Nostr is not decentralized nor censorship-resistant

Peter Todd has been saying this for a long time and all the time I've been thinking he is misunderstanding everything, but I guess a more charitable interpretation is that he is right.

Nostr today is indeed centralized.

Yesterday I published two harmless notes with the exact same content at the same time. In two minutes the notes had a noticeable difference in responses:

The top one was published to wss://nostr.wine, wss://nos.lol, wss://pyramid.fiatjaf.com. The second was published to the relay where I generally publish all my notes to, wss://pyramid.fiatjaf.com, and that is announced on my NIP-05 file and on my NIP-65 relay list.

A few minutes later I published that screenshot again in two identical notes to the same sets of relays, asking if people understood the implications. The difference in quantity of responses can still be seen today:

These results are skewed now by the fact that the two notes got rebroadcasted to multiple relays after some time, but the fundamental point remains.

What happened was that a huge lot more of people saw the first note compared to the second, and if Nostr was really censorship-resistant that shouldn't have happened at all.

Some people implied in the comments, with an air of obviousness, that publishing the note to "more relays" should have predictably resulted in more replies, which, again, shouldn't be the case if Nostr is really censorship-resistant.

What happens is that most people who engaged with the note are following me, in the sense that they have instructed their clients to fetch my notes on their behalf and present them in the UI, and clients are failing to do that despite me making it clear in multiple ways that my notes are to be found on wss://pyramid.fiatjaf.com.

If we were talking not about me, but about some public figure that was being censored by the State and got banned (or shadowbanned) by the 3 biggest public relays, the sad reality would be that the person would immediately get his reach reduced to ~10% of what they had before. This is not at all unlike what happened to dozens of personalities that were banned from the corporate social media platforms and then moved to other platforms -- how many of their original followers switched to these other platforms? Probably some small percentage close to 10%. In that sense Nostr today is similar to what we had before.

Peter Todd is right that if the way Nostr works is that you just subscribe to a small set of relays and expect to get everything from them then it tends to get very centralized very fast, and this is the reality today.

Peter Todd is wrong that Nostr is inherently centralized or that it needs a protocol change to become what it has always purported to be. He is in fact wrong today, because what is written above is not valid for all clients of today, and if we drive in the right direction we can successfully make Peter Todd be more and more wrong as time passes, instead of the contrary.

Sem dúvida, a escalada autoritária do totalitarismo cultural progressista nos últimos anos tem sido sumariamente deletéria e prejudicial para a liberdade de expressão. Como seria de se esperar, a cada dia que passa o autoritarismo progressista continua a se expandir de maneira irrefreável, prejudicando a liberdade dos indivíduos de formas cada vez mais deploráveis e contundentes.

Com a ascensão da tirania politicamente correta e sua invasão a todos os terrenos culturais, o autoritarismo progressista foi se alastrando e consolidando sua hegemonia em determinados segmentos. Com a eventual eclosão e a expansão da opressiva e despótica cultura do cancelamento — uma progênie inevitável do totalitarismo progressista —, todas as pessoas que manifestam opiniões, crenças ou posicionamentos que não estão alinhados com as pautas universitárias da moda tornam-se um alvo.

Há algumas semanas, vimos a enorme repercussão causada pelo caso envolvendo o jogador profissional de vôlei Maurício Sousa, que foi cancelado pelo simples fato de ter emitido sua opinião pessoal sobre um personagem de história em quadrinhos, Jon Kent, o novo Superman, que é bissexual. Maurício Sousa reprovou a conduta sexual do personagem, o que é um direito pessoal inalienável que ele tem. Ele não é obrigado a gostar ou aprovar a bissexualidade. Como qualquer pessoa, ele tem o direito pleno de criticar tudo aquilo que ele não gosta. No entanto, pelo simples fato de emitir a sua opinião pessoal, Maurício Sousa foi acusado de homofobia e teve seu contrato rescindido, sendo desligado do Minas Tênis Clube.

Lamentavelmente, Maurício Sousa não foi o primeiro e nem será o último indivíduo a sofrer com a opressiva e autoritária cultura do cancelamento. Como uma tirania cultural que está em plena ascensão e usufrui de um amplo apoio do establishment, essa nova forma de totalitarismo cultural colorido e festivo está se impondo de formas e maneiras bastante contundentes em praticamente todas as esferas da sociedade contemporânea. Sua intenção é relegar ao ostracismo todos aqueles que não se curvam ao totalitarismo progressista, criminalizando opiniões e crenças que divergem do culto à libertinagem hedonista pós-moderna. Oculto por trás de todo esse ativismo autoritário, o que temos de fato é uma profunda hostilidade por padrões morais tradicionalistas, cristãos e conservadores.

No entanto, é fundamental entendermos uma questão imperativa, que explica em partes o conflito aqui criado — todos os progressistas contemporâneos são crias oriundas do direito positivo. Por essa razão, eles jamais entenderão de forma pragmática e objetiva conceitos como criminalidade, direitos de propriedade, agressão e liberdade de expressão pela perspectiva do jusnaturalismo, que é manifestamente o direito em seu estado mais puro, correto, ético e equilibrado.

Pela ótica jusnaturalista, uma opinião é uma opinião. Ponto final. E absolutamente ninguém deve ser preso, cancelado, sabotado ou boicotado por expressar uma opinião particular sobre qualquer assunto. Palavras não agridem ninguém, portanto jamais poderiam ser consideradas um crime em si. Apenas deveriam ser tipificados como crimes agressões de caráter objetivo, como roubo, sequestro, fraude, extorsão, estupro e infrações similares, que representam uma ameaça direta à integridade física da vítima, ou que busquem subtrair alguma posse empregando a violência.

Infelizmente, a geração floquinho de neve — terrivelmente histérica, egocêntrica e sensível — fica profundamente ofendida e consternada sempre que alguém defende posicionamentos contrários à religião progressista. Por essa razão, os guerreiros da justiça social sinceramente acreditam que o papai-estado deve censurar todas as opiniões que eles não gostam de ouvir, assim como deve também criar leis para encarcerar todos aqueles que falam ou escrevem coisas que desagradam a militância.

Como a geração floquinho de neve foi criada para acreditar que todas as suas vontades pessoais e disposições ideológicas devem ser sumariamente atendidas pelo papai-estado, eles embarcaram em uma cruzada moral que pretende erradicar todas as coisas que são ofensivas à ideologia progressista; só assim eles poderão deflagrar na Terra o seu tão sonhado paraíso hedonista e igualitário, de inimaginável esplendor e felicidade.

Em virtude do seu comportamento intrinsecamente despótico, autoritário e egocêntrico, acaba sendo inevitável que militantes progressistas problematizem tudo aquilo que os desagrada.

Como são criaturas inúteis destituídas de ocupação real e verdadeiro sentido na vida, sendo oprimidas unicamente na sua própria imaginação, militantes progressistas precisam constantemente inventar novos vilões para serem combatidos.

Partindo dessa perspectiva, é natural para a militância que absolutamente tudo que exista no mundo e que não se enquadra com as regras autoritárias e restritivas da religião progressista seja encarado como um problema. Para a geração floquinho de neve, o capitalismo é um problema. O fascismo é um problema. A iniciativa privada é um problema. O homem branco, tradicionalista, conservador e heterossexual é um problema. A desigualdade é um problema. A liberdade é um problema. Monteiro Lobato é um problema (sim, até mesmo o renomado ícone da literatura brasileira, autor — entre outros títulos — de Urupês, foi vítima da cultura do cancelamento, acusado de ser racista e eugenista).

Para a esquerda, praticamente tudo é um problema. Na mentalidade da militância progressista, tudo é motivo para reclamação. Foi em função desse comportamento histérico, histriônico e infantil que o famoso pensador conservador-libertário americano P. J. O’Rourke afirmou que “o esquerdismo é uma filosofia de pirralhos chorões”. O que é uma verdade absoluta e irrefutável em todos os sentidos.

De fato, todas as filosofias de esquerda de forma geral são idealizações utópicas e infantis de um mundo perfeito. Enquanto o mundo não se transformar naquela colorida e vibrante utopia que é apresentada pela cartilha socialista padrão, militantes continuarão a reclamar contra tudo o que existe no mundo de forma agressiva, visceral e beligerante. Evidentemente, eles não vão fazer absolutamente nada de positivo ou construtivo para que o mundo se transforme no gracioso paraíso que eles tanto desejam ver consolidado, mas eles continuarão a berrar e vociferar muito em sua busca incessante pela utopia, marcando presença em passeatas inúteis ou combatendo o fascismo imaginário nas redes sociais.

Sem dúvida, estamos muito perto de ver leis absurdas e estúpidas sendo implementadas, para agradar a militância da terra colorida do assistencialismo eterno onde nada é escasso e tudo cai do céu. Em breve, você não poderá usar calças pretas, pois elas serão consideradas peças de vestuário excessivamente heterossexuais. Apenas calças amarelas ou coloridas serão permitidas. Você também terá que tingir de cor-de-rosa uma mecha do seu cabelo; pois preservar o seu cabelo na sua cor natural é heteronormativo demais da sua parte, sendo portanto um componente demasiadamente opressor da sociedade.

Você também não poderá ver filmes de guerra ou de ação, apenas comédias românticas, pois certos gêneros de filmes exaltam a violência do patriarcado e isso impede o mundo de se tornar uma graciosa festa colorida de fraternidades universitárias ungidas por pôneis resplandecentes, hedonismo infinito, vadiagem universitária e autogratificação psicodélica, que certamente são elementos indispensáveis para se produzir o paraíso na Terra.

Sabemos perfeitamente, no entanto, que dentre as atitudes “opressivas” que a militância progressista mais se empenha em combater, estão o racismo, o fascismo, o machismo e a homofobia. No entanto, é fundamental entender que ser racista, fascista, machista ou homofóbico não são crimes em si. Na prática, todos esses elementos são apenas traços de personalidade; e eles não podem ser pura e simplesmente criminalizados porque ideólogos e militantes progressistas iluminados não gostam deles.

Tanto pela ética quanto pela ótica jusnaturalista, é facilmente compreensível entender que esses traços de personalidade não podem ser criminalizados ou proibidos simplesmente porque integrantes de uma ideologia não tem nenhuma apreciação ou simpatia por eles. Da mesma forma, nenhum desses traços de personalidade representa em si um perigo para a sociedade, pelo simples fato de existir. Por incrível que pareça, até mesmo o machismo, o racismo, o fascismo e a homofobia merecem a devida apologia.

Mas vamos analisar cada um desses tópicos separadamente para entender isso melhor.

Racismo

Quando falamos no Japão, normalmente não fazemos nenhuma associação da sociedade japonesa com o racismo. No entanto, é incontestável o fato de que a sociedade japonesa pode ser considerada uma das sociedades mais racistas do mundo. E a verdade é que não há absolutamente nada de errado com isso.

Aproximadamente 97% da população do Japão é nativa; apenas 3% do componente populacional é constituído por estrangeiros (a população do Japão é estimada em aproximadamente 126 milhões de habitantes). Isso faz a sociedade japonesa ser uma das mais homogêneas do mundo. As autoridades japonesas reconhecidamente dificultam processos de seleção e aplicação a estrangeiros que desejam se tornar residentes. E a maioria dos japoneses aprova essa decisão.

Diversos estabelecimentos comerciais como hotéis, bares e restaurantes por todo o país tem placas na entrada que dizem “somente para japoneses” e a maioria destes estabelecimentos se recusa ostensivamente a atender ou aceitar clientes estrangeiros, não importa quão ricos ou abastados sejam.

Na Terra do Sol Nascente, a hostilidade e a desconfiança natural para com estrangeiros é tão grande que até mesmo indivíduos que nascem em algum outro país, mas são filhos de pais japoneses, não são considerados cidadãos plenamente japoneses.

Se estes indivíduos decidem sair do seu país de origem para se estabelecer no Japão — mesmo tendo descendência nipônica legítima e inquestionável —, eles enfrentarão uma discriminação social considerável, especialmente se não dominarem o idioma japonês de forma impecável. Esse fato mostra que a discriminação é uma parte tão indissociável quanto elementar da sociedade japonesa, e ela está tão profundamente arraigada à cultura nipônica que é praticamente impossível alterá-la ou atenuá-la por qualquer motivo.

A verdade é que — quando falamos de um país como o Japão — nem todos os discursos politicamente corretos do mundo, nem a histeria progressista ocidental mais inflamada poderão algum dia modificar, extirpar ou sequer atenuar o componente racista da cultura nipônica. E isso é consequência de uma questão tão simples quanto primordial: discriminar faz parte da natureza humana, sendo tanto um direito individual quanto um elemento cultural inerente à muitas nações do mundo. Os japoneses não tem problema algum em admitir ou institucionalizar o seu preconceito, justamente pelo fato de que a ideologia politicamente correta não tem no oriente a força e a presença que tem no ocidente.

E é fundamental enfatizar que, sendo de natureza pacífica — ou seja, não violando nem agredindo terceiros —, a discriminação é um recurso natural dos seres humanos, que está diretamente associada a questões como familiaridade e segurança.

Absolutamente ninguém deve ser forçado a apreciar ou integrar-se a raças, etnias, pessoas ou tribos que não lhe transmitem sentimentos de segurança ou familiaridade. Integração forçada é o verdadeiro crime, e isso diversos países europeus — principalmente os escandinavos (países que lideram o ranking de submissão à ideologia politicamente correta) — aprenderam da pior forma possível.

A integração forçada com imigrantes islâmicos resultou em ondas de assassinato, estupro e violência inimagináveis para diversos países europeus, até então civilizados, que a imprensa ocidental politicamente correta e a militância progressista estão permanentemente tentando esconder, porque não desejam que o ocidente descubra como a agenda “humanitária” de integração forçada dos povos muçulmanos em países do Velho Mundo resultou em algumas das piores chacinas e tragédias na história recente da Europa.

Ou seja, ao discriminarem estrangeiros, os japoneses estão apenas se protegendo e lutando para preservar sua nação como um ambiente cultural, étnico e social que lhe é seguro e familiar, assim se opondo a mudanças bruscas, indesejadas e antinaturais, que poderiam comprometer a estabilidade social do país.

A discriminação — sendo de natureza pacífica —, é benévola, salutar e indubitavelmente ajuda a manter a estabilidade social da comunidade. Toda e qualquer forma de integração forçada deve ser repudiada com veemência, pois, mais cedo ou mais tarde, ela irá subverter a ordem social vigente, e sempre será acompanhada de deploráveis e dramáticos resultados.

Para citar novamente os países escandinavos, a Suécia é um excelente exemplo do que não fazer. Tendo seguido o caminho contrário ao da discriminação racional praticada pela sociedade japonesa, atualmente a sociedade sueca — além de afundar de forma consistente na lama da libertinagem, da decadência e da deterioração progressista — sofre em demasia com os imigrantes muçulmanos, que foram deixados praticamente livres para matar, saquear, esquartejar e estuprar quem eles quiserem. Hoje, eles são praticamente intocáveis, visto que denunciá-los, desmoralizá-los ou acusá-los de qualquer crime é uma atitude politicamente incorreta e altamente reprovada pelo establishment progressista. A elite socialista sueca jamais se atreve a acusá-los de qualquer crime, pois temem ser classificados como xenófobos e intolerantes. Ou seja, a desgraça da Europa, sobretudo dos países escandinavos, foi não ter oferecido nenhuma resistência à ideologia progressista politicamente correta. Hoje, eles são totalmente submissos a ela.

O exemplo do Japão mostra, portanto — para além de qualquer dúvida —, a importância ética e prática da discriminação, que é perfeitamente aceitável e natural, sendo uma tendência inerente aos seres humanos, e portanto intrínseca a determinados comportamentos, sociedades e culturas.

Indo ainda mais longe nessa questão, devemos entender que na verdade todos nós discriminamos, e não existe absolutamente nada de errado nisso. Discriminar pessoas faz parte da natureza humana e quem se recusa a admitir esse fato é um hipócrita. Mulheres discriminam homens na hora de selecionar um parceiro; elas avaliam diversos quesitos, como altura, aparência, status social, condição financeira e carisma. E dentre suas opções, elas sempre escolherão o homem mais atraente, másculo e viril, em detrimento de todos os baixinhos, calvos, carentes, frágeis e inibidos que possam estar disponíveis. Da mesma forma, homens sempre terão preferência por mulheres jovens, atraentes e delicadas, em detrimento de todas as feministas de meia-idade, acima do peso, de cabelo pintado, que são mães solteiras e militantes socialistas. A própria militância progressista discrimina pessoas de forma virulenta e intransigente, como fica evidente no tratamento que dispensam a mulheres bolsonaristas e a negros de direita.

A verdade é que — não importa o nível de histeria da militância progressista — a discriminação é inerente à condição humana e um direito natural inalienável de todos. É parte indissociável da natureza humana e qualquer pessoa pode e deve exercer esse direito sempre que desejar. Não existe absolutamente nada de errado em discriminar pessoas. O problema real é a ideologia progressista e o autoritarismo politicamente correto, movimentos tirânicos que não respeitam o direito das pessoas de discriminar.

Fascismo

Quando falamos de fascismo, precisamos entender que, para a esquerda política, o fascismo é compreendido como um conceito completamente divorciado do seu significado original. Para um militante de esquerda, fascista é todo aquele que defende posicionamentos contrários ao progressismo, não se referindo necessariamente a um fascista clássico.

Mas, seja como for, é necessário entender que — como qualquer ideologia política — até mesmo o fascismo clássico tem o direito de existir e ocupar o seu devido lugar; portanto, fascistas não devem ser arbitrariamente censurados, apesar de defenderem conceitos que representam uma completa antítese de tudo aquilo que é valioso para os entusiastas da liberdade.

Em um país como o Brasil, onde socialistas e comunistas tem total liberdade para se expressar, defender suas ideologias e até mesmo formar partidos políticos, não faz absolutamente o menor sentido que fascistas — e até mesmo nazistas assumidos — sofram qualquer tipo de discriminação. Embora socialistas e comunistas se sintam moralmente superiores aos fascistas (ou a qualquer outra filosofia política ou escola de pensamento), sabemos perfeitamente que o seu senso de superioridade é fruto de uma pueril romantização universitária da sua própria ideologia. A história mostra efetivamente que o socialismo clássico e o comunismo causaram muito mais destruição do que o fascismo.

Portanto, se socialistas e comunistas tem total liberdade para se expressar, não existe a menor razão para que fascistas não usufruam dessa mesma liberdade.

É claro, nesse ponto, seremos invariavelmente confrontados por um oportuno dilema — o famoso paradoxo da intolerância, de Karl Popper. Até que ponto uma sociedade livre e tolerante deve tolerar a intolerância (inerente a ideologias totalitárias)?

As leis de propriedade privada resolveriam isso em uma sociedade livre. O mais importante a levarmos em consideração no atual contexto, no entanto — ao defender ou criticar uma determinada ideologia, filosofia ou escola de pensamento —, é entender que, seja ela qual for, ela tem o direito de existir. E todas as pessoas que a defendem tem o direito de defendê-la, da mesma maneira que todos os seus detratores tem o direito de criticá-la.

Essa é uma forte razão para jamais apoiarmos a censura. Muito pelo contrário, devemos repudiar com veemência e intransigência toda e qualquer forma de censura, especialmente a estatal.

Existem duas fortes razões para isso:

A primeira delas é a volatilidade da censura (especialmente a estatal). A censura oficial do governo, depois que é implementada, torna-se absolutamente incontrolável. Hoje, ela pode estar apontada para um grupo de pessoas cujas ideias divergem das suas. Mas amanhã, ela pode estar apontada justamente para as ideias que você defende. É fundamental, portanto, compreendermos que a censura estatal é incontrolável. Sob qualquer ponto de vista, é muito mais vantajoso que exista uma vasta pluralidade de ideias conflitantes na sociedade competindo entre si, do que o estado decidir que ideias podem ser difundidas ou não.

Além do mais, libertários e anarcocapitalistas não podem nunca esperar qualquer tipo de simpatia por parte das autoridades governamentais. Para o estado, seria infinitamente mais prático e vantajoso criminalizar o libertarianismo e o anarcocapitalismo — sob a alegação de que são filosofias perigosas difundidas por extremistas radicais que ameaçam o estado democrático de direito — do que o fascismo ou qualquer outra ideologia centralizada em governos burocráticos e onipotentes. Portanto, defender a censura, especialmente a estatal, representa sempre um perigo para o próprio indivíduo, que mais cedo ou mais tarde poderá ver a censura oficial do sistema se voltar contra ele.

Outra razão pela qual libertários jamais devem defender a censura, é porque — ao contrário dos estatistas — não é coerente que defensores da liberdade se comportem como se o estado fosse o seu papai e o governo fosse a sua mamãe. Não devemos terceirizar nossas próprias responsabilidades, tampouco devemos nos comportar como adultos infantilizados. Assumimos a responsabilidade de combater todas as ideologias e filosofias que agridem a liberdade e os seres humanos. Não procuramos políticos ou burocratas para executar essa tarefa por nós.

Portanto, se você ver um fascista sendo censurado nas redes sociais ou em qualquer outro lugar, assuma suas dores. Sinta-se compelido a defendê-lo, mostre aos seus detratores que ele tem todo direito de se expressar, como qualquer pessoa. Você não tem obrigação de concordar com ele ou apreciar as ideias que ele defende. Mas silenciar arbitrariamente qualquer pessoa não é uma pauta que honra a liberdade.

Se você não gosta de estado, planejamento central, burocracia, impostos, tarifas, políticas coletivistas, nacionalistas e desenvolvimentistas, mostre com argumentos coesos e convincentes porque a liberdade e o livre mercado são superiores a todos esses conceitos. Mas repudie a censura com intransigência e mordacidade.

Em primeiro lugar, porque você aprecia e defende a liberdade de expressão para todas as pessoas. E em segundo lugar, por entender perfeitamente que — se a censura eventualmente se tornar uma política de estado vigente entre a sociedade — é mais provável que ela atinja primeiro os defensores da liberdade do que os defensores do estado.

Machismo

Muitos elementos do comportamento masculino que hoje são atacados com virulência e considerados machistas pelo movimento progressista são na verdade manifestações naturais intrínsecas ao homem, que nossos avôs cultivaram ao longo de suas vidas sem serem recriminados por isso. Com a ascensão do feminismo, do progressismo e a eventual problematização do sexo masculino, o antagonismo militante dos principais líderes da revolução sexual da contracultura passou a naturalmente condenar todos os atributos genuinamente masculinos, por considerá-los símbolos de opressão e dominação social.

Apesar do Brasil ser uma sociedade liberal ultra-progressista, onde o estado protege mais as mulheres do que as crianças — afinal, a cada semana novas leis são implementadas concedendo inúmeros privilégios e benefícios às mulheres, aos quais elas jamais teriam direito em uma sociedade genuinamente machista e patriarcal —, a esquerda política persiste em tentar difundir a fantasia da opressão masculina e o mito de que vivemos em uma sociedade machista e patriarcal.

Como sempre, a realidade mostra um cenário muito diferente daquilo que é pregado pela militância da terra da fantasia. O Brasil atual não tem absolutamente nada de machista ou patriarcal. No Brasil, mulheres podem votar, podem ocupar posições de poder e autoridade tanto na esfera pública quanto em companhias privadas, podem se candidatar a cargos políticos, podem ser vereadoras, deputadas, governadoras, podem ser proprietárias do próprio negócio, podem se divorciar, podem dirigir, podem comprar armas, podem andar de biquíni nas praias, podem usar saias extremamente curtas, podem ver programas de televisão sobre sexo voltados única e exclusivamente para o público feminino, podem se casar com outras mulheres, podem ser promíscuas, podem consumir bebidas alcoólicas ao ponto da embriaguez, e podem fazer praticamente tudo aquilo que elas desejarem. No Brasil do século XXI, as mulheres são genuinamente livres para fazer as próprias escolhas em praticamente todos os aspectos de suas vidas. O que mostra efetivamente que a tal opressão do patriarcado não existe.

O liberalismo social extremo do qual as mulheres usufruem no Brasil atual — e que poderíamos estender a toda a sociedade contemporânea ocidental — é suficiente para desmantelar completamente a fábula feminista da sociedade patriarcal machista e opressora, que existe única e exclusivamente no mundinho de fantasias ideológicas da esquerda progressista.

Tão importante quanto, é fundamental compreender que nenhum homem é obrigado a levar o feminismo a sério ou considerá-lo um movimento social e político legítimo. Para um homem, ser considerado machista ou até mesmo assumir-se como um não deveria ser um problema. O progressismo e o feminismo — com o seu nefasto hábito de demonizar os homens, bem como todos os elementos inerentes ao comportamento e a cultura masculina — é que são o verdadeiro problema, conforme tentam modificar o homem para transformá-lo em algo que ele não é nem deveria ser: uma criatura dócil, passiva e submissa, que é comandada por ideologias hostis e antinaturais, que não respeitam a hierarquia de uma ordem social milenar e condições inerentes à própria natureza humana. Com o seu hábito de tentar modificar tudo através de leis e decretos, o feminismo e o progressismo mostram efetivamente que o seu real objetivo é criminalizar a masculinidade.

A verdade é que — usufruindo de um nível elevado de liberdades — não existe praticamente nada que a mulher brasileira do século XXI não possa fazer. Adicionalmente, o governo dá as mulheres uma quantidade tão avassaladora de vantagens, privilégios e benefícios, que está ficando cada vez mais difícil para elas encontrarem razões válidas para reclamarem da vida. Se o projeto de lei que pretende fornecer um auxílio mensal de mil e duzentos reais para mães solteiras for aprovado pelo senado, muitas mulheres que tem filhos não precisarão nem mesmo trabalhar para ter sustento. E tantas outras procurarão engravidar, para ter direito a receber uma mesada mensal do governo até o seu filho completar a maioridade.

O que a militância colorida da terra da fantasia convenientemente ignora — pois a realidade nunca corresponde ao seu conto de fadas ideológico — é que o mundo de uma forma geral continua sendo muito mais implacável com os homens do que é com as mulheres. No Brasil, a esmagadora maioria dos suicídios é praticada por homens, a maioria das vítimas de homicídio são homens e de cada quatro moradores de rua, três são homens. Mas é evidente que uma sociedade liberal ultra-progressista não se importa com os homens, pois ela não é influenciada por fatos concretos ou pela realidade. Seu objetivo é simplesmente atender as disposições de uma agenda ideológica, não importa quão divorciadas da realidade elas são.

O nível exacerbado de liberdades sociais e privilégios governamentais dos quais as mulheres brasileiras usufruem é suficiente para destruir a fantasiosa fábula da sociedade machista, opressora e patriarcal. Se as mulheres brasileiras não estão felizes, a culpa definitivamente não é dos homens. Se a vasta profusão de liberdades, privilégios e benefícios da sociedade ocidental não as deixa plenamente saciadas e satisfeitas, elas podem sempre mudar de ares e tentar uma vida mais abnegada e espartana em países como Irã, Paquistão ou Afeganistão. Quem sabe assim elas não se sentirão melhores e mais realizadas?

Homofobia

Quando falamos em homofobia, entramos em uma categoria muito parecida com a do racismo: o direito de discriminação é totalmente válido. Absolutamente ninguém deve ser obrigado a aceitar homossexuais ou considerar o homossexualismo como algo normal. Sendo cristão, não existe nem sequer a mais vaga possibilidade de que algum dia eu venha a aceitar o homossexualismo como algo natural. O homossexualismo se qualifica como um grave desvio de conduta e um pecado contra o Criador.

A Bíblia proíbe terminantemente conduta sexual imoral, o que — além do homossexualismo — inclui adultério, fornicação, incesto e bestialidade, entre outras formas igualmente pérfidas de degradação.

Segue abaixo três passagens bíblicas que proíbem terminantemente a conduta homossexual:

“Não te deitarás com um homem como se deita com uma mulher. Isso é abominável!” (Levítico 18:22 — King James Atualizada)

“Se um homem se deitar com outro homem, como se deita com mulher, ambos terão praticado abominação; certamente serão mortos; o seu sangue estará sobre eles.” (Levítico 20:13 — João Ferreira de Almeida Atualizada)

“O quê! Não sabeis que os injustos não herdarão o reino de Deus? Não sejais desencaminhados. Nem fornicadores, nem idólatras, nem adúlteros, nem homens mantidos para propósitos desnaturais, nem homens que se deitam com homens, nem ladrões, nem gananciosos, nem beberrões, nem injuriadores, nem extorsores herdarão o reino de Deus.” (1 Coríntios 6:9,10 —Tradução do Novo Mundo das Escrituras Sagradas com Referências)

Se você não é religioso, pode simplesmente levar em consideração o argumento do respeito pela ordem natural. A ordem natural é incondicional e incisiva com relação a uma questão: o complemento de tudo o que existe é o seu oposto, não o seu igual. O complemento do dia é a noite, o complemento da luz é a escuridão, o complemento da água, que é líquida, é a terra, que é sólida. E como sabemos o complemento do macho — de sua respectiva espécie — é a fêmea.

Portanto, o complemento do homem, o macho da espécie humana, é naturalmente a mulher, a fêmea da espécie humana. Um homem e uma mulher podem naturalmente se reproduzir, porque são um complemento biológico natural. Por outro lado, um homem e outro homem são incapazes de se reproduzir, assim como uma mulher e outra mulher.

Infelizmente, o mundo atual está longe de aceitar como plenamente estabelecida a ordem natural pelo simples fato dela existir, visto que tentam subvertê-la a qualquer custo, não importa o malabarismo intelectual que tenham que fazer para justificar os seus pontos de vista distorcidos e antinaturais. A libertinagem irrefreável e a imoralidade bestial do mundo contemporâneo pós-moderno não reconhecem nenhum tipo de limite. Quem tenta restabelecer princípios morais salutares é imediatamente considerado um vilão retrógrado e repressivo, sendo ativamente demonizado pela militância do hedonismo, da luxúria e da licenciosidade desenfreada e sem limites.

Definitivamente, fazer a apologia da moralidade, do autocontrole e do autodomínio não faz nenhum sucesso na Sodoma e Gomorra global dos dias atuais. O que faz sucesso é lacração, devassidão, promiscuidade e prazeres carnais vazios. O famoso escritor e filósofo francês Albert Camus expressou uma verdade contundente quando disse: “Uma só frase lhe bastará para definir o homem moderno — fornicava e lia jornais”.

Qualquer indivíduo tem o direito inalienável de discriminar ativamente homossexuais, pelo direito que ele julgar mais pertinente no seu caso. A objeção de consciência para qualquer situação é um direito natural dos indivíduos. Há alguns anos, um caso que aconteceu nos Estados Unidos ganhou enorme repercussão internacional, quando o confeiteiro Jack Phillips se recusou a fazer um bolo de casamento para o “casal” homossexual Dave Mullins e Charlie Craig.

