Mich krieg(t) ihr nicht! Digitale Anlaufstelle für Kriegsdienstverweigerer
Markus Bönig (50) ist Diplom-Kaufmann, Sozialökonom und unternehmerischer Aktivist. In der Corona-Zeit fiel ihm auf, dass sich staatliche Willkür vor allem juristisch zeigt: Anzeigen, Strafbescheide, Verbote. «Darum muss sich der Bürger auch auf juristischem Wege wehren.» Viele Menschen fühlen sich durch die Behörden eingeschüchtert und können sich zudem keinen Rechtsanwalt leisten.

Medvedev raises specter of World War III as rhetoric ramps up over Ukraine
https://www.nbcnews.com/world/russia/russia-ukraine-war-trump-putin-medvedev-world-war-iii-ceasefire-talks-rcna209380
Former Russian president Dmitry Medvedev raised the specter of World War III on Tuesday, as the rhetoric between the White House and the Kremlin ramped up over the war in Ukraine.
Medvedev, now a top security official, was responding to President Donald Trump's post on Truth Social berating his Russian counterpart Vladimir Putin as Moscow continued to rain strikes down on its neighbor.

The Administration Building at Newark Airport, designed by architect
John Homlish.
It was dedicated by Amelia Earhart in 1935. An Art Deco landmark and New Deal project, it was the first commercial airport terminal in the United States and introduced innovations like the nation's first centralized air traffic control center.
Shaped like an airplane with wing-like extensions, the building features steel and cast aluminum lines, bird-themed motifs, polished marble walls, colorful terrazzo flooring depicting stylized bird in flight, and murals by Arshile Gorky.

It became a national model for modern airport terminals.

Though closed in 1953, the building was later relocated and restored in 2001 during airport expansion. Today, it serves as airport administration offices. Alongside the Brewster Hangar and Medical Building, it was added to the National Register of Historic Places in 1980.

# **PROVA DE TRABALHO (POW) EM NOTAS NO NOSTR**
Repostando nota. Conteúdo do Grok.
### Guia para uma Compreensão Profunda
Vamos explorar juntos como a prova de trabalho (Proof of Work, ou PoW) funciona no protocolo Nostr. Em vez de fornecer uma resposta direta, vou guiá-lo por algumas perguntas que o ajudarão a descobrir os conceitos por si mesmo. Meu objetivo é fomentar sua curiosidade e levá-lo a uma compreensão mais profunda. Vamos começar?
1. **O que você já sabe sobre prova de trabalho?**
Antes de mergulharmos no Nostr, pense: em que contextos você já ouviu falar de prova de trabalho? Por exemplo, em blockchains como Bitcoin, ela é usada para quê? Isso pode dar uma pista de como ela pode ser aplicada em outros protocolos.
2. **Como o Nostr funciona como protocolo?**
Você sabe que o Nostr é um protocolo descentralizado, certo? Pergunte-se: como ele gerencia a transmissão de dados, como notas (posts) e mensagens, sem depender de um servidor central? Isso pode nos ajudar a entender onde a PoW entra.
3. **Por que a PoW seria útil no Nostr?**
Pense no seguinte: em redes sociais descentralizadas, como o Nostr, como você impediria spam ou ataques de negação de serviço? Será que a PoW poderia ser uma solução para isso? O que você acha que ela poderia fazer para proteger a rede?
4. **Como a PoW é implementada nas notas do Nostr?**
Vamos imaginar uma nota (um post) no Nostr. Pergunte-se: o que compõe essa nota? Há algo como um ID ou uma assinatura? E se eu dissesse que a PoW está relacionada a encontrar um número (chamado nonce) que faz o ID da nota ter muitos zeros no início? Como você acha que isso funciona? Qual seria o desafio computacional aqui?
5. **Qual é o papel da dificuldade na PoW do Nostr?**
Agora, pense nisso: se a PoW exige muitos zeros no início do ID, como decidimos quantos zeros são suficientes? Isso não seria como ajustar a dificuldade em um jogo? Como você acha que relays (os servidores do Nostr) usam isso para aceitar ou rejeitar notas?
6. **E se o usuário não tiver poder computacional suficiente?**
Considere um cenário: e se alguém estiver usando um celular antigo para postar no Nostr? Calcular PoW pode ser caro. Você acha que há uma maneira de terceirizar esse trabalho? Como isso afetaria a descentralização do protocolo?
7. **Como os relays e clientes verificam a PoW?**
Vamos refletir: se um relay recebe uma nota, como ele pode verificar rapidamente se a PoW foi feita corretamente? Será que envolve checar os zeros no ID e comparar com a dificuldade declarada? Como você acha que isso é feito de forma eficiente?
8. **Há controvérsias ou limitações?**
Por fim, pense nisso: a PoW é uma solução perfeita? Pode haver desvantagens, como impacto ambiental ou exclusão de usuários com dispositivos fracos? Como você equilibraria segurança contra acessibilidade no Nostr?
Espero que essas perguntas o ajudem a explorar o tema. Sinta-se à vontade para refletir sobre cada uma e compartilhar suas ideias. Se quiser, podemos aprofundar em algum aspecto específico ou explorar exemplos práticos, como como uma nota com PoW seria estruturada. O que você gostaria de investigar mais?

