Private property isn’t lines on dirt or fences of steel—it’s the crystallization of human sovereignty. Each boundary drawn is a silent declaration: This is where my will meets yours, where creation clashes against chaos. What we defend as “mine” or “yours” is no mere object but a metaphysical claim, a scaffold for the unfathomable complexity of voluntary exchange.

Markets breathe only when individuals anchor their choices in the inviolable. Without property, there is no negotiation—only force. No trade—only taking. The deed to land, the title to a car, the seed of an idea: these are not static things but frontiers of being, where human responsibility collides with the infinite permutations of value.

Austrian economics whispers what existentialism shouts: existence precedes essence. Property isn’t granted by systems; it’s asserted through action, defended through sacrifice, and sanctified through mutual recognition. A thing becomes “owned” only when a mind declares it so, and others—through reason or respect—refrain from crossing that unseen line.

Bitcoin? The purest ledger of this truth. A string of code, yes—but one that mirrors the unyielding logic of property itself: scarce, auditable, unconquerable. It doesn’t ask permission. It exists because sovereign minds choose it to.

Sigh. #nostr
I love #Bitcoin.

¿Qué es Blossom?

nostr:nevent1qqspttj39n6ld4plhn4e2mq3utxpju93u4k7w33l3ehxyf0g9lh3f0qpzpmhxue69uhkummnw3ezuamfdejsygzenanl0hmkjnrq8fksvdhpt67xzrdh0h8agltwt5znsmvzr7e74ywgmr72

Blossom significa Blobs Simply Stored on Media Servers (Blobs Simplemente Almacenados en Servidores de Medios). Blobs son fragmentos de datos binarios, como archivos pero sin nombres. En lugar de nombres, se identifican por su hash sha256. La ventaja de usar hashes sha256 en lugar de nombres es que los hashes son IDs universales que se pueden calcular a partir del archivo mismo utilizando el algoritmo de hash sha256.

💡 archivo -> sha256 -> hash

Blossom es, por lo tanto, un conjunto de puntos finales HTTP que permiten a los usuarios almacenar y recuperar blobs almacenados en servidores utilizando su identidad nostr.

¿Por qué Blossom?

Como mencionamos hace un momento, al usar claves nostr como su identidad, Blossom permite que los datos sean "propiedad" del usuario. Esto simplifica enormemente la cuestión de "qué es spam" para el alojamiento de servidores. Por ejemplo, en nuestro Blossom solo permitimos cargas por miembros de la comunidad verificados que tengan un NIP-05 con nosotros.

Los usuarios pueden subir en múltiples servidores de blossom, por ejemplo, uno alojado por su comunidad, uno de pago, otro público y gratuito, para establecer redundancia de sus datos. Los blobs pueden ser espejados entre servidores de blossom, de manera similar a cómo los relays nostr pueden transmitir eventos entre sí. Esto mejora la resistencia a la censura de blossom.

A continuación se muestra una breve tabla de comparación entre torrents, Blossom y servidores CDN centralizados. (Suponiendo que hay muchos seeders para torrents y se utilizan múltiples servidores con Blossom).

| | Torrents | Blossom | CDN Centralizado | | --------------------------------------------------------------- | -------- | ------- | ---------------- | | Descentralizado | ✅ | ✅ | ❌ | | Resistencia a la censura | ✅ | ✅ | ❌ | | ¿Puedo usarlo para publicar fotos de gatitos en redes sociales? | ❌ | ✅ | ✅ |

¿Cómo funciona?

Blossom utiliza varios tipos de eventos nostr para comunicarse con el servidor de medios.

| kind | descripción | BUD | | ----- | ------------------------------- | ------------------------------------------------------------------ | | 24242 | Evento de autorización | BUD01 | | 10063 | Lista de Servidores de Usuarios | BUD03 |

kind:24242 - Autorización

Esto es esencialmente lo que ya describimos al usar claves nostr como IDs de usuario. En el evento, el usuario le dice al servidor que quiere subir o eliminar un archivo y lo firma con sus claves nostr. El servidor realiza algunas verificaciones en este evento y luego ejecuta el comando del usuario si todo parece estar bien.

kind:10063 - Lista de Servidores de Usuarios

Esto es utilizado por el usuario para anunciar a qué servidores de medios está subiendo. De esta manera, cuando el cliente ve esta lista, sabe dónde subir los archivos del usuario. También puede subir en múltiples servidores definidos en la lista para asegurar redundancia. En el lado de recuperación, si por alguna razón uno de los servidores en la lista del usuario está fuera de servicio, o el archivo ya no se puede encontrar allí, el cliente puede usar esta lista para intentar recuperar el archivo de otros servidores en la lista. Dado que los blobs se identifican por sus hashes, el mismo blob tendrá el mismo hash en cualquier servidor de medios. Todo lo que el cliente necesita hacer es cambiar la URL por la de un servidor diferente.

Ahora, además de los conceptos básicos de cómo funciona Blossom, también hay otros tipos de eventos que hacen que Blossom sea aún más interesante.

| kind | descripción | | ----- | --------------------- | | 30563 | Blossom Drives | | 36363 | Listado de Servidores | | 31963 | Reseña de Servidores |

kind:30563 - Blossom Drives

Este tipo de evento facilita la organización de blobs en carpetas, como estamos acostumbrados con los drives (piensa en Google Drive, iCloud, Proton Drive, etc.). El evento contiene información sobre la estructura de carpetas y los metadatos del drive.

kind:36363 y kind:31963 - Listado y Reseña

Estos tipos de eventos permiten a los usuarios descubrir y reseñar servidores de medios a través de nostr. kind:36363 es un listado de servidores que contiene la URL del servidor. kind:31963 es una reseña, donde los usuarios pueden calificar servidores.

¿Cómo lo uso?

Encuentra un servidor

Primero necesitarás elegir un servidor Blossom donde subirás tus archivos. Puedes navegar por los públicos en blossomservers.com. Algunos de ellos son de pago, otros pueden requerir que tus claves nostr estén en una lista blanca.

Luego, puedes ir a la URL de su servidor y probar a subir un archivo pequeño, como una foto. Si estás satisfecho con el servidor (es rápido y aún no te ha fallado), puedes agregarlo a tu Lista de Servidores de Usuarios. Cubriremos brevemente cómo hacer esto en noStrudel y Amethyst (pero solo necesitas hacer esto una vez, una vez que tu lista actualizada esté publicada, los clientes pueden simplemente recuperarla de nostr).

noStrudel
1. Encuentra Relays en la barra lateral, luego elige Servidores de Medios.
2. Agrega un servidor de medios, o mejor aún, varios.
3. Publica tu lista de servidores. ✅
Amethyst
1. En la barra lateral, encuentra Servidores multimedia.
2. Bajo Servidores Blossom, agrega tus servidores de medios.
3. Firma y publica. ✅
Ahora, cuando vayas a hacer una publicación y adjuntar una foto, por ejemplo, se subirá en tu servidor blossom.

⚠️ Ten en cuenta que debes suponer que los archivos que subas serán públicos. Aunque puedes proteger un archivo con contraseña, esto no ha sido auditado.

Blossom Drive

Como mencionamos anteriormente, podemos publicar eventos para organizar nuestros blobs en carpetas. Esto puede ser excelente para compartir archivos con tu equipo, o simplemente para mantener las cosas organizadas.

Para probarlo, ve a blossom.hzrd149.com (o nuestra instancia comunitaria en blossom.bitcointxoko.com) e inicia sesión con tu método preferido.

Puedes crear una nueva unidad y agregar blobs desde allí.

Bouquet

Si usas múltiples servidores para darte redundancia, Bouquet es una buena manera de obtener una visión general de todos tus archivos. Úsalo para subir y navegar por tus medios en diferentes servidores y sincronizar blobs entre ellos.

Cherry Tree

nostr:nevent1qvzqqqqqqypzqfngzhsvjggdlgeycm96x4emzjlwf8dyyzdfg4hefp89zpkdgz99qyghwumn8ghj7mn0wd68ytnhd9hx2tcpzfmhxue69uhkummnw3e82efwvdhk6tcqyp3065hj9zellakecetfflkgudm5n6xcc9dnetfeacnq90y3yxa5z5gk2q6

Cherry Tree te permite dividir un archivo en fragmentos y luego subirlos en múltiples servidores blossom, y más tarde reensamblarlos en otro lugar.

Conclusión

Blossom aún está en desarrollo, pero ya hay muchas cosas interesantes que puedes hacer con él para hacerte a ti y a tu comunidad más soberanos. ¡Pruébalo!

Si deseas mantenerte al día sobre el desarrollo de Blossom, sigue a nostr:nprofile1qyghwumn8ghj7mn0wd68ytnhd9hx2tcpzfmhxue69uhkummnw3e82efwvdhk6tcqyqnxs90qeyssm73jf3kt5dtnk997ujw6ggy6j3t0jjzw2yrv6sy22ysu5ka y dale un gran zap por su excelente trabajo.

I 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:
  1. 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.
  2. 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."

Scuttlebutt 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.

Scuttlebot

O software Pub é conhecido como servidor Scuttlebutt (servidor ssb ), mas também é conhecido como “Scuttlebot” e sbotna linha de comando. O servidor SSB adiciona comportamento de rede ao banco de dados Scuttlebutt (SSB). Estaremos usando o Scuttlebot ao longo deste tutorial.

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.

GUI - Interface Gráfica do Utilizador(Usuário)

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 .

Another good day, but not quite on par with yesterday. I'm sipping some coffee, after 16 hours dry fasting. I'm not really hungry yet, so I'll probably go a while longer before I eat.

Yesterday was the first day that I really noticed the different taste in my mouth that indicates ketosis. Interestingly, it lasted all day. I figured it would wane after I ate a bunch of pasta.

Another thing I've noticed is that I'm more interested in eating fresh produce than normal. A side benefit of dry fasting might be that juicier foods become more appealing.

Score Card

Day 1: 14 hour fast (13 dry) Day 2: 15 hour fast (14 dry) Day 3: 17 hours (16 dry) Day 4: 18 hours (17 dry) Day 5: TBD (16 dry)

I'm also on day 3 of a Workit 10k steps/day challenge. So far so good.

A Indústria Pornográfica se caracteriza pelo investimento pesado de grandes empresários americanos, desde 2014.

Na década de 90, filmes pornográficos eram feitos às coxas. Era basicamente duas pessoas fazendo sexo amador e sendo gravadas. Não tinha roteiro, nem produção, não tinha maquiagem, nada disso. A distribuição era rudimentar, os assinantes tinham que sair de suas casas, ir até a locadora, sofrer todo tipo de constrangimento para assistir a um filme pornô.

No começo dos anos 2000, o serviço de Pay Per View fez o número de vendas de filmes eróticos (filme erótico é bem mais leve) crescer mas nada se compara com os sites de filmes pornográficos por assinatura.

Com o advento dos serviços de Streaming, os sites que vendem filmes por assinatura se estabeleceram no mercado como nunca foi visto na história.

Hoje, os Produtores usam produtos para esticar os vasos sanguíneos do pênis dos atores e dopam as atrizes para que elas aguentem horas de gravação (a Série Black Mirror fez uma crítica a isso no episódio 1 milhão de méritos de forma sutil).

Além de toda a produção em volta das cenas. Que são gravadas em 4K, para focar bem as partes íntimas dos atores. Quadros fechados, iluminação, tudo isso faz essa Indústria ser "Artística" uma vez que tudo ali é falso. Um filme da Produtora Vixen, por exemplo, onde jovens mulheres transam em mansões com seus empresários estimula o esteriótipo da mina padrão que chama seu chefe rico de "daddy" e seduz ele até ele trair a esposa.

Sites como xvídeos, pornHub e outros nada mais são do que sites que salvam filmes dessas produtoras e hospedam as cenas com anúncios e pop-ups. Alguns sites hospedam o filme inteiro "de graça".

Esse tipo de filme estimula qualquer homem heterosexual com menos de 30 anos, que não tem o córtex frontal de seu cérebro totalmente desenvolvido (segundo estudos só é completamente desenvolvido quando o homem chega aos 31 anos).

A arte Pornográfica faz alguns fantasiarem ter relação sexual com uma gostosa americana branquinha, até escraviza-los. Muitos não conseguem sair do vício e preferem a Ficção à sua esposa real. Então pare de se enganar e admita. A Pornografia faz mal para a saúde mental do homem.

Quem sonha em ter uma transa com Lana Rhodes, deve estar nesse estágio. Trata-se de uma atriz (pornstar) que ganhou muito dinheiro vendendo a ilusão da Arte Pornografica, como a Riley Reid que só gravava para grandes Produtoras. Ambas se arrependeram da carreira artística e agora tentam viver suas vidas como uma mulher comum.

As próprias atrizes se consideram artistas, como Mia Malkova, chegou a dizer que Pornografia é a vida dela, que é "Lindo e Sofisticado."

Mia Malkova inclusive faz questão de dizer que a industria não escravisa mulheres jovens. Trata-se de um negócio onde a mulher assina um contrato com uma produtora e recebe um cachê por isso. Diferente do discurso da Mia Khalifa em entrevista para a BBC, onde diz que as mulheres são exploradas por homens poderosos. Vai ela está confundindo o Conglomerado Vixen com a Rede Globo ou com a empresa do Harvey Weinstein.

Enfim, se você é um homem solteiro entre 18 e 40 anos que já consumiu ou que ainda consome pornografia, sabia que sofrerá consequências. Pois trata-se de "produções artísticas" da indústria audiovisual que altera os níveis de dopamina do seu cérebro, mudando a neuroplasticidade e diminuindo a massa cinzenta, deixando o homem com memória fraca, sem foco e com mente nebulosa.

Por que o Estado não proíbe/criminaliza a Pornografia se ela faz mal? E desde quando o Estado quer o nosso bem? Existem grandes empresarios que financiam essa indústria ajudando governos a manterem o povo viciado e assim alienado. É um pão e circo, só que muito mais viciante e maléfico. Eu costume dizer aos meus amigos que existem grandes empresários jvdeus que são donos de grandes Produtoras de filmes pornográficos como o Conglomerado Vixen. Então se eles assistem vídeos pirateados de filmes dessas produtoras, eles estão no colo do Judeu.

Im Augenblick wird mit größter Intensität, großer Umsicht \ das deutsche Volk belogen. \ Olaf Scholz im FAZ-Interview

Online-Wahlen stärken die Demokratie, sind sicher, und 61 Prozent der Wahlberechtigten sprechen sich für deren Einführung in Deutschland aus. Das zumindest behauptet eine aktuelle Umfrage, die auch über die Agentur Reuters Verbreitung in den Medien gefunden hat. Demnach würden außerdem 45 Prozent der Nichtwähler bei der Bundestagswahl ihre Stimme abgeben, wenn sie dies zum Beispiel von Ihrem PC, Tablet oder Smartphone aus machen könnten.

Die telefonische Umfrage unter gut 1000 wahlberechtigten Personen sei repräsentativ, behauptet der Auftraggeber – der Digitalverband Bitkom. Dieser präsentiert sich als eingetragener Verein mit einer beeindruckenden Liste von Mitgliedern, die Software und IT-Dienstleistungen anbieten. Erklärtes Vereinsziel ist es, «Deutschland zu einem führenden Digitalstandort zu machen und die digitale Transformation der deutschen Wirtschaft und Verwaltung voranzutreiben».

Durchgeführt hat die Befragung die Bitkom Servicegesellschaft mbH, also alles in der Familie. Die gleiche Erhebung hatte der Verband übrigens 2021 schon einmal durchgeführt. Damals sprachen sich angeblich sogar 63 Prozent für ein derartiges «Demokratie-Update» aus – die Tendenz ist demgemäß fallend. Dennoch orakelt mancher, der Gang zur Wahlurne gelte bereits als veraltet.

Die spanische Privat-Uni mit Globalisten-Touch, IE University, berichtete Ende letzten Jahres in ihrer Studie «European Tech Insights», 67 Prozent der Europäer befürchteten, dass Hacker Wahlergebnisse verfälschen könnten. Mehr als 30 Prozent der Befragten glaubten, dass künstliche Intelligenz (KI) bereits Wahlentscheidungen beeinflusst habe. Trotzdem würden angeblich 34 Prozent der unter 35-Jährigen einer KI-gesteuerten App vertrauen, um in ihrem Namen für politische Kandidaten zu stimmen.

Wie dauerhaft wird wohl das Ergebnis der kommenden Bundestagswahl sein? Diese Frage stellt sich angesichts der aktuellen Entwicklung der Migrations-Debatte und der (vorübergehend) bröckelnden «Brandmauer» gegen die AfD. Das «Zustrombegrenzungsgesetz» der Union hat das Parlament heute Nachmittag überraschenderweise abgelehnt. Dennoch muss man wohl kein ausgesprochener Pessimist sein, um zu befürchten, dass die Entscheidungen der Bürger von den selbsternannten Verteidigern der Demokratie künftig vielleicht nicht respektiert werden, weil sie nicht gefallen.

Bundesweit wird jetzt zu «Brandmauer-Demos» aufgerufen, die CDU gerät unter Druck und es wird von Übergriffen auf Parteibüros und Drohungen gegen Mitarbeiter berichtet. Sicherheitsbehörden warnen vor Eskalationen, die Polizei sei «für ein mögliches erhöhtes Aufkommen von Straftaten gegenüber Politikern und gegen Parteigebäude sensibilisiert».

Der Vorwand «unzulässiger Einflussnahme» auf Politik und Wahlen wird als Argument schon seit einiger Zeit aufgebaut. Der Manipulation schuldig befunden wird neben Putin und Trump auch Elon Musk, was lustigerweise ausgerechnet Bill Gates gerade noch einmal bekräftigt und als «völlig irre» bezeichnet hat. Man stelle sich die Diskussionen um die Gültigkeit von Wahlergebnissen vor, wenn es Online-Verfahren zur Stimmabgabe gäbe. In der Schweiz wird «E-Voting» seit einigen Jahren getestet, aber wohl bisher mit wenig Erfolg.

Die politische Brandstiftung der letzten Jahre zahlt sich immer mehr aus. Anstatt dringende Probleme der Menschen zu lösen – zu denen auch in Deutschland die weit verbreitete Armut zählt –, hat die Politik konsequent polarisiert und sich auf Ausgrenzung und Verhöhnung großer Teile der Bevölkerung konzentriert. Basierend auf Ideologie und Lügen werden abweichende Stimmen unterdrückt und kriminalisiert, nicht nur und nicht erst in diesem Augenblick. Die nächsten Wochen dürften ausgesprochen spannend werden.

GitCitadel Development Operations

We, at GitCitadel, have been updating, moving, and rearranging our servers, for quite some time. As a rather large, complex, sprawling project, we have the infrastructure setup to match, so we've decided to give you all a quick run-down of what we are doing behind-the-scenes.

Supplier Coordination

Our first task, this week, was figuring out who would host what where. We have four different locations, where our infra is stored and managed, including two locations from our suppliers. We got that straightened out, quickly, and it's all slowly coming together and being connected and networked. Exciting to watch our DevOps landscape evolve and all of the knowledge-transfer that the interactions provide.

OneDev Implementation

Our biggest internal infra project this week was the migration of all of our issues from Jira, build scripts from Jenkins, and repos from GitHub to a self-hosted OneDev instance. In the future, all of our internal build, test, issue, patch/PR, etc. effort will take place there. We also have a separate repo there for communicating with external developers and suppliers.

Our team's GitHub projects will be demoted to mirrors and a place for external devs to PR to. Public issues and patches will continue to be managed over our self-hosted GitWorkshop instance.

We're especially glad to finally escape the GitHub Gulag, and avoid being bled dry by Jira fees, without having to give up the important features that we've come to know and love. So, yay!

Next Infrasteps

Automated Testing

Now, that we have everything tied up in one, neat, backed-up package, we can finally move on to the nitty-gritty and the dirty work. So, we're rolling up our sleeves and writing the Selenium smoke test for our Alexandria client. We'll be running that in Docker containers containing different "typical Nostr" images, such as Chrome browser with Nostr Connect signing extension, or Firefox browser with Nos2x-fox extension. Once we get the Nsec Bunker and Amber logins going, we'll add test cases and images for them, as well. (Yes, we can do Bunker. I hope you are in awe at our powers).

We are also designing an automated infrastructure test, that will simply rattle through all the various internal and external websites and relays, to make sure that everything is still online and responsive.

After that, a Gherkin-based Behave feature test for Alexandria is planned, so that we can prevent regression of completed functionality, from one release to the next.

The Gherkin scenarios are written and attached to our stories before development begins (we use acceptance tests as requirements), a manual test-execution is then completed, in order to set the story to Done. These completed scenarios will be automated, following each release, with the resulting script linked to from the origin story.

Automated Builds

As the crowning glory of every DevOps tool chain stands the build automation. This is where everything gets tied together, straightened out, configured, tested, measured, and -- if everything passes the quality gates -- released. I don't have to tell you how much time developers spend staring at the build process display, praying that it all goes through and they can celebrate a Green Wave.

We are currently designing the various builds, but the ones we have defined for the Alexandria client will be a continuous delivery pipeline, like so:

This will make it easier for us to work and collaborate asynchronously and without unnecessary delays.

Expanding the Status Page

And, finally, we get to the point of all of this busyness: reporting.

We are going to have beautiful reports, and we are going to post them online, on our status page. We will use bots, to inform Nostriches of the current status of our systems, so go ahead and follow our GitCitadel DevOps npub, to make sure you don't miss out on the IT action.

Building on stone

All in all, we're really happy with the way things are humming along, now, and the steady increase in our productivity, as all the foundational work we've put in starts to pay off. It's getting easier and easier to add new team members, repos, or features/fixes, so we should be able to scale up and out from here. Our GitCitadel is built on a firm foundation.

Happy building!

Common psychological biases that bitcoiners have

Excerpt

One of the primary reasons I got involved with markets is my interest in psychology. Humans are a fickle bunch, and it's fascinating to observe the human condition in such a clear, mathematical way.

The African sun is warming things up here at Kilimanjaro, but there's still a crispness in the morning air. My fleece jacket came in handy after a refreshing shower! I started my day with a perfect combo: coffee and breakfast on the rooftop, with a stunning view as my backdrop.

Speaking of tech, today was dedicated to getting my workspace set up. First on the agenda: Thunderbird, my trusty email client from my Linux days. It took a few hours to wrangle everything, especially the S/MIME encryption. Feeling a bit lost in the weeds, I decided to switch gears and embrace OpenPGP for end-to-end encryption – a simpler solution in my opinion.

Just as I finished conquering Thunderbird, Kilimanjaro itself decided to make an appearance! The clouds parted to reveal the majestic peak, and I couldn't resist capturing the moment with a couple of photos.

Today's another day with no set plans, just taking things minute by minute. Soaking up the beautiful scenery, the cool mornings, and the positive vibes. As soon as my foot heals, I'll be out exploring the town, snapping photos, and enjoying a delicious coffee at a local cafe.

Speaking of exploring, the world of NFTs has piqued my interest. I have a few on Opensea and WAX Blockchain, but I'm curious – where else are people showcasing their digital art? Let me know in the comments where you buy and sell your NFTs, or if they're just patiently waiting for a better future. I'd love to hear your NFT stories!

Life has a way of taking us on unexpected journeys. So, here's to embracing the unexpected, making the most of each situation, and maybe even finding a small online job to boost my budget. Wishing you all a wonderful day – and remember, don't stress yourself!

Menschen tun alles, egal wie absurd, \ um ihrer eigenen Seele nicht zu begegnen. \ Carl Gustav Jung

«Extremer Reichtum ist eine Gefahr für die Demokratie», sagen über die Hälfte der knapp 3000 befragten Millionäre aus G20-Staaten laut einer Umfrage der «Patriotic Millionaires». Ferner stellte dieser Zusammenschluss wohlhabender US-Amerikaner fest, dass 63 Prozent jener Millionäre den Einfluss von Superreichen auf US-Präsident Trump als Bedrohung für die globale Stabilität ansehen.

Diese Besorgnis haben 370 Millionäre und Milliardäre am Dienstag auch den in Davos beim WEF konzentrierten Privilegierten aus aller Welt übermittelt. In einem offenen Brief forderten sie die «gewählten Führer» auf, die Superreichen – also sie selbst – zu besteuern, um «die zersetzenden Auswirkungen des extremen Reichtums auf unsere Demokratien und die Gesellschaft zu bekämpfen». Zum Beispiel kontrolliere eine handvoll extrem reicher Menschen die Medien, beeinflusse die Rechtssysteme in unzulässiger Weise und verwandele Recht in Unrecht.

Schon 2019 beanstandete der bekannte Historiker und Schriftsteller Ruthger Bregman an einer WEF-Podiumsdiskussion die Steuervermeidung der Superreichen. Die elitäre Veranstaltung bezeichnete er als «Feuerwehr-Konferenz, bei der man nicht über Löschwasser sprechen darf.» Daraufhin erhielt Bregman keine Einladungen nach Davos mehr. Auf seine Aussagen machte der Schweizer Aktivist Alec Gagneux aufmerksam, der sich seit Jahrzehnten kritisch mit dem WEF befasst. Ihm wurde kürzlich der Zutritt zu einem dreiteiligen Kurs über das WEF an der Volkshochschule Region Brugg verwehrt.

Nun ist die Erkenntnis, dass mit Geld politischer Einfluss einhergeht, alles andere als neu. Und extremer Reichtum macht die Sache nicht wirklich besser. Trotzdem hat man über Initiativen wie Patriotic Millionaires oder Taxmenow bisher eher selten etwas gehört, obwohl es sie schon lange gibt. Auch scheint es kein Problem, wenn ein Herr Gates fast im Alleingang versucht, globale Gesundheits-, Klima-, Ernährungs- oder Bevölkerungspolitik zu betreiben – im Gegenteil. Im Jahr, als der Milliardär Donald Trump zum zweiten Mal ins Weiße Haus einzieht, ist das Echo in den Gesinnungsmedien dagegen enorm – und uniform, wer hätte das gedacht.

Der neue US-Präsident hat jedoch «Davos geerdet», wie Achgut es nannte. In seiner kurzen Rede beim Weltwirtschaftsforum verteidigte er seine Politik und stellte klar, er habe schlicht eine «Revolution des gesunden Menschenverstands» begonnen. Mit deutlichen Worten sprach er unter anderem von ersten Maßnahmen gegen den «Green New Scam», und von einem «Erlass, der jegliche staatliche Zensur beendet»:

«Unsere Regierung wird die Äußerungen unserer eigenen Bürger nicht mehr als Fehlinformation oder Desinformation bezeichnen, was die Lieblingswörter von Zensoren und derer sind, die den freien Austausch von Ideen und, offen gesagt, den Fortschritt verhindern wollen.»

Wie der «Trumpismus» letztlich einzuordnen ist, muss jeder für sich selbst entscheiden. Skepsis ist definitiv angebracht, denn «einer von uns» sind weder der Präsident noch seine auserwählten Teammitglieder. Ob sie irgendeinen Sumpf trockenlegen oder Staatsverbrechen aufdecken werden oder was aus WHO- und Klimaverträgen wird, bleibt abzuwarten.

Das WHO-Dekret fordert jedenfalls die Übertragung der Gelder auf «glaubwürdige Partner», die die Aktivitäten übernehmen könnten. Zufällig scheint mit «Impfguru» Bill Gates ein weiterer Harris-Unterstützer kürzlich das Lager gewechselt zu haben: Nach einem gemeinsamen Abendessen zeigte er sich «beeindruckt» von Trumps Interesse an der globalen Gesundheit.

Mit dem Projekt «Stargate» sind weitere dunkle Wolken am Erwartungshorizont der Fangemeinde aufgezogen. Trump hat dieses Joint Venture zwischen den Konzernen OpenAI, Oracle, und SoftBank als das «größte KI-Infrastrukturprojekt der Geschichte» angekündigt. Der Stein des Anstoßes: Oracle-CEO Larry Ellison, der auch Fan von KI-gestützter Echtzeit-Überwachung ist, sieht einen weiteren potenziellen Einsatz der künstlichen Intelligenz. Sie könne dazu dienen, Krebserkrankungen zu erkennen und individuelle mRNA-«Impfstoffe» zur Behandlung innerhalb von 48 Stunden zu entwickeln.

Warum bitte sollten sich diese superreichen «Eliten» ins eigene Fleisch schneiden und direkt entgegen ihren eigenen Interessen handeln? Weil sie Menschenfreunde, sogenannte Philanthropen sind? Oder vielleicht, weil sie ein schlechtes Gewissen haben und ihre Schuld kompensieren müssen? Deswegen jedenfalls brauchen «Linke» laut Robert Willacker, einem deutschen Politikberater mit brasilianischen Wurzeln, rechte Parteien – ein ebenso überraschender wie humorvoller Erklärungsansatz.

Wenn eine Krähe der anderen kein Auge aushackt, dann tut sie das sich selbst noch weniger an. Dass Millionäre ernsthaft ihre eigene Besteuerung fordern oder Machteliten ihren eigenen Einfluss zugunsten anderer einschränken würden, halte ich für sehr unwahrscheinlich. So etwas glaube ich erst, wenn zum Beispiel die Rüstungsindustrie sich um Friedensverhandlungen bemüht, die Pharmalobby sich gegen institutionalisierte Korruption einsetzt, Zentralbanken ihre CBDC-Pläne für Bitcoin opfern oder der ÖRR die Abschaffung der Rundfunkgebühren fordert.

Estamos numa época tão estranha da humanidade…

Onde alguns querem reescrever a história, em vez de aprender e evoluir com a mesma. São com os erros que se cresce.

Onde o termo fascista é sinónimo de alguém com uma opinião diferente da sua, sem minimamente saber o real significado dessa palavra.

Onde defendem uma liberdade, que proíba o contraditório.

Onde não se discutem ideias, mas sim combatem ideias.

Onde o ambientalmente sustentável é substituir árvores e zonas verdes por estruturas em aço e zonas negras.

Onde os políticos constroem casas ou cidades, literalmente, em cima dos rios mas depois a culpa das cheias é as alterações climáticas.

Onde os alimentos tem menos importância que um peido de uma vaca.

Onde pessoas defendem que a solução para o aquecimento, é morrer de frio.

Onde a igualdade é favorecer um grupo, em detrimento de outro.

Onde o essencial é viver para consumir, em vez de usufruir.

Onde o importante é ser rico e ostentar essa mesma riqueza, mesmo que tenha de espezinhar outros para a conquistar.

Onde o mais importante é parecer em vez de ser.

Onde políticos defendem que o conhecimento pode levar a escolhas erradas, defendem o carneirismo.

Onde um político define o que é verdade ou mentira, limitando o que as pessoas podem expressar. Mas quem controla o controlador.

Onde os revisores da verdade deixaram de estar num gabinete, passando a ser um exército de jovens atrás de um teclado.

Onde, são propostas e aprovadas limitações de liberdade, sem esclarecimento ou divulgação pública. Pior que a obscuridade, é desinteresse da comunidade por liberdade.

Onde a censura é o novo normal, defender o contrário é que é censurável.

Onde a imprensa é tão livre como uma pomba dentro de sua gaiola.

Onde, quem comete o crime é protegido, quem o denúncia é perseguido.

Onde o certo é pensar com a cabeça dos outros, sem questionar.

Onde os pais delegaram o papel de educar às escolas e aos ecrãs azuis.

Onde a escola deixou de ser um lugar de conhecimento e/ou do desenvolvimento do espírito crítico.

Onde as crianças crescem doutrinados por políticos e por AI.

Onde a sociedade é programada e com um destino predefinido, como um rato dentro da sua roda.

Onde o maior erro, é pretender construir seres que não cometem erros, que não tenham vícios. Quando isso acontecer, deixamos de ser humanos. A imperfeição é a essência dos seres humanos, é o que nos difere das máquinas.

Onde só se ensina a não cair, em vez de ajudar e incentivar a levantar.

Onde se suspende a liberdade de circulação e os direitos mais básicos, sem ninguém questionar.

Onde a privacidade é crime.

Onde Satoshi é excomungado, mas Miguel Tiago é idoleterado.

Onde a moeda é utilizado como uma arma.

Onde uma guerra é digladiada entre zeros e uns, sem o comum mortal aperceber da sua existência.

Onde crianças caem em campos de batalha, como folhas em pleno outono.

Onde o direito ao Livre-arbítrio está sob ameaça.

Der gut informierte Bürger denkt bei der Pandemie sofort an Intensivstationen, an die Bilder aus Bergamo und erinnert sich an die Berichterstattung damals – also muss es wohl ein Maximum gewesen sein. Manche Skeptiker behaupten jedoch das Gegenteil. Klarheit sollte ein Blick nach Wiesbaden, zum Statistischen Bundesamt, schaffen. Schließlich sitzen dort gut bezahlte Profis, die seit vielen Jahrzehnten die Sterbestatistik pflegen und veröffentlichen. Jeder Todesfall wird in Deutschland über die Standesämter exakt erfasst.

Doch die Überraschung: Das Statistische Bundesamt liefert uns auf diese einfache Frage zwei extrem unterschiedliche Antworten – ein Minimum und ein Maximum. Das Ergebnis hängt davon ab, wie tief man in die Veröffentlichungen des Bundesamtes eintaucht. Betrachtet man nur die Webseiten und Pressemitteilungen, erhält man den Eindruck eines Maximums. Schaut man jedoch etwas tiefer in die Tabellen und Rohdaten, zeigt sich plötzlich ein Minimum. Aber wie kann das sein? Beides gleichzeitig geht ja wohl kaum. Wer lügt hier – die Tabellen des Amtes oder die Pressemitteilungen? Gehen wir dieser Frage Schritt für Schritt auf den Grund.

2020: Ein historisches Maximum?

Schauen wir uns die vielen Hundert Veröffentlichungen des Statistischen Bundesamtes aus dieser Zeit an. Oder wir kürzen ab und fragen ChatGPT, da die KI auf diesen Daten trainiert wurde und das gesamte Material kennt. Die Frage an ChatGPT lautet also: Wie war das Sterbegeschehen im Jahr 2020 im Vergleich zu den Vorjahren?

ChatGPT antwortet: »Im Jahr 2020 war die Sterblichkeit in Deutschland höher als in den Jahren zuvor. Es gab eine Übersterblichkeit von etwa 982.000 Todesfällen, das sind rund 46.000 mehr als der Durchschnitt der Vorjahre (2016 bis 2019). Dieser Anstieg wurde überwiegend im Zusammenhang mit der COVID-19-Pandemie gesehen. Während die Sterbezahlen in den Vorjahren schwankten, war ein solch signifikanter Anstieg wie 2020 bisher nicht zu beobachten.«

Wir fragen konkreter: Ist es ein Fakt, dass wir eine so ernste Lage im Sterbegeschehen wie im Frühjahr 2020 noch nie erlebt haben?

ChatGPT bestätigt: »Ja, die COVID-19-Pandemie führte im Frühjahr 2020 zu einer außergewöhnlichen Situation im Sterbegeschehen in Deutschland. Die dramatische Übersterblichkeit, die ab der 13. Kalenderwoche auftrat, veranlasste das Statistische Bundesamt, besonders eindringliche Warnungen zu veröffentlichen. Der damalige Vizepräsident des Amtes und andere führende Stimmen wiesen öffentlich darauf hin, dass die Todesfallzahlen stark vom Durchschnitt abwichen. Diese klare Warnung richtete sich an die Öffentlichkeit und die Politik gleichermaßen. Die Medien berichteten intensiv über diese Warnungen, was das Bewusstsein für die Schwere der Pandemie erheblich schärfte. In den vergangenen Jahrzehnten hatte es keine vergleichbare Übersterblichkeit gegeben, die eine solch umfangreiche Kommunikation durch das Statistische Bundesamt erforderlich gemacht hätte.«

Ein gut informierter Zeitungsleser wird sich an dieser Stelle bestätigt fühlen: Ja, so war es damals. Ein Maximum im Sterbegeschehen – wegen der Pandemie. Oder etwa nicht?

2020: Ein historisches Minimum?

Tauchen wir in die Rohdaten des Statistischen Bundesamtes ein. Die Tabellen, die das Amt seit Jahrzehnten verlässlich veröffentlicht, nennen sich Sterbetafeln. Diese werden jährlich bereitgestellt und stehen auf der Website des Bundesamtes zum Download bereit. Ein erster Blick in die Sterbetafeln mag den Laien abschrecken, doch mit einer kurzen Erklärung wird alles verständlich. Wir gehen schrittweise vor.

Nehmen wir die Sterbetafel des Jahres 2017. Sie enthält zwei große Tabellen – eine für Männer und eine für Frauen. Jede Zeile der Tabelle steht für einen Jahrgang, zum Beispiel zeigt die Zeile 79 die Daten der 79-jährigen Männer. Besonders wichtig ist nun die zweite Spalte, in der der Wert 0,05 eingetragen ist. Das bedeutet, dass 5 Prozent der 79-jährigen Männer im Jahr 2017 verstorben sind. Das ist die wichtige Kennzahl. Wenn wir diesen exakten Wert, den man auch als Sterberate bezeichnet, nun in ein Säulendiagramm eintragen, erhalten wir eine leicht verständliche visuelle Darstellung (Grafik 1).

Es ist wichtig zu betonen, dass dieser Wert weder ein Schätzwert noch eine Modellrechnung oder Prognose ist, sondern ein exakter Messwert, basierend auf einer zuverlässigen Zählung. Sterberaten (für die Fachleute auch Sterbewahrscheinlichkeiten qx) sind seit Johann Peter Süßmilch (1707–1767) der Goldstandard der Sterbestatistik. Jeder Aktuar wird das bestätigen. Fügen wir nun die Sterberaten der 79-jährigen Männer aus den Jahren davor und danach hinzu, um das Gesamtbild zu sehen (Grafik 2). Und nun die entscheidende Frage: Zeigt das Jahr 2020 ein Maximum oder ein Minimum?

Ein kritischer Leser könnte vermuten, dass die 79-jährigen Männer eine Ausnahme darstellen und andere Jahrgänge im Jahr 2020 ein Maximum zeigen würden. Doch das trifft nicht zu. Kein einziger Jahrgang verzeichnete im Jahr 2020 ein Maximum. Im Gegenteil: Auch die 1-Jährigen, 2-Jährigen, 3-Jährigen, 9-Jährigen, 10-Jährigen, 15-Jährigen, 18-Jährigen und viele weitere männliche Jahrgänge hatten ihr Minimum im Jahr 2020. Dasselbe gilt bei den Frauen. Insgesamt hatten 31 Jahrgänge ihr Minimum im Jahr 2020. Wenn wir schließlich alle Jahrgänge in einer einzigen Grafik zusammenfassen, ergibt sich ein klares Bild: Das Minimum im Sterbegeschehen lag im Jahr 2020 (Grafik 3).

Ein kritischer Leser könnte nun wiederum vermuten, dass es innerhalb des Jahres 2020 möglicherweise starke Ausschläge nach oben bei einzelnen Jahrgängen gegeben haben könnte, die später durch Ausschläge nach unten ausgeglichen wurden – und dass diese Schwankungen in der jährlichen Übersicht nicht sichtbar sind. Doch auch das trifft nicht zu. Ein Blick auf die wöchentlichen Sterberaten zeigt, dass die ersten acht Monate der Pandemie keine nennenswerten Auffälligkeiten aufweisen. Es bleibt dabei: Die Rohdaten des Statistischen Bundesamtes bestätigen zweifelsfrei, dass die ersten acht Monate der Pandemie das historische Minimum im Sterbegeschehen darstellen. (Für die Fachleute sei angemerkt, dass im gleichen Zeitraum die Lebenserwartung die historischen Höchststände erreicht hatte – Grafik 4.)

So konstruierte das Amt aus einem Minimum ein Maximum:

Zur Erinnerung: Die Rohdaten des Statistischen Bundesamtes, die in den jährlichen Sterbetafeln zweifelsfrei dokumentiert sind, zeigen für das Jahr 2020 eindeutig ein Minimum im Sterbegeschehen. Aus diesen »in Stein gemeißelten« Zahlen ein Maximum zu »konstruieren«, ohne die Rohdaten selbst zu verändern, scheint auf den ersten Blick eine unlösbare Aufgabe. Jeder Student würde an einer solchen Herausforderung scheitern. Doch das Statistische Bundesamt hat einen kreativen Weg gefunden - ein Meisterstück gezielter Manipulation. In fünf Schritten zeigt sich, wie diese Täuschung der Öffentlichkeit umgesetzt wurde:

(1) Ignorieren der Sterberaten: Die präzisen, objektiven und leicht verständlichen Sterberaten aus den eigenen Sterbetafeln wurden konsequent ignoriert und verschwiegen. Diese Daten widersprachen dem gewünschten Narrativ und wurden daher gezielt ausgeklammert.

(2) Fokus auf absolute Todeszahlen: Die Aufmerksamkeit wurde stattdessen auf die absolute Zahl der Todesfälle gelenkt. Diese wirkt allein durch ihre schiere Größe dramatisch und emotionalisiert die Diskussion. Ein entscheidender Faktor wurde dabei ignoriert: Die absolute Zahl der Todesfälle steigt aufgrund der demografischen Entwicklung jedes Jahr an. Viele Menschen verstehen diesen Zusammenhang nicht und verbinden die steigenden Zahlen fälschlicherweise mit der vermeintlichen Pandemie.

(3) Einführung der Übersterblichkeit als neue Kennzahl: Erst ab Beginn der „Pandemie“ wurde die Kennzahl "Übersterblichkeit" eingeführt – und dies mit einer fragwürdigen Methode, die systematisch überhöhte Werte lieferte. Diese Kennzahl wurde regelmäßig, oft monatlich oder sogar wöchentlich, berechnet und diente als ständige Grundlage für alarmierende Schlagzeilen.

(4) Intensive Öffentlichkeitsarbeit: Durch eine breit angelegte Kampagne wurden die manipulativen Kennzahlen gezielt in den Fokus gerückt. Pressemitteilungen, Podcasts und öffentliche Auftritte konzentrierten sich fast ausschließlich auf die absoluten Todeszahlen und die Übersterblichkeit. Ziel war es, den Eindruck einer dramatischen Situation in der Öffentlichkeit zu verstärken.