Uma representação dos direitos civis do estado do Colorado abriu um inquérito contra o confeiteiro, alegando que ele deveria ser obrigado a atender todos os clientes, independente da orientação sexual, raça ou crença. Preste atenção nas palavras usadas — ele deveria ser obrigado a atender.

Como se recusou bravamente a ceder, o caso foi parar invariavelmente na Suprema Corte, que decidiu por sete a dois em favor de Jack Phillips, sob a alegação de que obrigar o confeiteiro a atender o “casal” homossexual era uma violação nefasta dos seus princípios religiosos. Felizmente, esse foi um caso em que a liberdade prevaleceu sobre a tirania progressista.

Evidentemente, homossexuais não devem ser agredidos, ofendidos, internados em clínicas contra a sua vontade, nem devem ser constrangidos em suas liberdades pelo fato de serem homossexuais. O que eles precisam entender é que a liberdade é uma via de mão dupla. Eles podem ter liberdade para adotar a conduta que desejarem e fazer o que quiserem (contanto que não agridam ninguém), mas da mesma forma, é fundamental respeitar e preservar a liberdade de terceiros que desejam rejeitá-los pacificamente, pelo motivo que for.

Afinal, ninguém tem a menor obrigação de aceitá-los, atendê-los ou sequer pensar que uma união estável entre duas pessoas do mesmo sexo — incapaz de gerar descendentes, e, portanto, antinatural — deva ser considerado um matrimônio de verdade. Absolutamente nenhuma pessoa, ideia, movimento, crença ou ideologia usufrui de plena unanimidade no mundo. Por que o homossexualismo deveria ter tal privilégio?

Homossexuais não são portadores de uma verdade definitiva, absoluta e indiscutível, que está acima da humanidade. São seres humanos comuns que — na melhor das hipóteses —, levam um estilo de vida que pode ser considerado “alternativo”, e absolutamente ninguém tem a obrigação de considerar esse estilo de vida normal ou aceitável. A única obrigação das pessoas é não interferir, e isso não implica uma obrigação em aceitar.

Discriminar homossexuais (assim como pessoas de qualquer outro grupo, raça, religião, nacionalidade ou etnia) é um direito natural por parte de todos aqueles que desejam exercer esse direito. E isso nem o direito positivo nem a militância progressista poderão algum dia alterar ou subverter. O direito natural e a inclinação inerente dos seres humanos em atender às suas próprias disposições é simplesmente imutável e faz parte do seu conjunto de necessidades.

Conclusão

A militância progressista é absurdamente autoritária, e todas as suas estratégias e disposições ideológicas mostram que ela está em uma guerra permanente contra a ordem natural, contra a liberdade e principalmente contra o homem branco, cristão, conservador e tradicionalista — possivelmente, aquilo que ela mais odeia e despreza.

Nós não podemos, no entanto, ceder ou dar espaço para a agenda progressista, tampouco pensar em considerar como sendo normais todas as pautas abusivas e tirânicas que a militância pretende estabelecer como sendo perfeitamente razoáveis e aceitáveis, quer a sociedade aceite isso ou não. Afinal, conforme formos cedendo, o progressismo tirânico e totalitário tende a ganhar cada vez mais espaço.

Quanto mais espaço o progressismo conquistar, mais corroída será a liberdade e mais impulso ganhará o totalitarismo. Com isso, a cultura do cancelamento vai acabar com carreiras, profissões e com o sustento de muitas pessoas, pelo simples fato de que elas discordam das pautas universitárias da moda.

A história mostra perfeitamente que quanto mais liberdade uma sociedade tem, mais progresso ela atinge. Por outro lado, quanto mais autoritária ela for, mais retrocessos ela sofrerá. O autoritarismo se combate com liberdade, desafiando as pautas de todos aqueles que persistem em implementar a tirania na sociedade. O politicamente correto é o nazismo dos costumes, que pretende subverter a moral através de uma cultura de vigilância policial despótica e autoritária, para que toda a sociedade seja subjugada pela agenda totalitária progressista.

Pois quanto a nós, precisamos continuar travando o bom combate em nome da liberdade. E isso inclui reconhecer que ideologias, hábitos e costumes de que não gostamos tem o direito de existir e até mesmo de serem defendidos.

Jan Kolčák pochádza zo stredného Slovenska a vystupuje pod umeleckým menom Deepologic. Hudbe sa venuje už viac než 10 rokov. Začínal ako DJ, ktorý s obľubou mixoval klubovú hudbu v štýloch deep-tech a afrohouse. Stále ho ťahalo tvoriť vlastnú hudbu, a preto sa začal vzdelávať v oblasti tvorby elektronickej hudby. Nakoniec vydal svoje prvé EP s názvom "Rezonancie". Učenie je pre neho celoživotný proces, a preto sa neustále zdokonaľuje v oblasti zvuku a kompozície, aby jeho skladby boli kvalitné na posluch aj v klube.

V roku 2023 si založil vlastnú značku EarsDeep Records, kde dáva príležitosť začínajúcim producentom. Jeho značku podporujú aj etablované mená slovenskej alternatívnej elektronickej scény. Jeho prioritou je sloboda a neškatulkovanie. Ako sa hovorí v jednej klasickej deephouseovej skladbe: "We are all equal in the house of deep." So slobodou ide ruka v ruke aj láska k novým technológiám, Bitcoinu a schopnosť udržať si v digitálnom svete prehľad, odstup a anonymitu.

V súčasnosti ďalej produkuje vlastnú hudbu, venuje sa DJingu a vedie podcast, kde zverejňuje svoje mixované sety. Na Lunarpunk festivale bude hrať DJ set tvorený vlastnou produkciou, ale aj skladby, ktoré sú blízke jeho srdcu.

AI hype vnímame asi všetci okolo nás — už takmer každá appka ponúka nejakú “AI fíčuru”, AI startupy raisujú stovky miliónov a Európa ako obvykle pracuje na regulovaní a našej ochrane pred nebezpečím umelej inteligencie. Pomaly sa ale ukazuje “ovocie” spojenia umelej inteligencie a človeka, kedy mnohí ľudia reportujú signifikantné zvýšenie produktivity v práci ako aj kreatívnych aktivitách (aj napriek tomu, že mnohí hardcore kreatívci by každého pri spomenutí skratky “AI” najradšej upálili). V prvej polovici prednášky sa pozrieme na to, akými rôznymi spôsobmi nám vie byť AI nápomocná, či už v práci alebo osobnom živote.

Umelé neuróny nám už vyskakujú pomaly aj z ovsených vločiek, no to ako sa k nám dostávajú sa veľmi líši. Hlavne v tom, či ich poskytujú firmy v zatvorených alebo open-source modeloch. V druhej polovici prednášky sa pozrieme na boom okolo otvorených AI modelov a ako ich vieme využiť.

High Prairie

**One **

Let's sit down here, all of us, on the open prairie, where we can't see a highway or a fence. Let's have no blankets to sit on, but feel the ground with our bodies, the earth, the yielding shrubs. Let's have the grass for a mattress, experiencing its sharpness and its softness. Let us become like stones, plants, and trees. Let us be animals, think and feel like animals.1

Listen to the air. You can hear it, feel it, smell it, taste it. Woniya wakan--the holy air-- which renews all by its breath. Woniya, woniya wakan-- spirit, life, breath, renewal--it means all that. Woniya--we sit together, don't touch, but something is there; we feel it between us, as a presence. A good way to start thinking about nature, talk about it. Rather talk to it, talk to the rivers, to the lakes, to the winds as to our relatives.1

There it went again. Kind of halfway between a gobble and a drumming. Or perhaps both sounds. I was just coming ou of a restful, deep sleep. A dim, orange light filtered throug the tent's rain-fly.

Gobble-gobble-drum-gobble, drum. The strange sound mingled for a moment with my dreams, then became reality. I sat up in my sleeping bag. Cold morning air hit my face.

Gobble, drum-gobble, drum. The sounds were everywhere now. "What in the world is going on?", I thought. Things were getting quite wild. This drumming, gobbling sound filled the air on all sides around me, with the sounds growing louder and more numerous. I was in the tent, wrapped in my sleeping bag, unable to move much, and not able to see the

---2

strange goings-on outside. It was all kind of crazy and wonderful, and I felt very curious and left out. What was going on?

I quietly unzipped my down bag, and slipped out. Likewise, I opened the tent door, then with a sudden and quick jerk on the rain fly zipper, I opened the tent to the outside world, and plunged out onto my belly, glancing all around in an effort to catch a glimpse of whatever it was that had, in such an unusual way, brought me to wakefulness.

Tens of flapping wings beat the air, and the sky around me filled with sharp-tailed grouse. The birds took off to the east--flapping their wings, gliding: flapping, gliding. Then all was still and quiet again, save for the occassional moo of a cow in some far pasture, and I was alone on the high prárie, in the chill of morning, with the golden light of dawn growing around me as the sun edged up toward the eastern horizon.

I was laughing with delight. In the city you get woken up by an alarm clock--by a warning, that says you'd better get up, or be late for work, or school, or whatever you're in danger of being late for. Here in the country its different. You're woken up by the wonders of the new day. "How dare they wake me up like that", I joked out loud. "On the other hand", I thought, "I was sleeping right in the middle of their dancing ground." I was awake and happy, stretched half-way out of the tent door with my stomach lying on the short, dry

---3

grass of the southeast Montana prairie.

The honey was thick. I spread it over peanut butter and bread with my hunting knife, then sat back and enjoyed breakfast while watching the sunlight begin to rake the hilltops. This was Antelope Valley--or so I had named it, after the small herd of seven or eight antelope that frequented the area. I was down in the bottom of this broad, shallow valley now, but if you walked up to the top of any of the surrounding hills, you could see the vastness of the high prarie. The land rolled away from you towards the horizon. Bare, slate-covered hilltops, lush, green grass and clover in the draws. Dandelions and chokecherry bushes backlighted by the low-lying morning sun. Gravelly hillsides in the distance, streaked with brown, red, and sometimes black.

And therin lies a problem. Those black streaks. The pratie, it seems, overlies huge beds of coal. Coal that is needed by society. Coal that must be mined to feed our technology. Dirty, black rock that is blasted and gouged out of the earth by some of the largest, most powerful machinery ever built by mankind.

I thought about this as I chewed on dry apricots. The line between sunlight and shadow, still to my west, moved rapidly now, towards where I sat. I looked forward to the sun.

The original natives of this land, the plains indians, would never have understood and condoned what the white man was doing to the prarie. To them, digging up the earth--

---4

taking a blade to the earth--was "like taking a knife to my mother's breast". I sat there in the grass, my hunger satisfied and the soft sunlight just beginning to hit my face, and I knew that I agreed with the indians.

Two The Broken Hoop

I shouldered my day pack and took off to the northeast, up a draw. Three antelope appeared on the crest of the hill to my left. When they saw me they froze, alert and ready to dash off at the slightest hint of danger. I froze too, so as not to scare them away. These mammals were at home here on the prairie. Mile upon mile of vast, open space--perfect habitat for a species which depends on early warning and tremendous speed to escape from predators. I had often, during my hiking trips on the prairie, tried to sneak up on antelope, and see how close I could come to them. It was difficult, to say the least. "Hunting antelope with bow and arrow must have been an art", I thought. The sun grew warmer. I pulled off my wool sweater and walked to the top of the hill.

What would it have been like to have been an indian before the white man came? And what would it have been like to have been conquered by the wasichus, and seen your beloved land taken away from you, then despoiled and abused by an uncontrolled technology? The indians had technologies, you know. Arrows, bone awls, fire--these are all technologies, even if they are 'primitive'. And fire alone is enough of a technology to wreak tremendous destruction on an environment.

---7

Nuclear bombs only do the job much quicker. Yes, the indians, like us, had technology, and it was advancing, although surely at a relatively slow pace. Unlike us, however, they lived in harmony with the Earth. The rational and irrational within indian society were in balance, and as a result, the people had a peace of mind. What would it have been like to have lived as an indian? Perhaps some of Black Elk's accounts

relate this best:

Once we were happy in our own country and we were seldom hungry, for then the two-leggeds and the four-leggeds lived together likę relatives, and there was plenty for them and for us. 2

That was another happy summer, for the big trouble had not come yet. We cut plenty of tepee poles up along the creeks that came down the east side of the Black Hills, and there was all we wanted to eat, for the Hills were like a big food pack for our people. Iron Bull, a little boy my age, and I had great fun fishing. We always made an offering of bait to the fish, saying: "You who are down in the water with wings of red, I offer this to you: so come hither." Then when we caught the first fish, we would put it on a forked stick and kiss it. If we did not do this, we were sure the others would know and stay away. If we caught a little fish, we would kiss it and throw it back, so that it would not go and frighten the bigger fish. I don't know whether all this helped or not, but we always got plenty of fish, and our parents were proud of us. We tried to catch as many as we could so that people would think much of us. 3

The sun, the Light of the world, I hear Him coming. I see His face as He comes. He makes the beings on earth happy. And they rejoice. O Wakan-Tanka, I offer to You this world of Light.4

But the Wasichus came, and they have made little islands for the four-leggeds, and always these islands are becoming smaller, for around them surges the gnawing flood of the Wasichu, and it is dirty with lies and greed.5

---8

I did not know then how much was ended. When I look back now from this high hill of my old age, I can still see the butchered women and children lying heaped and scattered all along the crooked gulch as plain as when I saw them with eyes still young. And I can see that something else died there in the bloody mud, and was buried in the blizzard. A people's dream died there. It was a beautiful dream.

And I, to whom so great a vision was given in my youth,--you see me now a pitiful old man who has done nothing, for the nation's hoop is broken and scattered. There is no center any longer, and the sacred tree is dead. 6

A light and pleasantly cool west wind fortold of a fine, spring day. I sat on top of the hill, overlooking Antelope Valley and the prairie beyond. I hadn't known the name for it then, but I was looking at the World's Rim. I remember sitting there in the sunshine thinking that it should be so easy to live as one with all that surrounded me.

But it isn't. Its hard to live in this society, and to achieve a 'peace of mind', to be as one with the universe. We (western society) have destroyed an entire culture. And my god, what have we replaced it with??

I was back in the stockroom loading huge boxes of 4-ply toilet tissue onto a trolley when the call came. "Employee four to TA, four to TA". That was me--number four. I heaved a last box onto the cart, and started off for the toiletries section.

The store was getting crowded now. Sundays at K-Mart were

---9

like that. I passed by the plastic dishpans and turned left. Through the windows at the front of the store, I could see that it was snowing. "What do the mountains look like now?", I thought. The mountains, rugged and snow-capped, lay only a few miles to the north. But from inside the store, one could only see the parking lot.

She seemed upset. "Foamy menthol is advertised as on sale", she explained, "but there's none left on the shelft"

"A catastrophe", I thought, sarcastically.

"Oh I'm very sorry", I replied, as sincerely as possible. "And I'm sure we don't have any in back, either. Would you like a rain check?"

"Oh, well--no". She was kind of grumbling. I like the menthol so much. You get in a hot shower, and then rub it all over your body, and you just tingle all over. It feels so good".

I didn't know quite what to say, so I just nodded and went back to work stocking the shelves with toilet paper. Business was still picking up. The air was heavy with the smell of paper, popcorn, people, and a thousand other oders from a thousand different products. Kids screamed and piloted plastic spaceships down the isles of the toy section. Two teenage boys stood gaping at a Farrah Fawcet poster.

And outside, the snow--and beyond that, the mountains...

---Three The Yin and the Yang

A red-tailed hawk soared on a rising thermal. It was early still, but already getting hot. This was a land of extremes. On the high prairie, it could be sunny and warm one minute, snowing and bitter cold the next. Yet I loved it there, out in the open, empty space all around me. It was alot like the desert--vast, seemingly endless distances. A landscape where your conscienceness has room to expand out and fill the spaces, where you have freedom to think and feel and grow. It is a landscape that you become a part of.

Paula Gunn Allen talks about the feeling of wholeness that permeates Native American thought.

...At base, every story, every song, every ceremony, tells the Indian that he is part of a living whole, and that all parts of that whole are related to one another by virtue of their participation in the whole of being.7

Allen also speaks of the "dualistic division that the white man imposes on the rational--irrational aspects of the universe:

...Native American thought makes no such dualistic division, nor does it draw a hard-and-fast line between what is material and what is spiritual, for the two are seen to be two expressions of the same reality--as though life has twin manifestations that are mutually interchangeable and, in many instances, virtually identical aspects of a reality that is, essentially, more spirit than matter, or that more correctly, manifests its very spiritness in a tangible

---11

way. The closest analogy in western thought is the Einsteinian understanding of matter as a special state or condition of energy. Yet even this concept falls short of the Native American understanding, for Einsteinian energy is essentially stupid, while energy in the Indian view is intelligence manifesting yet another way.8

This indian philosophy is indeed a beautiful one; "...energy in the Indian view is intelligence manifesting yet another way". The idea of wholeness of the universe, of the inter- relatedness of everything permeates all of indian thought. This feeling of wholeness of the universe is something that touched me, during my wanderings out on the Montana prairie. It is a peace of mind, that the indians achieved through

song, dance, ceremony, and living close to the earth.

Allen made one statement, however, that was a bit short- sighted, "... Einsteinian energy is essentially stupid...". I don't believe Einstein thought of his energy as stupid. Dr. Einstein had a sense of the mystical in life, and he speaks about it in the following passager

The most beautiful and most profound emotion we can experience is the sensation of the mystical. It is the source of all true science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead. To know that what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty which our dull faculties can comprehend only in their most primitive forms--this knowledge, this feeling is at the center of true religiousness.9

Indeed, modern physics is tending more and more towards theories that are complementary to philosophies like that of eastern mysticism and american indian. Energy is no longer being viewed as "stupid". Fritjof Capra speaks of this in his

---12

book, "The Tao of Physics".

...I see science and mysticiom as two complement- ary manifestations of the human mind, of its rational and intuitive faculties. The modern physicist ex- periences the world through an extreme specialization of the rational mind, the mystic through an extreme specialization of the intuitive mind. The two approaches are entirely different and involve far more than a certain view of the physical world. However, they are complementary, as we have learned to say in physics. Neither is comprehended in the other, nor can either of them be reduced to the other, but both of them are necessary, supplementing one another for a fuller understanding of the world. To paraphrase an old Chinese saying, mystics understand the roots of the Tao but not its branches, scientists understand its branches but not its roots. Science does not need mysticism and mysticism does not need science: but man needs both. Mystical experience is necessary to understand the deepest nature of things, and science is essential for modern life. What we need, therefore, is not a synthesis but a dynamic interplay between mystical intuition and scientific analysis.10

Capra believes, as I so, that our society "...is too yang --too rational, male, and aggressive". Our culture today lacks the balance between the yin and the yang. We are failing to see the wholeness of the universe. Our culture does view energy as something stupid, even though our science is beginning to tell us otherwise. We fail to see that the universe is moving, breathing, and alive--and that we are a part of it.

I believe that the world view implied by modern physics is inconsistent with our present society, which does not reflect the harmonious interrelatedness we observe in nature. To achieve such a state of dynamic balance, a radically different social and economic structure will be needed a cultural revolution in the true sense of the word. The survival of our whole civilization may depend on whether we can bring about such a change. It will depend, ultimately, on our ability to adopt some of the vin attitudes of Eastern mysticism; to experience the wholeness of nature and the art of living with it in harmony. 11

---13

Four Ghosts

So what about the american indian? How does he fit into all of this? Well, perhaps he can help show us the way--perhaps we can learn something from the indians. Even though its probably too late for the resurgence of indian societies like those of the past, perhaps we can all (i.e. all modern societies), through an attempt at understanding the indian and his lifestyle, learn about the intrinsic interplay of the yin and the yang in our universe, and as Capra says, "experience the wholeness of nature and the art of living with it in harmony".

Ray Bradbury's "The Martian Chronicles" is the story of one culture (Earth's) moving in and displacing another (the Martian's)--a story which bears a high degree of resemblance with white man--indian history. In the following exerpts from this book, Tomás Gomez, a relative newcomer to the already established colonies on Mars, meets a Martian:

Now he looked at the Martian against the sky.

"The stars!" he said. "The stars!" said the Martain, looking, in turn,

at Tomás. The stars were white and sharp beyond the flesh on the Martain, and they were sewn into his flesh like scintillas swallowed into the thin, phosphor- escent membrane of a gelatinous sea fish. You could see stars flickering like violet eyes in the Martian's stomach and chest, and through his wrists, like

jewelry. "I can see through you!" said Tomas.

---14

back. "And I through youl" said the Martian, stepping Tomás felt of his own body and, feeling the warmth, was reassured. I am real, he thought. The Martian touched his own nose and lips. "I have flesh," he said, half aloud. "I am alive." Tomás stared at the stranger. real, then you must be dead." "And if I am "No, you!" "A ghost!" "A phantom!" They pointed at each other, with starlight burning in their limbs like daggers and icicles and fireflies, and then fell to judging their limbs again, each finding himself intact, hot, excited, stunned, awed, and the other, ah yes, that other over there, unreal, a ghostly prism flashing the accumulated light of distant worlds.12

"There are the rockets." Tomás walked him to the edge of the hill and pointed down. "See?"

"No."

"Damn it, there they are! Those long silver things."

"No."

Now Tomás laughed. "You're blind!"

"I see very well. You are the one who does not see."

"But you see the new town, don't you?'

"I see nothing but an ocean, and water at low

tide."

"Mister, that water's been evaporated for forty centuries."

"Ah, now, now, that is enough." "It's true, I tell you,

"No, you are from the Past," said the Earth Man, having had time to think of it now.

"You are so certain. How can you prove who is form the Past, who from the Future? What year is it?"

"Two thousand and one!"

"What does that mean to me?"

Tomas considered and shrugged. "Nothing."

"It is as if I told you that it is the year 4462853 S.E.C. It is nothing and more than nothing! Where is the clock to show us how the stars stand?"

"But the ruins prove it! They prove that I am the Future, I am alive, you are dead!"

"Everything in me denies this. My heart beats, my stomach hungers, my mouth thirsts. No, no, not dead, not alive, either of us. More alive than

---15

anything else. Caught between is more like it. Two strangers passing in the night, that is it.

Two strangers passing. Ruins, you say?" "Yes. You're afraid?"14"

Tomás put out his hand. The Martian did likewise in imitation. Their hands did not touch; they melted through

each other.

"Will we meet again?"

"Who knows? Perhaps some other night." "I'd like to go with you to that festival."

"And I wish I might come to your new town, to see this ship you speak of, to see these men, to hear all that has happened."

"Good-by," said Tomas.

"Good night."

The Martian rode his green metal vehicle quietly away into the hills, The Earth Man turned his truck and drove it silently in the opposite direction.

"Good lord, what a dream that was," sighed Tomás, his hands on the wheel, thinking of the rockets, the women, the raw whisky, the Virginia reels, the party.

How strange a vision was that, thought the Martian, rushing on, thinking of the festival, the canals, the boats, the women with golden eyes, and the songs. The night was dark. The moons had gone down.

Starlight twinkled on the empty highway where now there was not a sound, no car, no person, nothing. And it remained that way all the rest of the cool dark night. 15

Perhaps our two cultures--the white man's and the indian's-- are like these two 'ghosts in the night'--each different, each moving a different direction in time, and each leaving the encounter with a feeling of the essence of the other. Whereas the indians can now only look back at the past, the white man must look toward the future. We can only hope that our cultural encouter with the american indian will someday be looked on as a learning experience for us---an experience where part of the essence of the indian way of life has rubbed off on us.

Indeed, the american indian, as he truely existed, now

---16

stands in the past. I believe, that if we are to survive in a meaningful and wholesome way, than we must carry a part of the indian into the future with us. Perhaps the most encouraging thought of all is, that we probably can't avoid carrying the indian philosophies into the future with us, at least in part. After all, we have literature on and by indians, and some people are reading it. We have remnants of indian tribes scattered throughout this country, and some people are learning something of the old ways from them. He will always be with us. The indian is now in our history. Indeed, as Seattle once put it,

"The White Man will never be alone."

...And when the last Red Man shall have perished, and the memory of my tribe shall have become a myth among the White Men, these shores will swarm with the invisible dead of my tribe, and when your children's children think themselves alone in the field, the store, the shop, upon the highway, or in the silence of the pathless woods, they will not be alone. At night when the streets of your cities and villages are silent and you think them deserted, they will throng with the returning hosts that once filled and still love this beautiful land. The White Man will never be alone. Let him be just and deal kindly with my people, for the dead are not powerless. Dead, did I say? There is no death, only a change of worlds.16

The hawk I had been watching earlier drifted slowly with the wind towards the eastern horizon, then disappeared behind a far ridge. A wispy patch of cirrus clouds stood out glaring and bright-white in an otherwise electric-blue sky. Down the hill and to the left of me, an albino porcupine was digging for something around an area of deadfall and

---17

ponderosa pine trees. It was springtime on the prairie, and the whole world there was alive, growing, and at peace. It was a reminder of what our future could be.

Hey everyone,

I owe you some photos from my Moshi walk! I know, I know, I’ve been promising them for days. The truth is, I’ve been caught up in the digital world. I’ve been sorting through photos and diving deep into my Telos account. I’m really interested in exploring its potential, but it’s been a bit of a time-suck.

Then, today, I remembered my old friend: EOS. This is my fourth EOS account, and guess what? The same old problems. Not enough CPU! I thought I had figured out this whole CPU thing – use it, it goes down; don’t use it, it goes up. But nope, not this time. It won’t even let me power up. I’ve spent the whole day trying to fix it, but I’m officially tapped out. If anyone has any magic solutions, please share!

On a brighter note, I had lunch at a real local spot today. Not the cleanest place, but the food was cheap and authentic. Definitely a local experience! May I have no regrets about this.

Oh, and speaking of local experiences, Kilimanjaro is finally peeking out from the clouds! I’m about to snap a photo to share. I promised to share more photos of my Moshi walk, and in this post you will see them. I’m extending my stay here, so I’ll have more time to explore and figure out my next move.

Stay tuned for more updates! And if you have any tips on Telos or EOS, please drop a comment below.

Until next time, take it easy and don’t stress too much!

Kilimanjaro was being shy today. No photo, unfortunately.

Photos from my Moshi walk, taken two days ago.

Podnikanie je jazyk s "crystal clear" pravidlami. Inštrumentalisti vidia podnikanie staticky, a toto videnie prenášajú na spoločnosť. Preto nás spoločnosť vníma často negatívne. Skutoční podnikatelia sú však "komunikátori".

The concept of Artificial Space Track is inspired by the power of humanity, which has been creating an intelligent space around itself for millennia. This space serves to connect communication networks that unite humanity into a single organism. It represents a symbiosis between technology and society, where information and communication seamlessly intertwine, allowing us to better understand the world and collaborate more effectively. This concept opens up new possibilities and creates space for innovation and progress

The song “Extraterrestrial Biological Entity” delves into the exploration of the universe and the search for extraterrestrial civilizations. It poses the question: Are we alone in the cosmos? This track inspires us to contemplate our place in the infinite universe and seek answers to these mysterious questions

The concept of the Holographic Universe explores the idea that our perceived universe might be a 2D projection from a deeper, multi-dimensional space. According to this theory, we could be akin to holograms existing on the surface of an infinitely distant horizon. This concept raises questions about the nature of reality, information, and the boundaries of our understanding. It’s a fascinating idea that prompts us to contemplate the deeper layers of the cosmos and our existence

The track “How does the universe work?” delves into the question of how the universe functions and why it exists at all. This track inspires us to contemplate the nature of the universe, its laws, and our role within it.

Why relay hints are important

Recently Coracle has removed support for following relay hints in Nostr event references.

Supposedly Coracle is now relying only on public key hints and kind:10002 events to determine where to fetch events from a user. That is a catastrophic idea that destroys much of Nostr's flexibility for no gain at all.

• Someone makes a post inside a community (either a NIP-29 community or a NIP-87 community) and others want to refer to that post in discussions in the external Nostr world of kind:1s -- now that cannot work because the person who created the post doesn't have the relays specific to those communities in their outbox list;
• There is a discussion happening in a niche relay, for example, a relay that can only be accessed by the participants of a conference for the duration of that conference -- since that relay is not in anyone's public outbox list, it's impossible for anyone outside of the conference to ever refer to these events;
• Some big public relays, say, relay.damus.io, decide to nuke their databases or periodically delete old events, a user keeps using that big relay as their outbox because it is fast and reliable, but chooses to archive their old events in a dedicated archival relay, say, cellar.nostr.wine, while prudently not including that in their outbox list because that would make no sense -- now it is impossible for anyone to refer to old notes from this user even though they are publicly accessible in cellar.nostr.wine;
• There are topical relays that curate content relating to niche (non-microblogging) topics, say, cooking recipes, and users choose to publish their recipes to these relays only -- but now they can't refer to these relays in the external Nostr world of kind:1s because these topical relays are not in their outbox lists.
• Suppose a user wants to maintain two different identities under the same keypair, say, one identity only talks about soccer in English, while the other only talks about art history in French, and the user very prudently keeps two different kind:10002 events in two different sets of "indexer" relays (or does it in some better way of announcing different relay sets) -- now one of this user's audiences cannot ever see notes created by him with their other persona, one half of the content of this user will be inacessible to the other half and vice-versa.
• If for any reason a relay does not want to accept events of a certain kind a user may publish to other relays, and it would all work fine if the user referenced that externally-published event from a normal event, but now that externally-published event is not reachable because the external relay is not in the user's outbox list.
• If someone, say, Alex Jones, is hard-banned everywhere and cannot event broadcast kind:10002 events to any of the commonly used index relays, that person will now appear as banned in most clients: in an ideal world in which clients followed nprofile and other relay hints Alex Jones could still live a normal Nostr life: he would print business cards with his nprofile instead of an npub and clients would immediately know from what relay to fetch his posts. When other users shared his posts or replied to it, they would include a relay hint to his personal relay and others would be able to see and then start following him on that relay directly -- now Alex Jones's events cannot be read by anyone that doesn't already know his relay.

How to do curation and businesses on Nostr

Suppose you want to start a Nostr business.

You might be tempted to make a closed platform that reuses Nostr identities and grabs (some) content from the external Nostr network, only to imprison it inside your thing -- and then you're going to run an amazing AI-powered algorithm on that content and "surface" only the best stuff and people will flock to your app.

This will be specially good if you're going after one of the many unexplored niches of Nostr in which reading immediately from people you know doesn't work as you generally want to discover new things from the outer world, such as:

• food recipe sharing;
• sharing of long articles about varying topics;
• markets for used goods;
• freelancer work and job offers;
• specific in-game lobbies and matchmaking;
• directories of accredited professionals;
• sharing of original music, drawings and other artistic creations;
• restaurant recommendations
• and so on.

