around $103,000 and ether around $2,500, so the stolen stash was worth over $2 million.
Suman turned to digital assets after retiring from a decades-long art career. He stored his assets in cold storage to avoid the risks of online exchanges. He thought he did everything right.
Suman’s attackers didn’t pick his name out of a hat.
It looks like his personal info may have been leaked in the major breach at Coinbase. The company confirmed on May 15 that some of its customer service reps in India were bribed to access internal systems and steal customer data.
The stolen data included names, phone numbers, email addresses, balances and partial Social Security numbers.
According to Coinbase’s filing with the U.S. Securities and Exchange Commission, the breach may have started as early as January and affected nearly 1% of the company’s active monthly users — tens of thousands of people.
Hackers demanded $20M from Coinbase to keep the breach quiet but the company refused to pay. Coinbase says it fired the compromised agents and is setting aside $180M to $400M to reimburse affected users.
But so far, Suman hasn’t been told if he’ll be reimbursed.
Since the breach was disclosed, Coinbase has been hit with at least six lawsuits.
The lawsuits claim the company failed to protect user data and handled the aftermath poorly. One lawsuit filed in New York federal court on May 16 says Coinbase’s response was “inadequate, fragmented, and delayed.”
“Users were not promptly or fully informed of the compromise,” the complaint states, “and Coinbase did not immediately take meaningful steps to mitigate further harm.”
Some lawsuits are seeking damages, others are asking Coinbase to purge user data and improve its security. Coinbase has not commented on the lawsuits but pointed reporters to a blog post about its response.
Suman’s case is a cautionary tale across the Bitcoin world. He used a hardware wallet (considered the gold standard of Bitcoin security) and was still tricked through social engineering. Even the strongest security is useless if you don’t understand how Bitcoin works.
It’s never too early for Bitcoiners to start learning more about Bitcoin, especially on how to keep their stash safe. And the first lesson is “never ever share your seed phrase with anyone”.

2025-05-28 22:27:45👤 Generation X and Bitcoin: Between Invisibility, Structural Disillusionment, and Defiance
Generation X, born between 1965 and 1980, has been largely sidelined in generational discourse. Unlike the baby boomers —symbols of stability and prosperity— or millennials and Gen Z —constant fixtures in the media and cultural spotlight— Gen X remains the least mentioned, the least studied, and often not even recognized by its own members as a distinct generation.
Today, they are in midlife —a period that, according to the U-shaped curve of happiness, is one of the most emotionally and psychologically difficult stages: deteriorating health, professional stagnation, and the dual burden of caring for both parents and children. But their condition is not just a matter of age —it’s the product of a unique convergence of economic and political failure.
Structurally, Generation X reached its crucial phase of financial consolidation during the global economic crisis of 2008 —a moment that froze wage growth and severely limited access to housing, investment opportunities, and savings. In parallel, they faced increasing labor precarization: unstable contracts, outsourcing, erosion of social protections, and the dismantling of job security. Compared to other generations, their economic mobility was minimal. Even in terms of wealth accumulation and home ownership, many Gen Xers show weaker indicators than early-born millennials at the same life stage.
At the same time, many countries —especially in Latin America and parts of Europe— turned toward alternative models to free-market systems: socialist proposals that promised redistribution, justice, and equality. But in practice, these models led to state dependency, excessive intervention, economic rigidity, and a loss of productive dynamism. The outcome was devastating: rising poverty, institutional decay, inflation, plummeting investment, growing corruption, and a widespread collapse of trust.
For a generation raised on values of effort, autonomy, and social mobility, this ideological shift brought a double betrayal —first from liberalism, which failed to deliver on its promises, and then from socialism, which entrenched poverty, dependency, and dysfunction.
And yet, while younger generations increasingly embrace state-centric proposals like universal basic income, subsidies, or nationalizations as progressive solutions, many in Gen X see these not as innovation, but as déjà vu —a recycling of failed models they’ve already lived and paid for.
It’s at this point that Bitcoin emerges as more than just a financial technology. For many Gen Xers, Bitcoin is both a symbolic and concrete response — a refuge from a system that betrayed them. It’s not just about investment. It’s about individual sovereignty. They call it “fuck you money” because it represents a total break from traditional structures: it doesn’t depend on banks, governments, political parties, or promises that never materialize.
Bitcoin is money without permission, without censorship, without planned devaluation. It’s a tool for radical autonomy. For a generation marked by skepticism, self-reliance, and disillusionment, it stands as a quiet but powerful form of resistance — a way of saying: “I don’t depend on you. I don’t believe you. I don’t need you.”
Today, while others debate new statist models or more market reforms, many Gen Xers are simply opting out. Bitcoin isn’t just an economic choice — it’s a stance. A way to reclaim the individual control the system once denied them.

2025-05-29 07:29:43Autor: Anna Nagel. (Bild: Lukas Karl). Dieser Beitrag wurde mit dem Pareto-Client geschrieben. Sie finden alle Texte der Friedenstaube und weitere Texte zum Thema Frieden hier. Die neuesten Pareto-Artikel finden Sie auch in unserem Telegram-Kanal.
Die neuesten Artikel der Friedenstaube gibt es jetzt auch im eigenen Friedenstaube-Telegram-Kanal.
Wem in seinem Leben Schmerz zugefügt wurde, wer sich ungerecht behandelt fühlt oder wachen Auges in der Welt umschaut, kommt wahrscheinlich irgendwann mit der Frage in Berührung, wie das alles noch einmal «gut» werden kann. Wie kann die Welt sich mit sich selbst versöhnen? Und wie kann ich es selbst schaffen, mich mit ihr und den Menschen, die schlimme Taten vollbringen, wieder in harmonischer Akzeptanz zu verbinden? Kann und will ich gewisse Gräueltaten verzeihen oder gibt es das «Unverzeihliche»? Und selbst wenn ich wollte, wie könnte mir das gelingen?
Perspektivwechsel
Wenn wir an dem Zorn über begangenes Unrecht festhalten, schauen wir in der Regel aus immer derselben Perspektive auf das Geschehen. Mal um Mal erzürnen und empören wir uns darüber, erzählen uns und anderen stets die gleiche Geschichte, die uns allerdings – ebenfalls ein ums andere Mal – wieder selbst verletzt. Das Destruktive holt uns so ständig wieder ein; wir sehen und fühlen das unschuldige Kind und empfinden Verachtung für die Täter.
Die Perspektive zu wechseln lädt uns dazu ein, das Geschehen aus anderen Blickwinkeln zu betrachten und unser Bewusstsein von der schmerzlichen Wiederholung zu lösen. Wir können einmal weit rauszoomen und einen spirituellen Blickwinkel einnehmen, beispielsweise aus Sicht des All-ein-Bewusstseins, das sich in unzählige Seelen teilt, von denen wiederum Milliarden derzeit auf der Erde inkarniert sind. Dieses eine Bewusstsein möchte jede auch nur mögliche Erfahrung machen und durch die Trennung – die Erschaffung der Dualität – kann es sich selbst aus diesen Milliarden Persönlichkeiten heraus erfahren, um zu lernen. Während dieser scheinbaren Trennung vergessen wir, dass wir alle eins sind, dass wir alle aus demselben «Stoff» gemacht sind und nach diesem Spiel hier auf Erden unsere Erinnerung zurückerlangen und unsere Erfahrungen zurück geben in die eine «Quelle».
Unser aller Reise geht letztlich darum, hier auf der Erde aus diesem Zustand des Vergessens zu erwachen. Um dies zu erreichen und all diese Erfahrungen machen zu können und uns auch unter widrigsten Umständen an unsere wahre Essenz, an die Liebe, erinnern können, braucht es auch Akteure, die die Dunkelheit verkörpern – denn nur so haben wir die Wahl, ob wir uns von ihr einnehmen lassen oder uns für die Liebe und das Mitgefühl entscheiden. Der Täter sowie das Opfer sind dabei stets Aspekte unserer selbst – im Innen wie im Außen – und jeder einzelne verändert die Welt, indem er Liebe und Mitgefühl oder Hass und Verachtung wählt.
Eine etwas rationalere Herangehensweise wäre, zu schauen, was dazu führt, dass ein Mensch sich derart unmenschlich verhalten kann; also der Zugang über die Psychologie. Hier werden wir uns bewusst, dass jeder Täter auch einmal ein Kind war. Symbolisch sogar das Kind, mit dem wir jetzt im Beispiel mitfühlen und das wir gleichzeitig heute als erwachsenen Täter verachten. Natürlich kann man hier einwenden, dass nicht jedes Opfer zum Täter wird, aber man kann ebenso anerkennen, dass uns bei dieser Haltung das größte Stück fehlt; und zwar die Geschichte desjenigen, die Jahre dazwischen, sowie jeder einzelne Reiz und jedes Detail der Umstände.
Wie viel Schmerz und Leid muss ein Mensch erfahren, bis er unmenschlich wird? Mit Einbezug aller Umstände und Faktoren, der psychischen Schutzmechanismen traumatischer Erfahrungen sowie fehlender Ausbildung sozialer und empathischer Fähigkeiten auch im neuronalen Bereich kann man auch auf diesem Wege Verständnis erlangen. Sichtbar wird hierdurch auch, dass emotionaler Schmerz über Generationen weitergegeben wird und es schwer ersichtlich ist, wo denn die eigentliche Ursache liegt. Auch hier wird erkennbar, dass nur jeder bei sich anfangen kann und Verantwortung für seine Heilung – und damit gleichzeitig die anderer – übernehmen müsste, anstatt auf die Suche nach dem oder der «Schuldigen» zu gehen.
Was bedarf eigentlich der Vergebung?
