2025-04-28 01:58:55This is a long form test note from Untype.app
Seems like this could work well.
Here is a photograph of the infamous red firebird that has been in the same spot for over 10 years.
There is a header image up top as well. Will that be seen? Maybe?
Clean interface and you're able to type and see a preview window of what your post would like. Cool!
Text before the image prompt makes this lettering large and bold.
Here is a line break
Let me know if you can see this text that is now under the image.

2025-04-28 01:40:46ในวันที่ "วีแกนแบบ non natural" กลายเป็นเทรนด์ระดับโลก แต่การขาดวิตามิน B12 ยังคงเป็นจุดอ่อนที่ทำให้ชาวพืชล้วนหลายคนต้องหาวิธีเสริม เพื่อไม่ให้เสียหน้า Sebastian Joy ก็ได้ฤกษ์เปิดตัว "ยาสีฟันเสริมวิตามิน B12" ชิ้นแรกของโลก พร้อมงานวิจัยรองรับจาก IFANE (Institute for Alternative and Sustainable Nutrition) ว่ามันเวิร์กจริง…อย่างน้อยในห้องทดลอง
แล้วมันคืออะไร? แหล่งที่มาของวิตามิน B12 ในนั้นมาจากไหน? วิตามิน B12 ที่ใช้ในยาสีฟันนี้ เป็นสิ่งที่เรียกว่า "ไซยาโนโคบาลามิน" (Cyanocobalamin) ซึ่งเป็นรูปแบบสังเคราะห์ที่ราคาถูก ผลิตจากแบคทีเรียในห้องแล็บ ไม่ใช่ B12 ที่ได้จากอาหารธรรมชาติ เช่น ตับวัว หรือไข่ไก่แบบที่ร่างกายวิวัฒนาการมาใช้หลายแสนปี
พูดง่าย ๆ คือ มันคือ "วิตามินโรงงาน" ไม่ใช่วิตามินที่มาพร้อมสารอาหารซับซ้อนอื่น ๆ ที่ธรรมชาติใส่มาให้ (เช่น โคแฟกเตอร์ต่าง ๆ ที่ช่วยให้ดูดซึมได้ดีขึ้น) ซึ่งการใช้วิตามินสังเคราะห์ต่อเนื่องนาน ๆ มีรายงานบางชิ้นที่แอบกระซิบว่า อาจไปก่อให้เกิดอนุมูลอิสระหรือความเครียดออกซิเดชันในร่างกายได้
โดสต่อครั้งเท่าไร? ใช้แค่แปรงฟันพอจริงหรือ? ข้อมูลที่มีอยู่บอกว่า ยาสีฟันของ Sebastian ใส่วิตามิน B12 ประมาณ 100 ไมโครกรัม ต่อการแปรงฟันหนึ่งครั้ง ซึ่งหากแปรงวันละสองครั้ง ก็จะได้ราว 200 ไมโครกรัมต่อวัน ถือว่าเกินค่า RDA (ปริมาณที่แนะนำ) ที่อยู่แค่ประมาณ 2.4 ไมโครกรัม ต่อวันสำหรับผู้ใหญ่ธรรมดาไปหลายสิบเท่า! แต่…เขาก็อ้างว่าวิตามินที่แปรงลงไป มีสัดส่วนการดูดซึมจริงๆ "แค่บางส่วน" เพราะฉะนั้นการให้โดสสูงมาก จึงถือว่า "ปลอดภัย" ในมุมมองของพวกเขา
ถ้าได้รับมากเกินไป จะเกิดอะไรขึ้น? ในระยะสั้น วิตามิน B12 เป็นวิตามินละลายน้ำ ถ้าเกินความต้องการร่างกายจะขับออกทางปัสสาวะเป็นหลัก แต่ในระยะยาว งานวิจัยบางชิ้นพบความสัมพันธ์ระหว่างระดับ B12 ที่สูงผิดปกติในเลือด กับการก่อภาวะ oxidative stress ที่ทำให้เซลล์ถูกทำลายเร็วขึ้นและอย่าตัว ไซยาโนโคบาลามิน เมื่อร่างกายเอาไปแปลงเป็นแบบ active (Methylcobalamin หรือ Adenosylcobalamin) จะปล่อย "ไซยาไนด์" จิ๋วๆออกมานิดหน่อยด้วยนะ ถึงจะน้อยมากจนไม่ก่อพิษทันที แต่ถ้าเป็นคนที่มีกำจัดไซยาไนด์ได้ไม่ดี เช่น คนที่มีปัญหาเมตาบอลิซึมผิดปกติ ก็มีความเสี่ยงสะสมได้เช่นกัน