But that is not the correct approach and damages the freedom and interoperability of Nostr, posing a centralization threat to the protocol. Even if it "works" and your business is incredibly successful it will just enshrine you as the head of a platform that controls users and thus is prone to all the bad things that happen to all these platforms. Your company will start to display ads and shape the public discourse, you'll need a big legal team, the FBI will talk to you, advertisers will play a big role and so on.

If you are interested in Nostr today that must be because you appreciate the fact that it is not owned by any companies, so it's safe to assume you don't want to be that company that owns it. So what should you do instead? Here's an idea in two steps:

1. Write a Nostr client tailored to the niche you want to cover

If it's a music sharing thing, then the client will have a way to play the audio and so on; if it's a restaurant sharing it will have maps with the locations of the restaurants or whatever, you get the idea. Hopefully there will be a NIP or a NUD specifying how to create and interact with events relating to this niche, or you will write or contribute with the creation of one, because without interoperability none of this matters much.

The client should work independently of any special backend requirements and ideally be open-source. It should have a way for users to configure to which relays they want to connect to see "global" content -- i.e., they might want to connect to wss://nostr.chrysalisrecords.com/ to see only the latest music releases accredited by that label or to wss://nostr.indiemusic.com/ to get music from independent producers from that community.

1. Run a relay that does all the magic

This is where your value-adding capabilities come into play: if you have that magic sauce you should be able to apply it here. Your service, let's call it wss://magicsaucemusic.com/, will charge people or do some KYM (know your music) validation or use some very advanced AI sorcery to filter out the spam and the garbage and display the best content to your users who will request the global feed from it (["REQ", "_", {}]), and this will cause people to want to publish to your relay while others will want to read from it.

You set your relay as the default option in the client and let things happen. Your relay is like your "website" and people are free to connect to it or not. You don't own the network, you're just competing against other websites on a leveled playing field, so you're not responsible for it. Users get seamless browsing across multiple websites, unified identities, a unified interface (that could be different in a different client) and social interaction capabilities that work in the same way for all, and they do not depend on you, therefore they're more likely to trust you.

---

Does this centralize the network still? But this a simple and easy way to go about the matter and scales well in all aspects.

Besides allowing users to connect to specific relays for getting a feed of curated content, such clients should also do all kinds of "social" (i.e. following, commenting etc) activities (if they choose to do that) using the outbox model -- i.e. if I find a musician I like under wss://magicsaucemusic.com and I decide to follow them I should keep getting updates from them even if they get banned from that relay and start publishing on wss://nos.lol or wss://relay.damus.io or whatever relay that doesn't even know what music is.

The hardcoded defaults and manual typing of relay URLs can be annoying. But I think it works well at the current stage of Nostr development. Soon, though, we can create events that recommend other relays or share relay lists specific to each kind of activity so users can get in-app suggestions of relays their friends are using to get their music from and so on. That kind of stuff can go a long way.

About Nostr, email and subscriptions

I check my emails like once or twice a week, always when I am looking for something specific in there.

Then I go there and I see a bunch of other stuff I had no idea I was missing. Even many things I wish I had seen before actually. And sometimes people just expect and assume I would have checked emails instantly as they arrived.

It's so weird because I'm not making a point, I just don't remember to open the damn "gmail.com" URL.

---

I remember some people were making some a Nostr service a while ago that sent a DM to people with Nostr articles inside -- or some other forms of "subscription services on Nostr". It makes no sense at all.

Pulling in DMs from relays is exactly the same process (actually slightly more convoluted) than pulling normal public events, so why would a service assume that "sending a DM" was more likely to reach the target subscriber when the target had explicitly subscribed to that topic or writer?

Maybe due to how some specific clients work that is true, but fundamentally it is a very broken assumption that comes from some fantastic past era in which emails were 100% always seen and there was no way for anyone to subscribe to someone else's posts.

Building around such broken assumptions is the wrong approach. Instead we should be building new flows for subscribing to specific content from specific Nostr-native sources (creators directly or manual or automated curation providers, communities, relays etc), which is essentially what most clients are already doing anyway, but specifically Coracle's new custom feeds come to mind now.

---

This also reminds me of the interviewer asking the Farcaster creator if Farcaster made "email addresses available to content creators" completely ignoring all the cryptography and nature of the protocol (Farcaster is shit, but at least they tried, and in this example you could imagine the interviewer asking the same thing about Nostr).

I imagine that if the interviewer had asked these people who were working (or suggesting) the Nostr DM subscription flow they would have answered: "no, you don't get their email addresses, but you can send them uncensorable DMs!" -- and that, again, is getting everything backwards.

Nostr is not decentralized nor censorship-resistant

Peter Todd has been saying this for a long time and all the time I've been thinking he is misunderstanding everything, but I guess a more charitable interpretation is that he is right.

Nostr today is indeed centralized.

Yesterday I published two harmless notes with the exact same content at the same time. In two minutes the notes had a noticeable difference in responses:

The top one was published to wss://nostr.wine, wss://nos.lol, wss://pyramid.fiatjaf.com. The second was published to the relay where I generally publish all my notes to, wss://pyramid.fiatjaf.com, and that is announced on my NIP-05 file and on my NIP-65 relay list.

A few minutes later I published that screenshot again in two identical notes to the same sets of relays, asking if people understood the implications. The difference in quantity of responses can still be seen today:

These results are skewed now by the fact that the two notes got rebroadcasted to multiple relays after some time, but the fundamental point remains.

What happened was that a huge lot more of people saw the first note compared to the second, and if Nostr was really censorship-resistant that shouldn't have happened at all.

Some people implied in the comments, with an air of obviousness, that publishing the note to "more relays" should have predictably resulted in more replies, which, again, shouldn't be the case if Nostr is really censorship-resistant.

What happens is that most people who engaged with the note are following me, in the sense that they have instructed their clients to fetch my notes on their behalf and present them in the UI, and clients are failing to do that despite me making it clear in multiple ways that my notes are to be found on wss://pyramid.fiatjaf.com.

If we were talking not about me, but about some public figure that was being censored by the State and got banned (or shadowbanned) by the 3 biggest public relays, the sad reality would be that the person would immediately get his reach reduced to ~10% of what they had before. This is not at all unlike what happened to dozens of personalities that were banned from the corporate social media platforms and then moved to other platforms -- how many of their original followers switched to these other platforms? Probably some small percentage close to 10%. In that sense Nostr today is similar to what we had before.

Peter Todd is right that if the way Nostr works is that you just subscribe to a small set of relays and expect to get everything from them then it tends to get very centralized very fast, and this is the reality today.

Peter Todd is wrong that Nostr is inherently centralized or that it needs a protocol change to become what it has always purported to be. He is in fact wrong today, because what is written above is not valid for all clients of today, and if we drive in the right direction we can successfully make Peter Todd be more and more wrong as time passes, instead of the contrary.

Lessons from the Tao Te Ching Leading to a Stress-Free Life

"Hun," said my wife through gritted teeth.

I saw her, sure. I heard her too, but my mind didn't stop. My eyes tracked my daughter as she prowled the living room, giggling as she tossed things from tables and shelves.

"John!"

I whipped around. My wife shook her leg in mid-air, flinging my clinging son's feet and said, "Please distract your son while I finish cooking."

I had taken my glare off my daughter for too long. I didn't notice the Lego block that was mid-trajectory toward my head. I stood to save my wife from my son and shifted the path of contact. I took two steps, and the Lego, once destined for my head, ended up under my foot. I slipped and dove past my wife.

"I got him," I said, sprawled out across the floor as I removed my son from my wife's leg.

The chaos continued through dinner. My wife and I exchanged weary glances between spoonfuls and tag-teamed the kids to stave off their hunger. Then, we embarked on the nighttime routine.

It's a blessing we've managed to get our kids accustomed to going down by 8 pm. My wife and I built that schedule to carve out some time for ourselves and for the house. Since the arrival of our glorious children, our house has been in constant disarray. However, every time my wife and I sneak out of the children's rooms once they've been put to sleep, we're spent. The sight of our messy house is demoralizing. Rather than clean, we cower in our bed, cuddled up next to one another, and dive into our social media. We doom scroll until our eyes droop closed.

I've never been very good at keeping up with my house, even before the kids. I'd let dishes pile up, but I'd wash them before the day was out. With kids, the dishes pile up and never get cleaned until it gets out of hand.

The dishes illustrate everything else around me. The grass gets cut when I notice my dog entering the house with a bunch of hitchhiker weeds. The clothes get put away from the laundry room when my drawers are empty and I can't find what to wear. Time is a slippery thing for me. I thought I'd be getting more of it back when I made the decision to start my own business. Who was I kidding? Now, when I have a few moments to spare, I have to choose whether I want to get ahead on my "honey-do" list at home or lay my head back and catch a breath from my fast-paced life.

Small issues grew into catastrophes. Missing shingles led to leaks in the ceiling after a heavy storm. Not changing the filter in the AC led to having to replace the whole unit. A constantly messy house led to unease and embarrassment in front of friends and family. I had never placed much importance on taking care of the little things because I felt I was taking care of what mattered. I convinced myself that working non-stop on my business and bringing money to the household would solve everything. When I wasn't focused on my business, I was trying to be the "best" dad ever by choosing to play with my kids over doing things that needed to be done around the house. I wasn't enforcing the need to pick up after play. I wasn't leading my kids by example through the actions I was taking (or ignoring) about the maintenance of the things my family owned.

It wasn't until I experienced a bundle of financial emergencies and was forced to ask my mother for a bailout that I realized it was high time for a change.

After handing me the money I needed, my mother told me, "John, you know I'll always help you when you need it, but you need to help yourself. Take care of your things and be the man of the house, or someone else will soon take your place."

I couldn't believe my mother would tell me that. Her words echoed her past, harking back to the day she and my father divorced. I thought to myself, my wife and I were nothing like my parents. We have a powerful relationship, and I'd always worked hard to keep deepening that relationship precisely because I didn't want to end up like my parents.

Then it hit me. My mother was right. My anger simmered away. If I had just treated the things I owned and the people I knew like I treated my relationship with my wife, I would have never been in that predicament.

I deep-cleaned the house that day as a declaration of new habits to come. As I was dusting the bookshelf, I noticed a little book I had read years ago in college: the Tao Te Ching (Dào Dé Jīng).

I stared at the title of the book written across the spine for a moment. I vaguely remembered its core tenets, but everything that had happened up until then compelled me to pull it out of the bookshelf and revisit its wise words. Much like what the Tao Te Ching instructs, taking care of the things you have, giving them longevity, aligns you to the natural order of the universe and allows you to live in better harmony with yourself and the world.

Words of an Ancient Sage

Long ago, in ancient China, Yinxi stood, broad-shouldered and clad in leather armor, before the arc of the Hangu Pass. The sun was setting on the horizon when a familiar face appeared.

Laozi was on his way to a life of seclusion, seeking passage to Mount Zhongnan. Society, plagued by moral decay and the conflicting ambitions of the political elite, threatened to ignite generational conflict. Laozi didn't want any part of that. He decided to leave his position as the keeper of archives at the Zhou Court and disappear from the public sphere.

Knowing of Laozi's great wisdom, Yinxi pleaded for Laozi to stay. His teachings could help keep society in line. Laozi remained determined to live a life in seclusion but heeded Yinxi's request. In a few days, he wrote the Tao Te Ching and handed it to Yinxi, leaving his knowledge and wisdom behind. Then, Laozi faded away into obscurity.

Laozi's lessons are prescriptive and metaphysical, stressing the importance of balance with the universe. The core tenets of his writing - simplicity, non-action (Wu Wei), humility, balance, and spontaneity - are best applied to one's daily life. At first, I didn't think they fit the predicament I was in. I tried keeping things simple, and my house was piling up with unfinished business. Non-action was precisely my problem. Sure, I practiced humility, but my life wasn't in balance, and there was too much spontaneity.

I nearly put the book down, ready to jump headfirst into a more militaristic and disciplinary regimen of life. Thankfully, I didn't. I kept reading.

Finding The Way

Simplicity

The Tao Te Ching teaches simplicity by espousing a life that is natural, unadorned, and in harmony with the universe. In practical terms, this means living in a minimalist setting - don't get too attached to physical items. Purchase things for their utility and get rid of them when there is no utility left.

I came to notice that my children had way too many toys. I had way too much clothing and trinkets. My wife was saving and storing, or hoarding (depending on the day), a garage full of things. In short, we had too much stuff. It's great when you can afford to make the people in your life happy, and there's no greater feeling than gifting things to our loved ones, but eventually, the stuff piles up. If there's not a steady stream of items going out as there is coming in, you end up with clutter.

I quickly noticed it was the toys my children didn't care for that were left strewn across the floor. It was the clothes that didn't fit me or were so old they were left hanging out in the back of the closet that collected dust and drained my motivation to put clothes away after washing.

It's important to take care of what you have. It's impossible to take care of everything you have unless you de-clutter.

Wu-Wei: Non-Action

Contrary to what it may seem, this doesn't mean being lazy.

Rather, Wu-Wei means to go with the flow of life. After having to ask my mother for a loan, I was prepared to go full-on military mode with hard schedules for when to do the lawn, clean the house, and do the dishes. This intense discipline, the strict adherence to a schedule, is unnatural. You may very well be able to keep up with a strict schedule for a while, but eventually, it'll burn you out. I know people who always stick to a schedule and are super successful. However, I also noticed that they would regularly need "breaks" from their life. You can take all the vacations you want, but you can never take a break from life - life just is.

That's the crux of Wu-Wei: live your life in a sustainable way.

Now, I spread out the activities that need to happen around the house. Rather than waiting for a scheduled point in time, I try to clean up after myself as I go. When things pile up, I find the opportune moment to do things right, but I don't stress about it.

Humility

Part of humility is recognizing that I am no different than any other human in existence. There are no special rules that apply to me, and no one else will take care of my things.

This helped me decouple the feeling of embarrassment whenever I'd visit a friend's impeccably well-kept house. It removed the act of keeping my house tidy as a status symbol. It converted the act of tidying into an act self-care and self-respect.

Don't Add To The Stress of Life

The teachings of the Tao Te Ching have transformed my approach to daily life, making it less stressful and more fulfilling. By embracing simplicity, I've learned to cherish what truly matters and let go of unnecessary clutter. Wu Wei has taught me the value of living in harmony with the natural flow of life, reducing the burden of rigid schedules. Humility has reminded me of the shared human experience and the importance of taking responsibility for my environment without comparison.

Implementing these principles has not only improved the physical state of my home but also brought a sense of peace and balance to my life. The Tao Te Ching's wisdom has guided me toward a more mindful and sustainable way of living, where the little things are taken care of, and the chaos is managed with grace. In the end, it's not about perfection but about finding harmony and contentment in the everyday moments, leading to a life that feels less like a series of tasks and more like a journey of continuous growth and self-discovery.

Kombucha tea has been enjoyed for generations and passed down from family to family. The tea-mushroom has a high vitality and a great capacity for regeneration, which is why it has survived for over 2000 years.

Did you know that these remarkable organisms have a built-in defence mechanism that protects them from impurities? The Kombucha mushroom boasts several protective features, including organic acids, low alcoholic content, carbonic acid, and antibiotic products. These elements work together to prevent the growth of foreign microorganisms, ensuring that the mushroom remains healthy and thrives.

Russian researcher I.N. Konovalow, in his 1959 report, noted that the rapid growth of the tea-mushroom leaven and bacteria significantly suppresses the spread of other yeast and bacterial varieties. Similarly, Professor G.F. Barbancik, in his book on the tea-mushroom, reported that the tea-mushroom bacteria actively drive out other microbes, a phenomenon known as antagonism.

The Kombucha mushroom is not only robust, but it's also easy to cultivate and share with others. It grows rapidly and is happy to be partitioned, making it an excellent choice for sharing with friends. In fact, passing on the Kombucha mushroom to others is a thoughtful gesture of friendship and mutual helpfulness. If you would like to brew your own kombucha, we are more than happy to set you up with some SCOBY and advice to get you started.

At the core of human discord lies an elusive yet pervasive force: selfishness. This trait, embedded in every individual, obstructs humanity's progression and projects itself into our collective consciousness. Cultivated unconsciously throughout evolution, selfishness continually seeks more resources, contributing to global disintegration. Humanity, driven by its weaknesses and desires, unwittingly sustains this self-centered impulse, often ignoring the true source of unity: a higher, all-encompassing power.

To transcend selfishness and elevate global consciousness, humanity must recognize and align with the unifying essence inherent in all existence. This recognition arises from a profound understanding of the higher power, guiding us to instill values that transcend self-interest. By promoting spiritual education, ethical values, and altruistic behavior, we can catalyze this transformative shift.

A critical step is acknowledging the presence of a common unifying force across all dimensions of human experience. It is essential to reassess every aspect of how human consciousness engages with the world, from subtle spiritual realms to social and educational systems. Aligning individual and collective actions with the principles of this higher power is crucial for nurturing an environment that eradicates selfishness and fosters spiritual growth.

This ambitious endeavor requires collaborative community efforts, highlighting the importance of collective contributions towards building an enlightened and interconnected world. Together, we can leave a lasting impact on the global landscape, cultivating values rooted in the recognition of a unifying higher power and fostering harmonious coexistence beyond individual concerns.

給予自由的肯定

這是一個肯定的日子，一個慶祝自由的日子。我們以自由的名義站在這裡。我們致力於和平與非暴力的變革。

我們必須承認我們所有人民的完全平等。不僅僅是針對特定宗教的人。不僅僅是針對特定種族的人。

不只是有錢人。但對所有的人來說。我們這樣做必須有一個單一且根本的理由。

這是正確的做法。今天早上，這個國家最著名的政治王朝出現了新的轉折。小羅伯特‧甘迺迪。

一位民主黨人試圖治癒分裂的國家並將權力歸還給人民。小羅伯特·F·甘迺迪：今天我們被告知，我們的國家已經陷入無可救藥的分裂。但當我在這個國家旅行時，我發現了一些不同的東西。

比特幣

我目睹了前所未有的樂觀情緒。我們內心深處有某種東西在激動，告訴我們事情不必是這樣的。所以我今天來到這裡是為了宣布我們擺脫腐敗的暴政。

這剝奪了我們負擔得起的生活、我們對未來的信念以及我們對彼此的尊重。但要做到這一點，我必須先宣布自己的獨立性。獨立於民主黨。

以及所有其他政黨。我並不是輕易做出這個決定的。放棄我的叔叔、我的父親、我的祖父以及我的兩位曾祖父的聚會對我來說是非常痛苦的。

但與 247 年前我們的開國元勳簽署《獨立宣言》時所冒的風險相比，我的犧牲根本算不了什麼。他們知道，如果他們的革命失敗，他們所有人都會被絞死。他們選擇賭上一切。

當約翰·亞當斯放下筆，在宣言上簽名後，他轉向在場的人，對他們說，沉或遊，生或死，生存或滅亡。從今天起，我就和我的祖國在一起了。今天我將向你們做出同樣的承諾。

這樣我就可以站在你們面前，就像每個領導人都應該站在你們面前一樣。沒有黨派忠誠。不受幕後交易的影響。

只為我的良心、我的創造者和你服務。每一位總統上任時都承諾要團結全國，並與兩黨人士合作。他們中沒有人這樣做過。

他們不能。他們已經選好了一方。好吧，我不會遇到這個問題。

我將在兩黨之間建立聯盟。除了極少數實際上腐敗的公職人員之外，我要告訴你這個秘密。他們也希望從束縛他們的體制中解放出來。

這不就是我們所有人最終想要的嗎？從一個剝奪我們財富、健康、希望、愛國主義、理想、自由以及最終剝奪我們作為一個善良和有能力的人民的意識的體系中解放出來。治癒我們分裂的國家有可能嗎？我們去奪回我們的國家吧。上帝祝福你。

上帝保佑美利堅合眾國。我是一個真正的美國人。為正義而戰。

為你的生命而戰。女士們、先生們，請歡迎美國下一任總統小羅伯特‧甘迺迪先生。為每個男人而戰。

我是一個真正的美國人。你好，比特幣愛好者。我很高興能回來參加我的第二次比特幣會議。

自從去年在邁阿密以來，我一直在與這個社群的領導人和思想家會面。我與比特幣礦工、政策制定者、經濟學家、金融專家、投資者、開發人員和企業家進行了交流，以加深我對比特幣為我們國家和地球帶來的非凡前景的理解。據我所知，身為美國總統，我打算在第一天簽署一項行政命令，指示司法部和美國法警將美國政府持有的約 20 萬個比特幣轉移到美國財政部，它將作為戰略資產持有。

在就任總統的第一天，我將簽署另一項行政命令，指示美國財政部每天購買550 個比特幣，直到美國建立起至少400 萬個比特幣的儲備以及任何其他國家都無法篡奪的主導地位。我們國家擁有全球約 19% 的黃金儲備。這項政策將為我們提供大約相同比例的比特幣總量。

這些行動的連鎖影響最終將使比特幣的估值達到數百萬億美元。在擔任總統的第一天，我還將簽署一項行政命令，指示美國國稅局發佈公共指導方針，規定比特幣和美元之間的所有交易都是不需報告的交易，並且不需納稅。在就任總統的第一天，我還將簽署一項行政命令，指示美國國稅局將比特幣視為符合 1031 法案兌換成房地產的資產。

現在，我想談談我對比特幣社群的觀察，我認為自己是比特幣社群的一部分。儘管他們的觀點不同，但我發現比特幣社群最顯著的特徵是這種矛盾的並置，其特點是在幾個小問題上的激烈分歧和在更大的比特幣生態系統中壓倒性的團結感。比特幣社群讓我想起了美國政治應該是什麼樣子。

我們的願望、對國家的信念以及美國值得為之奮鬥的信念最終是一致的。最終，我們大家再次團結在一起，堅信比特幣是一種促進自由、樂觀、獨立、民主和透明的技術。它是希望的貨幣。

它是完美的貨幣。它是一個優雅、詩意、美麗、純粹的物種，與美國自治實驗所代表的最高理想和願望完美契合。它是廉潔的。

它具有完整性。它有自主主權。它促進個人責任和問責制。

它是去中心化和民主的。它對政府影響很小，對個人自由影響很大。比特幣是反戰的。

它是政府腐敗的兇猛、無情、不可戰勝的敵人。現在，你們中的許多人都知道我自己對比特幣的介紹，我自己的轉換。我從孩子們那裡知道了比特幣，但對我來說，它幾乎像是一種時尚或新奇事物。

交易自由和自我主權的重要性

然後我看到了渥太華發生的事情。當時我正在管理兒童健康保衛組織，它是我國醫療自由的首要倡導者。我們在加拿大罷工的卡車司機中安插了一名記者，為我們的通訊服務。

她和卡車司機一起從艾伯塔省一路開往渥太華。加拿大的卡車司機非常多元化。他們是亞洲人，他們是黑人，他們是白人。

卡車司機正在做我們國家所有人都認為理所當然的事情。他們正在政府中就他們認為重要的事情提出請願書，即這些命令對其業務的財務影響。如果你看一下那個活動的視頻，你會發現它就像伍德斯托克音樂節一樣。

人們分送水瓶，撿拾垃圾，播放音樂，彼此友善。但它被加拿大政府描述為右翼、極端主義、暴力恐怖組織。政府開始使用臉部辨識系統和其他形式的監控來了解卡車司機的身份，查看他們的車牌等。

然後凍結了他們的銀行帳戶。他們還凍結了價值 1200 萬美元的 PayPal 帳戶。當加拿大做到這一點時，我立即想到，交易自由與第一修正案中的言論自由一樣重要。

因為如果政府有能力，這些卡車司機就不會被指控犯罪，更不用說被定罪了。然而政府卻能夠關閉他們的銀行帳戶。他們無力支付抵押貸款。

他們無法為卡車購買柴油。他們無法為孩子們購買食物。一名卡車司機告訴我，他將因無法支付強制性贍養費而入獄。

如果一個政府能夠讓你挨餓，把你趕出家門，如果你公開反對它，如果你批評政府政策，那麼我們就走上了極權主義和奴隸制的道路。從那時起我就開始認真尋找替代方案。正是那次事件讓我立即意識到這項技術在提供交易自由和自我主權方面的潛力。

去年在這次會議上，我提議，作為你們的總統，我將努力確保比特幣的自我託管權、在我們自己家裡運行節點的權利、阻止聯邦政府篡奪第一修正案的開源隱私權——增強技術。我承諾阻止政府官員採用 CBDC，這將不可避免地演變成我們在加拿大看到的那樣，一種用於監視和控制的惡意工具。最重要的是，我承諾確保美國作為全球加密貨幣創新、創業、投資和科技中心的地位。

作為一個終身的環保主義者，我接受比特幣作為一種激勵對綠色和再生能源生產進行更多投資的機制。去年與比特幣愛好者一起度過之後，我離開邁阿密會議時，對比特幣及其消除國家債務作為對沖通膨的潛力的樂觀和興奮所著迷。它承諾保障個人自由，恢復美國中產階級，結束政府腐敗，減少戰爭機器的資金，並保護我們的環境。

就在那之前，在邁阿密大會上，我從贏得孟山都案的費用中得到了一張大支票。我拿走了大部分支票，它代表了我個人財富的最大部分，並將其全部投資於比特幣。我這樣做並不是希望能夠快速獲得投資回報。

有人告訴我，你可能要等很久。你可能會有很多焦慮和心絞痛。所以我為此做好了準備。

但順便說一句，如果這是我唯一的動機，我不會失望。我加入得恰逢其時。在過去的一年裡，我在兔子洞裡走得更遠了。

讓我來說說，橘色兔子洞。我現在比以往任何時候都更加相信，我們必須共同努力，立即將所有這些建議付諸實施。美國正處於十字路口。

我們可以繼續走現在的道路，增加債務，限制自由，沉迷於戰爭，或者我們可以期待使用比特幣等新技術來幫助我們發展，再次實現我們作為道德權威和世界的承諾。現在，我很高興得知我並不是唯一在今年選舉中談論比特幣的人。沒有什麼比看到其他政治領袖加入比特幣潮流更讓我高興的了。

比特幣對政治領袖的潛力

我花了一年多的時間來研究、理解、闡明比特幣的潛力。作為第一位比特幣總統，我的目標是製定政策，使美國成為世界上最偉大的比特幣代表及其民主價值的支持者。我從小就認為美國將永遠保持其世界領袖、自由世界領袖的地位。

但自 1993 年蘇聯解體以來，我們一直在螺旋式下降中遠離這個角色。傲慢、軍事冒險主義和腐敗使美國的政治和經濟實力急劇下降。我們的美元正在迅速失去儲備貨幣地位，因為我們已將其武器化以對抗其他國家。

當我們不同意另一個國家的政策時，我們會將其從 SWIFT 系統中剔除，並取消其銀行帳戶。作為該策略的可預見結果，金磚國家目前正處於透過擺脫石油美元來實現去美元化的過程中。他們意識到，用商品和其他硬資源換取憑空印製的貨幣是一種失敗的做法。

這種趨勢可能會加速，直到我們再次艱難地過渡到用硬資產支持我們的債務。我有一個計劃，透過用硬資產（包括貴金屬和比特幣的組合）來支持美國國庫券、票據和債券，來強化美元、降低利率並抵消我們 34 兆美元的債務。透過用硬資產抵押來支持美國債務不僅可以恢復美元的實力，控制通貨膨脹，還將開創美國金融穩定、繁榮與和平的新時代。

世界需要相信，我們已經安全地束縛了我們的政府及其在沒有工作證明的情況下憑空創造貨幣的能力。我提出的創新策略利用了比特幣以及黃金和其他硬資產的稀缺性和流動性，以恢復美元在全球金融中的主導地位。世界將爭相採用一種由美國支持的去中心化貨幣，這種貨幣不能被政府沒收，可以在手機上以光速跨越全球邊界進行交易和交易，而無需銀行費用或其他交易摩擦。

這種廉潔的貨幣將立即開始將全球其他國家的財富和資產拉回美國，恢復我們美元的實力並修復我們的國際收支平衡。在他被暗殺前六個月，我的叔叔約翰·F·甘迺迪總統簽署了一項行政命令，將銀幣與聯準會發行的紙幣競爭。他的目的是控制聯準會的自由裁量權。

他一直批評聯準會的政策，希望結束酌情貨幣政策和不可避免的美元貶值。他明白，高槓桿經濟直接導致破壞性的財富不平等，這種不平等如今正在侵蝕美國民主，引發暴力、分裂、不滿和絕望。值得注意的是，在我叔叔被暗殺後，政府立即停止發行這些銀幣，權力又回到了聯準會。

我叔叔顯然明白聯準會有可能演變成暴政。比特幣有可能讓聯準會恢復貨幣紀律，並恢復美元作為無可爭議的全球儲備貨幣的地位。正如比特幣可以強化美元一樣，它也可以確保美國在網路空間的地位。

建立比特幣的諾克斯堡

據我了解，明天川普總統可能會宣佈建造比特幣諾克斯堡的計劃，並授權美國政府購買100萬比特幣作為戰略儲備資產。我對這項宣布表示讚賞，我們都應該為它鼓掌。我希望川普總統對比特幣的承諾不僅僅是政治上的權宜之計。

支持比特幣最憤世嫉俗的政治原因是透過政策讓美國6,000萬比特幣持有者興奮不已，讓持有者數量增加。但我希望川普總統和民主黨全國委員會提名人，無論他或她是誰，能夠更深入地了解確保比特幣在美國財政部擁有戰略儲備的驚天動地的原因。其中最引人注目的原因在美國太空部隊少校賈森·洛厄裡 (Jason Lowery) 的麻省理工論文《軟體》中列出。

洛厄裡少校指出，比特幣被錯誤地描述為貨幣，而實際上它是一種網路防禦系統，可以保護我們在網路空間中的線上身分和資料。正如我們有空軍來保護我們的天空，有海軍來保護我們的海洋一樣，比特幣可以保護我們免受潛在的網路攻擊。它是一種網路防禦武器，也是未經認可的使用的典型例子。

這是一個類似的例子。中國人發明了火藥，並將其作為藥物使用了 200 年，之後其他國家才認識到它是最強大的力量投射工具。如今，人們普遍認為比特幣的用途是貨幣。

但比特幣也是一種力量投射武器，可以保護我們的貨幣和我們在網路上所做的一切免受網路攻擊。第一個承認這項功能的國家將成為新的全球超級大國。如果我們想重新獲得並鞏固我們作為自由世界領導者的頭銜，我們需要抓住控制權並充分利用比特幣的潛力。