Wenn es uns schwerfällt zu vergeben, also Groll und Verachtung loszulassen und Mitgefühl zu empfinden, ist es ebenfalls hilfreich, einmal hinzuschauen, worum es genau geht. Wenn es uns selbst betrifft, handelt es sich in der Regel um Schmerz, der uns willentlich, manchmal auch unbewusst, zugefügt wurde und den wir (noch) nicht loslassen können, weil er noch nicht verheilt ist. Darauf gehe ich später noch einmal ein. Oft geht es aber auch um uns unbekannte Menschen, von deren Verbrechen wir Kenntnis haben und deren Ungeheuerlichkeit uns aus der Fassung bringt. Es geht um Taten, die wir nicht nachvollziehen können, weder rational noch emotional. Wir meinen, selbst wenn jemand nicht spürte, was er anderen antut, so müsse er es doch wenigstens besser wissen. Das ist das, was uns Menschen ausmacht, mit anderen mitzufühlen und sie zu verstehen. Doch anscheinend gibt es Menschen, deren Persönlichkeit oder auch Psyche dazu absolut nicht in der Lage sind. Die keinen moralischen Kompass besitzen und keinerlei soziales Empfinden, denn sonst könnten sie bestimmte Taten nicht ausführen. Möglicherweise dissoziieren sie sich selbst so stark, dass diese für sie eine Normalität darstellen, sie diese entschuldigen beziehungsweise vor sich selbst rechtfertigen oder im extremen Fall keine Erinnerung mehr daran haben.
Uns erscheinen die fehlende Empathie sowie das fehlende Verständnis so fremd, dass wir es nicht nachvollziehen können. Uns fehlt die Nachvollziehbarkeit der Nichtnachvollziehbarkeit des Erlebens des anderen, und wir erachten diesen dadurch als unmenschlich. Denn menschlich wären doch eben diese Fähigkeiten wie Mitgefühl, Güte, Reflexion, Warmherzigkeit, Verständnis und Liebe. Zugleich erzeugen wir hier aber einen Konflikt, wenn wir sagen: «Da diese Menschen sich so unmenschlich verhalten, soll ihnen kein Mitgefühl und keine Vergebung entgegengebracht werden, sollen auch sie nicht menschlich behandelt werden», wodurch wir uns allerdings selbst unserer Menschlichkeit berauben.
«Aber der Täter hatte doch die freie Wahl, er hätte doch anders entscheiden können!» Ja, möglicherweise schon, aber jetzt haben wir die Wahl. Und wir haben viel leichtere Voraussetzungen dafür, menschlich zu handeln, weil wir gesunden Zugang zu unserer Empathie, Moral und unserer Ratio haben.
Hätte der Täter es geschafft, seinen Tätern zu verzeihen, würde er die Destruktivität, die er ab einem gewissen Zeitpunkt nicht mehr in sich tragen oder verdrängen konnte, nicht an anderen ausagieren. Es ist ihm nicht gelungen, vielleicht sogar weil etwas in ihm es für unmöglich hielt, Unmenschliches, das ihm zugefügt wurde, zu verzeihen. Aber uns kann es gelingen, diesen Kreislauf zu durchbrechen und uns nicht in ihn hineinziehen zu lassen; wir können dem «Dunklen» den Nährboden entziehen.
Manchmal nehmen wir an, würden wir das Unbeschreibliche verzeihen, bedeutete dies, dass wir es tolerieren oder gar gutheißen. Dem ist nicht so. Analog dazu habe ich manches Mal die Angst gehabt, würde ich aufhören, um meinen Freund zu trauern, bedeute dies, dass ich ihn nicht mehr vermisse. Auch das ist nicht richtig. Ich heile lediglich das, was mir Schmerzen zufügt, bis am Ende nur noch die Liebe bleibt. Und wenn wir verzeihen, ist es kein Gutheißen der Taten, es bedeutet ein Loslassen dessen, was uns damit verstrickt und das Destruktive nährt.
Mitgefühl beginnt bei uns selbst
«Daß ich dem Hungrigen zu essen gebe, dem vergebe, der mich beleidigt, und meinen Feind liebe- das sind große Tugenden. Was aber, wenn ich nun entdecken sollte, daß der armselige Bettler und der unverschämteste Beleidiger alle in mir selber sind und ich bedürftig bin, Empfänger meiner eigenen Wohltaten zu sein? Daß ich der Feind bin, den ich lieben muß - was dann?» – C. G. Jung
Mit diesem Zitat beginnt Dan Millman das Kapitel «Das Gesetz des Mitgefühls» in seinem Buch «Die universellen Lebensgesetze des friedvollen Kriegers». Die weise Frau lehrt dem Wanderer das Gesetz des Mitgefühls und erklärt, es sei «eine liebevolle Aufforderung, über unsere begrenzte Sichtweise hinauszuwachsen», auch wenn die Last dieser Aufgabe zuweilen sehr schwer wiegen könne. Genau deshalb müsse man daran denken, dass sie bei uns selbst beginnt und wir «geduldig» und «sanft» mit uns, unseren Gefühlen und Gedanken sein sollten.
Um dem – noch skeptischen – Wanderer zu veranschaulichen, wie wir Mitgefühl auch mit unseren Gegnern empfinden können, bat sie ihn, sich an eine Auseinandersetzung zu erinnern, in der er zornig, neidisch oder eifersüchtig war und sich diese Gefühle noch einmal zu vergegenwärtigen. Als er das tat, den Schmerz und die Wut wieder spürte, sagte sie zu ihm: «Und nun stell dir vor, daß der Mensch, mit dem du dich streitest, mitten in eurer erregten Auseinandersetzung plötzlich nach seinem Herzen faßt, einen Schrei ausstößt und zu deinen Füßen tot zu Boden sinkt.» Der Wanderer erschrak und auf Nachfrage der weisen Frau stellte er fest, dass er nun keinerlei Schmerz oder Wut mehr empfand. Sogleich aber kam ihm der Gedanke: «Aber – aber was wäre, wenn ich mich über den Tod dieses Menschen freuen würde? Wenn ich ihm nicht verzeihen könnte?», worauf die weise Frau antwortete: «Dann verzeih dir wenigstens selber deine Unversöhnlichkeit. Und in dieser Vergebung wirst du das Mitgefühl finden, das deinen Schmerz heilt, als Mensch in dieser Welt zu leben.»
Weiter erinnert uns die weise Frau daran, dass wir alle, während wir hier auf der Erde sind, Träume, Hoffnungen und Enttäuschungen haben; und dass diese, sowie letztlich der Tod, uns alle verbinden.
Es ist ein Prozess
Dan Millman sagt hier in Gestalt der Weisen Frau, dass Mitgefühl bei uns selbst beginnt und diesen Aspekt möchte ich noch einmal hervorheben. Es kann nämlich passieren, dass wir uns in einer oberflächlichen Vergebung wieder finden, weil wir meinen, es sei richtig und moralisch, anderen zu verzeihen, ohne aber die tieferen Schichten dabei zu fühlen. Das ist dann leider nichts anderes, als Verdrängung. Gerade wenn wir selbst Opfer von Ungerechtigkeit, physischer oder mentaler Gewalt wurden, ist es unerlässlich den Heilungsweg in Gänze zu durchschreiten, und in den Wachstumsprozess zu verwandeln, der uns Mitgefühl und Weisheit lehrt. Und dazu gehören die Wut auf das Begangene, die Verzweiflung, die Ungerechtigkeit und Ohnmacht zu fühlen, uns auf «unsere Seite» zu stellen und Partei für uns selbst zu ergreifen, bevor es ernstlich möglich wird, zu verzeihen. Zunächst fühlen wir mit uns selbst den Schmerz und befreien die Gefühle, die wir uns möglicherweise nie trauten zu fühlen, all die Wut und den Groll. Erst später kann dann aus dem Inneren heraus das weitere Erkennen stattfinden und Heilung und Vergebung geschehen.
Vergebung findet im Herzen statt
Die hier in diesem Text von mir aufgeführten Perspektiven sind nur zwei, drei kleine Beispiele für Sichtweisen, die man einnehmen könnte, um zu neuen Einsichten zu gelangen. Sie sollen niemanden von irgendetwas überzeugen, sondern als Anregung dienen. Denn letztlich geht es darum, Vergebung in sich selbst zu finden. Vergebung ist also etwas, das aus dem Inneren heraus entsteht; ein Ergebnis eines tiefen Verständnisses und Fühlens, ja eines Erkennens. Auf dieser Reise gehen wir unterschiedliche Blickwinkel und Versionen ab, bis wir im Herzen ankommen, es sich öffnet und wir plötzlich «klar» sehen. Daraufhin breitet sich Wärme im Körper aus, Liebe durchströmt uns, begleitet möglicherweise von einem Gefühl leiser Euphorie, möglicherweise auch einem leichten Schmerz und Tränen – sowohl ein paar der Traurigkeit als auch welchen der Dankbarkeit. Das Loslassen und die Befreiung sind spürbar und nur für jeden persönlich erfahrbar, der sich auf diesen Weg begibt und seine individuelle Ansicht findet, die ihn befreit und erlöst.
Meiner Meinung nach bedeutet also Vergebung eine Öffnung des Herzens, ein Erkennen und ein Hineinwachsen in die Perspektive der Liebe. Sie ist nicht auf rationaler Ebene zu finden; die rationale Ebene kann nur dabei helfen, den Weg zum Mitgefühl zu beschreiten, denn:
«Man sieht nur mit dem Herzen gut. Das Wesentliche ist für die Augen unsichtbar.»

Leaders Rally Behind BTC at Bitcoin 2025 Conference: Strategic Reserves, Market Clarity, and Legislative MomentumAt Bitcoin 2025, top U.S. lawmakers and Coinbase’s Chief Policy Officer discussed the U.S. government’s shifting tone on Bitcoin, strategic reserves, regulatory frameworks, and legislation—all pointing toward a bullish future for digital assets.
In a panel moderated by Grant McCarty, Co-President of the Bitcoin Policy Institute, the Bitcoin 2025 Conference saw a major spotlight on U.S. policy shifts surrounding digital assets. U.S. Representatives Byron Donalds and Bryan Steil were joined by Faryar Shirzad, Chief Policy Officer at Coinbase, to highlight what they described as a watershed moment for Bitcoin in Washington.