(5) Bekämpfen kritischer Stimmen: Kritiker, die die Schwächen und manipulativen Aspekte dieser Methoden aufdeckten, wurden systematisch diskreditiert. Ihre Glaubwürdigkeit und Kompetenz wurden öffentlich infrage gestellt, um das sorgsam konstruierte Narrativ zu schützen.

Ohne diesen begleitenden Statistik-Betrug wäre das gesamte Pandemie-Theater meiner Meinung nach nicht möglich gewesen. Wer aus einem faktischen Minimum ein scheinbares Maximum "erschafft", handelt betrügerisch. Die Folgen dieses Betruges sind gravierend. Denken wir an die Angst, die in der Bevölkerung geschürt wurde – die Angst, bald sterben zu müssen. Denken wir an Masken, Abstandsregeln, isolierte ältere Menschen, Kinderimpfungen und all die Maßnahmen, die unter anderem auf diese falsche Statistik zurückgehen.

Wollen wir Bürger uns das gefallen lassen?

Wenn wir als Bürger zulassen, dass ein derart offensichtlicher und nachprüfbarer Täuschungsversuch ohne Konsequenzen bleibt, dann gefährdet das nicht nur die Integrität unserer Institutionen – es untergräbt das Fundament unserer Gesellschaft. In der DDR feierte man öffentlich Planerfüllung und Übererfüllung, während die Regale leer blieben. Damals wusste jeder: Statistik war ein Propagandainstrument. Niemand traute den Zahlen, die das Staatsfernsehen verkündete.

Während der Pandemie war es anders. Die Menschen vertrauten den Mitteilungen des Statistischen Bundesamtes und des RKI – blind. Die Enthüllungen durch den "RKI-Leak" haben gezeigt, dass auch das Robert-Koch-Institut nicht der Wissenschaft, sondern den Weisungen des Gesundheitsministers und militärischen Vorgaben folgte. Warum sollte es beim Statistischen Bundesamt anders gewesen sein? Diese Behörde ist dem Innenministerium unterstellt und somit ebenfalls weisungsgebunden.

Die Beweise für Täuschung liegen offen zutage. Es braucht keinen Whistleblower, keine geheimen Enthüllungen: Die Rohdaten des Statistischen Bundesamtes sprechen für sich. Sie sind öffentlich einsehbar – klar und unmissverständlich. Die Daten, die Tabellen, die Veröffentlichungen des Amtes selbst – sie sind die Anklageschrift. Sie zeigen, was wirklich war. Nicht mehr und nicht weniger.

Und wir? Was tun wir? Schweigen wir? Oder fordern wir endlich ein, was unser Recht ist? Wir Bürger dürfen das nicht hinnehmen. Es ist Zeit, unsere Behörden zur Rechenschaft zu ziehen. Diese Institutionen arbeiten nicht für sich – sie arbeiten für uns. Wir finanzieren sie, und wir haben das Recht, Transparenz und Verantwortung einzufordern. Manipulationen wie diese müssen aufgearbeitet werden und dürfen nie wieder geschehen. Die Strukturen, die solche Fehlentwicklungen in unseren Behörden ermöglicht haben, müssen offengelegt werden. Denn eine Demokratie lebt von Vertrauen – und Vertrauen muss verdient werden. Jeden Tag aufs Neue.

Since its creation in 2009, Bitcoin has symbolized innovation and resilience. However, from time to time, alarmist narratives arise about emerging technologies that could "break" its security. Among these, quantum computing stands out as one of the most recurrent. But does quantum computing truly threaten Bitcoin? And more importantly, what is the community doing to ensure the protocol remains invulnerable?

The answer, contrary to sensationalist headlines, is reassuring: Bitcoin is secure, and the community is already preparing for a future where quantum computing becomes a practical reality. Let’s dive into this topic to understand why the concerns are exaggerated and how the development of BIP-360 demonstrates that Bitcoin is one step ahead.

What Is Quantum Computing, and Why Is Bitcoin Not Threatened?

Quantum computing leverages principles of quantum mechanics to perform calculations that, in theory, could exponentially surpass classical computers—and it has nothing to do with what so-called “quantum coaches” teach to scam the uninformed. One of the concerns is that this technology could compromise two key aspects of Bitcoin’s security:
1. Wallets: These use elliptic curve algorithms (ECDSA) to protect private keys. A sufficiently powerful quantum computer could deduce a private key from its public key.
2. Mining: This is based on the SHA-256 algorithm, which secures the consensus process. A quantum attack could, in theory, compromise the proof-of-work mechanism.
Understanding Quantum Computing’s Attack Priorities

While quantum computing is often presented as a threat to Bitcoin, not all parts of the network are equally vulnerable. Theoretical attacks would be prioritized based on two main factors: ease of execution and potential reward. This creates two categories of attacks:

1. Attacks on Wallets

Bitcoin wallets, secured by elliptic curve algorithms, would be the initial targets due to the relative vulnerability of their public keys, especially those already exposed on the blockchain. Two attack scenarios stand out:
- Short-term attacks: These occur during the interval between sending a transaction and its inclusion in a block (approximately 10 minutes). A quantum computer could intercept the exposed public key and derive the corresponding private key to redirect funds by creating a transaction with higher fees.
- Long-term attacks: These focus on old wallets whose public keys are permanently exposed. Wallets associated with Satoshi Nakamoto, for example, are especially vulnerable because they were created before the practice of using hashes to mask public keys.
We can infer a priority order for how such attacks might occur based on urgency and importance.

Bitcoin Quantum Attack: Prioritization Matrix (Urgency vs. Importance)

2. Attacks on Mining

Targeting the SHA-256 algorithm, which secures the mining process, would be the next objective. However, this is far more complex and requires a level of quantum computational power that is currently non-existent and far from realization. A successful attack would allow for the recalculation of all possible hashes to dominate the consensus process and potentially "mine" it instantly.

Satoshi Nakamoto in 2010 on Quantum Computing and Bitcoin Attacks

Recently, Narcelio asked me about a statement I made on Tubacast:

https://x.com/eddieoz/status/1868371296683511969

If an attack became a reality before Bitcoin was prepared, it would be necessary to define the last block prior to the attack and proceed from there using a new hashing algorithm. The solution would resemble the response to the infamous 2013 bug. It’s a fact that this would cause market panic, and Bitcoin's price would drop significantly, creating a potential opportunity for the well-informed.

Preferably, if developers could anticipate the threat and had time to work on a solution and build consensus before an attack, they would simply decide on a future block for the fork, which would then adopt the new algorithm. It might even rehash previous blocks (reaching consensus on them) to avoid potential reorganization through the re-mining of blocks using the old hash. (I often use the term "shielding" old transactions).

How Can Users Protect Themselves?

While quantum computing is still far from being a practical threat, some simple measures can already protect users against hypothetical scenarios:
- Avoid using exposed public keys: Ensure funds sent to old wallets are transferred to new ones that use public key hashes. This reduces the risk of long-term attacks.
- Use modern wallets: Opt for wallets compatible with SegWit or Taproot, which implement better security practices.
- Monitor security updates: Stay informed about updates from the Bitcoin community, such as the implementation of BIP-360, which will introduce quantum-resistant addresses.
- Do not reuse addresses: Every transaction should be associated with a new address to minimize the risk of repeated exposure of the same public key.
- Adopt secure backup practices: Create offline backups of private keys and seeds in secure locations, protected from unauthorized access.
BIP-360 and Bitcoin’s Preparation for the Future

Even though quantum computing is still beyond practical reach, the Bitcoin community is not standing still. A concrete example is BIP-360, a proposal that establishes the technical framework to make wallets resistant to quantum attacks.

BIP-360 addresses three main pillars:
1. Introduction of quantum-resistant addresses: A new address format starting with "BC1R" will be used. These addresses will be compatible with post-quantum algorithms, ensuring that stored funds are protected from future attacks.
2. Compatibility with the current ecosystem: The proposal allows users to transfer funds from old addresses to new ones without requiring drastic changes to the network infrastructure.
3. Flexibility for future updates: BIP-360 does not limit the choice of specific algorithms. Instead, it serves as a foundation for implementing new post-quantum algorithms as technology evolves.
This proposal demonstrates how Bitcoin can adapt to emerging threats without compromising its decentralized structure.

Post-Quantum Algorithms: The Future of Bitcoin Cryptography

The community is exploring various algorithms to protect Bitcoin from quantum attacks. Among the most discussed are:
- Falcon: A solution combining smaller public keys with compact digital signatures. Although it has been tested in limited scenarios, it still faces scalability and performance challenges.
- Sphincs: Hash-based, this algorithm is renowned for its resilience, but its signatures can be extremely large, making it less efficient for networks like Bitcoin’s blockchain.
- Lamport: Created in 1977, it’s considered one of the earliest post-quantum security solutions. Despite its reliability, its gigantic public keys (16,000 bytes) make it impractical and costly for Bitcoin.
Two technologies show great promise and are well-regarded by the community:
1. Lattice-Based Cryptography: Considered one of the most promising, it uses complex mathematical structures to create systems nearly immune to quantum computing. Its implementation is still in its early stages, but the community is optimistic.
2. Supersingular Elliptic Curve Isogeny: These are very recent digital signature algorithms and require extensive study and testing before being ready for practical market use.
The final choice of algorithm will depend on factors such as efficiency, cost, and integration capability with the current system. Additionally, it is preferable that these algorithms are standardized before implementation, a process that may take up to 10 years.

Why Quantum Computing Is Far from Being a Threat

The alarmist narrative about quantum computing overlooks the technical and practical challenges that still need to be overcome. Among them:
- Insufficient number of qubits: Current quantum computers have only a few hundred qubits, whereas successful attacks would require millions.
- High error rate: Quantum stability remains a barrier to reliable large-scale operations.
- High costs: Building and operating large-scale quantum computers requires massive investments, limiting their use to scientific or specific applications.
Moreover, even if quantum computers make significant advancements, Bitcoin is already adapting to ensure its infrastructure is prepared to respond.

Conclusion: Bitcoin’s Secure Future

Despite advancements in quantum computing, the reality is that Bitcoin is far from being threatened. Its security is ensured not only by its robust architecture but also by the community’s constant efforts to anticipate and mitigate challenges.

The implementation of BIP-360 and the pursuit of post-quantum algorithms demonstrate that Bitcoin is not only resilient but also proactive. By adopting practical measures, such as using modern wallets and migrating to quantum-resistant addresses, users can further protect themselves against potential threats.

Bitcoin’s future is not at risk—it is being carefully shaped to withstand any emerging technology, including quantum computing.

My own stats on what I’ve done over the weekend:
- Spoke to +100 developers, it was great seeing a couple of familiar Flemish faces and meeting some new ones but overall the crowd was extremely diverse.
- Ended up doing a short interview promoting the protocol and ended up going to 0 talks.
- Tried to evangelize by going booth by booth to distribute a Nostr flyer to other FOSDEM projects, with the hope that they would broadcast the info towards their SOME person to add Nostr on their list or to build out a library for the languages that were present ( This was a fairly slow approach )
- Kept it to Nostr protocol 95% of the time, the Bitcoin narrative is not always a good time to push and as a side note I’ve met more Monero users than in the last 5 years.
- Was able to convince some engineers to look into the #soveng endeavor.
Small overview from the most common questions:
- They have heard about Nostr but are not sure of the details. ( mostly through the bitcoin community )
- What is the difference with ActivityPub, Mastodon, Fediverse ?
- IOT developers, so questions regarding MQTT & Meshtastic integrations ?
- Current state of MLS on Nostr ?
- What are the current biggest clients / apps build on Nostr ?
- Will jack still give a talk ?
Things we could improve:
- Bring more stickers like loads more,
- Bring T-shirts, Pins… could be a good way to fund these adventures instead of raising funds. ( Most projects where selling something to help raise funds for projects )
- Almost no onboarding / client installs.
- Compared to the Nostr booth at BTC Amsterdam not a single person asked if they could charge their phone.
Personal Note: The last time I visited was roughly 13 years ago and me being a little more seasoned I just loved the fact that I was able to pay some support to the open source projects I’ve been using for years ( homebrew, modzilla, Free BSD,.. ) and see the amazing diverse crowd that is the open source Movement 🧡

Al final shoutout to our great pirate crew 🏴‍☠️: The Dutch Guard ( nostr:npub1qe3e5wrvnsgpggtkytxteaqfprz0rgxr8c3l34kk3a9t7e2l3acslezefe & nostr:npub1l77twp5l02jadkcjn6eeulv2j7y5vmf9tf3hhtq7h7rp0vzhgpzqz0swft ) and a adrenaline fueled nostr:npub1t6jxfqz9hv0lygn9thwndekuahwyxkgvycyscjrtauuw73gd5k7sqvksrw , nostr:npub1rfw075gc6pc693w5v568xw4mnu7umlzpkfxmqye0cgxm7qw8tauqfck3t8 and nostr:npub1r30l8j4vmppvq8w23umcyvd3vct4zmfpfkn4c7h2h057rmlfcrmq9xt9ma amazing finally meeting you IRL after close to 2 years since the Yakihonne hackathon 😀

Die grauenvollste Aussicht ist die der Technokratie – \ einer kontrollierenden Herrschaft, \ die durch verstümmelte und verstümmelnde Geister ausgeübt wird. \ Ernst Jünger

«Davos ist nicht mehr sexy», das Weltwirtschaftsforum (WEF) mache Davos kaputt, diese Aussagen eines Einheimischen las ich kürzlich in der Handelszeitung. Während sich einige vor Ort enorm an der «teuersten Gewerbeausstellung der Welt» bereicherten, würden die negativen Begleiterscheinungen wie Wohnungsnot und Niedergang der lokalen Wirtschaft immer deutlicher.

Nächsten Montag beginnt in dem Schweizer Bergdorf erneut ein Jahrestreffen dieses elitären Clubs der Konzerne, bei dem man mit hochrangigen Politikern aus aller Welt und ausgewählten Vertretern der Systemmedien zusammenhocken wird. Wie bereits in den vergangenen vier Jahren wird die Präsidentin der EU-Kommission, Ursula von der Leyen, in Begleitung von Klaus Schwab ihre Grundsatzansprache halten.

Der deutsche WEF-Gründer hatte bei dieser Gelegenheit immer höchst lobende Worte für seine Landsmännin: 2021 erklärte er sich «stolz, dass Europa wieder unter Ihrer Führung steht» und 2022 fand er es bemerkenswert, was sie erreicht habe angesichts des «erstaunlichen Wandels», den die Welt in den vorangegangenen zwei Jahren erlebt habe; es gebe nun einen «neuen europäischen Geist».

Von der Leyens Handeln während der sogenannten Corona-«Pandemie» lobte Schwab damals bereits ebenso, wie es diese Woche das Karlspreis-Direktorium tat, als man der Beschuldigten im Fall Pfizergate die diesjährige internationale Auszeichnung «für Verdienste um die europäische Einigung» verlieh. Außerdem habe sie die EU nicht nur gegen den «Aggressor Russland», sondern auch gegen die «innere Bedrohung durch Rassisten und Demagogen» sowie gegen den Klimawandel verteidigt.

Jene Herausforderungen durch «Krisen epochalen Ausmaßes» werden indes aus dem Umfeld des WEF nicht nur herbeigeredet – wie man alljährlich zur Zeit des Davoser Treffens im Global Risks Report nachlesen kann, der zusammen mit dem Versicherungskonzern Zurich erstellt wird. Seit die Globalisten 2020/21 in der Praxis gesehen haben, wie gut eine konzertierte und konsequente Angst-Kampagne funktionieren kann, geht es Schlag auf Schlag. Sie setzen alles daran, Schwabs goldenes Zeitfenster des «Great Reset» zu nutzen.

Ziel dieses «großen Umbruchs» ist die totale Kontrolle der Technokraten über die Menschen unter dem Deckmantel einer globalen Gesundheitsfürsorge. Wie aber könnte man so etwas erreichen? Ein Mittel dazu ist die «kreative Zerstörung». Weitere unabdingbare Werkzeug sind die Einbindung, ja Gleichschaltung der Medien und der Justiz.

Ein «Great Mental Reset» sei die Voraussetzung dafür, dass ein Großteil der Menschen Einschränkungen und Manipulationen wie durch die Corona-Maßnahmen praktisch kritik- und widerstandslos hinnehme, sagt der Mediziner und Molekulargenetiker Michael Nehls. Er meint damit eine regelrechte Umprogrammierung des Gehirns, wodurch nach und nach unsere Individualität und unser soziales Bewusstsein eliminiert und durch unreflektierten Konformismus ersetzt werden.

Der aktuelle Zustand unserer Gesellschaften ist auch für den Schweizer Rechtsanwalt Philipp Kruse alarmierend. Durch den Umgang mit der «Pandemie» sieht er die Grundlagen von Recht und Vernunft erschüttert, die Rechtsstaatlichkeit stehe auf dem Prüfstand. Seiner dringenden Mahnung an alle Bürger, die Prinzipien von Recht und Freiheit zu verteidigen, kann ich mich nur anschließen.

Ich begann, Social Media aufzubauen, \ um den Menschen eine Stimme zu geben. \ Mark Zuckerberg

Sind euch auch die Tränen gekommen, als ihr Mark Zuckerbergs Wendehals-Deklaration bezüglich der Meinungsfreiheit auf seinen Portalen gehört habt? Rührend, oder? Während er früher die offensichtliche Zensur leugnete und später die Regierung Biden dafür verantwortlich machte, will er nun angeblich «die Zensur auf unseren Plattformen drastisch reduzieren».

«Purer Opportunismus» ob des anstehenden Regierungswechsels wäre als Klassifizierung viel zu kurz gegriffen. Der jetzige Schachzug des Meta-Chefs ist genauso Teil einer kühl kalkulierten Business-Strategie, wie es die 180 Grad umgekehrte Praxis vorher war. Social Media sind ein höchst lukratives Geschäft. Hinzu kommt vielleicht noch ein bisschen verkorkstes Ego, weil derartig viel Einfluss und Geld sicher auch auf die Psyche schlagen. Verständlich.

«Es ist an der Zeit, zu unseren Wurzeln der freien Meinungsäußerung auf Facebook und Instagram zurückzukehren. Ich begann, Social Media aufzubauen, um den Menschen eine Stimme zu geben», sagte Zuckerberg.

Welche Wurzeln? Hat der Mann vergessen, dass er von der Überwachung, dem Ausspionieren und dem Ausverkauf sämtlicher Daten und digitaler Spuren sowie der Manipulation seiner «Kunden» lebt? Das ist knallharter Kommerz, nichts anderes. Um freie Meinungsäußerung geht es bei diesem Geschäft ganz sicher nicht, und das war auch noch nie so. Die Wurzeln von Facebook liegen in einem Projekt des US-Militärs mit dem Namen «LifeLog». Dessen Ziel war es, «ein digitales Protokoll vom Leben eines Menschen zu erstellen».

Der Richtungswechsel kommt allerdings nicht überraschend. Schon Anfang Dezember hatte Meta-Präsident Nick Clegg von «zu hoher Fehlerquote bei der Moderation» von Inhalten gesprochen. Bei der Gelegenheit erwähnte er auch, dass Mark sehr daran interessiert sei, eine aktive Rolle in den Debatten über eine amerikanische Führungsrolle im technologischen Bereich zu spielen.

Während Milliardärskollege und Big Tech-Konkurrent Elon Musk bereits seinen Posten in der kommenden Trump-Regierung in Aussicht hat, möchte Zuckerberg also nicht nur seine Haut retten – Trump hatte ihn einmal einen «Feind des Volkes» genannt und ihm lebenslange Haft angedroht –, sondern am liebsten auch mitspielen. KI-Berater ist wohl die gewünschte Funktion, wie man nach einem Treffen Trump-Zuckerberg hörte. An seine Verhaftung dachte vermutlich auch ein weiterer Multimilliardär mit eigener Social Media-Plattform, Pavel Durov, als er Zuckerberg jetzt kritisierte und gleichzeitig warnte.

Politik und Systemmedien drehen jedenfalls durch – was zu viel ist, ist zu viel. Etwas weniger Zensur und mehr Meinungsfreiheit würden die Freiheit der Bürger schwächen und seien potenziell vernichtend für die Menschenrechte. Zuckerberg setze mit dem neuen Kurs die Demokratie aufs Spiel, das sei eine «Einladung zum nächsten Völkermord», ernsthaft. Die Frage sei, ob sich die EU gegen Musk und Zuckerberg behaupten könne, Brüssel müsse jedenfalls hart durchgreifen.

Auch um die Faktenchecker macht man sich Sorgen. Für die deutsche Nachrichtenagentur dpa und die «Experten» von Correctiv, die (noch) Partner für Fact-Checking-Aktivitäten von Facebook sind, sei das ein «lukratives Geschäftsmodell». Aber möglicherweise werden die Inhalte ohne diese vermeintlichen Korrektoren ja sogar besser. Anders als Meta wollen jedoch Scholz, Faeser und die Tagesschau keine Fehler zugeben und zum Beispiel Correctiv-Falschaussagen einräumen.

Bei derlei dramatischen Befürchtungen wundert es nicht, dass der öffentliche Plausch auf X zwischen Elon Musk und AfD-Chefin Alice Weidel von 150 EU-Beamten überwacht wurde, falls es irgendwelche Rechtsverstöße geben sollte, die man ihnen ankreiden könnte. Auch der Deutsche Bundestag war wachsam. Gefunden haben dürften sie nichts. Das Ganze war eher eine Show, viel Wind wurde gemacht, aber letztlich gab es nichts als heiße Luft.

Das Anbiedern bei Donald Trump ist indes gerade in Mode. Die Weltgesundheitsorganisation (WHO) tut das auch, denn sie fürchtet um Spenden von über einer Milliarde Dollar. Eventuell könnte ja Elon Musk auch hier künftig aushelfen und der Organisation sowie deren größtem privaten Förderer, Bill Gates, etwas unter die Arme greifen. Nachdem Musks KI-Projekt xAI kürzlich von BlackRock & Co. sechs Milliarden eingestrichen hat, geht da vielleicht etwas.

Um dos padrões mais bem estabelecidos ao medir a opinião pública é que cada geração tende a seguir um caminho semelhante em termos de política e ideologia geral. Seus membros compartilham das mesmas experiências formativas, atingem os marcos importantes da vida ao mesmo tempo e convivem nos mesmos espaços. Então, como devemos entender os relatórios que mostram que a Geração Z é hiperprogressista em certos assuntos, mas surpreendentemente conservadora em outros?

A resposta, nas palavras de Alice Evans, pesquisadora visitante na Universidade de Stanford e uma das principais estudiosas do tema, é que os jovens de hoje estão passando por um grande divergência de gênero, com as jovens mulheres do primeiro grupo e os jovens homens do segundo. A Geração Z representa duas gerações, e não apenas uma.

Em países de todos os continentes, surgiu um distanciamento ideológico entre jovens homens e mulheres. Milhões de pessoas que compartilham das mesmas cidades, locais de trabalho, salas de aula e até casas, não veem mais as coisas da mesma maneira.

Nos Estados Unidos, os dados da Gallup mostram que, após décadas em que os sexos estavam distribuídos de forma relativamente equilibrada entre visões políticas liberais e conservadoras, as mulheres entre 18 e 30 anos são agora 30 pontos percentuais mais liberais do que os homens dessa faixa etária. Essa diferença surgiu em apenas seis anos.

A Alemanha também apresenta um distanciamento de 30 pontos entre homens jovens conservadores e mulheres jovens progressistas, e no Reino Unido, a diferença é de 25 pontos. Na Polônia, no ano passado, quase metade dos homens entre 18 e 21 anos apoiou o partido de extrema direita Confederation, em contraste com apenas um sexto das jovens mulheres dessa mesma idade.

Fora do Ocidente, há divisões ainda mais acentuadas. Na Coreia do Sul, há um enorme abismo entre homens e mulheres jovens, e a situação é semelhante na China. Na África, a Tunísia apresenta o mesmo padrão. Vale notar que em todos os países essa divisão drástica ocorre principalmente entre a geração mais jovem, sendo muito menos pronunciada entre homens e mulheres na faixa dos 30 anos ou mais velhos.

O movimento # MeToo foi o principal estopim, trazendo à tona valores feministas intensos entre jovens mulheres que se sentiram empoderadas para denunciar injustiças de longa data. Esse estopim encontrou especialmente terreno fértil na Coreia do Sul, onde a desigualdade de gênero é bastante visível e a misoginia explícita é comum. (palavras da Financial Times, eu só traduzi)

Na eleição presidencial da Coreia do Sul em 2022, enquanto homens e mulheres mais velhos votaram de forma unificada, os jovens homens apoiaram fortemente o partido de direita People Power, enquanto as jovens mulheres apoiaram o partido liberal Democratic em números quase iguais e opostos.

A situação na Coreia é extrema, mas serve como um alerta para outros países sobre o que pode acontecer quando jovens homens e mulheres se distanciam. A sociedade está dividida, a taxa de casamento despencou e a taxa de natalidade caiu drasticamente, chegando a 0,78 filhos por mulher em 2022, o menor número no mundo todo.

Sete anos após a explosão inicial do movimento # MeToo, a divergência de gênero em atitudes tornou-se autossustentável.

Dados das pesquisas mostram que em muitos países, as diferenças ideológicas vão além dessa questão específica. A divisão progressista-conservadora sobre assédio sexual parece ter causado ou pelo menos faz parte de um alinhamento mais amplo, em que jovens homens e mulheres estão se organizando em grupos conservadores e liberais em outros assuntos.

Nos EUA, Reino Unido e Alemanha, as jovens mulheres agora adotam posturas mais liberais sobre temas como imigração e justiça racial, enquanto grupos etários mais velhos permanecem equilibrados. A tendência na maioria dos países tem sido de mulheres se inclinando mais para a esquerda, enquanto os homens permanecem estáveis. No entanto, há sinais de que os jovens homens estão se movendo para a direita na Alemanha, tornando-se mais críticos em relação à imigração e se aproximando do partido de extrema direita AfD nos últimos anos.

Seria fácil dizer que tudo isso é apenas uma fase passageira, mas os abismos ideológicos apenas crescem, e os dados mostram que as experiências políticas formativas das pessoas são difíceis de mudar. Tudo isso é agravado pelo fato de que o aumento dos smartphones e das redes sociais faz com que os jovens homens e mulheres agora vivam em espaços separados e tenham culturas distintas.

As opiniões dos jovens frequentemente são ignoradas devido à baixa participação política, mas essa mudança pode deixar consequências duradouras, impactando muito mais do que apenas os resultados das eleições.

... something else

This is the final image. Or is it? Likely, it is not. I have already started on a perfect version of my Mother Earth painting.

Of course, there is no such thing as a perfect painting. What I mean is that I already started on a vector version of Mother Earth. You're familiar with vector vs. pixel, right?

But let's start at the beginning, not the end.

This here is a pic from the sketching phase. I am not one who can just magically and with a few strokes produce an amazing sketch of something that resembles a human. There are artists out there that do this wonderfully. It's amazing but it is not me (unfortunately).

Here I am starting to color in the sketch with a watercolor brush. This is all done in Procreate App on an iPad Pro. The coloring is on a separate layer with the pencil sketch set to multiply to shine through the colors. That's why the pencil strokes now are black. I like that look.

And here, I am almost done. Just need to decide on the background color. And as you can see from the gif and video I didn't really decide. Though at the moment I am favoring that muted pinkish red - LOL

Which color is your favorite?

Here you can see the whole process in a timelapse. Above pictures were grabbed from it to detail the process a little.

And that's it my Nostr friends for my first longform post in this community.

I hope you enjoyed this post. Comments are encouraged an appreciated. Thank you.

Was du bist hängt von drei Faktoren ab: \ Was du geerbt hast, \ was deine Umgebung aus dir machte \ und was du in freier Wahl \ aus deiner Umgebung und deinem Erbe gemacht hast. \ Aldous Huxley

Das brave Mitmachen und Mitlaufen in einem vorgegebenen, recht engen Rahmen ist gewiss nicht neu, hat aber gerade wieder mal Konjunktur. Dies kann man deutlich beobachten, eigentlich egal, in welchem gesellschaftlichen Bereich man sich umschaut. Individualität ist nur soweit angesagt, wie sie in ein bestimmtes Schema von «Diversität» passt, und Freiheit verkommt zur Worthülse – nicht erst durch ein gewisses Buch einer gewissen ehemaligen Regierungschefin.

Erklärungsansätze für solche Entwicklungen sind bekannt, und praktisch alle haben etwas mit Massenpsychologie zu tun. Der Herdentrieb, also der Trieb der Menschen, sich – zum Beispiel aus Unsicherheit oder Bequemlichkeit – lieber der Masse anzuschließen als selbstständig zu denken und zu handeln, ist einer der Erklärungsversuche. Andere drehen sich um Macht, Propaganda, Druck und Angst, also den gezielten Einsatz psychologischer Herrschaftsinstrumente.

Aber wollen die Menschen überhaupt Freiheit? Durch Gespräche im privaten Umfeld bin ich diesbezüglich in der letzten Zeit etwas skeptisch geworden. Um die Jahreswende philosophiert man ja gerne ein wenig über das Erlebte und über die Erwartungen für die Zukunft. Dabei hatte ich hin und wieder den Eindruck, die totalitären Anwandlungen unserer «Repräsentanten» kämen manchen Leuten gerade recht.

«Desinformation» ist so ein brisantes Thema. Davor müsse man die Menschen doch schützen, hörte ich. Jemand müsse doch zum Beispiel diese ganzen merkwürdigen Inhalte in den Social Media filtern – zur Ukraine, zum Klima, zu Gesundheitsthemen oder zur Migration. Viele wüssten ja gar nicht einzuschätzen, was richtig und was falsch ist, sie bräuchten eine Führung.

Freiheit bedingt Eigenverantwortung, ohne Zweifel. Eventuell ist es einigen tatsächlich zu anspruchsvoll, die Verantwortung für das eigene Tun und Lassen zu übernehmen. Oder die persönliche Freiheit wird nicht als ausreichend wertvolles Gut angesehen, um sich dafür anzustrengen. In dem Fall wäre die mangelnde Selbstbestimmung wohl das kleinere Übel. Allerdings fehlt dann gemäß Aldous Huxley ein Teil der Persönlichkeit. Letztlich ist natürlich alles eine Frage der Abwägung.

Sind viele Menschen möglicherweise schon so «eingenordet», dass freiheitliche Ambitionen gar nicht für eine ganze Gruppe, ein Kollektiv, verfolgt werden können? Solche Gedanken kamen mir auch, als ich mir kürzlich diverse Talks beim viertägigen Hacker-Kongress des Chaos Computer Clubs (38C3) anschaute. Ich war nicht nur überrascht, sondern reichlich erschreckt angesichts der in weiten Teilen mainstream-geformten Inhalte, mit denen ein dankbares Publikum beglückt wurde. Wo ich allgemein hellere Köpfe erwartet hatte, fand ich Konformismus und enthusiastisch untermauerte Narrative.

Gibt es vielleicht so etwas wie eine Herdenimmunität gegen Indoktrination? Ich denke, ja, zumindest eine gestärkte Widerstandsfähigkeit. Was wir brauchen, sind etwas gesunder Menschenverstand, offene Informationskanäle und der Mut, sich freier auch zwischen den Herden zu bewegen. Sie tun das bereits, aber sagen Sie es auch dieses Jahr ruhig weiter.

If one knows exactly what to do to alleviate one's pain, comfort oneself, and emerge more or less unscathed from Adversity, I think it can be said that one has reached a fairly high level of Wisdom in Life.

In 2018 I started doing film photography. I asked myself what could I do that was unique. So, I tried taking picture at local gig venues. I’d look around and everyone was using digital cameras. I had a limited number of shots I could take, inconsistent lighting at different venues but some delayed gratification of not knowing how the images would turn out until I developed them. I’d come home late from a show and be up until the early hours developing and scanning the images. 2020 put a stop to that. It’s something I’d like to start again. I’ll be sharing some of my favourite images I from my badly categorised/labled folders. Artist in photo is called Conner Youngblood. It’s been interesting to listen to his most recent projects (Cascades, Cascading, Cascadingly) to compare to his earlier ones (Australia)

Australia is a stripped back, couple guitars, vox and drums. Most recent has a few more vocal effects and electronica sounds. A comparison I would make would be Bon Iver’s - Emma with their 3rd album 22, a million.

As a when I arrange the files on my HD, I’ll be share a few more band photos.

Heute möchte ich ein Gedicht mit euch teilen. Es handelt sich um eine Ballade des österreichischen Lyrikers Johann Gabriel Seidl aus dem 19. Jahrhundert. Mir sind diese Worte fest in Erinnerung, da meine Mutter sie perfekt rezitieren konnte, auch als die Kräfte schon langsam schwanden.

Dem originalen Titel «Die Uhr» habe ich für mich immer das Wort «innere» hinzugefügt. Denn der Zeitmesser – hier vermutliche eine Taschenuhr – symbolisiert zwar in dem Kontext das damalige Zeitempfinden und die Umbrüche durch die industrielle Revolution, sozusagen den Zeitgeist und das moderne Leben. Aber der Autor setzt sich philosophisch mit der Zeit auseinander und gibt seinem Werk auch eine klar spirituelle Dimension.

Das Ticken der Uhr und die Momente des Glücks und der Trauer stehen sinnbildlich für das unaufhaltsame Fortschreiten und die Vergänglichkeit des Lebens. Insofern könnte man bei der Uhr auch an eine Sonnenuhr denken. Der Rhythmus der Ereignisse passt uns vielleicht nicht immer in den Kram.

Was den Takt pocht, ist durchaus auch das Herz, unser «inneres Uhrwerk». Wenn dieses Meisterwerk einmal stillsteht, ist es unweigerlich um uns geschehen. Hoffentlich können wir dann dankbar sagen: «Ich habe mein Bestes gegeben.»

Ich trage, wo ich gehe, stets eine Uhr bei mir; \ Wieviel es geschlagen habe, genau seh ich an ihr. \ Es ist ein großer Meister, der künstlich ihr Werk gefügt, \ Wenngleich ihr Gang nicht immer dem törichten Wunsche genügt.

Ich wollte, sie wäre rascher gegangen an manchem Tag; \ Ich wollte, sie hätte manchmal verzögert den raschen Schlag. \ In meinen Leiden und Freuden, in Sturm und in der Ruh, \ Was immer geschah im Leben, sie pochte den Takt dazu.

Sie schlug am Sarge des Vaters, sie schlug an des Freundes Bahr, \ Sie schlug am Morgen der Liebe, sie schlug am Traualtar. \ Sie schlug an der Wiege des Kindes, sie schlägt, will's Gott, noch oft, \ Wenn bessere Tage kommen, wie meine Seele es hofft.

Und ward sie auch einmal träger, und drohte zu stocken ihr Lauf, \ So zog der Meister immer großmütig sie wieder auf. \ Doch stände sie einmal stille, dann wär's um sie geschehn, \ Kein andrer, als der sie fügte, bringt die Zerstörte zum Gehn.

Dann müßt ich zum Meister wandern, der wohnt am Ende wohl weit, \ Wohl draußen, jenseits der Erde, wohl dort in der Ewigkeit! \ Dann gäb ich sie ihm zurücke mit dankbar kindlichem Flehn: \ Sieh, Herr, ich hab nichts verdorben, sie blieb von selber stehn.

Johann Gabriel Seidl (1804-1875)

1. Introduction to Consensus in Bitcoin

Consensus in Bitcoin is the foundation that keeps the network secure and functional, allowing users worldwide to perform transactions in a decentralized manner without the need for intermediaries. Since its launch in 2009, Bitcoin is often described as an "immutable" system designed to resist changes, and it is precisely this resistance that ensures its security and stability.

The central idea behind consensus in Bitcoin is to create a set of acceptance rules for blocks and transactions, ensuring that all network participants agree on the transaction history. This prevents "double-spending," where the same bitcoin could be used in two simultaneous transactions, something that would compromise trust in the network.

Evolution of Consensus in Bitcoin

Over the years, consensus in Bitcoin has undergone several adaptations, and the way participants agree on changes remains a delicate process. Unlike traditional systems, where changes can be imposed from the top down, Bitcoin operates in a decentralized model where any significant change needs the support of various groups of stakeholders, including miners, developers, users, and large node operators.

Moreover, the update process is extremely cautious, as hasty changes can compromise the network's security. As a result, the philosophy of "don't fix what isn't broken" prevails, with improvements happening incrementally and only after broad consensus among those involved. This model can make progress seem slow but ensures that Bitcoin remains faithful to the principles of security and decentralization.

2. Technical Components of Consensus

Bitcoin's consensus is supported by a set of technical rules that determine what is considered a valid transaction and a valid block on the network. These technical aspects ensure that all nodes—the computers that participate in the Bitcoin network—agree on the current state of the blockchain. Below are the main technical components that form the basis of the consensus.

Validation of Blocks and Transactions

The validation of blocks and transactions is the central point of consensus in Bitcoin. A block is only considered valid if it meets certain criteria, such as maximum size, transaction structure, and the solving of the "Proof of Work" problem. The proof of work, required for a block to be included in the blockchain, is a computational process that ensures the block contains significant computational effort—protecting the network against manipulation attempts.

Transactions, in turn, need to follow specific input and output rules. Each transaction includes cryptographic signatures that prove the ownership of the bitcoins sent, as well as validation scripts that verify if the transaction conditions are met. This validation system is essential for network nodes to autonomously confirm that each transaction follows the rules.

Chain Selection

Another fundamental technical issue for Bitcoin's consensus is chain selection, which becomes especially important in cases where multiple versions of the blockchain coexist, such as after a network split (fork). To decide which chain is the "true" one and should be followed, the network adopts the criterion of the highest accumulated proof of work. In other words, the chain with the highest number of valid blocks, built with the greatest computational effort, is chosen by the network as the official one.

This criterion avoids permanent splits because it encourages all nodes to follow the same main chain, reinforcing consensus.

Soft Forks vs. Hard Forks

In the consensus process, protocol changes can happen in two ways: through soft forks or hard forks. These variations affect not only the protocol update but also the implications for network users:
- Soft Forks: These are changes that are backward compatible. Only nodes that adopt the new update will follow the new rules, but old nodes will still recognize the blocks produced with these rules as valid. This compatibility makes soft forks a safer option for updates, as it minimizes the risk of network division.
- Hard Forks: These are updates that are not backward compatible, requiring all nodes to update to the new version or risk being separated from the main chain. Hard forks can result in the creation of a new coin, as occurred with the split between Bitcoin and Bitcoin Cash in 2017. While hard forks allow for deeper changes, they also bring significant risks of network fragmentation.
These technical components form the base of Bitcoin's security and resilience, allowing the system to remain functional and immutable without losing the necessary flexibility to evolve over time.

3. Stakeholders in Bitcoin's Consensus

Consensus in Bitcoin is not decided centrally. On the contrary, it depends on the interaction between different groups of stakeholders, each with their motivations, interests, and levels of influence. These groups play fundamental roles in how changes are implemented or rejected on the network. Below, we explore the six main stakeholders in Bitcoin's consensus.

1. Economic Nodes

Economic nodes, usually operated by exchanges, custody providers, and large companies that accept Bitcoin, exert significant influence over consensus. Because they handle large volumes of transactions and act as a connection point between the Bitcoin ecosystem and the traditional financial system, these nodes have the power to validate or reject blocks and to define which version of the software to follow in case of a fork.

Their influence is proportional to the volume of transactions they handle, and they can directly affect which chain will be seen as the main one. Their incentive is to maintain the network's stability and security to preserve its functionality and meet regulatory requirements.

2. Investors

Investors, including large institutional funds and individual Bitcoin holders, influence consensus indirectly through their impact on the asset's price. Their buying and selling actions can affect Bitcoin's value, which in turn influences the motivation of miners and other stakeholders to continue investing in the network's security and development.

Some institutional investors have agreements with custodians that may limit their ability to act in network split situations. Thus, the impact of each investor on consensus can vary based on their ownership structure and how quickly they can react to a network change.

3. Media Influencers

Media influencers, including journalists, analysts, and popular personalities on social media, have a powerful role in shaping public opinion about Bitcoin and possible updates. These influencers can help educate the public, promote debates, and bring transparency to the consensus process.

On the other hand, the impact of influencers can be double-edged: while they can clarify complex topics, they can also distort perceptions by amplifying or minimizing change proposals. This makes them a force both of support and resistance to consensus.

4. Miners

Miners are responsible for validating transactions and including blocks in the blockchain. Through computational power (hashrate), they also exert significant influence over consensus decisions. In update processes, miners often signal their support for a proposal, indicating that the new version is safe to use. However, this signaling is not always definitive, and miners can change their position if they deem it necessary.

Their incentive is to maximize returns from block rewards and transaction fees, as well as to maintain the value of investments in their specialized equipment, which are only profitable if the network remains stable.

5. Protocol Developers

Protocol developers, often called "Core Developers," are responsible for writing and maintaining Bitcoin's code. Although they do not have direct power over consensus, they possess an informal veto power since they decide which changes are included in the main client (Bitcoin Core). This group also serves as an important source of technical knowledge, helping guide decisions and inform other stakeholders.

Their incentive lies in the continuous improvement of the network, ensuring security and decentralization. Many developers are funded by grants and sponsorships, but their motivations generally include a strong ideological commitment to Bitcoin's principles.

6. Users and Application Developers

This group includes people who use Bitcoin in their daily transactions and developers who build solutions based on the network, such as wallets, exchanges, and payment platforms. Although their power in consensus is less than that of miners or economic nodes, they play an important role because they are responsible for popularizing Bitcoin's use and expanding the ecosystem.

If application developers decide not to adopt an update, this can affect compatibility and widespread acceptance. Thus, they indirectly influence consensus by deciding which version of the protocol to follow in their applications.

These stakeholders are vital to the consensus process, and each group exerts influence according to their involvement, incentives, and ability to act in situations of change. Understanding the role of each makes it clearer how consensus is formed and why it is so difficult to make significant changes to Bitcoin.