根據公開訊息，美國目前擁有20.4萬枚比特幣，是全球第五大比特幣錢包。將比特幣添加到該儲備中將有助於確保美國未來 250 年的未來。我在甘迺迪政府中的首批員工之一是洛瑞少校，他將擔任我的國家安全團隊的高級顧問。

比特幣對美國和世界的另一個重要用途是我最珍惜的，即透過比特幣挖礦捕獲碳並激勵綠色能源生產。我擔任環保倡議者服務了 40 年，並在綠色科技創投公司 Vantage Point 擔任合夥人 10 年，該公司是世界排名第一的綠色科技能源和技術公司。我在開發一些世界上最大的太陽能和風力發電專案中發揮了關鍵作用。

由於比特幣的高能源需求，比特幣的批評者錯誤地將其視為環境威脅。當然，事實恰恰相反。比特幣礦工對能源定價比其他任何行業都更加敏感。

這意味著他們只能利用最便宜的能源才能在市場上生存，這必然意味著浪費能源和剩餘電力。例如，垃圾掩埋場產生的甲烷本來會進入大氣中，但比特幣礦工擁有獨特的能力，能夠利用它作為能源。比特幣挖礦也是再生能源和風能和太陽能等可變電力專案的理想合作夥伴。

我在能源專案融資方面的個人經驗讓我深深認識到比特幣挖礦作為再生能源專案可靠的利潤中心的關鍵潛力，這些專案需要靈活的現場非高峰客戶來間歇性發電以獲得融資。比特幣礦工是此類專案的理想合作夥伴。好吧，讓我們來看看比特幣對美國人和美國有利的其他一些方面。

美國人購買力的削弱

1971 年，尼克森總統取消了金本位制，以資助越戰。從那時起，美元的購買力急劇下降，侵蝕了普通美國人的儲蓄和收入。擔任聯準會主席20年的艾倫‧格林斯潘甚至警告說，在沒有金本位的情況下，沒有辦法防止儲蓄因通貨膨脹而被沒收。結束報價。

眾所周知，通貨膨脹就是竊盜。而且幾乎總是從窮人那裡偷竊。聯準會設計了一台超高效的印鈔機來進行系統性的搶劫，摧毀了美國中產階級並大量消滅了美國的工薪階級。

淫穢的印鈔以隱性的通貨膨脹稅耗盡了我們公民的購買力。正是川普和拜登政府不計後果地擁抱印鈔，才將中產階級推向了臨界點。美國家庭現在在這場大雨中不堪負荷。

我們簡單來看一下。如果六年前您有 1,000 美元，那麼就購買商品和服務的能力而言，這 1,000 美元今天的價值為 520 美元。抵押貸款四年內翻了一番。

難怪 18 至 30 歲的年輕人中有一半仍然住在家裡，買不起邁向美國夢第一步的房子。難怪我們年輕的美國人結婚較晚，推遲甚至放棄建立家庭的選擇。他們購買力的下降迫使他們做出這些犧牲。

我們都認為儲蓄穩定成長是我們生活的一部分，但它卻推動了儲蓄穩定成長這項任務的絕望。今天，這一代人正面臨這些移動的球門柱。他們賺錢了，他們認為自己做得很好，然後錢就消失了。

並不是因為他們做了什麼，而是因為通貨膨脹。它把這一代人推向了一種金融虛無主義，助長了抑鬱、自殺、絕望、異化、剝奪、對我們國家的自豪感的喪失、對他們自己的生活失去希望的流行。一代人和自己的未來。醫療保健費用也在指數級增長。

幾個月前，我和新罕布夏州的一對年輕夫婦交談過，他們含著淚水告訴我，他們是如何吵架的，一對丈夫和妻子，晚上懷裡抱著一個哭鬧的嬰兒，不得不想知道他們是如何爭吵的。超過一半的美國人在遇到緊急情況時拿不出 1,000 美元。如果你是這群人中的一員，而你的車裡的引擎燈亮了，那就是世界末日，因為你知道你將負擔不起機械師的費用。

你將無法上班。你將無法支付房租，然後你就會流落到人行道上。那個卑鄙的人最終來到了這支軍隊，在我居住的城市裡的帳篷營地，在洛杉磯、紐約、舊金山，在全國各地，美國人的軍隊，勤奮的美國人，現在生活在那裡，因為引擎他們的車燈亮了，或者他們同時有兩個輪胎癟了，或者他們有一些其他未預料到的費用。

走到外面，你就會看到它。我一次又一次地聽到美國老年人講述他們如何減少處方，將處方藥減成兩半，以使其持續到週末。他們在汽油、家用暖氣油和食品之間做出選擇。

很多媽媽告訴我，她們正在降低原料的等級，以擺脫雜貨店收銀台的排隊等候。今天的美國人被迫做出這些痛苦的決定，因為我們的錢已經花光了。對於陷入困境的美國中產階級來說，對於陷入困境的美國中產階級來說，比特幣是通貨膨脹厄運高速公路的出口匝道。

削減軍事工業複合體的資金

如果世界採用比特幣標準，而我們的貨幣保值，我們就有能力過更豐富的生活。比特幣支持者是對的。解決金錢問題，解決世界問題。

將我們的美元與比特幣等硬資產掛鉤的紀律也將最終打破我們對永遠戰爭的沉迷。法定貨幣的發明是為了資助戰爭。正如我剛才指出的，尼克森總統在 1971 年讓我們擺脫了金本位制，因為印刷法定貨幣是為越戰持續提供資金的唯一途徑。

厭倦了法定貨幣，當一個國家的錢用完時，戰爭就會結束。或者，如果一個政府想要資助一場戰爭，它會發行戰爭債券並向其公民借錢，或者會提前告訴他們，我們要向你們徵稅。如今，政府甚至不需要請求許可。

他們只是在印鈔票。然後他們用假錢資助戰爭。如果世界採用比特幣標準，那麼就不會有戰爭，因為政府無法印製比特幣。

我是比特幣的支持者，因為它可以為軍事工業複合體提供資金，而軍事工業複合體不是致力於國防，而是致力於國際全球統治。我就這麼說吧。冷戰高峰期，軍事預算以 2024 年美元計算約 5,000 億美元。

今天，它是這個數字的兩倍。為什麼我們需要的資金是冷戰高峰的兩倍？我們需要它，因為它與國防無關。它與全球霸權和國際統治有關，但實際上適得其反。

它讓我們在國內破產。它破壞了我們在全球範圍內的關係和道德權威。我再說一次。

如果政府無法透過在電腦上敲擊幾下鍵盤來印鈔票，他們就無法為永無止境的戰爭提供資金。再說一遍，修復金錢，修復世界。不犯錯。

我的政府修復我們破損資金的主要原因之一是取消對戰爭機器的資助。為了實現這一目標，我將支持對比特幣的直接所有權實施免稅。將比特幣兌換回美元將是一項無需向美國國稅局報告的交易，並且不受資本利得的影響。

比特幣與個人自由的鬥爭

我們必須記住，第四修正案保障隱私權。身為一名立憲主義者，我堅決捍衛我們的財務和交易隱私權。當美國公民被要求向國稅局報告每筆比特幣交易時，政府知道我們用錢所做的一切。

政府無權了解你的業務。更重要的是，對比特幣的直接所有權實施免稅，會產生購買比特幣而不是比特幣 ETF 的經濟激勵，因為比特幣 ETF 是一種證券，因此會產生資本利得。這一點至關重要，因為直接擁有比特幣可以使其去中心化。

這是防止貝萊德和其他全球資產管理公司對比特幣網路、分叉和升級產生不當影響的唯一方法。 2014年，美國國稅局宣布比特幣為財產，並將其買賣視為資本交易進行監管。重要的是要了解這項稅法從未由國會通過，也從未由美國總統簽署成為法律。

美國國稅局和美國證券交易委員會只是篡奪了政府權力，以壓制去中心化的金融民主。美國最高法院最近根據「雪佛龍主義」重新審理了這項決定。這項決定讓爭取自由的比特幣支持者能夠挑戰 2024 年對比特幣徵稅的合憲性。

我今天告訴你們，我永遠不會簽署一項對比特幣直接所有權徵稅的法律。我將利用我的權力推翻任何這樣做的法律。我將結束拜登政府對比特幣的戰爭。

免稅的比特幣不僅對公民的財務自主權、自由和隱私至關重要，而且對於保持中本聰創造的去中心化和民主也至關重要。最後，比特幣保證財產權。有了可自由交易的比特幣，任何政府都無法在邊境沒收或徵稅您的財富。

這是比特幣作為反對極權主義武器的效力的另一個例子。因此，隨著這個選舉週期開始升溫，你必須做出選擇。你已經聽到我打算做什麼了。

讓我們將其與我的共和黨對手的提議進行比較。我歡迎川普總統對比特幣的新熱情，但他剛開始比特幣對話幾週，而我的優勢是可以在這裡停留更長時間。希望他的學習曲線能反映我所經歷的那種。

我的猜測是，至少在最初，將會有許多關於定價以及政府政策的變化如何讓比特幣持有者變得富有的討論。但我們都知道，這只是比特幣的一小部分。比特幣的意義更大。

比特幣關乎我們的靈魂。這是關於我們的價值觀。價格上漲特徵是其所有屬性中最不重要的。

川普總統還有很長的路要走，才能解釋他的個人價值觀如何與比特幣支持者的價值觀保持一致。如果他不這樣做，那麼我們就無法真正保證他的認可不會是另一種短暫的貨幣政策風尚。這項保證將要求他否認上屆政府的一些核心政策。

在白宮任職期間，川普總統一直公開反對比特幣。 2020 年 12 月，他公開敵視比特幣，並試圖取締自助錢包。在這個時期，美國人比歷史上任何時候都更需要任何價值儲存手段，以補償他們因封鎖、購買力下降、印鈔狂歡和新冠疫情而導致的收入。

2021 年，川普總統加倍努力，宣稱比特幣看起來只是個騙局。我不喜歡它，因為它是另一種與美元競爭的貨幣。我很高興川普總統發生了這種演變。

我很自豪我幫助開闢了一條道路，使其他政治領導人更容易效仿。我感謝 50 或 6000 萬比特幣支持者，例如 Michael Saylor，他們在我之前幫助我了解了比特幣拯救國家的潛力。我認識的每一位比特幣愛好者都和我一樣渴望自由，或者對官方正統觀念和聲明持懷疑態度，以及我最欣賞的批判性思維傾向。

在新冠疫情期間，川普總統和拜登總統都沒有保護我們的憲法權利。他們都限制我們集會、禮拜的權利。他們關閉了我們的教堂，沒有祖母的葬禮，沒有婚禮。

他們未經正當程序或僅給予補償就關閉了我們的業務，違反了第五修正案。他們終止了第七修正案的陪審團審判權。他們攻擊了第四修正案禁止無證搜索和扣押的禁令。

而這兩屆政府也允許聯邦調查局和間諜機構與社群媒體公司合作，壓制批評政府政策的人，從而壓制我們的言論自由權。我希望川普總統對比特幣的態度改變證明了對個人自由、我們的憲法和我們的權利法案的新的、根深蒂固的承諾。如果川普總統當選，他會為比特幣而戰嗎？我希望他上週在共和黨全國委員會的演講中提到了比特幣。

我很失望。上週他花了很多時間攻擊薩爾瓦多總統布克萊，薩爾瓦多是唯一採用比特幣標準的國家。布克萊總統是薩爾瓦多史上最受歡迎的總統。

在比特幣的幫助下，他扭轉了國家的局面。比特幣幫助他發展了經濟並減少了犯罪。美國應該效法布克萊總統的做法，學習他在比特幣方面給我們的一些教訓。

更令人擔憂的是，川普總統上個月在接受彭博社採訪時提出了任命傑米·戴蒙擔任財政部長的想法。我很感激川普總統昨天收回了這一言論，但我不確定他怎麼會考慮招惹比特幣長期最大的批評者之一。也是世界上集中控制的最終倡導者。

如果他真正在靈魂中致力於我們所有人都致力於的自由和去中心化，那麼這些選擇就不符合比特幣的精神定位。比特幣代表......我的意思是，就我個人而言，我寧願看到像邁克爾·塞勒或凱特琳·朗這樣的人擔任財政部長。他們很聰明。

它們是百科全書式的。他們具有前瞻性。他們深深地熱愛我們的國家。

它們代表了權力下放和經濟民主的理想。最後，川普總統有四年的時間來赦免羅斯·烏布里奇、朱利安·阿桑奇和愛德華·斯諾登。但他沒有這麼做。

我們需要問自己為什麼。我已經調查了這些案件，並計劃在第一天就將他們全部赦免。在這個選舉年，我鼓勵你研究你的選擇，看看候選人的政策，但更重要的是，看看他們的行動，以確定他們是否真正是問題的一部分，或者是否是解決方案的一部分。

確定它們是否符合您內心的信念。記住美國人的需要，記住美國人需要什麼，我們想要什麼，然後相應地投票。今天我想向大家傳達對比特幣、對比特幣社群的核心信念。

比特幣是自由的貨幣、自由的貨幣、希望的貨幣。它將自我主權恢復給個人，這就是美國民主的全部目的。它為我們提供了數位產權，這是我們民主的核心，它提供了一種價值儲存手段，使美國中產階級能夠再次過著富裕的生活。

我想成為能夠帶回希望的總統，我很高興成為你們比特幣社群的一員事實上，我不認為自己是紅色的，我不認為自己是藍色的，我也不認為自己是紅色的，我不認為自己是藍色的，我也不認為自己是紅色的。這些都是政黨的顏色。相反，我認為自己是橙色的。

那就是，那是自由的顏色。川普總統確實有橙色的頭髮。我只能遠遠地欣賞他。

我永遠無法告訴你這是一個非常好的開始，但我有一顆橙色的心，這就是你應該支持的。非常感謝大家，願上帝保佑你們。比特幣會議。

Censorship-resistant relay discovery in Nostr

In Nostr is not decentralized nor censorship-resistant I said Nostr is centralized. Peter Todd thinks it is centralized by design, but I disagree.

Nostr wasn't designed to be centralized. The idea was always that clients would follow people in the relays they decided to publish to, even if it was a single-user relay hosted in an island in the middle of the Pacific ocean.

But the Nostr explanations never had any guidance about how to do this, and the protocol itself never had any enforcement mechanisms for any of this (because it would be impossible).

My original idea was that clients would use some undefined combination of relay hints in reply tags and the (now defunct) kind:2 relay-recommendation events plus some form of manual action ("it looks like Bob is publishing on relay X, do you want to follow him there?") to accomplish this. With the expectation that we would have a better idea of how to properly implement all this with more experience, Branle, my first working client didn't have any of that implemented, instead it used a stupid static list of relays with read/write toggle -- although it did publish relay hints and kept track of those internally and supported kind:2 events, these things were not really useful.

Gossip was the first client to implement a truly censorship-resistant relay discovery mechanism that used NIP-05 hints (originally proposed by Mike Dilger) relay hints and kind:3 relay lists, and then with the simple insight of NIP-65 that got much better. After seeing it in more concrete terms, it became simpler to reason about it and the approach got popularized as the "gossip model", then implemented in clients like Coracle and Snort.

Today when people mention the "gossip model" (or "outbox model") they simply think about NIP-65 though. Which I think is ok, but too restrictive. I still think there is a place for the NIP-05 hints, nprofile and nevent relay hints and specially relay hints in event tags. All these mechanisms are used together in ZBD Social, for example, but I believe also in the clients listed above.

I don't think we should stop here, though. I think there are other ways, perhaps drastically different ways, to approach content propagation and relay discovery. I think manual action by users is underrated and could go a long way if presented in a nice UX (not conceived by people that think users are dumb animals), and who knows what. Reliance on third-parties, hardcoded values, social graph, and specially a mix of multiple approaches, is what Nostr needs to be censorship-resistant and what I hope to see in the future.

Nostr: a quick introduction, attempt #1

Nostr doesn't have a material existence, it is not a website or an app. Nostr is just a description what kind of messages each computer can send to the others and vice-versa. It's a very simple thing, but the fact that such description exists allows different apps to connect to different servers automatically, without people having to talk behind the scenes or sign contracts or anything like that.

When you use a Nostr client that is what happens, your client will connect to a bunch of servers, called relays, and all these relays will speak the same "language" so your client will be able to publish notes to them all and also download notes from other people.

That's basically what Nostr is: this communication layer between the client you run on your phone or desktop computer and the relay that someone else is running on some server somewhere. There is no central authority dictating who can connect to whom or even anyone who knows for sure where each note is stored.

If you think about it, Nostr is very much like the internet itself: there are millions of websites out there, and basically anyone can run a new one, and there are websites that allow you to store and publish your stuff on them.

The added benefit of Nostr is that this unified "language" that all Nostr clients speak allow them to switch very easily and cleanly between relays. So if one relay decides to ban someone that person can switch to publishing to others relays and their audience will quickly follow them there. Likewise, it becomes much easier for relays to impose any restrictions they want on their users: no relay has to uphold a moral ground of "absolute free speech": each relay can decide to delete notes or ban users for no reason, or even only store notes from a preselected set of people and no one will be entitled to complain about that.

There are some bad things about this design: on Nostr there are no guarantees that relays will have the notes you want to read or that they will store the notes you're sending to them. We can't just assume all relays will have everything — much to the contrary, as Nostr grows more relays will exist and people will tend to publishing to a small set of all the relays, so depending on the decisions each client takes when publishing and when fetching notes, users may see a different set of replies to a note, for example, and be confused.

Another problem with the idea of publishing to multiple servers is that they may be run by all sorts of malicious people that may edit your notes. Since no one wants to see garbage published under their name, Nostr fixes that by requiring notes to have a cryptographic signature. This signature is attached to the note and verified by everybody at all times, which ensures the notes weren't tampered (if any part of the note is changed even by a single character that would cause the signature to become invalid and then the note would be dropped). The fix is perfect, except for the fact that it introduces the requirement that each user must now hold this 63-character code that starts with "nsec1", which they must not reveal to anyone. Although annoying, this requirement brings another benefit: that users can automatically have the same identity in many different contexts and even use their Nostr identity to login to non-Nostr websites easily without having to rely on any third-party.

To conclude: Nostr is like the internet (or the internet of some decades ago): a little chaotic, but very open. It is better than the internet because it is structured and actions can be automated, but, like in the internet itself, nothing is guaranteed to work at all times and users many have to do some manual work from time to time to fix things. Plus, there is the cryptographic key stuff, which is painful, but cool.

In the annals of digital currency history, the journey from Wei Dai's groundbreaking "B-Money" to Satoshi Nakamoto's revolutionary Bitcoin is a tale of innovation, vision, and evolution. 🌟

📜 The Genesis of B-Money

Wei Dai, a pioneering figure in the digital currency space, introduced the concept of "B-Money" in 1998. His seminal paper, B-Money, outlined the foundational principles of what would later evolve into the modern digital currency landscape. 🧠💡

In his proposal, Dai explored several concepts that would become cornerstones of cryptocurrency technology:

• Crypto-Anarchy: A vision for a system free from centralized control, relying on cryptographic principles to ensure privacy and security.
• Community and Anonymity: The idea of a decentralized community where identities are hidden and transactions are private.
• Hidden Location and Protocols: Creating a system with decentralized nodes, each maintaining a distributed database.
• Incentives and Digital Pseudonyms: The use of public keys and message signatures to establish identity and secure transactions.
• Broadcast and Encryption: Techniques for secure communication and transaction verification.
• Currency Units and Computational Cost: Linking currency creation to computational effort, introducing the concept of mining.

🔍 From Vision to Reality: The Bitcoin Revolution

Fast forward to 2008, when an anonymous entity known as Satoshi Nakamoto unveiled Bitcoin to the world. Inspired by Dai's "B-Money," Satoshi Nakamoto brought these concepts to life with Bitcoin, addressing the challenges and harnessing the potential of digital currency. 📅💥

Bitcoin took these early ideas and turned them into a working reality with several key innovations:

• Decentralization: Unlike traditional currencies, Bitcoin operates on a decentralized network of nodes, removing the need for a central authority.
• Blockchain Technology: Bitcoin introduced the blockchain—a distributed ledger that records all transactions securely and transparently.
• Proof of Work: The concept of mining was refined, with computational work required to validate transactions and secure the network.
• Incentive Mechanism: Miners are rewarded with new bitcoins for their efforts, creating a system of economic incentives.
• Enhanced Security: Bitcoin employs SHA-256 hashing and robust encryption methods to protect transaction data and user privacy.

🌐 The Legacy and Impact

The influence of "B-Money" on Bitcoin is profound, as many of Dai's initial ideas are integral to the functioning of modern cryptocurrencies. Satoshi Nakamoto's innovation built upon these concepts, creating a decentralized, secure, and efficient digital currency that has transformed the financial landscape.

Today, Bitcoin is widely recognized and accepted, with a market capitalization surpassing $500 billion. 🌍💸 It has sparked a global movement towards decentralization, privacy, and financial inclusion, paving the way for countless other cryptocurrencies and blockchain applications.

🔗 Key Takeaways

• Conceptual Roots: Bitcoin's development was heavily inspired by Wei Dai's "B-Money" paper, incorporating ideas about cryptographic security, decentralized networks, and economic incentives.
• Technological Advancements: Satoshi Nakamoto's implementation of these concepts led to the creation of a functioning digital currency, with significant improvements in security and efficiency.
• Ongoing Evolution: The legacy of "B-Money" and Bitcoin continues to shape the future of digital finance, influencing new innovations and applications in the blockchain space.

📈 Current Trends

As Bitcoin continues to evolve, it remains at the forefront of the cryptocurrency revolution. Innovations in blockchain technology, growing institutional interest, and increasing adoption are driving the future of digital currencies.

The journey from "B-Money" to Bitcoin exemplifies the power of visionary ideas and technological advancements in shaping the future of finance. Stay tuned as we continue to explore and experience the evolution of digital currency. 🚀🔍💡

Pequenos problemas que o Estado cria para a sociedade e que não são sempre lembrados

- **vale-transporte**: transferir o custo com o transporte do funcionário para um terceiro o estimula a morar longe de onde trabalha, já que morar perto é normalmente mais caro e a economia com transporte é inexistente.
- **atestado médico**: o direito a faltar o trabalho com atestado médico cria a exigência desse atestado para todas as situações, substituindo o livre acordo entre patrão e empregado e sobrecarregando os médicos e postos de saúde com visitas desnecessárias de assalariados resfriados.
- **prisões**: com dinheiro mal-administrado, burocracia e péssima alocação de recursos -- problemas que empresas privadas em competição (ou mesmo sem qualquer competição) saberiam resolver muito melhor -- o Estado fica sem presídios, com os poucos existentes entupidos, muito acima de sua alocação máxima, e com isto, segundo a bizarra corrente de responsabilidades que culpa o juiz que condenou o criminoso por sua morte na cadeia, juízes deixam de condenar à prisão os bandidos, soltando-os na rua.
- **justiça**: entrar com processos é grátis e isto faz proliferar a atividade dos advogados que se dedicam a criar problemas judiciais onde não seria necessário e a entupir os tribunais, impedindo-os de fazer o que mais deveriam fazer.
- **justiça**: como a justiça só obedece às leis e ignora acordos pessoais, escritos ou não, as pessoas não fazem acordos, recorrem sempre à justiça estatal, e entopem-na de assuntos que seriam muito melhor resolvidos entre vizinhos.
- **leis civis**: as leis criadas pelos parlamentares ignoram os costumes da sociedade e são um incentivo a que as pessoas não respeitem nem criem normas sociais -- que seriam maneiras mais rápidas, baratas e satisfatórias de resolver problemas.
- **leis de trãnsito**: quanto mais leis de trânsito, mais serviço de fiscalização são delegados aos policiais, que deixam de combater crimes por isto (afinal de contas, eles não querem de fato arriscar suas vidas combatendo o crime, a fiscalização é uma excelente desculpa para se esquivarem a esta responsabilidade).
- **financiamento educacional**: é uma espécie de subsídio às faculdades privadas que faz com que se criem cursos e mais cursos que são cada vez menos recheados de algum conhecimento ou técnica útil e cada vez mais inúteis.
- **leis de tombamento**: são um incentivo a que o dono de qualquer área ou construção "histórica" destrua todo e qualquer vestígio de história que houver nele antes que as autoridades descubram, o que poderia não acontecer se ele pudesse, por exemplo, usar, mostrar e se beneficiar da história daquele local sem correr o risco de perder, de fato, a sua propriedade.
- **zoneamento urbano**: torna as cidades mais espalhadas, criando uma necessidade gigantesca de carros, ônibus e outros meios de transporte para as pessoas se locomoverem das zonas de moradia para as zonas de trabalho.
- **zoneamento urbano**: faz com que as pessoas percam horas no trânsito todos os dias, o que é, além de um desperdício, um atentado contra a sua saúde, que estaria muito melhor servida numa caminhada diária entre a casa e o trabalho.
- **zoneamento urbano**: torna ruas e as casas menos seguras criando zonas enormes, tanto de residências quanto de indústrias, onde não há movimento de gente alguma.
- **escola obrigatória + currículo escolar nacional**: emburrece todas as crianças.
- **leis contra trabalho infantil**: tira das crianças a oportunidade de aprender ofícios úteis e levar um dinheiro para ajudar a família.
- **licitações**: como não existem os critérios do mercado para decidir qual é o melhor prestador de serviço, criam-se comissões de pessoas que vão decidir coisas. isto incentiva os prestadores de serviço que estão concorrendo na licitação a tentar comprar os membros dessas comissões. isto, fora a corrupção, gera problemas reais: __(i)__ a escolha dos serviços acaba sendo a pior possível, já que a empresa prestadora que vence está claramente mais dedicada a comprar comissões do que a fazer um bom trabalho (este problema afeta tantas áreas, desde a construção de estradas até a qualidade da merenda escolar, que é impossível listar aqui); __(ii)__ o processo corruptor acaba, no longo prazo, eliminando as empresas que prestavam e deixando para competir apenas as corruptas, e a qualidade tende a piorar progressivamente.
- **cartéis**: o Estado em geral cria e depois fica refém de vários grupos de interesse. o caso dos taxistas contra o Uber é o que está na moda hoje (e o que mostra como os Estados se comportam da mesma forma no mundo todo).
- **multas**: quando algum indivíduo ou empresa comete uma fraude financeira, ou causa algum dano material involuntário, as vítimas do caso são as pessoas que sofreram o dano ou perderam dinheiro, mas o Estado tem sempre leis que prevêem multas para os responsáveis. A justiça estatal é sempre muito rígida e rápida na aplicação dessas multas, mas relapsa e vaga no que diz respeito à indenização das vítimas. O que em geral acontece é que o Estado aplica uma enorme multa ao responsável pelo mal, retirando deste os recursos que dispunha para indenizar as vítimas, e se retira do caso, deixando estas desamparadas.
- **desapropriação**: o Estado pode pegar qualquer propriedade de qualquer pessoa mediante uma indenização que é necessariamente inferior ao valor da propriedade para o seu presente dono (caso contrário ele a teria vendido voluntariamente).
- **seguro-desemprego**: se há, por exemplo, um prazo mínimo de 1 ano para o sujeito ter direito a receber seguro-desemprego, isto o incentiva a planejar ficar apenas 1 ano em cada emprego (ano este que será sucedido por um período de desemprego remunerado), matando todas as possibilidades de aprendizado ou aquisição de experiência naquela empresa específica ou ascensão hierárquica.
- **previdência**: a previdência social tem todos os defeitos de cálculo do mundo, e não importa muito ela ser uma forma horrível de poupar dinheiro, porque ela tem garantias bizarras de longevidade fornecidas pelo Estado, além de ser compulsória. Isso serve para criar no imaginário geral a idéia da __aposentadoria__, uma época mágica em que todos os dias serão finais de semana. A idéia da aposentadoria influencia o sujeito a não se preocupar em ter um emprego que faça sentido, mas sim em ter um trabalho qualquer, que o permita se aposentar.
- **regulamentação impossível**: milhares de coisas são proibidas, há regulamentações sobre os aspectos mais mínimos de cada empreendimento ou construção ou espaço. se todas essas regulamentações fossem exigidas não haveria condições de produção e todos morreriam. portanto, elas não são exigidas. porém, o Estado, ou um agente individual imbuído do poder estatal pode, se desejar, exigi-las todas de um cidadão inimigo seu. qualquer pessoa pode viver a vida inteira sem cumprir nem 10% das regulamentações estatais, mas viverá também todo esse tempo com medo de se tornar um alvo de sua exigência, num estado de terror psicológico.
- **perversão de critérios**: para muitas coisas sobre as quais a sociedade normalmente chegaria a um valor ou comportamento "razoável" espontaneamente, o Estado dita regras. estas regras muitas vezes não são obrigatórias, são mais "sugestões" ou limites, como o salário mínimo, ou as 44 horas semanais de trabalho. a sociedade, porém, passa a usar esses valores como se fossem o normal. são raras, por exemplo, as ofertas de emprego que fogem à regra das 44h semanais.
- **inflação**: subir os preços é difícil e constrangedor para as empresas, pedir aumento de salário é difícil e constrangedor para o funcionário. a inflação força as pessoas a fazer isso, mas o aumento não é automático, como alguns economistas podem pensar (enquanto alguns outros ficam muito satisfeitos de que esse processo seja demorado e difícil).
- **inflação**: a inflação destrói a capacidade das pessoas de julgar preços entre concorrentes usando a própria memória.
- **inflação**: a inflação destrói os cálculos de lucro/prejuízo das empresas e prejudica enormemente as decisões empresariais que seriam baseadas neles.
- **inflação**: a inflação redistribui a riqueza dos mais pobres e mais afastados do sistema financeiro para os mais ricos, os bancos e as megaempresas.
- **inflação**: a inflação estimula o endividamento e o consumismo.
- **lixo:** ao prover coleta e armazenamento de lixo "grátis para todos" o Estado incentiva a criação de lixo. se tivessem que pagar para que recolhessem o seu lixo, as pessoas (e conseqüentemente as empresas) se empenhariam mais em produzir coisas usando menos plástico, menos embalagens, menos sacolas.
- **leis contra crimes financeiros:** ao criar legislação para dificultar acesso ao sistema financeiro por parte de criminosos a dificuldade e os custos para acesso a esse mesmo sistema pelas pessoas de bem cresce absurdamente, levando a um percentual enorme de gente incapaz de usá-lo, para detrimento de todos -- e no final das contas os grandes criminosos ainda conseguem burlar tudo.

I think of Flash Fiction as pressing the subconscious into duty.

It has been rewarding for me. Tomorrow is Flash August Fiction where I will do 30 brand-new stories, podcasted, in 30 days. In February, I did Flash Fiction February[FFF], which was 29.