US Congressman Byron Donalds says he's voting for the Strategic Bitcoin Reserve Act
"Bitcoin has proven to be a holder of value" pic.twitter.com/NuQlZ26Lmy
— Bitcoin Magazine (@BitcoinMagazine) May 27, 2025
“What the president and his team are doing is choosing to step into the digital assets marketplace,” said Byron Donalds. “Bitcoin is a key asset because it has demonstrated to be a holder of value outside of fiat currency and central banking.” Donalds emphasized that President Trump is taking the long view—strategically recognizing Bitcoin’s role in a national reserve capacity.
Bryan Steil pointed to Trump’s media magnetism and political leverage as the driver behind recent legislative momentum: “What he’s done is put a spotlight on the exact three bills… giving us the ability to drive forward.” He noted that legislation is difficult to pass, but with executive support, there’s newfound energy and opportunity to cross the finish line.
Shirzad echoed that sentiment: “The tone from the top point is exactly what Donald Trump has showed us… He wants a market structure built. He wants a much more strategic approach.” Coinbase, Shirzad added, sees the impact firsthand—legislators now recognize the need to support innovation rather than stifle it.
Donalds added: “If you talk to any business owner in the world, the number one thing they desire more than anything else is certainty and consistency.” That, he said, is what will turn Bitcoin into a trillion-dollar industry in the U.S., instead of one bogged down by regulatory ambiguity and legal overhead.
On the regulatory front, Steil noted: “Under the Biden administration, policy was being developed through enforcement actions. Bitcoin is decentralized and should be treated as a commodity.” Shirzad agreed, pushing for “regulatory therapy” to unleash billions still sidelined.
McCarty closed with mention of the Blockchain Regulatory Clarity Act—legislation that would protect open-source developers from rogue regulatory action: “It allows developers to operate without being punished.”
Donalds summed it up: “There’s only going to be 21 million ever in creation. That can’t be eroded by central banks. A strategic reserve for Bitcoin is critical in my opinion for the United States.”

2025-05-28 21:02:30Panama City may be the next Latin American city to adopt bitcoin, after El Salvador.
Panama City Mayor Mayer Mizrachi has got the bitcoin world excited after hinting that the city might have a bitcoin reserve. The speculation started on May 16 when Mizrachi posted a simple but powerful message on X:
Two words. That’s it. What makes it special is that it came after a high-profile meeting with Max Keiser and Stacy Herbert, two key figures behind El Salvador’s bitcoin strategy.
Keiser is an advisor to El Salvador’s President Nayib Bukele and Herbert leads the country’s Bitcoin Office.
El Salvador became the first country to adopt bitcoin as legal tender back in 2021. Since then, it has been building a national bitcoin reserve, currently holding 6,179 BTC worth around $640 million. It’s also using geothermal energy to power bitcoin mining in an eco-friendly way.
El Salvador’s bitcoin treasury — Bitcoin.gob.sv
Mizrachi’s meeting with Keiser and Herbert was about how Panama could do the same. While the details of the conversation are private, Keiser shared on social media that the two countries will play a big role in the future of Bitcoin.
“Bitcoin is transforming Central America,” Keiser wrote. “El Salvador’s geothermal & Panama’s hydro-electric will power the Bitcoin revolution.”
Max Keiser on X
Panama with its hydroelectric power could be a hub for green bitcoin mining.
Mizrachi has not announced a bitcoin reserve plan nor submitted a proposal to the National Assembly. But his post and public appearances suggest it’s being considered.
He will be speaking at the upcoming Bitcoin 2025 Conference in Las Vegas just days after his social media post. Many expect he will share more about Panama City’s bitcoin plans during his talk.
If Mizrachi pushes for a bitcoin reserve, he will need to work with national lawmakers to pass new legislation. So far, there is no evidence of that.
Even without a bitcoin reserve, Panama City is already going big on digital assets.
In April 2025, the city council approved a measure to allow residents to pay taxes, fees, fines and permits with digital currencies. Supported tokens are bitcoin (BTC), ethereum (ETH), USD Coin (USDC) and Tether (USDT).
To comply with financial laws, the city has partnered with a bank that instantly converts these digital assets into U.S. dollars. According to Mizrachi, this way it’s easier for residents to use digital assets and the city’s financial operations will be transparent and legal.
Another part of the meeting with El Salvador’s advisors was education.
Stacy Herbert confirmed that Panama City will be integrating El Salvador’s financial literacy book, “What is Money?” into their digital library system. The goal is to help students, teachers and the general public understand bitcoin and digital currencies in modern finance.
This is a trend in Latin America where countries are looking for alternatives to traditional banking systems. Inflation, economic instability and the rise of decentralized finance are forcing governments to look into new financial tools.

FAQ
In the ever-evolving world of cryptocurrencies, Bitcoin stands as a beacon, often dictating the mood of the entire crypto market. Its price fluctuations are closely watched by investors, analysts, and enthusiasts alike. Max Keiser, a prominent figure in the crypto space, recently shed light on some intriguing factors that might be influencing Bitcoin's current price trajectory. This article delves into Keiser's insights, exploring the broader implications of global events on Bitcoin's market performance.
The Influence of Global Oil Prices
Max Keiser, a renowned Bitcoin advocate and former trader, recently drew attention to the interplay between global oil prices and Bitcoin's market performance. Responding to a post by German economics expert, Holger Zschaepitz, Keiser highlighted the significance of Brent oil reaching $90 per barrel for the first time since the previous November. According to Keiser, the surge in oil prices, driven by Saudi Arabia's decision to extend its reduction in oil production for another three months, has had ripple effects in the financial world. One of these effects is the shift of investor interest towards higher interest deposit USD accounts. This diversion of investments is creating what Keiser terms as "a small headwind for Bitcoin," implying that as traditional markets like oil show promise, some investors might be reconsidering their cryptocurrency positions.
Bitcoin's Roller Coaster Ride
The cryptocurrency market, known for its volatility, witnessed Bitcoin's price undergoing significant fluctuations recently. A notable event that gave Bitcoin a temporary boost was Grayscale's triumph over the SEC in a legal battle concerning the conversion of its Bitcoin Trust into a spot ETF. This victory led to a rapid 7.88% spike in Bitcoin's price within a mere hour, pushing it from the $26,000 bracket to briefly touch the $28,000 threshold. However, this euphoria was short-lived. Over the subsequent week, the cryptocurrency saw its gains erode, settling in the $25,400 range. At the time the reference article was penned, Bitcoin was hovering around $25,688.
Anticipation Surrounding the 2024 Halving Event
The Bitcoin community is abuzz with anticipation for the next scheduled Bitcoin halving, projected to take place in April-May 2024. This event will see the rewards for Bitcoin miners being slashed by half, resulting in a decreased supply of Bitcoin entering the market. Historically, such halvings have acted as catalysts, propelling Bitcoin's price upwards. A case in point is the aftermath of the 2020 halving, post which Bitcoin soared to an all-time high of $69,000 in October 2021. However, some financial analysts argue that this surge was less about the halving and more a consequence of the extensive monetary measures adopted by institutions like the US Federal Reserve. These measures, taken in response to the pandemic and the ensuing lockdowns, flooded the market with cash, potentially driving up Bitcoin's price.
The Broader Crypto Landscape
While Bitcoin remains the most dominant and influential cryptocurrency, it's essential to consider its position within the broader crypto ecosystem. Other cryptocurrencies, often referred to as 'altcoins', also play a role in shaping investor sentiment and market dynamics. Factors such as technological advancements, regulatory changes, and global economic shifts not only impact Bitcoin but the entire crypto market. As investors diversify their portfolios and explore newer blockchain projects, Bitcoin's role as the market leader is continually tested. Yet, its pioneering status and proven resilience make it a focal point of discussions and analyses in the crypto world.
Conclusion
Bitcoin, the flagship cryptocurrency, has always been subject to a myriad of market forces and global events. While its inherent potential remains undeniable, the current market landscape, shaped by factors ranging from oil prices to global economic policies, presents challenges. Yet, with events like the 2024 halving on the horizon, there's an air of optimism among Bitcoin enthusiasts and investors about the future trajectory of this digital asset.

2024-12-23 16:47:01At the intersection of philosophy, theology, physics, biology, and finance lies a terrifying truth: the fiat monetary system, in its current form, is not just an economic framework but a silent, relentless force actively working against humanity's survival. It isn't simply a failed financial model—it is a systemic engine of destruction, both externally and within the very core of our biological existence.
The Philosophical Void of Fiat
Philosophy has long questioned the nature of value and the meaning of human existence. From Socrates to Kant, thinkers have pondered the pursuit of truth, beauty, and virtue. But in the modern age, the fiat system has hijacked this discourse. The notion of "value" in a fiat world is no longer rooted in human potential or natural resources—it is abstracted, manipulated, and controlled by central authorities with the sole purpose of perpetuating their own power. The currency is not a reflection of society’s labor or resources; it is a representation of faith in an authority that, more often than not, breaks that faith with reckless monetary policies and hidden inflation.
The fiat system has created a kind of ontological nihilism, where the idea of true value, rooted in work, creativity, and family, is replaced with speculative gambling and short-term gains. This betrayal of human purpose at the systemic level feeds into a philosophical despair: the relentless devaluation of effort, the erosion of trust, and the abandonment of shared human values. In this nihilistic economy, purpose and meaning become increasingly difficult to find, leaving millions to question the very foundation of their existence.
Theological Implications: Fiat and the Collapse of the Sacred
Religious traditions have long linked moral integrity with the stewardship of resources and the preservation of life. Fiat currency, however, corrupts these foundational beliefs. In the theological narrative of creation, humans are given dominion over the Earth, tasked with nurturing and protecting it for future generations. But the fiat system promotes the exact opposite: it commodifies everything—land, labor, and life—treating them as mere transactions on a ledger.