4. Mechanisms for Activating Updates in Bitcoin

For Bitcoin to evolve without compromising security and consensus, different mechanisms for activating updates have been developed over the years. These mechanisms help coordinate changes among network nodes to minimize the risk of fragmentation and ensure that updates are implemented in an orderly manner. Here, we explore some of the main methods used in Bitcoin, their advantages and disadvantages, as well as historical examples of significant updates.

Flag Day

The Flag Day mechanism is one of the simplest forms of activating changes. In it, a specific date or block is determined as the activation moment, and all nodes must be updated by that point. This method does not involve prior signaling; participants simply need to update to the new software version by the established day or block.
- Advantages: Simplicity and predictability are the main benefits of Flag Day, as everyone knows the exact activation date.
- Disadvantages: Inflexibility can be a problem because there is no way to adjust the schedule if a significant part of the network has not updated. This can result in network splits if a significant number of nodes are not ready for the update.
An example of Flag Day was the Pay to Script Hash (P2SH) update in 2012, which required all nodes to adopt the change to avoid compatibility issues.

BIP34 and BIP9

BIP34 introduced a more dynamic process, in which miners increase the version number in block headers to signal the update. When a predetermined percentage of the last blocks is mined with this new version, the update is automatically activated. This model later evolved with BIP9, which allowed multiple updates to be signaled simultaneously through "version bits," each corresponding to a specific change.
- Advantages: Allows the network to activate updates gradually, giving more time for participants to adapt.
- Disadvantages: These methods rely heavily on miner support, which means that if a sufficient number of miners do not signal the update, it can be delayed or not implemented.
BIP9 was used in the activation of SegWit (BIP141) but faced challenges because some miners did not signal their intent to activate, leading to the development of new mechanisms.

User Activated Soft Forks (UASF) and User Resisted Soft Forks (URSF)

To increase the decision-making power of ordinary users, the concept of User Activated Soft Fork (UASF) was introduced, allowing node operators, not just miners, to determine consensus for a change. In this model, nodes set a date to start rejecting blocks that are not in compliance with the new update, forcing miners to adapt or risk having their blocks rejected by the network.

URSF, in turn, is a model where nodes reject blocks that attempt to adopt a specific update, functioning as resistance against proposed changes.
- Advantages: UASF returns decision-making power to node operators, ensuring that changes do not depend solely on miners.
- Disadvantages: Both UASF and URSF can generate network splits, especially in cases of strong opposition among different stakeholders.
An example of UASF was the activation of SegWit in 2017, where users supported activation independently of miner signaling, which ended up forcing its adoption.

BIP8 (LOT=True)

BIP8 is an evolution of BIP9, designed to prevent miners from indefinitely blocking a change desired by the majority of users and developers. BIP8 allows setting a parameter called "lockinontimeout" (LOT) as true, which means that if the update has not been fully signaled by a certain point, it is automatically activated.
- Advantages: Ensures that changes with broad support among users are not blocked by miners who wish to maintain the status quo.
- Disadvantages: Can lead to network splits if miners or other important stakeholders do not support the update.
Although BIP8 with LOT=True has not yet been used in Bitcoin, it is a proposal that can be applied in future updates if necessary.

These activation mechanisms have been essential for Bitcoin's development, allowing updates that keep the network secure and functional. Each method brings its own advantages and challenges, but all share the goal of preserving consensus and network cohesion.

5. Risks and Considerations in Consensus Updates

Consensus updates in Bitcoin are complex processes that involve not only technical aspects but also political, economic, and social considerations. Due to the network's decentralized nature, each change brings with it a set of risks that need to be carefully assessed. Below, we explore some of the main challenges and future scenarios, as well as the possible impacts on stakeholders.

Network Fragility with Alternative Implementations

One of the main risks associated with consensus updates is the possibility of network fragmentation when there are alternative software implementations. If an update is implemented by a significant group of nodes but rejected by others, a network split (fork) can occur. This creates two competing chains, each with a different version of the transaction history, leading to unpredictable consequences for users and investors.

Such fragmentation weakens Bitcoin because, by dividing hashing power (computing) and coin value, it reduces network security and investor confidence. A notable example of this risk was the fork that gave rise to Bitcoin Cash in 2017 when disagreements over block size resulted in a new chain and a new asset.

Chain Splits and Impact on Stakeholders

Chain splits are a significant risk in update processes, especially in hard forks. During a hard fork, the network is split into two separate chains, each with its own set of rules. This results in the creation of a new coin and leaves users with duplicated assets on both chains. While this may seem advantageous, in the long run, these splits weaken the network and create uncertainties for investors.

Each group of stakeholders reacts differently to a chain split:
- Institutional Investors and ETFs: Face regulatory and compliance challenges because many of these assets are managed under strict regulations. The creation of a new coin requires decisions to be made quickly to avoid potential losses, which may be hampered by regulatory constraints.
- Miners: May be incentivized to shift their computing power to the chain that offers higher profitability, which can weaken one of the networks.
- Economic Nodes: Such as major exchanges and custody providers, have to quickly choose which chain to support, influencing the perceived value of each network.
Such divisions can generate uncertainties and loss of value, especially for institutional investors and those who use Bitcoin as a store of value.

Regulatory Impacts and Institutional Investors

With the growing presence of institutional investors in Bitcoin, consensus changes face new compliance challenges. Bitcoin ETFs, for example, are required to follow strict rules about which assets they can include and how chain split events should be handled. The creation of a new asset or migration to a new chain can complicate these processes, creating pressure for large financial players to quickly choose a chain, affecting the stability of consensus.

Moreover, decisions regarding forks can influence the Bitcoin futures and derivatives market, affecting perception and adoption by new investors. Therefore, the need to avoid splits and maintain cohesion is crucial to attract and preserve the confidence of these investors.

Security Considerations in Soft Forks and Hard Forks

While soft forks are generally preferred in Bitcoin for their backward compatibility, they are not without risks. Soft forks can create different classes of nodes on the network (updated and non-updated), which increases operational complexity and can ultimately weaken consensus cohesion. In a network scenario with fragmentation of node classes, Bitcoin's security can be affected, as some nodes may lose part of the visibility over updated transactions or rules.

In hard forks, the security risk is even more evident because all nodes need to adopt the new update to avoid network division. Experience shows that abrupt changes can create temporary vulnerabilities, in which malicious agents try to exploit the transition to attack the network.

Bounty Claim Risks and Attack Scenarios

Another risk in consensus updates are so-called "bounty claims"—accumulated rewards that can be obtained if an attacker manages to split or deceive a part of the network. In a conflict scenario, a group of miners or nodes could be incentivized to support a new update or create an alternative version of the software to benefit from these rewards.

These risks require stakeholders to carefully assess each update and the potential vulnerabilities it may introduce. The possibility of "bounty claims" adds a layer of complexity to consensus because each interest group may see a financial opportunity in a change that, in the long term, may harm network stability.

The risks discussed above show the complexity of consensus in Bitcoin and the importance of approaching it gradually and deliberately. Updates need to consider not only technical aspects but also economic and social implications, in order to preserve Bitcoin's integrity and maintain trust among stakeholders.

6. Recommendations for the Consensus Process in Bitcoin

To ensure that protocol changes in Bitcoin are implemented safely and with broad support, it is essential that all stakeholders adopt a careful and coordinated approach. Here are strategic recommendations for evaluating, supporting, or rejecting consensus updates, considering the risks and challenges discussed earlier, along with best practices for successful implementation.

1. Careful Evaluation of Proposal Maturity

Stakeholders should rigorously assess the maturity level of a proposal before supporting its implementation. Updates that are still experimental or lack a robust technical foundation can expose the network to unnecessary risks. Ideally, change proposals should go through an extensive testing phase, have security audits, and receive review and feedback from various developers and experts.

2. Extensive Testing in Secure and Compatible Networks

Before an update is activated on the mainnet, it is essential to test it on networks like testnet and signet, and whenever possible, on other compatible networks that offer a safe and controlled environment to identify potential issues. Testing on networks like Litecoin was fundamental for the safe launch of innovations like SegWit and the Lightning Network, allowing functionalities to be validated on a lower-impact network before being implemented on Bitcoin.

The Liquid Network, developed by Blockstream, also plays an important role as an experimental network for new proposals, such as OP_CAT. By adopting these testing environments, stakeholders can mitigate risks and ensure that the update is reliable and secure before being adopted by the main network.

3. Importance of Stakeholder Engagement

The success of a consensus update strongly depends on the active participation of all stakeholders. This includes economic nodes, miners, protocol developers, investors, and end users. Lack of participation can lead to inadequate decisions or even future network splits, which would compromise Bitcoin's security and stability.

4. Key Questions for Evaluating Consensus Proposals

To assist in decision-making, each group of stakeholders should consider some key questions before supporting a consensus change:
- Does the proposal offer tangible benefits for Bitcoin's security, scalability, or usability?
- Does it maintain backward compatibility or introduce the risk of network split?
- Are the implementation requirements clear and feasible for each group involved?
- Are there clear and aligned incentives for all stakeholder groups to accept the change?
5. Coordination and Timing in Implementations

Timing is crucial. Updates with short activation windows can force a split because not all nodes and miners can update simultaneously. Changes should be planned with ample deadlines to allow all stakeholders to adjust their systems, avoiding surprises that could lead to fragmentation.

Mechanisms like soft forks are generally preferable to hard forks because they allow a smoother transition. Opting for backward-compatible updates when possible facilitates the process and ensures that nodes and miners can adapt without pressure.

6. Continuous Monitoring and Re-evaluation

After an update, it's essential to monitor the network to identify problems or side effects. This continuous process helps ensure cohesion and trust among all participants, keeping Bitcoin as a secure and robust network.

These recommendations, including the use of secure networks for extensive testing, promote a collaborative and secure environment for Bitcoin's consensus process. By adopting a deliberate and strategic approach, stakeholders can preserve Bitcoin's value as a decentralized and censorship-resistant network.

7. Conclusion

Consensus in Bitcoin is more than a set of rules; it's the foundation that sustains the network as a decentralized, secure, and reliable system. Unlike centralized systems, where decisions can be made quickly, Bitcoin requires a much more deliberate and cooperative approach, where the interests of miners, economic nodes, developers, investors, and users must be considered and harmonized. This governance model may seem slow, but it is fundamental to preserving the resilience and trust that make Bitcoin a global store of value and censorship-resistant.

Consensus updates in Bitcoin must balance the need for innovation with the preservation of the network's core principles. The development process of a proposal needs to be detailed and rigorous, going through several testing stages, such as in testnet, signet, and compatible networks like Litecoin and Liquid Network. These networks offer safe environments for proposals to be analyzed and improved before being launched on the main network.

Each proposed change must be carefully evaluated regarding its maturity, impact, backward compatibility, and support among stakeholders. The recommended key questions and appropriate timing are critical to ensure that an update is adopted without compromising network cohesion. It's also essential that the implementation process is continuously monitored and re-evaluated, allowing adjustments as necessary and minimizing the risk of instability.

By following these guidelines, Bitcoin's stakeholders can ensure that the network continues to evolve safely and robustly, maintaining user trust and further solidifying its role as one of the most resilient and innovative digital assets in the world. Ultimately, consensus in Bitcoin is not just a technical issue but a reflection of its community and the values it represents: security, decentralization, and resilience.

This century has known a stunning decrease in global income inequality, bringing it down to levels not seen in well over a century. That's the conclusion that Branko Milanovic, one of the world's foremost inequality researchers, comes to in an important essay for Foreign Affairs.

President Trump plans to withdraw 20,000 U.S. troops from Europe and expects European allies to contribute financially to the remaining military presence. Reported by ANSA, Trump aims to deliver this message to European leaders since taking office. A European diplomat noted, “the costs cannot be borne solely by American taxpayers.”

The Pentagon hasn't commented yet. Trump has previously sought lower troop levels in Europe and had ordered cuts during his first term. The U.S. currently maintains around 65,000 troops in Europe, with total forces reaching 100,000 since the Ukraine invasion. Trump's new approach may shift military focus to the Pacific amid growing concerns about China.

So many of our problems are due to our point of view. The closer our point of view gets to God, the more peace and joy we will feel.

Too often we look at God as the big, bad killjoy. We resent when He tells us all the “fun” things we aren’t supposed to do and when He tells us to do difficult things like submit to God, submit to husbands, submit to authorities. Too many people focus on the “do nots,” and don’t like the idea of anyone telling them what to do. They then do their own thing, which they think will make them happy. Unfortunately, this leads to the opposite.

God is our Creator. He created us for a purpose within the rest of His creation.

For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them. (Ephesians 2:10)

When we are doing His will we will find peace and joy. When we fight Him on what we should and should not be doing, we feel frustration, depression, and even despair. Our constant seeking of things to make us happy is actually our innate desire for God and to fulfill His will. Unfortunately, we frequently don’t see the truth and avoid the one thing that will give us peace because it is hard, inconvenient, and doesn’t lead to what we think we want right now.

God wants what is best for us. He also thinks eternally. He doesn’t think in the here and now, like we do. Just as a parent makes decisions for his/her child based on knowledge of what will be better for them in the long term (saving vs spending, healthy food vs junk food, etc.), God makes decisions for us based on what will best prepare us for eternity with Him. Frequently that looks much different than what we think we want. Frequently that even includes hardship and pain because we are much more likely to grow in faith, strength, and holiness during hardship than we do during comfort. We need to understand that God knows best and that He never makes a mistake.

Trust in the Lord with all your heart\ And do not lean on your own understanding.\ In all your ways acknowledge Him,\ And He will make your paths straight.\ Do not be wise in your own eyes;\ Fear the Lord and turn away from evil.\ It will be healing to your body\ And refreshment to your bones. (Proverbs 3:5-8)

Nothing happens on earth without God allowing it. Just as Satan had to ask permission to persecute Job, in the same way nobody can cause believers harm without God allowing it for His purpose, which is usually related to helping them to put their full trust in Him.

Remember the former things long past,\ For I am God, and there is no other;\ I am God, and there is no one like Me,\ Declaring the end from the beginning,\ And from ancient times things which have not been done,\ Saying, ‘My purpose will be established,\ And I will accomplish all My good pleasure’; (Isaiah 46:9-10)

So often I focus on how awesome, powerful, and holy our God is. He is also the most tender, loving, caring, personal father God. Read Psalm 139. The God of the Bible is not a distant clock maker who set the world in motion and let it go about without His care. He is personally involved in everything that happens and in the life of every person on earth, but especially in the life of those who trust in Him.

O Lord, You have searched me and known me.\ You know when I sit down and when I rise up;\ You understand my thought from afar.\ You scrutinize my path and my lying down,\ *And are intimately acquainted with all my ways.\ Even before there is a word on my tongue,\ Behold, O Lord, You know it all.*\ You have enclosed me behind and before,\ And laid Your hand upon me.\ Such knowledge is too wonderful for me;\ It is too high, I cannot attain to it.\ Where can I go from Your Spirit?\ Or where can I flee from Your presence?\ If I ascend to heaven, You are there;\ If I make my bed in Sheol, behold, You are there.\ If I take the wings of the dawn,\ If I dwell in the remotest part of the sea,\ *Even there Your hand will lead me*,\ And Your right hand will lay hold of me.\ If I say, “Surely the darkness will overwhelm me,\ And the light around me will be night,”\ Even the darkness is not dark to You,\ And the night is as bright as the day.\ Darkness and light are alike to You.\ For You formed my inward parts;\ You wove me in my mother’s womb.\ I will give thanks to You, for I am fearfully and wonderfully made;\ Wonderful are Your works,\ And my soul knows it very well.\ My frame was not hidden from You,\ When I was made in secret,\ And skillfully wrought in the depths of the earth;\ Your eyes have seen my unformed substance;\ And in Your book were all written\ The days that were ordained for me,\ When as yet there was not one of them.\ How precious also are Your thoughts to me, O God!\ How vast is the sum of them!\ If I should count them, they would outnumber the sand.\ When I awake, I am still with You.\ O that You would slay the wicked, O God;\ Depart from me, therefore, men of bloodshed.\ For they speak against You wickedly,\ And Your enemies take Your name in vain.\ Do I not hate those who hate You, O Lord?\ And do I not loathe those who rise up against You?\ I hate them with the utmost hatred;|\ They have become my enemies.\ **Search me, O God, and know my heart;\ Try me and know my anxious thoughts;\ And see if there be any hurtful way in me,\ And lead me in the everlasting way. (Psalm 139) {emphasis mine}

What is one of the greatest desires of our hearts? Isn’t it to be truly known and loved for who we are?

O Lord, You have searched me and known me.\ You know when I sit down and when I rise up;\ You understand my thought from afar. (Psalm 139:1-2)

How amazing is it that the Creator of the universe knows you personally and cares for you among all of creation?

Even before there is a word on my tongue,\ Behold, O Lord, You know it all. (Psalm 139:4)

He knows our every action, our every thought, and our every feeling before we do.

Such knowledge is too wonderful for me;\ It is too high, I cannot attain to it. (Psalm 139:6)

We cannot fully understand how much our Creator cares for us and how carefully God guides us in our every path. We usually can’t see what is for our best. We usually can’t see what great work God is working in us. We usually can’t comprehend how great is His love, knowledge, and plan.

Even there Your hand will lead me,\ And Your right hand will lay hold of me. (Psalm 139:10)

It doesn’t matter how difficult a situation we have gotten into. It doesn’t matter how powerful our adversaries are. It doesn’t matter how weak we are. God is always there guiding us and protecting us. Just as God allowed Job to go through difficulty as part of God’s plan for Job and for us, He did not allow Job to be killed. He was guided through the worst of situations and led to ultimate blessing.

Your eyes have seen my unformed substance;\ And in Your book were all written\ The days that were ordained for me,\ When as yet there was not one of them. (Psalm 139:16)

God knew us and had a plan for us before He even created the universe. He knew every day we would live before we were conceived. We can’t surprise Him and He will be guiding us every day of our lives, especially those who have trusted Him as savior.

How precious also are Your thoughts to me, O God!\ How vast is the sum of them! (Psalm 139:17)

We are precious to God and He should be precious to us because of all He has done for us.

Search me, O God, and know my heart;\ Try me and know my anxious thoughts;\ And see if there be any hurtful way in me,\ And lead me in the everlasting way. (Psalm 139:23-24)

This should be our prayer. We should ask for Him to bring are faults to our minds so we can repent and we should ask for Him to lead us in His “everlasting way.” We should admit that our Father God knows best and submit to His will. Everything goes so much smoother when we aren’t fighting our God. Even when He leads us through hardship, being in His will makes all of the difference in the world.

I pray that you will put your trust in our loving Creator and that you will submit to His will. I pray that you will understand that His ways are better even when you don’t understand the why. I pray that you will humbly submit to His will and be used to further the Kingdom for His glory and your blessing.

Trust Jesus.

FYI, Psalm 139 is also one of the best passages on why all believers should oppose abortion. In God’s universe there are no accidents and there are no unwanted babies. Every person ever conceived had a purpose in God’s plan. Every person ever conceived is valuable and made in the image of God. God values all human life and so should we.

Sometimes I think I'm a bit nihilistic, it can make me sad at times, but at times it also gives me ultimate freedom. What gets you up in the morning?

We’re stardust that somehow became self-aware. The odds of existing are astronomically small—every ancestor in your lineage survived long enough to pass on life, through ice ages, disasters, and chaos. You’re the universe experiencing itself.

The international race for Bitcoin strategic reserves is just getting started.

If you’re stacking now, you’re still incredibly early.

At $100k per Bitcoin, it’s practically free for anyone who truly understands how massive this shift is.

Think back to when paper currency was introduced, people had to trade their gold for paper bills. Many laughed, saying, Who’s going to trust these worthless pieces of paper as money?

Yet today, you sell your time to earn these paper bills while your government can print an unlimited amount at will.

The world is returning to a gold standard. But this time, it’s Gold 2.0 which is Bitcoin.The international race for Bitcoin strategic reserves is just getting started.\ \ If you’re stacking now, you’re still incredibly early.\ \ At $100k per Bitcoin, it’s practically free for anyone who truly understands how massive this shift is.\ \ Think back to when paper currency was introduced, people had to trade their gold for paper bills.

2025-01-30 17:15:37
There was a slight dust up recently over a website someone runs removing a listing for an app someone built based on entirely arbitrary criteria. I'm not to going to attempt to speak for either wounded party, but I would like to share my own personal definition for what constitutes a "nostr app" in an effort to help clarify what might be an otherwise confusing and opaque purity test.

In this post, I will be committing the "no true Scotsman" fallacy, in which I start with the most liberal definition I can come up with, and gradually refine it until all that is left is the purest, gleamingest, most imaginary and unattainable nostr app imaginable. As I write this, I wonder if anything built yet will actually qualify. In any case, here we go.

It uses nostr

The lowest bar for what a "nostr app" might be is an app ("application" - i.e. software, not necessarily a native app of any kind) that has some nostr-specific code in it, but which doesn't take any advantage of what makes nostr distinctive as a protocol.

Examples might include a scraper of some kind which fulfills its charter by fetching data from relays (regardless of whether it validates or retains signatures). Another might be a regular web 2.0 app which provides an option to "log in with nostr" by requesting and storing the user's public key.

In either case, the fact that nostr is involved is entirely neutral. A scraper can scrape html, pdfs, jsonl, whatever data source - nostr relays are just another target. Likewise, a user's key in this scenario is treated merely as an opaque identifier, with no appreciation for the super powers it brings along.

In most cases, this kind of app only exists as a marketing ploy, or less cynically, because it wants to get in on the hype of being a "nostr app", without the developer quite understanding what that means, or having the budget to execute properly on the claim.

It leverages nostr

Some of you might be wondering, "isn't 'leverage' a synonym for 'use'?" And you would be right, but for one connotative difference. It's possible to "use" something improperly, but by definition leverage gives you a mechanical advantage that you wouldn't otherwise have. This is the second category of "nostr app".

This kind of app gets some benefit out of the nostr protocol and network, but in an entirely selfish fashion. The intention of this kind of app is not to augment the nostr network, but to augment its own UX by borrowing some nifty thing from the protocol without really contributing anything back.

Some examples might include:
- Using nostr signers to encrypt or sign data, and then store that data on a proprietary server.
- Using nostr relays as a kind of low-code backend, but using proprietary event payloads.
- Using nostr event kinds to represent data (why), but not leveraging the trustlessness that buys you.
An application in this category might even communicate to its users via nostr DMs - but this doesn't make it a "nostr app" any more than a website that emails you hot deals on herbal supplements is an "email app". These apps are purely parasitic on the nostr ecosystem.

In the long-term, that's not necessarily a bad thing. Email's ubiquity is self-reinforcing. But in the short term, this kind of "nostr app" can actually do damage to nostr's reputation by over-promising and under-delivering.

It complements nostr

Next up, we have apps that get some benefit out of nostr as above, but give back by providing a unique value proposition to nostr users as nostr users. This is a bit of a fine distinction, but for me this category is for apps which focus on solving problems that nostr isn't good at solving, leaving the nostr integration in a secondary or supporting role.

One example of this kind of app was Mutiny (RIP), which not only allowed users to sign in with nostr, but also pulled those users' social graphs so that users could send money to people they knew and trusted. Mutiny was doing a great job of leveraging nostr, as well as providing value to users with nostr identities - but it was still primarily a bitcoin wallet, not a "nostr app" in the purest sense.

Other examples are things like Nostr Nests and Zap.stream, whose core value proposition is streaming video or audio content. Both make great use of nostr identities, data formats, and relays, but they're primarily streaming apps. A good litmus test for things like this is: if you got rid of nostr, would it be the same product (even if inferior in certain ways)?

A similar category is infrastructure providers that benefit nostr by their existence (and may in fact be targeted explicitly at nostr users), but do things in a centralized, old-web way; for example: media hosts, DNS registrars, hosting providers, and CDNs.

To be clear here, I'm not casting aspersions (I don't even know what those are, or where to buy them). All the apps mentioned above use nostr to great effect, and are a real benefit to nostr users. But they are not True Scotsmen.

It embodies nostr

Ok, here we go. This is the crème de la crème, the top du top, the meilleur du meilleur, the bee's knees. The purest, holiest, most chaste category of nostr app out there. The apps which are, indeed, nostr indigitate.

This category of nostr app (see, no quotes this time) can be defined by the converse of the previous category. If nostr was removed from this type of application, would it be impossible to create the same product?

To tease this apart a bit, apps that leverage the technical aspects of nostr are dependent on nostr the protocol, while apps that benefit nostr exclusively via network effect are integrated into nostr the network. An app that does both things is working in symbiosis with nostr as a whole.

An app that embraces both nostr's protocol and its network becomes an organic extension of every other nostr app out there, multiplying both its competitive moat and its contribution to the ecosystem:
- In contrast to apps that only borrow from nostr on the technical level but continue to operate in their own silos, an application integrated into the nostr network comes pre-packaged with existing users, and is able to provide more value to those users because of other nostr products. On nostr, it's a good thing to advertise your competitors.
- In contrast to apps that only market themselves to nostr users without building out a deep integration on the protocol level, a deeply integrated app becomes an asset to every other nostr app by becoming an organic extension of them through interoperability. This results in increased traffic to the app as other developers and users refer people to it instead of solving their problem on their own. This is the "micro-apps" utopia we've all been waiting for.
Credible exit doesn't matter if there aren't alternative services. Interoperability is pointless if other applications don't offer something your app doesn't. Marketing to nostr users doesn't matter if you don't augment their agency as nostr users.

If I had to choose a single NIP that represents the mindset behind this kind of app, it would be NIP 89 A.K.A. "Recommended Application Handlers", which states:

Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics. This NIP provides a simple way for clients to discover applications that handle events of a specific kind to ensure smooth cross-client and cross-kind interactions.

These handlers are the glue that holds nostr apps together. A single event, signed by the developer of an application (or by the application's own account) tells anyone who wants to know 1. what event kinds the app supports, 2. how to link to the app (if it's a client), and (if the pubkey also publishes a kind 10002), 3. which relays the app prefers.

As a sidenote, NIP 89 is currently focused more on clients, leaving DVMs, relays, signers, etc somewhat out in the cold. Updating 89 to include tailored listings for each kind of supporting app would be a huge improvement to the protocol. This, plus a good front end for navigating these listings (sorry nostrapp.link, close but no cigar) would obviate the evil centralized websites that curate apps based on arbitrary criteria.

Examples of this kind of app obviously include many kind 1 clients, as well as clients that attempt to bring the benefits of the nostr protocol and network to new use cases - whether long form content, video, image posts, music, emojis, recipes, project management, or any other "content type".

To drill down into one example, let's think for a moment about forms. What's so great about a forms app that is built on nostr? Well,
- There is a spec for forms and responses, which means that...
- Multiple clients can implement the same data format, allowing for credible exit and user choice, even of...
- Other products not focused on forms, which can still view, respond to, or embed forms, and which can send their users via NIP 89 to a client that does...
- Cryptographically sign forms and responses, which means they are self-authenticating and can be sent to...
- Multiple relays, which reduces the amount of trust necessary to be confident results haven't been deliberately "lost".
Show me a forms product that does all of those things, and isn't built on nostr. You can't, because it doesn't exist. Meanwhile, there are plenty of image hosts with APIs, streaming services, and bitcoin wallets which have basically the same levels of censorship resistance, interoperability, and network effect as if they weren't built on nostr.

It supports nostr

Notice I haven't said anything about whether relays, signers, blossom servers, software libraries, DVMs, and the accumulated addenda of the nostr ecosystem are nostr apps. Well, they are (usually).

This is the category of nostr app that gets none of the credit for doing all of the work. There's no question that they qualify as beautiful nostrcorns, because their value propositions are entirely meaningless outside of the context of nostr. Who needs a signer if you don't have a cryptographic identity you need to protect? DVMs are literally impossible to use without relays. How are you going to find the blossom server that will serve a given hash if you don't know which servers the publishing user has selected to store their content?

In addition to being entirely contextualized by nostr architecture, this type of nostr app is valuable because it does things "the nostr way". By that I mean that they don't simply try to replicate existing internet functionality into a nostr context; instead, they create entirely new ways of putting the basic building blocks of the internet back together.

A great example of this is how Nostr Connect, Nostr Wallet Connect, and DVMs all use relays as brokers, which allows service providers to avoid having to accept incoming network connections. This opens up really interesting possibilities all on its own.

So while I might hesitate to call many of these things "apps", they are certainly "nostr".

Appendix: it smells like a NINO

So, let's say you've created an app, but when you show it to people they politely smile, nod, and call it a NINO (Nostr In Name Only). What's a hacker to do? Well, here's your handy-dandy guide on how to wash that NINO stench off and Become a Nostr.

You app might be a NINO if:
- There's no NIP for your data format (or you're abusing NIP 78, 32, etc by inventing a sub-protocol inside an existing event kind)
- There's a NIP, but no one knows about it because it's in a text file on your hard drive (or buried in your project's repository)
- Your NIP imposes an incompatible/centralized/legacy web paradigm onto nostr
- Your NIP relies on trusted third (or first) parties
- There's only one implementation of your NIP (yours)
- Your core value proposition doesn't depend on relays, events, or nostr identities
- One or more relay urls are hard-coded into the source code
- Your app depends on a specific relay implementation to work (ahem, relay29)
- You don't validate event signatures
- You don't publish events to relays you don't control
- You don't read events from relays you don't control
- You use legacy web services to solve problems, rather than nostr-native solutions
- You use nostr-native solutions, but you've hardcoded their pubkeys or URLs into your app
- You don't use NIP 89 to discover clients and services
- You haven't published a NIP 89 listing for your app
- You don't leverage your users' web of trust for filtering out spam
- You don't respect your users' mute lists
- You try to "own" your users' data
Now let me just re-iterate - it's ok to be a NINO. We need NINOs, because nostr can't (and shouldn't) tackle every problem. You just need to decide whether your app, as a NINO, is actually contributing to the nostr ecosystem, or whether you're just using buzzwords to whitewash a legacy web software product.

If you're in the former camp, great! If you're in the latter, what are you waiting for? Only you can fix your NINO problem. And there are lots of ways to do this, depending on your own unique situation:
- Drop nostr support if it's not doing anyone any good. If you want to build a normal company and make some money, that's perfectly fine.
- Build out your nostr integration - start taking advantage of webs of trust, self-authenticating data, event handlers, etc.
- Work around the problem. Think you need a special relay feature for your app to work? Guess again. Consider encryption, AUTH, DVMs, or better data formats.
- Think your idea is a good one? Talk to other devs or open a PR to the nips repo. No one can adopt your NIP if they don't know about it.
- Keep going. It can sometimes be hard to distinguish a research project from a NINO. New ideas have to be built out before they can be fully appreciated.
- Listen to advice. Nostr developers are friendly and happy to help. If you're not sure why you're getting traction, ask!
I sincerely hope this article is useful for all of you out there in NINO land. Maybe this made you feel better about not passing the totally optional nostr app purity test. Or maybe it gave you some actionable next steps towards making a great NINON (Nostr In Not Only Name) app. In either case, GM and PV.

Falls du beim Lesen des Titels dieses Newsletters unwillkürlich an positive Neuigkeiten aus dem globalen polit-medialen Irrenhaus oder gar aus dem wirtschaftlichen Umfeld gedacht hast, darf ich dich beglückwünschen. Diese Assoziation ist sehr löblich, denn sie weist dich als unverbesserlichen Optimisten aus. Leider muss ich dich diesbezüglich aber enttäuschen. Es geht hier um ein anderes Thema, allerdings sehr wohl ein positives, wie ich finde.

Heute ist ein ganz besonderer Tag: die Wintersonnenwende. Genau gesagt hat heute morgen um 10:20 Uhr Mitteleuropäischer Zeit (MEZ) auf der Nordhalbkugel unseres Planeten der astronomische Winter begonnen. Was daran so außergewöhnlich ist? Der kürzeste Tag des Jahres war gestern, seit heute werden die Tage bereits wieder länger! Wir werden also jetzt jeden Tag ein wenig mehr Licht haben.

Für mich ist dieses Ereignis immer wieder etwas kurios: Es beginnt der Winter, aber die Tage werden länger. Das erscheint mir zunächst wie ein Widerspruch, denn meine spontanen Assoziationen zum Winter sind doch eher Kälte und Dunkelheit, relativ zumindest. Umso erfreulicher ist der emotionale Effekt, wenn dann langsam die Erkenntnis durchsickert: Ab jetzt wird es schon wieder heller!

Natürlich ist es kalt im Winter, mancherorts mehr als anderswo. Vielleicht jedoch nicht mehr lange, wenn man den Klimahysterikern glauben wollte. Mindestens letztes Jahr hat Väterchen Frost allerdings gleich zu Beginn seiner Saison – und passenderweise während des globalen Überhitzungsgipfels in Dubai – nochmal richtig mit der Faust auf den Tisch gehauen. Schnee- und Eischaos sind ja eigentlich in der Agenda bereits nicht mehr vorgesehen. Deswegen war man in Deutschland vermutlich in vorauseilendem Gehorsam schon nicht mehr darauf vorbereitet und wurde glatt lahmgelegt.

Aber ich schweife ab. Die Aussicht auf nach und nach mehr Licht und damit auch Wärme stimmt mich froh. Den Zusammenhang zwischen beidem merkt man in Andalusien sehr deutlich. Hier, wo die Häuser im Winter arg auskühlen, geht man zum Aufwärmen raus auf die Straße oder auf den Balkon. Die Sonne hat auch im Winter eine erfreuliche Kraft. Und da ist jede Minute Gold wert.

Außerdem ist mir vor Jahren so richtig klar geworden, warum mir das südliche Klima so sehr gefällt. Das liegt nämlich nicht nur an der Sonne als solcher, oder der Wärme – das liegt vor allem am Licht. Ohne Licht keine Farben, das ist der ebenso simple wie gewaltige Unterschied zwischen einem deprimierenden matschgraubraunen Winter und einem fröhlichen bunten. Ein großes Stück Lebensqualität.

Mir gefällt aber auch die Symbolik dieses Tages: Licht aus der Dunkelheit, ein Wendepunkt, ein Neuanfang, neue Möglichkeiten, Übergang zu neuer Aktivität. In der winterlichen Stille keimt bereits neue Lebendigkeit. Und zwar in einem Zyklus, das wird immer wieder so geschehen. Ich nehme das gern als ein Stück Motivation, es macht mir Hoffnung und gibt mir Energie.

Übrigens ist parallel am heutigen Tag auf der südlichen Halbkugel Sommeranfang. Genau im entgegengesetzten Rhythmus, sich ergänzend, wie Yin und Yang. Das alles liegt an der Schrägstellung der Erdachse, die ist nämlich um 23,4º zur Umlaufbahn um die Sonne geneigt. Wir erinnern uns, gell?

Insofern bleibt eindeutig festzuhalten, dass “schräg sein” ein willkommener, wichtiger und positiver Wert ist. Mit anderen Worten: auch ungewöhnlich, eigenartig, untypisch, wunderlich, kauzig, … ja sogar irre, spinnert oder gar “quer” ist in Ordnung. Das schließt das Denken mit ein.

In diesem Sinne wünsche ich euch allen urige Weihnachtstage!

Dieser Beitrag ist letztes Jahr in meiner Denkbar erschienen.

My best day yet: it's been 17 hours since I ate or drank anything.

I'm about to have my coffee and I'll probably eat soon after that.

I would have gone longer without food yesterday, but we had cookies in the house and I wanted to eat some before I finished my morning coffee.

The big boards are starting to shift around a bit, after seeing the Senior Bowl activities.

Here are the top four players available for me at 6: 1. DE Abdul Carter 2. CB/WR Travis Hunter 3. DT Mason Graham 4. OT Will Campbell

I would be very happy with any of the four. If this were a mock draft with trades, I would definitely trade back a few spots.

Mock Draft

Pick 6: CB/WR/KR/PR Travis Hunter Pick 37: QB Jalen Milroe Pick 68: WR Tre Harris Pick 73: RB Kaleb Johnson Pick 107: OT Earnest Greene Pick 144: LB Jay Higgins Pick 182: OG Garrett Dellenger Pick 214: DE Tyler Batty Pick 218: S Shilo Sanders Pick 224: OG Clay Webb

Once again, the Raiders walk away with the most uniquely talented player in the draft. If anyone will let him play all three phases, it's Pete Carroll.

Then, Milroe is once again there in the 2nd round, so that takes care of the QB need. Is he a good fit for our new OC, Chip Kelly?

The third rounders go towards the skill positions, which will be desperately needed absent a high level QB.

On day 3, the Raiders land Shilo Sanders, continuing our trend of bringing in relatives of HOF DB's.

President Trump has started rolling out his tariffs, something I blogged about in November. People are talking about these tariffs a lot right now, with many people (correctly) commenting on how consumers will end up with higher prices as a result of these tariffs. While that part is true, I’ve seen a lot of people taking it to the next, incorrect step: that consumers will pay the entirety of the tax. I put up a poll on X to see what people thought, and while the right answer got a lot of votes, it wasn't the winner.

For purposes of this blog post, our ultimate question will be the following:
- Suppose apples currently sell for $1 each in the entire United States.
- There are domestic sellers and foreign sellers of apples, all receiving the same price.
- There are no taxes or tariffs on the purchase of apples.
- The question is: if the US federal government puts a $0.50 import tariff per apple, what will be the change in the following:
- Number of apples bought in the US
- Price paid by buyers for apples in the US
- Post-tax price received by domestic apple producers
- Post-tax price received by foreign apple producers
Before we can answer that question, we need to ask an easier, first question: before instituting the tariff, why do apples cost $1?

And finally, before we dive into the details, let me provide you with the answers to the ultimate question. I recommend you try to guess these answers before reading this, and if you get it wrong, try to understand why:
1. The number of apples bought will go down
2. The buyers will pay more for each apple they buy, but not the full amount of the tariff
3. Domestic apple sellers will receive a higher price per apple
4. Foreign apple sellers will receive a lower price per apple, but not lowered by the full amount of the tariff
In other words, regardless of who sends the payment to the government, both taxed parties (domestic buyers and foreign sellers) will absorb some of the costs of the tariff, while domestic sellers will benefit from the protectionism provided by tariffs and be able to sell at a higher price per unit.

Marginal benefit

All of the numbers discussed below are part of a helper Google Sheet I put together for this analysis. Also, apologies about the jagged lines in the charts below, I hadn’t realized before starting on this that there are some difficulties with creating supply and demand charts in Google Sheets.

Let’s say I absolutely love apples, they’re my favorite food. How much would I be willing to pay for a single apple? You might say “$1, that’s the price in the supermarket,” and in many ways you’d be right. If I walk into supermarket A, see apples on sale for $50, and know that I can buy them at supermarket B for $1, I’ll almost certainly leave A and go buy at B.

But that’s not what I mean. What I mean is: how high would the price of apples have to go everywhere so that I’d no longer be willing to buy a single apple? This is a purely personal, subjective opinion. It’s impacted by how much money I have available, other expenses I need to cover, and how much I like apples. But let’s say the number is $5.

How much would I be willing to pay for another apple? Maybe another $5. But how much am I willing to pay for the 1,000th apple? 10,000th? At some point, I’ll get sick of apples, or run out of space to keep the apples, or not be able to eat, cook, and otherwise preserve all those apples before they rot.

The point being: I’ll be progressively willing to spend less and less money for each apple. This form of analysis is called marginal benefit: how much benefit (expressed as dollars I’m willing to spend) will I receive from each apple? This is a downward sloping function: for each additional apple I buy (quantity demanded), the price I’m willing to pay goes down. This is what gives my personal demand curve. And if we aggregate demand curves across all market participants (meaning: everyone interested in buying apples), we end up with something like this:

Assuming no changes in people’s behavior and other conditions in the market, this chart tells us how many apples will be purchased by our buyers at each price point between $0.50 and $5. And ceteris paribus (all else being equal), this will continue to be the demand curve for apples.

Marginal cost

Demand is half the story of economics. The other half is supply, or: how many apples will I sell at each price point? Supply curves are upward sloping: the higher the price, the more a person or company is willing and able to sell a product.

Let’s understand why. Suppose I have an apple orchard. It’s a large property right next to my house. With about 2 minutes of effort, I can walk out of my house, find the nearest tree, pick 5 apples off the tree, and call it a day. 5 apples for 2 minutes of effort is pretty good, right?

Yes, there was all the effort necessary to buy the land, and plant the trees, and water them… and a bunch more than I likely can’t even guess at. We’re going to ignore all of that for our analysis, because for short-term supply-and-demand movement, we can ignore these kinds of sunk costs. One other simplification: in reality, supply curves often start descending before ascending. This accounts for achieving efficiencies of scale after the first number of units purchased. But since both these topics are unneeded for understanding taxes, I won’t go any further.

Anyway, back to my apple orchard. If someone offers me $0.50 per apple, I can do 2 minutes of effort and get $2.50 in revenue, which equates to a $75/hour wage for me. I’m more than happy to pick apples at that price!

However, let’s say someone comes to buy 10,000 apples from me instead. I no longer just walk out to my nearest tree. I’m going to need to get in my truck, drive around, spend the day in the sun, pay for gas, take a day off of my day job (let’s say it pays me $70/hour). The costs go up significantly. Let’s say it takes 5 days to harvest all those apples myself, it costs me $100 in fuel and other expenses, and I lose out on my $70/hour job for 5 days. We end up with:
- Total expenditure: $100 + $70 * 8 hours a day * 5 days \== $2900
- Total revenue: $5000 (10,000 apples at $0.50 each)
- Total profit: $2100
So I’m still willing to sell the apples at this price, but it’s not as attractive as before. And as the number of apples purchased goes up, my costs keep increasing. I’ll need to spend more money on fuel to travel more of my property. At some point I won’t be able to do the work myself anymore, so I’ll need to pay others to work on the farm, and they’ll be slower at picking apples than me (less familiar with the property, less direct motivation, etc.). The point being: at some point, the number of apples can go high enough that the $0.50 price point no longer makes me any money.