Here is the link for this podcast: https://commercialherschel.substack.com/p/a-flash-fiction-formula

What I learned from FFF and how a formula emerged.

Don’t be cheap. Don’t be lazy. Write a real ending. Don’t end your story with some cheap, traumatic other-worldly ending where a monster or an alien kills everyone, or there’s a car accident and everyone dies. Actually reveal something, go ahead and be clever and articulate. Write as much as you need to make that happen.

Not Like a Typical Story

It is more prompt-driven, and less premise-driven. Most stories are beginning, middle, ending. FF is different. It’s more like two parts. Either a beginning and then combine the middle and the ending, or, I combine the beginning and the middle, and then have an ending. I’m not sure if there’s a purposeful decision. If my mind is more chaotic, it’s usually the latter.

It’s Usually a Two-part Formula

Mystery- Reveal Problem- Solution Conflict- Resolution Obstacle- Removal /Overcoming Enemy- Victory Humor: Build-up- Punchline.

What are the prompts for stories?

Anything Objects Dreams First thought I wake up with. Conversations from anywhere, such as Troubled Minds Newsletter ‘s discord, for instance. Memories Relationship Dynamics Continuations of series’ or sequels from past stories.

That’s pretty much what I know about writing flash fiction as opposed to more planned out, premise-driven fiction. There is a lot more detail and nuance in the actual podcast episode that goes with this post.

I went on in there about how writing works to help you reveal things in your mind you might not be cognizant of right away. HERE is the episode I mentioned, which is the 2nd episode I made, called Subconscious Problem Solving : https://commercialherschel.substack.com/p/subconscious-problem-solving

If you see my picture, my name, or anyone subtely implying they are me anywhere online that isn't the following websites: icum.to videos.icum.to tubgurl.com endchan.gg/ashleyj that is NOT me. I do not use any form of social media*, I do not have "secret" profiles, I do not use realtime chat. There have been numerous times people thought they were talking to me. People can easily impersonate me because I talk about my interests and have photos/videos of me online. I do not play online video games, I do not use/like realtime chat, I do not use social media. It is not me. Usernames similar to my name/interests are not me. If you really think you are talking to me on a game, Discord, social media, etc. call my phone number (725-286-3278) or email me and I will verify that I am not the imposter.

*Social media being any large or small social platform, be it proprietary or open source. Popular ones include Facebook, Instagram, TikTok, Discord, Twitter, or Mastodon instances. I appreciate open source efforts for a more free social media, however, I do not like the social media platform style for a number of reasons.

If you are curious as to why I do not use social media, please read this.

Drivechain

Understanding Drivechain requires a shift from the paradigm most bitcoiners are used to. It is not about "trustlessness" or "mathematical certainty", but game theory and incentives. (Well, Bitcoin in general is also that, but people prefer to ignore it and focus on some illusion of trustlessness provided by mathematics.)

Here we will describe the basic mechanism (simple) and incentives (complex) of "hashrate escrow" and how it enables a 2-way peg between the mainchain (Bitcoin) and various sidechains.

The full concept of "Drivechain" also involves blind merged mining (i.e., the sidechains mine themselves by publishing their block hashes to the mainchain without the miners having to run the sidechain software), but this is much easier to understand and can be accomplished either by the BIP-301 mechanism or by the Spacechains mechanism.

How does hashrate escrow work from the point of view of Bitcoin?

A new address type is created. Anything that goes in that is locked and can only be spent if all miners agree on the Withdrawal Transaction (WT^) that will spend it for 6 months. There is one of these special addresses for each sidechain.

To gather miners' agreement bitcoind keeps track of the "score" of all transactions that could possibly spend from that address. On every block mined, for each sidechain, the miner can use a portion of their coinbase to either increase the score of one WT^ by 1 while decreasing the score of all others by 1; or they can decrease the score of all WT^s by 1; or they can do nothing.

Once a transaction has gotten a score high enough, it is published and funds are effectively transferred from the sidechain to the withdrawing users.

If a timeout of 6 months passes and the score doesn't meet the threshold, that WT^ is discarded.

What does the above procedure mean?

It means that people can transfer coins from the mainchain to a sidechain by depositing to the special address. Then they can withdraw from the sidechain by making a special withdraw transaction in the sidechain.

The special transaction somehow freezes funds in the sidechain while a transaction that aggregates all withdrawals into a single mainchain WT^, which is then submitted to the mainchain miners so they can start voting on it and finally after some months it is published.

Now the crucial part: the validity of the WT^ is not verified by the Bitcoin mainchain rules, i.e., if Bob has requested a withdraw from the sidechain to his mainchain address, but someone publishes a wrong WT^ that instead takes Bob's funds and sends them to Alice's main address there is no way the mainchain will know that. What determines the "validity" of the WT^ is the miner vote score and only that. It is the job of miners to vote correctly -- and for that they may want to run the sidechain node in SPV mode so they can attest for the existence of a reference to the WT^ transaction in the sidechain blockchain (which then ensures it is ok) or do these checks by some other means.

What? 6 months to get my money back?

Yes. But no, in practice anyone who wants their money back will be able to use an atomic swap, submarine swap or other similar service to transfer funds from the sidechain to the mainchain and vice-versa. The long delayed withdraw costs would be incurred by few liquidity providers that would gain some small profit from it.

Why bother with this at all?

Drivechains solve many different problems:

It enables experimentation and new use cases for Bitcoin

Issued assets, fully private transactions, stateful blockchain contracts, turing-completeness, decentralized games, some "DeFi" aspects, prediction markets, futarchy, decentralized and yet meaningful human-readable names, big blocks with a ton of normal transactions on them, a chain optimized only for Lighting-style networks to be built on top of it.

These are some ideas that may have merit to them, but were never actually tried because they couldn't be tried with real Bitcoin or inferfacing with real bitcoins. They were either relegated to the shitcoin territory or to custodial solutions like Liquid or RSK that may have failed to gain network effect because of that.

It solves conflicts and infighting

Some people want fully private transactions in a UTXO model, others want "accounts" they can tie to their name and build reputation on top; some people want simple multisig solutions, others want complex code that reads a ton of variables; some people want to put all the transactions on a global chain in batches every 10 minutes, others want off-chain instant transactions backed by funds previously locked in channels; some want to spend, others want to just hold; some want to use blockchain technology to solve all the problems in the world, others just want to solve money.

With Drivechain-based sidechains all these groups can be happy simultaneously and don't fight. Meanwhile they will all be using the same money and contributing to each other's ecosystem even unwillingly, it's also easy and free for them to change their group affiliation later, which reduces cognitive dissonance.

It solves "scaling"

Multiple chains like the ones described above would certainly do a lot to accomodate many more transactions that the current Bitcoin chain can. One could have special Lightning Network chains, but even just big block chains or big-block-mimblewimble chains or whatnot could probably do a good job. Or even something less cool like 200 independent chains just like Bitcoin is today, no extra features (and you can call it "sharding"), just that would already multiply the current total capacity by 200.

Use your imagination.

It solves the blockchain security budget issue

The calculation is simple: you imagine what security budget is reasonable for each block in a world without block subsidy and divide that for the amount of bytes you can fit in a single block: that is the price to be paid in satoshis per byte. In reasonable estimative, the price necessary for every Bitcoin transaction goes to very large amounts, such that not only any day-to-day transaction has insanely prohibitive costs, but also Lightning channel opens and closes are impracticable.

So without a solution like Drivechain you'll be left with only one alternative: pushing Bitcoin usage to trusted services like Liquid and RSK or custodial Lightning wallets. With Drivechain, though, there could be thousands of transactions happening in sidechains and being all aggregated into a sidechain block that would then pay a very large fee to be published (via blind merged mining) to the mainchain. Bitcoin security guaranteed.

It keeps Bitcoin decentralized

Once we have sidechains to accomodate the normal transactions, the mainchain functionality can be reduced to be only a "hub" for the sidechains' comings and goings, and then the maximum block size for the mainchain can be reduced to, say, 100kb, which would make running a full node very very easy.

Can miners steal?

Yes. If a group of coordinated miners are able to secure the majority of the hashpower and keep their coordination for 6 months, they can publish a WT^ that takes the money from the sidechains and pays to themselves.

Will miners steal?

No, because the incentives are such that they won't.

Although it may look at first that stealing is an obvious strategy for miners as it is free money, there are many costs involved:

1. The cost of ceasing blind-merged mining returns -- as stealing will kill a sidechain, all the fees from it that miners would be expected to earn for the next years are gone;
2. The cost of Bitcoin price going down: If a steal is successful that will mean Drivechains are not safe, therefore Bitcoin is less useful, and miner credibility will also be hurt, which are likely to cause the Bitcoin price to go down, which in turn may kill the miners' businesses and savings;
3. The cost of coordination -- assuming miners are just normal businesses, they just want to do their work and get paid, but stealing from a Drivechain will require coordination with other miners to conduct an immoral act in a way that has many pitfalls and is likely to be broken over the months;
4. The cost of miners leaving your mining pool: when we talked about "miners" above we were actually talking about mining pools operators, so they must also consider the risk of miners migrating from their mining pool to others as they begin the process of stealing;
5. The cost of community goodwill -- when participating in a steal operation, a miner will suffer a ton of backlash from the community. Even if the attempt fails at the end, the fact that it was attempted will contribute to growing concerns over exaggerated miners power over the Bitcoin ecosystem, which may end up causing the community to agree on a hard-fork to change the mining algorithm in the future, or to do something to increase participation of more entities in the mining process (such as development or cheapment of new ASICs), which have a chance of decreasing the profits of current miners.

Another point to take in consideration is that one may be inclined to think a newly-created sidechain or a sidechain with relatively low usage may be more easily stolen from, since the blind merged mining returns from it (point 1 above) are going to be small -- but the fact is also that a sidechain with small usage will also have less money to be stolen from, and since the other costs besides 1 are less elastic at the end it will not be worth stealing from these too.

All of the above consideration are valid only if miners are stealing from good sidechains. If there is a sidechain that is doing things wrong, scamming people, not being used at all, or is full of bugs, for example, that will be perceived as a bad sidechain, and then miners can and will safely steal from it and kill it, which will be perceived as a good thing by everybody.

What do we do if miners steal?

Paul Sztorc has suggested in the past that a user-activated soft-fork could prevent miners from stealing, i.e., most Bitcoin users and nodes issue a rule similar to this one to invalidate the inclusion of a faulty WT^ and thus cause any miner that includes it in a block to be relegated to their own Bitcoin fork that other nodes won't accept.

This suggestion has made people think Drivechain is a sidechain solution backed by user-actived soft-forks for safety, which is very far from the truth. Drivechains must not and will not rely on this kind of soft-fork, although they are possible, as the coordination costs are too high and no one should ever expect these things to happen.

If even with all the incentives against them (see above) miners do still steal from a good sidechain that will mean the failure of the Drivechain experiment. It will very likely also mean the failure of the Bitcoin experiment too, as it will be proven that miners can coordinate to act maliciously over a prolonged period of time regardless of economic and social incentives, meaning they are probably in it just for attacking Bitcoin, backed by nation-states or something else, and therefore no Bitcoin transaction in the mainchain is to be expected to be safe ever again.

Why use this and not a full-blown trustless and open sidechain technology?

Because it is impossible.

If you ever heard someone saying "just use a sidechain", "do this in a sidechain" or anything like that, be aware that these people are either talking about "federated" sidechains (i.e., funds are kept in custody by a group of entities) or they are talking about Drivechain, or they are disillusioned and think it is possible to do sidechains in any other manner.

No, I mean a trustless 2-way peg with correctness of the withdrawals verified by the Bitcoin protocol!

That is not possible unless Bitcoin verifies all transactions that happen in all the sidechains, which would be akin to drastically increasing the blocksize and expanding the Bitcoin rules in tons of ways, i.e., a terrible idea that no one wants.

What about the Blockstream sidechains whitepaper?

Yes, that was a way to do it. The Drivechain hashrate escrow is a conceptually simpler way to achieve the same thing with improved incentives, less junk in the chain, more safety.

Isn't the hashrate escrow a very complex soft-fork?

Yes, but it is much simpler than SegWit. And, unlike SegWit, it doesn't force anything on users, i.e., it isn't a mandatory blocksize increase.

Why should we expect miners to care enough to participate in the voting mechanism?

Because it's in their own self-interest to do it, and it costs very little. Today over half of the miners mine RSK. It's not blind merged mining, it's a very convoluted process that requires them to run a RSK full node. For the Drivechain sidechains, an SPV node would be enough, or maybe just getting data from a block explorer API, so much much simpler.

What if I still don't like Drivechain even after reading this?

That is the entire point! You don't have to like it or use it as long as you're fine with other people using it. The hashrate escrow special addresses will not impact you at all, validation cost is minimal, and you get the benefit of people who want to use Drivechain migrating to their own sidechains and freeing up space for you in the mainchain.

bitcoind decentralization

It is better to have multiple curator teams, with different vetting processes and release schedules for bitcoind than a single one.

"More eyes on code", "Contribute to Core", "Everybody should audit the code".

All these points repeated again and again fell to Earth on the day it was discovered that Bitcoin Core developers merged a variable name change from "blacklist" to "blocklist" without even discussing or acknowledging the fact that that innocent pull request opened by a sybil account was a social attack.

After a big lot of people manifested their dissatisfaction with that event on Twitter and on GitHub, most Core developers simply ignored everybody's concerns or even personally attacked people who were complaining.

The event has shown that:

1) Bitcoin Core ultimately rests on the hands of a couple maintainers and they decide what goes on the GitHub repository[^pr-merged-very-quickly] and the binary releases that will be downloaded by thousands; 2) Bitcoin Core is susceptible to social attacks; 2) "More eyes on code" don't matter, as these extra eyes can be ignored and dismissed.

Solution: bitcoind decentralization

If usage was spread across 10 different bitcoind flavors, the network would be much more resistant to social attacks to a single team.

This has nothing to do with the question on if it is better to have multiple different Bitcoin node implementations or not, because here we're basically talking about the same software.

Multiple teams, each with their own release process, their own logo, some subtle changes, or perhaps no changes at all, just a different name for their bitcoind flavor, and that's it.

Every day or week or month or year, each flavor merges all changes from Bitcoin Core on their own fork. If there's anything suspicious or too leftist (or perhaps too rightist, in case there's a leftist bitcoind flavor), maybe they will spot it and not merge.

This way we keep the best of both worlds: all software development, bugfixes, improvements goes on Bitcoin Core, other flavors just copy. If there's some non-consensus change whose efficacy is debatable, one of the flavors will merge on their fork and test, and later others -- including Core -- can copy that too. Plus, we get resistant to attacks: in case there is an attack on Bitcoin Core, only 10% of the network would be compromised. the other flavors would be safe.

Run Bitcoin Knots

The first example of a bitcoind software that follows Bitcoin Core closely, adds some small changes, but has an independent vetting and release process is Bitcoin Knots, maintained by the incorruptible Luke DashJr.

Next time you decide to run bitcoind, run Bitcoin Knots instead and contribute to bitcoind decentralization!

Is It A Payment Terminal Or A Sign?

Fiat is my only shitcoin. I am a shitcoin minimalist. The problem is, most people don’t want bitcoin. Most corporations are fiat maxis. Most business owners are fiat maxis. To be honest, most bitcoiners care more about the fiat price than running a node. Most bitcoiners also feel as if they don’t have enough, myself included. The problem with using bitcoin as a medium of exchange is the coincidence of wants. Bitcoiners don’t want to spend bitcoin. Shops want fiat. There is no coincidence of wants. The corporations don’t want to mess around with converting their payment terminals into a bitcoin accepting machine. - They don’t want to spend time training employees how to use bitcoin. - They Think it’s bad for the environment unless you mine bitcoin with Tesla batteries or something. - It’s too slow. - There are only 7 transactions per second…

They’re wrong, but the suits are still stuck with 2015 arguments.

I still believe we can use the lightning network to pay for coffee. This can be done very easily. I will not need every business around me to accept bitcoin. I don’t need them to HODL. I just need about ten places near me, where I can spend my bitcoin.

Strike Tried To Fix This

A couple years ago, Jack Mallers told Matt Odell we would soon be buying groceries at WholeFoods and cheeseburgers at Wendy’s. He built it like the Field of Dreams, but they didn’t come. It could totally work, but they just don’t get it and like Satoshi said, “If you don’t get it or don’t believe me, I’m sorry, I don’t have time to convince you.”

https://fountain.fm/clip/rOwhyibbPOTehTXSfwPY

Maybe we can't buy overpriced groceries at Whole Foods yet, but it is possible to add Strike to some payment terminals like Clover. How would that work though? “Hi. I’ve listened to more bitcoin podcasts than anybody you know. May I please hack your Clover machine so I pay you in bitcoin?”

It's not going to work.

I know the government collects a sales tax( A.K.A. capital gains). According to the chapwood index, inflation is not much less than this sales tax where I live. It was even higher than 15% for a while. The point is, I want to spend bitcoin. Fewer businesses accept bitcoin than American Express. There is no coincidence of wants and most business owners don’t want me hacking their point of sale machines.

BTCpaySigns

Bitcoin is awesome, but few understand this. Most people don’t want to put in the 100 hours to learn about bitcoin. It’s a sign of the times. Speaking of signs, most businesses understand them. Here are businesses that sell signs to no-coiners. People like signs. I read that most people choose fast food restaurants by signs in Fast Food Nation. Signs are an old idea. We see then on the road and at brick and mortar businesses.

Apps are also ubiquitous. It occurred to me that I can pay a shopkeeper by using a lightning address they obtain from Strike. I can also pay them with their Strike Tipping page at https://stike.me/theirstrikeusername. For example, you can send the personwith the username Odell sats on strike at https://strike.me/odell. I haven't verified this username belongs to the person behind npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx. Regardless, the business owner receives the sats right away, but he or she can choose to accept incoming payments in bitcoin or fiat. Of course, I think they should keep the sats and put them into self-custody, but I don’t have time to convince anybody.

Here is an example of how this sign works.

My goal is to find 10 local small business that will allow me to pay for coffee, groceries, or hamburgers using bitcoin. I'm not trying to orange pill Starbucks. I want other people to do this too.

Here's the plan.

1) Onboard a local business onto Strike. Show them how to use it. Don't try to convince them. Let them accept dollars or bitcoin. If they choose dollars and bitcoin does what we think it will, we won't need to convince them.

2) Make them a sign, or buy one from https://btcpaysigns.com and I will make you one. I'll just need the Strike Username.

3) Pay with bitcoin. If you prefer to pay with fiat, for tax purposes, or because you don't hace enough bitcoin, use the Strike app yourself. You can also keep fiat on the Stike app while using the ligntning network as a payment rail. It will turn your dirty fiat into bitcoin and give the business owner the form of payment they prefer. 4) Bring them business. Bring a meetup to the business. Put them on BTCpayMaps.org. Let all the bitcoiners you know they accept bitcoin. If accepting bitcoin does not bring the business more customers, they will not have an incentive to adopt the bitcoin standard.

See the whole Fruits of the Spirit Series

Once again here are the fruits of the Spirit as defined in Galatians 5.

But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. (Galatians 5:22-23)

When going through the fruits of the Spirit, I like to always start with God’s Word, the Bible. In the case of faithfulness, I had a harder time finding verses that clearly defined faithfulness, so we are going to start with a dictionary definition and then fine tune it using the Bible.

Definition

From Dictionary.com

faithfulness

noun

• lasting loyalty and trustworthiness in relationships, especially marriage and friendship:
• the fact or quality of being true to one’s word or commitments, as to what one has pledged to do, professes to believe, etc.::
• the fact or quality of being dedicated and steadfast in performing one’s duty, working for a cause, etc.::
• the quality of adhering to fact, a standard, or an original; accuracy::

Now lets start tweaking this definition. Biblical faithfulness does include “loyalty and trustworthiness in relationships” (especially our relationship to God). It does include “being true to one’s word or commitments” (especially commitments to God). It does include being dedicated and steadfast performing one’s duty (especially to God) and working for a cause (God’s will). It does include “adhering to fact, a standard, or an original” (God’s standard as defined in the Bible and lived out by Jesus).

I've heard lots of Christians make the statement, “love is an action (or choice), not a feeling.” I’d argue that faithfulness is the same. It is an action. It is the living out of our faith in an active, purposeful, and consistent manner in accordance with God’s will.

Faithfulness Includes Works

Although James doesn’t actually use the word faithfulness, I think this passage does help with our understanding of faithfulness.

What use is it, my brethren, if someone says he has faith but he has no works? Can that faith save him? If a brother or sister is without clothing and in need of daily food, and one of you says to them, “Go in peace, be warmed and be filled,” and yet you do not give them what is necessary for their body, what use is that? Even so faith, if it has no works, is dead, being by itself.

But someone may well say, “You have faith and I have works; show me your faith without the works, and I will show you my faith by my works.” You believe that God is one. You do well; the demons also believe, and shudder. But are you willing to recognize, you foolish fellow, that faith without works is useless? Was not Abraham our father justified by works when he offered up Isaac his son on the altar? You see that faith was working with his works, and as a result of the works, faith was perfected; and the Scripture was fulfilled which says, “And Abraham believed God, and it was reckoned to him as righteousness,” and he was called the friend of God. You see that a man is justified by works and not by faith alone. In the same way, was not Rahab the harlot also justified by works when she received the messengers and sent them out by another way? For just as the body without the spirit is dead, so also faith without works is dead. (James 2:14-26)

If we are saved, we should have the fruits of the Spirit. If we have the fruits of the Spirit, we should have faithfulness. If we have faithfulness, our words and actions should show our faith. “If someone says he has faith but he has no works? Can that faith save him?” If we have saving faith, our works should show it and that is faithfulness. If our faith doesn’t change the way we live, it isn’t saving faith. “If someone says he has faith but he has no works? Can that faith save him?” No it can’t. It is like the faith (belief) of the demons, and it does not lead to salvation.

A faith, without faithful works, is no faith at all. It is unfaithfulness. “Faith without works is useless.” Faithfulness is a sign that our faith is being perfected by God. “Faith was working with his works, and as a result of the works, faith was perfected.”

I’d argue that Biblical faithfulness is faith working through the power of the Spirit.

This command I entrust to you, Timothy, my son, in accordance with the prophecies previously made concerning you, that by them you fight the good fight, keeping faith and a good conscience, which some have rejected and suffered shipwreck in regard to their faith. Among these are Hymenaeus and Alexander, whom I have handed over to Satan, so that they will be taught not to blaspheme. (1 Timothy 1:18-20)

“Fight the good fight, keeping faith and a good conscience.” Our Spirit-filled faithfulness leads to never giving up despite the hardship, never losing our faith in God, His will, and His goodness, and obeying God’s law so we can have a good conscience. 1 Timothy says that those who are not faithful may be “handed over to Satan, so that they will be taught not to blaspheme.” We are called to be faithful always and we are enabled, by the Spirit, to be faithful.

Choose Faithfulness

We do have to chose to be faithful, not just sit around, following the easy path, waiting for the Spirit to enliven us. We need to seek God. We need to study His word. We need pray for wisdom and strength. We need to follow God’s leading. Faithfulness is an action.

My soul cleaves to the dust;
Revive me according to Your word.
I have told of my ways, and You have answered me;
Teach me Your statutes.
Make me understand the way of Your precepts,
So I will meditate on Your wonders.
My soul weeps because of grief;
Strengthen me according to Your word.
Remove the false way from me,
And graciously grant me Your law.
I have chosen the faithful way;
I have placed Your ordinances before me.
I cling to Your testimonies;
O Lord, do not put me to shame!
I shall run the way of Your commandments,
For You will enlarge my heart. (Psalm 119:25-32)

Chose the faithful way. Actively choose to be faithful and He will enable you to be faithful.

God’s Example

One way we learn to be faithful is by seeing how God is faithful. We can look at how God was faithful with His promises to Adam, to Noah, to Abraham, to Isaac, and to Jacob (Israel). We can see how He was faithful to the nation Israel, even when they were not faithful. We can see how He was faithful with his followers in the New Testament.

It is a trustworthy statement:
For if we died with Him, we will also live with Him;
If we endure, we will also reign with Him;
If we deny Him, He also will deny us;
If we are faithless, He remains faithful, for He cannot deny Himself. (2 Timothy 2:11-13)

God is faithfulness and we are made in His image. Sin has marred our Godly image, but faith in Jesus and the covering of His blood enables us to show that faithfulness again. When talking to Nicodemus, Jesus told him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” (John 3:3) Part of being born again is being changed to become more like the image of God, and God is faithful. We must be faithful in the same way.

Know therefore that the Lord your God, He is God, the faithful God, who keeps His covenant and His lovingkindness to a thousandth generation with those who love Him and keep His commandments; but repays those who hate Him to their faces, to destroy them; He will not delay with him who hates Him, He will repay him to his face. Therefore, you shall keep the commandment and the statutes and the judgments which I am commanding you today, to do them. (Deuteronomy 7:9-11)

Be faithful as God is faithful and keep His commandments as He keeps His promises.

Do not fear what you are about to suffer. Behold, the devil is about to cast some of you into prison, so that you will be tested, and you will have tribulation for ten days. Be faithful until death, and I will give you the crown of life. He who has an ear, let him hear what the Spirit says to the churches. He who overcomes will not be hurt by the second death.’ (Revelation 2:10-11)

Our faithfulness should be dependent on His faithfulness and not on our circumstances. We are told up front that most of us will face difficult times, even more so as the end times approach (which I believe is true of this generation). We will be persecuted. We will be disciplined. We will be pruned. We will be tested. We will die (sooner or later). Despite this, He will bring us through to glory. Be faithful unto death, whether a natural death at an old age or as a martyr for Christ.

Blessings of Faithfulness

Luckily faithfulness is not all doom and gloom. God does promise blessings for those who are faithful. Some blessings may be in the present; some may be in the future; but we will be blessed.

He who tills his land will have plenty of food,
But he who follows empty pursuits will have poverty in plenty.
A faithful man will abound with blessings,
But he who makes haste to be rich will not go unpunished. (Proverbs 28:19-20)

Lastly I leave with you two verses of encouragement relating to faithfulness:

And he said to me, “These words are faithful and true”; and the Lord, the God of the spirits of the prophets, sent His angel to show to His bond-servants the things which must soon take place. (Revelation 22:6)

and

I will betroth you to Me forever; Yes, I will betroth you to Me in righteousness and in justice, In lovingkindness and in compassion, And I will betroth you to Me in faithfulness. Then you will know the Lord. (Hosea 2:19-20)

@ 8d34bd24:414be32b

I’ve heard lots of people complain about negative things that happen to them and heard them ask why something bad happened to them when they were basically “good” people. I don’t think they fully understand God’s blessings. God’s blessings are amazingly good, but they aren’t necessarily what we think they are or what we might ask for.

Now lets look at the woman who is considered the most blessed in history.

Now in the sixth month the angel Gabriel was sent from God to a city in Galilee called Nazareth, to a virgin engaged to a man whose name was Joseph, of the descendants of David; and the virgin’s name was Mary. And coming in, he said to her, “Greetings, favored one! The Lord is with you.” (Luke 1:26-28)

Mary, the mother of Jesus, is called the favored one. She is the most blessed of all. After she conceived of the Holy Spirit, she went to visit her relative, Elizabeth, who was also pregnant.

Now at this time Mary arose and went in a hurry to the hill country, to a city of Judah, and entered the house of Zacharias and greeted Elizabeth. When Elizabeth heard Mary’s greeting, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit. And she cried out with a loud voice and said, “Blessed are you among women, and blessed is the fruit of your womb! And how has it happened to me, that the mother of my Lord would come to me? For behold, when the sound of your greeting reached my ears, the baby leaped in my womb for joy. 45And blessed is she who believed that there would be a fulfillment of what had been spoken to her by the Lord.” (Luke 1:39-45)

Mary was called blessed among women, her child was called blessed, and she was called blessed for believing the Angel who prophesied her pregnancy despite the fact that she had never “known” a man. You could argue that she was the most blessed woman of all time because she was the mother of Jesus making her the physical mother of God.

Although looking at her life from the outside, most people would not call her blessed. She was impregnated by the Holy Spirit, not a man, so the people around her thought she was guilty of adultery and that she was an immoral woman. Her husband (fiance in modern terms, but in that day it was treated as married and a legal contract) almost divorced her. Although not mentioned explicitly, textual evidence suggests her husband died early, leaving her a widow possibly even with multiple kids at home. Her eldest son was crucified and died a most horrific, embarrassing, and cruel death in front of her. Based on Jesus asking His apostle John to take care of His mother, it suggests her other sons were not doing their duty to provide for their widowed mother.

Does this sound like a blessing? Most people would say, “No,” but the Bible calls her blessed. Why is that?

Mary was used of God to fulfill His awesome purpose and to provide salvation to people around the world and throughout time. Mary was a part of this work and is honored for allowing herself to be used in this way. This is a blessing. She got to spend 33 years with the creator of the world. She got to hear His wisdom. She had the best behaved child in history. Yes, she was truly blessed and I believe she knew she was blessed.

So often in life we complain about the hardships in our life. We complain that things aren’t fair. Instead, we need to look and see what God is doing and join Him. We need to study God’s word, obey His command, and love others. When we are fully immersed in His will and His plan, we won’t hardly notice all the incumbent hardships that almost always come with a life fully devoted to God.

A Godly life isn’t an easy life, but it is a blessed life.

Go, and be blessed by God.

Trust Jesus.

SummaDB

This was a hierarchical database server similar to the original Firebase. Records were stored on a LevelDB on different paths, like:

• /fruits/banana/color: yellow
• /fruits/banana/flavor: sweet

And could be queried by path too, using HTTP, for example, a call to http://hostname:port/fruits/banana, for example, would return a JSON document like

json { "color": "yellow", "flavor": "sweet" }

While a call to /fruits would return

json { "banana": { "color": "yellow", "flavor": "sweet" } }

POST, PUT and PATCH requests also worked.

In some cases the values would be under a special "_val" property to disambiguate them from paths. (I may be missing some other details that I forgot.)

GraphQL was also supported as a query language, so a query like

graphql query { fruits { banana { color } } }

would return {"fruits": {"banana": {"color": "yellow"}}}.

SummulaDB

SummulaDB was a browser/JavaScript build of SummaDB. It ran on the same Go code compiled with GopherJS, and using PouchDB as the storage backend, if I remember correctly.

It had replication between browser and server built-in, and one could replicate just subtrees of the main tree, so you could have stuff like this in the server:

json { "users": { "bob": {}, "alice": {} } }

And then only allow Bob to replicate /users/bob and Alice to replicate /users/alice. I am sure the require auth stuff was also built in.