ต่างกับ B12 ที่อยู่ในเนื้อสัตว์ตามธรรมชาติ (เช่น ตับ ไข่แดง ปลาซาร์ดีน เนื้อวัว) ส่วนใหญ่เป็นในรูปแบบ Methylcobalamin และ Adenosylcobalamin อยู่แล้ว คือมาแบบ Active form พร้อมใช้ ไม่ต้องเปลี่ยนสภาพอะไรเพิ่มเติมในร่างกาย ไม่มีการปล่อย "ไซยาไนด์" เพราะไม่ต้องแปลงจากไซยาโนโคบาลามินเหมือนวิตามินสังเคราะห์ที่เอาไปใส่ในยาสีฟันหรืออาหารเสริม แต่อย่างไรก็ตาม มันก็ไม่ได้น่ากลัวอะไรขนาดนั้นครับ ไม่ใช่ประเด็นอะไรมากมาย ข้ามไปได้ถ้าไม่กังวลเพราะแค่นี้หลายคนก็จี๊ดใจหูหักกันไปเยอะแล้ว โอเคข้าม point ยิบย่อยไปครับ
ที่นำมาคุยกันก็แค่เหตุผลที่ว่า "ยาสีฟันตัวนี้ เป็นสินค้านำร่อง" ที่ผลักดันชื่อของ Sebastian Joy เป็นจุดเริ่มต้นของอะไรหลายๆอย่าง ที่จะเล่าให้ในตอนต่อไปครับ
อ่อแล้วยาสีฟันนี้มีแผนบังคับใช้ในอนาคตมีไหม? ตัวยาสีฟันเองน่าจะเป็นการพูดถึงในกลุ่มวีแกนได้ดี นอกจากนี้ให้สังเกตว่า ProVeg และเครือข่ายของเขา ผลักดันแนวคิด keyword ที่ว่า "ถ้าคุณกินพืช คุณต้องเสริม B12" อย่างหนักมากและมีการเสนอว่าการผลิตอาหารจากพืชเชิงอุตสาหกรรมควร "fortify" หรือ "เสริมวิตามิน" เป็นมาตรฐาน เพื่อหลีกเลี่ยงข้อครหาว่า "อาหารพืชทำให้ขาดสารอาหาร" ตรงนี้คือจุดน่าสนใจ ในแผนระยะยาว ถ้าสังคมยอมรับแนวคิดนี้ได้ การที่สินค้าจากพืชเสริมวิตามินแบบ "บังคับ" อาจกลายเป็นเรื่องปกติ ซึ่งจะยิ่งเพิ่มอำนาจให้กลุ่มบริษัทผลิตวิตามินสังเคราะห์รายใหญ่ที่ใช้การเพาะเชื้อแบคทีเรียจำเพาะ อยู่เบื้องหลัง เป็นเศรษฐกิจแบบ "สารอาหารที่มนุษย์สร้างขึ้น" ที่เราอาจต้องออกมานั่งน้ำตาคลอริมทุ่งอีกหลายรอบ จำได้ไหมครับกระบวนการใช้การเพาะเชื้อแบคทีเรียจำเพาะ จุดต่างๆที่ผมไล่เขียนไว้ก่อนหน้านี้ เริ่มนำมาขีดเส้นเข้าหากันได้บ้างแล้ว (ใครที่งง ผมคงต้องบอกว่า งานนี้ยาวครับ ผมโพสทุก 8.00 มาร่วมเดือนแล้ว ต้องขยันย้อนแล้วหละครับ)
เพราะโลกแห่งความเป็นจริง จะ animal หรือ plant ก็ตามขอให้เป็นของธรรมชาติ และได้รับการ "เลือก" โดยผู้คนว่าจะกินอะไร ไม่ใช่การเดินสู่ช่อง "สิ้นสุดทางเลือก"
เลิกเถียงเรื่องการใช้ไดเอท แล้วมาร่วมกันมองข้างหน้าว่า คุณจะยังมีสิทธิ์เลือกอะไรได้อีกไหม ก่อนวันนั้นจะมาถึงครับ