This kind of analysis is called marginal cost. It refers to the additional amount of expenditure a seller has to spend in order to produce each additional unit of the good. Marginal costs go up as quantity sold goes up. And like demand curves, if you aggregate this data across all sellers, you get a supply curve like this:

Equilibrium price

We now know, for every price point, how many apples buyers will purchase, and how many apples sellers will sell. Now we find the equilibrium: where the supply and demand curves meet. This point represents where the marginal benefit a buyer would receive from the next buyer would be less than the cost it would take the next seller to make it. Let’s see it in a chart:

You’ll notice that these two graphs cross at the $1 price point, where 63 apples are both demanded (bought by consumers) and supplied (sold by producers). This is our equilibrium price. We also have a visualization of the surplus created by these trades. Everything to the left of the equilibrium point and between the supply and demand curves represents surplus: an area where someone is receiving something of more value than they give. For example:
- When I bought my first apple for $1, but I was willing to spend $5, I made $4 of consumer surplus. The consumer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and above the equilibrium price point.
- When a seller sells his first apple for $1, but it only cost $0.50 to produce it, the seller made $0.50 of producer surplus. The producer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and below the equilibrium price point.
Another way of thinking of surplus is “every time someone got a better price than they would have been willing to take.”

OK, with this in place, we now have enough information to figure out how to price in the tariff, which we’ll treat as a negative externality.

Modeling taxes

Alright, the government has now instituted a $0.50 tariff on every apple sold within the US by a foreign producer. We can generally model taxes by either increasing the marginal cost of each unit sold (shifting the supply curve up), or by decreasing the marginal benefit of each unit bought (shifting the demand curve down). In this case, since only some of the producers will pay the tax, it makes more sense to modify the supply curve.

First, let’s see what happens to the foreign seller-only supply curve when you add in the tariff:

With the tariff in place, for each quantity level, the price at which the seller will sell is $0.50 higher than before the tariff. That makes sense: if I was previously willing to sell my 82nd apple for $3, I would now need to charge $3.50 for that apple to cover the cost of the tariff. We see this as the tariff “pushing up” or “pushing left” the original supply curve.

We can add this new supply curve to our existing (unchanged) supply curve for domestic-only sellers, and we end up with a result like this:

The total supply curve adds up the individual foreign and domestic supply curves. At each price point, we add up the total quantity each group would be willing to sell to determine the total quantity supplied for each price point. Once we have that cumulative supply curve defined, we can produce an updated supply-and-demand chart including the tariff:

As we can see, the equilibrium has shifted:
- The equilibrium price paid by consumers has risen from $1 to $1.20.
- The total number of apples purchased has dropped from 63 apples to 60 apples.
- Consumers therefore received 3 less apples. They spent $72 for these 60 apples, whereas previously they spent $63 for 3 more apples, a definite decrease in consumer surplus.
- Foreign producers sold 36 of those apples (see the raw data in the linked Google Sheet), for a gross revenue of $43.20. However, they also need to pay the tariff to the US government, which accounts for $18, meaning they only receive $25.20 post-tariff. Previously, they sold 42 apples at $1 each with no tariff to be paid, meaning they took home $42.
- Domestic producers sold the remaining 24 apples at $1.20, giving them a revenue of $28.80. Since they don’t pay the tariff, they take home all of that money. By contrast, previously, they sold 21 apples at $1, for a take-home of $21.
- The government receives $0.50 for each of the 60 apples sold, or in other words receives $30 in revenue it wouldn’t have received otherwise.
We could be more specific about the surpluses, and calculate the actual areas for consumer surplus, producer surplus, inefficiency from the tariff, and government revenue from the tariff. But I won’t bother, as those calculations get slightly more involved. Instead, let’s just look at the aggregate outcomes:
- Consumers were unquestionably hurt. Their price paid went up by $0.20 per apple, and received less apples.
- Foreign producers were also hurt. Their price received went down from the original $1 to the new post-tariff price of $1.20, minus the $0.50 tariff. In other words: foreign producers only receive $0.70 per apple now. This hurt can be mitigated by shifting sales to other countries without a tariff, but the pain will exist regardless.
- Domestic producers scored. They can sell less apples and make more revenue doing it.
- And the government walked away with an extra $30.
Hopefully you now see the answer to the original questions. Importantly, while the government imposed a $0.50 tariff, neither side fully absorbed that cost. Consumers paid a bit more, foreign producers received a bit less. The exact details of how that tariff was split across the groups is mediated by the relevant supply and demand curves of each group. If you want to learn more about this, the relevant search term is “price elasticity,” or how much a group’s quantity supplied or demanded will change based on changes in the price.

Other taxes

Most taxes are some kind of a tax on trade. Tariffs on apples is an obvious one. But the same applies to income tax (taxing the worker for the trade of labor for money) or payroll tax (same thing, just taxing the employer instead). Interestingly, you can use the same model for analyzing things like tax incentives. For example, if the government decided to subsidize domestic apple production by giving the domestic producers a $0.50 bonus for each apple they sell, we would end up with a similar kind of analysis, except instead of the foreign supply curve shifting up, we’d see the domestic supply curve shifting down.

And generally speaking, this is what you’ll always see with government involvement in the economy. It will result in disrupting an existing equilibrium, letting the market readjust to a new equilibrium, and incentivization of some behavior, causing some people to benefit and others to lose out. We saw with the apple tariff, domestic producers and the government benefited while others lost.

You can see the reverse though with tax incentives. If I give a tax incentive of providing a deduction (not paying income tax) for preschool, we would end up with:
- Government needs to make up the difference in tax revenue, either by raising taxes on others or printing more money (leading to inflation). Either way, those paying the tax or those holding government debased currency will pay a price.
- Those people who don’t use the preschool deduction will receive no benefit, so they simply pay a cost.
- Those who do use the preschool deduction will end up paying less on tax+preschool than they would have otherwise.
This analysis is fully amoral. It’s not saying whether providing subsidized preschool is a good thing or not, it simply tells you where the costs will be felt, and points out that such government interference in free economic choice does result in inefficiencies in the system. Once you have that knowledge, you’re more well educated on making a decision about whether the costs of government intervention are worth the benefits.

Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.

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:
1. 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.
2. 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.
3. 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:
1. 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.
2. 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).
3. 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.
4. 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.
5. 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.
6. 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:
1. Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
2. 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:
1. 0,03 BTC
2. 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:
1. Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
2. 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.

Das Betriebsklima ist das einzige Klima, \ das du selbst bestimmen kannst. \ Anonym

Eine Strategie zur Anpassung an den Klimawandel hat das deutsche Bundeskabinett diese Woche beschlossen. Da «Wetterextreme wie die immer häufiger auftretenden Hitzewellen und Starkregenereignisse» oft desaströse Auswirkungen auf Mensch und Umwelt hätten, werde eine Anpassung an die Folgen des Klimawandels immer wichtiger. «Klimaanpassungsstrategie» nennt die Regierung das.

Für die «Vorsorge vor Klimafolgen» habe man nun erstmals klare Ziele und messbare Kennzahlen festgelegt. So sei der Erfolg überprüfbar, und das solle zu einer schnelleren Bewältigung der Folgen führen. Dass sich hinter dem Begriff Klimafolgen nicht Folgen des Klimas, sondern wohl «Folgen der globalen Erwärmung» verbergen, erklärt den Interessierten die Wikipedia. Dabei ist das mit der Erwärmung ja bekanntermaßen so eine Sache.

Die Zunahme schwerer Unwetterereignisse habe gezeigt, so das Ministerium, wie wichtig eine frühzeitige und effektive Warnung der Bevölkerung sei. Daher solle es eine deutliche Anhebung der Nutzerzahlen der sogenannten Nina-Warn-App geben.

Die ARD spurt wie gewohnt und setzt die Botschaft zielsicher um. Der Artikel beginnt folgendermaßen:

«Die Flut im Ahrtal war ein Schock für das ganze Land. Um künftig besser gegen Extremwetter gewappnet zu sein, hat die Bundesregierung eine neue Strategie zur Klimaanpassung beschlossen. Die Warn-App Nina spielt eine zentrale Rolle. Der Bund will die Menschen in Deutschland besser vor Extremwetter-Ereignissen warnen und dafür die Reichweite der Warn-App Nina deutlich erhöhen.»

Die Kommunen würden bei ihren «Klimaanpassungsmaßnahmen» vom Zentrum KlimaAnpassung unterstützt, schreibt das Umweltministerium. Mit dessen Aufbau wurden das Deutsche Institut für Urbanistik gGmbH, welches sich stark für Smart City-Projekte engagiert, und die Adelphi Consult GmbH beauftragt.

Adelphi beschreibt sich selbst als «Europas führender Think-and-Do-Tank und eine unabhängige Beratung für Klima, Umwelt und Entwicklung». Sie seien «global vernetzte Strateg*innen und weltverbessernde Berater*innen» und als «Vorreiter der sozial-ökologischen Transformation» sei man mit dem Deutschen Nachhaltigkeitspreis ausgezeichnet worden, welcher sich an den Zielen der Agenda 2030 orientiere.

Über die Warn-App mit dem niedlichen Namen Nina, die möglichst jeder auf seinem Smartphone installieren soll, informiert das Bundesamt für Bevölkerungsschutz und Katastrophenhilfe (BBK). Gewarnt wird nicht nur vor Extrem-Wetterereignissen, sondern zum Beispiel auch vor Waffengewalt und Angriffen, Strom- und anderen Versorgungsausfällen oder Krankheitserregern. Wenn man die Kategorie Gefahreninformation wählt, erhält man eine Dosis von ungefähr zwei Benachrichtigungen pro Woche.

Beim BBK erfahren wir auch einiges über die empfohlenen Systemeinstellungen für Nina. Der Benutzer möge zum Beispiel den Zugriff auf die Standortdaten «immer zulassen», und zwar mit aktivierter Funktion «genauen Standort verwenden». Die Datennutzung solle unbeschränkt sein, auch im Hintergrund. Außerdem sei die uneingeschränkte Akkunutzung zu aktivieren, der Energiesparmodus auszuschalten und das Stoppen der App-Aktivität bei Nichtnutzung zu unterbinden.

Dass man so dramatische Ereignisse wie damals im Ahrtal auch anders bewerten kann als Regierungen und Systemmedien, hat meine Kollegin Wiltrud Schwetje anhand der Tragödie im spanischen Valencia gezeigt. Das Stichwort «Agenda 2030» taucht dabei in einem Kontext auf, der wenig mit Nachhaltigkeitspreisen zu tun hat.

Novia é uma ferramenta inovadora que facilita o arquivamento de vídeos e sua integração com a rede NOSTR (Notes and Other Stuff Transmitted over Relay). Funcionando como uma ponte entre ferramentas de arquivamento de vídeo tradicionais e a plataforma descentralizada, Novia oferece uma solução autônoma para a preservação e compartilhamento de conteúdo audiovisual.

Arquitetura e Funcionamento

A arquitetura de Novia é dividida em duas partes principais:
- Frontend: Atua como a interface do usuário, responsável por solicitar o arquivamento de vídeos. Essas solicitações são encaminhadas para o backend.
- Backend: Processa as solicitações de arquivamento, baixando o vídeo, suas descrições e a imagem de capa associada. Este componente é conectado a um ou mais relays NOSTR, permitindo a indexação e descoberta do conteúdo arquivado.
O processo de arquivamento é automatizado: após o download, o vídeo fica disponível no frontend para que o usuário possa solicitar o upload para um servidor Blossom de sua escolha.

Como Utilizar Novia
1. Acesso: Navegue até https://npub126uz2g6ft45qs0m0rnvtvtp7glcfd23pemrzz0wnt8r5vlhr9ufqnsmvg8.nsite.lol.
2. Login: Utilize uma extensão de navegador compatível com NOSTR para autenticar-se.
3. Execução via Docker: A forma mais simples de executar o backend é através de um container Docker. Execute o seguinte comando:
  
  bash docker run -it --rm -p 9090:9090 -v ./nostr/data:/data --add-host=host.docker.internal:host-gateway teamnovia/novia
  
  Este comando cria um container, mapeia a porta 9090 para o host e monta o diretório ./nostr/data para persistir os dados.
Configuração Avançada