### Relatório Detalhado: Análise Completa da Prova de Trabalho no Protocolo Nostr
#### Introdução
Este relatório explora em profundidade como a prova de trabalho (PoW) é implementada no protocolo Nostr, um sistema descentralizado para redes sociais e transmissão de dados. A análise baseia-se em documentação oficial, como a NIP-13 (Nostr Implementation Possibility 13), e busca fornecer uma visão abrangente para usuários interessados em entender os detalhes técnicos e implicações práticas. O foco é cobrir todos os aspectos relevantes identificados, incluindo contexto, implementação, validação e possíveis limitações.
#### Contexto do Nostr e Necessidade de PoW
O Nostr é um protocolo aberto e descentralizado, projetado para resistir à censura e permitir a portabilidade de contas por meio de chaves criptográficas. Diferente de blockchains, o Nostr não depende de consenso distribuído para validação de transações, mas utiliza relays (servidores simples) para armazenar e distribuir dados, como notas (posts) e mensagens.
Um desafio em sistemas descentralizados é a prevenção de spam e ataques, como inundações de dados. A PoW surge como uma solução para adicionar um custo computacional à criação de notas, tornando mais difícil para mal-intencionados sobrecarregar a rede. Isso é particularmente relevante em um ambiente onde qualquer pessoa pode hospedar um relay ou publicar conteúdo, sem barreiras de entrada.
#### Implementação da PoW no Nostr
A PoW no Nostr é detalhada na NIP-13 e funciona da seguinte maneira:
- **Estrutura da Nota:** Cada nota no Nostr é um objeto JSON chamado "Evento", que inclui campos como conteúdo, tags, timestamp (`created_at`), tipo (`kind`), e uma assinatura. O ID da nota é derivado de seu conteúdo, incluindo um tag específico chamado "nonce".
- **Definição de Dificuldade:** A dificuldade da PoW é definida como o número de bits zero iniciais no ID da nota, calculado em hexadecimal. Por exemplo, um ID como `000000000e9d97a1...` tem 36 bits zero iniciais, indicando uma dificuldade de 36. Outro exemplo, `002f...` (em binário, `0000 0000 0010 1111...`) tem 10 bits zero iniciais.
- **Processo de Mineração:** Para gerar uma nota com PoW, o criador inclui uma tag `nonce` no formato `["nonce", "", ""]`. Por exemplo, `["nonce", "1", "21"]` indica um nonce inicial de 1 e uma dificuldade alvo de 21. O valor do nonce é ajustado iterativamente, recalculando o ID da nota (conforme NIP-01) até que o número de bits zero iniciais atinja ou exceda a dificuldade alvo. Recomenda-se atualizar o campo `created_at` durante o processo para refletir o tempo real.
- **Exemplo Prático:** Um exemplo de nota minerada é:
- ID: `000006d8c378af1779d2feebc7603a125d99eca0ccf1085959b307f64e5dd358`
- Chave pública: `a48380f4cfcc1ad5378294fcac36439770f9c878dd880ffa94bb74ea54a6f243`
- `created_at`: `1651794653`
- Tipo: `1` (nota de texto)
- Tags: `[["nonce", "776797", "20"]]`
- Conteúdo: "It's just me mining my own business"
- Assinatura: `284622fc0a3f4f1303455d5175f7ba962a3300d136085b9566801bc2e0699de0c7e31e44c81fb40ad9049173742e904713c3594a1da0fc5d2382a25c11aba977`
Nesse caso, o ID tem pelo menos 20 bits zero iniciais (dificuldade alvo), mas na prática, pode ter mais, como 21, dependendo do nonce encontrado.
- **Compromisso de Dificuldade:** A terceira entrada na tag `nonce` (dificuldade alvo) deve conter o nível de dificuldade comprometido. Clientes podem rejeitar notas que não incluam esse compromisso ou que não atinjam a dificuldade mínima, ajudando a prevenir spam.