ปล. เสริมเรื่องนี้ให้เผื่อใครจะสนใจไปค้นต่อนะครับ Cyanocobalamin เป็น B12 รูปแบบที่เสถียรที่สุดและราคาถูกที่สุดในการผลิตเชิงอุตสาหกรรม เพราะมันไม่สลายง่ายเมื่อเจอแสงหรือออกซิเจน การผลิตจะใช้การเพาะเชื้อแบคทีเรียจำเพาะ (เช่น Propionibacterium freudenreichii หรือ Pseudomonas denitrificans) ที่ผ่านการดัดแปลงพันธุกรรม หรือควบคุมสภาพการผลิตในไบโอรีแอคเตอร์ขนาดใหญ่
Cyanocobalamin จะปล่อยไซยาไนด์ประมาณ 1 โมเลกุลต่อ 1 โมเลกุล B12 ที่ถูกแปลง ซึ่งโดยปกติร่างกายดีท็อกซ์ได้ถ้าได้รับปริมาณน้อย แต่สำหรับคนที่มีภาวะการดีท็อกซ์บกพร่อง เช่น คนที่มีปัญหา MTHFR mutation หรือโรคไตเรื้อรัง อาจเป็นเรื่องที่ต้องระวัง
วิตามิน B12 จากตับวัว, ไข่, หรือปลา เช่น แซลมอน จะมาในฟอร์ม active อยู่แล้ว เช่น Methylcobalamin หรือ Adenosylcobalamin ไม่ต้องเสียพลังงานหรือเสี่ยงปล่อยไซยาไนด์ #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

2025-04-28 01:05:49Eu reconheço que Deus, e somente Deus, é o soberano legítimo sobre todas as coisas. Nenhum homem, nenhuma instituição, nenhum parlamento tem autoridade para usurpar aquilo que pertence ao Rei dos reis. O Estado moderno, com sua pretensão totalizante, é uma farsa blasfema diante do trono de Cristo. Não aceito outro senhor.
A Lei que me guia não é a ditada por burocratas, mas a gravada por Deus na própria natureza humana. A razão, quando iluminada pela fé, é suficiente para discernir o que é justo. Rejeito as leis arbitrárias que pretendem legitimar o roubo, o assassinato ou a escravidão em nome da ordem. A justiça não nasce do decreto, mas da verdade.
Acredito firmemente na propriedade privada como extensão da própria pessoa. Aquilo que é fruto do meu trabalho, da minha criatividade, da minha dedicação, dos dons a mim concedidos por Deus, pertence a mim por direito natural. Ninguém pode legitimamente tomar o que é meu sem meu consentimento. Todo imposto é uma agressão; toda expropriação, um roubo. Defendo a liberdade econômica não por idolatria ao mercado, mas porque a liberdade é condição necessária para a virtude.
Assumo o Princípio da Não Agressão como o mínimo ético que devo respeitar. Não iniciarei o uso da força contra ninguém, nem contra sua propriedade. Exijo o mesmo de todos. Mas sei que isso não basta. O PNA delimita o que não devo fazer — ele não me ensina o que devo ser. A liberdade exterior só é boa se houver liberdade interior. O mercado pode ser livre, mas se a alma estiver escravizada pelo vício, o colapso será inevitável.