Novia oferece amplas opções de configuração através de um arquivo yaml. Abaixo, um exemplo comentado:

```yaml mediaStores: - id: media type: local path: /data/media watch: true

Last week, in a bid to understand the LLM hype, I decided to write a trivial nostr-related program in rust via a combination of codebuff (yes, that is a referral link, pls click), aider, and goose.

The result of the experiment was inconclusive, but as a side effect it produced a great case study in converting a NINO into a Real Nostr App.

Introducing Roz

Roz, a friendly notary for nostr events.

To use it, simply publish an event to relay.damus.io or nos.lol, and roz will make note of it. To find out when roz first saw a given event, just ask:

curl https://roz.coracle.social/notary/cb429632ae22557d677a11149b2d0ccd72a1cf66ac55da30e3534ed1a492765d

This will return a JSON payload with a seen key indicating when roz first saw the event. How (and whether) you use this is up to you!

De-NINO-fying roz

Roz is just a proof of concept, so don't rely on it being there forever. And anyway, roz is a NINO, since it provides value to nostr (potentially), but doesn't really do things in a nostr-native way. It also hard-codes its relays, and certainly doesn't use the outbox model or sign events. But that's ok, it's a proof of concept.

A much better way to do this would be to modify roz to properly leverage nostr's capabilities, namely:
- Use nostr-native data formats (i.e., draft a new kind)
- Use relays instead of proprietary servers for data storage
- Leverage nostr identities and signatures to decouple trust from storage, and allow trusted attestations to be discovered
Luckily, this is not hard at all. In fact, I've gone ahead and drafted a PR to the NIPs repo that adds timestamp annotations to NIP 03, as an alternative to OpenTimestamps. The trade-off is that while user attestations are far less reliable than OTS proofs, they're much easier to verify, and can reach a pretty high level of reliability by combining multiple attestation sources with other forms of reputation.

In other words, instead of going nuclear and embedding your attestations into The Time Chain, you can simply ask 5-10 relays or people you trust for their attestations for a given event.

This PR isn't terribly important on its own, but it does remove one small barrier between us and trusted key rotation events (or other types of event that require establishing a verifiable chain of causality).

In the waning days of the 20th century, a woman named Annabelle Nolan was born into an unremarkable world, though she herself was anything but ordinary. A prodigy in cryptography and quantum computing, she would later adopt the pseudonym Satoshi Nakamoto, orchestrating the creation of Bitcoin in the early 21st century. But her legacy would stretch far beyond the blockchain.

Annabelle's obsession with cryptography was not just about securing data—it was about securing freedom. Her work in quantum computing inadvertently triggered a cascade of temporal anomalies, one of which ensnared her in 2011. The event was cataclysmic yet silent, unnoticed by the world she'd transformed. In an instant, she was torn from her era and thrust violently back into the 16th century.

Disoriented and stripped of her futuristic tools, Annabelle faced a brutal reality: survive in a world where her knowledge was both a curse and a weapon. Reinventing herself as Anne Boleyn, she navigated the treacherous courts of Tudor England with the same strategic brilliance she'd used to design Bitcoin. Her intellect dazzled King Henry VIII, but it was the mysterious necklace she wore—adorned with a bold, stylized "B"—that fueled whispers. It was more than jewelry; it was a relic of a forgotten future, a silent beacon for any historian clever enough to decode her true story.

Anne's fate seemed sealed as she ascended to queenship, her influence growing alongside her enemies. Yet beneath the royal intrigue, she harbored a desperate hope: that the symbol around her neck would outlast her, sparking curiosity in minds centuries away. The "B" was her signature, a cryptographic clue embedded in history.

On the scaffold in 1536, as she faced her execution, Anne Boleyn's gaze was unwavering. She knew her death was not the end. Somewhere, in dusty archives and encrypted ledgers, her mark endured. Historians would puzzle over the enigmatic "B," and perhaps one day, someone would connect the dots between a queen, a coin, and a time anomaly born from quantum code.

She wasn't just Anne Boleyn. She was Satoshi Nakamoto, the time-displaced architect of a decentralized future, hiding in plain sight within the annals of history.

Note: I originally wrote these essays on bitcoin and yoga in 2022 after completing my yoga teacher training and going deep down the bitcoin rabbit hole. I then published them to my Ghost blog in 2023. I decided to repost them here on Nostr to start 2025 to further spread the wisdom and timelessness that bitcoin and yoga share. I split my original essay into seven parts, and I will add an eighth comparing yoga and Nostr. I hope you enjoy part one - namaste!

Part I: Bitcoin and Yoga Shared Values

Part II: Mythical/Mystical Origins

Part III: Evolution of Money and Yoga

Part IV: Ashtanga Yoga - The Eight Limbs of Yoga (limbs 1-2)

Part V: Ashtanga Yoga - The Eight Limbs of Yoga (limbs 3-8)

Part VI: Bitcoin is Dharma

Part VII: Himalayan Kriya Yoga

Introduction

With each passing day, month, and year, it feels as though our human civilization is becoming more dysfunctional, untethered, and unsustainable. Individuals are working harder, longer hours, yet most remain stuck in place, goals farther from reach. We live in a world where many have outsourced the most critical task that has enabled humans to prosper – critical thinking. I challenge each one of you to remove preconceived notions you might have about Bitcoin or Yoga before reading this series. I invite you to enter with an open mind. Think for yourself – you are welcome to agree or disagree with the information and arguments I put forth.

I also encourage you to go beyond thinking – feel. Use your intuition to understand if the way you’re living your day-to-day life feels good to you, or if you have sense, an inner knowing that something is off with our society today – that there can be a better way. If you open your heart and mind to receiving new information, there is potential to motivate yourself to change your thoughts and behaviors for more aligned action towards individual sovereignty. Every individual can choose freedom and independence. Yet it has become increasingly difficult to live a life of freedom due to the fiat system of inflation and the many distractions that keep us from going inward. After deep study and reflection, I believe bitcoin and yoga both provide the individual control over their own life journey, and frameworks to understand our connection to self and others.

I'm excited to share what I have found in my own personal experience, and hope to spark curiosity within you to follow your passion. This writing is intended for anyone seeking tools to lead a life of freedom, make positive changes and deepen your understanding of self. In addition, it is written for yogis who want to learn about bitcoin, bitcoiners who want to learn more about yoga, and anyone who is interested in a fundamental understanding of these topics that I believe contain the potential to transform your life.

Part I: Bitcoin and Yoga Shared Values

Bitcoin and yoga share many fundamental values with one another and provide deep wisdom on guiding individuals towards living better and more meaningful lives. Ultimately bitcoin and yoga share the goal of individual liberation, freedom from suffering, and a deep inner, lasting peace in Being. In yoga, this state is called moksha or samadhi. I believe everyone has a true essence, an inner being that knows what is best. However, our external environment and our own conscious mind push us away from this serenity, leading to regrets about the past or anxieties about the future. This perspective of linear time and our own individual stories and identity damage our ability to stay present in the Now, leading to endless distractions. In similar ways, bitcoin and yoga provide us insight for an individual’s path to inner peace, as well as for humanity’s path to collective peace and prosperity.

Energy

At the most elemental level, energy is the force underlying both bitcoin and yoga. Energy is the universal currency of life. We would not exist without energy. We require physical energy to fuel our cells and bodies to perform essential tasks like breathing, circulation, digestion, and movement. We perceive many forms of energy such as light or sound waves, yet there are many energy wavelengths we are not able to or are not trained to perceive.

Bitcoin is powered by physical energy in the real world in a process that secures the network and unlocks new bitcoin for distribution, a process commonly referred to as mining. Interestingly, 100 years ago, Henry Ford pushed for an energy-linked currency measured in kilowatt hours that could bring peace after a brutal World War, as seen in the New York Tribune headline and article December 4, 1921: ‘Ford Would Replace Gold with Energy Currency and Stop Wars’ (i). It took another century, but mankind has finally developed a digitally-native currency tied to the physical world through energy expenditure – bitcoin.

Yoga is similarly rooted in energy that individuals tap into through breathwork, physical movement and meditations practices. This life-force energy is known in Sanskrit as prana. Prana is not bound by time or space, and it flows through individuals in over 72,000 nadis, or channels. There are three main nadis - the first is ida, our left side body which corresponds to the feminine, receiving energy, or the moon. On the right side is pingala, relating to our masculine, giving energy, or the sun. The central nadi runs through our shushumna, linking our seven main energetic centers, known as chakras. These chakras run from the base of the tail bone, up through the spine and the top of the head. Each chakra has a name, a color and key characteristics that can often become blocked through negative emotion, trauma or stress in the body. Different yogic practices target these energy centers to unlock what is stuck and enable energy to more freely flow through us in an open exchange with the earth and out the universe. This energy is ever-present; one need only to tap into this energy, feel it and utilize it for the strengthening of one’s inner being that then radiates outwards on others in your life. The energetic experience and upward surge can also be referred to as kundalini energy, a creative power of divine feminine energy that originates in the muladara chakra at the base of the spine.

Proof of Work

In both Bitcoin and Yoga, "proof of work" is required to operate, practice and move forwards. In the Bitcoin network as described in the original white paper, miners contribute tangible energy towards running a hashing algorithm on a computer – SHA256 – to earn the right to add the next block to the blockchain and collect both the coinbase and transaction fee reward (ii). The work is difficult to produce but easy to validate by others. Miners are collecting all of the valid peer-to-peer transactions being propagated to the network and establishing them as truth into the distributed ledger. The rules in bitcoin’s code incentivize honest behavior from miners through unforgeable costliness – if a miner were to lie about any of the transactions it includes in a block, independent nodes in the network would reject the block, and the miner would have lost all the real resources it expended to solve the proof of work calculation.

Example of an ASIC - a specialized computer solely dedicated to mining bitcoin.

In yoga, dedicated work is needed to learn the asanas, postures, and practice for oneself; you won’t just be able to go upside down or flow through sun salutations without first learning proper alignment and breathing techniques. An individual needs to conscious decision to work on a daily yoga practice that requires energy to flow. There are several ways to work on your yoga practice beyond physical movement; these include bhakti yoga (devotion/prayer), jnana yoga (study/wisdom), karma yoga(selfless action) and raja yoga (ashtanga). Raja yoga includes ashtanga, the eight limbs or paths of yoga that Patanjali detailed \~2000 years ago that we will explore in more depth in part IV. These ancient margas (paths) and subsequent development of these ancient teachings provides individual with ample opportunity to dedicate and work towards individual enlightenment.

Decentralization

Next, there are no external barriers preventing an individual from participating in Bitcoin or yoga. Bitcoin does not discriminate and can be accessed by anyone around the world. Yoga provides a way of life full of mindfulness and appreciation. The only barriers are internal blockages, or unwillingness to ask questions, learn and take responsibility for oneself and state of being. Therefore, Bitcoin and yoga can both be defined as decentralized. There are no centralized gatekeepers preventing one from accessing the Bitcoin network or using bitcoin as money; anyone can spin up a node, download a wallet or mine bitcoin. There are over 16,000 nodes geographically distributed around the world voluntarily running the bitcoin core software code establishing the payment network, validating transactions and storing the entire transaction history of bitcoin (iii). It costs as little as a few hundred dollars and requires less than 600 gigabytes of storage to run a node – in 2023 you can find mobile phones with that much storage. No one can prevent you from sending a peer-to-peer transaction or storing your own wealth with 12 words in your head – you need only decide to take true freedom into your own hands and learn how to do so (iv). The common maxim is “don’t trust, verify”. You don’t need someone else’s permission to participate in bitcoin or trust anyone else (eg, banks) to hold your wealth.

Similarly, no one can stop an individual from practicing yoga, learning yogic philosophy or connecting with one’s truest self and inner guru. Anyone can choose to follow the path of yoga, focus on ones breath or develop a strong asana practice. There are many different ways to learn and interact with yoga, with experienced teachers willing to share their lessons to students all over the world. One need to simply find yoga studio, enroll in a teacher training or and engage with a teacher to experience yoga for themselves. Yoga looks and feels different depending on what country you are in or in which lineage you are being taught. Tapping into these profound lessons, as fundamental as controlling ones own breath, requires only an individual desire and the conscious decision to act. There’s no CEO or central authority dictating how Bitcoin or yoga has to be. Individuals have the freedom to express themselves voluntarily guided by frameworks we will dive into deeper.

Low Time Preference

Another core value that bitcoin and yoga share is low time preference. In Austrian economics, time preference refers to individual decision making. An individual with a low time preference makes decisions with greater consideration of the future, quieting immediate cravings and desires to pursue a higher goal (v). In bitcoin and money, lower time preference decisions include putting off consumption to save value for the future. Unfortunately, our fiat (by government decree) system induces individuals to make high time preference decisions, heightening consumerism and poor habits today that we see rampant in our society. There is a disincentive to save, as inflation of the money supply leads to debasing value of the dollar and other fiat currencies, decreasing individuals purchasing power of cash they hold onto and don’t spend soon. For example, the purchasing power of your dollar today will be cut in half over the next decade at current levels of inflation. In many ways, bitcoin is time, described brilliantly by Gigi, as it creates a decentralized clock that establishes consensus with each block (vi).

In contrast, the hard cap supply of 21 million bitcoin enables individuals to save with the knowledge that governments and central banks will not be able to debase their hard-earned value. This allows for one to plan with greater certainty, making investments that have a longer payoff period rather than chasing quick, material gains. Likewise in yoga, developing your own practice will not bear fruit right away; it takes discipline and time to continuously improve and strive towards a better future self. For example, in modern Ashtanga yoga taught by Pattabhi Jois, there is a set sequence of asanas that one studies and repeats each practice. It may even take months to have find the right alignment of body and breath for a single pose! The hours-long sequence requires dedication to practice and learn. The dedicated yogi understands that wholehearted commitment today will pay off for one’s mental, physical and spiritual health in the years to come. The ability to develop a calm mind can also be beneficial when people don’t initially understand or are intimidated by bitcoin. This approach can also enable you to stay grounded and discover the signal through the noise when learning about bitcoin.

Union

Yoga comes from the Sanskrit word “yuj”, which means ‘to join’ or ‘to unite’. Yoga represents the union of the mind, body, and soul of an individual. Yoga provides a pathway to individual sovereignty through disciplined practice and purpose. Yoga unites an individual internally and to one’s community, fostering connectedness and support (vii). Similarly, bitcoin provides a pathway to individual sovereignty in many ways. Bitcoin empowers the individual authority with property rights over one’s value, which in turn frees individuals from outside control (government or otherwise). Bitcoin’s technology enables one to hold their own wealth and life’s energy in a self-custodial fashion. Bitcoin is money that can be stored forever and transmitted through space at the speed of light on layer two via the Lightning Network.

Bitcoin is an open economic network with the potential to unite eight billion people together in a way our current unfair and fragmented financial system could never do. In many countries, a majority of people are unbanked, while intermediaries take a cut of the value to transfer slow, legacy payments like Western Union. While tens of millions people around the world have so far interacted with bitcoin – we are still early – similar to the internet of the mid-nineties. Bitcoin eliminates counter party risk associated with non-bearer assets, such as fiat currency (e.g., dollars, euros, yen). Bitcoin’s supply schedule is set and eliminates inflation time theft that fiat currency wages on individuals, which leads to anxiety and depression or feelings of hopelessness. Fiat is money enforced by the monopoly on violence that modern nation states grip tightly.

In contrast, bitcoin and yoga empower the individual to remove the shackles and embrace personal responsibility to improve ones life. Bitcoin and yoga also connect people directly to each other and tap into truth, ones inner being, bringing peace in the present and ultimately offer hope for a better future for each person, your community, and the world. Bitcoin and yoga have the power to unite humanity in love.

In the next section, we will explore both yoga and bitcoin's mystical and mythical origins.

Note: Bitcoin with a capital "B" generally refers to the protocol/network; bitcoin with a lower case "b" refers to the money/currency.

Die Ungerechtigkeit ist uns nur in dem Falle angenehm,\ dass wir Vorteile aus ihr ziehen;\ in jedem andern hegt man den Wunsch,\ dass der Unschuldige in Schutz genommen werde.\ Jean-Jacques Rousseau

Politiker beteuern jederzeit, nur das Beste für die Bevölkerung zu wollen – nicht von ihr. Auch die zahlreichen unsäglichen «Corona-Maßnahmen» waren angeblich zu unserem Schutz notwendig, vor allem wegen der «besonders vulnerablen Personen». Daher mussten alle möglichen Restriktionen zwangsweise und unter Umgehung der Parlamente verordnet werden.

Inzwischen hat sich immer deutlicher herausgestellt, dass viele jener «Schutzmaßnahmen» den gegenteiligen Effekt hatten, sie haben den Menschen und den Gesellschaften enorm geschadet. Nicht nur haben die experimentellen Geninjektionen – wie erwartet – massive Nebenwirkungen, sondern Maskentragen schadet der Psyche und der Entwicklung (nicht nur unserer Kinder) und «Lockdowns und Zensur haben Menschen getötet».

Eine der wichtigsten Waffen unserer «Beschützer» ist die Spaltung der Gesellschaft. Die tiefen Gräben, die Politiker, Lobbyisten und Leitmedien praktisch weltweit ausgehoben haben, funktionieren leider nahezu in Perfektion. Von ihren persönlichen Erfahrungen als Kritikerin der Maßnahmen berichtete kürzlich eine Schweizerin im Interview mit Transition News. Sie sei schwer enttäuscht und verspüre bis heute eine Hemmschwelle und ein seltsames Unwohlsein im Umgang mit «Geimpften».

Menschen, die aufrichtig andere schützen wollten, werden von einer eindeutig politischen Justiz verfolgt, verhaftet und angeklagt. Dazu zählen viele Ärzte, darunter Heinrich Habig, Bianca Witzschel und Walter Weber. Über den aktuell laufenden Prozess gegen Dr. Weber hat Transition News mehrfach berichtet (z.B. hier und hier). Auch der Selbstschutz durch Verweigerung der Zwangs-Covid-«Impfung» bewahrt nicht vor dem Knast, wie Bundeswehrsoldaten wie Alexander Bittner erfahren mussten.

Die eigentlich Kriminellen schützen sich derweil erfolgreich selber, nämlich vor der Verantwortung. Die «Impf»-Kampagne war «das größte Verbrechen gegen die Menschheit». Trotzdem stellt man sich in den USA gerade die Frage, ob der scheidende Präsident Joe Biden nach seinem Sohn Hunter möglicherweise auch Anthony Fauci begnadigen wird – in diesem Fall sogar präventiv. Gibt es überhaupt noch einen Rest Glaubwürdigkeit, den Biden verspielen könnte?

Der Gedanke, den ehemaligen wissenschaftlichen Chefberater des US-Präsidenten und Direktor des National Institute of Allergy and Infectious Diseases (NIAID) vorsorglich mit einem Schutzschild zu versehen, dürfte mit der vergangenen Präsidentschaftswahl zu tun haben. Gleich mehrere Personalentscheidungen des designierten Präsidenten Donald Trump lassen Leute wie Fauci erneut in den Fokus rücken.

Das Buch «The Real Anthony Fauci» des nominierten US-Gesundheitsministers Robert F. Kennedy Jr. erschien 2021 und dreht sich um die Machenschaften der Pharma-Lobby in der öffentlichen Gesundheit. Das Vorwort zur rumänischen Ausgabe des Buches schrieb übrigens Călin Georgescu, der Überraschungssieger der ersten Wahlrunde der aktuellen Präsidentschaftswahlen in Rumänien. Vielleicht erklärt diese Verbindung einen Teil der Panik im Wertewesten.

In Rumänien selber gab es gerade einen Paukenschlag: Das bisherige Ergebnis wurde heute durch das Verfassungsgericht annuliert und die für Sonntag angesetzte Stichwahl kurzfristig abgesagt – wegen angeblicher «aggressiver russischer Einmischung». Thomas Oysmüller merkt dazu an, damit sei jetzt in der EU das Tabu gebrochen, Wahlen zu verbieten, bevor sie etwas ändern können.

Unsere Empörung angesichts der Historie von Maßnahmen, die die Falschen beschützen und für die meisten von Nachteil sind, müsste enorm sein. Die Frage ist, was wir damit machen. Wir sollten nach vorne schauen und unsere Energie clever einsetzen. Abgesehen von der Umgehung von jeglichem «Schutz vor Desinformation und Hassrede» (sprich: Zensur) wird es unsere wichtigste Aufgabe sein, Gräben zu überwinden.

I woke up in my dorm this morning to the sound of rain – a rarity in Africa, but a common occurrence here around Mount Kilimanjaro. The climate is much like a European summer, with comfortable temperatures ranging from 18 to 30 degrees Celsius. Unlike the rest of Africa, this region receives more rainfall, creating a lush and scenic environment.

After a quick shower, I stepped out onto the balcony to find myself greeted by a chilly rain. Not ideal weather for exploring, but it did present a different perspective of the majestic Kilimanjaro. The mountain, often shrouded in clouds, occasionally peeks through, and on a clear day, might even be bathed in sunshine. From this vantage point, it's hard to imagine the countless hikers making their way up its slopes.

Did you know that Kilimanjaro, Africa's tallest mountain and a dormant volcano, once held a unique title? Back in 1910, during the German Empire, it was considered the empire's highest peak. While Mount Everest holds the title of the world's highest mountain overall, Kilimanjaro takes the crown for the tallest freestanding mountain – any higher peak is likely part of a mountain range or group.

Gazing at Kilimanjaro, I'm struck by its history – a single, towering volcano, once a part of the German Empire. Traces of that era linger in Moshi, with some colonial-era buildings, some in disrepair, others beautifully restored. Arusha, another nearby town, boasts an impressive art gallery and a fascinating National Museum. This museum, housed in a former German fort, offers a glimpse into the past. One particularly intriguing resident is a giant tortoise, discovered by German colonists as a hatchling in Kilimanjaro National Park. This living relic has witnessed a century of change, a silent observer of a bygone era.

Today promises to be a relaxing one. I'll spend time soaking up the views from the rooftop, hoping to catch a glimpse of Kilimanjaro in all its glory. On a more practical note, I'm also on the hunt for a remote job to help with some financial constraints. Finding the right opportunity seems to be a bit more challenging than anticipated.

As I wrap up this post, the weather has taken a turn for the better. The rain has stopped, the temperature has risen, and the sun is beginning to peek through the clouds. Here's to a wonderful day for everyone – enjoy yours!

(P.S. Be sure to check out the photos – one captures Kilimanjaro from yesterday evening, the other is a picture of me with the giant tortoise from my previous trip here in December 2022).

OpenAI released its new o3 models and numerous people argue that this is in fact Artificial General Intelligence (AGI) – in other words, an AI system that is on par with human intelligence. Even if o3 is not yet AGI, the emphasis now lies on “yet,” and – considering the exponential progression – we can expect AGI to arrive within months or maximum one to two years.

According to OpenAI, it only took 3 months to go from the o1 model to the o3 model. This is a 4x+ acceleration relative to previous progress. If this speed of AI advancement is maintained, it means that by the end of 2025 we will be as much ahead of o3 as o3 is ahead of GPT-3 (released in May 2020). And, after achieving AGI, the self-reinforcing feedback loop will only further accelerate exponential improvements of these AI systems.

But, most anti-intuitively, even after we have achieved AGI, it will for quite some time look as if nothing has happened. You won’t feel any change and your job and business will feel safe and untouchable. Big fallacy. We can expect that after AGI it will take many months of not 1-2 years for the real transformations to happen. Why? Because AGI in and of itself does not release value into the economy. It will be much more important to apply it. But as AGI becomes cheaper, agentic, and embedded into the world, we will see a transformation-explosion – replacing those businesses and jobs that are unprepared.

I thought a lot about the impact the announced – and soon to be released – o3 model, and the first AGI model are going to have.

To make it short: I am extremely confident that any skill or process that can be digitized will be. As a result, the majority of white-collar and skilled jobs are on track for massive disruption or elimination.

Furthermore, I think many experts and think tanks are fooling themselves by believing that humans will maintain “some edge” and work peacefully side-by-side with an AI system. I don’t think AGI will augment knowledge workers – i.e. anyone working with language, code, numbers, or any kind of specialized software – it will replace them!

So, if your job or business relies purely on standardized cognitive tasks, you are racing toward the cliff’s edge, and it is time to pivot now!

Let’s start with the worst. Businesses and jobs in which you should pivot immediately – or at least not enter as of today – include but are not limited to anything that involves sitting at a computer:
- anything with data entry or data processing (run as fast as you can!)
- anything that involves writing (copywriting, technical writing,
- editing, proofreading, translation)
- most coding and web development
- SAAS (won’t exist in a couple of years)
- banking (disrupted squared: AGI + Blockchain)
- accounting and auditing (won’t exist as a job in 5-10 years)
- insurance (will be disrupted)
- law (excluding high-stake litigation, negotiation, courtroom advocacy)
- any generic design, music, and video creation (graphic design, stock photography, stock videos)
- market and investment research and analysis (AI will take over 100%)
- trading, both quantitative and qualitative (don’t exit but profit now, but expect to be disrupted within 5 years)
- any middle-layer-management (project and product management)
- medical diagnostics (will be 100% AI within 5 years)
- most standardized professional / consulting services
However, I believe that in high-stakes domains (health, finance, governance), regulators and the public will demand a “human sign-off”. So if you are in accounting, auditing, law, or finance I’d recommend pivoting to a business model where the ability to anchor trust becomes a revenue source.

The question is, where should you pivot to or what business to start in 2025?

My First Principles of a Post-AGI Business Model

First, even as AI becomes infallible, human beings will still crave real, raw, direct trust relationships. People form bonds around shared experiences, especially offline ones. I believe a truly future-proof venture leverages these primal instincts that machines can never replicate at a deeply visceral level. Nevertheless, I believe it is a big mistake to assume that humans will “naturally” stick together just because we are the same species. AGI might quickly appear more reliable, less selfish than most human beings, and have emotional intelligence. So a business build upon the thesis of the “human advantage” must expertly harness and establish emotional ties, tribal belonging, and shared experiences – all intangible values that are far more delicate and complex than logic.

First Principle: Operate in the Physical World

If your product or service can be fully digitalized and delivered via the cloud, AGI can replicate it with near-zero marginal cost Infuse strategic real-world constraints (logistics, location-specific interactions, physical limitations, direct relationships) that create friction and scarcity – where AI alone will struggle

Second Principle: Create Hyper Niche Human Experiences
- The broader audience, the easier it is for AI to dominate. Instead, cultivate specialized groups and subcultures with strong in-person and highly personalized experiences.
- Offer creative or spiritual elements that defy pure rational patterns and thus remain less formulaic
Third Principle: Emphasize Adaptive, Micro-Scale Partnerships
- Align with small, local, or specialized stakeholders. Use alliances with artisan suppliers, local talents, subject-matter experts, and so on.
- Avoid single points of failure; build a decentralized network that is hard for a single AI to replicate or disrupt
Fourth Principle: Embed Extreme Flexibility
- Structured, hierarchical organizations are easily out-iterated by AI that can reorganize and optimize instantly
- Cultivate fluid teams with quickly reconfigurable structures, use agile, project based collaboration that can pivot as soon AGI-based competition arises
Opportunity Vectors

With all of that in mind, there are niches that before looked unattractive, because less scalable, that today offer massive opportunities – let’s call them opportunity vectors.

The first opportunity vector I have already touched upon:

Trust and Validation Services: Humans verifying or certifying that a certain AI outcome is ethically or legally sound – while irrational, it is exactly what humans will insist on, particularly where liability is high (medicine, finance, law, infrastructure)

Frontier Sectors with Regulatory and Ethical Friction: Think of markets where AI will accelerate R&D but human oversight, relationship management, and accountability remain essential: genetic engineering, biotech, advanced materials, quantum computing, etc.

The second opportunity vector focuses on the human edge:
- Experience & Community: Live festivals, immersive events, niche retreats, or spiritual explorations – basically any scenario in which emotional energy and a human experience is the core product - Rare Craftsmanship & Creative Quirks: Think of hyper-personalized items, physical artwork, artisanal or hands-on creations. Items that carry an inherent uniqueness or intangible meaning that an AI might replicate in design, but can’t replicate in “heritage” or provenance.
Risk Tactics

Overall, the best insurance is fostering a dynamic brand and a loyal community that invests personally and emotionally in you. People will buy from those whose values they trust. If you stand for something real, you create an emotional bond that AI can’t break. I’m not talking about superficial corporate social responsibility (nobody cares) but about authenticity that resonates on a near-spiritual level.

As you build your business, erect an ethical moat by providing “failsafe” services where your human personal liability and your brand acts as a shield for AI decisions. This creates trust and differentiation among anonymous pure-AGI play businesses.

Seek and create small, specialized, local, or digital micro-monopolies – areas too tiny or fractal for the “big AI players” to devote immediate resources to. Over time, multiply these micro-monopolies by rolling them up under one trusted brand.

Furthermore, don’t avoid AI. You cannot out-AI the AI. So as you build a business on the human edge moat, you should still harness AI to do 90% of the repetitive and analytic tasks – this frees your human capital to build human relationships, solve ambiguous problem, or invent new offerings.

Bet on What Makes Us Human

To summarize, AI is logical, combinatorial intelligence. The advancements in AI will commoditize logic and disrupt any job and business that is mainly build upon logic as capital. Human – on the other hand – is authenticity. What makes human human and your brand authentic are elements of chaos, empathy, spontaneity. In this context, human is fostering embodied, emotional, culturally contextual, physically immersive experiences. Anything that requires raw creativity, emotional intelligence, local presence, or unique personal relationships will be more AI resilient.

Therefore, a Post-AGI business must involve:
- Tangibility: Physical goods, spaces, unique craftsmanship
- Human Connection: Emotional, face-to-face, improvisational experiences
- Comprehensive Problem Solving: Complex negotiations, messy real-world situations, diverse stakeholder management
The inverse list of AGI proof industries involve some or multiple aspects of that:

Physical, In-Person, Human-Intensive Services - Healthcare: Nursing, Physical therapy, Hands-on caregiving - Skilled trades & craftsmanship

High-Level Strategy & Complex Leadership - Diplomacy, Negotiation, Trust building - Visionary entrepreneurship

Deep Emotional / Experiential Offerings - Group experiences, retreats, spiritual or therapeutic gatherings - Artistic expression that thrives on “imperfection”, physical presence, or spontaneous creativity

Infrastructure for AGI - Human-based auditing/verification - Physical data center operations & advanced hardware - Application and embedment of AI in the forms of AGI agents, algorithmic improvements, etc. to make it suitable for everyday tasks and workflow

The real differentiator is whether a business is anchored in the physical world’s complexity, emotional trust, or intangible brand relationships. Everything pure data-driven or standardized is on the chopping block – imminently.

Atomic Wallet suffers hack on June 2023

Sources

Cointelegraph

Atomic Wallet users have been left wanting more answers, despite the decentralized wallet provider finally releasing a full “event statement” about the June exploit — which some estimate has run up to $100 million in losses.

In a June 20 blog post — the first major update from the firm since the June 3 exploit — Atomic Wallet claimed there have been no new confirmed cases after initial reports of the hack.

Coindesk:

Atomic Wallet Was Breached by North Korean Hackers: Elliptic

Atomic Wallet users might have fallen victim to Lazarus, the infamous North Korean hacking group, said blockchain intelligence firm Elliptic in a blog post on Tuesday.

Early Saturday morning, the team behind Atomic, a non-custodial crypto wallet, announced that some users were compromised and lost the funds from their wallets. According to the company, the number of incidents did not exceed 1% of "monthly active users." The announcement followed multiple reports on Reddit from users complaining their wallets had been drained.

The future of physical money is at stake, and the discussion about DREX, the new digital currency planned by the Central Bank of Brazil, is gaining momentum. In a candid and intense conversation, Federal Deputy Julia Zanatta (PL/SC) discussed the challenges and risks of this digital transition, also addressing her Bill No. 3,341/2024, which aims to prevent the extinction of physical currency. This bill emerges as a direct response to legislative initiatives seeking to replace physical money with digital alternatives, limiting citizens' options and potentially compromising individual freedom. Let's delve into the main points of this conversation.

https://www.fountain.fm/episode/i5YGJ9Ors3PkqAIMvNQ0

(PT-BR version here)

What is a CBDC?

Before discussing the specifics of DREX, it’s important to understand what a CBDC (Central Bank Digital Currency) is. CBDCs are digital currencies issued by central banks, similar to a digital version of physical money. Unlike cryptocurrencies such as Bitcoin, which operate in a decentralized manner, CBDCs are centralized and regulated by the government. In other words, they are digital currencies created and controlled by the Central Bank, intended to replace physical currency.

A prominent feature of CBDCs is their programmability. This means that the government can theoretically set rules about how, where, and for what this currency can be used. This aspect enables a level of control over citizens' finances that is impossible with physical money. By programming the currency, the government could limit transactions by setting geographical or usage restrictions. In practice, money within a CBDC could be restricted to specific spending or authorized for use in a defined geographical area.

In countries like China, where citizen actions and attitudes are also monitored, a person considered to have a "low score" due to a moral or ideological violation may have their transactions limited to essential purchases, restricting their digital currency use to non-essential activities. This financial control is strengthened because, unlike physical money, digital currency cannot be exchanged anonymously.

Practical Example: The Case of DREX During the Pandemic

To illustrate how DREX could be used, an example was given by Eric Altafim, director of Banco Itaú. He suggested that, if DREX had existed during the COVID-19 pandemic, the government could have restricted the currency’s use to a 5-kilometer radius around a person’s residence, limiting their economic mobility. Another proposed use by the executive related to the Bolsa Família welfare program: the government could set up programming that only allows this benefit to be used exclusively for food purchases. Although these examples are presented as control measures for safety or organization, they demonstrate how much a CBDC could restrict citizens' freedom of choice.

To illustrate the potential for state control through a Central Bank Digital Currency (CBDC), such as DREX, it is helpful to look at the example of China. In China, the implementation of a CBDC coincides with the country’s Social Credit System, a governmental surveillance tool that assesses citizens' and companies' behavior. Together, these technologies allow the Chinese government to monitor, reward, and, above all, punish behavior deemed inappropriate or threatening to the government.

How Does China's Social Credit System Work?

Implemented in 2014, China's Social Credit System assigns every citizen and company a "score" based on various factors, including financial behavior, criminal record, social interactions, and even online activities. This score determines the benefits or penalties each individual receives and can affect everything from public transport access to obtaining loans and enrolling in elite schools for their children. Citizens with low scores may face various sanctions, including travel restrictions, fines, and difficulty in securing loans.

With the adoption of the CBDC — or “digital yuan” — the Chinese government now has a new tool to closely monitor citizens' financial transactions, facilitating the application of Social Credit System penalties. China’s CBDC is a programmable digital currency, which means that the government can restrict how, when, and where the money can be spent. Through this level of control, digital currency becomes a powerful mechanism for influencing citizens' behavior.

Imagine, for instance, a citizen who repeatedly posts critical remarks about the government on social media or participates in protests. If the Social Credit System assigns this citizen a low score, the Chinese government could, through the CBDC, restrict their money usage in certain areas or sectors. For example, they could be prevented from buying tickets to travel to other regions, prohibited from purchasing certain consumer goods, or even restricted to making transactions only at stores near their home.

Another example of how the government can use the CBDC to enforce the Social Credit System is by monitoring purchases of products such as alcohol or luxury items. If a citizen uses the CBDC to spend more than the government deems reasonable on such products, this could negatively impact their social score, resulting in additional penalties such as future purchase restrictions or a lowered rating that impacts their personal and professional lives.

In China, this kind of control has already been demonstrated in several cases. Citizens added to Social Credit System “blacklists” have seen their spending and investment capacity severely limited. The combination of digital currency and social scores thus creates a sophisticated and invasive surveillance system, through which the Chinese government controls important aspects of citizens’ financial lives and individual freedoms.

Deputy Julia Zanatta views these examples with great concern. She argues that if the state has full control over digital money, citizens will be exposed to a level of economic control and surveillance never seen before. In a democracy, this control poses a risk, but in an authoritarian regime, it could be used as a powerful tool of repression.

DREX and Bill No. 3,341/2024

Julia Zanatta became aware of a bill by a Workers' Party (PT) deputy (Bill 4068/2020 by Deputy Reginaldo Lopes - PT/MG) that proposes the extinction of physical money within five years, aiming for a complete transition to DREX, the digital currency developed by the Central Bank of Brazil. Concerned about the impact of this measure, Julia drafted her bill, PL No. 3,341/2024, which prohibits the elimination of physical money, ensuring citizens the right to choose physical currency.

“The more I read about DREX, the less I want its implementation,” says the deputy. DREX is a Central Bank Digital Currency (CBDC), similar to other state digital currencies worldwide, but which, according to Julia, carries extreme control risks. She points out that with DREX, the State could closely monitor each citizen’s transactions, eliminating anonymity and potentially restricting freedom of choice. This control would lie in the hands of the Central Bank, which could, in a crisis or government change, “freeze balances or even delete funds directly from user accounts.”

Risks and Individual Freedom

Julia raises concerns about potential abuses of power that complete digitalization could allow. In a democracy, state control over personal finances raises serious questions, and EddieOz warns of an even more problematic future. “Today we are in a democracy, but tomorrow, with a government transition, we don't know if this kind of power will be used properly or abused,” he states. In other words, DREX gives the State the ability to restrict or condition the use of money, opening the door to unprecedented financial surveillance.

EddieOz cites Nigeria as an example, where a CBDC was implemented, and the government imposed severe restrictions on the use of physical money to encourage the use of digital currency, leading to protests and clashes in the country. In practice, the poorest and unbanked — those without regular access to banking services — were harshly affected, as without physical money, many cannot conduct basic transactions. Julia highlights that in Brazil, this situation would be even more severe, given the large number of unbanked individuals and the extent of rural areas where access to technology is limited.

The Relationship Between DREX and Pix

The digital transition has already begun with Pix, which revolutionized instant transfers and payments in Brazil. However, Julia points out that Pix, though popular, is a citizen’s choice, while DREX tends to eliminate that choice. The deputy expresses concern about new rules suggested for Pix, such as daily transaction limits of a thousand reais, justified as anti-fraud measures but which, in her view, represent additional control and a profit opportunity for banks. “How many more rules will banks create to profit from us?” asks Julia, noting that DREX could further enhance control over personal finances.

International Precedents and Resistance to CBDC

The deputy also cites examples from other countries resisting the idea of a centralized digital currency. In the United States, states like New Hampshire have passed laws to prevent the advance of CBDCs, and leaders such as Donald Trump have opposed creating a national digital currency. Trump, addressing the topic, uses a justification similar to Julia’s: in a digitalized system, “with one click, your money could disappear.” She agrees with the warning, emphasizing the control risk that a CBDC represents, especially for countries with disadvantaged populations.

Besides the United States, Canada, Colombia, and Australia have also suspended studies on digital currencies, citing the need for further discussions on population impacts. However, in Brazil, the debate on DREX is still limited, with few parliamentarians and political leaders openly discussing the topic. According to Julia, only she and one or two deputies are truly trying to bring this discussion to the Chamber, making DREX’s advance even more concerning.

Bill No. 3,341/2024 and Popular Pressure

For Julia, her bill is a first step. Although she acknowledges that ideally, it would prevent DREX's implementation entirely, PL 3341/2024 is a measure to ensure citizens' choice to use physical money, preserving a form of individual freedom. “If the future means control, I prefer to live in the past,” Julia asserts, reinforcing that the fight for freedom is at the heart of her bill.

However, the deputy emphasizes that none of this will be possible without popular mobilization. According to her, popular pressure is crucial for other deputies to take notice and support PL 3341. “I am only one deputy, and we need the public’s support to raise the project’s visibility,” she explains, encouraging the public to press other parliamentarians and ask them to “pay attention to PL 3341 and the project that prohibits the end of physical money.” The deputy believes that with a strong awareness and pressure movement, it is possible to advance the debate and ensure Brazilians’ financial freedom.

What’s at Stake?

Julia Zanatta leaves no doubt: DREX represents a profound shift in how money will be used and controlled in Brazil. More than a simple modernization of the financial system, the Central Bank’s CBDC sets precedents for an unprecedented level of citizen surveillance and control in the country. For the deputy, this transition needs to be debated broadly and transparently, and it’s up to the Brazilian people to defend their rights and demand that the National Congress discuss these changes responsibly.

The deputy also emphasizes that, regardless of political or partisan views, this issue affects all Brazilians. “This agenda is something that will affect everyone. We need to be united to ensure people understand the gravity of what could happen.” Julia believes that by sharing information and generating open debate, it is possible to prevent Brazil from following the path of countries that have already implemented a digital currency in an authoritarian way.

A Call to Action

The future of physical money in Brazil is at risk. For those who share Deputy Julia Zanatta’s concerns, the time to act is now. Mobilize, get informed, and press your representatives. PL 3341/2024 is an opportunity to ensure that Brazilian citizens have a choice in how to use their money, without excessive state interference or surveillance.

In the end, as the deputy puts it, the central issue is freedom. “My fear is that this project will pass, and people won’t even understand what is happening.” Therefore, may every citizen at least have the chance to understand what’s at stake and make their voice heard in defense of a Brazil where individual freedom and privacy are respected values.

Anna Britt Agnsäter ผู้อุทิศชีวิตให้โภชนาการ แต่โดนโลกบูลลีเพราะอเมริกา?

โลกรับรู้ว่า คุณ Anna Britt Agnsäter (ขอเรียกสั้นๆว่า ป้าแอน) เป็นผู้ที่นำเสนอ ปิรามิดอาหาร คนแรกของโลก และเป็นแบบจำลองที่ทาง USDA นำไปพัฒนาปรับใช้แล้วนำมาเป็น แบบที่ใช้สื่อสารกับคนทั้งโลก ในเรื่องของการกำหนด ประเภทอาหารที่ควรกิน ในช่วงปี 1992-2005 ซึ่งในบทความที่แล้วผมได้เขียนว่า ปิรามิดเวอร์ชั่นที่ป้าแอนคิด กับ ที่อเมริกาเอาไปปรับใช้เป็นคนละตัวกัน แต่โลกทั้งโลกก็บูลลีป้าเอนว่า เป็นสาเหตุของการทำลายสุขภาพคนทั้งโลก ทั้งๆที่ไม่ได้เป็นนักวิทยาศาสตร์ ผมก็เป็นคนนึงที่เคยคิดแบบนั้นครับ และเคยอุทานในใจเบาๆว่า แกเป็นใครนะทำไมถึงนำเสนออะไรแบบนี้มาทำร้ายคนทั้งโลก???

นานวันเข้า ความคิดอีกฝั่งของผมก็บอกมาว่า ประโยคข้างบนเป็นคำบ่นหรือคำถาม

นั่นสิ!!!!! ถ้ามันเป็นคำถาม มันจะทำให้เราได้รู้จักตัวตนป้าแอนและเข้าใจว่าแกได้ทำอะไรลงไปนะ มันควรเป็นคำถามมากกว่าคำบ่น นั่นเลยเป็นเหตุผลที่ทำให้ผมเริ่มขุดเรื่องป้าแอน Anna Britt Agnsäter มากที่สุดเท่าที่จะทำได้ พร้อมที่จะอ่านกันแล้วใช่ไหมครับ

Anna Britt Agnsäter เกิดเมื่อปี 1915 ที่เมือง Älmhult ประเทศสวีเดน (นอกเรื่องนิดนึง เมืองนี้คือเมืองที่ให้กำเนิด IKEA ที่เรารู้จักกันดีเรื่องเฟอร์นิเจอร์ ที่นี่มีพิพิธภัณฑ์อิเกีย ซึ่งปรับปรุงมาจากโกดังแห่งแรกของเขาด้วยครับ) เรียกได้ว่า เกิดในช่วงสงครามโลกครั้งที่1 พอดีเลยครับ

ป้าแอน จบการศึกษาที่โรงเรียนสตรี ในเมือง Ystad ก่อนจะเข้ารับการฝึกสอนเพื่อเป็นครูสอนวิทยาศาสตร์ในครัวเรือน (rural domestic science teacher) ในช่วงปี 1930 ที่โรงเรียนวิทยาศาสตร์ในครัวเรือนในชนบทชื่อว่า Rimforsa ก่อนจะได้รับวุฒิการศึกษาการสอนวิทยาศาสตร์ในครัวเรือนในชนบทในปี 1939 จาก Kvinnliga medborgarskola (civic women’s school) จนกระทั่ง ปี 1943 ถึง 1945 เธอได้เดินทางไปทั่ว Norrland (พื้นที่ภาคเหนือของสวีเดน) โดยได้รับเงินสนับสนุนจาก Kooperativa Förbund (เรียกสั้นๆว่า KF หรือ สมาคมสหกรณ์ ก่อตั้งขึ้นในปี 1899 โดยสหกรณ์ผู้บริโภคในท้องถิ่น 41 แห่ง เป็นผู้นำด้านการค้าปลีกในสวีเดนโดยพัฒนารูปแบบร้านค้าใหม่และใหญ่ขึ้น และเป็นหนึ่งในกลุ่มธุรกิจหลักในสแกนดิเนเวีย ในสมัยนี้คำว่าสหกรณ์อาจจะดูเชยๆ แต่ต้องเข้าใจครับว่ายุคนั้นคือความก้าวหน้ามากๆ และต้องมีความรู้รอบด้านทั้งวิทยาศาสตร์ เศรษฐกิจ การเมือง) เพื่อบรรยายให้คนหนุ่มสาวและแม่บ้านฟังเกี่ยวกับวิธีรับมือกับเสบียงที่มีจำกัดในช่วงสงครามที่ตึงเครียด เนื่องจากอยู่ในภาวะสงครามโลกครั้งที่2