This disrespect for creation is an affront to the divine. In many theologies, creation is meant to be sustained, a delicate balance that mirrors the harmony of the divine order. Fiat systems—by continuously printing money and driving inflation—treat nature and humanity as expendable resources to be exploited for short-term gains, leading to environmental degradation and societal collapse. The creation narrative, in which humans are called to be stewards, is inverted. The fiat system, through its unholy alliance with unrestrained growth and unsustainable debt, is destroying the very creation it should protect.
Furthermore, the fiat system drives idolatry of power and wealth. The central banks and corporations that control the money supply have become modern-day gods, their decrees shaping the lives of billions, while the masses are enslaved by debt and inflation. This form of worship isn't overt, but it is profound. It leads to a world where people place their faith not in God or their families, but in the abstract promises of institutions that serve their own interests.
Physics and the Infinite Growth Paradox
Physics teaches us that the universe is finite—resources, energy, and space are all limited. Yet, the fiat system operates under the delusion of infinite growth. Central banks print money without concern for natural limits, encouraging an economy that assumes unending expansion. This is not only an economic fallacy; it is a physical impossibility.
In thermodynamics, the Second Law states that entropy (disorder) increases over time in any closed system. The fiat system operates as if the Earth were an infinite resource pool, perpetually able to expand without consequence. The real world, however, does not bend to these abstract concepts of infinite growth. Resources are finite, ecosystems are fragile, and human capacity is limited. Fiat currency, by promoting unsustainable consumption and growth, accelerates the depletion of resources and the degradation of natural systems that support life itself.
Even the financial “growth” driven by fiat policies leads to unsustainable bubbles—inflated stock markets, real estate, and speculative assets that burst and leave ruin in their wake. These crashes aren’t just economic—they have profound biological consequences. The cycles of boom and bust undermine communities, erode social stability, and increase anxiety and depression, all of which affect human health at a biological level.
Biology: The Fiat System and the Destruction of Human Health
Biologically, the fiat system is a cancerous growth on human society. The constant chase for growth and the devaluation of work leads to chronic stress, which is one of the leading causes of disease in modern society. The strain of living in a system that values speculation over well-being results in a biological feedback loop: rising anxiety, poor mental health, physical diseases like cardiovascular disorders, and a shortening of lifespans.
Moreover, the focus on profit and short-term returns creates a biological disconnect between humans and the planet. The fiat system fuels industries that destroy ecosystems, increase pollution, and deplete resources at unsustainable rates. These actions are not just environmentally harmful; they directly harm human biology. The degradation of the environment—whether through toxic chemicals, pollution, or resource extraction—has profound biological effects on human health, causing respiratory diseases, cancers, and neurological disorders.
The biological cost of the fiat system is not a distant theory; it is being paid every day by millions in the form of increased health risks, diseases linked to stress, and the growing burden of mental health disorders. The constant uncertainty of an inflation-driven economy exacerbates these conditions, creating a society of individuals whose bodies and minds are under constant strain. We are witnessing a systemic biological unraveling, one in which the very act of living is increasingly fraught with pain, instability, and the looming threat of collapse.
Finance as the Final Illusion
At the core of the fiat system is a fundamental illusion—that financial growth can occur without any real connection to tangible value. The abstraction of currency, the manipulation of interest rates, and the constant creation of new money hide the underlying truth: the system is built on nothing but faith. When that faith falters, the entire system collapses.
This illusion has become so deeply embedded that it now defines the human experience. Work no longer connects to production or creation—it is reduced to a transaction on a spreadsheet, a means to acquire more fiat currency in a world where value is ephemeral and increasingly disconnected from human reality.
As we pursue ever-expanding wealth, the fundamental truths of biology—interdependence, sustainability, and balance—are ignored. The fiat system’s abstract financial models serve to disconnect us from the basic realities of life: that we are part of an interconnected world where every action has a reaction, where resources are finite, and where human health, both mental and physical, depends on the stability of our environment and our social systems.
The Ultimate Extermination
In the end, the fiat system is not just an economic issue; it is a biological, philosophical, theological, and existential threat to the very survival of humanity. It is a force that devalues human effort, encourages environmental destruction, fosters inequality, and creates pain at the core of the human biological condition. It is an economic framework that leads not to prosperity, but to extermination—not just of species, but of the very essence of human well-being.
To continue on this path is to accept the slow death of our species, one based not on natural forces, but on our own choice to worship the abstract over the real, the speculative over the tangible. The fiat system isn't just a threat; it is the ultimate self-inflicted wound, a cultural and financial cancer that, if left unchecked, will destroy humanity’s chance for survival and peace.

US Senator Cynthia Lummis Discusses Bitcoin Reserve, Stablecoin Legislation, and Market Structure Bill at Bitcoin 2025 ConferenceAt the 2025 Bitcoin Conference in Las Vegas, U.S Senator Cynthia Lummis and CLO of Coinbase Paul Grewal discussed the market structure bill, stablecoin bill, future taxing system, bitcoin strategy reserve and bitcoin mining.
Cynthia Lummis started by commenting about the market structure bill and stablecoin bill.
“The market structure bills is probably more important to a lot of the people in this conference than the stablecoin bill because there are a lot of businesses, yours among them,” said Lummis. “There are businesses for people who either buy and hold, so they want a custodial service or there are companies that lend Bitcoin, there is a futures market for Bitcoin, there are so many ways in which Bitcoin can interface with fiat currency with the US dollar.”
Lummis also mentioned the tax system that she wants to implement and what her office has submitted to the finance committee.
“As the lighting network develops and companies like Strike sort of have been leaders in that space,” added Lummis. “Create an opportunity for transactions to occur on a daily basis in Bitcoin. Everything from buying a cup of coffee to dinner somewhere. It would be helpful that certain transactions of that size below 600 dollars per transaction, not be subject to taxation.”
During her speech, she went into detail on one the biggest problems lawmakers are facing against digital assets.
“Part of the problem in the last four years has been largely regulatory agencies that have been very hostile towards digital assets, so we are trying to change as fast as we can,” said Lummis. “It doesn’t happen overnight. We don’t even have a confirmed IRS director in place yet, so it is really hard to get these structural changes enacted by the rule makers at the IRS when there is no IRS commission yet in place.”
Ending the panel, Lummis addressed one of the biggest reasons the US government should get into Bitcoin.
“We are 37 trillion dollars in debt, so if we bought and held a million Bitcoin for 20 years it will cut that debt in half and we have underperforming assets that can be converted to Bitcoin without borrowing additional money. Bitcoin is such an important Global Strategic asset and it is not only important in the economy, but in our global defense because there are components to our defense. One is having a lethal war fighting machine that can overcome other armies, another military effort. Another one is having an economic machine that can overcome other currencies.” She continued, “Even our military generals say that bitcoin is an important deterrent to aggression from other countries, especially from China.”

2025-05-29 01:40:28เรามาดู แลคเชอร์ประวัติศาสตร์ ที่พลิกโลกแห่งการเกษตรและอาหารของมนุษย์ชาติกันครับ เรามาดูความแยบยลที่สามารถจูงใจคนมากมายให้เห็นถึงข้อดีของเนื้อจากแลบ เขาทำได้ยังไง เรามาศึกษาการสื่อสารกันครับ
เรื่องมันเริ่มจากการประชุม World Economic Forum ปี 2015 ที่ศาสตราจารย์ Mark Post นักเภสัชวิทยาชาวดัตช์ ที่เรารู้จักกันไปแล้ว ซึ่งตอนนั้นเป็นศาสตราจารย์ด้านสรีรวิทยาของหลอดเลือดอยู่ที่ Maastricht University และเป็นผู้ร่วมก่อตั้งบริษัท Mosa Meat ได้ลุกขึ้นมาเล่าเรื่อง "เนื้อเพาะเลี้ยง" หรือ cultured meat ให้คนทั้งห้องฟัง
สิ่งที่เขาพูดมันไม่ใช่แค่นวัตกรรมใหม่ แต่คือคำเตือนที่จริงจัง ว่าถ้ามนุษย์ยังผลิตเนื้อสัตว์แบบเดิม เรากำลังวิ่งเข้าใกล้ปัญหาใหญ่ที่รออยู่ข้างหน้า
ศาสตราจารย์ Post เล่าไว้ได้น่าสนใจมาก เขาบอกว่าแค่จะได้แฮมเบอร์เกอร์ 1 ชิ้นขนาดหนึ่งในสี่ปอนด์ เราต้องใช้เมล็ดธัญพืช 7 ปอนด์ ใช้น้ำจืด 50 แกลลอน และพื้นที่ดินอีก 70 ตารางฟุต นั่นแปลว่าเรากำลังเปลี่ยนของดีในธรรมชาติ ข้าว น้ำ ดิน ไปเป็นของที่กินหมดใน 10 นาที แล้วหิวใหม่ได้ในอีกครึ่งชั่วโมง
เหตุผลก็เพราะวัวมันไม่ได้แปลงโปรตีนพืชมาเป็นเนื้อได้มีประสิทธิภาพนัก พูดอีกแบบคือ มันเปลืองเกินไป
ตอนนี้พื้นที่เพาะปลูกของโลกกว่า 70% ถูกใช้ไปในการผลิตเนื้อสัตว์ คิดดูสิว่าถ้าเราหาทางที่ดีกว่านี้ได้ เราจะมีพื้นที่ว่างกลับคืนมาแค่ไหน
แถมวัวไม่ใช่แค่กินเก่งนะ ยังปล่อยก๊าซเก่งด้วย โดยเฉพาะมีเทนที่ทำให้โลกร้อนพอๆ กับอุตสาหกรรมการขนส่งเลยทีเดียว ศาสตราจารย์ Post เล่าว่า ทุกครั้งที่เขาเห็นวัวยืนเคี้ยวหญ้า เขาไม่ได้เห็นแค่วัว...แต่เห็นเมฆก๊าซมีเทนลอยมาด้วย
และที่น่าคิดคือ เมื่อรายได้ของคนในอินเดียหรือจีนสูงขึ้น พวกเขาจะกินเนื้อเพิ่มตามรายได้ ซึ่งสถิติบอกว่าภายในปี 2050 ความต้องการเนื้อสัตว์จะเพิ่มขึ้นเป็น สองเท่า จากปัจจุบัน
แต่ศาสตราจารย์ก็ไม่ได้มองว่าเนื้อเป็นปีศาจ เขาบอกว่า มนุษย์ถูกสร้างมาให้รักเนื้อ เนื้อคือสิ่งที่มาพร้อมวิวัฒนาการ เราได้พลังงานจากมัน สมองเราใหญ่ขึ้นเพราะมัน และกลายเป็นมนุษย์เพราะมัน
แม้จะมีคนอีกกว่าสองพันล้านที่เป็นมังสวิรัติ ส่วนใหญ่อาจเพราะไม่มีทางเลือก แต่อย่างน้อยพวกเขาก็อยู่รอดได้ แต่ก็ปฏิเสธไม่ได้ว่า คนที่เคยล่า เคยกินเนื้อ จะรู้สึกตื่นเต้นทุกครั้งที่ได้แบ่งเนื้อกันบนโต๊ะ
ศาสตราจารย์ Post เองก็ยังชอบกินเนื้อ แต่เขาอยากได้เนื้อที่ได้มาจากทางเลือกที่ดีกว่า ไม่ใช่ทางที่พาโลกเข้า ICU
เนื้อเพาะเลี้ยงเริ่มจากหลักการง่ายๆ ที่เรารู้มาตั้งแต่ช่วงปี 2000 ว่า ในกล้ามเนื้อของสัตว์มี สเต็มเซลล์ รอคอยจะซ่อมแซมเนื้อเยื่อหากมันได้รับบาดเจ็บ
แค่เอาชิ้นกล้ามเนื้อเล็กๆ จากวัว ขนาดแค่ 1 ซม. x 1 มม. มาแยกสเต็มเซลล์ออกมาเลี้ยงให้ขยายตัว
เฮียว่าอันนี้น่าทึ่งมาก เพราะจากตัวอย่างเล็กๆ ชิ้นเดียว สามารถผลิตเนื้อวัวได้ถึง 10,000 กิโลกรัม เลยนะ!