There was also a PouchDB plugin to make this process smoother and data access more intuitive (it would hide the _val stuff and allow properties to be accessed directly, today I wouldn't waste time working on these hidden magic things).

The computed properties complexity

The next step, which I never managed to get fully working and caused me to give it up because of the complexity, was the ability to automatically and dynamically compute materialized properties based on data in the tree.

The idea was partly inspired on CouchDB computed views and how limited they were, I wanted a thing that would be super powerful, like, given

json { "matches": { "1": { "team1": "A", "team2": "B", "score": "2x1", "date": "2020-01-02" }, "1": { "team1": "D", "team2": "C", "score": "3x2", "date": "2020-01-07" } } }

One should be able to add a computed property at /matches/standings that computed the scores of all teams after all matches, for example.

I tried to complete this in multiple ways but they were all adding much more complexity I could handle. Maybe it would have worked better on a more flexible and powerful and functional language, or if I had more time and patience, or more people.

On "zk-rollups" applied to Bitcoin

ZK rollups make no sense in bitcoin because there is no "cheap calldata". all data is already ~~cheap~~ expensive calldata.

There could be an onchain zk verification that allows succinct signatures maybe, but never a rollup.

What happens is: you can have one UTXO that contains multiple balances on it and in each transaction you can recreate that UTXOs but alter its state using a zk to compress all internal transactions that took place.

The blockchain must be aware of all these new things, so it is in no way "L2".

And you must have an entity responsible for that UTXO and for conjuring the state changes and zk proofs.

But on bitcoin you also must keep the data necessary to rebuild the proofs somewhere else, I'm not sure how can the third party responsible for that UTXO ensure that happens.

I think such a construct is similar to a credit card corporation: one central party upon which everybody depends, zero interoperability with external entities, every vendor must have an account on each credit card company to be able to charge customers, therefore it is not clear that such a thing is more desirable than solutions that are truly open and interoperable like Lightning, which may have its defects but at least fosters a much better environment, bringing together different conflicting parties, custodians, anyone.

NASHVILLE 2024

I've made the trek down to Bitcoin Park a number of times. It's about four and a half hours from where I live and it's not an unreasonable drive once a quarter for the incredible meetings they host down there. Other than that, I can't really justify the expenses, compounded with the time off, to go to most bigger bitcoin conferences. This past week, however, I had a steal of a deal to the Bitcoin Magazine conference, which also happened to be in Nashville. I would like to share with you all some thoughts as someone who is still fresh from their first experience meeting industrial miners.

POTTY BREAK

Going into last week, I assumed that most industrial miners had at LEAST the same general knowledge as home miners like myself about concerns for mining pool centralization. Friday afternoon, as most folks had already left the convention floor, I was waiting for my daughters to use the restroom and noticed IREN's virtual reality headsets. Curious, I held one up to my eyes to see their virtual facilities tour. I've never used a VR headset, so I was quickly under the spell and about to put the strap on the back of my head. Fortunately, I was interrupted by a voice asking what I thought. The spell was broken, I pulled the headset away, and I saw a smiling face clearly poised and ready to field my questions.

I DON'T KNOW

I told him that it was "neat," which was honestly more to downplay the experience to myself than to him. In reality, the...virtual reality seemed more impressive than I wish it did. But I cut right to the point.

"What do you mine to?" "Bitcoin." "I mean, what pools do you mine to?" "50% Foundry and 50% to AntPool." "Why those two?" "I don't know." "What would you do in the event of a 51% attack?" "I don't know."

Now, you might be asking, "how much can you expect from an employee that's clearly there to impressive investors or something?" I would answer, quite a lot! This is the face that they're putting out at a conference specifically for bitcoiners. This wasn't a green energy conference. This wasn't a venture capital conference. But even if it was one of those places, this is one of the biggest concerns for his whole industry.

THEY'LL JUST SWITCH

The premier platitude for 51% attack concerns is that if these pools go rogue, all of the miners will just switch. Well...yes...I will leave with my mighty 15TH/s fleet. Maybe folks experimenting with the fun GekkoScience projects I saw will leave with their 200GH/s fleet. Maybe we'll even get lucky, and folks that bought the Superheat water heaters will leave with their 68TH/s fleet. However, the facility in that VR headset, with 2.5 EH/s, isn't even thinking about this issue!* They have four other major sites like this.

While not a scientific study, I spent most of the day on Saturday asking other industrial miners similar questions. For the most part, I got similar responses. To their credit, most hosting companies said that they let their customers choose their pools. However, are those smaller miners more like me or more like IREN? I didn't get a chance to catch anyone at TeraWulf, which is using nuclear power to mine. However, if their response is also Foundry and no plan, that's ~10EH/s that's being contributed to the 51% danger.

NOT EVEN IN THEIR BEST INTEREST

I caught a pretty knowledgable employee from Syntona Friday evening and shared my concerns. He mentioned that this attitude doesn't even really line up with the financial incentives of the miners. I don't use Foundry and AntPool for reasons that are probably pretty obvious by this point in my rant, but he said they're also not the best for fees and FPPS and other reasons that started to fly over my head. He also mused that many of them would be better off solo mining anyway.

NOW WHAT?

So...is there a group that specializes in industrial miner education? Am I imagining a consulting firm waiting to happen? I feel as if I'm identifying a problem with an easy solution, but maybe some stackers here can tell me what I'm missing. I'd love to get on board with anybody that is already trying to make this happen. I'm not so presumptuous as to think I'm the first person to notice this concern, but maybe it actually is just having a fresh ear to the ground where many of you have already walked.

_{*actually, not really because I, and probably most folks like me, already mine to smaller pools}

TL;DR - Embracing Bitcoin will not be the downfall of the US financial system; rather, it will save it. This demand will be good for Bitcoin, too.

There is no doubt the largest market for Bitcoin trading is in the US. Bitcoin and dollars are traded for each other more than any other fiat-Bitcoin pair. The USD remains the highest volume asset on the global stage, however, trust in the dollar wanes on it as well.

A great amount of uncertainty remains about Bitcoin in the public, but the public is becoming increasingly aware. At some point, the "then suddenly" threshold, when uncertainty about the dollar matches the uncertainty of Bitcoin in the public eye, a great and rapid flip will occur.

Retirement Will Become Impossible Unless Backed by Unprintable Money

It is this flip that will cause enormous and unprecedented loss for at least the aging population in the US, as well as holders of large amounts of cash. Let us focus on one aspect of this great loss: social security, which is already known to be at great risk, an almost certain bankruptcy of the whole system only a few years away, and this is only if the US dollar lasts that long.

The responsibility of this failure rests on the shoulders of the US Federal Government and the Federal Reserve. Salvation for the system will only be in one manner: backing the fund with Bitcoin.

A Strategic Reserve

If the US Government funded a strategic Bitcoin reserve rather than wars, the issuance of USD could be then exchanged for payouts in the form of Bitcoin. Retirees who depend on those monthly checks could instead receive Bitcoin. This would be reparation for the theft of the wealth promised by the system to begin, and it would be an efficient way to do so.

While the USD-BTC rate is still in the 5-figures, investments into it can see returns of hundreds times by the time Social Security becomes fully defunct. This window of opportunity is quickly closing. Returns in the tens of times should still be possible for a few years, but likely not past the year 2029.

This Will Also be Good for Bitcoin

The urgency is high. To avoid a cataclysm for our aging population, the US needs Bitcoin, and because of the demand this will generate, the adoption and valuation of Bitcoin can accelerate.

This is but one mode that Bitcoin will save the US economy, and more is to come.

The problem with ION

ION is a DID method based on a thing called "Sidetree".

I can't say for sure what is the problem with ION, because I don't understand the design, even though I have read all I could and asked everybody I knew. All available information only touches on the high-level aspects of it (and of course its amazing wonders) and no one has ever bothered to explain the details. I've also asked the main designer of the protocol, Daniel Buchner, but he may have thought I was trolling him on Twitter and refused to answer, instead pointing me to an incomplete spec on the Decentralized Identity Foundation website that I had already read before. I even tried to join the DIF as a member so I could join their closed community calls and hear what they say, maybe eventually ask a question, so I could understand it, but my entrance was ignored, then after many months and a nudge from another member I was told I had to do a KYC process to be admitted, which I refused.

One thing I know is:

• ION is supposed to provide a way to rotate keys seamlessly and automatically without losing the main identity (and the ION proponents also claim there are no "master" keys because these can also be rotated).
• ION is also not a blockchain, i.e. it doesn't have a deterministic consensus mechanism and it is decentralized, i.e. anyone can publish data to it, doesn't have to be a single central server, there may be holes in the available data and the protocol doesn't treat that as a problem.
• From all we know about years of attempts to scale Bitcoins and develop offchain protocols it is clear that you can't solve the double-spend problem without a central authority or a kind of blockchain (i.e. a decentralized system with deterministic consensus).
• Rotating keys also suffer from the double-spend problem: whenever you rotate a key it is as if it was "spent", you aren't supposed to be able to use it again.

The logic conclusion of the 4 assumptions above is that ION is flawed: it can't provide the key rotation it says it can if it is not a blockchain.

แนวคิดอันนี้เกิดขึ้นหลังจากที่ผมได้รู้จัก LFS หรือ Log- structure File System มันทำให้ผมเกิดความคิดว่าในเมื่อมันสามารถที่จะเก็บ file และทุก log ของการเปลี่ยนแปลงในแต่ละไฟล์ งั้นแปลว่าในกรณีที่ file โดน encrypt มันก็น่าจะสามารถกู้คืนมาได้สิ เอ้ะแต่ถ้าเครื่องนั้นโดน ransomware ไปรอบนึงแล้วกู้คืนมาแล้วมันก็โดนอีกอยู่ดีมั้ย เลยเกิดไอเดียใหม่ว่าแล้วถ้าเราหา SSD อีกลูกมาเก็บ backup ถ้าโดน ransomware ก็ถอดไปเสียบเครื่องใหม่ก็จบ ตะตะแต่ว่า LFS เนี่ย ดั้นนนใช้ไม่ได้กับ windows หรือ Mac เอาละ ปัญหาใหม่มาอีกละ งั้นต้องทำไงล่ะ ? หึเก็บไว้บอกท้ายบทความละกัน มาทำความเข้าใจโปรเจคนี้กันทีละขั้นตอนกันดีกว่า

Log-structure File System (LFS)

เป็น File system รูปแบบหนึ่งที่จะทำการเก็บข้อมูลเป็น log และสามารถย้อนกลับได้ทุกการกระทำ นอกจากมีความถี่ในการสร้าง snapshot ที่สูงมาก จริง ๆ แล้วเหมาะกับงานประเภทที่ต้องการความต่อเนื่องหากดบัไปต้องกู้คืนได้มากที่สุดเท่าที่เป็นไปได้ แต่เพราะไอความสามารถตรงนั้นของมันนี่แหละ ที่ผมมองว่ามันน่าจะหยิบมาใช้กับการกู้คืน file หลังจากโดน ransomware ได้แน่ ๆ โดยในครั้งนี้ผมเลือกใช้เป็น NILFS2 เนื่องจากดูแล้วน่าจะเหลือตัวเดียวที่ยังพอมีการพัฒนาอยู่ 5555 รูปแบบการเก็บข้อมูลจะเหมือนกับภาพด้านล่างนี้

ตัวอย่าง: เดิมที file A: "AAAAA" จากนั้นผมได้ทำการอัพเดตข้อมูลใน file A เป็น "BBBBB" ด้วยความสามารถของ LFS มันสามารถที่จะดึง file A เวอร์ชันที่เป็น "AAAAA" กลับมาได้

นี่เป็นปัจจัยสำคัญที่ทำให้ผมมองว่า LFS เหมาะสมที่จะมาเป็นระบบไฟล์ที่ใช้ในการสำรองข้อมูล แต่อยากที่ได้กล่าวไว้ข้างต้นว่าปัญหาของระบบไฟล์นี้คือมันใช้พื้นที่เก็บข้อมูลค่อนข้างสูง และมี write speed ที่ค่อนข้างช้า ถ้าเทียบกับระบบไฟล์อื่น ๆ ในกรณีที่ความเร็วของ SSD เท่ากัน เลยมองว่าถ้าจะใช้เป็นระบบหลักในการเก็บข้อมูลทุกอย่างคงจะไม่เหมาะ เลยนำไปสู่การทำระบบโดยใช้ระบบไฟล์สองแบบที่แตกต่างกัน

System Design

อย่างที่ได้พูดถึงข้อเสียของ NILFS2 ไปข้างต้น แปลว่าถ้าอยากจะให้คอมพิวเตอร์ทำงานได้อย่างมีประสิทธิภาพคงเดิมและสามารถป้องกัน ransomware ได้ด้วยก็จำเป็นต้องมีระบบไฟล์ที่ใช้กันทั่วไปอย่าง FAT32 หรือ ext4 และใช้ SSD อีกลูกหนึ่งที่ format เป็น NILFS2 และเขียนโปรแกรมให้คอยมอนิเตอร์ทุก ๆ กิจกรรมบน user space และทุกครั้งที่เกิดการเขียนไฟล์ขึ้นให้เขียนลงใน SSD ที่เป็น NILFS2 ด้วย ดังภาพที่แสดงด้านล่างนี้

แล้วทำไมไฟล์ในลูกที่เก็บสำรองข้อมูลถึงไม่เท่ากับจำนวนไฟล์ในที่เก็บข้อมูลหลักล่ะ ? เนื่องด้วยความเร็วในการเขียนที่ค่อนข้างแตกต่างกันของทั้งสอง ผมเลยมองว่าถ้าเราเก็บในรูปแบบบล๊อกจะทำให้เก็บข้อมูลได้ไวกว่า อย่างตัวอย่างในรูป สมมุติว่าไฟล์ A มีขนาดประมาณ 3 บล๊อกใน SSD ที่เป็น nilfs2 ก็จะมี 3 ไฟล์และต้องใช้ทั้งสามไฟล์เพื่อที่จะคืนค่าไฟล์ A กลับมา ถ้าอ่านมาถึงตรงนี้อาจจะเกิดข้อสงสัยว่า แล้วจะทำให้มันยุ่งยากทำไม คัดลอกไฟล์มาใส่ก็จบแล้วมั้ย ? ก็ใช่แหละและจริง ๆ ผมคิดว่าทำแบบนั้นก็เพียงพอ แต่ว่าอย่างที่บอกไปข้างต้น ผมอยากได้ระบบที่ป้องกันได้ 100% ผมเลยเลือกที่จะมอนิเตอร์ kernel เอาไว้และเมื่อมีการเขียนไฟล์เกิดขึ้นผมต้องการดึงข้อมูลมาจากตรงนั้นเลย ไม่อยากรอถูกเขียนลงในพื้นที่เก็บข้อมูลหลักก่อนแล้วค่อยคัดลอกมา จริง ๆ ก็ด้วยเหตุผลด้านประสิทธิภาพด้วย

แล้วจะมอนิเตอร์ kernel อย่างไร ??

ในครั้งนี้ผมเลือกที่จะใช้เป็น eBPF (extended Berkeley Packet Filter) จริงแล้วเจ้า eBPF เนี่ยใช้งานได้หลากหลายเลยแหละ เรียกได้ว่าประโยชน์รอบด้านสุด ๆ ตามรูปที่แนบด้านล่างเลย

แต่ในครั้งนี้เราจะยุ่งกับมันเพียงแค่การใช้งานเพื่อสอดส่อง kernel เท่านั้น

ภาพด้านบนนี้แสดงให้เห็นจุดที่เราสามารถใช้ eBPF ในการดึงข้อมูลได้ นั่นเลยเป็นเหตุผลหลักที่ผมเลือกใช้ โดยวางการทำงานทั้งหมดของการมอนิเตอร์ไว้ดังนี้

1. ใช้ eBPF เพื่อคอยเช็คว่ามีการเขียนเกิดขึ้นมั้ยโดยการอ่านค่า flag จาก NVMe ว่ามีค่าเป็นอะไรจากนั้นนำค่าที่ได้มา XOR ด้วย mask ถ้าค่าออกมาเป็น 1 แปลว่านั่นคือ write_operation (อาจแตกต่างกันแล้วแต่ version)
2. เมื่อเช็คค่าแล้วเป็น write_operation จากนั้นก็ให้ทำการอ่านเลข sector, และขนาดของข้อมูลที่ต้องการจะเขียน
3. จากนั้นเข้าไปอ่านต่อใน Bio ลงไปยัง Bio_vec และไป Bv_page ตามลำดับ เพื่ออ่านข้อมูลทั้งหมดที่มาจากคำสั่งในการเขียนครั้งนั้น ๆ *ภาพประกอบเพิ่มเติมเพื่อใครงงว่า Bio คืออะไรข้อมูลเวลาเราเขียนจะอยู่บน page
4. ส่งข้อมูลที่ได้ทั้งหมดออกมา

เพียงเท่านี้เราก็ทำการดึงข้อมูลทุกครั้งที่เราเขียนได้แล้ว และจะนำมันเข้าสู่ขั้นตอนต่อไปในการเก็บข้อมูลลง SSD

เก็บข้อมูลและส่งไป SSD ที่เป็น nilfs2

เมื่อได้ข้อมูลมาจากการทำงานที่ได้กล่าวไว้ข้างบนแล้ว ก็จะได้ชุดข้อมูลมาชุดหนึ่ง ส่งออกมันมาจาก ebpf(C program) มาสู่ Python ต่อโดยมีขั้นตอนดังนี้

1. นำเลข sector ที่ได้มาทำการคูณด้วยขนาดของ sector เพื่อให้เราได้ logical address มา จากนั้นให้นำ logical address หารด้วยขนาดของบล๊อกเพื่อให้ได้เลขบล๊อก
2. นำข้อมูลในแต่ละ sector มาเรียงลงในบล๊อกที่มันอยู่ละบันทึกลงไปใน SSD

ตัวอย่างเพื่อให้เห็นภาพมากขึ้น สมมุติว่าข้อมูลที่ส่งกลับมาขนาด 4097 B และเริ่มเขียนที่ sector 0 (กำหนดให้ 1 sector มีขนาด 512B และ 1 Block มี 8 sector)

4097/512 = 8.xx ก็แปลว่าข้อมูลนี้ต้องเก็บใน 9 sector คือ sector 0 ถึง 8 และ 8 sector รวมเป็น 1 block แปลว่าข้อมูลใน sector 0-7จะอยู่ใน block 0 และ sector 8 จะอยู่ใน block 1 แปลว่าโปรแกรมของผมจะสร้างมาสองไฟล์คือ 0,1 จากนั้นจะทำการเติม 0 ท้ายไฟล์ 1 จนมีขนาด 4096 B เท่ากับขนาดของ block

สำหรับคนที่งงว่า sector บล๊อกคืออะไร

ให้ดูตรงรูปกลม ๆ ทางซ้ายมือจะเห็นได้ว่ามันเป็นหน่วยความจำในจานหมุน ซึ่ง sector คือหน่วยย่อยสุด และ sector รวม ๆ กันหลาย ๆ sector จะเป็น cluter บางที่ก็เรียก Tracks บางที่ก็ Block ซึ่งนี่แหละคือบล๊อกที่ผมหมายถึง

เพียงเท่านี้เราก็ได้ระบบที่สามารถป้องกัน ransomware ได้แล้ว เพราะเนื่องจากเมื่อเราโดน ransomware และไฟล์เราถูก encrypt เราก็เพียงใช้ความความสามารถของ SSD ลูกที่เป็น nilfs2 เพื่อนำไฟล์ดั้งเดิมก่อนจะถูก encrypt กับมาได้ดังรูปประกอบด้านล่างนี้

ส่งท้าย

จริง ๆ แล้วที่ผมเก็บเป็นไฟล์ block เพราะผมอยากให้ backup file สามารถเข้ากันได้กับทุกระบบไฟล์เพื่อให้สามารถใช้งานได้กับทุกระบบ ถึงจะยังทำไม่ได้ก็เหอะ 55555

Thoughts on Nostr key management

On Why I don't like NIP-26 as a solution for key management I talked about multiple techniques that could be used to tackle the problem of key management on Nostr.

Here are some ideas that work in tandem:

• NIP-41 (stateless key invalidation)
• NIP-46 (Nostr Connect)
• NIP-07 (signer browser extension)
• Connected hardware signing devices
• other things like musig or frostr keys used in conjunction with a semi-trusted server; or other kinds of trusted software, like a dedicated signer on a mobile device that can sign on behalf of other apps; or even a separate protocol that some people decide to use as the source of truth for their keys, and some clients might decide to use that automatically
• there are probably many other ideas

Some premises I have in my mind (that may be flawed) that base my thoughts on these matters (and cause me to not worry too much) are that

• For the vast majority of people, Nostr keys aren't a target as valuable as Bitcoin keys, so they will probably be ok even without any solution;
• Even when you lose everything, identity can be recovered -- slowly and painfully, but still --, unlike money;
• Nostr is not trying to replace all other forms of online communication (even though when I think about this I can't imagine one thing that wouldn't be nice to replace with Nostr) or of offline communication, so there will always be ways.
• For the vast majority of people, losing keys and starting fresh isn't a big deal. It is a big deal when you have followers and an online persona and your life depends on that, but how many people are like that? In the real world I see people deleting social media accounts all the time and creating new ones, people losing their phone numbers or other accounts associated with their phone numbers, and not caring very much -- they just find a way to notify friends and family and move on.

We can probably come up with some specs to ease the "manual" recovery process, like social attestation and explicit signaling -- i.e., Alice, Bob and Carol are friends; Alice loses her key; Bob sends a new Nostr event kind to the network saying what is Alice's new key; depending on how much Carol trusts Bob, she can automatically start following that and remove the old key -- or something like that.

---

One nice thing about some of these proposals, like NIP-41, or the social-recovery method, or the external-source-of-truth-method, is that they don't have to be implemented in any client, they can live in standalone single-purpose microapps that users open or visit only every now and then, and these can then automatically update their follow lists with the latest news from keys that have changed according to multiple methods.

@ 3bf0c63f:aefa459d

lnurl-auth explained

You may have seen the lnurl-auth spec or heard about it, but might not know how it works or what is its relationship with other lnurl protocols. This document attempts to solve that.

Relationship between lnurl-auth and other lnurl protocols

First, what is the relationship of lnurl-auth with other lnurl protocols? The answer is none, except the fact that they all share the lnurl format for specifying https URLs.

In fact, lnurl-auth is very unique in the sense that it doesn't even need a Lightning wallet to work, it is a standalone authentication protocol that can work anywhere.

How does it work

Now, how does it work? The basic idea is that each wallet has a seed, which is a random value (you may think of the BIP39 seed words, for example). Usually from that seed different keys are derived, each of these yielding a Bitcoin address, and also from that same seed may come the keys used to generate and manage Lightning channels.

What lnurl-auth does is to generate a new key from that seed, and from that a new key for each service (identified by its domain) you try to authenticate with.

That way, you effectively have a new identity for each website. Two different services cannot associate your identities.

The flow goes like this: When you visit a website, the website presents you with a QR code containing a callback URL and a challenge. The challenge should be a random value.

When your wallet scans or opens that QR code it uses the domain in the callback URL plus the main lnurl-auth key to derive a key specific for that website, uses that key to sign the challenge and then sends both the public key specific for that for that website plus the signed challenge to the specified URL.

When the service receives the public key it checks it against the challenge signature and start a session for that user. The user is then identified only by its public key. If the service wants it can, of course, request more details from the user, associate it with an internal id or username, it is free to do anything. lnurl-auth's goals end here: no passwords, maximum possible privacy.

FAQ

• What is the advantage of tying this to Bitcoin and Lightning?

  One big advantage is that your wallet is already keeping track of one seed, it is already a precious thing. If you had to keep track of a separate auth seed it would be arguably worse, more difficult to bootstrap the protocol, and arguably one of the reasons similar protocols, past and present, weren't successful.

• Just signing in to websites? What else is this good for?

  No, it can be used for authenticating to installable apps and physical places, as long as there is a service running an HTTP server somewhere to read the signature sent from the wallet. But yes, signing in to websites is the main problem to solve here.

• Phishing attack! Can a malicious website proxy the QR from a third website and show it to the user to it will steal the signature and be able to login on the third website?

  No, because the wallet will only talk to the the callback URL, and it will either be controlled by the third website, so the malicious won't see anything; or it will have a different domain, so the wallet will derive a different key and frustrate the malicious website's plan.

• I heard SQRL had that same idea and it went nowhere.

  Indeed. SQRL in its first version was basically the same thing as lnurl-auth, with one big difference: it was vulnerable to phishing attacks (see above). That was basically the only criticism it got everywhere, so the protocol creators decided to solve that by introducing complexity to the protocol. While they were at it they decided to add more complexity for managing accounts and so many more crap that in the the spec which initially was a single page ended up becoming 136 pages of highly technical gibberish. Then all the initial network effect it had, libraries and apps were trashed and nowadays no one can do anything with it (but, see, there are still people who love the protocol writing in a 90's forum with no clue of anything besides their own Java).

• We don't need this, we need WebAuthn!

  WebAuthn is essentially the same thing as lnurl-auth, but instead of being simple it is complex, instead of being open and decentralized it is centralized in big corporations, and instead of relying on a key generated by your own device it requires an expensive hardware HSM you must buy and trust the manufacturer. If you like WebAuthn and you like Bitcoin you should like lnurl-auth much more.

• What about BitID?

  This is another one that is very similar to lnurl-auth, but without the anti-phishing prevention and extra privacy given by making one different key for each service.

• What about LSAT?

  It doesn't compete with lnurl-auth. LSAT, as far as I understand it, is for when you're buying individual resources from a server, not authenticating as a user. Of course, LSAT can be repurposed as a general authentication tool, but then it will lack features that lnurl-auth has, like the property of having keys generated independently by the user from a common seed and a standard way of passing authentication info from one medium to another (like signing in to a website at the desktop from the mobile phone, for example).

When searching for a rental property, a thorough understanding of the rental agreement is essential. A well-crafted rental agreement protects both the tenant and the landlord, ensuring a clear and fair relationship. Here’s what you should look for in a rental agreement, particularly when considering options like property to rent in Wolverhampton, houses to rent in Codsall, or property to rent in Wombourne.

1. Rental Terms and Duration

The agreement should specify the rental period, whether it's a fixed-term lease or a month-to-month arrangement. For instance, if you’re looking at properties such as houses to rent Codsall, ensure the lease term aligns with your needs. Fixed-term leases provide stability, while month-to-month agreements offer flexibility but may have a higher rent or require more notice to terminate.

1. Rent and Payment Details

Verify the property to rent in Wombourne & rental amount and the due date. The agreement should outline the rent payment process, including acceptable payment methods. For properties like those in Wombourne, check if there are any additional fees, such as utilities or maintenance charges, and confirm how these will be handled.

1. Security Deposit

The agreement should clearly state the amount of the security deposit required, conditions for its return, and any deductions that may be made. For properties to rent in Wolverhampton, ensure that the deposit complies with local regulations and is held in a government-approved tenancy deposit scheme.

1. Maintenance and Repairs

Understand who is responsible for maintaining and repairing various aspects of the property. The agreement should outline the landlord’s obligations and the process for requesting repairs. This is crucial to avoid disputes over maintenance responsibilities, especially when renting houses to rent in Codsall.

1. Rules and Regulations

Review any specific rules about the property, such as restrictions on pets, smoking, or modifications. Ensure that these rules are reasonable and clearly defined in the rental agreement. For properties like those in Wombourne, it's important to know if there are any neighborhood rules or homeowner association guidelines that you need to follow.

1. Termination and Renewal Conditions

The agreement should detail the conditions for terminating the lease early, renewing the lease, or increasing the rent. Knowing these terms in advance can help you plan for any changes in your rental situation. This is particularly useful for rental properties in Wolverhampton, where lease terms may vary.

1. Legal and Contact Information

Ensure the agreement includes the landlord’s full contact information and any legal obligations you might have. It should also outline the procedure for resolving disputes. Clear communication channels are vital for smooth interactions throughout your tenancy.

A Causa

o Princípios de Economia Política de Menger é o único livro que enfatiza a CAUSA o tempo todo. os cientistas todos parecem não saber, ou se esquecer sempre, que as coisas têm causa, e que o conhecimento verdadeiro é o conhecimento da causa das coisas.

a causa é uma categoria metafísica muito superior a qualquer correlação ou resultado de teste de hipótese, ela não pode ser descoberta por nenhum artifício econométrico ou reduzida à simples antecedência temporal estatística. a causa dos fenômenos não pode ser provada cientificamente, mas pode ser conhecida.

o livro de Menger conta para o leitor as causas de vários fenômenos econômicos e as interliga de forma que o mundo caótico da economia parece adquirir uma ordem no momento em que você lê. é uma sensação mágica e indescritível.

quando eu te o recomendei, queria é te imbuir com o espírito da busca pela causa das coisas. depois de ler aquilo, você está apto a perceber continuidade causal nos fenômenos mais complexos da economia atual, enxergar as causas entre toda a ação governamental e as suas várias consequências na vida humana. eu faço isso todos os dias e é a melhor sensação do mundo quando o caos das notícias do caderno de Economia do jornal -- que para o próprio jornalista que as escreveu não têm nenhum sentido (tanto é que ele escreve tudo errado) -- se incluem num sistema ordenado de causas e consequências.

provavelmente eu sempre erro em alguns ou vários pontos, mas ainda assim é maravilhoso. ou então é mais maravilhoso ainda quando eu descubro o erro e reinsiro o acerto naquela racionalização bela da ordem do mundo econômico que é a ordem de Deus.

A biblioteca infinita

Agora esqueci o nome do conto de Jorge Luis Borges em que a tal biblioteca é descrita, ou seus detalhes específicos. Eu tinha lido o conto e nunca havia percebido que ele matava a questão da aleatoriedade ser capaz de produzir coisas valiosas. Precisei mesmo da Wikipédia me dizer isso.

Alguns anos atrás levantei essa questão para um grupo de amigos sem saber que era uma questão tão batida e baixa. No meu exemplo era um cachorro andando sobre letras desenhadas e não um macaco numa máquina de escrever. A minha conclusão da discussão foi que não importa o que o cachorro escrevesse, sem uma inteligência capaz de compreender aquilo nada passaria de letras aleatórias.

Borges resolve tudo imaginando uma biblioteca que contém tudo o que o cachorro havia escrito durante todo o infinito em que fez o experimento, e portanto contém todo o conhecimento sobre tudo e todas as obras literárias possíveis -- mas entre cada página ou frase muito boa ou pelo menos legívei há toneladas de livros completamente aleatórios e uma pessoa pode passar a vida dentro dessa biblioteca que contém tanto conhecimento importante e mesmo assim não aprender nada porque nunca vai achar os livros certos.