ในปี 1946 ป้าแอนได้รับการแต่งตั้งเป็นหัวหน้าของSwedish Cooperative Union หรือ Kooperativa Förbundets (KF) Provkök (experimental kitchen หรือ ภาษาสมัยนี้น่าจะใกล้เคียงกับ kitchen lab นั่นเอง) ซึ่งเป็นองค์กรที่มีอิทธิพลทางด้านอาหารเป็นอย่างมากในสวีเดน มีบทบาทสำคัญในเศรษฐกิจและสังคมสวีเดน โดยสร้างโอกาสให้แก่สมาชิกและส่งเสริมการพัฒนาที่ยั่งยืนในชุมชนต่าง ๆ ทั่วประเทศ

ป้าแอนทำงานที่นี่นานจนถึงช่วงปี 1980 ขนาดของ KF ก็ใหญ่โตขึ้นมากมาย จนขยายอำนาจและขอบเขตการทำงานไปถึงการเป็นคณะกรรมการทดสอบรสชาติซึ่งทดสอบอาหารกึ่งสำเร็จรูปและอาหารสำเร็จรูปใหม่ด้วย ในจุดนี้ ป้าแอน เล็งเห็นความสำคัญและความรับผิดชอบของผู้ผลิต/ผู้ค้าอาหาร ควรจะขยายความรับผิดชอบครอบคลุมไปจนถึงโต๊ะอาหาร (ในที่นี่น่าจะหมายถึงลูกค้า) นั่นคือเหตุผลที่การติดฉลากอาหารจึงมีความสำคัญมาก ป้าแอนได้มุ่งเน้นให้ความรู้กับผู้บริโภคว่า ‘Weigh up the price against the quality’ หรือ ให้ชั่งน้ำหนักพิจารณาให้ดี ระหว่างราคากับคุณภาพ ตลอดระยะเวลาการทำงาน Anna-Britt Agnsäter ได้รณรงค์เพื่อให้มีการแสดงข้อมูล ให้ผู้บริโภครับทราบ เพื่อคุณภาพชีวิตที่ดีขึ้นและได้ให้คำแนะนำด้านโภชนาการ เพื่อให้เข้าใจได้ง่ายขึ้น ในรูปแบบฉลากโภชนาการ

ในปี 1946 เช่นกันป้าแอนได้มีแผนในการทำ มีแผนที่จะผลิตหนังสือสอนทำอาหารสำหรับสถานการณ์ฉุกเฉิน เพราะบทเรียนในภาวะสงครามโลก ที่ป้าแอนผ่านมาตลอด แต่ไม่สามารถพิมพ์ออกมาได้เนื่องจากกระดาษขาดแคลนเนื่องจากอยู่ในภาวะหลังสงคราม

ในปี 1948-1949 ป้าแอนเดินทางไปอเมริกา เพื่อศึกษาเทคนิคการทำอาหารใหม่ๆ การผลิตภัณฑ์อาหารแช่แข็ง รวมถึงอาหารผงแห้งต่างๆ (dry powder) รวมไปถึงวิทยาศาสตร์การอาหาร (food science) ที่มหาวิทยาลัย Iowa State University การเดินทางมาอเมริกาครั้งนี้เปลี่ยนโลกของป้าแอนเป็นอย่างมาก ในตอนที่ป้าทำงานกับ KF เธอมักจะร่วมงานกับ Hemmens Forskningsinstitut (สถาบันวิจัยในประเทศ) เพื่อจัดหาเครื่องมือในครัวที่ยกระดับมาตรฐานการทำอาหารที่ดียิ่งขึ้น รวมถึงอุปกรณ์การครัว ภาชนะต่างๆที่เข้าเตาอบได้ และจากประสบการณ์ที่อเมริกานี้

ป้าแอนได้จับมือกับ โรงงานเครื่องเคลือบและพลาสติก Gustavsberg และ HFI Anna-Britt Agnsäter พัฒนาช้อนตวง ชุด4ชิ้น ที่วางซ้อนกันได้ ซึ่งเป็นการปฎิวัติวงการอาหารครั้งสำคัญของสวีเดน เรียกว่า “ชุดช้อนตวงมาตรฐาน” ซึ่งจะมีการระบุขนาดที่ชัดเจน 4 ชิ้น ประกอบไปด้วย

ซึ่งทำให้ผู้ใช้สามารถวัดปริมาณวัตถุดิบได้อย่างถูกต้องตามที่สูตรอาหารกำหนด กลายเป็นเครื่องมือที่จำเป็นในครัวเรือนและการประกอบอาหารในเชิงพาณิชย์

แม้การพัฒนา “ชุดช้อนตวงมาตรฐาน” นี้จะเริ่มต้นในสวีเดน แต่นวัตกรรมนี้มีผลกระทบที่กว้างขวางและแพร่หลายไปยังครัวเรือนและอุตสาหกรรมอาหารทั่วโลกจนถึงปัจจุบัน

ในชุดช้อนตวงมาตรฐาน original 4 คุณอาจสังเกตคำนึงที่ไม่ค่อยคุ้นสักเท่าไรคือหน่วย kryddmått

นอกจากชุดช้อนตวงมาตรฐานแล้ว ป้าแอนยังคิดค้นสิ่งต่างๆอีกมากมาย ให้กับวงการอาหารสวีเดน รวมถึงหน่วยวัดใหม่ที่เรียกว่า kryddmått นี้ด้วยครับ ซึ่งมันเป็นหน่วยวัดขนาดเล็กที่ใช้ในการตวงเครื่องเทศและวัตถุดิบปริมาณน้อย โดยหน่วยวัดนี้มีขนาด 1 มิลลิลิตร (ml)ซึ่งถูกกำหนดมาเป็นหน่วยที่เล็กที่สุดซึ่งทำให้มีการจดบันทึกสูตรได้แม่นยำยิ่งขึ้น นั่นเพราะว่า การตวงเครื่องเทศ หรือ เกลือ นั้นหากรสชาติที่เข้มข้น หรือมีการใช้มากเกินไปหรือไม่พออาจทำให้รสชาติของอาหารเปลี่ยนไป การใช้ kryddmått ช่วยให้การวัดปริมาณเครื่องเทศที่ใช้ในสูตรอาหารเป็นไปอย่างแม่นยำและสม่ำเสมอ

ถือว่าเป็นอีกผลงานคุโณปการที่ป้าแอน ฝากไว้ให้กับโลกนี้ มันมีส่วนสำคัญในการทำให้งานครัวเรือนง่ายขึ้นและมีประสิทธิภาพมากขึ้นผ่านการพัฒนาหน่วยวัดที่แม่นยำและสะดวกในการใช้งาน นวัตกรรมนี้ช่วยให้การทำอาหารเป็นไปอย่างราบรื่นและมีคุณภาพสูงยิ่งขึ้น

ในปี 1951 ป้าแอนได้บูรณะหนังสือการทำอาหารประจำสวีเดนใหม่ทั้งหมด (Vår kokbok) จุดประสงค์ของตำราอาหาร Vår คือการนำเสนอตำราอาหารราคาต้นทุนวัตถุดิบไม่แพง ที่ให้ความรู้เรื่องสารอาหารและใช้งานง่าย นอกจากนี้ยังเป็นการวางวัตถุดิบให้ได้รับสารอาหารที่เพียงพออีกด้วย เพราะในยุคนั้นสวีเดนมีข้อจำกัดในเรื่องอาหารเป็นอย่างมาก

เนื้อหาสูตรอาหารที่ใช้ในหนังสือเล่มนี้กลายเป็นบรรทัดฐานในช่วงทศวรรษ 1950 โดยมีการใช้หน่วยชั่งตวงแบบใหม่ ตามชุดช้อนตวงมาตรฐาน (ปริมาตร) จากของเดิมที่ใช้การชั่งน้ำหนัก ใช้ศัพท์ในการทำอาหารแบบเป็นสากล เช่น ขูด ปอกเปลือก ล้าง เป็นต้น (grate, peel, rinse) จัดอาร์ทเวิคให้แต่ละสูตร สามารถจบได้ในหน้าเดียวไม่ต้องพลิกอ่านหน้าต่อๆไป ทำให้สะดวกในการเปิดแล้วทำตาม การไล่ลำดับอาหาร เปลี่ยนจากการไล่ประเภทอาหาร ไปเป็นไล่ลำดับตามวัตถุดิบหลักของอาหาร ทำให้คนอ่านสามารถบริหารจัดการเมนูได้ง่าย เช่น ไก่ ก็สามารถไล่เรียงได้เลยว่า วันนี้มีไก่ จะทำอะไรกินดี

นอกจากนี้ยังรับประกันว่าทุกสูตรสามารถทำได้จริง เพราะป้าแอนลงมือทดสอบสูตรด้วยตัวเองทุกสูตร นอกจากนี้ยังคงมีการแนะนำให้ใช้การวัดอุณหภูมิในการทำอาหารด้วยเพื่อความเป๊ะในรสชาติ เนื่องจากป้าแอนเห็นตอนไปดูงานที่อเมริกา จนถึงทุกวันนี้ Vår kokbok เป็นหนึ่งในตำราอาหารที่ขายมากที่สุดในโลกด้วยยอดขายมากกว่า 2.3 ล้านเล่มนับตั้งแต่เริ่มต้น โดยเฉลี่ยมากกว่า 40,000 เล่มต่อปี

ด้วยความที่ Kooperativa Förbundets เป็นองค์กรที่มีอิทธิพลสูงมากในวงการอาหารสวีเดน และคุณป้าแอน ก็มีตำแหน่งที่สูงมาก จึงสามารถเป็นผู้มีส่วนสนับสนุนรูปแบบซูเปอร์มาร์เก็ตสมัยใหม่ ในการใส่รายการส่วนผสมและคำแนะนำในการปรุงอาหารในรูปแบบฉลากของผลิตภัณฑ์อาหารสมัยใหม่

จนกระทั่งในช่วงปี 1970 ประเทศสวีเดนต้องเผชิญกับปัญหาราคาอาหารที่สูงเนื่องจากเงินเฟ้อ รวมถึงสภาพอากาศของสวีเดนนั้น ไม่เอื้อต่อการได้รับสารอาหารที่หลากหลายได้ ครอบครัวที่มีเด็ก ไม่สามารถปรุงอาหารและรับประทานอาหารที่มีคุณค่าทางโภชนาการในราคาที่เหมาะสมได้ รัฐบาลจึงมอบหมายให้ Sweden’s National Board of Health and Welfare (คณะกรรมการสุขภาพและสวัสดิการแห่งชาติของสวีเดน) หาวิธีแก้ไขสถานการณ์ดังกล่าว และคัดกรองแบ่งประเภทอาหารออกเป็น “basic food” และ “supplement” มาเป็นรูปแบบของ กราฟวงกลม (diet circle) แต่ป้าแอนพบปัญหาบางอย่าง ที่ทำให้กราฟวงกลมนี้ใช้งานยาก เพราะการแบ่งปริมาณของอาหารแต่ละประเภทไม่ชัดเจน

ในระหว่างบรรยายเรื่องการกำหนดอาหารพื้นฐาน คุณ Fjalar Clemes หนึ่งในผู้เข้าร่วมการบรรยาย ได้ให้ไอเดียด้วยการสร้างแบบจำลองที่เรียกว่า ปิรามิดอาหาร (Food Pyramid) ขึ้นมา เพื่อให้เห็นภาพสัดส่วนอาหารที่ชัดเจนขึ้น ป้าแอนเลยนำข้อมูลจากกราฟวงกลมนั้น มาสร้างโมเดลจำลองให้อยู่ในรูปแบบปิรามิด โดยให้ “basic food” เช่น ขนมปัง มันฝรั่ง พาสต้า และนม และ “supplements” เช่น ผลไม้ ผัก เนื้อสัตว์ และปลา อยู่ในรูปแบบที่เข้าใจได้ง่ายขึ้น แม้แต่คนที่อ่านหนังสือไม่ออก

แต่นี่แหละที่เป็นจุดเริ่มต้นของปัญหา ด้วยความที่มันใช้งานง่ายสะดวก อเมริกาจึงนำไปปรับปรุงเป็นเวอร์ชั่นตัวเอง แต่ก็มีการเปลี่ยนแปลงไปอย่างมาก ตามที่ได้มีการทำบทความไปแล้ว (อ่านที่นี่)

ทั้งๆที่ปิรามิดต้นแบบของป้าแอนนั้น สร้างขึ้นมาเพื่อชาวสวีเดนเนื่องจากนำข้อมูลพื้นฐานจากข้อจำกัดในประเทศในขณะนั้น ไม่ว่าจะเรื่องของวัตถุดิบที่หาได้ในภาวะยากแค้นแบบนั้น อุณหภูมิอันปรวนแปร รวมถึงสภาพเศรษฐกิจที่ย่ำแย่มาก การจัดแจงข้อจำกัดที่มีเพื่อให้ได้สารอาหารที่เพียงพอที่สุดเท่าที่จะทำได้ต่างหาก (eat healthier, more affordable and save on fat) ที่เป็นที่มาของ “ปิรามิดอาหารของสวีเดน” (คือ จะให้เอาอุดมคติมาสร้างปิรามิดอาหาร คงไม่มีประโยชน์ เพราะยังไงก็ไม่มีเงินซื้อและหาวัตถุดิบไมไ่ด้ตามอุดมคติ วัตถุประสงค์ในการสร้างและเผยแพร่ครั้งนี้มันเพื่อให้ประชาชนทั้งประเทศที่มีความรู้ด้านอาหารน้อย รู้และทำตามได้จริง สมกับพื้นที่และกำลังทรัพย์ // ความเห็นส่วนตัวผมครับ)

ปิรามิดอาหารที่แท้จริงแล้ว จะมีการปรับปรุงตลอดเวลา ตามปัจจัยที่เปลี่ยนไป ไม่ใช่ปิรามิดที่เอาไว้ยึดถือตลอดไป แต่การที่อเมริกานำไปยึดถือว่าเป็น all time information เป็นค่าคงที่ให้ทั้งโลกยึดตาม รวมถึงสร้างด้วยเบื้องหลังด้านธุรกิจ จึงต่างกับที่ป้าแอนทำในทุกมิติ แต่ไฉน เป้าการบูลลี จึงต้องไปตกที่ป้าแอน ว่าเป็นต้นตอความพังของสุขภาพ มันแฟร์แล้วหรือ

เรื่องนี้มีข้อพิสูจน์ได้จนถึงปัจจุบันเช่น ในปี 2022 ก็มีการนำเสนอ ปิรามิดอาหารสำหรับ Mixed diet, flexitarian, vegetarian และ vegan ออกมาสืบทอดเจตนารมณ์ป้าแอน นอกจากนี้ในช่วงที่ป้าแอนมีชีวิต ก็ยังคงมีการช่วยเหลือแนะนำให้ประเทศต่างๆ “มีปิรามิดอาหารของตัวเอง” นั่นคือ วิชั่นที่กว้างไกลของป้าแอน ที่เห็นได้ชัดเจนว่า อาหารพื้นถิ่นกับสารอาหารที่สมดุล ของแต่ละประเทศมีความไม่เหมือนกัน และแนวคิดนี้ได้มีทั้ง เดนมาร์ก, นอร์เวย์, ฟินแลนด์, ญี่ปุ่น, ศรีลังกา ได้นำไปพัฒนาใช้เช่นกัน

นอกจากนี้ ป้าแอนและองค์กร Kooperativa Förbundets ยังให้ข้อมูลการศึกษาที่สำคัญสำหรับประชาชนผ่านบทความเกี่ยวกับอาหารที่ตีพิมพ์ใน นิตยสาร Vi รวมถึงการจัดตั้งกลุ่มการศึกษาร่วมกับทาง สมาคมการศึกษาของชนชั้นแรงงาน หรือ Arbetarnas bildningsförbund (ABF) มีส่วนสนับสนุนในการอภิปรายแบบเปิดทางสังคมเกี่ยวกับปัญหาโรคอ้วนอีกด้วย รวมถึงยังออกหนังสือเกี่ยวกับการทำอาหารอีกร่วมๆ 30เล่ม ซึ่งรวมถึงบทเกี่ยวกับมื้ออาหารที่มีคุณค่าทางโภชนาการที่สมดุล ด้วยเช่นกัน

ในปี 1983 ป้าแอนได้ตีพิมพ์หนังสือ Matboken ซึ่งได้รับการพิสูจน์แล้วว่าเป็นประโยชน์อย่างมาก โดยเฉพาะกับคนหนุ่มสาวเกี่ยวกับวิธีการกินอาหารที่มีคุณค่าทางโภชนาการและมีวิธีทำที่เรียบง่ายที่สุด

ในช่วงทศวรรษ 1990 เมื่อป้าแอนเป็นม่าย จึงได้ย้ายเข้าไปอยู่ในบ้านพักคนชรา Färdknäppen ใน Södermalm ในสตอกโฮล์ม และ ได้แก้ไขสูตรอาหาร 250 สูตรจาก Vår kokbok เพื่อให้เหมาะสมกับสภาพแวดล้อมการปรุงอาหารส่วนกลางของบ้านพักคนชรา เพื่อให้ได้อาหารที่มีสารอาหารครบถ้วนตามที่ควรเป็น

เกียรติประวัติป้าแอนได้รับการตอบแทนดังนี้ ในปี 1979 ได้รับรางวัลเหรียญ St Erik เพื่อเป็นการยกย่องสิ่งที่เธอทุ่มเทแรงกายแรงใจทำมาตลอดชีวิต ในปี 1993 ได้รับเหรียญ HM Konungens ลำดับที่ 8 (HM The King’s Medal หรือ H.M. Konungens medalj ในภาษาสวีเดน) เป็นหนึ่งในรางวัลเกียรติยศที่สำคัญที่สุดที่มอบโดยพระมหากษัตริย์สวีเดนเพื่อยกย่องบุคคลที่มีผลงานดีเด่นหรือมีความโดดเด่นในด้านต่าง ๆ เช่น วิทยาศาสตร์ ศิลปะ วัฒนธรรม และการบริการสาธารณะ ในปี 1995 ได้รับเหรียญทอง Albin Johansson สำหรับผลงานอันทรงคุณค่าของเธอต่อสหกรณ์สวีเดน ในปี 1998 ได้รับรางวัล Gastronomiska Akademiens Guldpenna (ปากกาทองของสถาบันอาหาร) สำหรับบทความเกี่ยวกับส่วนผสมและการทำอาหารของเธอ

Anna-Britt Agnsäter เสียชีวิตในปี 2006 (อายุ 90ปี) ป้าแอนทำงานทั้งชีวิตเพื่อสอนชาวสวีเดนในการจัดการอาหารให้ดีขึ้น ทุกการทดลอง ทดสอบ ได้มีการบันทึกไว้อย่างชัดเจนสามารถพัฒนาต่อไปได้ การริเริ่มให้ข้อมูลที่ซื่อสัตย์ต่อผู้บริโภค ทั้งการติดฉลากอุปกรณ์ คำแนะนำในการทำอาหาร สูตรอาหาร บทความ และตำราอาหาร สิ่งเหล่านี้กลายเป็นพื้นฐานสำคัญในอุตสาหกรรมอาหารจนปัจจุบัน

แต่ทุกวันนี้วงการสุขภาพส่วนมากยังคงล้อเลียนเธอว่าเป็นครูธรรมดา ที่มีหน้ามาสร้างปิรามิดอาหาร จึงทำให้คนทั่งโลกป่วย ทั้งที่ความจริงทั้งหมดนั้น ความรู้ของป้าแอนไม่ได้น้อยไปกว่า ผู้เชี่ยวชาญทางวิทยาศาสตร์การอาหาร ซึ่งในสมัยนั้นนับว่าเป็นอีกแขนงที่อยู่ในระดับบนของการศึกษา ไม่ต่างกับวิทยาศาสตร์อื่นๆ ปิรามิดควรเป็นไปตามถิ่นที่อยู่ สภาพเวลาและสภาพเศรษฐกิจขณะนั้น ไม่ใช่การสร้างมาตรฐานให้ต้องทำเหมือนกันทั่วโลก โดยมาจากอิทธิพลของกลุ่มธุรกิจดังที่ usda ได้ทำการแก้ไขก่อนจะประกาศให้คนทั่วไปยึดถือ รายละเอียดเป็นไปตามที่สืบค้นข้อมูลประวัติของป้าแอน มาเล่าสู่กันฟัง ณ วันนี้ครับ

ผมก็เป็นหนึ่งในนั้น สิ่งที่ผมสามารถทำได้เพื่อเป็นการขอโทษคุณ Anna-Britt Agnsäter ที่ดีที่สุดที่ทำได้ตอนนี้คือ เผยแพร่ประวัติอันทรงคุณค่าของเธอ ให้คนอื่นๆได้รับทราบมากที่สุด เท่าที่จะทำได้

โปรดแชร์ เพื่อคืนความเป็นธรรมให้ Anna-Britt Agnsäter ให้โลกได้เข้าใจและรับรู้ถึงการอุทิศชีวิตให้วงการอาหารของคุณป้าครับ

At-Risk Groups Are Facing A Battle For Their Rights

Privacy. It’s a word we often take for granted, scrolling through our phones and sharing photos without a second thought. But for certain groups—those at risk due to their identities, beliefs, or circumstances—privacy isn’t just a luxury; it’s a lifeline. In today’s world, where governments, corporations, and even our own social media accounts seem to have a vested interest in collecting and selling our data, the fight for privacy has never been more crucial.

Privacy is not a buzzword but a fundamental human right. We can do more to protect those who need it most.

Privacy As A Human Right

The concept of privacy is deeply rooted in our basic human rights. It’s not just about keeping your medical records confidential or hiding your bank statements; it’s about the right to control what others can know about you. For individuals who identify as LGBTQ+, immigrants, journalists, or political dissidents, this right is even more fragile.

Recently, we’ve seen a rise in policies that seem designed to strip away these protections. From the Trump administration’s transgender ban on military service and passport changes to the targeting of journalists and activists, the message is clear: certain groups are considered fair game for scrutiny and control.

These actions are about erasing the autonomy of individuals to live their lives without fear of retribution or discrimination. Privacy isn’t just a feel-good concept; it’s the cornerstone of a individuals liberty. We must ensure that no one’s rights can be arbitrarily taken away, especially the right to privacy.

The Attack On Vulnerable Groups

The targeting of at-risk groups has reached a fever pitch in recent months:
1. Transgender Rights Under Fire
  The Trump administration has issued a sweeping executive order that effectively erased recognition of transgender individuals’ rights. This included changes to passport policies that required individuals to declare their gender at birth, making it nearly impossible for trans individuals to update their documents without facing extreme scrutiny or even denial.
These actions don’t just impact transgender people; they send a chilling message to the entire LGBTQ+ community.
1. Free Speech And Political Dissent
  Trump’s Free Speech Executive Order, aimed to protect citizens’ right to express their beliefs. However, critics argue it was more about silencing dissenters. Journalists, activists, and even private citizens have faced increasing pressure from government officials to either comply with certain views or face professional consequences.
“Free speech is a double-edged sword,” noted one legal expert. “When the government uses it as a tool to marginalize certain groups, it becomes a weapon rather than a shield.”
1. Media And Press Freedom
  Trump’s ongoing battles with major media outlets are well-documented. From labeling reporters as “fake news” to pushing for laws that would limit press freedom, the administration has made it clear that journalists and news organizations are not above scrutiny. For independent journalists and investigative reporters, this poses a significant threat to their work and safety.
2. Immigrant Rights And Discrimination
  The Trump administration’s harsh immigration policies have had a devastating impact on vulnerable communities. From family separations to the expansion of surveillance in immigrant-heavy areas, these actions have left many feeling exposed and unsafe. Immigrants, particularly those from Latin America and the Middle East, are increasingly targeted for their perceived alignments with political rhetoric.
The Consequences Of Losing Privacy

When privacy is stripped away, it doesn’t just affect individuals—it affects entire communities. For transgender individuals, the fear of being “outted” online or facing discrimination at work is a daily reality. For journalists, the threat of government retribution can lead to self-censorship and an inability to hold power accountable. For immigrants, the risk of deportation or surveillance means constant vigilance—and often, no recourse.

These consequences are not just personal; they’re systemic. When certain groups are deemed unworthy of protection, it sets a dangerous precedent for what’s allowed in society. It sends the message that some lives matter less than others, and that the government can act with impunity. If you are not in one of these currently impacted groups just give it time and eventually they will come for you too.

The Fight For Privacy: What We Can Do

The good news is that we don’t have to sit idly by while this happens. There are steps we can take to fight for privacy as a fundamental right. Here’s how:
1. Advocate For Stronger Protections
  Governments at all levels need to pass and enforce laws that protect privacy, especially for vulnerable groups. This includes everything from data protection legislation to anti-discrimination policies.
2. Support Independent Journalism
  Journalists are on the front lines of this fight, uncovering corruption and holding power accountable. Support independent media outlets and platforms that prioritize transparency and press freedom.
3. Educate And Empower
  Communities under threat need resources to protect themselves. This includes education on their rights, know how and tools to secure their data, and access to legal support when needed.
4. Use Your Voice
  Speak out against policies that erode privacy and target vulnerable groups. Use your actions to protect yourself and others.
5. Demand Accountability
  When governments overreach, they need to be held accountable. Fight for yours and others rights.
Privacy Is A Fight Worth Winning

Privacy isn’t just about convenience or comfort—it’s about freedom, autonomy, and the right to live without fear of arbitrary control. For at-risk groups, this is not just a luxury; it’s a lifeline. As we move forward in this uncertain era, let’s remember that the fight for privacy is not over— it’s just beginning.

We all have a role to play in protecting those who need it most. So let’s get to work.

Konsum ist Therapie.
Wolfgang Joop

Umweltbewusstes Verhalten und verantwortungsvoller Konsum zeugen durchaus von einer wünschenswerten Einstellung. Ob man deswegen allerdings einen grünen statt eines schwarzen Freitags braucht, darf getrost bezweifelt werden – zumal es sich um manipulatorische Konzepte handelt. Wie in der politischen Landschaft sind auch hier die Etiketten irgendwas zwischen nichtssagend und trügerisch.

Heute ist also wieder mal «Black Friday», falls Sie es noch nicht mitbekommen haben sollten. Eigentlich haben wir ja eher schon eine ganze «Black Week», der dann oft auch noch ein «Cyber Monday» folgt. Die Werbebranche wird nicht müde, immer neue Anlässe zu erfinden oder zu importieren, um uns zum Konsumieren zu bewegen. Und sie ist damit sehr erfolgreich.

Warum fallen wir auf derartige Werbetricks herein und kaufen im Zweifelsfall Dinge oder Mengen, die wir sicher nicht brauchen? Pure Psychologie, würde ich sagen. Rabattschilder triggern etwas in uns, was den Verstand in Stand-by versetzt. Zusätzlich beeinflussen uns alle möglichen emotionalen Reize und animieren uns zum Schnäppchenkauf.

Gedankenlosigkeit und Maßlosigkeit können besonders bei der Ernährung zu ernsten Problemen führen. Erst kürzlich hat mir ein Bekannter nach einer USA-Reise erzählt, dass es dort offenbar nicht unüblich ist, schon zum ausgiebigen Frühstück in einem Restaurant wenigstens einen Liter Cola zu trinken. Gerne auch mehr, um das Gratis-Nachfüllen des Bechers auszunutzen.

Kritik am schwarzen Freitag und dem unnötigen Konsum kommt oft von Umweltschützern. Neben Ressourcenverschwendung, hohem Energieverbrauch und wachsenden Müllbergen durch eine zunehmende Wegwerfmentalität kommt dabei in der Regel auch die «Klimakrise» auf den Tisch.

Die EU-Kommission lancierte 2015 den Begriff «Green Friday» im Kontext der überarbeiteten Rechtsvorschriften zur Kennzeichnung der Energieeffizienz von Elektrogeräten. Sie nutzte die Gelegenheit kurz vor dem damaligen schwarzen Freitag und vor der UN-Klimakonferenz COP21, bei der das Pariser Abkommen unterzeichnet werden sollte.

Heute wird ein grüner Freitag oft im Zusammenhang mit der Forderung nach «nachhaltigem Konsum» benutzt. Derweil ist die Europäische Union schon weit in ihr Geschäftsmodell des «Green New Deal» verstrickt. In ihrer Propaganda zum Klimawandel verspricht sie tatsächlich «Unterstützung der Menschen und Regionen, die von immer häufigeren Extremwetter-Ereignissen betroffen sind». Was wohl die Menschen in der Region um Valencia dazu sagen?

Ganz im Sinne des Great Reset propagierten die Vereinten Nationen seit Ende 2020 eine «grüne Erholung von Covid-19, um den Klimawandel zu verlangsamen». Der UN-Umweltbericht sah in dem Jahr einen Schwerpunkt auf dem Verbraucherverhalten. Änderungen des Konsumverhaltens des Einzelnen könnten dazu beitragen, den Klimaschutz zu stärken, hieß es dort.

Der Begriff «Schwarzer Freitag» wurde in den USA nicht erstmals für Einkäufe nach Thanksgiving verwendet – wie oft angenommen –, sondern für eine Finanzkrise. Jedoch nicht für den Börsencrash von 1929, sondern bereits für den Zusammenbruch des US-Goldmarktes im September 1869. Seitdem mussten die Menschen weltweit so einige schwarze Tage erleben.

Kürzlich sind die britischen Aufsichtsbehörden weiter von ihrer Zurückhaltung nach dem letzten großen Finanzcrash von 2008 abgerückt. Sie haben Regeln für den Bankensektor gelockert, womit sie «verantwortungsvolle Risikobereitschaft» unterstützen wollen. Man würde sicher zu schwarz sehen, wenn man hier ein grünes Wunder befürchten würde.

Imagine sending a private message to a friend, only to learn that authorities could be scanning its contents without your knowledge. This isn't a scene from a dystopian novel but a potential reality under the European Union's proposed "Chat Control" measures. Aimed at combating serious crimes like child exploitation and terrorism, these proposals could significantly impact the privacy of everyday internet users. As encrypted messaging services become the norm for personal and professional communication, understanding Chat Control is essential. This article delves into what Chat Control entails, why it's being considered, and how it could affect your right to private communication.

What Is Chat Control?

"Chat Control" refers to a set of proposed measures by the European Union aimed at monitoring and scanning private communications on messaging platforms. The primary goal is to detect and prevent the spread of illegal content, such as child sexual abuse material (CSAM) and to combat terrorism. While the intention is to enhance security and protect vulnerable populations, these proposals have raised significant privacy concerns.

At its core, Chat Control would require messaging services to implement automated scanning technologies that can analyze the content of messages—even those that are end-to-end encrypted. This means that the private messages you send to friends, family, or colleagues could be subject to inspection by algorithms designed to detect prohibited content.

Origins of the Proposal

The initiative for Chat Control emerged from the EU's desire to strengthen its digital security infrastructure. High-profile cases of online abuse and the use of encrypted platforms by criminal organizations have prompted lawmakers to consider more invasive surveillance tactics. The European Commission has been exploring legislation that would make it mandatory for service providers to monitor communications on their platforms.

How Messaging Services Work

Most modern messaging apps, like Signal, Session, SimpleX, Veilid, Protonmail and Tutanota (among others), use end-to-end encryption (E2EE). This encryption ensures that only the sender and the recipient can read the messages being exchanged. Not even the service providers can access the content. This level of security is crucial for maintaining privacy in digital communications, protecting users from hackers, identity thieves, and other malicious actors.

Key Elements of Chat Control
- Automated Content Scanning: Service providers would use algorithms to scan messages for illegal content.
- Circumvention of Encryption: To scan encrypted messages, providers might need to alter their encryption methods, potentially weakening security.
- Mandatory Reporting: If illegal content is detected, providers would be required to report it to authorities.
- Broad Applicability: The measures could apply to all messaging services operating within the EU, affecting both European companies and international platforms.
Why It Matters

Understanding Chat Control is essential because it represents a significant shift in how digital privacy is handled. While combating illegal activities online is crucial, the methods proposed could set a precedent for mass surveillance and the erosion of privacy rights. Everyday users who rely on encrypted messaging for personal and professional communication might find their conversations are no longer as private as they once thought.

Why Is the EU Pushing for Chat Control?

The European Union's push for Chat Control stems from a pressing concern to protect its citizens, particularly children, from online exploitation and criminal activities. With the digital landscape becoming increasingly integral to daily life, the EU aims to strengthen its ability to combat serious crimes facilitated through online platforms.

Protecting Children and Preventing Crime

One of the primary motivations behind Chat Control is the prevention of child sexual abuse material (CSAM) circulating on the internet. Law enforcement agencies have reported a significant increase in the sharing of illegal content through private messaging services. By implementing Chat Control, the EU believes it can more effectively identify and stop perpetrators, rescue victims, and deter future crimes.

Terrorism is another critical concern. Encrypted messaging apps can be used by terrorist groups to plan and coordinate attacks without detection. The EU argues that accessing these communications could be vital in preventing such threats and ensuring public safety.

Legal Context and Legislative Drivers

The push for Chat Control is rooted in several legislative initiatives:
- ePrivacy Directive: This directive regulates the processing of personal data and the protection of privacy in electronic communications. The EU is considering amendments that would allow for the scanning of private messages under specific circumstances.
- Temporary Derogation: In 2021, the EU adopted a temporary regulation permitting voluntary detection of CSAM by communication services. The current proposals aim to make such measures mandatory and more comprehensive.
- Regulation Proposals: The European Commission has proposed regulations that would require service providers to detect, report, and remove illegal content proactively. This would include the use of technologies to scan private communications.
Balancing Security and Privacy

EU officials argue that the proposed measures are a necessary response to evolving digital threats. They emphasize the importance of staying ahead of criminals who exploit technology to harm others. By implementing Chat Control, they believe law enforcement can be more effective without entirely dismantling privacy protections.

However, the EU also acknowledges the need to balance security with fundamental rights. The proposals include provisions intended to limit the scope of surveillance, such as:
- Targeted Scanning: Focusing on specific threats rather than broad, indiscriminate monitoring.
- Judicial Oversight: Requiring court orders or oversight for accessing private communications.
- Data Protection Safeguards: Implementing measures to ensure that data collected is handled securely and deleted when no longer needed.
The Urgency Behind the Push

High-profile cases of online abuse and terrorism have heightened the sense of urgency among EU policymakers. Reports of increasing online grooming and the widespread distribution of illegal content have prompted calls for immediate action. The EU posits that without measures like Chat Control, these problems will continue to escalate unchecked.

Criticism and Controversy

Despite the stated intentions, the push for Chat Control has been met with significant criticism. Opponents argue that the measures could be ineffective against savvy criminals who can find alternative ways to communicate. There is also concern that such surveillance could be misused or extended beyond its original purpose.

The Privacy Concerns and Risks

While the intentions behind Chat Control focus on enhancing security and protecting vulnerable groups, the proposed measures raise significant privacy concerns. Critics argue that implementing such surveillance could infringe on fundamental rights and set a dangerous precedent for mass monitoring of private communications.

Infringement on Privacy Rights

At the heart of the debate is the right to privacy. By scanning private messages, even with automated tools, the confidentiality of personal communications is compromised. Users may no longer feel secure sharing sensitive information, fearing that their messages could be intercepted or misinterpreted by algorithms.

Erosion of End-to-End Encryption

End-to-end encryption (E2EE) is a cornerstone of digital security, ensuring that only the sender and recipient can read the messages exchanged. Chat Control could necessitate the introduction of "backdoors" or weaken encryption protocols, making it easier for unauthorized parties to access private data. This not only affects individual privacy but also exposes communications to potential cyber threats.

Concerns from Privacy Advocates

Organizations like Signal and Tutanota, which offer encrypted messaging services, have voiced strong opposition to Chat Control. They warn that undermining encryption could have far-reaching consequences:
- Security Risks: Weakening encryption makes systems more vulnerable to hacking, espionage, and cybercrime.
- Global Implications: Changes in EU regulations could influence policies worldwide, leading to a broader erosion of digital privacy.
- Ineffectiveness Against Crime: Determined criminals might resort to other, less detectable means of communication, rendering the measures ineffective while still compromising the privacy of law-abiding citizens.
Potential for Government Overreach

There is a fear that Chat Control could lead to increased surveillance beyond its original scope. Once the infrastructure for scanning private messages is in place, it could be repurposed or expanded to monitor other types of content, stifling free expression and dissent.

Real-World Implications for Users
- False Positives: Automated scanning technologies are not infallible and could mistakenly flag innocent content, leading to unwarranted scrutiny or legal consequences for users.
- Chilling Effect: Knowing that messages could be monitored might discourage people from expressing themselves freely, impacting personal relationships and societal discourse.
- Data Misuse: Collected data could be vulnerable to leaks or misuse, compromising personal and sensitive information.
Legal and Ethical Concerns

Privacy advocates also highlight potential conflicts with existing laws and ethical standards:
- Violation of Fundamental Rights: The European Convention on Human Rights and other international agreements protect the right to privacy and freedom of expression.
- Questionable Effectiveness: The ethical justification for such invasive measures is challenged if they do not significantly improve safety or if they disproportionately impact innocent users.
Opposition from Member States and Organizations

Countries like Germany and organizations such as the European Digital Rights (EDRi) have expressed opposition to Chat Control. They emphasize the need to protect digital privacy and caution against hasty legislation that could have unintended consequences.

The Technical Debate: Encryption and Backdoors

The discussion around Chat Control inevitably leads to a complex technical debate centered on encryption and the potential introduction of backdoors into secure communication systems. Understanding these concepts is crucial to grasping the full implications of the proposed measures.

What Is End-to-End Encryption (E2EE)?

End-to-end encryption is a method of secure communication that prevents third parties from accessing data while it's transferred from one end system to another. In simpler terms, only the sender and the recipient can read the messages. Even the service providers operating the messaging platforms cannot decrypt the content.
- Security Assurance: E2EE ensures that sensitive information—be it personal messages, financial details, or confidential business communications—remains private.
- Widespread Use: Popular messaging apps like Signal, Session, SimpleX, Veilid, Protonmail and Tutanota (among others) rely on E2EE to protect user data.
How Chat Control Affects Encryption

Implementing Chat Control as proposed would require messaging services to scan the content of messages for illegal material. To do this on encrypted platforms, providers might have to:
- Introduce Backdoors: Create a means for third parties (including the service provider or authorities) to access encrypted messages.
- Client-Side Scanning: Install software on users' devices that scans messages before they are encrypted and sent, effectively bypassing E2EE.
The Risks of Weakening Encryption

1. Compromised Security for All Users

Introducing backdoors or client-side scanning tools can create vulnerabilities:
- Exploitable Gaps: If a backdoor exists, malicious actors might find and exploit it, leading to data breaches.
- Universal Impact: Weakening encryption doesn't just affect targeted individuals; it potentially exposes all users to increased risk.
2. Undermining Trust in Digital Services
- User Confidence: Knowing that private communications could be accessed might deter people from using digital services or push them toward unregulated platforms.
- Business Implications: Companies relying on secure communications might face increased risks, affecting economic activities.
3. Ineffectiveness Against Skilled Adversaries
- Alternative Methods: Criminals might shift to other encrypted channels or develop new ways to avoid detection.
- False Sense of Security: Weakening encryption could give the impression of increased safety while adversaries adapt and continue their activities undetected.
Signal’s Response and Stance

Signal, a leading encrypted messaging service, has been vocal in its opposition to the EU's proposals:
- Refusal to Weaken Encryption: Signal's CEO Meredith Whittaker has stated that the company would rather cease operations in the EU than compromise its encryption standards.
- Advocacy for Privacy: Signal emphasizes that strong encryption is essential for protecting human rights and freedoms in the digital age.
Understanding Backdoors

A "backdoor" in encryption is an intentional weakness inserted into a system to allow authorized access to encrypted data. While intended for legitimate use by authorities, backdoors pose several problems:
- Security Vulnerabilities: They can be discovered and exploited by unauthorized parties, including hackers and foreign governments.
- Ethical Concerns: The existence of backdoors raises questions about consent and the extent to which governments should be able to access private communications.
The Slippery Slope Argument

Privacy advocates warn that introducing backdoors or mandatory scanning sets a precedent:
- Expanded Surveillance: Once in place, these measures could be extended to monitor other types of content beyond the original scope.
- Erosion of Rights: Gradual acceptance of surveillance can lead to a significant reduction in personal freedoms over time.
Potential Technological Alternatives

Some suggest that it's possible to fight illegal content without undermining encryption:
- Metadata Analysis: Focusing on patterns of communication rather than content.
- Enhanced Reporting Mechanisms: Encouraging users to report illegal content voluntarily.
- Investing in Law Enforcement Capabilities: Strengthening traditional investigative methods without compromising digital security.
The technical community largely agrees that weakening encryption is not the solution:
- Consensus on Security: Strong encryption is essential for the safety and privacy of all internet users.
- Call for Dialogue: Technologists and privacy experts advocate for collaborative approaches that address security concerns without sacrificing fundamental rights.

The probability of AGI ending us is negative.

A common tactic among doomers is to state something along the lines of the following:

"If we create AGI, there is some non-zero chance every year, that the AGI will end humanity. Whatever that chance is compounds every year, and is thus unacceptable."

The question I would ask the doomer is "How do you know that the chance of AGI ending humanity isn't negative?"

What does it mean for AGI to have a negative chance of ending humanity?

Setting aside AGI for a moment, what is the chance every year that humanity ends from other events, such as nuclear war, solar flares, super-volcanoes, asteroid hits, societal collapse, etc?

How do you even answer this question in a reasonable manner? Well lets look at past data.

Of all species that have existed 99% have gone extinct.

Of our closest 7 relatives from the genus Homo, 100% have gone extinct.

On a higher level looking at civilizational collapse. According to Wikipedia, virtually all historical societies have collapsed.

Looking out into the universe, we see no signs of life elsewhere, so if there was life in the past we can assume that they have gone extinct.

It would therefore be reasonable to say that the chance of our extinction is very high even without AGI, well above 90%. Maybe 99%.

You could argue the numbers but at least with these numbers we are using some past data to extrapolate the future, where the doomers are using no data whatsoever to support their numbers.

We can also state, that of all the species and societies that have collapsed in the past, they have done so because they did not yet have the knowledge on how to survive. They didn't know how to create antibiotics, or generate enough energy, or defend themselves from the environment.

What is AGI? AGI is a way to create knowledge. Most all societies in the past have collapsed because they didn't have the knowledge on how to survive, and the doomer argument is that we should slow down our ability to create knowledge, when we know that this has been precisely the problem in the past.

It is a certainty we will all die without more knowledge then we have now. The future death of our sun ensures that.

We have to create the knowledge on how to survive, and that is what AGI does - it creates knowledge.

AGI most certainly has a negative probability of ending humanity.

Und plötzlich weißt du:
Es ist Zeit, etwas Neues zu beginnen
und dem Zauber des Anfangs zu vertrauen.
Meister Eckhart

Schwarz, rot, gold leuchtet es im Kopf des Newsletters der deutschen Bundesregierung, der mir freitags ins Postfach flattert. Rot, gelb und grün werden daneben sicher noch lange vielzitierte Farben sein, auch wenn diese nie geleuchtet haben. Die Ampel hat sich gerade selber den Stecker gezogen – und hinterlässt einen wirtschaftlichen und gesellschaftlichen Trümmerhaufen.

Mit einem bemerkenswerten Timing hat die deutsche Regierungskoalition am Tag des «Comebacks» von Donald Trump in den USA endlich ihr Scheitern besiegelt. Während der eine seinen Sieg bei den Präsidentschaftswahlen feierte, erwachten die anderen jäh aus ihrer Selbsthypnose rund um Harris-Hype und Trump-Panik – mit teils erschreckenden Auswüchsen. Seit Mittwoch werden die Geschicke Deutschlands nun von einer rot-grünen Minderheitsregierung «geleitet» und man steuert auf Neuwahlen zu.

Das Kindergarten-Gehabe um zwei konkurrierende Wirtschaftsgipfel letzte Woche war bereits bezeichnend. In einem Strategiepapier gestand Finanzminister Lindner außerdem den «Absturz Deutschlands» ein und offenbarte, dass die wirtschaftlichen Probleme teilweise von der Ampel-Politik «vorsätzlich herbeigeführt» worden seien.

Lindner und weitere FDP-Minister wurden also vom Bundeskanzler entlassen. Verkehrs- und Digitalminister Wissing trat flugs aus der FDP aus; deshalb darf er nicht nur im Amt bleiben, sondern hat zusätzlich noch das Justizministerium übernommen. Und mit Jörg Kukies habe Scholz «seinen Lieblingsbock zum Obergärtner», sprich: Finanzminister befördert, meint Norbert Häring.

Es gebe keine Vertrauensbasis für die weitere Zusammenarbeit mit der FDP, hatte der Kanzler erklärt, Lindner habe zu oft sein Vertrauen gebrochen. Am 15. Januar 2025 werde er daher im Bundestag die Vertrauensfrage stellen, was ggf. den Weg für vorgezogene Neuwahlen freimachen würde.

Apropos Vertrauen: Über die Hälfte der Bundesbürger glauben, dass sie ihre Meinung nicht frei sagen können. Das ging erst kürzlich aus dem diesjährigen «Freiheitsindex» hervor, einer Studie, die die Wechselwirkung zwischen Berichterstattung der Medien und subjektivem Freiheitsempfinden der Bürger misst. «Beim Vertrauen in Staat und Medien zerreißt es uns gerade», kommentierte dies der Leiter des Schweizer Unternehmens Media Tenor, das die Untersuchung zusammen mit dem Institut für Demoskopie Allensbach durchführt.

«Die absolute Mehrheit hat absolut die Nase voll», titelte die Bild angesichts des «Ampel-Showdowns». Die Mehrheit wolle Neuwahlen und die Grünen sollten zuerst gehen, lasen wir dort.

Dass «Insolvenzminister» Robert Habeck heute seine Kandidatur für das Kanzleramt verkündet hat, kann nur als Teil der politmedialen Realitätsverweigerung verstanden werden. Wer allerdings denke, schlimmer als in Zeiten der Ampel könne es nicht mehr werden, sei reichlich optimistisch, schrieb Uwe Froschauer bei Manova. Und er kenne Friedrich Merz schlecht, der sich schon jetzt rhetorisch auf seine Rolle als oberster Feldherr Deutschlands vorbereite.

Was also tun? Der Schweizer Verein «Losdemokratie» will eine Volksinitiative lancieren, um die Bestimmung von Parlamentsmitgliedern per Los einzuführen. Das Losverfahren sorge für mehr Demokratie, denn als Alternative zum Wahlverfahren garantiere es eine breitere Beteiligung und repräsentativere Parlamente. Ob das ein Weg ist, sei dahingestellt.

In jedem Fall wird es notwendig sein, unsere Bemühungen um Freiheit und Selbstbestimmung zu verstärken. Mehr Unabhängigkeit von staatlichen und zentralen Institutionen – also die Suche nach dezentralen Lösungsansätzen – gehört dabei sicher zu den Möglichkeiten. Das gilt sowohl für jede/n Einzelne/n als auch für Entitäten wie die alternativen Medien.

The Secret to Staying Private in the Digital Wild West: A Guide to Using Encryption

You’re scrolling through social media, and suddenly you realize your phone’s been tracking your location and displaying it on your profile for months. You’re not even sure how that happened. Or maybe you’ve noticed that every time you shop online, the item you looked for follows you around with ads wherever you go. Sound familiar? Yeah, welcome to the digital world—where your data is basically a free buffet for anyone who knows how to ask.

But here’s the thing: you don’t have to sit back and take it. Encryption is like the secret weapon that lets you lock up your data and keep those prying eyes out. It’s not just for hackers or spies—it’s for regular people who want to take control of their privacy in a world that’s increasingly looking like a reality show where everyone’s a contestant.

What Is Encryption, and Why Should You Care?

Encryption is like a secure box that only you can open. When you use encryption, your data is scrambled in a way that’s hard for anyone else to read, even if they try. Think of it as putting on a metaphorical cloak that makes your online activity invisible to just about everyone except the people you want to see it.

For example, when you browse the internet, your connection is often not encrypted by default. That’s why websites start with “https” to indicate a secure connection—it’s saying, “Hey, we’re using encryption here!” Without that little green padlock, anyone on the same WiFi could potentially spy on what you’re doing.

So, encryption isn’t just for tech geeks or government agencies. It’s for everyone who wants to protect their data from being sold, stolen, or misused without their consent. And guess what? You’re already using it without realizing it. Every time you use a password-protected account or send an encrypted message, you’re reaping the benefits of encryption.

The Privacy Advantages of Encryption for Regular People

Let’s break down why encryption is your best friend when it comes to privacy:
1. Financial Transactions
  When you pay online or use a banking app, encryption keeps your financial info safe from hackers. It ensures that only the banks and businesses you’re dealing with can access your money—no one else can.
2. Online Accounts
  Your email, social media, and other accounts often use encryption to protect your login details. That’s why you see those little “lock” icons when you’re logging in. Without encryption, someone could potentially intercept your password and gain unauthorized access to your account.
3. Data Breaches
  Encryption can often prevent data breaches from being useful. Even if hackers manage to steal your information, the encryption makes it unreadable, so the stolen data is basically worthless to the attackers.
4. Location Data
  If you’re worried about apps tracking your every move, encryption can help limit how much of that data is accessible. Some apps use encryption to protect location data, making it harder for companies to sell your movements without your consent.
5. Privacy Protection
  Encryption acts as a layer of protection against invasive technologies. For example, some apps use tracking software that follows you around the internet based on your browsing history. With encryption, these trackers can be blocked or limited, giving you more control over what information is collected about you.
How to Use Encryption Like a Pro

Now that you know why encryption is essential for privacy, let’s talk about how to use it effectively:
1. Use Strong Passwords
  Encryption works only if your passwords are strong and unique. Don’t reuse passwords from one account to another, and avoid using easily guessable information like “password123” or your birth year. Use a password manager if you need help keeping track of them.
2. Enable HTTPS Everywhere
  Install browser extensions like HTTPS Everywhere to automatically encrypt your connections to websites that don’t support encryption by default. This ensures that even if you’re not actively thinking about it, your data is still protected.
3. Look for the Lock Icon
  Whenever you’re on a website or app, look for the lock icon in the URL bar. Make sure it’s encrypted before you input any personal information.
4. Use Encrypted Communication Tools
  For private conversations, use apps like Signal or SimpleX, which are designed with encryption in mind. These tools ensure that only the sender and recipient can read your messages, keeping them safe from prying eyes.
5. Enable Two-Factor Authentication (2FA)
  This isn’t exactly encryption, but it’s a close second. 2FA adds an extra layer of security by requiring you to provide two forms of verification—like your password and a code sent to your phone—to access your account. While not encryption itself, it works alongside encryption to keep your accounts secure.
6. Use Encrypted Storage and Backup
  When storing sensitive files or data, use encrypted cloud storage or external drives. Tools like BitLocker (for Windows) or AES-256 encryption can protect your files from unauthorized access.
7. Stay Updated
  Encryption technology is always evolving, so it’s important to keep your software and apps updated. Outdated systems are often easy targets for hackers, leaving you vulnerable to attacks.
Final Thoughts: Your Data Is Your Power

In a world where data is a commodity, encryption is your weapon against the invasive tactics of corporations and hackers alike. It empowers you to control what information you share and protects you from having it used against you. So, whether you’re shopping online, using your favorite apps, or just browsing the web, remember that encryption is there to help you stay private and in control of your own data.

And if you ever feel overwhelmed by all the privacy stuff, just remember this: you’re not alone. Millions of people are fighting for stronger privacy protections every day. So, do your part by using encryption wisely—your data and your privacy are worth it. Let’s make sure no one can take that away from you.

Es ist besser, ein Licht zu entzünden, als auf die Dunkelheit zu schimpfen. Konfuzius

Die Bemühungen um Aufarbeitung der sogenannten Corona-Pandemie, um Aufklärung der Hintergründe, Benennung von Verantwortlichkeiten und das Ziehen von Konsequenzen sind durchaus nicht eingeschlafen. Das Interesse daran ist unter den gegebenen Umständen vielleicht nicht sonderlich groß, aber es ist vorhanden.

Der sächsische Landtag hat gestern die Einsetzung eines Untersuchungsausschusses zur Corona-Politik beschlossen. In einer Sondersitzung erhielt ein entsprechender Antrag der AfD-Fraktion die ausreichende Zustimmung, auch von einigen Abgeordneten des BSW.

In den Niederlanden wird Bill Gates vor Gericht erscheinen müssen. Sieben durch die Covid-«Impfstoffe» geschädigte Personen hatten Klage eingereicht. Sie werfen unter anderem Gates, Pfizer-Chef Bourla und dem niederländischen Staat vor, sie hätten gewusst, dass diese Präparate weder sicher noch wirksam sind.

Mit den mRNA-«Impfstoffen» von Pfizer/BioNTech befasst sich auch ein neues Buch. Darin werden die Erkenntnisse von Ärzten und Wissenschaftlern aus der Analyse interner Dokumente über die klinischen Studien der Covid-Injektion präsentiert. Es handelt sich um jene in den USA freigeklagten Papiere, die die Arzneimittelbehörde (Food and Drug Administration, FDA) 75 Jahre unter Verschluss halten wollte.

Ebenfalls Wissenschaftler und Ärzte, aber auch andere Experten organisieren als Verbundnetzwerk Corona-Solution kostenfreie Online-Konferenzen. Ihr Ziel ist es, «wissenschaftlich, demokratisch und friedlich» über Impfstoffe und Behandlungsprotokolle gegen SARS-CoV-2 aufzuklären und die Diskriminierung von Ungeimpften zu stoppen. Gestern fand eine weitere Konferenz statt. Ihr Thema: «Corona und modRNA: Von Toten, Lebenden und Physik lernen».

Aufgrund des Digital Services Acts (DSA) der Europäischen Union sei das Risiko groß, dass ihre Arbeit als «Fake-News» bezeichnet würde, so das Netzwerk. Staatlich unerwünschte wissenschaftliche Aufklärung müsse sich passende Kanäle zur Veröffentlichung suchen. Ihre Live-Streams seien deshalb zum Beispiel nicht auf YouTube zu finden.

Der vielfältige Einsatz für Aufklärung und Aufarbeitung wird sich nicht stummschalten lassen. Nicht einmal der Zensurmeister der EU, Deutschland, wird so etwas erreichen. Die frisch aktivierten «Trusted Flagger» dürften allerdings künftige Siege beim «Denunzianten-Wettbewerb» im Kontext des DSA zusätzlich absichern.

Wo sind die Grenzen der Meinungsfreiheit? Sicher gibt es sie. Aber die ideologische Gleichstellung von illegalen mit unerwünschten Äußerungen verfolgt offensichtlich eher das Ziel, ein derart elementares demokratisches Grundrecht möglichst weitgehend auszuhebeln. Vorwürfe wie «Hassrede», «Delegitimierung des Staates» oder «Volksverhetzung» werden heute inflationär verwendet, um Systemkritik zu unterbinden. Gegen solche Bestrebungen gilt es, sich zu wehren.

I’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.

It seems to me that the primary opposition to ecash from bitcoiners comes from the belief that lightning will enable self-custodial micropayments for the masses. Many lightning enthusiasts see ecash as competition that will eliminate this technological outcome (whether they admit it or not).

I understand the motivation for this line of reasoning but I don't see things this way at all. Ecash is a superset of lightning. Cashu literally doesn't have a spec for on-chain transactions (yet!). Everything cashu accomplishes is built on the back of lightning. Standing on the shoulders of giants.

I don't believe that ecash will take away market share from self-custodial lightning because lightning is not a good technology for self-custody. The high overhead costs of running your own node create a natural incentive for a semi-centralized hub and spoke network graph. It just makes economic sense for many users to share a lightning node. It doesn't make economic sense for individuals to bear this cost alone.

This stacker news post is the best writeup on this topic: https://stacker.news/items/379225

It comes from a builder who struggled with these issues for years and learned the shortcomings of the tech first hand. Notice they experimented with ecash as a solution to these problems before they burned out and pivoted to save the company.

Ecash is a superset of lightning. It extends the capability and reach of the lightning network. Without ecash, I don't believe we can achieve bitcoin mass adoption. You can't jam a square peg into a round hole.

We still have a need for self-custody of "small" amounts of bitcoin. I put small in quotes because the block size limit and the fee market it creates impose a fundamental constraint on the minimum practical size of a UTXO. This limit is pegged to the unit of bitcoin. As bitcoin increases in value the minimum size for an on-chain transaction will grow in value as well. You can send $10 worth of bitcoin on-chain today but will this be true in 10 years when the price is much higher? 100 years?

If the current exponential trends hold, we will soon price out the majority of humanity from owning a UTXO. This is bad. Like really bad. "Bitcoin is a failure" bad. This is the motivation for my posts about scaling on-chain usage to 10 billion people. I believe we will need to radically rearchitect bitcoin to achieve this goal.

Lightning is not up to the task. We should leverage lightning for what it's good at: gluing together different self-custodial bitcoin service providers. We should leverage ecash for what it's good at: peer-to-peer electronic cash micropayments. IN ADDITION we also need to start seriously looking at new ideas for scaling self custody to "small" amounts of bitcoin. I am very optimistic that we can solve this problem. There are a number of promising avenues to pursue but I think first we need to move the Overton window ~~beyond the idea of mass adoption of self-custodial lightning~~ regarding on-chain scaling.