แปลว่าเราสามารถลดจำนวนวัวทั้งโลกจากครึ่งพันล้านตัว เหลือแค่ประมาณ 30,000 ตัวได้เลย
และถ้าให้เซลล์กล้ามเนื้อพวกนี้อยู่ในสภาพแวดล้อมที่เหมาะสม มันก็จะเริ่มสร้างกล้ามเนื้อขึ้นมาเอง โดยเฉพาะถ้าเรากระตุ้นให้มันรู้สึกเหมือนกำลัง “ออกกำลัง” อยู่ เช่น ใส่แรงตึงเข้าไป
ทีมนักวิจัยของเขาเลี้ยงเซลล์เหล่านี้ให้เติบโตในรูปวงแหวนคล้ายโดนัท ครบ 3 สัปดาห์ กล้ามเนื้อจะเริ่มหดตัว สร้างความตึง และกลายเป็นเนื้อกล้ามเนื้อแบบเต็มตัวที่ดูไม่ต่างจากกล้ามเนื้อในสเต็กจริงๆ เลย
ปี 2013 ทีมของ Mark Post ผลิตเส้นใยกล้ามเนื้อจำนวน 10,000 เส้น เอามาทำแฮมเบอร์เกอร์ และนำไปเปิดตัวในงานแถลงข่าวที่ลอนดอน เป็นเหมือนการโชว์ทำอาหารผสมกับเปิดงานวิจัย
จุดประสงค์คือจะพิสูจน์ให้โลกเห็นว่า “เฮ้ย! สิ่งนี้ไม่ใช่แค่ไอเดียลอยๆ แต่มันทำได้จริง และจำเป็นต้องทำจริงๆ เพราะเรากำลังจะเจอวิกฤต”
ราคาแฮมเบอร์เกอร์ตอนนั้นคือ 250,000 ยูโร
มีเชฟผู้กล้าปรุง และอาสาสมัครสองคนลองชิม พวกเขาบอกว่า “ก็โอเคในฐานะเบอร์เกอร์ราคาเท่านี้ แต่ก็อยากได้รสเข้มกว่านี้หน่อย” เพราะยังไม่มีไขมัน เลยรสจืดไปหน่อย
แต่ที่สำคัญคือ พวกเขายืนยันว่า “มันคือเนื้อจริงๆ” ทั้งเนื้อสัมผัสและโครงสร้าง
แค่มีต้นแบบยังไม่พอ เพราะจะทำให้ขายได้จริง ต้องผ่านด่านสำคัญ เนื้อต้องผลิตได้โดยใช้ทรัพยากรน้อยกว่าการเลี้ยงวัวจริง การประเมินเบื้องต้นจาก University of Oxford พบว่า เนื้อเพาะเลี้ยงใช้พื้นที่น้อยลง 90% น้ำลดลง 90% พลังงานลดลง 60–70%
ทุกอย่างที่ใช้ในการเลี้ยงเซลล์ต้องมีจำนวนมากพอหรือหมุนเวียนใช้ได้ ที่น่าหนักใจคือ การเลี้ยงเซลล์ต้องใช้ “ซีรั่มจากลูกวัว” ซึ่งได้มาจากเลือดวัว ถ้าลดจำนวนวัว เราก็ไม่มีซีรั่ม แต่ตอนนี้มีงานพัฒนาไปเยอะแล้ว กำลังหาวิธีทำเซลล์กล้ามเนื้อโดยไม่ต้องพึ่งซีรั่มจากสัตว์
ไม่ใช่แค่โปรตีน แต่ต้องเป็น "เนื้อ" ในทุกความรู้สึก นักวิจัยพยายามปรับสภาพแวดล้อมการเพาะเลี้ยง เช่น ความเข้มข้นของออกซิเจน เพื่อให้เซลล์แสดงโปรตีนสำคัญ เช่น myoglobin ที่ทำให้เนื้อมีสีและรสชาติเหมือนเนื้อจริง
การยอมรับของผู้บริโภคเป็นอีกด่านสำคัญที่เนื้อเพาะเลี้ยงต้องข้ามผ่านให้ได้ ไม่ใช่แค่เรื่องรสชาติหรือคุณค่าทางโภชนาการเท่านั้น แต่ยังเป็นเรื่องของ "ใจ" ที่ต้องเปิดรับสิ่งใหม่ที่ไม่คุ้นเคย ศาสตราจารย์ Post เล่าว่า ในการสำรวจผู้บริโภคในอังกฤษและเนเธอร์แลนด์ พบว่ามีคนไม่น้อยที่ยินดีจะลองกินเนื้อเพาะเลี้ยง ถึง 52% ของชาวดัตช์ และ 60% ของชาวอังกฤษเลยทีเดียว
เขาเปรียบเทียบว่า จริงๆ แล้ว คนเรายอมกินฮอทดอกโดยไม่รู้ด้วยซ้ำว่าทำมาจากอะไร หรือผ่านอะไรมาบ้าง ขอแค่มัน "อร่อย ถูก และดูปลอดภัย" ก็เพียงพอแล้วสำหรับคนส่วนใหญ่ ดังนั้นเนื้อเพาะเลี้ยงจึงไม่ต่างกันมากนัก ขอเพียงให้คนรู้สึกว่า “กินแล้วไม่ตาย” และ “ไม่ได้แปลกจนใจฝ่อ” เท่านั้นแหละ วันหนึ่งมันก็จะกลายเป็นของธรรมดาในตู้เย็นเหมือนกับโยเกิร์ตหรือไส้กรอกนั่นเอง
ในด้านของราคา แม้จะยังไม่ถูกเท่าไส้กรอกในซูเปอร์ แต่ก็ลดลงมาไกลจากจุดเริ่มต้นแบบสุดๆ จากชิ้นต้นแบบราคา 250,000 ดอลลาร์ในปี 2013 ตอนนี้ต้นทุนลดลงมาเหลือประมาณ 65 ดอลลาร์ต่อกิโลกรัม (ยังไม่รวมเทคโนโลยีล้ำหน้าอื่นๆ ที่กำลังพัฒนาอยู่) ซึ่งก็ถือว่าอยู่ในระดับเดียวกับเนื้อวากิวหรือสเต๊กเกรดพรีเมียมเลยทีเดียว เป้าหมายคือทำให้ถูกลงอีก และผลิตได้ในระดับอุตสาหกรรมให้เพียงพอกับคนทั้งโลก ไม่ใช่ของฟุ่มเฟือยสำหรับคนรวยเท่านั้น
แต่วิสัยทัศน์ที่น่าสนใจจริงๆ คือ ภาพของอนาคตที่ศาสตราจารย์ Post วาดไว้ เขาเชื่อว่าเทคโนโลยีนี้เรียบง่ายพอที่จะขยายไปสู่ครัวเรือนหรือชุมชนเล็กๆ ได้ วันหนึ่งเราอาจได้เห็นการเพาะเลี้ยงเซลล์จากหมูที่เลี้ยงอยู่ข้างบ้าน แล้วเอาไปปั่นเป็นหมูสับแบบสดใหม่ ไม่ต้องฆ่าสัตว์ ไม่ต้องส่งโรงงาน ไม่ต้องตัดต่อพันธุกรรม แค่นั่งรอเหมือนหมักแป้งเปรี้ยว แล้วได้เนื้อสดๆ มาใส่ต้มจืด
และนั่นแหละคือ "การเปลี่ยนกรอบคิดเรื่องเนื้อสัตว์" แบบพลิกฝ่ามือ
มันจะไม่ใช่เรื่องการฆ่าอีกต่อไป ไม่ใช่เรื่องของฟาร์มกลิ่นฉี่ หรือสายพานโรงฆ่าสัตว์ มันจะเป็น "ผลิตภัณฑ์ใหม่" ที่เราสร้างได้ ควบคุมได้ และปรับแต่งได้ เช่น เพิ่มโอเมก้า 3 ในเซลล์ไขมันให้สูงขึ้น หรือทำให้เนื้อไม่มีคอเลสเตอรอลเลยก็ยังได้
แม้ศาสตราจารย์ Post จะเน้นเรื่องความมั่นคงทางอาหารและผลกระทบต่อสิ่งแวดล้อมเป็นหลัก แต่เขาก็ยอมรับว่า สำหรับคนกินทั่วๆ ไป ประเด็นที่ "ไม่มีสัตว์ต้องเจ็บปวด" จะกลายเป็นจุดขายที่สำคัญในใจของผู้บริโภค
เขาเชื่อว่า เมื่อวันนั้นมาถึง วันที่เรายืนอยู่หน้าตู้แช่ในซูเปอร์ แล้วเห็นผลิตภัณฑ์สองชิ้นวางข้างกัน — หนึ่งคือเนื้อวัวที่มาจากฟาร์ม และอีกหนึ่งคือเนื้อเพาะเลี้ยงที่ไม่เคยมีวัวต้องร้องไห้แม้แต่นิดเดียว — การตัดสินใจอาจจะไม่ง่าย แต่ "จะมีคนจำนวนมากขึ้นเรื่อยๆ ที่เลือกแบบไม่ต้องฆ่า"
เพราะสุดท้าย เราไม่ได้แค่กินเนื้อ… เรากำลังกิน “ความเชื่อ” ลงไปด้วย #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-05-28 20:37:58Bitcoin: Peer-to-peer sistem elektronskog novca
Satoshi Nakamoto
satoshin@gmx.com
Prevedeno na srpski sa bitcoin.org/bitcoin.pdf od strane ECD
Sažetak. Potpuna peer-to-peer verzija elektronskog novca omogućila bi slanje uplata putem interneta direktno od jedne strane ka drugoj bez posredovanja finansijskih institucija. Digitalni potpisi pružaju deo rešenja, ali se glavni benefiti gube ako je i dalje potrebna pouzdana treća strana za sprečavanje dvostruke potrošnje. Predlažemo rešenje problema dvostruke potrošnje korišćenjem peer-to-peer mreže. Mreža vremenski označava transakcije tako što ih hešuje u tekući lanac dokaza o radu (proof of work) temeljen na hešu, formirajući zapis koji se ne može promeniti bez ponovnog rada i objavljivanja dokaza o tom radu. Najduži lanac ne služi samo kao dokaz niza događaja, nego i kao dokaz da je taj niz događaja potvrđen od strane dela peer-to-peer mreže koja poseduju najveću zbirnu procesorsku snagu (CPU). Sve dok većinu procesorske snage kontrolišu čvorovi (nodes) koji ne sarađuju u napadu na mrežu, oni će generisati najduži lanac i nadmašiti napadače. Sama mreža zahteva minimalnu strukturu. Poruke kroz mrežu se prenose uz pretpostavku da svaki čvor čini maksimalan napor da poruku prenese u svom izvornom obliku i na optimalan način, a čvorovi mogu napustiti mrežu i ponovo joj se pridružiti po želji, prihvatajući najduži lanac dokaza o radu kao dokaz onoga što se dogodilo dok ih nije bilo.