Por isso, não me basta a ética negativa. Creio que uma sociedade justa precisa de valores positivos: honra, responsabilidade, compaixão, respeito, fidelidade à verdade. Sem isso, mesmo uma sociedade que respeite formalmente os direitos individuais apodrecerá por dentro. Um povo que ama o lucro, mas despreza a verdade, que celebra a liberdade mas esquece a justiça, está se preparando para ser dominado. Trocará um déspota visível por mil tiranias invisíveis — o hedonismo, o consumismo, a mentira, o medo.
Não aceito a falsa caridade feita com o dinheiro tomado à força. A verdadeira generosidade nasce do coração livre, não da coerção institucional. Obrigar alguém a ajudar o próximo destrói tanto a liberdade quanto a virtude. Só há mérito onde há escolha. A caridade que nasce do amor é redentora; a que nasce do fisco é propaganda.
O Estado moderno é um ídolo. Ele promete segurança, mas entrega servidão. Promete justiça, mas entrega privilégios. Disfarça a opressão com linguagem técnica, legal e democrática. Mas por trás de suas máscaras, vejo apenas a velha serpente. Um parasita que se alimenta do trabalho alheio e manipula consciências para se perpetuar.
Resistir não é apenas um direito, é um dever. Obedecer a Deus antes que aos homens — essa é a minha regra. O poder se volta contra a verdade, mas minha lealdade pertence a quem criou o céu e a terra. A tirania não se combate com outro tirano, mas com a desobediência firme e pacífica dos que amam a justiça.
Não acredito em utopias. Desejo uma ordem natural, orgânica, enraizada no voluntarismo. Uma sociedade que se construa de baixo para cima: a partir da família, da comunidade local, da tradição e da fé. Não quero uma máquina que planeje a vida alheia, mas um tecido de relações voluntárias onde a liberdade floresça à sombra da cruz.
Desejo, sim, o reinado social de Cristo. Não por imposição, mas por convicção. Que Ele reine nos corações, nas famílias, nas ruas e nos contratos. Que a fé guie a razão e a razão ilumine a vida. Que a liberdade seja meio para a santidade — não um fim em si. E que, livres do jugo do Leviatã, sejamos servos apenas do Senhor.

2025-04-28 01:05:08Primeiramente, o que é mempool?
Abreviação de memory pool (ou "pool de memória") a mempool é uma espécie de fila onde as transações de Bitcoin ficam temporariamente armazenadas antes de serem confirmadas e incluídas em um bloco na blockchain. Quando você realiza uma transação em uma rede blockchain, essa transação precisa ser validada e confirmada pelos mineradores (ou validadores). Porém, ela não é processada instantaneamente. Primeiro, ela vai para a mempool, onde aguarda até que um minerador a selecione para incluir no próximo bloco.
É assim: * Você envia uma transação, ela é transmitida para a rede e vai parar na mempool de vários nós (computadores) que suportam a rede blockchain. * As transações na mempool são organizadas pela taxa de transação que foi anexada. Quanto maior a taxa, mais rápido os mineradores tendem a escolher essa transação para incluí-la em um bloco, pois isso aumenta os ganhos deles. * Os mineradores pegam as transações da mempool, criam um bloco com elas e, ao minerar (confirmar) esse bloco, as transações saem da mempool e entram na blockchain.
Aqui irei usar o site mempool.emzy.de como referência, mas é importante entender que sites de mempool são representações visuais da mempool de um nó específico e não a mempool do Bitcoin em si. Ela não é centralizada, cada nó da rede mantém a sua própria versão da mempool. Assim, ela pode variar de um nó para outro. Esses sites ajudam a visualizar dados sobre transações e taxas.
É uma boa prática usar VPN ou Tor ao acessar tais sites se você estiver verificando uma transação específica sua, pois sua privacidade pode ficar comprometida se o site registrar esses dados. Se você estiver repetidamente acessando-o para monitorar a confirmação de uma transação, alguém pode conseguir correlacionar o endereço IP com essa atividade e revelar uma conexão indireta com o endereço da transação.
Dito isso...
Como interpretar a mempool?
Vamos dividir isso em partes para fins didáticos.
Faixa de taxas
Cada bloco verde representa uma faixa de taxa medida em satoshis por vByte (sats/vB).