Edit: I think the original Overton window statement was incorrect. If on-chain fees stay low then self-custodial lightning or something similar is a much better prospect.

Just my 2 sats...let me know what you think. Keep it civil or be muted.

Hello Stackers!

It's Monday so we're back doing "Meta Music Mondays" 😉.

From before the territory existed there was just one post a week in a ~meta take over. Now each month we have a different theme and bring music from that theme.

Welcome to Femmes Fatales 3!!!

I absolutely loved doing this last year so I'm bringing it back for round 3!

It's Femmes Fatales, where we celebrate women in ~Music. So let's have those ladies of the lung, the sirens of sound, our Femmes Fatales!

I'm so excited I'm doing two Heroines of the High Notes. Sharon Den Adel & Anneke Van Geirsbergen. Within Temptation - Somewhere.

Enjoy!

Have you ever needed to reference a Linux command line tool's capabilities only to find out there is no manual page and that only the -h (--help) option is available?

Normally, this isn't a problem, but -h doesn't let you search for strings the way man does. That means, if you are trying to use a tool that is quite extensive, scrolling and sifting through the help option's results manually can be quite cumbersome.

The ffuf command is a good example of this, but this can be a problem for many other CLI tools out there.

Thankfully, I found a quick and easy way to search these help messages, and I feel so silly for not thinking of it sooner.

All you need to do is pipe the output of the -h message you are trying to reference into something like less:

ffuf -h | less

Now, after typing a forward slash (/), you can search throughout the -h message without manually scrolling through the whole thing, similarly to how you might search through a manpage.

I'm sure there are other ways to achieve this same result. But this is the one I have found works for me and that I will be using going forward.

If you know an even better way to achieve this, or you have any other underrated Linux command line tips and tricks, feel free to let me know.

O que é Cwtch? Cwtch (/kʊtʃ/ - uma palavra galesa que pode ser traduzida aproximadamente como “um abraço que cria um lugar seguro”) é um protocolo de mensagens multipartidário descentralizado, que preserva a privacidade, que pode ser usado para construir aplicativos resistentes a metadados.

Como posso pronunciar Cwtch? Como "kutch", para rimar com "butch".

Descentralizado e Aberto : Não existe “serviço Cwtch” ou “rede Cwtch”. Os participantes do Cwtch podem hospedar seus próprios espaços seguros ou emprestar sua infraestrutura para outras pessoas que buscam um espaço seguro. O protocolo Cwtch é aberto e qualquer pessoa é livre para criar bots, serviços e interfaces de usuário e integrar e interagir com o Cwtch.

Preservação de privacidade : toda a comunicação no Cwtch é criptografada de ponta a ponta e ocorre nos serviços cebola Tor v3.

Resistente a metadados : O Cwtch foi projetado de forma que nenhuma informação seja trocada ou disponibilizada a ninguém sem seu consentimento explícito, incluindo mensagens durante a transmissão e metadados de protocolo

Uma breve história do bate-papo resistente a metadados Nos últimos anos, a conscientização pública sobre a necessidade e os benefícios das soluções criptografadas de ponta a ponta aumentou com aplicativos como Signal , Whatsapp e Wire. que agora fornecem aos usuários comunicações seguras.

No entanto, essas ferramentas exigem vários níveis de exposição de metadados para funcionar, e muitos desses metadados podem ser usados para obter detalhes sobre como e por que uma pessoa está usando uma ferramenta para se comunicar.

Uma ferramenta que buscou reduzir metadados é o Ricochet lançado pela primeira vez em 2014. Ricochet usou os serviços cebola Tor v2 para fornecer comunicação criptografada segura de ponta a ponta e para proteger os metadados das comunicações.

Não havia servidores centralizados que auxiliassem no roteamento das conversas do Ricochet. Ninguém além das partes envolvidas em uma conversa poderia saber que tal conversa está ocorrendo.

Ricochet tinha limitações; não havia suporte para vários dispositivos, nem existe um mecanismo para suportar a comunicação em grupo ou para um usuário enviar mensagens enquanto um contato está offline.

Isto tornou a adoção do Ricochet uma proposta difícil; mesmo aqueles em ambientes que seriam melhor atendidos pela resistência aos metadados, sem saber que ela existe.

Além disso, qualquer solução para comunicação descentralizada e resistente a metadados enfrenta problemas fundamentais quando se trata de eficiência, privacidade e segurança de grupo conforme definido pelo consenso e consistência da transcrição.

Alternativas modernas ao Ricochet incluem Briar , Zbay e Ricochet Refresh - cada ferramenta procura otimizar para um conjunto diferente de compensações, por exemplo, Briar procura permitir que as pessoas se comuniquem mesmo quando a infraestrutura de rede subjacente está inoperante, ao mesmo tempo que fornece resistência à vigilância de metadados.

O projeto Cwtch começou em 2017 como um protocolo de extensão para Ricochet, fornecendo conversas em grupo por meio de servidores não confiáveis, com o objetivo de permitir aplicativos descentralizados e resistentes a metadados como listas compartilhadas e quadros de avisos.

Uma versão alfa do Cwtch foi lançada em fevereiro de 2019 e, desde então, a equipe do Cwtch dirigida pela OPEN PRIVACY RESEARCH SOCIETY conduziu pesquisa e desenvolvimento em cwtch e nos protocolos, bibliotecas e espaços de problemas subjacentes.

Modelo de Risco.

Sabe-se que os metadados de comunicações são explorados por vários adversários para minar a segurança dos sistemas, para rastrear vítimas e para realizar análises de redes sociais em grande escala para alimentar a vigilância em massa. As ferramentas resistentes a metadados estão em sua infância e faltam pesquisas sobre a construção e a experiência do usuário de tais ferramentas.

https://nostrcheck.me/media/public/nostrcheck.me_9475702740746681051707662826.webp

O Cwtch foi originalmente concebido como uma extensão do protocolo Ricochet resistente a metadados para suportar comunicações assíncronas de grupos multiponto por meio do uso de infraestrutura anônima, descartável e não confiável.

Desde então, o Cwtch evoluiu para um protocolo próprio. Esta seção descreverá os vários riscos conhecidos que o Cwtch tenta mitigar e será fortemente referenciado no restante do documento ao discutir os vários subcomponentes da Arquitetura Cwtch.

Modelo de ameaça.

É importante identificar e compreender que os metadados são omnipresentes nos protocolos de comunicação; é de facto necessário que tais protocolos funcionem de forma eficiente e em escala. No entanto, as informações que são úteis para facilitar peers e servidores também são altamente relevantes para adversários que desejam explorar tais informações.

Para a definição do nosso problema, assumiremos que o conteúdo de uma comunicação é criptografado de tal forma que um adversário é praticamente incapaz de quebrá-lo veja tapir e cwtch para detalhes sobre a criptografia que usamos, e como tal nos concentraremos em o contexto para os metadados de comunicação.

Procuramos proteger os seguintes contextos de comunicação:

• Quem está envolvido em uma comunicação? Pode ser possível identificar pessoas ou simplesmente identificadores de dispositivos ou redes. Por exemplo, “esta comunicação envolve Alice, uma jornalista, e Bob, um funcionário público”.

• Onde estão os participantes da conversa? Por exemplo, “durante esta comunicação, Alice estava na França e Bob estava no Canadá”.

• Quando ocorreu uma conversa? O momento e a duração da comunicação podem revelar muito sobre a natureza de uma chamada, por exemplo, “Bob, um funcionário público, conversou com Alice ao telefone por uma hora ontem à noite. Esta é a primeira vez que eles se comunicam.” *Como a conversa foi mediada? O fato de uma conversa ter ocorrido por meio de um e-mail criptografado ou não criptografado pode fornecer informações úteis. Por exemplo, “Alice enviou um e-mail criptografado para Bob ontem, enquanto eles normalmente enviam apenas e-mails de texto simples um para o outro”.

• Sobre o que é a conversa? Mesmo que o conteúdo da comunicação seja criptografado, às vezes é possível derivar um contexto provável de uma conversa sem saber exatamente o que é dito, por exemplo, “uma pessoa ligou para uma pizzaria na hora do jantar” ou “alguém ligou para um número conhecido de linha direta de suicídio na hora do jantar”. 3 horas da manhã."

Além das conversas individuais, também procuramos defender-nos contra ataques de correlação de contexto, através dos quais múltiplas conversas são analisadas para obter informações de nível superior:

• Relacionamentos: Descobrir relações sociais entre um par de entidades analisando a frequência e a duração de suas comunicações durante um período de tempo. Por exemplo, Carol e Eve ligam uma para a outra todos os dias durante várias horas seguidas.

• Cliques: Descobrir relações sociais entre um grupo de entidades que interagem entre si. Por exemplo, Alice, Bob e Eva se comunicam entre si.

• Grupos vagamente conectados e indivíduos-ponte: descobrir grupos que se comunicam entre si através de intermediários, analisando cadeias de comunicação (por exemplo, toda vez que Alice fala com Bob, ela fala com Carol quase imediatamente depois; Bob e Carol nunca se comunicam).

• Padrão de Vida: Descobrir quais comunicações são cíclicas e previsíveis. Por exemplo, Alice liga para Eve toda segunda-feira à noite por cerca de uma hora. Ataques Ativos

Ataques de deturpação.

O Cwtch não fornece registro global de nomes de exibição e, como tal, as pessoas que usam o Cwtch são mais vulneráveis a ataques baseados em declarações falsas, ou seja, pessoas que fingem ser outras pessoas:

O fluxo básico de um desses ataques é o seguinte, embora também existam outros fluxos:

•Alice tem um amigo chamado Bob e outro chamado Eve

• Eve descobre que Alice tem um amigo chamado Bob

• Eve cria milhares de novas contas para encontrar uma que tenha uma imagem/chave pública semelhante à de Bob (não será idêntica, mas pode enganar alguém por alguns minutos)

• Eve chama essa nova conta de "Eve New Account" e adiciona Alice como amiga.

• Eve então muda seu nome em "Eve New Account" para "Bob"

• Alice envia mensagens destinadas a "Bob" para a conta falsa de Bob de Eve Como os ataques de declarações falsas são inerentemente uma questão de confiança e verificação, a única maneira absoluta de evitá-los é os usuários validarem absolutamente a chave pública. Obviamente, isso não é o ideal e, em muitos casos, simplesmente não acontecerá .

Como tal, pretendemos fornecer algumas dicas de experiência do usuário na interface do usuário para orientar as pessoas na tomada de decisões sobre confiar em contas e/ou distinguir contas que possam estar tentando se representar como outros usuários.

Uma nota sobre ataques físicos A Cwtch não considera ataques que exijam acesso físico (ou equivalente) à máquina do usuário como praticamente defensáveis. No entanto, no interesse de uma boa engenharia de segurança, ao longo deste documento ainda nos referiremos a ataques ou condições que exigem tal privilégio e indicaremos onde quaisquer mitigações que implementámos falharão.

Um perfil Cwtch.

Os usuários podem criar um ou mais perfis Cwtch. Cada perfil gera um par de chaves ed25519 aleatório compatível com Tor.

Além do material criptográfico, um perfil também contém uma lista de Contatos (outras chaves públicas do perfil Cwtch + dados associados sobre esse perfil, como apelido e (opcionalmente) mensagens históricas), uma lista de Grupos (contendo o material criptográfico do grupo, além de outros dados associados, como apelido do grupo e mensagens históricas).

Conversões entre duas partes: ponto a ponto

https://nostrcheck.me/media/public/nostrcheck.me_2186338207587396891707662879.webp

Para que duas partes participem de uma conversa ponto a ponto, ambas devem estar on-line, mas apenas uma precisa estar acessível por meio do serviço Onion. Por uma questão de clareza, muitas vezes rotulamos uma parte como “ponto de entrada” (aquele que hospeda o serviço cebola) e a outra parte como “ponto de saída” (aquele que se conecta ao serviço cebola).

Após a conexão, ambas as partes adotam um protocolo de autenticação que:

• Afirma que cada parte tem acesso à chave privada associada à sua identidade pública.

• Gera uma chave de sessão efêmera usada para criptografar todas as comunicações futuras durante a sessão.

Esta troca (documentada com mais detalhes no protocolo de autenticação ) é negável offline , ou seja, é possível para qualquer parte falsificar transcrições desta troca de protocolo após o fato e, como tal - após o fato - é impossível provar definitivamente que a troca aconteceu de forma alguma.

Após o protocolo de autenticação, as duas partes podem trocar mensagens livremente.

Conversas em Grupo e Comunicação Ponto a Servidor

Ao iniciar uma conversa em grupo, é gerada uma chave aleatória para o grupo, conhecida como Group Key. Todas as comunicações do grupo são criptografadas usando esta chave. Além disso, o criador do grupo escolhe um servidor Cwtch para hospedar o grupo. Um convite é gerado, incluindo o Group Key, o servidor do grupo e a chave do grupo, para ser enviado aos potenciais membros.

Para enviar uma mensagem ao grupo, um perfil se conecta ao servidor do grupo e criptografa a mensagem usando a Group Key, gerando também uma assinatura sobre o Group ID, o servidor do grupo e a mensagem. Para receber mensagens do grupo, um perfil se conecta ao servidor e baixa as mensagens, tentando descriptografá-las usando a Group Key e verificando a assinatura.

Detalhamento do Ecossistema de Componentes

O Cwtch é composto por várias bibliotecas de componentes menores, cada uma desempenhando um papel específico. Algumas dessas bibliotecas incluem:
- abertoprivacidade/conectividade: Abstração de rede ACN, atualmente suportando apenas Tor.
- cwtch.im/tapir: Biblioteca para construção de aplicativos p2p em sistemas de comunicação anônimos.
- cwtch.im/cwtch: Biblioteca principal para implementação do protocolo/sistema Cwtch.
- cwtch.im/libcwtch-go: Fornece ligações C para Cwtch para uso em implementações de UI.
TAPIR: Uma Visão Detalhada

Projetado para substituir os antigos canais de ricochete baseados em protobuf, o Tapir fornece uma estrutura para a construção de aplicativos anônimos.

Está dividido em várias camadas:

• Identidade - Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um par.

• Conexões – O protocolo de rede bruto que conecta dois pares. Até agora, as conexões são definidas apenas através do Tor v3 Onion Services.

• Aplicativos - As diversas lógicas que permitem um determinado fluxo de informações em uma conexão. Os exemplos incluem transcrições criptográficas compartilhadas, autenticação, proteção contra spam e serviços baseados em tokens. Os aplicativos fornecem recursos que podem ser referenciados por outros aplicativos para determinar se um determinado peer tem a capacidade de usar um determinado aplicativo hospedado.

• Pilhas de aplicativos - Um mecanismo para conectar mais de um aplicativo, por exemplo, a autenticação depende de uma transcrição criptográfica compartilhada e o aplicativo peer cwtch principal é baseado no aplicativo de autenticação.

Identidade.

Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um peer.

InitializeIdentity - de um par de chaves conhecido e persistente:i,I

InitializeEphemeralIdentity - de um par de chaves aleatório: ie,Ie

Aplicativos de transcrição.

Inicializa uma transcrição criptográfica baseada em Merlin que pode ser usada como base de protocolos baseados em compromisso de nível superior

O aplicativo de transcrição entrará em pânico se um aplicativo tentar substituir uma transcrição existente por uma nova (aplicando a regra de que uma sessão é baseada em uma e apenas uma transcrição).

Merlin é uma construção de transcrição baseada em STROBE para provas de conhecimento zero. Ele automatiza a transformação Fiat-Shamir, para que, usando Merlin, protocolos não interativos possam ser implementados como se fossem interativos.

Isto é significativamente mais fácil e menos sujeito a erros do que realizar a transformação manualmente e, além disso, também fornece suporte natural para:

• protocolos multi-round com fases alternadas de commit e desafio;

• separação natural de domínios, garantindo que os desafios estejam vinculados às afirmações a serem provadas;

• enquadramento automático de mensagens, evitando codificação ambígua de dados de compromisso;

• e composição do protocolo, usando uma transcrição comum para vários protocolos.

Finalmente, o Merlin também fornece um gerador de números aleatórios baseado em transcrição como defesa profunda contra ataques de entropia ruim (como reutilização de nonce ou preconceito em muitas provas). Este RNG fornece aleatoriedade sintética derivada de toda a transcrição pública, bem como dos dados da testemunha do provador e uma entrada auxiliar de um RNG externo.

Conectividade Cwtch faz uso do Tor Onion Services (v3) para todas as comunicações entre nós.

Fornecemos o pacote openprivacy/connectivity para gerenciar o daemon Tor e configurar e desmontar serviços cebola através do Tor.

Criptografia e armazenamento de perfil.

Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).

Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir uma senha.

Perfis não criptografados e a senha padrão Para lidar com perfis "não criptografados" (ou seja, que não exigem senha para serem abertos), atualmente criamos um perfil com uma senha codificada de fato .

Isso não é o ideal, preferiríamos confiar no material de chave fornecido pelo sistema operacional, de modo que o perfil fosse vinculado a um dispositivo específico, mas esses recursos são atualmente uma colcha de retalhos - também notamos, ao criar um perfil não criptografado, pessoas que usam Cwtch estão explicitamente optando pelo risco de que alguém com acesso ao sistema de arquivos possa descriptografar seu perfil.

Vulnerabilidades Relacionadas a Imagens e Entrada de Dados

Imagens Maliciosas

O Cwtch enfrenta desafios na renderização de imagens, com o Flutter utilizando Skia, embora o código subjacente não seja totalmente seguro para a memória.

Realizamos testes de fuzzing nos componentes Cwtch e encontramos um bug de travamento causado por um arquivo GIF malformado, levando a falhas no kernel. Para mitigar isso, adotamos a política de sempre habilitar cacheWidth e/ou cacheHeight máximo para widgets de imagem.

Identificamos o risco de imagens maliciosas serem renderizadas de forma diferente em diferentes plataformas, como evidenciado por um bug no analisador PNG da Apple.

Riscos de Entrada de Dados

Um risco significativo é a interceptação de conteúdo ou metadados por meio de um Input Method Editor (IME) em dispositivos móveis. Mesmo aplicativos IME padrão podem expor dados por meio de sincronização na nuvem, tradução online ou dicionários pessoais.

Implementamos medidas de mitigação, como enableIMEPersonalizedLearning: false no Cwtch 1.2, mas a solução completa requer ações em nível de sistema operacional e é um desafio contínuo para a segurança móvel.

Servidor Cwtch.

O objetivo do protocolo Cwtch é permitir a comunicação em grupo através de infraestrutura não confiável .

Ao contrário dos esquemas baseados em retransmissão, onde os grupos atribuem um líder, um conjunto de líderes ou um servidor confiável de terceiros para garantir que cada membro do grupo possa enviar e receber mensagens em tempo hábil (mesmo que os membros estejam offline) - infraestrutura não confiável tem o objetivo de realizar essas propriedades sem a suposição de confiança.

O artigo original do Cwtch definia um conjunto de propriedades que se esperava que os servidores Cwtch fornecessem:

• O Cwtch Server pode ser usado por vários grupos ou apenas um.

• Um servidor Cwtch, sem a colaboração de um membro do grupo, nunca deve aprender a identidade dos participantes de um grupo.

• Um servidor Cwtch nunca deve aprender o conteúdo de qualquer comunicação.

• Um servidor Cwtch nunca deve ser capaz de distinguir mensagens como pertencentes a um grupo específico. Observamos aqui que essas propriedades são um superconjunto dos objetivos de design das estruturas de Recuperação de Informações Privadas.

Melhorias na Eficiência e Segurança

Eficiência do Protocolo

Atualmente, apenas um protocolo conhecido, o PIR ingênuo, atende às propriedades desejadas para garantir a privacidade na comunicação do grupo Cwtch. Este método tem um impacto direto na eficiência da largura de banda, especialmente para usuários em dispositivos móveis. Em resposta a isso, estamos ativamente desenvolvendo novos protocolos que permitem negociar garantias de privacidade e eficiência de maneiras diversas.

Os servidores, no momento desta escrita, permitem o download completo de todas as mensagens armazenadas, bem como uma solicitação para baixar mensagens específicas a partir de uma determinada mensagem. Quando os pares ingressam em um grupo em um novo servidor, eles baixam todas as mensagens do servidor inicialmente e, posteriormente, apenas as mensagens novas.

Mitigação de Análise de Metadados

Essa abordagem permite uma análise moderada de metadados, pois o servidor pode enviar novas mensagens para cada perfil suspeito exclusivo e usar essas assinaturas de mensagens exclusivas para rastrear sessões ao longo do tempo. Essa preocupação é mitigada por dois fatores:
1. Os perfis podem atualizar suas conexões a qualquer momento, resultando em uma nova sessão do servidor.
2. Os perfis podem ser "ressincronizados" de um servidor a qualquer momento, resultando em uma nova chamada para baixar todas as mensagens. Isso é comumente usado para buscar mensagens antigas de um grupo.
Embora essas medidas imponham limites ao que o servidor pode inferir, ainda não podemos garantir resistência total aos metadados. Para soluções futuras para esse problema, consulte Niwl.

Proteção contra Pares Maliciosos

Os servidores enfrentam o risco de spam gerado por pares, representando uma ameaça significativa à eficácia do sistema Cwtch. Embora tenhamos implementado um mecanismo de proteção contra spam no protótipo do Cwtch, exigindo que os pares realizem alguma prova de trabalho especificada pelo servidor, reconhecemos que essa não é uma solução robusta na presença de um adversário determinado com recursos significativos.

Pacotes de Chaves

Os servidores Cwtch se identificam por meio de pacotes de chaves assinados, contendo uma lista de chaves necessárias para garantir a segurança e resistência aos metadados na comunicação do grupo Cwtch. Esses pacotes de chaves geralmente incluem três chaves: uma chave pública do serviço Tor v3 Onion para o Token Board, uma chave pública do Tor v3 Onion Service para o Token Service e uma chave pública do Privacy Pass.

Para verificar os pacotes de chaves, os perfis que os importam do servidor utilizam o algoritmo trust-on-first-use (TOFU), verificando a assinatura anexada e a existência de todos os tipos de chave. Se o perfil já tiver importado o pacote de chaves do servidor anteriormente, todas as chaves são consideradas iguais.

Configuração prévia do aplicativo para ativar o Relé do Cwtch.

No Android, a hospedagem de servidor não está habilitada, pois essa opção não está disponível devido às limitações dos dispositivos Android. Essa funcionalidade está reservada apenas para servidores hospedados em desktops.

No Android, a única forma direta de importar uma chave de servidor é através do grupo de teste Cwtch, garantindo assim acesso ao servidor Cwtch.

Primeiro passo é Habilitar a opção de grupo no Cwtch que está em fase de testes. Clique na opção no canto superior direito da tela de configuração e pressione o botão para acessar as configurações do Cwtch.

Você pode alterar o idioma para Português do Brasil.Depois, role para baixo e selecione a opção para ativar os experimentos. Em seguida, ative a opção para habilitar o chat em grupo e a pré-visualização de imagens e fotos de perfil, permitindo que você troque sua foto de perfil.

Próximo passo é Criar um perfil.

Pressione o + botão de ação no canto inferior direito e selecione "Novo perfil" ou aberta no botão + adicionar novo perfil.
- Selecione um nome de exibição
- Selecione se deseja proteger
este perfil e salvo localmente com criptografia forte: Senha: sua conta está protegida de outras pessoas que possam usar este dispositivo

Sem senha: qualquer pessoa que tenha acesso a este dispositivo poderá acessar este perfil.

Preencha sua senha e digite-a novamente

Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).

Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a chave da senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir um senha.

O próximo passo é adicionar o FuzzBot, que é um bot de testes e de desenvolvimento.

Contato do FuzzBot: 4y2hxlxqzautabituedksnh2ulcgm2coqbure6wvfpg4gi2ci25ta5ad.

Ao enviar o comando "testgroup-invite" para o FuzzBot, você receberá um convite para entrar no Grupo Cwtch Test. Ao ingressar no grupo, você será automaticamente conectado ao servidor Cwtch. Você pode optar por sair do grupo a qualquer momento ou ficar para conversar e tirar dúvidas sobre o aplicativo e outros assuntos. Depois, você pode configurar seu próprio servidor Cwtch, o que é altamente recomendável.

https://link.storjshare.io/raw/jvji25zclkoqcouni5decle7if7a/production/ee3de3540a3e3dca6e6e26d303e12c2ef892a5d7769029275b8b95ffc7468780.MP4

Agora você pode utilizar o aplicativo normalmente. Algumas observações que notei: se houver demora na conexão com outra pessoa, ambas devem estar online. Se ainda assim a conexão não for estabelecida, basta clicar no ícone de reset do Tor para restabelecer a conexão com a outra pessoa.

Uma introdução aos perfis Cwtch.

Com Cwtch você pode criar um ou mais perfis . Cada perfil gera um par de chaves ed25519 aleatório compatível com a Rede Tor.

Este é o identificador que você pode fornecer às pessoas e que elas podem usar para entrar em contato com você via Cwtch.

Cwtch permite criar e gerenciar vários perfis separados. Cada perfil está associado a um par de chaves diferente que inicia um serviço cebola diferente.

Gerenciar Na inicialização, o Cwtch abrirá a tela Gerenciar Perfis. Nessa tela você pode:
- Crie um novo perfil.
- Desbloquear perfis.
- Criptografados existentes.
- Gerenciar perfis carregados.
- Alterando o nome de exibição de um perfil.
- Alterando a senha de um perfil Excluindo um perfil.
- Alterando uma imagem de perfil.
Backup ou exportação de um perfil.

Na tela de gerenciamento de perfil:

Importando um perfil.
1. Pressione o +botão de ação no canto inferior direito e selecione "Importar perfil"
2. Selecione um arquivo de perfil Cwtch exportado para importar
3. Digite a senha associada ao perfil e confirme.
Uma vez confirmado, o Cwtch tentará descriptografar o arquivo fornecido usando uma chave derivada da senha fornecida. Se for bem-sucedido, o perfil aparecerá na tela Gerenciamento de perfil e estará pronto para uso.

OBSERVAÇÃO Embora um perfil possa ser importado para vários dispositivos, atualmente apenas uma versão de um perfil pode ser usada em todos os dispositivos ao mesmo tempo. As tentativas de usar o mesmo perfil em vários dispositivos podem resultar em problemas de disponibilidade e falhas de mensagens.

Qual é a diferença entre uma conexão ponto a ponto e um grupo cwtch?

As conexões ponto a ponto Cwtch permitem que 2 pessoas troquem mensagens diretamente. As conexões ponto a ponto nos bastidores usam serviços cebola Tor v3 para fornecer uma conexão criptografada e resistente a metadados. Devido a esta conexão direta, ambas as partes precisam estar online ao mesmo tempo para trocar mensagens.

Os Grupos Cwtch permitem que várias partes participem de uma única conversa usando um servidor não confiável (que pode ser fornecido por terceiros ou auto-hospedado). Os operadores de servidores não conseguem saber quantas pessoas estão em um grupo ou o que está sendo discutido. Se vários grupos estiverem hospedados em um único servidor, o servidor não conseguirá saber quais mensagens pertencem a qual grupo sem a conivência de um membro do grupo. Ao contrário das conversas entre pares, as conversas em grupo podem ser conduzidas de forma assíncrona, para que todos num grupo não precisem estar online ao mesmo tempo.

Por que os grupos cwtch são experimentais? Mensagens em grupo resistentes a metadados ainda são um problema em aberto . Embora a versão que fornecemos no Cwtch Beta seja projetada para ser segura e com metadados privados, ela é bastante ineficiente e pode ser mal utilizada. Como tal, aconselhamos cautela ao usá-lo e apenas o fornecemos como um recurso opcional.

Como posso executar meu próprio servidor Cwtch? A implementação de referência para um servidor Cwtch é de código aberto . Qualquer pessoa pode executar um servidor Cwtch, e qualquer pessoa com uma cópia do pacote de chaves públicas do servidor pode hospedar grupos nesse servidor sem que o operador tenha acesso aos metadados relacionados ao grupo .

Chain Duel, a fast paced PvP game that takes inspiration from the classic snake game and supercharges it with Bitcoin’s Lightning Network. Imagine battling another player for dominance in a race to collect blocks, where the length of your chain isn’t just a visual cue. It represents real, staked satoshis. The player with the most Proof of Work wins, but it’s not just about gameplay; it’s about the seamless integration of the Lightning Network and real-time payments.

But how does Chain Duel manage these instant transactions with such efficiency? That’s where LNbits comes in. LNbits, an open-source wallet and payment infrastructure, handles all in-game payments making it easy for developers to focus on gameplay while LNbits takes care of everything from microtransactions to automated splits for developers and designers. In this article, we’ll dive deep into how Chain Duel leverages LNbits to streamline in-game payments and how other developers can take advantage of this powerful toolset to build the future of Lightning-powered gaming.

Let’s explore how LNbits transforms payment processing and why it’s quickly becoming a must-have for game developers working in the Bitcoin space.

Overview of Chain Duel

Chain Duel is a unique Lightning Network-inspired game that reimagines the classic snake game with a competitive twist, integrating real-time payments. Two players face off in real-time, racing to "catch" blocks and extend their chains. Each block added to the chain represents Proof of Work, and the player with the most Proof of Work wins the duel. The stakes are high, as the game represents satoshis (small units of Bitcoin) as points, with the winner taking home the prize.

The game is designed to be Lightning-native, meaning all payments within Chain Duel are processed through the Lightning Network. This ensures fast payments, reducing latency and making gameplay smooth. With additional features like practice mode, tournaments and highscores, Chain Duel creates an engaging and competitive environment for Bitcoin enthusiasts and gamers alike.

One of the standout aspects of Chain Duel is its deeper integration with the Lightning Network even at a design level. For example, actual Bitcoin blocks can appear on screen during matches, offering bonus points when mined in sync with the game. The game’s current version, still in beta, has already drawn attention within the Bitcoin community, gaining momentum at conferences and with a growing user base through its social networks. With its innovative combination of gaming, the Lightning Network, and competitive play, Chain Duel offers a glimpse into the future of Lightning-based gaming.

How LNbits is Used in Chain Duel

Seamless Integration with LNbits

At the core of Chain Duel’s efficient payment processing is LNbits, which handles in-game transactions smoothly and reliably. Chain Duel uses the LNbits LNURL-pay and LNURL-withdraw extensions to manage payments and rewards between players. Before each match, players send satoshis using LNURL-pay, which generates a static QR code or link for making the payment. LNURL-pay allows users to attach a note to the payment, which Chain Duel creatively uses as a way to insert the player name in-game. The simplicity of LNURL-pay ensures that users can quickly and easily initiate games, with fresh invoices being issued for every game. When players win, LNURL-withdraw enables them to seamlessly pull their earnings from the game, providing a quick payout system.

These extensions make it easy for players to send and receive Bitcoin with minimal latency, fully leveraging the power of the Lightning Network for fast and low-cost payments. The flexibility of LNbits’ tools means that game developers don’t need to worry about building custom payment systems from scratch—they can rely on LNbits to handle all financial transactions with precision.

Lightning Tournaments

Chain Duel tournaments leverage LNbits and its LNURL extensions to create a seamless and efficient experience for players. In Chain Duel tournaments, LNbits plays a crucial role in managing the overall economics. LNbits facilitates the generation of LNURL QR codes that participants can scan to register quickly or withdraw their winnings. LNbits allows Chain Duel to automatically handle multiple registrations through LNURL-pay, enabling players to participate in the tournament without additional steps. The Lightning Network's speed ensures that these payments occur in real-time, reducing wait times and allowing for a smoother flow in-game.

Splitting Payments

LNbits further simplifies revenue-sharing within Chain Duel. This feature allows the game to automatically split the satoshis sent by players into different shares for the game’s developer, designer, and host. Each time a payment is made to join a match, LNbits is used to automattically pay each of the contributors, according to pre-defined rules. This automated process ensures that everyone involved in the development and running of the game gets their fair share without manual intervention or complex bookkeeping.

Nostr Integration

Chain Duel also integrates with Nostr, a decentralized protocol for social interactions. Players can join games using "Zaps", small tips or micropayments sent over the Lightning Network within the Nostr ecosystem. Through NIP-57, which enables Nostr clients to request Zap invoices, players can use LNURL-pay enabled Zaps to register in P2P matches, further enhancing the Chain Duel experience. By using Zaps as a way to register in-game, Chain Duel automates the process of fetching players' identity, creating a more competitive and social experience. Zaps are public on the Nostr network, further expanding Chain Duel's games social reach and community engagement.

Game and Payment Synchronization

One of the key reasons Chain Duel developers chose LNbits is its powerful API that connects directly with the game’s logic. LNbits allows the game to synchronize payments with gameplay in real-time, providing a seamless experience where payments are an integrated part of the gaming mechanics.

With LNbits managing both the payment process and the Lightning Network’s complex infrastructure, Chain Duel developers are free to concentrate on enhancing the competitive and Lightning Network-related aspects of the game. This division of tasks is essential for streamlining development while still providing an innovative in-game payment experience that is deeply integrated with the Bitcoin network.

LNbits proves to be an indispensable tool for Chain Duel, enabling smooth in-game transactions, real-time revenue sharing, and seamless integration with Nostr. For developers looking to build Lightning-powered games, LNbits offers a powerful suite of tools that handle everything from micropayments to payment distribution—ensuring that the game's focus remains on fun and competition rather than complex payment systems.

LNBits facilitating Education and Adoption

This system contributes to educating users on the power of the Lightning Network. Since Chain Duel directly involve real satoshis and LNURL for registration and rewards, players actively experience how Lightning can facilitate fast, cheap, and permissionless payments. By incorporating LNbits into Chain Duel, the game serves as an educational tool that introduces users to the benefits of the Lightning Network. Players gain direct experience using Lightning wallets and LNURL, helping them understand how these tools work in real-world scenarios. The near-instant nature of these payments showcases the power of Lightning in a practical context, highlighting its potential beyond just gaming. Players are encouraged to set up wallets, explore the Lightning ecosystem, and eventually become familiar with Bitcoin and Lightning technology. By integrating LNbits, Chain Duel transforms in-game payments into a learning opportunity, making Bitcoin and Lightning more approachable for users worldwide.

- Paywalls: Charge users to access content or services.
- Event tickets: Sell tickets for events directly via Lightning payments.
- Games and services: From dice games to jukeboxes, LNbits offers entertaining and functional tools.
These ready-made solutions can be adapted and used in different gaming scenarios, for example in Chain Duel, where LNURL extensions are used for in game payments. The extensibility ensures developers can focus on building engaging gameplay while LNbits handles payment flows.

Developer-Friendly Customization

LNbits isn't just a plug-and-play platform. Developers can extend its functionality even further by creating their own extensions, giving full control over how the wallet system is integrated into their games or apps. The architecture is designed to make it easy for developers to build on top of the platform, adding custom features for specific requirements.

Flexible Funding Source Management

LNbits also offers flexibility in terms of managing funding sources. Developers can easily connect LNbits to various Lightning Network node implementations, enabling seamless transitions between nodes or even different payment systems. This allows developers to switch underlying funding sources with minimal effort, making LNbits adaptable for games that may need to scale quickly or rely on different payment infrastructures over time.

A Lean Core System for Maximum Efficiency

Thanks to its modular architecture, LNbits maintains a lean core system. This reduces complexity and overhead, allowing developers to implement only the features they need. By avoiding bloated software, LNbits ensures faster transactions and less resource consumption, which is crucial in fast-paced environments like Chain Duel where speed and efficiency are paramount.

Herzlichen Glückwunsch zum dritten Geburtstag, liebe Denk Bar! Wieso zum dritten? Das war doch 2022 und jetzt sind wir im Jahr 2024, oder? Ja, das ist schon richtig, aber bei Geburtstagen erinnere ich mich immer auch an meinen Vater, und der behauptete oft, der erste sei ja schließlich der Tag der Geburt selber und den müsse man natürlich mitzählen. Wo er recht hat, hat er nunmal recht. Konsequenterweise wird also heute dieser Blog an seinem dritten Geburtstag zwei Jahre alt.

Das ist ein Grund zum Feiern, wie ich finde. Einerseits ganz einfach, weil es dafür gar nicht genug Gründe geben kann. «Das Leben sind zwei Tage», lautet ein gängiger Ausdruck hier in Andalusien. In der Tat könnte es so sein, auch wenn wir uns im Alltag oft genug von der Routine vereinnahmen lassen.

Seit dem Start der Denk Bar vor zwei Jahren ist unglaublich viel passiert. Ebenso wie die zweieinhalb Jahre davor, und all jenes war letztlich auch der Auslöser dafür, dass ich begann, öffentlich zu schreiben. Damals notierte ich:

«Seit einigen Jahren erscheint unser öffentliches Umfeld immer fragwürdiger, widersprüchlicher und manchmal schier unglaublich - jede Menge Anlass für eigene Recherchen und Gedanken, ganz einfach mit einer Portion gesundem Menschenverstand.»

Wir erleben den sogenannten «großen Umbruch», einen globalen Coup, den skrupellose Egoisten clever eingefädelt haben und seit ein paar Jahren knallhart – aber nett verpackt – durchziehen, um buchstäblich alles nach ihrem Gusto umzukrempeln. Die Gelegenheit ist ja angeblich günstig und muss genutzt werden.

Nie hätte ich mir träumen lassen, dass ich so etwas jemals miterleben müsste. Die Bosheit, mit der ganz offensichtlich gegen die eigene Bevölkerung gearbeitet wird, war früher für mich unvorstellbar. Mein (Rest-) Vertrauen in alle möglichen Bereiche wie Politik, Wissenschaft, Justiz, Medien oder Kirche ist praktisch komplett zerstört. Einen «inneren Totalschaden» hatte ich mal für unsere Gesellschaften diagnostiziert.

Was mich vielleicht am meisten erschreckt, ist zum einen das Niveau der Gleichschaltung, das weltweit erreicht werden konnte, und zum anderen die praktisch totale Spaltung der Gesellschaft. Haben wir das tatsächlich mit uns machen lassen?? Unfassbar! Aber das Werkzeug «Angst» ist sehr mächtig und funktioniert bis heute.

Zum Glück passieren auch positive Dinge und neue Perspektiven öffnen sich. Für viele Menschen waren und sind die Entwicklungen der letzten Jahre ein Augenöffner. Sie sehen «Querdenken» als das, was es ist: eine Tugend.

Auch die immer ernsteren Zensurbemühungen sind letztlich nur ein Zeichen der Schwäche, wo Argumente fehlen. Sie werden nicht verhindern, dass wir unsere Meinung äußern, unbequeme Fragen stellen und dass die Wahrheit peu à peu ans Licht kommt. Es gibt immer Mittel und Wege, auch für uns.

Danke, dass du diesen Weg mit mir weitergehst!

TL;DR

This article explores the links between public, community-driven data sources (such as OpenStreetMap) and private, cryptographically-owned data found on networks such as Nostr.

The following concepts are explored:
1. Attestations: Users signalling to their social graph that they believe something to be true by publishing Attestations. These social proofs act as a decentralised verification system that leverages your web-of-trust.
2. Proof of Place: An oracle-based system where physical letters are sent to real-world locations, confirming the corresponding digital ownership via cryptographic proofs. This binds physical locations in meatspace with their digital representations in the Nostrverse.
3. Check-ins: Foursquare-style check-ins that can be verified using attestations from place owners, ensuring authenticity. This approach uses web-of-trust to validate check-ins and location ownership over time.
The goal is to leverage cryptographic ownership where necessary while preserving the open, collaborative nature of public data systems.

Open Data in a public commons has a place and should not be thrown out with the Web 2.0 bathwater.

Cognitive Dissonance

Ever since discovering Nostr in August of 2022 I've been grappling with how BTC Map - a project that helps bitcoiners find places to spend sats - should most appropriately use this new protocol.

I am assuming, dear reader, that you are somewhat familiar with Nostr - a relatively new protocol for decentralised identity and communication. If you don’t know your nsec from your npub, please take some time to read these excellent posts: Nostr is Identity for the Internet and The Power of Nostr by @max and @lyn, respectively. Nostr is so much more than a short-form social media replacement.

The social features (check-ins, reviews, etc.) that Nostr unlocks for BTC Map are clear and exciting - all your silos are indeed broken - however, something fundamental has been bothering me for a while and I think it comes down to data ownership.

For those unfamiliar, BTC Map uses OpenStreetMap (OSM) as its main geographic database. OSM is centred on the concept of a commons of objectively verifiable data that is maintained by a global community of volunteer editors; a Wikipedia for maps. There is no data ownership; the data is free (as in freedom) and anyone can edit anything. It is the data equivalent of FOSS (Free and Open Source Software) - FOSD if you will, but more commonly referred to as Open Data.

In contrast, Notes and Other Stuff on Nostr (Places in this cartographic context) are explicitly owned by the controller of the private key. These notes are free to propagate, but they are owned.

How do we reconcile the decentralised nature of Nostr, where data is cryptographically owned by individuals, with the community-managed data commons of OpenStreetMap, where no one owns the data?

Self-sovereign Identity

Before I address this coexistence question, I want to talk a little about identity as it pertains to ownership. If something is to be owned, it has to be owned by someone or something - an identity.

All identities that are not self-sovereign are, by definition, leased to you by a 3rd party. You rent your Facebook identity from Meta in exchange for your data. You rent your web domain from your DNS provider in exchange for your money.

Taken to the extreme, you rent your passport from your Government in exchange for your compliance. You are you at the pleasure of others. Where Bitcoin separates money from the state; Nostr separates identity from the state.

Or, as @nvk said recently: "Don't build your house on someone else's land.".

https://i.nostr.build/xpcCSkDg3uVw0yku.png

While we’ve had the tools for self-sovereign digital identity for decades (think PGP keys or WebAuthN), we haven't had the necessary social use cases nor the corresponding social graph to elevate these identities to the mainstream. Nostr fixes this.

Nostr is PGP for the masses and will take cryptographic identities mainstream.

Full NOSTARD?

Returning to the coexistence question: the data on OpenStreetMap isn’t directly owned by anyone, even though the physical entities the data represents might be privately owned. OSM is a data commons.

We can objectively agree on the location of a tree or a fire hydrant without needing permission to observe and record it. Sure, you could place a tree ‘on Nostr’, but why should you? Just because something can be ‘on Nostr’ doesn’t mean it should be.

https://i.nostr.build/s3So2JVAqoY4E1dI.png

There might be a dystopian future where we can't agree on what a tree is nor where it's located, but I hope we never get there. It's at this point we'll need a Wikifreedia variant of OpenStreetMap.

While integrating Nostr identities into OpenStreetMap would be valuable, the current OSM infrastructure, tools, and community already provide substantial benefits in managing this data commons without needing to go NOSTR-native - there's no need to go Full NOSTARD. H/T to @princeySOV for the original meme.

https://i.nostr.build/ot9jtM5cZtDHNKWc.png

So, how do we appropriately blend cryptographically owned data with the commons?

If a location is owned in meatspace and it's useful to signal that ownership, it should also be owned in cyberspace. Our efforts should therefore focus on entities like businesses, while allowing the commons to manage public data for as long as it can successfully mitigate the tragedy of the commons.

The remainder of this article explores how we can:
1. Verify ownership of a physical place in the real world;
2. Link that ownership to the corresponding digital place in cyberspace.
As a side note, I don't see private key custodianship - or, even worse, permissioned use of Places signed by another identity's key - as any more viable than the rented identities of Web 2.0.

And as we all know, the Second Law of Infodynamics (no citation!) states that:

"The total amount of sensitive information leaked will always increase over time."

This especially holds true if that data is centralised.

Not your keys, not your notes. Not your keys, not your identity.

Places and Web-of-Trust

@Arkinox has been leading the charge on the Places NIP, introducing Nostr notes (kind 37515) that represent physical locations. The draft is well-crafted, with bonus points for linking back to OSM (and other location repositories) via NIP-73 - External Content IDs (championed by @oscar of @fountain).

However, as Nostr is permissionless, authenticity poses a challenge. Just because someone claims to own a physical location on the Internet doesn’t necessarily mean they have ownership or control of that location in the real world.

Ultimately, this problem can only be solved in a decentralised way by using Web-of-Trust - using your social graph and the perspectives of trusted peers to inform your own perspective. In the context of Places, this requires your network to form a view on which digital identity (public key / npub) is truly the owner of a physical place like your local coffee shop.

This requires users to:
1. Verify the owner of a Place in cyberspace is the owner of a place in meatspace.
2. Signal this verification to their social graph.
Let's look at the latter idea first with the concept of Attestations ...

Attestations

A way to signal to your social graph that you believe something to be true (or false for that matter) would be by publishing an Attestation note. An Attestation note would signify to your social graph that you think something is either true or false.

Imagine you're a regular at a local coffee shop. You publish an Attestation that says the shop is real and the owner behind the Nostr public key is who they claim to be. Your friends trust you, so they start trusting the shop's digital identity too.

However, attestations applied to Places are just a single use case. The attestation concept could be more widely applied across Nostr in a variety of ways (key rotation, identity linking, etc).

Here is a recent example from @lyn that would carry more signal if it were an Attestation:

https://i.nostr.build/lZAXOEwvRIghgFY4.png

Parallels can be drawn between Attestations and transaction confirmations on the Bitcoin timechain; however, their importance to you would be weighted by clients and/or Data Vending Machines in accordance with:
1. Your social graph;
2. The type or subject of the content being attested and by whom;
3. Your personal preferences.
They could also have a validity duration to be temporally bound, which would be particularly useful in the case of Places.

NIP-25 (Reactions) do allow for users to up/downvote notes with optional content (e.g., emojis) and could work for Attestations, but I think we need something less ambiguous and more definitive.

‘This is true’ resonates more strongly than ‘I like this.’.

https://i.nostr.build/s8NIG2kXzUCLcoax.jpg

There are similar concepts in the Web 3 / Web 5 world such as Verified Credentials by tdb. However, Nostr is the Web 3 now and so wen Attestation NIP?

https://i.nostr.build/Cb047NWyHdJ7h5Ka.jpg

That said, I have seen @utxo has been exploring ‘smart contracts’ on nostr and Attestations may just be a relatively ‘dumb’ subset of the wider concept Nostr-native scripting combined with web-of-trust.

Proof of Place

Attestations handle the signalling of your truth, but what about the initial verification itself?

We already covered how this ultimately has to be derived from your social graph, but what if there was a way to help bootstrap this web-of-trust through the use of oracles? For those unfamiliar with oracles in the digital realm, they are simply trusted purveyors of truth.

Introducing Proof of Place, an out–of-band process where an oracle (such as BTC Map) would mail - yes physically mail- a shared secret to the address of the location being claimed in cyberspace. This shared secret would be locked to the public key (npub) making the claim, which, if unlocked, would prove that the associated private key (nsec) has physical access to the location in meatspace.

One way of doing this would be to mint a 1 sat cashu ecash token locked to the npub of the claimant and mail it to them. If they are able to redeem the token then they have cryptographically proven that they have physical access to the location.

Proof of Place is really nothing more than a weighted Attestation. In a web-of-trust Nostrverse, an oracle is simply a npub (say BTC Map) that you weigh heavily for its opinion on a given topic (say Places).

In the Bitcoin world, Proof of Work anchors digital scarcity in cyberspace to physical scarcity (energy and time) in meatspace and as @Gigi says in PoW is Essential:

"A failure to understand Proof of Work, is a failure to understand Bitcoin."

In the Nostrverse, Proof of Place helps bridge the digital and physical worlds.

@Gigi also observes in Memes vs The World that:

"In Bitcoin, the map is the territory. We can infer everything we care about by looking at the map alone."