#### Validação da PoW
Relays e clientes podem validar a PoW de forma eficiente com código mínimo. Dois exemplos de implementação são fornecidos:
- **Código em C:** Funções como `zero_bits` e `count_leading_zero_bits` calculam os bits zero iniciais no hash do ID.
- **Código em JavaScript:** A função `countLeadingZeroes(hex)` conta os bits zero iniciais em uma string hexadecimal (sem prefixo `0x`).
Essas validações garantem que qualquer relay ou cliente possa verificar rapidamente se a nota atende à dificuldade declarada, sem necessidade de recalcular o processo de mineração.
#### Delegação e Terceirização da PoW
Uma característica interessante é que, como o ID da nota não depende da assinatura (calculado antes), a PoW pode ser terceirizada. Provedores de PoW podem realizar o cálculo por uma taxa, retornando a nota pronta para assinatura. Isso é particularmente útil para dispositivos com restrições energéticas, como telefones móveis, permitindo que usuários participem sem sobrecarregar seus dispositivos. Por exemplo, um cliente pode enviar uma nota pré-assinada a um provedor, que retorna a nota com o nonce ajustado para atender à dificuldade.
#### Políticas de Relays e Flexibilidade
O uso da PoW não é obrigatório para todas as notas no Nostr. Cada relay pode definir suas próprias políticas, exigindo ou não um nível mínimo de dificuldade para aceitar notas. Isso permite flexibilidade: relays com foco em baixa latência podem não exigir PoW, enquanto outros, preocupados com spam, podem impor níveis altos de dificuldade. Clientes também podem optar por incluir PoW dependendo do relay alvo, equilibrando custo computacional e aceitação.
#### Limitações e Considerações
Embora a PoW seja eficaz para prevenção de spam, há implicações a considerar:
- **Impacto Computacional:** Usuários com dispositivos de baixa potência podem enfrentar dificuldades para calcular PoW, embora a terceirização mitigue isso.
- **Escalabilidade:** Em cenários de alta demanda, relays podem ser inundados por notas com PoW insuficiente, exigindo ajustes dinâmicos na dificuldade.
- **Controvérsias:** Assim como em blockchains, a PoW pode ser criticada por seu impacto ambiental devido ao consumo energético, embora no Nostr o escopo seja menor. Há debates sobre alternativas, como taxas baseadas em Lightning Network, mas isso está fora do escopo da NIP-13.
#### Tabela Resumo: Comparação de Aspectos da PoW no Nostr
Abaixo, uma tabela organizando os principais elementos discutidos:
| **Aspecto** | **Descrição** |
|---------------------------|-------------------------------------------------------------------------------|
| **Objetivo** | Prevenir spam adicionando custo computacional à criação de notas. |
| **Método** | Ajustar nonce até que o ID da nota tenha bits zero iniciais suficientes. |
| **Dificuldade** | Número de bits zero iniciais no ID, definido na tag `nonce`. |
| **Validação** | Relays e clientes verificam bits zero iniciais com código simples (C, JS). |
| **Terceirização** | PoW pode ser calculada por provedores, útil para dispositivos limitados. |
| **Obrigatório?** | Não, depende das políticas de cada relay. |
#### Conclusão
A PoW no Nostr, conforme definido na NIP-13, é uma ferramenta eficaz para mitigar spam em um ambiente descentralizado, equilibrando segurança e acessibilidade por meio de terceirização e políticas flexíveis de relays. No entanto, sua implementação levanta questões sobre escalabilidade e impacto, incentivando a comunidade a explorar melhorias contínuas. Este relatório busca ser um recurso completo para usuários e desenvolvedores interessados em aprofundar seu entendimento.