Everything would be in its blind volumes. Everything: the detailed history of the future, Aeschylus' The Egyptians, the exact number of times that the waters of the Ganges have reflected the flight of a falcon, the secret and true nature of Rome, the encyclopedia Novalis would have constructed, my dreams and half-dreams at dawn on August 14, 1934, the proof of Pierre Fermat's theorem, the unwritten chapters of Edwin Drood, those same chapters translated into the language spoken by the Garamantes, the paradoxes Berkeley invented concerning Time but didn't publish, Urizen's books of iron, the premature epiphanies of Stephen Dedalus, which would be meaningless before a cycle of a thousand years, the Gnostic Gospel of Basilides, the song the sirens sang, the complete catalog of the Library, the proof of the inaccuracy of that catalog. Everything: but for every sensible line or accurate fact there would be millions of meaningless cacophonies, verbal farragoes, and babblings. Everything: but all the generations of mankind could pass before the dizzying shelves – shelves that obliterate the day and on which chaos lies – ever reward them with a tolerable page.

Tenho a impressão de que a publicação gigantesca de artigos, posts, livros e tudo o mais está transformando o mundo nessa biblioteca. Há tanta coisa pra ler que é difícil achar o que presta. As pessoas precisam parar de escrever.

IPFS problems: Shitcoinery

IPFS was advertised to the Ethereum community since the beggining as a way to "store" data for their "dApps". I don't think this is harmful in any way, but for some reason it may have led IPFS developers to focus too much on Ethereum stuff. Once I watched a talk showing libp2p developers – despite being ignored by the Ethereum team (that ended up creating their own agnostic p2p library) – dedicating an enourmous amount of work on getting a libp2p app running in the browser talking to a normal Ethereum node.

The always somewhat-abandoned "Awesome IPFS" site is a big repository of "dApps", some of which don't even have their landing page up anymore, useless Ethereum smart contracts that for some reason use IPFS to store whatever the useless data their users produce.

Again, per se it isn't a problem that Ethereum people are using IPFS, but it is at least confusing, maybe misleading, that when you search for IPFS most of the use-cases are actually Ethereum useless-cases.

Why IPFS cannot work, again

Imagine someone comes up with a solution for P2P content-addressed data-sharing that involves storing all the files' contents in all computers of the network. That wouldn't work, right? Too much data, if you think this can work then you're a BSV enthusiast.

Then someone comes up with the idea of not storing everything in all computers, but only some things on some computers, based on some algorithm to determine what data a node would store given its pubkey or something like that. Still wouldn't work, right? Still too much data no matter how much you spread it, but mostly incentives not aligned, would implode in the first day.

Now imagine someone says they will do the same thing, but instead of storing the full contents each node would only store a pointer to where each data is actually available. Does that make it better? Hardly so. Still, you're just moving the problem.

This is IPFS.

Now you have less data on each computer, but on a global scale that is still a lot of data.

No incentives.

And now you have the problem of finding the data. First if you have some data you want the world to access you have to broadcast information about that, flooding the network -- and everybody has to keep doing this continuously for every single file (or shard of file) that is available.

And then whenever someone wants some data they must find the people who know about that, which means they will flood the network with requests that get passed from peer to peer until they get to the correct peer.

The more you force each peer to store the worse it becomes to run a node and to store data on behalf of others -- but the less your force each peer to store the more flooding you'll have on the global network, and the slower will be for anyone to actually get any file.

---

But if everybody just saves everything to Infura or Cloudflare then it works, magic decentralized technology.

Who will build the roads?

Who will build the roads? Em Lagoa Santa, as mais novas e melhores ruas -- que na verdade acabam por formar enormes teias de bairros que se interligam -- são construídas pelos loteadores que querem as ruas para que seus lotes valham mais -- e querem que outras pessoas usem as ruas também. Também são esses mesmos loteadores que colocam os postes de luz e os encanamentos de água, não sem antes terem que se submeter a extorsões de praxe praticadas por COPASA e CEMIG.

Se ao abrir um loteamento, condomínio, prédio um indivíduo ou uma empresa consegue sem muito problema passar rua, eletricidade, água e esgoto, por que não seria possível existir livre-concorrência nesses mercados? Mesmo aquela velha estória de que é ineficiente passar cabos de luz duplicados para que companhias elétricas possam competir já me parece bobagem.

How IPFS is broken

I once fell for this talk about "content-addressing". It sounds very nice. You know a certain file exists, you know there are probably people who have it, but you don't know where or if it is hosted on a domain somewhere. With content-addressing you can just say "start" and the download will start. You don't have to care.

Other magic properties that address common frustrations: webpages don't go offline, links don't break, valuable content always finds its way, other people will distribute your website for you, any content can be transmitted easily to people near you without anyone having to rely on third-party centralized servers.

But you know what? Saying a thing is good doesn't automatically make it possible and working. For example: saying stuff is addressed by their content doesn't change the fact that the internet is "location-addressed" and you still have to know where peers that have the data you want are and connect to them.

And what is the solution for that? A DHT!

DHT?

Turns out DHTs have terrible incentive structure (as you would expect, no one wants to hold and serve data they don't care about to others for free) and the IPFS experience proves it doesn't work even in a small network like the IPFS of today.

If you have run an IPFS client you'll notice how much it clogs your computer. Or maybe you don't, if you are very rich and have a really powerful computer, but still, it's not something suitable to be run on the entire world, and on web pages, and servers, and mobile devices. I imagine there may be a lot of unoptimized code and technical debt responsible for these and other problems, but the DHT is certainly the biggest part of it. IPFS can open up to 1000 connections by default and suck up all your bandwidth -- and that's just for exchanging keys with other DHT peers.

Even if you're in the "client" mode and limit your connections you'll still get overwhelmed by connections that do stuff I don't understand -- and it makes no sense to run an IPFS node as a client, that defeats the entire purpose of making every person host files they have and content-addressability in general, centralizes the network and brings back the dichotomy client/server that IPFS was created to replace.

Connections?

So, DHTs are a fatal flaw for a network that plans to be big and interplanetary. But that's not the only problem.

Finding content on IPFS is the most slow experience ever and for some reason I don't understand downloading is even slower. Even if you are in the same LAN of another machine that has the content you need it will still take hours to download some small file you would do in seconds with scp -- that's considering that IPFS managed to find the other machine, otherwise your command will just be stuck for days.

Now even if you ignore that IPFS objects should be content-addressable and not location-addressable and, knowing which peer has the content you want, you go there and explicitly tell IPFS to connect to the peer directly, maybe you can get some seconds of (slow) download, but then IPFS will drop the connection and the download will stop. Sometimes -- but not always -- it helps to add the peer address to your bootstrap nodes list (but notice this isn't something you should be doing at all).

IPFS Apps?

Now consider the kind of marketing IPFS does: it tells people to build "apps" on IPFS. It sponsors "databases" on top of IPFS. It basically advertises itself as a place where developers can just connect their apps to and all users will automatically be connected to each other, data will be saved somewhere between them all and immediately available, everything will work in a peer-to-peer manner.

Except it doesn't work that way at all. "libp2p", the IPFS library for connecting people, is broken and is rewritten every 6 months, but they keep their beautiful landing pages that say everything works magically and you can just plug it in. I'm not saying they should have everything perfect, but at least they should be honest about what they truly have in place.

It's impossible to connect to other people, after years there's no js-ipfs and go-ipfs interoperability (and yet they advertise there will be python-ipfs, haskell-ipfs, whoknowswhat-ipfs), connections get dropped and many other problems.

So basically all IPFS "apps" out there are just apps that want to connect two peers but can't do it manually because browsers and the IPv4/NAT network don't provide easy ways to do it and WebRTC is hard and requires servers. They have nothing to do with "content-addressing" anything, they are not trying to build "a forest of merkle trees" nor to distribute or archive content so it can be accessed by all. I don't understand why IPFS has changed its core message to this "full-stack p2p network" thing instead of the basic content-addressable idea.

IPNS?

And what about the database stuff? How can you "content-address" a database with values that are supposed to change? Their approach is to just save all values, past and present, and then use new DHT entries to communicate what are the newest value. This is the IPNS thing.

Apparently just after coming up with the idea of content-addressability IPFS folks realized this would never be able to replace the normal internet as no one would even know what kinds of content existed or when some content was updated -- and they didn't want to coexist with the normal internet, they wanted to replace it all because this message is more bold and gets more funding, maybe?

So they invented IPNS, the name system that introduces location-addressability back into the system that was supposed to be only content-addressable.

And how do they manage to do it? Again, DHTs. And does it work? Not really. It's limited, slow, much slower than normal content-addressing fetches, most of the times it doesn't even work after hours. But still although developers will tell it is not working yet the IPFS marketing will talk about it as if it was a thing.

Archiving content?

The main use case I had for IPFS was to store content that I personally cared about and that other people might care too, like old articles from dead websites, and videos, sometimes entire websites before they're taken down.

So I did that. Over many months I've archived stuff on IPFS. The IPFS API and CLI don't make it easy to track where stuff are. The pin command doesn't help as it just throws your pinned hash in a sea of hashes and subhashes and you're never able to find again what you have pinned.

The IPFS daemon has a fake filesystem that is half-baked in functionality but allows you to locally address things by names in a tree structure. Very hard to update or add new things to it, but still doable. It allows you to give names to hashes, basically. I even began to write a wrapper for it, but suddenly after many weeks of careful content curation and distribution all my entries in the fake filesystem were gone.

Despite not having lost any of the files I did lose everything, as I couldn't find them in the sea of hashes I had in my own computer. After some digging and help from IPFS developers I managed to recover a part of it, but it involved hacks. My things vanished because of a bug at the fake filesystem. The bug was fixed, but soon after I experienced a similar (new) bug. After that I even tried to build a service for hash archival and discovery, but as all the problems listed above began to pile up I eventually gave up. There were also problems of content canonicalization, the code the IPFS daemon use to serve default HTML content over HTTP, problems with the IPFS browser extension and others.

Future-proof?

One of the core advertised features of IPFS was that it made content future-proof. I'm not sure they used this expression, but basically you have content, you hash that, you get an address that never expires for that content, now everybody can refer to the same thing by the same name. Actually, it's better: content is split and hashed in a merkle-tree, so there's fine-grained deduplication, people can store only chunks of files and when a file is to be downloaded lots of people can serve it at the same time, like torrents.

But then come the protocol upgrades. IPFS has used different kinds of hashing algorithms, different ways to format the hashes, and will change the default algorithm for building the merkle-trees, so basically the same content now has a gigantic number of possible names/addresses, which defeats the entire purpose, and yes, files hashed using different strategies aren't automagically compatible.

Actually, the merkle algorithm could have been changed by each person on a file-by-file basis since the beginning (you could for example split a book file by chapter or page instead of by chunks of bytes) -- although probably no one ever did that. I know it's not easy to come up with the perfect hashing strategy in the first go, but the way these matters are being approached make me wonder that IPFS promoters aren't really worried about future-proof, or maybe we're just in Beta phase forever.

Ethereum?

This is also a big problem. IPFS is built by Ethereum enthusiasts. I can't read the mind of people behind IPFS, but I would imagine they have a poor understanding of incentives like the Ethereum people, and they tend towards scammer-like behavior like getting a ton of funds for investors in exchange for promises they don't know they can fulfill (like Filecoin and IPFS itself) based on half-truths, changing stuff in the middle of the road because some top-managers decided they wanted to change (move fast and break things) and squatting fancy names like "distributed web".

The way they market IPFS (which is not the main thing IPFS was initially designed to do) as a "peer-to-peer cloud" is very seductive for Ethereum developers just like Ethereum itself is: as a place somewhere that will run your code for you so you don't have to host a server or have any responsibility, and then Infura will serve the content to everybody. In the same vein, Infura is also hosting and serving IPFS content for Ethereum developers these days for free. Ironically, just like the Ethereum hoax peer-to-peer money, IPFS peer-to-peer network may begin to work better for end users as things get more and more centralized.

Lagoa Santa: como chegar -- partindo da rodoviária de Belo Horizonte

Ao descer de seu ônibus na rodoviária de Belo Horizonte às 4 e pouco da manhã, darás de frente para um caubói que toma cerveja em seus trajes típicos em um bar no setor mesmo de desembarque. Suba a escada à direita que dá no estacionamento da rodoviária. Vire à esquerda e caminhe por mais ou menos 400 metros, atravessando uma área onde pessoas suspeitas -- mas provavelmente dormindo em pé -- lhe observam, e então uma pracinha ocupada por um clã de mendigos. Ao avistar um enorme obelisco no meio de um cruzamento de duas avenidas, vire à esquerda e caminhe por mais 400 metros. Você verá uma enorme, antiga e bela estação com uma praça em frente, com belas fontes aqüáticas. Corra dali e dirija-se a um pedaço de rua à direita dessa praça. Um velho palco de antigos carnavais estará colocado mais ou menos no meio da simpática ruazinha de parelepípedos: é onde você pegará seu próximo ônibus.

Para entrar na estação é necessário ter um cartão com créditos recarregáveis. Um viajante prudente deixa sempre um pouco de créditos em seu cartão a fim de evitar filas e outros problemas de indisponibilidade quando chega cansado de viagem, com pressa ou em horários incomuns. Esse tipo de pessoa perceberá que foi totalmente ludibriado ao perceber que que os créditos do seu cartão, abastecido quando de sua última vinda a Belo Horizonte, há três meses, pereceram de prazo de validade e foram absorvidos pelos cofre públicos. Terá, portanto, que comprar mais créditos. O guichê onde os cartões são abastecidos abre às 5h, mas não se espante caso ele não tenha sido aberto ainda quando o primeiro ônibus chegar, às 5h10.

Com alguma sorte, um jovem de moletom, autorizado por dois ou três fiscais do sistema de ônibus que conversam alegremente, será o operador da catraca. Ele deixa entrar sem pagar os bêbados, os malandros, os pivetes. Bastante empático e perceptivo do desespero dos outros, esse bom rapaz provavelmente também lhe deixará entrar sem pagar.

Uma vez dentro do ônibus, não se intimide com os gritalhões e valentões que, ofendidíssimos com o motorista por ele ter parado nas estações, depois dos ônibus anteriores terem ignorado esses excelsos passageiros que nelas aguardavam, vão aos berros tirar satisfação.

O ponto final do ônibus, 40 minutos depois, é o terminal Morro Alto. Lá você verá, se procurar bem entre vários ônibus e pessoas que despertam a sua mais honesta suspeita, um veículo escuro, apagado, numerado 5882 e que abrigará em seu interior um motorista e um cobrador que descansam o sono dos justos.

Aguarde na porta por mais uns vinte minutos até que, repentinamente desperto, o motorista ligue o ônibus, abra as portas e já comece, de leve, a arrancar. Entre correndo, mas espere mais um tempo, enquanto as pessoas que têm o cartão carregado passem e peguem os melhores lugares, até que o cobrador acorde e resolva te cobrar a passagem nesse velho meio de pagamento, outrora o mais líqüído, o dinheiro.

Este último ônibus deverá levar-lhe, enfim, a Lagoa Santa.

Jofer

Jofer era um jogador diferente. À primeira vista não, parecia igual, um volante combativo, perseguia os atacantes adversários implacavelmente, um bom jogador. Mas não era essa a característica que diferenciava Jofer. Jofer era, digamos, um chutador.

Começou numa semifinal de um torneio de juniores. O time de Jofer precisava do empate e estava sofrendo uma baita pressão do adversário, mas o jogo estava 1 a 1 e parecia que ia ficar assim mesmo, daquele jeito futebolístico que parece, parece mesmo. Só que aos 46 do segundo tempo tomaram um gol espírita, Ruizinho do outro time saiu correndo pela esquerda e, mesmo sendo canhoto, foi cortando para o meio, os zagueiros meio que achando que já tinha acabado mesmo, devia ter só mais aquele lance, o árbitro tinha dado dois minutos, Ruizinho chutou, marcou e o goleiro, que só pulou depois que já tinha visto que não ia ter jeito, ficou xingando.

A bola saiu do meio e tocaram para Jofer, ninguém nem veio marcá-lo, o outro time já estava comemorando, e com razão, o juiz estava de sacanagem em fazer o jogo continuar, já estava tudo acabado mesmo. Mas não, estava certo, mais um minuto de acréscimo, justo. Em um minuto dá pra fazer um gol. Mas como? Jofer pensou nas partidas da NBA em que com alguns centésimos de segundo faltando o armador jogava de qualquer jeito para a cesta e às vezes acertava. De trás do meio de campo, será? Não vou ter nem força pra fazer chegar no gol. Vou virar piada, melhor tocar pro Fumaça ali do lado e a gente perde sem essa humilhação no final. Mas, poxa, e daí? Vou tentar mesmo assim, qualquer coisa eu falo que foi um lançamento e daqui a uns dias todo mundo esquece. Olhou para o próprio pé, virou ele de ladinho, pra fora e depois pra dentro (bom, se eu pegar daqui, direitinho, quem sabe?), jogou a bola pro lado e bateu. A bola subiu escandalosamente, muito alta mesmo, deve ter subido uns 200 metros. Jofer não tinha como ter a menor noção. Depois foi descendo, o goleirão voltando correndo para debaixo da trave e olhando pra bola, foi chegando e pulando já só pra acompanhar, para ver, dependurado no travessão, a bola sair ainda bem alta, ela bateu na rede lateral interna antes de bater no chão, quicar violentamente e estufar a rede no alto do lado direito de quem olhava.

Mas isso tudo foi sonho do Jofer. Sonhou acordado, numa noite em que demorou pra dormir, deitado na sua cama. Ficou pensando se não seria fácil, se ele treinasse bastante, acertar o gol bem de longe, tipo no sonho, e se não dava pra fazer gol assim. No dia seguinte perguntou a Brunildinho, o treinador de goleiros. Era difícil defender essas bolas, ainda mais se elas subissem muito, o goleiro ficava sem perspectiva, o vento alterava a trajetória a cada instante, tinha efeito, ela cairia rápido, mas claro que não valia à pena treinar isso, a chance de acertar o gol era minúscula. Mas Jofer só ia tentar depois que treinasse bastante e comprovasse o que na sua imaginação parecia uma excelente idéia.

Começou a treinar todos os dias. Primeiro escondido, por vergonha dos colegas, chegava um pouco antes e ficava lá, chutando do círculo central. Ao menor sinal de gente se aproximando, parava e ia catar as bolas. Depois, quando começou a acertar, perdeu a vergonha. O pessoal do clube todo achava engraçado quando via Jofer treinando e depois ouvia a explicação da boca de alguém, ninguém levava muito a sério, mas também não achava de todo ridículo. O pessoal ria, mas no fundo torcia praquilo dar certo, mesmo.

Aconteceu que num jogo que não valia muita coisa, empatezinho feio, aos 40 do segundo tempo, a marcação dos adversários já não estava mais pressionando, todo mundo contente com o empate e com vontade de parar de jogar já, o Henrique, meia-esquerdo, humilde, mas ainda assim um pouco intimidante para Jofer (jogava demais), tocou pra ele. Vai lá, tenta sua loucura aí. Assumiu a responsabilidade do nosso volante introspectivo. Seria mais verossímil se Jofer tivesse errado, primeira vez que tentou, restava muito tempo ainda pra ele ter a chance de ser herói, ninguém acerta de primeira, mas ele acertou. Quase como no sonho, Lucas, o goleiro, não esperava, depois que viu o lance, riu-se, adiantou-se para pegar a bola que ele julgava que quicaria na área, mas ela foi mais pra frente, mais e mais, daí Lucas já estava correndo, só que começou a pensar que ela ia pra fora, e ele ia só se dependurar no travessão e fazer seu papel de estar na bola. Acabou que por conta daquele gol eles terminaram em segundo no grupo daquele torneiozinho, ao invés de terceiro, e não fez diferença nenhuma.

Parallel Chains

We want merged-mined blockchains. We want them because it is possible to do things in them that aren't doable in the normal Bitcoin blockchain because it is rightfully too expensive, but there are other things beside the world money that could benefit from a "distributed ledger" -- just like people believed in 2013 --, like issued assets and domain names (just the most obvious examples).

On the other hand we can't have -- like people believed in 2013 -- a copy of Bitcoin for every little idea with its own native token that is mined by proof-of-work and must get off the ground from being completely valueless into having some value by way of a miracle that operated only once with Bitcoin.

It's also not a good idea to have blockchains with custom merged-mining protocol (like Namecoin and Rootstock) that require Bitcoin miners to run their software and be an active participant and miner for that other network besides Bitcoin, because it's too cumbersome for everybody.

Luckily Ruben Somsen invented this protocol for blind merged-mining that solves the issue above. Although it doesn't solve the fact that each parallel chain still needs some form of "native" token to pay miners -- or it must use another method that doesn't use a native token, such as trusted payments outside the chain.

How does it work

With the SIGHASH_NOINPUT/SIGHASH_ANYPREVOUT soft-fork[^eltoo] it becomes possible to create presigned transactions that aren't related to any previous UTXO.

Then you create a long sequence of transactions (sufficient to last for many many years), each with an nLockTime of 1 and each spending the next (you create them from the last to the first). Since their scriptSig (the unlocking script) will use SIGHASH_ANYPREVOUT you can obtain a transaction id/hash that doesn't include the previous TXO, you can, for example, in a sequence of transactions A0-->B (B spends output 0 from A), include the signature for "spending A0 on B" inside the scriptPubKey (the locking script) of "A0".

With the contraption described above it is possible to make that long string of transactions everybody will know (and know how to generate) but each transaction can only be spent by the next previously decided transaction, no matter what anyone does, and there always must be at least one block of difference between them.

Then you combine it with RBF, SIGHASH_SINGLE and SIGHASH_ANYONECANPAY so parallel chain miners can add inputs and outputs to be able to compete on fees by including their own outputs and getting change back while at the same time writing a hash of the parallel block in the change output and you get everything working perfectly: everybody trying to spend the same output from the long string, each with a different parallel block hash, only the highest bidder will get the transaction included on the Bitcoin chain and thus only one parallel block will be mined.

• Step 1: Education

• Step 2: Accessibility

• Step 3: Regulation

• Conclusion

• FAQ

Bitcoin has been on the rise in recent years as a viable alternative to traditional forms of payment. Despite its growing popularity, there are still many barriers to its widespread adoption. To break down these barriers and accelerate Bitcoin adoption, a three-step plan must be implemented. This plan includes education, accessibility, and regulation. Through education, people will gain a better understanding of the benefits of Bitcoin. Accessibility will make it easier for people to buy, sell, and use Bitcoin, while regulation will provide guidelines and protect consumers. In this article, we will explore these three steps in detail and how they can be implemented to increase the adoption of Bitcoin.

Step 1: Education

The first step in accelerating Bitcoin adoption is education. Many people still don't understand what Bitcoin is, how it works, or why it's important. It's essential to educate people about the benefits of Bitcoin, such as its decentralized nature, low transaction fees, and fast processing times. Bitcoin's transparency and security features also make it an attractive option for those concerned with privacy and fraud prevention.

Educating people about Bitcoin can be done through a variety of channels, including social media, podcasts, online courses, and events. Governments, businesses, and financial institutions should also play a role in educating the public about Bitcoin. This can be done by providing accurate information about Bitcoin and its potential uses and benefits.

Step 2: Accessibility

The second step in accelerating Bitcoin adoption is accessibility. Many people still find it challenging to buy, sell, and use Bitcoin. This is due in part to the lack of infrastructure and the complicated nature of Bitcoin transactions. To increase accessibility, businesses and financial institutions should make it easier for people to buy, sell, and use Bitcoin.

One way to do this is to create more user-friendly Bitcoin wallets and exchanges. These platforms should be designed to be intuitive and easy to use, even for people with little to no experience with Bitcoin. Financial institutions should also consider offering Bitcoin services to their customers, such as the ability to buy, sell, and hold Bitcoin within their accounts.

Step 3: Regulation

The third and final step in accelerating Bitcoin adoption is regulation. While Bitcoin's decentralized nature is one of its most significant benefits, it has also created challenges in terms of regulation. Governments and financial regulators are still trying to figure out how to regulate Bitcoin effectively.

To accelerate Bitcoin adoption, governments should work to create clear and consistent regulations around Bitcoin. These regulations should provide guidelines for businesses and individuals using Bitcoin while also protecting consumers from fraud and other risks associated with Bitcoin transactions. Regulations should be designed to encourage innovation and investment in the Bitcoin ecosystem while also ensuring that it remains a safe and reliable form of payment.

Conclusion

Bitcoin has the potential to revolutionize the way we think about money and payment systems. However, for this potential to be realized, we need to break down the barriers that are preventing its widespread adoption. By following this three-step plan of education, accessibility, and regulation, we can accelerate Bitcoin adoption and bring the benefits of this groundbreaking technology to people around the world.

FAQ

Why is education important for Bitcoin adoption? Education is important for Bitcoin adoption because many people still don't understand what Bitcoin is or how it works. Educating people about Bitcoin's benefits and potential uses can increase its adoption.

How can businesses and financial institutions increase accessibility to Bitcoin? Businesses and financial institutions can increase accessibility to Bitcoin by creating more user-friendly Bitcoin wallets and exchanges. They can also offer Bitcoin services to their customers, such as the ability to buy, sell, and hold Bitcoin within their accounts.

What are some of the challenges of regulating Bitcoin? One of the biggest challenges of regulating Bitcoin is its decentralized nature. Bitcoin operates on a peer-to-peer network without a central authority, making it difficult to regulate. Additionally, regulations must strike a balance between protecting consumers and encouraging innovation and investment in the Bitcoin ecosystem.

What are some examples of countries that have embraced Bitcoin? Some countries that have embraced Bitcoin include Japan, Switzerland, and Malta. These countries have established regulations around the use of Bitcoin and have created a welcoming environment for cryptocurrency startups and businesses.

OP_CHECKTEMPLATEVERIFY and the "covenants" drama

There are many ideas for "covenants" (I don't think this concept helps in the specific case of examining proposals, but fine). Some people think "we" (it's not obvious who is included in this group) should somehow examine them and come up with the perfect synthesis.

It is not clear what form this magic gathering of ideas will take and who (or which ideas) will be allowed to speak, but suppose it happens and there is intense research and conversations and people (ideas) really enjoy themselves in the process.

What are we left with at the end? Someone has to actually commit the time and put the effort and come up with a concrete proposal to be implemented on Bitcoin, and whatever the result is it will have trade-offs. Some great features will not make into this proposal, others will make in a worsened form, and some will be contemplated very nicely, there will be some extra costs related to maintenance or code complexity that will have to be taken. Someone, a concreate person, will decide upon these things using their own personal preferences and biases, and many people will not be pleased with their choices.

That has already happened. Jeremy Rubin has already conjured all the covenant ideas in a magic gathering that lasted more than 3 years and came up with a synthesis that has the best trade-offs he could find. CTV is the result of that operation.

---

The fate of CTV in the popular opinion illustrated by the thoughtless responses it has evoked such as "can we do better?" and "we need more review and research and more consideration of other ideas for covenants" is a preview of what would probably happen if these suggestions were followed again and someone spent the next 3 years again considering ideas, talking to other researchers and came up with a new synthesis. Again, that person would be faced with "can we do better?" responses from people that were not happy enough with the choices.

And unless some famous Bitcoin Core or retired Bitcoin Core developers were personally attracted by this synthesis then they would take some time to review and give their blessing to this new synthesis.

To summarize the argument of this article, the actual question in the current CTV drama is that there exists hidden criteria for proposals to be accepted by the general community into Bitcoin, and no one has these criteria clear in their minds. It is not as simple not as straightforward as "do research" nor it is as humanly impossible as "get consensus", it has a much bigger social element into it, but I also do not know what is the exact form of these hidden criteria.

This is said not to blame anyone -- except the ignorant people who are not aware of the existence of these things and just keep repeating completely false and unhelpful advice for Jeremy Rubin and are not self-conscious enough to ever realize what they're doing.

Comprimido desodorante

No episódio sei-lá-qual de Aleixo FM Bruno Aleixo diz que os bêbados sempre têm as melhores idéias e daí conta uma idéia que ele teve quando estava bêbado: um comprimido que funciona como desodorante. Ao invés de passar o desodorante spray ou roll-on a pessoa pode só tomar o comprimido e pronto, é muito mais prático e no tempo de frio a pessoa pode vestir a roupa mais rápido, sem precisar ficar passando nada com o tronco todo nu. Quando o Busto lhe pergunta sobre a possibilidade de algo assim ser fabricado ele diz que não sabe, que não é cientista, só tem as idéias.

Essa passagem tão boba de um programa de humor esconde uma verdade sobre a doutrina cientística que permeia a sociedade. A doutrina segundo a qual é da ciência que vêm as inovações tecnológicas e de todos os tipos, e por isso é preciso que o Estado tire dinheiro das pessoas trabalhadoras e dê para os cientistas. Nesse ponto ninguém mais sabe o que é um cientista, foi-se toda a concretude, ficou só o nome: "cientista". Daí vão procurar o tal cientista, é um cara que se formou numa universidade e está fazendo um mestrado. Pronto, é só dar dinheiro pra esse cara e tudo vai ficar bom.

Tirando o problema da desconexão entre realidade e a tese, existe também, é claro, o problema da tese: não faz sentido, que um cientista fique procurando formas de realizar uma idéia, que não se sabe nem se é possível nem se é desejável, que ele ou outra pessoa tiveram, muito pelo contrário (mas não vou dizer aqui o que é que era para o cientista fazer porque isso seria contraditório e eu não acho que devam nem existir cientistas).

O que eu queria dizer mesmo era: todo o aparato científico da nossa sociedade, todos os departamentos, universidades, orçamentos e bolsas e revistas, tudo se resume a um monte de gente tentando descobrir como fazer um comprimido desodorante.

Flowi.es

At the time I thought Workflowy had the ideal UI for everything. I wanted to implement my custom app maker on it, but ended up doing this: a platform for enhancing Workflowy with extra features:

• An email reminder based on dates input in items
• A website generator, similar to Websites For Trello, also based on Classless Templates

Also, I didn't remember this was also based on CouchDB and had some couchapp functionalities.

On the state of programs and browsers

Basically, there are basically (not exhaustively) 2 kinds of programs one can run in a computer nowadays:

1.1. A program that is installed, permanent, has direct access to the Operating System, can draw whatever it wants, modify files, interact with other programs and so on; 1.2. A program that is transient, fetched from someone else's server at run time, interpreted, rendered and executed by another program that bridges the access of that transient program to the OS and other things.

Meanwhile, web browsers have basically (not exhaustively) two use cases:

2.1. Display text, pictures, videos hosted on someone else's computer; 2.2. Execute incredibly complex programs that are fetched at run time, executed and so on -- you get it, it's the same 1.2.