1. Uvod
Trgovina na Internetu počela je da se oslanja skoro isključivo na finansijske institucije koje služe kao pouzdani posrednici pri obradi elektronskih plaćanja. Iako sistem radi dovoljno dobro za većinu transakcija i dalje trpi od inherentnih slabosti modela utemeljenog na poverenju.
Potpuno nepovratne transakcije zapravo nisu moguće, jer finansijske institucije ne mogu izbeći posredovanje u rešavanju eventualnih sporova. Troškovi posredovanja povećavaju troškove transakcija, ograničavaju minimalnu praktičnu veličinu transakcija i onemogućuju male, povremene transakcije jer postoji velika šteta zbog gubitka mogućnosti da se izvrše nepovratna plaćanja za nepovratne usluge. Uz mogućnost povraćaja transakcije, potreba za poverenjem raste. Trgovci moraju biti oprezni prema svojim kupcima i tražiti im više informacija nego što bi inače bilo neophodno. Određeni procenat prevara prihvaćen je kao neizbežan. Ovi troškovi i nepouzdanost plaćanja mogu se izbeći korišćenjem gotovine, ali ne postoji mehanizam za elektronsko plaćanje bez pouzdane treće strane.
Ono što je potrebno je elektronski sistem plaćanja zasnovan na kriptografskom dokazu umesto na poverenju, koji omogućava da bilo koje dve strane direktno i dobrovoljno međusobno trguju bez potrebe za posrednikom. Transakcije koje su nepovratne bi zaštitile prodavce od prevara, a escrow mehanizmi mogli bi se lako implementirati radi zaštite kupaca. U ovom dokumentu predlažemo rešenje problema dvostruke potrošnje korišćenjem peer-to-peer distribuiranog servera vremenskih oznaka (timestamp) za generisanje računarskog dokaza o hronološkom redosledu transakcija. Sistem je siguran sve dok pošteni čvorovi zajedno kontrolišu više procesorske snage procesora nego bilo koja udružena grupa napadačkih čvorova.
2. Transakcije
Elektronski novčić definišemo kao lanac digitalnih potpisa. Svaki vlasnik prenosi novčić na sledećeg digitalnim potpisivanjem heša prethodne transakcije i javnog ključa sledećeg vlasnika, dodajući ih potom na kraj novčića. Primalac transakcije može da verifikuje potpise, a time i lanac vlasništva.
Problem je naravno u tome što primalac ne može potvrditi da jedan od prethodnih vlasnika nije dva puta poslao isti novčić. Uobičajeno rešenje je uvođenje pouzdanog centralizovanog posrednika, kreatora novčića koji proverava sve transakcije. Nakon svake transakcije, novčić se mora vratiti kreatoru kako bi se izdao novi novčić i veruje se da samo za novčiće izdate direktno od kreatora možemo biti sigurni da nisu dva puta potrošeni. Problem sa ovim rešenjem je što sudbina čitavog novčanog sistema zavisi od kompanije koja kreira novčiće, jer svaka transakcija mora da prođe kroz nju, baš kao što je slučaj sa bankom.
Treba nam način da primalac bude siguran da prethodni vlasnici nisu potpisali nikakve ranije transakcije kojim bi potrošili taj novčić. Za naše potrebe, računamo transakciju koja se prva desila i ne zanimaju nas naredni pokušaji da se isti novčić ponovo pošalje. Jedini način da sa sigurnošću potvrdimo da taj novčić nije prethodno bio poslat je da imamo informacije o svim transakcijama koje su se ikada desile. U modelu baziranom na centalizovan kreatoru, taj kreator je imao informacije o svim transakcijama i odlučivao koja transakcija je prva stigla. Da bismo to postigli bez pouzdanog posrednika, transakcije moraju biti javno objavljene [1] i potreban nam je sistem u kojem učesnici mogu da se dogovore o jedinstvenoj istoriji redosleda kojim su transakcije primljene. Primaocu je potreban dokaz da se u trenutku dešavanja svake od transakcija većina čvorova složila oko toga da je baš ta transakcija bila ona koja je prva primljena.
3. Server vremenskih oznaka
Rešenje koje predlažemo počinje serverom vremenskih oznaka. Server vremenske oznake radi tako što uzima heš bloka podataka kojem će se dodeliti vremenska oznaka i objavi taj heš svima u mreži, slično kao u novinama ili kao post na Usenet mreži [2-5]. Vremenska oznaka očigledno dokazuje da su podaci morali postojati u to vreme kako bi ušli u haš. Svaka vremenska oznaka sadrži prethodnu vremensku oznaku u svom hešu, formirajući tako lanac, pri čemu svaka dodatna vremenska oznaka pojačava potvrde onih pre nje.
4. Dokaz o radu (Proof-of-Work)
Da bismo implementirali distribuirani server vremenskih oznaka na peer-to-peer principu, moraćemo da koristimo sistem dokaza o radu sličan Hashcash-u Adama Back-a [6], umesto Uneset postova ili novinskih objava. Dokaz o radu uključuje traženje vrednosti koja će, kada se hešuje, na primer pomoću SHA-256 heš funkcije, stvarati heš čiji binarni zapis započinje određenim brojem nula. Prosečna količina potrebnog rada eksponencijalno raste sa brojem potrebnih početnih nula, a može se proveriti izvršavanjem samo jedne heš fuknkcije.
Za našu mrežu vremenskih oznaka implementiramo dokaz o radu povećavajući nonce broja u bloku sve dok se ne pronađe ona vrednost nonce-a koja daje hešu bloka potreban broj početnih nula. Jednom kada se procesorska snaga utroši kako bi se zadovoljio dokaz o radu, blok se ne može izmeniti bez ponovljenog rada. Kako se kasniji blokovi vežu na taj blok, rad potreban da se on izmeni uključivao bi i ponovno obrađivanje svih blokova nakon njega.
Dokaz o radu takođe rešava problem utvrđivanja većine pri odlučivanju. Ako bi se većina zasnivala na principu jednog glasa po IP adresi, mogao bi je narušiti svako ko je u stanju da glasa sa više IP adresa odjednom. Dokaz o radu u osnovi predstavlja jedan glas po jedinici procesorske snage. Većinska odluka je predstavljena najdužim lancem u čije je stvaranje zapravo investirano najviše rada prilikom dokazivanja. Ako većinu procesorske snage kontrolišu pošteni čvorovi, pošten lanac će rasti najbrže i nadmašiće sve konkurentske lance. Da bi izmenio neki od prethodnih blokova, napadač bi morao da ponovi dokaz o radu za taj blok i sve blokove nakon njega, a zatim da sustigne i nadmaši količinu rada poštenih čvorova. Kasnije ćemo pokazati da se dodavanjem novih blokova eksponencijalno smanjuje verovatnoća da će sporiji napadač uspeti da sustigne pošteni lanac.
Da bi se kompenzovalo povećanje brzine hardvera i promenljivo interesovanje ljudi za vođenje čvorova tokom vremena, težina obavljanja dokaza o radu (proof-of-work difficulty) određuje se prema prosečnom broju blokova krairanih za sat vremena. Ako se blokovi stvaraju prebrzo, težina se povećava.