Essa unidade de medida representa o valor pago por byte ocupado pela transação.
Quanto maior a taxa paga por uma transação, mais rápido ela tende a ser confirmada.
Quanto maior a transação em bytes, mais você precisa pagar para que ela seja confirmada.
Cada transação Bitcoin consiste em entradas e saídas (inputs e outputs): * Entradas são referências a transações anteriores que estão sendo gastas, e cada entrada inclui informações como o endereço de origem, a assinatura (que valida a transação e pode variar de tamanho dependendo da complexidade da chave e do método de assinatura utilizado (como SegWit, que é mais eficiente). Quanto mais complexa a assinatura, maior será o tamanho em bytes) e outros dados. Quanto mais entradas uma transação tiver, maior será seu tamanho. * Saídas representam o destino do Bitcoin, e quanto mais saídas, maior será o tamanho da transação. Embora as saídas ocupem menos espaço em bytes do que as entradas.Ex.: * ~4 sat/vB: Indica uma taxa média. Significa que, em média, as transações estão sendo processadas a 4 satoshis por vByte; * 3-5 sat/vB: Isso significa que as transações estão sendo processadas com uma taxa entre 3 e 5 satoshis por vByte.
MB
Simplesmente o tamanho do bloco medido em megabytes :)
Número de transações
Essa seção informa quantas transações estão aguardando confirmação para cada faixa de taxa (bloco). Quanto maior o número de transações, maior a demanda pela faixa de taxa especificada.
Tempo estimado para confirmação
Aqui é mostrado o tempo médio de espera para transações que pagam taxas dentro da faixa especificada. Se você pagar uma taxa maior, a transação será confirmada mais rapidamente; uma taxa menor significa que a transação pode levar mais tempo para ser confirmada, especialmente se a rede estiver congestionada.
Esta seção mostra sugestões de taxa em diferentes níveis de prioridade para os usuários:
Sem Prioridade
Exibe a taxa mínima necessária para transações que não precisam de confirmação rápida.
Prioridade Baixa
Sugestão de taxa para transações que podem esperar um tempo moderado, com expectativa de confirmação em um ou dois blocos.
Prioridade Média e Alta
São as faixas de taxa recomendadas para quem precisa que a transação seja confirmada rapidamente. "Prioridade Alta" paga uma taxa maior, garantindo que a transação seja incluída no próximo bloco.
Cada bloco roxo representa um bloco recém-minerado. As informações mostradas incluem:
Taxa média paga
Refere-se à taxa média em satoshis/vB paga por todas as transações incluídas em um bloco recém-minerado. Isso reflete o valor médio que os usuários estão dispostos a pagar para que suas transações sejam confirmadas rapidamente.
Número de transações
Este número indica quantas transações foram processadas no bloco minerado. O tamanho do bloco é limitado, então, quanto maior o número de transações, menor será o espaço disponível para novas transações, o que pode influenciar as taxas de transação.
Tempo desde a mineração
Esta métrica informa quanto tempo se passou desde que o bloco foi minerado e adicionado à blockchain.
Pool de mineração
Exibe o nome do pool de mineração que minerou o bloco, como AntPool. Grandes pools de mineração têm mais chances de minerar blocos regularmente devido ao alto hashrate (medida da capacidade computacional utilizada pelos mineradores) que possuem.
Essa seção mostra informações sobre o ajuste de dificuldade, que ocorre aproximadamente a cada duas semanas.
Tempo médio dos blocos (~9,9 minutos):
Este é o tempo médio atual para minerar um bloco na rede. A meta da rede é manter o tempo de bloco em cerca de 10 minutos; um tempo menor indica um aumento na taxa de hash, ou seja, que mais poder computacional foi adicionado à rede.
Mudança de dificuldade (+1,46%):
A dificuldade ajusta-se a cada 2016 blocos para manter o tempo médio de bloco próximo de 10 minutos. Um aumento na dificuldade, como +1,46%, indica que a mineração ficou mais difícil devido ao aumento do hashrate, enquanto uma redução na dificuldade indica que o hashrate diminuiu.