These two use cases for browsers are at big odds with one another. While stretching itsel f to become more and more a platform for programs that can do basically anything (in the 1.1 sense) they are still restricted to being an 1.2 platform. At the same time, websites that were supposed to be on 2.1 sometimes get confused and start acting as if they were 2.2 -- and other confusing mixed up stuff.

I could go hours in philosophical inquiries on the nature of browsers, how rewriting everything in JavaScript is not healthy or where everything went wrong, but I think other people have done this already.

One thing that bothers me a lot, though, is that computers can do a lot of things, and with the internet and in the current state of the technology it's fairly easy to implement tools that would help in many aspects of human existence and provide high-quality, useful programs, with the help of a server to coordinate access, store data, authenticate users and so on many things are possible. However, due to the nature of UI in the browser, it's very hard to get any useful tool to users.

Writing a UI, even the most basic UI imaginable (some text input boxes and some buttons, or a table) can take a long time, always more than the time necessary to code the actual core features of whatever program is being developed -- and that is considering that the person capable of writing interesting programs that do the functionality in the backend are also capable of interacting with JavaScript and the giant amount of frameworks, transpilers, styling stuff, CSS, the fact that all this is built on top of HTML and so on.

This is not good.

A big Ethereum problem that is fixed by Drivechain

While reading the following paragraphs, assume Drivechain itself will be a "smart contract platform", like Ethereum. And that it won't be used to launch an Ethereum blockchain copy, but instead each different Ethereum contract could be turned into a different sidechain under BIP300 rules.

A big Ethereum problem

Anyone can publish any "contract" to Ethereum. Often people will come up with somewhat interesting ideas and publish them. Since they want money they will add an unnecessary token and use that to bring revenue to themselves, gamify the usage of their contract somehow, and keep some control over the supposedly open protocol they've created by keeping a majority of the tokens. They will use the profits on marketing and branding, have a visual identity, a central website and a forum with support personnel and so on: their somewhat interesting idea have become a full-fledged company.

If they have success then another company will appear in the space and copy the idea, launch it using exactly the same strategy with a tweak, then try to capture the customers of the first company and new people. And then another, and another, and another. Very often these contracts require some network effect to work, i.e., they require people to be using it so others will use it. The fact that the market is now split into multiple companies offering roughly the same product hurts that, such that none of these protocols get ever enough usage to become really useful in the way they were first conceived. At this point it doesn't matter though, they get some usage, and they use that in their marketing material. It becomes a race to pump the value of the tokens and the current usage is just another point used for that purpose. The company will even start giving out money to attract new users and other weird moves that have no relationship with the initial somewhat intereting idea.

Once in a lifetime it happens that the first implementer of these things is not a company seeking profits, but some altruistic developer or company that believes in Ethereum and wants to see it grow -- or more likely someone financed by the Ethereum Foundation, which allegedly doesn't like these token schemes and would prefer everybody to use the token they issued first, the ETH --, but that's a fruitless enterprise because someone else will copy that idea anyway and turn it into a company as described above.

How Drivechain fixes it

In the Drivechain world, if someone had an idea, they would -- as it happens all the time with Bitcoin things -- publish it in a public forum. Other members of the community would evaluate that idea, add or remove things, all interested parties would contribute to make it the best possible incarnation of that idea. Once the design was settled, someone would volunteer to start writing the code to turn that idea into a sidechain. Maybe some company would fund those efforts and then more people would join. It's not a perfect process and one that often involves altruism, but Bitcoin inspires people to do these things.

Slowly, the thing would get built, tested, activated as a sidechain on testnet, tested more, and at this point luckily the entire community of interested Bitcoin users and miners would have grown to like that idea and see its benefits. It could then be proposed to be activated according to BIP300 rules.

Once it was activated, the entire pool of interested users would join it. And it would be impossible for someone else to create a copy of that because everybody would instantly notice it was a copy. There would be no token, no one profiting directly from the operations of that "smart contract". And everybody would be incentivized to join and tell others to join that same sidechain since the network effect was already the biggest there, they will know more network effect would only be good for everybody involved, and there would be no competing marketing and free token giveaways from competing entities.

لوگو پژو یکی از نمادهای شناخته‌شده در صنعت خودروسازی است که تاریخچه‌ای غنی و جذاب دارد. این برند فرانسوی که در سال ۱۸۱۰ تأسیس شد، ابتدا به تولید ابزار و سپس به ساخت خودرو روی آورد. لوگوی پژو در طول سال‌ها تغییرات زیادی را تجربه کرده است که هر یک به نوعی نمایانگر تحولات و پیشرفت‌های این برند است.

لوگوی فعلی پژو شامل تصویر یک شیر است که در حالت ایستاده و با قدرت نمایش داده شده است. شیر به عنوان نماد قدرت، شجاعت و سرسختی شناخته می‌شود و نشان‌دهنده روحیه‌ای است که پژو به محصولات خود می‌دهد. طراحی این شیر به گونه‌ای است که حس حرکت و پویایی را منتقل می‌کند، که با فلسفه تولید خودروهای با کیفیت و تکنولوژی پیشرفته پژو همخوانی دارد.

تاریخچه لوگوی پژو به سال ۱۸۴۷ برمی‌گردد، زمانی که این برند برای اولین بار از نماد شیر استفاده کرد. در آن زمان، لوگو شامل تصویر ساده‌تری از شیر بود که به تدریج با تغییرات طراحی به شکل کنونی خود نزدیک‌تر شد. در دهه‌های مختلف، این لوگو با تغییرات ظاهری و به‌روز رسانی‌های مدرن همراه بوده است، اما همواره هویت اصلی خود را حفظ کرده است.

لوگوی پژو نه تنها بر روی خودروهای این برند قرار دارد، بلکه به عنوان یک نماد فرهنگی در فرانسه و دیگر نقاط جهان نیز شناخته می‌شود. این نماد در کنار کیفیت و نوآوری‌های فنی پژو، به اعتبار برند در بازارهای جهانی افزوده است.

با توجه به تاریخچه غنی و طراحی نمادین، لوگوی پژو نمایانگر تعهد این برند به کیفیت، نوآوری و طراحی است که همواره در راستای پاسخگویی به نیازهای مشتریان و تطابق با تغییرات بازار عمل کرده است.

ین طراحی به وضوح قدرت و شجاعت را منتقل می‌کند و به نوعی نمادی از استحکام و کیفیت بالای خودروهای پژو محسوب می‌شود. شیر به عنوان نماد ملی فرانسه نیز شناخته می‌شود و این انتخاب به تقویت هویت فرانسوی برند کمک می‌کند.

تاریخ لوگوی پژو به اوایل قرن نوزدهم برمی‌گردد. در ابتدا، لوگو تنها شامل نام "پژو" بود، اما با گذشت زمان، طراحی آن به تدریج به سمت تصویر شیر تغییر یافت. در سال ۱۹۴۸، لوگوی شیر به شکل فعلی خود طراحی شد که در آن شیر در حال حرکت و با جزئیات بیشتری به تصویر کشیده شده است. این تصویر به نوعی نشان‌دهنده نوآوری و پویایی پژو در صنعت خودروسازی است.

طراحی لوگوی پژو نه تنها به زیبایی آن اهمیت می‌دهد، بلکه به معانی عمیقی نیز اشاره دارد. شیر به عنوان نماد قدرت و تسلط، نشان‌دهنده تعهد پژو به تولید خودروهایی با عملکرد بالا و فناوری پیشرفته است. این برند همواره در تلاش است تا با ارائه محصولات باکیفیت و استفاده از فناوری‌های نوین، رضایت مشتریان خود را جلب کند.

در سال‌های اخیر، پژو با به‌روزرسانی لوگوی خود تلاش کرده است تا به تصویر مدرن‌تری دست یابد. این به‌روزرسانی‌ها شامل تغییرات جزئی در طراحی شیر و رنگ‌ها بوده که به لوگو ظاهری شیک و معاصر بخشیده است. با این حال، روح اصلی لوگو که همان نماد قدرت و کیفیت است، حفظ شده است.

در نهایت، لوگوی پژو نه تنها یک نماد تجاری است، بلکه نمایانگر تاریخ، فرهنگ و فلسفه برند است. این لوگو به عنوان نشانه‌ای از تعهد پژو به نوآوری و کیفیت، در ذهن مشتریان و علاقه‌مندان به خودرو جایگاه ویژه‌ای دارد.

I just got this message through linkedin. That's more econ job openings at one place than I've ever seen. From scrolling through, they appear to mostly be with the IRS and based outside of DC. In a normal job market year, there are fewer than 1000 economist job openings in the entire country, IIRC.

Does anyone know what this is?

Trump's complete failure to put a dent in the administrative state led many to conclude that it's a hopeless effort. Even Vivek is being too clever by half with the schemes he's concocting.

The main hurdle in significantly scaling down the Federal Government is that it's very difficult to fire anyone. I think most of the employees are unionized and they have all sorts of protections, regardless.

The easiest path is not to fire people, it's to make them voluntarily quit. A few years ago, Trump relocated the USDA to Kansas City. This was big news amongst economists, because so many work for the USDA. The vast majority of USDA economists quit, rather than move to Kansas City. I imagine that was also the case for other USDA employees. If Trump had been smart, he would have taken the opportunity to cut the USDA personnel budget. That would have stopped them from staffing back up, which I imagine they've done by now.

So, the easy to implement plan for draining the swamp is to just move all of the agencies out of DC and into places where snobby elites don't want to live. Then, after the mass resignations, cap the personnel budgets at much lower levels.

There are added governance benefits like making it more difficult to lobby and reducing costs per worker.

Another option that would likely cause mass resignations would be to make all positions remote and then take away cost of living adjustments. Right now, government employees get paid more for living in expensive places. If they were remote, then there's no rationale for keeping that, since they could live in a less expensive place.

A response to Achim Warner's "Drivechain brings politics to miners" article

I mean this article: https://achimwarner.medium.com/thoughts-on-drivechain-i-miners-can-do-things-about-which-we-will-argue-whether-it-is-actually-a5c3c022dbd2

There are basically two claims here:

1. Some corporate interests might want to secure sidechains for themselves and thus they will bribe miners to have these activated

First, it's hard to imagine why they would want such a thing. Are they going to make a proprietary KYC chain only for their users? They could do that in a corporate way, or with a federation, like Facebook tried to do, and that would provide more value to their users than a cumbersome pseudo-decentralized system in which they don't even have powers to issue currency. Also, if Facebook couldn't get away with their federated shitcoin because the government was mad, what says the government won't be mad with a sidechain? And finally, why would Facebook want to give custody of their proprietary closed-garden Bitcoin-backed ecosystem coins to a random, open and always-changing set of miners?

But even if they do succeed in making their sidechain and it is very popular such that it pays miners fees and people love it. Well, then why not? Let them have it. It's not going to hurt anyone more than a proprietary shitcoin would anyway. If Facebook really wants a closed ecosystem backed by Bitcoin that probably means we are winning big.

2. Miners will be required to vote on the validity of debatable things

He cites the example of a PoS sidechain, an assassination market, a sidechain full of nazists, a sidechain deemed illegal by the US government and so on.

There is a simple solution to all of this: just kill these sidechains. Either miners can take the money from these to themselves, or they can just refuse to engage and freeze the coins there forever, or they can even give the coins to governments, if they want. It is an entirely good thing that evil sidechains or sidechains that use horrible technology that doesn't even let us know who owns each coin get annihilated. And it was the responsibility of people who put money in there to evaluate beforehand and know that PoS is not deterministic, for example.

About government censoring and wanting to steal money, or criminals using sidechains, I think the argument is very weak because these same things can happen today and may even be happening already: i.e., governments ordering mining pools to not mine such and such transactions from such and such people, or forcing them to reorg to steal money from criminals and whatnot. All this is expected to happen in normal Bitcoin. But both in normal Bitcoin and in Drivechain decentralization fixes that problem by making it so governments cannot catch all miners required to control the chain like that -- and in fact fixing that problem is the only reason we need decentralization.

There is a famous saying that goes, "In the land of the blind, the one-eyed man is king."

This saying is related to one of the most famous short stories in English literature, "The Country of the Blind," written by the renowned British author H.G. Wells, who is considered a pioneer of science fiction and gained fame for his works in that genre.

The story narrates the plight of a group of immigrants from Peru who fled Spanish tyranny. At that time, Peru, located in western South America, was under Spanish rule.

The story's author describes a strange disease that spread in a remote village isolated from the world in the Andes mountains of Peru, causing the villagers to become blind. From that moment on, their contact with the outside world was severed, and they never left their village. They adapted to their blindness and bore blind children from generation to generation until all the villagers were blind, with not a single sighted person among them.

One day, while a mountaineer among the immigrants was practicing his hobby, his foot slipped, and he fell from the summit into the village. The man was unharmed as he landed on the snow-covered trees of the village. His first observation was that the houses had no windows, and their walls were painted in bright and chaotic colors. He thought to himself, "The person who built these houses must be blind."

As he ventured further into the village, he began calling out to the people and noticed that they passed by him without noticing. It was then that he realized he was in the "Country of the Blind." He approached a group of people and started introducing himself, explaining who he was and the circumstances that led him to their village, and how people in his land could "see."

As soon as he uttered the word "see," he sensed the danger of the situation, and a barrage of questions followed: What does 'see' mean? How? In what way do people see? The villagers mocked him and began laughing. They even went so far as to accuse him of madness and decided that some should remove his eyes, considering them a source of his delusion and insanity.

The protagonist, Nions, failed to explain the concept of sight and how to convey the idea of vision to those who cannot see. He fled before they could tear out his eyes, questioning how blindness could be deemed normal while sight was considered a disease.

"The Country of the Blind" represents any society dominated by ignorance, chaos, corruption, backwardness, poverty, violence, and intolerance due to unsuitable and prevailing ideas, where any enlightening call is met with rejection, suspicion, and violence.

Existem sistemas integrados de decisões coletivas que chaveiam os destinos de povos, em interno ao sistema há uma vasta rede de discursos e escolhas colaterais que geram variantes sobre os futuros dos indivíduos, que mesmo sobre interindependência ainda estão dentro de uma lógica superior qual rege as sociedades e civilizações humanas. No geral é inevitável que o ser não isolado em sua própria realidade, assim então desperto e não imerso para a optica geral coletiva , em oposição à óptica singular do indivíduo — desperto sobre sua realidade e imerso na Janela de Overton — se vê como parte do processo, porém erroneamente se vê como sujeito da ação que rege as decisões, não como o que de fato é: uma ferramenta dos sujeitos reais da ação. O eleitor é o número, a eleição é o espetáculo, os políticos são os atores e quem o planeja são os "Senhores", dessa forma explicitamos o fim do espetáculo.

Sobretudo, há um padrão na literatura universal: a vilania está sempre em posição de poder, isso pois destaca a ameaça por via da força, e quem a detém é geralmente alguém que possui as ferramentas políticas para tal, sejam elas lícitas ou ilícitas, sejam eles presentes no estamento burocrático ou não, porém há o segundo padrão: a vilania sempre busca a ascenção por via da subversão. É comum que essa subversão passe pela transição do lícito pelo ilícito, motivo pelo qual os ditadores possuem relações com máfias, grupos narcoterroristas, facções terroristas e etc. Por além do segundo padrão, há o terceiro: o poder oculto. Entre esses podemos traçar um paralelo entre o recém "reeleito" Nicolás Maduro e o Deep State americano, e assim podemos explicitar, além do sucesso de um deus, a verdadeira vitória da "democracia".

A priori a representação do arquétipo vilanesco de Anticristo comumente dá sua face por cima de uma escada em obras de ficção, assim ocorre em referência à simbologia esotérica da ascenção espiritual, isso em alto grau de elavação, porém por um poder imanente. No presente momento político dos povos o Anticristo está sobre o topo das escadas tal como nas ficções, lá se apresenta no topo de sua suposta "glória" para expor, de alto e bom tom, quem realmente manda e desmanda na ordem dos eventos, e de onde esse poder emana, no caso, do deus em oculto por de trás da grande cortina violeta, qual vemos como "democracia". Em uma subversão lógica, desconstruindo os valores universais católicos-cristãos quais organizaram o Ocidente, o Anticristo não é um "vilão", mas sim um herói do destino dos povos, trata-se do libertador, do homem que unirá tudo e todos e consolidará o avanço na luta contra Deus, ou então, contra o demiurgo, portanto, esse Anticristo há de herdar as vontades de Azazel e a manifestação do mal sobre a humanidade, qual gerou a nós o anátema. A modernidade nos ensinou a condenar Deus por decorrência do anátema, nos ensina que o pecado é o caminho da liberdade, e assim nos incentiva à negá-lo, primeiro como Deus e segundo como Verdade, assim nos ensina também que Cristo é um problema a ser superado e que todos os elementos que inibem a força revolucionária coletivista na derrubada da autoridade do Deus trinitário cristão-católico devem ser destruidos, em paralelo preza-se pelo levantamento de novos deuses, assim saímos de um período de destruição para adentrarmos o levantamento de novas divindades, essas quais estão presentes nos projetos de Estado.

De forma prática, foi visto ontem, no dia 28 de julho, a vitória da "democracia" na eleição fraudada de Nicolás Maduro, essa comemorada por dois grupos em específico: os socialistas ortodoxos, como a turma do PCO & amigos, e os "socialistas de direita", como os adeptos do dugnismo pró-eurasiano, adeptos esses quais recebem apelidos de "naCHIoNAlistas" e "russófilos", em exemplo o grupo Nova Resistência. O processo eleitoral foi efetuado estrategicamente para 1- mostrar ao povo que a lei não importa mais, o que importa é a ordem, assim para gerar imponência sobre a população e fazê-la entender que ou se é venezuelano e está com Maduro ou está convidado a se retirar do país pois a opinião de massas não destruirá mais o poder instituido pelos bolivarianistas e pelo narcotráfico, e 2- gerar falsas esperanças aos opositores, que sem cautela e em histeria usaram da voz para atacar o soberano da política venezuelana crendo piamente na lisura e chance de vitória, não somente destinado a expor a inescrupulosidade dos liberais antichavistas, como dos simpatizantes internacionais ao fim do regime ditatorial de Nicolás Maduro. O fato é que a Venezuela, a partir dessas eleições, se torna um caso indenfensável para aqueles que buscam conciliar o socialismo com a democracia, pois trata-se de um Estado de exceção qual a lei não possui autoridade frente aos planos e projetos políticos, que preponderam em avanço sem freios, a defesa do regime de Maduro está nas mãos dos dois grupos anteriormente citados, compostos por uma nata bastante duvidável das bolhas dentro das guerrilhas informacionais no universo das propagandas políticas massivas, e que é tão inescrupulosa como a porção caricata da suposta "direita latino-americana", essa ecumênica, laical, maçônica e liberal.

Ocorre que esses citados já não buscam o mantra da democracia para proteger seus ideais, o oposto, partindo deles há a defesa do fim do modelo democrático, o que por vez não é errado, desde que tal bandeira não seja usada para defesa de tiranos e de tiranias, o que é o caso presente. Dos caminhos presentes para a permanência da posição de defesa do regime de Maduro há mais um, além da defesa do fim das democracias, e é a defesa da democracia "herdada", que na prática é o uso da mentira para induzir as massas a crerem que o desejo do povo se faz por uma consquência progressiva e histórica da manifestação dos anseios populares, independentemente da resposta popular nas urnas, que o desejo das gerações passadas era por uma Venezuela socialista, esses desejos foram transmitidos ao regime legal e democrático de Chavez, que foi procedido por seu herdeiro, Maduro, e que a partir disso é legítimo a perpetuação do poder político de Maduro independente dos desejos populares presentes das "massas alienadas". O problema dessa posição é a crença de que as posições de aceitação e rejeição são imutáveis e que os desejos são eternos, que os povos não se tranformam racionalmente e que a estrutura política é uma força regente dos povos de forma ampla, como se da política viessem os avanços técnicos, tecnológicos, de pensamento, de conhecimento, de saberes, moral, ético, cultural e etc., ou que inexistem as decadências civilizacionais e culturais, e claro, se houver legitimidade na democracia herdada então haveria legitimidade na consolidação dos chauvinismos do século XX em retorno ao século XXI, amplamente rejeitados hoje pela sociedade civil, anacronicamente, trata-se então de um apelo desesperador por parte de uns, algo insustentável, logo àquele que se por em defesa da democracia "herdada" se colocará, mais cedo ou mais tarde, em defesa do fim das democracias.

Assim, em paralelo, outro anticristo se mostra presente no topo das escadas, esse menos personalista, trata-se do poder oculto norte-americano, que está em via de 1- permitir a vitória de Donald Trump e ver suas partes serem perseguidas, presas, ou banidas do país, e 2- manipular os resultados para vencer na marra, algo possível. Se ocorrida a primeira possibilidade de evento o deep state americano terá uma luta mais árdua contra seu presente inimigo, os esforços serão maiores para manter a estabilidade política frente a decadência dos Estados Unidos na nova configuração global das esferas de poder e influência no mundo, a estabilidade deverá se tornar instabilidade para que haja chances de sobrevivência do deep state e uma possível destruição completa da direita, assim consolidando o poder que guiará a construção de uma nova civilização sobre a findada "cultura americana", será o fim do processo dialético que move a política repúblicana nas "democracias", issso em território americano, pois do oposto o processo dialético então referido se delonga. Na segunda possibilidade os EUA decreta seu fim em benefício do avanço exponencial do poder das elites financistas, o povo americano será o povo sacrificado para a consolidação de um novo futuro para os povos do mundo, pois esses serão responsáveis infelizes pelo financiamento de conflitos mundo a fora de forma mais vil e truculenta, visando manter ainda forte o poder do deep state por via da corrupção, assim a guerra ao dinheiro será mantida, sem retorno.

Quando o anticristo descer as escadas estaremos em outro cenário, então entenderemos o que é um "plano" muito bem arquitetado, e então perceberemos que a democracia não é um deus falho, pelo contrário, a democracia liberal é um deus que obteve sucesso em seu dever de consolidar a tirania sofisticada e oculta por via da grande mentira democrática. O poder nunca se tratou de capacidade de mover as massas, mas sim do domínio sobre a subversão da realidade, para que então esteja dentro da guerra pela destruição da criatura e tenha seu espaço concedido numa elite burocrática ou financeira, isso é possível se o soberano detém a imprensa e o poder monetário (sobre a moeda nacional) nas mãos.

A movimentação processual desses sistemas integrados de decisões sobre os rumos dos povos tenderão a levar a humanidade para uma autodestruição, as civilizações serão atacadas para o avanço de um mundo primeiro multipolar para que depois opere conforme os sonhos da "República Universal", no momento aqueles que acreditam na lisura, nas leis e na suposta benevolência dos Estados nacionais para guiar os povos à liberdade são partes do problema, são financiadores contumazes da destruição e da luta contra Deus, uma vez que abraçam as mentiras para defender o poder estatal de forma análoga ao poder divino. Para esses, defender um projeto, um plano, um futuro, é mais importante do que aceitar a Verdade revelada, é claro, esses quais me refiro estão sobre o lado das massas, pois a violência contra Deus passa a preponderar no lado daqueles que estão dentre as forças regentes, nesse caso sem cogitar em pedir perdão à Deus pelas ofensas e pelas blasfêmias.

For those unfamiliar with my nostrminusnostr project, it filters out notes about bitcoin and nostr on the nostr protocol. The goal is to create a place where people can actual use nostr to discuss something other than nostr. Today I'd like to unveil the kittens tab.

https://nostrminusnostr.vercel.app/kittens

This isn't a filter to kittens and puppies in the same way that the sports tab filters in only sports content. Instead, I've replaced every reference to nostr or bitcoin with a reference to puppies and kittens. Also, people that didn't write a bio each get to share a fun doggy fact and all pictures are of cats and dogs. Some of the results are quite funny if I do say so myself.

The goal: you can still get your bitcoin and nostr news on nostr without actually reading those words over and over and over and over and over again. I hope this helps.

Sadly, they do not. He should, of course, cut them some slack since...you know...they're dogs.

a FEAST for the eyes

Not really. It's just a dog.

Anywho, enjoy.

Using Spacechains and Fedimint to solve scaling

What if instead of trying to create complicated "layer 2" setups involving noveau cryptographic techniques we just did the following:

• we take that Fedimint source code and remove the "mint" stuff, and just use their federation stuff secure coins with multisig;
• then we make a spacechain;
• and we make the federations issue multisig-btc tokens on it;
• and then we put some uniswap-like thing in there to allow these tokens to be exchanged freely.

Why?

The recent spike in fees caused by Ordinals and BRC-20 shitcoinery has shown that Lightning isn't a silver bullet. Channels are too fragile, it costs a lot to open a channel under a high fee environment, to run a routing node and so on.

People who want to keep using Lightning are instead flocking to the big Lightning custodial providers: WalletofSatoshi, ZEBEDEE, OpenNode and so on. We could leverage that trust people have in these companies (and individuals) operating shadow Lightning providers and turn each of these into a btc-token issuer. Each issue their own token, transactions flow freely. Each person can hold only assets from the issuers they trust more.

Just malinvestiment

Traditionally the Austrian Theory of Business Cycles has been explained and reworked in many ways, but the most widely accepted version (or the closest to the Mises or Hayek views) view is that banks (or the central bank) cause the general interest rate to decline by creation of new money and that prompts entrepreneurs to invest in projects of longer duration. This can be confusing because sometimes entrepreneurs embark in very short-time projects during one of these bubbles and still contribute to the overall cycle.

The solution is to think about the "longer term" problem is to think of the entire economy going long-term, not individual entrepreneurs. So if one entrepreneur makes an investiment in a thing that looks simple he may actually, knowingly or not, be inserting himself in a bigger machine that is actually involved in producing longer-term things. Incidentally this thinking also solves the biggest criticism of the Austrian Business Cycle Theory: that of the rational expectations people who say: "oh but can't the entrepreneurs know that the interest rate is artificially low and decide to not make long-term investiments?" ("and if they don't know they should lose money and be replaced like in a normal economy flow blablabla?"). Well, the answer is that they are not really relying on the interest rate, they are only looking for profit opportunities, and this is the key to another confusion that has always followed my thinkings about this topic.

If a guy opens a bar in an area of a town where many new buildings are being built during a "housing bubble" he may not know, but he is inserting himself right into the eye of that business cycle. He expects all these building projects to continue, and all the people involved in that to be getting paid more and be able to spend more at his bar and so on. That is a bet that may or may not end up paying.

Now what does that bar investiment has to do with the interest rate? Nothing. It is just a guy who saw a business opportunity in a place where hungry people with money had no bar to buy things in, so he opened a bar. Additionally the guy has made some calculations about all the ending, starting and future building projects in the area, and then the people that would live or work in that area afterwards (after all the buildings were being built with the expectation of being used) and so on, there is no interest rate calculations involved. And yet that may be a malinvestiment because some building projects will end up being canceled and the expected usage of the finished ones will turn out to be smaller than predicted.

This bubble may have been caused by a decline in interest rates that prompted some people to start buying houses that they wouldn't otherwise, but this is just a small detail. The bubble can only be kept going by a constant influx of new money into the economy, but the focus on the interest rate is wrong. If new money is printed and used by the government to buy ships then there will be a boom and a bubble in the ship market, and that involves all the parts of production process of ships and also bars that will be opened near areas of the town where ships are built and new people are being hired with higher salaries to do things that will eventually contribute to the production of ships that will then be sold to the government.

It's not interest rates or the length of the production process that matters, it's just printed money and malinvestiment.

This is a question I mull over occasionally. We hear about "toxic masculinity" all the time and I think it's a perfectly easy concept to grasp. That implies there's a healthy masculinity, but we don't hear about that nearly as often.

This topic popped into my head while watching the Trump assassination attempt video. My eyes were drawn to the men in the background who dove to cover their loved ones. In particular, I noticed one man who was apparently there with his kid and I could feel his terror as he covered his kid with his body until well after the shots stopped. It's hard to convey to those without kids how resonant that imagery is. Then we find out that the man who died, Corey Comperatore, was shielding his family with his body. In my book, that's as masculine as it gets and that man is as big of a hero as anyone can be.

I was listening to Part of the Problem earlier today and they were talking about masculinity. Dave was making fun of the lame superficial internet version that's embodied by Andrew Tate. His take was that masculinity boils down to "protection and provision". They also discussed the importance of being "peaceful, but not harmless" and how being harmless is essentially the least masculine trait.

At the heart of this, there's a recognition that ultimately we are more expendable than our loved ones and we need to be able to act on that.

What do you all think? I'm eager to hear your thoughts.

hledger-web

A Haskell app that uses Miso and hledger's Haskell libraries plus ghcjs to be compiled to a web page, and then adds optional remoteStorage so you can store your ledger data somewhere else.

This was my introduction to Haskell and also built at a time I thought remoteStorage was a good idea that solved many problems, and that it could use some help in the form of just yet another somewhat-useless-but-cool project using it that could be added to their wiki.

Moshi, Tanzania

Ah, the sweet escape of a charming café. As I sit here, sipping on a cappuccino, the gentle hum of my laptop provides a comforting backdrop to the bustling afternoon. For the past few days, I’ve been immersed in the digital world, meticulously sorting through years of photos. With a decent internet connection at my hostel, I finally managed to download my Google Photos archive and embark on this daunting task.

Progress is slow but steady. I’ve managed to categorize all my photos up until the end of 2023 into daily folders. Now comes the more challenging part: tackling 2024 and organizing all of them by location. It's a labor of love, but one that will undoubtedly pay off in the long run.

Today, Moshi decided to throw a curveball. A widespread power outage forced me to seek refuge in a café with reliable electricity. Luckily, I stumbled upon the delightful Union Café, a haven of calm amidst the chaos. While it lacked internet, at least I could charge my depleted devices.

My brief escape from the hostel also provided an opportunity to capture some street scenes. Unfortunately, the joy of photography was quickly overshadowed by the relentless pursuit of eager salesmen. It seems as though every white person is a walking ATM in this part of the world. The situation has worsened compared to my previous visits, and it's disheartening to see Tanzania following Kenya's footsteps in this regard.

On a personal note, my neck is aching, and a massage sounds like pure bliss. However, the fear of being scammed is holding me back. For now, it's time to pay the 5,000 TZS cappuccino bill and head back to the hostel.

I've decided to give Digikam another shot for photo management. Despite some initial hiccups with importing from Google Photos, I'm hopeful that it will be the right tool for the job. I'll experiment with other features over the next few days.

As the day winds down, I'm eager to share more about my Moshi adventures, including photos from my stroll. But for now, it's time to relax and recharge. Stay tuned for more updates!