5. Mreža
Koraci za vođenje mreže su sledeći:
1) Nove transakcije se prosleđuju svim čvorovima u mreži. 2) Svaki čvor prikuplja nove transakcije u blok. 3) Svaki čvor radi na pronalaženju dokaza o radu dovoljnog nivoa težine za svoj blok. 4) Kada čvor pronađe dokaz o radu, on emituje taj blok ka svim čvorovima. 5) Čvorovi prihvataju blok samo ako su sve transakcije u njemu ispravne i nisu već potrošene. 6) Čvorovi izražavaju prihvatanje bloka radeći na stvaranju sledećeg bloka u lancu, koristeći heš prihvaćenog bloka kao prethodni heš.
Čvorovi uvek smatraju da je najduži lanac ispravan i nastaviće da rade na njegovom produžavanju. Ako dva čvora istovremeno emituju različite verzije sledećeg bloka, neki čvorovi prvo mogu primiti jedan ili drugi blok. U tom slučaju svaki čvor radi na prvom koji je dobio, ali čuvaju drugu kariku lanca u slučaju da ona postane duža. Dilema će biti rešena kada se pronađe sledeći dokaz o radu i jedna karika postane duža; čvorovi koji su radili na drugoj karici lanca će se prebaciti na dužu kariku.
Emitovanje novih transakcija ne mora nužno doći do svih čvorova. Sve dok stižu do velikog broja čvorova, te transakcije će ući u blok. Slično važi i za blokove, ni oni ne moraju doći odmah do svih čvorova. Ako neki čvor propusti da primi informaciju o bloku, kada mu stigne sledeći blok,primetiće da je propustio jedan, pa će ga tražiti naknadno.
6. Podsticaj
Po pravilu, prva transakcija u bloku je posebna transakcija koja kreira novi novčić u vlasništvu kreatora bloka. Ovo daje podsticaj čvorovima da podrže mrežu i pruža način za početnu ubacivanje novčića u opticaj, budući da ne postoji centralno telo koje ih izdaje. Stalno dodavanje konstantne količine novih novčića liči na rudarenje zlata, gde rudari ulažu resurse kako bi izrudarili nove količine zlata i ubacili ih u opticaj. U našem slučaju ulaže se procesorsko vreme i električna energija.
Podsticaj se takođe može finansirati i transakcionim naknadama. Ako je iznos izlaznog dela transakcije manji od ulaznog, razliku čini naknada za transakciju koja se dodaje iznosu nagrade za kreatora bloka koji sadrži tu transakciju. Nakon što predefinisani broj novčića uđe u opticaj, podsticaj mogu u potpunosti činiti transakcione naknade, čime se sistem oslobađa inflacije.
Čvorovi su na ovaj način podstaknuti da ostanu pošteni. Ako je pohlepni napadač u stanju da angažuje više procesorske snage od svih poštenih čvorova zajedno, morao bi da bira između toga da poništi svoje izvršene transakcije i time prevari ljude ili da procesorsku snagu koristi za stvaranje novih novčića. On bi trebalo bi uvidi da je isplativije igrati po pravilima koja ga nagrađuju sa više novih novčića od svi drugi zajedno, nego da potkopava sistem i vrednost sopstvenog bogatstva.
7. Oslobađanje prostora na hard disku
Kada je dovoljno blokova dodato nakon poslednje transakcije novčića, prethodne transakcije tog novčića se mogu odbaciti kako bi se uštedeo prostor na hard disku. Kako bi se to ostvarilo bez razbijanja heša bloka, transakcije su hešovane u Merkleovo stablo (Merkle Tree) [7] [2] [5], gde je samo koren uključen u heš bloka. Stari blokovi se tada mogu sabiti uklanjanjem nepotrebnih grana drveta. Unutrašnji heševi ne moraju biti skladišteni.
Zaglavlje bloka bez transakcija bilo bi oko 80 bajtova. Ako pretpostavimo da su blokovi generisani svakih 10 minuta, 80 bajtova * 6 * 24 * 365 = 4,2 MB godišnje. Imajući u vidu činjenicu da se u 2008. godini računari uglavnom prodaju sa oko 2 GB RAM-a i Murov zakon koji predviđa trenutni rast od 1,2 GB godišnje, skladištenje ne bi trebalo da predstavlja problem čak i ako se zaglavlja bloka moraju čuvati u memoriji.
8. Pojednostavljena verifikacija plaćanja
Moguće je verifikovati plaćanja bez vođenja čitavog mrežnog čvora. Korisnik samo treba da sačuva kopiju zaglavlja blokova najdužeg lanca dokaza o radu, do koje može doći upitom ka mrežnim čvorovima dok se ne uveri da je dobio najduži lanac i dobije Merkleova granu
koja povezuje transakciju sa blokom u koji je uneta vremenska oznaka za tu transakciju. Ne može samostalno proveriti transakciju, ali povezujući je sa mestom u lancu može videti da je prihvaćena od strane čvora mreže i da su na njen blok dodati naknadni blokovi što dalje potvrđuje da ju je mreža prihvatila.
Kao takva, verifikacija je pouzdana sve dok pošteni čvorovi kontrolišu mrežu, ali je ranjiva ako napadač nadjača ostatak mreže. Čvorovi mreže mogu sami proveriti transakcije, ali napadačeve lažne transakcije mogu zavarati one koji koriste pojednostavljenu metodu verifikacije transakcija sve dok je on u stanju da nadjačava ostatak mreže. Jedna od strategija zaštite bila bi prihvatanje upozorenja čvorova mreže kada otkriju nevažeći blok, pri čemu bi korisnikov softver morao da preuzme ceo blok i sporne transakcije kako bi potvrdio nepravilnost. Biznisi koji primaju česte uplate će verovatno želeti da pokrenu i vode sopstvene čvorove radi brže verifikacije i potrebe da im sigurnost ne zavisi od drugih.
9. Kombinovanje i deljenje vrednosti
Iako bi bilo moguće pojedinačno rukovati novčićima, bilo bi nezgrapno kreirati zasebnu transakciju za svaki cent u toj transferu. Da biste dozvolili podelu i kombinovanje vrednosti, transakcije sadrže više ulaza i izlaza. Obično će postojati ili jedan ulaz iz veće prethodne transakcije ili više unosa koji kombinuju manje iznose, a najviše dva izlaza: jedan za samo plaćanje, a jedan koji vraća kusur, ako ga ima, nazad pošiljaocu.
Treba napomenuti da situacija u kojoj transakcija zavisi od nekoliko drugih transakcija, a te transakcije zavise od još mnogo više, ovde nije problem. Nikada ne postoji potreba za izdvajanjem istorije pojedinačne transakcije.
10. Privatnost
Tradicionalni bankarski model postiže odgovarajući nivo privatnosti ograničavanjem pristupa informacijama na strane uključene u transakciju i posrednika. Neophodnost javnog objavljivanja svih transakcija isključuje mogućnost primene pomenutog modela, ali privatnost se i dalje može zadržati na drugi način: čuvanjem javnih ključeva (public keys) anonimnim. Javnost može videti da neko šalje iznos nekom drugom, ali bez informacija koje povezuju transakciju sa bilo kim. Ovo je slično količini informacija koje objavljuju berze, gde se vreme i veličina pojedinačnih trgovina čine javnim, ali bez navođenja ko su stranke uključene u tu trgovinu.
Kao dodatni zaštitni zid, preporučljivo je koristiti novi par ključeva za svaku transakciju, kako ne bi bili povezane sa zajedničkim vlasnikom. Neka povezivanja su i dalje neizbežna kod transakcija sa više ulaza, koje nužno otkrivaju da su njihovi ulazi bili u vlasništvu istog vlasnika. Rizik je taj da bi se otkrivanjem vlasnik ključa mogle otkriti i ostale transakcije koje su pripadale tom vlasniku.
11. Proračuni
Razmatramo scenario u kome napadač pokušava da generiše alternativni lanac brže od poštenog lanca. Čak i ako se to postigne, to ne omogućuje proizvoljne promene u sistemu, poput stvaranje vrednosti ni iz čega ili uzimanje novca koji nikada nije pripadao napadaču. Pošteni čvorovi neće prihvatiti nevažeće transakcije kao uplatu i nikada neće prihvatiti blok koji ih sadrži. Napadač može samo pokušati da promeni jednu od svojih transakcija kako bi vratio novac koji je nedavno potrošio.
Trka između poštenog lanca i lanca napadača može se predstaviti kao binomska distribucija slučajne diskretne varijable (Binomial Random Walk). Uspešni ishod je da se pošten lanac produži za jedan blok, povećavajući svoje vođstvo za +1, a neuspešni ishod je da se napadačev lanac produži za jedan blok, smanjujući zaostatak za -1.
Verovatnoću da napadač nadoknadi određeni deficit možemo izraziti kroz problem kockareve propasti (Gambler’s Ruin Problem). Pretpostavimo da kockar sa neograničenim iznosom novca počinje sa zaostatkom i igra potencijalno beskonačan broj ponovljenih igara u pokušaju da nadoknadi zaostatak. Možemo izračunati verovatnoću za nadoknađivanje zaostatka ili da će napadač stići pošten lanac, na sledeći način [8]:
p= verovatnoća da pošten čvor pronađe sledeći blok q= verovatnoća da napadač pronađe sledeći blok qz= verovatnoća da će napadač ikada dostići z blokova zaostatka
S obzirom na našu pretpostavku da je p > q, verovatnoća pada eksponencijalno kako se povećava broj blokova koje napadač mora da nadoknadi. Sa šansama protiv njega, ako mu se u početku ne posreći, njegove šanse postaju manje i manje sa povećanjem zaostatka.
Sada razmatramo koliko primalac nove transakcije treba da čeka pre nego što postane
dovoljno siguran da pošiljalac ne može promeniti transakciju. Pretpostavljamo da je pošiljalac napadač koji želi da natera primaoca da veruje da mu je platio, a zatim nakon nekog vremena tu transakciju preusmeri ka sebi. Primalac će primetiti kada se to dogodi, ali pošiljalac se nada da će tad već biti prekasno.