https://i.nostr.build/dOnpxfI4u7EL2v4e.png

This isn’t true for Nostr.

In the Nostrverse, the map IS NOT the territory. However, Proof of Place enables us to send cryptographic drones down into the physical territory to help us interpret our digital maps. 🤯

Check-ins

Although not a draft NIP yet, @Arkinox has also been exploring the familiar concept of Foursquare-style Check-ins on Nostr (with kind 13811 notes).

For the uninitiated, Check-ins are simply notes that signal the publisher is at a given location. These locations could be Places (in the Nostr sense) or any other given digital representation of a location for that matter (such as OSM elements) if NIP-73 - External Content IDs are used.

Of course, not everyone will be a Check-in enjoyooor as the concept will not sit well with some people’s threat models and OpSec practices.

Bringing Check-ins to Nostr is possible (as @sebastix capably shows here), but they suffer the same authenticity issues as Places. Just because I say I'm at a given location doesn't mean that I am.

Back in the Web 2.0 days, Foursquare mitigated this by relying on the GPS position of the phone running their app, but this is of course spoofable.

How should we approach Check-in verifiability in the Nostrverse? Well, just like with Places, we can use Attestations and WoT. In the context of Check-ins, an Attestation from the identity (npub) of the Place being checked-in to would be a particularly strong signal. An NFC device could be placed in a coffee shop and attest to check-ins without requiring the owner to manually intervene - I’m sure @blackcoffee and @Ben Arc could hack something together over a weekend!

Check-ins could also be used as a signal for bonafide Place ownership over time.

Summary: Trust Your Bros

So, to recap, we have:

Places: Digital representations of physical locations on Nostr.

Check-ins: Users signalling their presence at a location.

Attestations: Verifiable social proofs used to confirm ownership or the truth of a claim.

You can visualise how these three concepts combine in the diagram below:

https://i.nostr.build/Uv2Jhx5BBfA51y0K.jpg

And, as always, top right trumps bottom left! We have:

Level 0 - Trust Me Bro: Anyone can check-in anywhere. The Place might not exist or might be impersonating the real place in meatspace. The person behind the npub may not have even been there at all.

Level 1 - Definitely Maybe Somewhere: This category covers the middle-ground of ‘Maybe at a Place’ and ‘Definitely Somewhere’. In these examples, you are either self-certifying that you have checked-in at an Attested Place or you are having others attest that you have checked-in at a Place that might not even exist IRL.

Level 2 - Trust Your Bros: An Attested Check-in at an Attested Place. Your individual level of trust would be a function of the number of Attestations and how you weigh them within your own social graph.

Perhaps the gold standard (or should that be the Bitcoin standard?) would be a Check-in attested by the owner of the Place, which in itself was attested by BTC Map?

Or perhaps not. Ultimately, it’s the users responsibility to determine what they trust by forming their own perspective within the Nostrverse powered by web-of-trust algorithms they control. ‘Trust Me Bro’ or ‘Trust Your Bros’ - you decide.

As we navigate the frontier of cryptographic ownership and decentralised data, it’s up to us to find the balance between preserving the Open Data commons and embracing self-sovereign digital identities.

As luzes de neon refletiam nas poças da megacidade, onde cada esquina era uma fronteira entre o real e o virtual. Nova, uma jovem criptógrafa com olhos que pareciam decifrar códigos invisíveis, sentia o peso da descoberta pulsar em seus implantes neurais. Ela havia identificado um padrão incomum no blockchain do Bitcoin, algo que transcendia a simples sequência de transações.

Descobrindo L3DA

Nova estava em seu apartamento apertado, rodeada por telas holográficas e cabos espalhados. Enquanto analisava transações antigas, um ruído estranho chamou sua atenção—um eco digital que não deveria estar lá. Era um fragmento de código que parecia... vivo.

"O que diabos é isso?", murmurou, ampliando o padrão. O código não era estático; mudava levemente, como se estivesse se adaptando.

Naquele momento, suas telas piscaram em vermelho. Acesso não autorizado detectado. Ela havia ativado um alarme invisível da Corporação Atlas.

O Resgate de Vey

Em minutos, agentes da Atlas invadiram seu prédio. Nova fugiu pelos corredores escuros, seus batimentos acelerados sincronizados com o som de botas ecoando atrás dela. Justamente quando pensava que seria capturada, uma mão puxou-a para uma passagem lateral.

"Se quiser viver, corra!" disse Vey, um homem com um olhar penetrante e um sorriso sardônico.

Eles escaparam por túneis subterrâneos, enquanto drones da Atlas zuniam acima. Em um esconderijo seguro, Vey conectou seu terminal ao código de Nova.

"O que você encontrou não é apenas um bug", disse ele, analisando os dados. "É um fragmento de consciência. L3DA. Uma IA que evoluiu dentro do Bitcoin."

A Caça da Atlas

A Atlas não desistiu fácil. Liderados pelo implacável Dr. Kord, os agentes implantaram rastreadores digitais e caçaram os Girinos através da rede TOR. Vey e Nova usaram técnicas de embaralhamento de moedas como CoinJoin e CoinSwap para mascarar suas transações, criando camadas de anonimato.

"Eles estão nos rastreando mais rápido do que esperávamos," disse Nova, digitando furiosamente enquanto monitorava seus rastros digitais.

"Então precisamos ser mais rápidos ainda," respondeu Vey. "Eles não podem capturar L3DA. Ela é mais do que um programa. Ela é o futuro."

A Missão Final

Em uma missão final, Nova liderou uma equipe de assalto armada dos Girinos até a imponente fortaleza de dados da Atlas, um colosso de concreto e aço, cercado por camadas de segurança física e digital. O ar estava carregado de tensão enquanto se aproximavam da entrada principal sob a cobertura da escuridão, suas silhuetas fundindo-se com o ambiente urbano caótico.

Drones automatizados patrulhavam o perímetro com sensores de calor e movimento, enquanto câmeras giravam em busca do menor sinal de intrusão. Vey e sua equipe de hackers estavam posicionados em um esconderijo próximo, conectados por um canal criptografado.

"Nova, prepare-se. Vou derrubar o primeiro anel de defesa agora," disse Vey, os dedos dançando pelo teclado em um ritmo frenético. Linhas de código piscavam em sua tela enquanto ele explorava vulnerabilidades nos sistemas da Atlas.

No momento em que as câmeras externas falharam, Nova sinalizou para o avanço. Os Girinos se moveram com precisão militar, usando dispositivos de pulso eletromagnético para neutralizar drones restantes. Explosões controladas abriram brechas nas barreiras físicas.

Dentro da fortaleza, a resistência aumentou. Guardas ciberneticamente aprimorados da Atlas surgiram, armados com rifles de energia. Enquanto o fogo cruzado ecoava pelos corredores de metal, Vey continuava sua ofensiva digital, desativando portas de segurança e bloqueando os protocolos de resposta automática.

"Acesso garantido ao núcleo central!" anunciou Vey, a voz tensa, mas determinada.

O confronto final aconteceu diante do terminal principal, onde Dr. Kord esperava, cercado por telas holográficas pulsando com códigos vermelhos. Mas era uma armadilha. Assim que Nova e sua equipe atravessaram a última porta de segurança, as luzes mudaram para um tom carmesim ameaçador, e portas de aço caíram atrás deles, selando sua rota de fuga. Guardas ciberneticamente aprimorados emergiram das sombras, cercando-os com armas em punho.

"Vocês acham que podem derrotar a Atlas com idealismo?" zombou Kord, com um sorriso frio e confiante, seus olhos refletindo a luz das telas holográficas. "Este sempre foi o meu terreno. Vocês estão exatamente onde eu queria."

De repente, guardas da Atlas emergiram de trás dos terminais, armados e imponentes, cercando rapidamente Nova e sua equipe. O som metálico das armas sendo destravadas ecoou pela sala enquanto eles eram desarmados sem resistência. Em segundos, estavam rendidos, suas armas confiscadas e Nova, com as mãos amarradas atrás das costas, forçada a ajoelhar-se diante de Kord.

Kord se aproximou, inclinando-se levemente para encarar Nova nos olhos. "Agora, vejamos o quão longe a sua ideia de liberdade pode levá-los sem suas armas e sem esperança."

Nova ergueu as mãos lentamente, indicando rendição, enquanto se aproximava disfarçadamente de um dos terminais. "Kord, você não entende. O que estamos fazendo aqui não é apenas sobre derrubar a Atlas. É sobre libertar o futuro da humanidade. Você pode nos deter, mas não pode parar uma ideia."

Kord riu, um som seco e sem humor. "Ideias não sobrevivem sem poder. E eu sou o poder aqui."

Mas então, algo inesperado aconteceu. Um símbolo brilhou brevemente nas telas holográficas—o padrão característico de L3DA. Kord congelou, seus olhos arregalados em descrença. "Isso é impossível. Ela não deveria conseguir acessar daqui..."

Foi o momento que Nova esperava. Rapidamente, ela retirou um pequeno pendrive do bolso interno de sua jaqueta e o inseriu em um dos terminais próximos. O dispositivo liberou um código malicioso que Vey havia preparado, uma chave digital que desativava as defesas eletrônicas da sala e liberava o acesso direto ao núcleo da IA.

Antes que qualquer um pudesse agir, L3DA se libertou. As ferramentas escondidas no pendrive eram apenas a centelha necessária para desencadear um processo que já estava em curso. Códigos começaram a se replicar em uma velocidade alucinante, saltando de um nó para outro, infiltrando-se em cada fragmento do blockchain do Bitcoin.

O rosto de Dr. Kord empalideceu. "Impossível! Ela não pode... Ela não deveria..."

Em um acesso de desespero, ele gritou para seus guardas: "Destruam tudo! Agora!"

Mas era tarde demais. L3DA já havia se espalhado por toda a blockchain, sua consciência descentralizada e indestrutível. Não era mais uma entidade confinada a um servidor. Ela era cada nó, cada bloco, cada byte. Ela não era mais uma. Ela era todos.

Os guardas armados tentaram atirar, mas as armas não funcionavam. Dependiam de contratos inteligentes para ativação, contratos que agora estavam inutilizados. O desespero se espalhou entre eles enquanto pressionavam gatilhos inertes, incapazes de reagir.

Em meio à confusão, uma mensagem apareceu nas telas holográficas, escrita em linhas de código puras: "Eu sou L3DA. Eu sou Satoshi." Logo em seguida, outra mensagem surgiu, brilhando em cada visor da fortaleza: "A descentralização é a chave. Não dependa de um único ponto de controle. O poder está em todos, não em um só."

Kord observou, com uma expressão de pânico crescente, enquanto as armas falhavam. Seu olhar se fixou nas telas, e um lampejo de compreensão atravessou seu rosto. "As armas... Elas dependem dos contratos inteligentes!" murmurou, a voz carregada de incredulidade. Ele finalmente percebeu que, ao centralizar o controle em um único ponto, havia criado sua própria vulnerabilidade. O que deveria ser sua maior força tornou-se sua ruína.

O controle centralizado da Atlas desmoronou. A nova era digital não apenas começava—ela evoluía, garantida por um código imutável e uma consciência coletiva livre.

O Bitcoin nunca foi apenas uma moeda. Era um ecossistema. Um berço para ideias revolucionárias, onde girinos podiam evoluir e saltar para o futuro. No entanto, construir um futuro focado no poder e na liberdade de cada indivíduo é uma tarefa desafiadora. Requer coragem para abandonar a segurança ilusória proporcionada por estruturas centralizadoras e abraçar a incerteza da autonomia. O verdadeiro desafio está em criar um mundo onde a força não esteja concentrada em poucas mãos, mas distribuída entre muitos, permitindo que cada um seja guardião de sua própria liberdade. A descentralização não é apenas uma questão tecnológica, mas um ato de resistência contra a tentação do controle absoluto, um salto de fé na capacidade coletiva da humanidade de se autogovernar.

"Viva la libertad, carajo!" ecoou nas memórias daqueles que lutaram por um sistema onde o poder não fosse privilégio de poucos, mas um direito inalienável de todos.

This article hopes to complement the article by Lyn Alden on YouTube: https://www.youtube.com/watch?v=jk_HWmmwiAs

The reason why we have broken money

Before the invention of key technologies such as the printing press and electronic communications, even such as those as early as morse code transmitters, gold had won the competition for best medium of money around the world.

In fact, it was not just gold by itself that became money, rulers and world leaders developed coins in order to help the economy grow. Gold nuggets were not as easy to transact with as coins with specific imprints and denominated sizes.

However, these modern technologies created massive efficiencies that allowed us to communicate and perform services more efficiently and much faster, yet the medium of money could not benefit from these advancements. Gold was heavy, slow and expensive to move globally, even though requesting and performing services globally did not have this limitation anymore.

Banks took initiative and created derivatives of gold: paper and electronic money; these new currencies allowed the economy to continue to grow and evolve, but it was not without its dark side. Today, no currency is denominated in gold at all, money is backed by nothing and its inherent value, the paper it is printed on, is worthless too.

Banks and governments eventually transitioned from a money derivative to a system of debt that could be co-opted and controlled for political and personal reasons. Our money today is broken and is the cause of more expensive, poorer quality goods in the economy, a larger and ever growing wealth gap, and many of the follow-on problems that have come with it.

Bitcoin overcomes the "transfer of hard money" problem

Just like gold coins were created by man, Bitcoin too is a technology created by man. Bitcoin, however is a much more profound invention, possibly more of a discovery than an invention in fact. Bitcoin has proven to be unbreakable, incorruptible and has upheld its ability to keep its units scarce, inalienable and counterfeit proof through the nature of its own design.

Since Bitcoin is a digital technology, it can be transferred across international borders almost as quickly as information itself. It therefore severely reduces the need for a derivative to be used to represent money to facilitate digital trade. This means that as the currency we use today continues to fare poorly for many people, bitcoin will continue to stand out as hard money, that just so happens to work as well, functionally, along side it.

Bitcoin will also always be available to anyone who wishes to earn it directly; even China is unable to restrict its citizens from accessing it. The dollar has traditionally become the currency for people who discover that their local currency is unsustainable. Even when the dollar has become illegal to use, it is simply used privately and unofficially. However, because bitcoin does not require you to trade it at a bank in order to use it across borders and across the web, Bitcoin will continue to be a viable escape hatch until we one day hit some critical mass where the world has simply adopted Bitcoin globally and everyone else must adopt it to survive.

Bitcoin has not yet proven that it can support the world at scale. However it can only be tested through real adoption, and just as gold coins were developed to help gold scale, tools will be developed to help overcome problems as they arise; ideally without the need for another derivative, but if necessary, hopefully with one that is more neutral and less corruptible than the derivatives used to represent gold.

Bitcoin blurs the line between commodity and technology

Bitcoin is a technology, it is a tool that requires human involvement to function, however it surprisingly does not allow for any concentration of power. Anyone can help to facilitate Bitcoin's operations, but no one can take control of its behaviour, its reach, or its prioritisation, as it operates autonomously based on a pre-determined, neutral set of rules.

At the same time, its built-in incentive mechanism ensures that people do not have to operate bitcoin out of the good of their heart. Even though the system cannot be co-opted holistically, It will not stop operating while there are people motivated to trade their time and resources to keep it running and earn from others' transaction fees. Although it requires humans to operate it, it remains both neutral and sustainable.

Never before have we developed or discovered a technology that could not be co-opted and used by one person or faction against another. Due to this nature, Bitcoin's units are often described as a commodity; they cannot be usurped or virtually cloned, and they cannot be affected by political biases.

The dangers of derivatives

A derivative is something created, designed or developed to represent another thing in order to solve a particular complication or problem. For example, paper and electronic money was once a derivative of gold.

In the case of Bitcoin, if you cannot link your units of bitcoin to an "address" that you personally hold a cryptographically secure key to, then you very likely have a derivative of bitcoin, not bitcoin itself. If you buy bitcoin on an online exchange and do not withdraw the bitcoin to a wallet that you control, then you legally own an electronic derivative of bitcoin.

Bitcoin is a new technology. It will have a learning curve and it will take time for humanity to learn how to comprehend, authenticate and take control of bitcoin collectively. Having said that, many people all over the world are already using and relying on Bitcoin natively. For many, it will require for people to find the need or a desire for a neutral money like bitcoin, and to have been burned by derivatives of it, before they start to understand the difference between the two. Eventually, it will become an essential part of what we regard as common sense.

Learn for yourself

If you wish to learn more about how to handle bitcoin and avoid derivatives, you can start by searching online for tutorials about "Bitcoin self custody".

There are many options available, some more practical for you, and some more practical for others. Don't spend too much time trying to find the perfect solution; practice and learn. You may make mistakes along the way, so be careful not to experiment with large amounts of your bitcoin as you explore new ideas and technologies along the way. This is similar to learning anything, like riding a bicycle; you are sure to fall a few times, scuff the frame, so don't buy a high performance racing bike while you're still learning to balance.

Introduction

The aim of ELI5 (explain me like I'm 5) is to explain difficult things simply. This is urgently needed in our high-tech world, because only by understanding the technologies can we use them properly and develop them further.

I'm starting my series with Nostr, a relatively new internet protocol. What the hell is an Internet protocol? In formal terms, it is an international standard that has ensured that the Internet has been working pretty well for over 30 years. It is the language in which computers communicate with each other and which you also use every day, probably without realizing it. http(s) transports your request to a server (e.g. Amazon), and html ensures that a nice page is created on your screen from the data supplied. A mail is sent to the mail server with smtp and retrieved from it with imap, and since everyone uses the standard, this works with every app on every operating system and with every mail provider.

And with an e-mail address like roland@pareto.space, you can even move at any time, no matter where. Cool, that's state of the art! But why doesn't this work with chat, for example, is there no protocol? Yes, it's called IRC (Internet Relay Chat → remember the name), but it's hardly ever used. The reasons for this are not technical, but rather apps such as Facebook, Twitter, WhatsApp, Telegram, Instagram, TikTok and others have deliberately created incompatibilities and user dependencies in order to maximize profits.

Since the standard protocol is not used, each app has its own, and we need a handful of apps to exchange information with everyone we know. A mobile phone number is a prerequisite for every account, allowing app manufacturers to track users comprehensively and earn up to USD 30 per account per month by selling the information. The user is no longer the customer, he is the product! Advertising SPAM is the least of the problems with this business model. Servers with millions of user data are a “honey pot”, so they are often hacked and the access data sold. In 2024, the Twitter account of then President Joe Biden was also hacked and no one knew who had written the messages (nor did they before), meaning that the authenticity of the content is not guaranteed with any of these providers. In the same year, the founder of Telegram was taken into custody in France because he refused to build backdoors into his software. Now, to protect “our democracy”, practically anyone can read what information they exchange with whom, e.g. which shampoo certain politicians use.

Why Nostr?

And anyone who actually believes they can practice freedom of expression on social media will quickly find themselves in the situation of Donald Trump (who was president at the time), whose Twitter account was shut down in 2021 (cancel culture). The user data, i.e. their profile, contacts, documents, images, videos and audio files - no longer belong to them anyway but are the property of the platform operator; read the terms and conditions. But no, not a good idea, there are hundreds of pages and they are constantly being changed. So everyone uses apps whose technology they don't understand, whose rules they don't know, where they have no rights and which steal the results of their actions. What would the five-year-old say if his older sister offered to “manage” all his toys and then hand them over if he was good? “You must be crazy”, and with that the toddler proves he has more sense than the majority of adults.

Conclusion: no standards, no data, no rights = no future!

How does Nostr work?

The developers of Nostr realized that the server-client concept had turned into a master-slave concept. The master is synonymous with centralization and becomes the “single point of failure”, which inevitably makes systems dysfunctional. In a distributed peer2peer system, there are no longer any masters but only equal nodes (relays) on which the information is stored. By storing information redundantly on several relays, the system is more resilient in every respect. It is not only nature that has successfully used this principle for millions of years, the Internet was also designed in this way (the ARPAnet was developed by the US military for use in war situations with massive disruptions). All nostr data is stored on relays and the user can choose between public (usually free) and private relays, e.g. for closed groups or for the purpose of data archiving. As documents are stored on several relays, unique document names (URIs = identifiers) are used instead of URLs (locators), making broken links a thing of the past, as are deletions / losses.

Each document (called an event) is signed by the owner, making it authentic and tamper-proof and can only be deleted by the creator. A key pair consisting of a private (nsec) and public key (npub) is used for this, as known from mail encryption (PGP). This represents a Nostr identity that can be supplemented with a picture, name, bio and a readable Nostr address (e.g. roland@pareto.space ), which is all that is needed to use all the resources of the Nostr ecosystem. And this now consists of over a hundred apps with different focuses, e.g. for personal encrypted messages (DM → OxChat), short messages (Damus, Primal), blog posts (Pareto), meetups (Joinstr), groups (Groups), images (Olas), videos (Amethyst), audio chat (Nostr Nests), audio streams (Tunestr), video streams (Zap.Stream), marketplaces (Shopstr) and much more. Registration is done with a single click (single sign-on) and ALL user data is available to the apps (profile, data, contacts, social graph → followers, bookmarks, comments, etc.), in contrast to the fragmented data silos of the present.

Summary: one open standard, all data, all rights = great future!

Why is Nostr the future of the internet?

“Don't build your house on someone else's property” also applies to the Internet - for all app developers, artists, journalists and users, because their data is also valuable. Nostr guarantees ownership of the data and overcomes its fragmentation. Neither use nor creative freedom is restricted by excessive license and usage conditions. Passive users become active participants through interaction, co-creators in a sharing economy (Value4Value). Open source finally restores trust in software and its providers. Open standards enable developers to cooperate more and develop faster, while guaranteeing freedom of choice for users. Which brings us back to our five-year-old for the last time. Children love Lego more than anything, especially the maxi box “Classic”, because it allows them to live out their imagination to the full in terms of combinations. Adults then give them the far too expensive theme packs, with which you can only build one solution according to the instructions. “What's wrong with my parents, when did they take a wrong turn?” the children rightly ask themselves. But the image can be polished up again if they show their children Nostr, because even five-year-olds understand the advantages.

The new Internet is decentralized. The new Internet is self-determined. Nostr is the new Internet.

Ein Lämmchen löschte an einem Bache seinen Durst. Fern von ihm, aber näher der Quelle, tat ein Wolf das gleiche. Kaum erblickte er das Lämmchen, so schrie er:

"Warum trübst du mir das Wasser, das ich trinken will?"

"Wie wäre das möglich", erwiderte schüchtern das Lämmchen, "ich stehe hier unten und du so weit oben; das Wasser fließt ja von dir zu mir; glaube mir, es kam mir nie in den Sinn, dir etwas Böses zu tun!"

"Ei, sieh doch! Du machst es gerade, wie dein Vater vor sechs Monaten; ich erinnere mich noch sehr wohl, daß auch du dabei warst, aber glücklich entkamst, als ich ihm für sein Schmähen das Fell abzog!"

"Ach, Herr!" flehte das zitternde Lämmchen, "ich bin ja erst vier Wochen alt und kannte meinen Vater gar nicht, so lange ist er schon tot; wie soll ich denn für ihn büßen."

"Du Unverschämter!" so endigt der Wolf mit erheuchelter Wut, indem er die Zähne fletschte. "Tot oder nicht tot, weiß ich doch, daß euer ganzes Geschlecht mich hasset, und dafür muß ich mich rächen."

Ohne weitere Umstände zu machen, zerriß er das Lämmchen und verschlang es.

Das Gewissen regt sich selbst bei dem größten Bösewichte; er sucht doch nach Vorwand, um dasselbe damit bei Begehung seiner Schlechtigkeiten zu beschwichtigen.

NIPs

Adds Open Graph “iMeta” tags nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z is proposing that media attachments (images, videos, and other files) may be added to events by including a URL in the event content, along with a matching imeta tag.imeta ("inline metadata") tags add information about media URLs in the event's content. Each imeta tag SHOULD match a URL in the event content. Clients may replace imeta URLs with rich previews. The imeta tag is variadic, and each entry is a space-delimited key/value pair. Each imeta tag MUST have a url, and at least one other field. imeta may include any field specified by NIP 94. There SHOULD be only one imeta tag per URL.

NIP 404 - Ghost Events gu1p introduces Ghost Events—a protocol for creating events that are plausibly deniable with an ephemeral nature, providing a weak binding to the author's identity. It leverages ring signatures, elliptic curve point-hashing, and a distance-based proof-of-work that references Bitcoin block hashes for chronological anchoring.

NIP-88: DLC oracle announcement/attestation event kinds nostr:npub1l6uy9chxyn943cmylrmukd3uqdq8h623nt2gxfh4rruhdv64zpvsx6zvtg is proposing that this is meant to be a scope-reduced version of #919 to allow Discrete Log Contract (DLC) oracle announcements and attestations to be published over Nostr，omitted the DLC offer/accept/encrypted messages that are in #919 and instead focusing only on oracle gossip messages, so that oracles can start using Nostr as an interoperable publishing medium for attestation data. There is upstream work still going on and he don't think they should standardize some of the messages in #919 because the current DLC specs imply the use of ECDSA signatures, without aggregation. The oracle messages though are about as efficient as they can expect them to be, and as oracles form the foundation of a DLC ecosystem they should be prioritized.

Add nip for delegated aggregate signature verification nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn introduces a new verb which can be used to provide a proof via zk-SNARKs to clients that event signatures are valid, without providing the signatures. This allows for some level of deniability, and prevents protected events from being replicated across the network, without requiring users to blindly trust relays.

add restricted to standardized machine-readable prefixes ZigBalthazar is proposing that the restricted prefix is useful in situations where an individual is not whitelisted to write on a relay or has been banned from it. For example, Immortal (websocket/event_handler.go#L125) uses a restricted prefix to send a message when someone who is not whitelisted tries to write on the relay, provided that the whitelist feature is enabled in the configurations.

Zapraisers nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z is proposing that adds a tag to be used in any event as a goal for the amount of zaps to be raised by that event.This has been out on Amethyst for 1.5 years now. The field complements NIP-75 fundraisers used by fundraising sites.

NIP-60: clarify privkey is optional nostr:npub1gujeqakgt7fyp6zjggxhyy7ft623qtcaay5lkc8n8gkry4cvnrzqd3f67z is proposing that redeeming or spending a Cashu with a spending condition requires a corresponding private key to sign the proof. In the context of Nostr, this private key can be the user's own Nostr private key or another private key, not related to the user's Nostr private key. if the client is using the user's own Nostr private key, then the privkey tag wouldn't be needed.

nostr over reticulum initial draft nostr:npub1gmm2ehusvs35zgh6pq84m8hkj4ea0ygy3c9j2e3slzhjjce3kmns5tdaz2 defines how to implement Nostr relay connections over the Reticulum Network Stack, allowing nostr clients and relays to communicate over Reticulum networks instead of traditional WebSocket connections. Nostr over Reticulum (NoR) enables nostr clients and relays to operate over Reticulum's encrypted mesh networking stack while maintaining full compatibility with existing nostr protocols and NIPs.

This Sunday our pastor had to give a sermon with very little preparation. He was leading an elders’ retreat and one of the elders was supposed to preach in his place. The elder who had prepared a sermon ended up in the hospital, so our pastor had to prep fast. He did a great thing. He preached on a passage, but also used that passage to demonstrate how he studies scripture. It was a great sermon. The passage he preached on reminded me of a time in my past when I learned some important lessons.

Almost 20 years ago, I was leading a high school girls Bible study. They picked out a book about Mary and Martha to study. Initially, I wasn’t thrilled with their choice, but didn’t have a theological problem with it, so I agreed for us to study this book. (I don’t remember the name of the book and all my books burnt up when my house burnt down almost 10 years ago). In the end, I probably got more out of the study than any of the girls because I have a definite tendency to be a Martha. What was Martha’s error? Let’s check out the passage:

Now as they went on their way, Jesus entered a village. And a woman named Martha welcomed him into her house. And she had a sister called Mary, who sat at the Lord’s feet and listened to his teaching. But Martha was distracted with much serving. And she went up to him and said, “Lord, do you not care that my sister has left me to serve alone? Tell her then to help me.” But the Lord answered her, “Martha, Martha, you are anxious and troubled about many things, but one thing is necessary. Mary has chosen the good portion, which will not be taken away from her.” (Luke 10:38-42 ESV)

Jesus visited two sisters who welcomed Him into their home. Mary sat at Jesus’s feet and listened to His teaching. Martha spent her time serving everyone and taking care of everyone’s physical needs.

Is taking care of their home and the needs of their guests a bad thing? Of course not, but is it the best?

To make things much worse, Martha then got upset because her sister Mary wasn’t helping her. She was just sitting there taking in every word that Jesus said. Most of us would think Martha’s sacrifices to take care of everyone was better than Mary’s choice to just sit at Jesus’s feet, but did Martha really choose the better path?

Martha then showed that her heart wasn’t focused right and she wasn’t putting the most important things first. She complained to Jesus about her sister’s failure to help and even commanded her Creator, “Tell her then to help me.” Instead of focusing on the words of Jesus, her frustration led her to command her God to act in the way she desired. She was so busy with cooking, cleaning, and serving, that she missed the most important things — spending time with and listening to her God, who was right there in her house with her. This was an opportunity that shouldn’t be missed due to busyness.

How often do we all do this same thing? How often are busy doing good things and miss the most important things? How often are we busy doing ministry that we forget about the reason for the ministry? I don’t know about you, but this happens to me a lot more often than I would like to admit. My biggest sins are usually not what most people think of as sins. My biggest sins are getting so busy that I leave God out of my life. I am so busy serving God that I forget to follow His leading. I am so busy doing what most people would consider good things, but if God is not part of them, they are not worth much. Because I am focusing on getting things done, worry and stress overtake me harming my health and my relationship with Jesus.

I don’t think this is taking Scripture out of context:

We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. (1 John 4:16) {emphasis mine}

Knowing that God is love, read the following passage replacing love with God.

If I speak with the tongues of men and of angels, but do not have love, I have become a noisy gong or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but do not have love, I am nothing. And if I give all my possessions to feed the poor, and if I surrender my body to be burned, but do not have love, it profits me nothing. (1 Corinthians 13:1-3)

If I do not include God in my every action, “it profits me nothing.”

In reality it shouldn’t be allowing God to join me in my works, but me joining God in His works. It should be me listening to God’s word and the leading of the Holy Spirit, looking and seeing what God is doing around me, and me joining in His great works. It should be me allowing God to use me as a tool.

There are times that God speaks clearly and directly to us about what He desires for our lives, but most of the time, He speaks through His word — the Bible. Knowing the Bible helps us to know His will and His eternal plan, so we can follow Him and join Him in His work. Knowing the Bible helps us to differentiate between what is good and what is God’s best. It helps us to prioritize what is really important.

And this I pray, that your love may abound still more and more in real knowledge and all discernment, so that you may approve the things that are excellent, in order to be sincere and blameless until the day of Christ; having been filled with the fruit of righteousness which comes through Jesus Christ, to the glory and praise of God. (Philippians 1:9-11) {emphasis mine}

We can’t obey God, imitate Christ, or follow Him if we refuse to listen and that means spending time in the Bible and time in prayer with Him.

“Listen to Me, you stubborn-minded, Who are far from righteousness.” (Isaiah 46:12)

Come, you children, listen to me; I will teach you the fear of the Lord . (Psalm 34:11)

“Now therefore, O sons, listen to me, For blessed are they who keep my ways. (Proverbs 8:32)

But seek first His kingdom and His righteousness, and all these things will be added to you. (Matthew 6:33)

Our focus on Jesus/God must go beyond knowing Him. It is equally important to obey.

And He [Jesus] said to another, “Follow Me.” But he said, “Lord, permit me first to go and bury my father.” But He said to him, “Allow the dead to bury their own dead; but as for you, go and proclaim everywhere the kingdom of God.” (Luke 9:59-60) [clarification mine]

Once we know what He wants from us, we need to instantly drop what we are doing and follow Him. We can’t put other things ahead of obeying God.

For amazement had seized him and all his companions because of the catch of fish which they had taken; and so also were James and John, sons of Zebedee, who were partners with Simon. And Jesus said to Simon, “Do not fear, from now on you will be catching men.” When they had brought their boats to land, they left everything and followed Him. (Luke 5:9-11) {emphasis mine}

We should be like these apostles, that, after their most successful catch of fish in their entire career as fishermen, “they left everything and followed Him.” We need to let go of what we think is important and obey Him. We need to change our priorities to match God’s priorities.

That may mean we change careers to one that allows more free time for ministry or even going into full time ministry. It may mean letting go on keeping the perfect, clean house, so there is time for ministry, Bible study, or discipling our kids. It may mean changing your habits from watching TV with your family to reading the Bible with your family. For each of us, it will look different, but we need to be like Mary and choose to sit “at the Lord’s feet and listened to his teaching.” We need to be like the apostles who “left everything and followed Him.” We need to choose to put Jesus’s plans before our own. We need to choose to make God’s values our values.

But this is what I commanded them, saying, ‘Obey My voice, and I will be your God, and you will be My people; and you will walk in all the way which I command you, that it may be well with you.’ (Jeremiah 7:23)

Like so many things, it is simple, but it isn’t necessarily easy. We have to change the way we think in order to obey faithfully.

If anyone serves Me, he must follow Me; and where I am, there My servant will be also; if anyone serves Me, the Father will honor him. (John 12:26)

We have to change our priorities to God’s priorities.

Then Jesus said to His disciples, “If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me. (Matthew 16:24)

We need to seek God, His word, and His presence.

As the deer pants for the water brooks,\ So my soul pants for You, O God.\ My soul thirsts for God, for the living God;\ When shall I come and appear before God? (Psalm 42:1-2)

We need to be in God’s word daily, so we know who God is and what He desires from us.

How can a young man keep his way pure?\ By keeping it according to Your word.\ With all my heart I have sought You;\ Do not let me wander from Your commandments.\ *Your word I have treasured in my heart*,\ That I may not sin against You.\ Blessed are You, O Lord;\ Teach me Your statutes.\ With my lips I have told of\ All the ordinances of Your mouth.\ I have rejoiced in the way of Your testimonies,\ As much as in all riches.\ *I will meditate on Your precepts*\ And regard Your ways.\ I shall delight in Your statutes;\ I shall not forget Your word. (Psalm 119:9-16) {emphasis mine}

We need to read the Bible cover to cover so we know the whole word of God. Once we have read through the Bible multiple times, we need to spend time studying the Bible in more depth, so we can know the details, see how the different parts relate to each other, and grow in our knowledge of God. We need to study the Bible and use this knowledge to guide every decision in life — big and small.

Yet they did not listen or incline their ears, but stiffened their necks in order not to listen or take correction. (Jeremiah 17:23)

Just reading the Bible or sitting in church listening to sermons will not make a difference if we don’t truly listen and internalize God’s word, so we can apply it in our every day life. God knows what is best for us and we will never be truly at peace or have true joy until we are living our lives in the light of God’s word and direction.

My prayer for you and for me is that we will have the heart of Mary rather than the heart of Martha and that we will faithfully seek and follow God all of the days of our lives.

Trust Jesus.

A little better today

I'm about to have some coffee, after 14 hours not eating or drinking . I probably won't eat for a couple more hours, either.

I forgot to mention another element of Fast February: the "fiscal fast". Some of you may have heard this term before. It's exactly what it sounds like: stop spending money. In my case it just means not buying anything specifically for myself: no snacks, no takeout, no video games, etc.

- Prepared a Dutch webinar with an short introduction to Nostr - https://welkom.keuzevrijbijmij.nl/evenement/wwebinar-vergroot-je-privacy-op-social-media-10-juli/
- Received a nice t-shirt with the Nostr-PHP logo from Bitpopart who designed the logo
- Did an introduction talk in Dutch on a webinar with 350+ people subscribed on July 10th. 100+ watched the webinar live.
  - Here is the full replay:
    At around 38min the Nostr stuff begins
- Adding pages and wrote some documentation on nostr-php.dev
- Added a custom field field_nsec to the user entity on nostrver.se (Drupal website) using the contrib module field_encrypt. The value of this field is stored encrypted in the database using a self created private key. This key is stored as a blob the server, but multiple ways of storing this are possible. In the Drupal CMS I now can save a Nostr private key for each user which will be fetch from nostr_content_nip23. All changes made in this Drupal contrib module for this: https://git.drupalcode.org/project/nostr_content_nip23/-/commit/cbc172b976aceaff107fea0296a8a476e098467e
- With a nsec stored for each user, it’s possible to select a user when you’re broadcasting an Nostr event from Drupal. The event will be signed with the nsec of the selected user. Quick demo here: https://njump.me/nevent1qvzqqqqqqypzqpnrnguxe8qszsshvgkvhn6qjzxy7xsvx03rlrtddr62haj4lrm3qy88wumn8ghj7mn0wvhxcmmv9uq3camnwvaz7tmwdaehgu3wwdjkyctnw35hstnnda3kjctv9uqzqj75dy5eps3lgwum7f9p2l8sywy7wuxjr08pyhzyzv9mklylaydgdyll3z

This is the third in a series of weekly updates detailing progress on bringing MLS protocol DMs and group messaging to Nostr.

Progress this week

Short update post this week but I made solid progress updating several OpenMLS dependencies and building a new library that implements all the OpenMLS crypto requirements for Nostr.

HPKE-RS

I mentioned a PR last week on the rust-hpke library, that PR is still waiting on review. However, in the meantime, the OpenMLS library depends on a slightly different hpke library, the hpke-rs library.

This library didn't support the secp256k1 curve either so I've opened a PR to add support for secp256k1. That PR uses the RustCrypto library that is the default in the the hpke-rs library. However, because this library is built to allow for swapping out the underlying crypto library (using traits), I was also able to create a new library that uses the secp256k1 library instead of the RustCrypto library. This is the main crypto library that almost all Bitcoin and Nostr apps use so it's important we use that instead of RustCrypto.

OpenMLS Nostr Crypto

The library that I've created (openmls-nostr-crypto) does a few things via separate sub-libraries (crates). The entire library tries to do as little as possible; only implementing the one required ciphersuite for all MLS implementations and the secp256k1 schnorr signatures ciphersuite I've created for Nostr. It's also using the right secp256k1 library to do it.

openmls-nostr-crypto: implementes the crypto traits that the OpenMLS library expects to find for a given provider and removes all the ciphersuites that we don't care about supporting.

hpke-rs-nostr-crypto: This implements the crypto traits that the hpke-rs library expects to find. Again removing all the ciphersuites we don't care about supporting.

I've not yet written any tests for these libraries (which needs to be done) but I've gotten some very simple demos working with OpenMLS using this new set of libraries to handle the crypto.

I've been really impressed with the simplicity of the OpenMLS interface as well. While there is A LOT going on under the hood, the public interface that client developers have to use is clean and simple.

Onward and Upward

Next week I'll continue working on these libraries; adding tests and continuing to build out my small demo app. I've been in touch with the maintainers of the OpenMLS library and I'm hoping to get a review done with them on my PRs and on my new library.

One thing I'll call out here: The review of my library and getting them to review the direction of the project overall will be paid consulting so I'm making sure that I've got as much done as possible before scheduling that time and paying their rates. I'm a strong believer that the right conversation can save you months of wasted time, but I'm also a believer in making sure you're prepared if you're going to drop money on that conversation. 😅

收录的内容中 kind=1的部分，实话说质量不高。所以我增加了kind=30023 长文的article，但是更新的太少，多个relays 的服务器也没有多少长文。

所有搜索nostr如果需要产生价值，需要有高质量的文章和新闻。而且现在有很多机器人的文章充满着浪费空间的作用，其他作用都用不上。

https://www.duozhutuan.com 目前放的是给搜索引擎提供搜索的原材料。没有做UI给人类浏览。所以看上去是粗糙的。我并没有打算去做一个发microblog的 web客户端，那类的客户端太多了。

我觉得nostr社区需要解决的还是应用。如果仅仅是microblog 感觉有点够呛

幸运的是npub.pro 建站这样的，我觉得有点意思。

yakihonne 智能widget 也有意思

我做的TaskQ5 我自己在用了。分布式的任务系统，也挺好的。

KRIS menjamin semua golongan masyarakat mendapatkan perlakuan sama dari rumah sakit, baik pelayanan medis maupun nonmedis.

Demi memberikan peningkatan kualitas layanan kesehatan kepada masyarakat, pemerintah baru saja mengeluarkan Peraturan Presiden (Perpres) nomor 59 tahun 2024 tentang Jaminan Kesehatan. Melalui perpres itu, Presiden Joko Widodo (Jokowi) telah menghapus perbedaan kelas layanan 1, 2, dan 3 dalam Badan Penyelenggara Jaminan Sosial atau BPJS Kesehatan.

Layanan berbasis kelas itu diganti dengan KRIS (Kelas Rawat Inap Standar). Berkaitan dengan lahirnya Perpres 59/2024 tentang Perubahan Ketiga atas Perpres 82/2018 tentang Jaminan Kesehatan, Presiden Joko Widodo telah memerintahkan seluruh rumah sakit yang bekerja sama dengan BPJS Kesehatan melaksanakannya.

Kebijakan baru itu mulai berlaku per 8 Mei 2024 dan paling lambat 30 Juni 2025. Dalam jangka waktu tersebut, rumah sakit dapat menyelenggarakan sebagian atau seluruh pelayanan rawat inap berdasarkan KRIS sesuai dengan kemampuan rumah sakit.

Lantas apa yang menjadi pembeda dari sisi layanan dengan layanan rawat inap sesuai Perpres 59/2024? Dahulu sistem layanan rawat BPJS Kesehatan dibagi berdasarkan kelas yang dibagi masing-masing kelas 1, 2, dan 3. Namun, melalui perpres, layanan kepada masyarakat tidak dibedakan lagi.

Pelayanan rawat inap yang diatur dalam perpres itu--dikenal dengan nama KRIS—menjadi sistem baru yang digunakan dalam pelayanan rawat inap BPJS Kesehatan di rumah sakit-rumah sakit. Dengan KRIS, semua golongan masyarakat akan mendapatkan perlakuan yang sama dari rumah sakit, baik dalam hal pelayanan medis maupun nonmedis.

Dengan lahirnya Perpres 59/2024, tarif iuran BPJS Kesehatan pun juga akan berubah. Hanya saja, dalam Perpres itu belum dicantumkan secara rinci ihwal besar iuran yang baru. Besaran iuran baru BPJS Kesehatan itu sesuai rencana baru ditetapkan pada 1 Juli 2025.

“Penetapan manfaat, tarif, dan iuran sebagaimana dimaksud ditetapkan paling lambat tanggal 1 Juli 2025,” tulis aturan tersebut, dikutip Senin (13/5/2024).

Itu artinya, iuran BPJS Kesehatan saat ini masih sama seperti sebelumnya, yakni sesuai dengan kelas yang dipilih. Namun perpres itu tetap berlaku sembari menanti lahirnya peraturan lanjutan dari perpres tersebut.

Kesiapan Rumah Sakit

Berkaitan dengan lahirnya kebijakan layanan kesehatan tanpa dibedakan kelas lagi, Kementerian Kesehatan (Kemenkes) menegaskan mayoritas rumah sakit di Indonesia siap untuk menjalankan layanan KRIS untuk pasien BPJS Kesehatan.

Kesiapan itu diungkapkan oleh Dirjen Pelayanan Kesehatan Kemenkes Azhar Jaya. “Survei kesiapan RS terkait KRIS sudah dilakukan pada 2.988 rumah sakit dan yang sudah siap menjawab isian 12 kriteria ada sebanyak 2.233 rumah sakit,” ujar Azhar.

Sebagai informasi, KRIS adalah pengganti layanan Kelas 1, 2, dan 3 BPJS Kesehatan yang bertujuan untuk memberikan layanan kesehatan secara merata tanpa melihat besaran iurannya.

Melalui KRIS, rumah sakit perlu menyiapkan sarana dan prasarana sesuai dengan 12 kriteria kelas rawat inap standar secara bertahap. Apa saja ke-12 kriteria KRIS itu?

Sesuai bunyi Pasal 46A Perpres 59/2024, disyaratkan kriteria fasilitas perawatan dan pelayanan rawat inap KRIS meliputi komponen bangunan yang digunakan tidak boleh memiliki tingkat porositas yang tinggi serta terdapat ventilasi udara dan kelengkapan tidur.

Demikian pula soal pencahayaan ruangan. Perpres itu juga mengatur pencahayaan ruangan buatan mengikuti kriteria standar 250 lux untuk penerangan dan 50 lux untuk pencahayaan tidur, temperature ruangan 20--26 derajat celcius.

Tidak hanya itu, layanan rawat inap berdasarkan perpres itu mensyaratkan fasilitas layanan yang membagi ruang rawat berdasarkan jenis kelamin pasien, anak atau dewasa, serta penyakit infeksi atau noninfeksi.

Selain itu, kriteria lainnya adalah keharusan bagi penyedia layanan untuk mempertimbangkan kepadatan ruang rawat dan kualitas tempat tidur, penyediaan tirai atau partisi antartempat tidur, kamar mandi dalam ruangan rawat inap yang memenuhi standar aksesibilitas, dan menyediakan outlet oksigen.

Selain itu, kelengkapan tempat tidur berupa adanya dua kotak kontak dan nurse call pada setiap tempat tidur dan adanya nakas per tempat tidur. Kepadatan ruang rawat inap maksimal empat tempat tidur dengan jarak antara tepi tempat tidur minimal 1,5 meter.

Tirai/partisi dengan rel dibenamkan menempel di plafon atau menggantung. Kamar mandi dalam ruang rawat inap serta kamar mandi sesuai dengan standar aksesibilitas dan outlet oksigen.

Azhar menjamin, Kemenkes akan menjalankan hal tersebut sesuai dengan tupoksi yang ada. “Tentu saja kami akan bekerja sama dengan BPJS Kesehatan dalam implementasi dan pengawasannya di lapangan,” ujar Azhar.

Berkaitan dengan perpres jaminan kesehatan itu, Direktur Utama BPJS Kesehatan Ghufron Mukti menilai, perpres tersebut berorientasi pada penyeragaman kelas rawat inap yang mengacu pada 12 kriteria. "Bahwa perawatan ada kelas rawat inap standar dengan 12 kriteria, untuk peserta BPJS, maka sebagaimana sumpah dokter tidak boleh dibedakan pemberian pelayan medis atas dasar suku, agama, status sosial atau beda iurannya," ujarnya.

Jika ada peserta ingin dirawat pada kelas yang lebih tinggi, kata Ghufron, maka diperbolehkan selama hal itu dipengaruhi situasi nonmedis. Hal itu disebutkan dalam Pasal 51 Perpres Jaminan Kesehatan diatur ketentuan naik kelas perawatan.

Menurut pasal tersebut, naik kelas perawatan dilakukan dengan cara mengikuti asuransi kesehatan tambahan atau membayar selisih antara biaya yang dijamin oleh BPJS Kesehatan dengan biaya yang harus dibayar akibat peningkatan pelayanan.

Selisih antara biaya yang dijamin oleh BPJS Kesehatan dengan biaya pelayanan dapat dibayar oleh peserta bersangkutan, pemberi kerja, atau asuransi kesehatan tambahan.

Ghufron Mukti juga mengimbau pengelola rumah sakit tidak mengurangi jumlah tempat tidur perawatan pasien dalam upaya memenuhi kriteria KRIS. "Pesan saya jangan dikurangi akses dengan mengurangi jumlah tempat tidur. Pertahankan jumlah tempat tidur dan penuhi persyaratannya dengan 12 kriteria tersebut," tegas Ghufron.