Primalac generiše novi par ključeva i daje javni ključ pošiljaocu neposredno pre potpisivanja transakcije. Ovo sprečava pošiljaoca da unapred pripremi lanac blokova radeći na njemu neprekidno dok mu se ne posreći da stekne dovoljnu prednost i u tom trenutku izvrši transakciju. Kada se transakcija pošalje, nepošteni pošiljalac počinje tajno da radi na paralelnom lancu koji sadrži alternativnu verziju njegove transakcije.
Primalac čeka dok transakcija ne bude dodata u blok, i dok z blokova nije dodato nakon tog bloka. On ne zna tačno koliko je napadač napredovao, ali pod pretpostavkom da su pošteni blokovi kreirani očekivanom dinamikom, potencijalni napredak napadača će biti prikazan kao Poasonova distribucija sa očekivanom vrednošću:
Kako bismo izračunali verovatnoću da napadač ipak može da nadoknadi zaostatak, množimo gustinu verovatnoće za svaki nivo napretka koji je mogao da ostvari sa verovatnoćom da od tog trenutka može da potpuno nadoknadi zaostatak:
Preuređujemo formulu kako bismo izbegli sabiranje beskonačnog broja sabiraka zbog repa distribucije:

12. Zaključak
Predložili smo sistem za elektronske transakcije bez oslanjanja na poverenje. Počeli smo sa uobičajenim šablonom i novčićima nastalim iz digitalnih potpisa, koji pruža snažnu kontrolu nad vlasništvom, ali je nepotpun bez načina da se spreči dvostruka potrošnja. Kako bismo ovo rešili, predložili smo peer-to-peer mrežu koja koristi dokaz o radu za čuvanje javne istorije transakcija čija izmena napadačima brzo postaje računski nepraktična ako pošteni čvorovi kontrolišu većinu procesorske snage. Mreža je robusna u svojoj nestrukturiranoj jednostavnosti. Svi čvorovi rade istovremeno uz malo koordinacije. Ne treba ih identifikovati, jer se poruke ne usmeravaju na jedno određeno mesto nego samo trebaju biti prenete uz maksimalan napor od strane čvorova da se taj prenos odradi na predviđen način. Čvorovi mogu da napuste i ponovo se pridruže mreži po želji, prihvatajući lanac dokaza o radu kao dokaz onoga što se dogodilo dok ih nije bilo. Oni glasaju svojom procesorskom snagom, izražavajući svoje prihvatanje validnih blokova time što pokušavaju da ih nadgrade novim blokovima i odbacuju nevažeće blokove odbijanjem ih nadgrađuju. Sva potrebna pravila i podsticaji mogu se nametnuti ovim mehanizmom postizanja konsenzusa.

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

2024-12-22 21:35:22I’ll admit that I was wrong about Bitcoin. Perhaps in 2013. Definitely 2017. Probably in 2018-2019. And maybe even today.
Being wrong about Bitcoin is part of finally understanding it. It will test you, make you question everything, and in the words of BTC educator and privacy advocate Matt Odell, “Bitcoin will humble you”.
I’ve had my own stumbles on the way.
In a very public fashion in 2017, after years of using Bitcoin, trying to start a company with it, using it as my primary exchange vehicle between currencies, and generally being annoying about it at parties, I let out the bear.
In an article published in my own literary magazine Devolution Review in September 2017, I had a breaking point. The article was titled “Going Bearish on Bitcoin: Cryptocurrencies are the tulip mania of the 21st century”.
It was later republished in Huffington Post and across dozens of financial and crypto blogs at the time with another, more appropriate title: “Bitcoin Has Become About The Payday, Not Its Potential”.
As I laid out, my newfound bearishness had little to do with the technology itself or the promise of Bitcoin, and more to do with the cynical industry forming around it:
In the beginning, Bitcoin was something of a revolution to me. The digital currency represented everything from my rebellious youth.
It was a decentralized, denationalized, and digital currency operating outside the traditional banking and governmental system. It used tools of cryptography and connected buyers and sellers across national borders at minimal transaction costs.
…
The 21st-century version (of Tulip mania) has welcomed a plethora of slick consultants, hazy schemes dressed up as investor possibilities, and too much wishy-washy language for anything to really make sense to anyone who wants to use a digital currency to make purchases.
While I called out Bitcoin by name at the time, on reflection, I was really talking about the ICO craze, the wishy-washy consultants, and the altcoin ponzis.
What I was articulating — without knowing it — was the frame of NgU, or “numbers go up”. Rather than advocating for Bitcoin because of its uncensorability, proof-of-work, or immutability, the common mentality among newbies and the dollar-obsessed was that Bitcoin mattered because its price was a rocket ship.
And because Bitcoin was gaining in price, affinity tokens and projects that were imperfect forks of Bitcoin took off as well.
The price alone — rather than its qualities — were the reasons why you’d hear Uber drivers, finance bros, or your gym buddy mention Bitcoin. As someone who came to Bitcoin for philosophical reasons, that just sat wrong with me.
Maybe I had too many projects thrown in my face, or maybe I was too frustrated with the UX of Bitcoin apps and sites at the time. No matter what, I’ve since learned something.
I was at least somewhat wrong.
My own journey began in early 2011. One of my favorite radio programs, Free Talk Live, began interviewing guests and having discussions on the potential of Bitcoin. They tied it directly to a libertarian vision of the world: free markets, free people, and free banking. That was me, and I was in. Bitcoin was at about $5 back then (NgU).
I followed every article I could, talked about it with guests on my college radio show, and became a devoted redditor on r/Bitcoin. At that time, at least to my knowledge, there was no possible way to buy Bitcoin where I was living. Very weak.
I was probably wrong. And very wrong for not trying to acquire by mining or otherwise.
The next year, after moving to Florida, Bitcoin was a heavy topic with a friend of mine who shared the same vision (and still does, according to the Celsius bankruptcy documents). We talked about it with passionate leftists at Occupy Tampa in 2012, all the while trying to explain the ills of Keynesian central banking, and figuring out how to use Coinbase.
I began writing more about Bitcoin in 2013, writing a guide on “How to Avoid Bank Fees Using Bitcoin,” discussing its potential legalization in Germany, and interviewing Jeremy Hansen, one of the first political candidates in the U.S. to accept Bitcoin donations.
Even up until that point, I thought Bitcoin was an interesting protocol for sending and receiving money quickly, and converting it into fiat. The global connectedness of it, plus this cypherpunk mentality divorced from government control was both useful and attractive. I thought it was the perfect go-between.
But I was wrong.
When I gave my first public speech on Bitcoin in Vienna, Austria in December 2013, I had grown obsessed with Bitcoin’s adoption on dark net markets like Silk Road.
My theory, at the time, was the number and price were irrelevant. The tech was interesting, and a novel attempt. It was unlike anything before. But what was happening on the dark net markets, which I viewed as the true free market powered by Bitcoin, was even more interesting. I thought these markets would grow exponentially and anonymous commerce via BTC would become the norm.
While the price was irrelevant, it was all about buying and selling goods without permission or license.
Now I understand I was wrong.
Just because Bitcoin was this revolutionary technology that embraced pseudonymity did not mean that all commerce would decentralize as well. It did not mean that anonymous markets were intended to be the most powerful layer in the Bitcoin stack.
What I did not even anticipate is something articulated very well by noted Bitcoin OG Pierre Rochard: Bitcoin as a savings technology.
The ability to maintain long-term savings, practice self-discipline while stacking stats, and embrace a low-time preference was just not something on the mind of the Bitcoiners I knew at the time.
Perhaps I was reading into the hype while outwardly opposing it. Or perhaps I wasn’t humble enough to understand the true value proposition that many of us have learned years later.
In the years that followed, I bought and sold more times than I can count, and I did everything to integrate it into passion projects. I tried to set up a company using Bitcoin while at my university in Prague.
My business model depended on university students being technologically advanced enough to have a mobile wallet, own their keys, and be able to make transactions on a consistent basis. Even though I was surrounded by philosophically aligned people, those who would advance that to actually put Bitcoin into practice were sparse.
This is what led me to proclaim that “Technological Literacy is Doomed” in 2016.
And I was wrong again.
Indeed, since that time, the UX of Bitcoin-only applications, wallets, and supporting tech has vastly improved and onboarded millions more people than anyone thought possible. The entrepreneurship, coding excellence, and vision offered by Bitcoiners of all stripes have renewed a sense in me that this project is something built for us all — friends and enemies alike.
While many of us were likely distracted by flashy and pumpy altcoins over the years (me too, champs), most of us have returned to the Bitcoin stable.
Fast forward to today, there are entire ecosystems of creators, activists, and developers who are wholly reliant on the magic of Bitcoin’s protocol for their life and livelihood. The options are endless. The FUD is still present, but real proof of work stands powerfully against those forces.
In addition, there are now dozens of ways to use Bitcoin privately — still without custodians or intermediaries — that make it one of the most important assets for global humanity, especially in dictatorships.
This is all toward a positive arc of innovation, freedom, and pure independence. Did I see that coming? Absolutely not.
Of course, there are probably other shots you’ve missed on Bitcoin. Price predictions (ouch), the short-term inflation hedge, or the amount of institutional investment. While all of these may be erroneous predictions in the short term, we have to realize that Bitcoin is a long arc. It will outlive all of us on the planet, and it will continue in its present form for the next generation.
Being wrong about the evolution of Bitcoin is no fault, and is indeed part of the learning curve to finally understanding it all.
When your family or friends ask you about Bitcoin after your endless sessions explaining market dynamics, nodes, how mining works, and the genius of cryptographic signatures, try to accept that there is still so much we have to learn about this decentralized digital cash.
There are still some things you’ve gotten wrong about Bitcoin, and plenty more you’ll underestimate or get wrong in the future. That’s what makes it a beautiful journey. It’s a long road, but one that remains worth it.