Tempo até o próximo ajuste:
É o tempo previsto até o próximo ajuste de dificuldade (7 dias, nesse caso), o que é crucial para manter a rede estável e garantir a segurança e a regularidade do processo de mineração.
Quanto tempo demora até o próximo halving, um evento no Bitcoin que ocorre aproximadamente a cada 210.000 blocos minerados, ou cerca de quatro anos. Durante o halving, a recompensa que os mineradores recebem por adicionar um novo bloco à blockchain é reduzida pela metade.
Um diagrama visual da mempool que mostra o estado das transações pendentes na rede.
Tamanhos de blocos
O tamanho de cada quadrado representa o tamanho da transação em bytes.
Filtros (Consolidação, Coinjoin, Dados): Permite visualizar categorias específicas de transações: * Consolidação: Transações de consolidação agrupam pequenos UTXOs em um único UTXO maior para simplificar e baratear futuras transações. (UTXOs merecem um artigo dedicado) * Coinjoin: Transações CoinJoin são usadas para melhorar a privacidade, misturando transações de vários usuários em uma única transação. * Dados: Mostra transações que contêm dados adicionais, que podem incluir informações não financeiras, como mensagens.
Este gráfico exibe o número de transações recebidas ao longo do tempo.
Taxa mínima (1 sat/vB):
Indica a taxa mínima atualmente aceita pela mempool. Se a mempool estiver cheia, transações que paguem menos do que a taxa mínima podem ser excluídas para dar lugar a transações de maior prioridade.
Uso de memória (259 MB / 300 MB):
A mempool tem um limite de memória. Quando está cheia, transações de taxa mais baixa podem ser descartadas para abrir espaço para aquelas com taxas mais altas, priorizando-as para inclusão em blocos.
Transações não confirmadas (59.361):
Indica o número total de transações pendentes que aguardam confirmação. Quanto maior o número de transações na mempool, maior a probabilidade de que as taxas aumentem para garantir uma confirmação mais rápida.
Essa seção mostra transações que foram substituídas utilizando o mecanismo RBF (Replace-By-Fee), que permite substituir uma transação com uma taxa mais alta para acelerar sua confirmação.
TXID
Este é o identificador da transação (Transaction ID), exibido parcialmente para abreviar o espaço. Cada transação tem um identificador único na blockchain.
Previous fee
Exibe a taxa de transação original paga na primeira tentativa, medida em satoshis por vByte (sat/vB). Esta taxa inicial provavelmente era baixa demais, resultando em uma demora na confirmação.
New fee
Mostra a nova taxa de transação, também em satoshis por vByte, definida para substituir a taxa anterior. Uma taxa maior aumenta as chances de inclusão rápida em um bloco.
Status (RBF)
RBF indica que a transação foi substituída utilizando o recurso "Replace-By-Fee". Isso significa que a nova transação cancelou e substituiu a original, e o minerador escolherá a transação com a taxa mais alta para incluir no próximo bloco.
Esta seção lista transações recentes que entraram na mempool e aguardam confirmação.
TXID
Similar ao "Recent Replacements", este é o identificador único da transação.
Amount
Exibe a quantidade de Bitcoin transferida nessa transação, geralmente em frações de BTC (como 0.0001 BTC). Esta é a quantia enviada pelo remetente ao destinatário.
USD
Mostra o valor da transação em dólares americanos (USD), calculado com base na taxa de câmbio atual. Serve para dar uma ideia de quanto a transação representa em moeda fiduciária.
Fee
Exibe a taxa de transação paga, em satoshis por vByte (sat/vB). Uma taxa mais alta em relação à média aumenta a probabilidade de confirmação mais rápida, pois as transações com taxas mais elevadas são priorizadas pelos mineradores.
E acabou. Espero que isso tenha sido útil para você e tenha agregado mais entendimento sobre esse complexo e maravilhoso mundo do Bitcoin. Se foi, considere compartilhar com alguém que precise. E se tem sugestões de melhoria, por favor, não deixe de comentar, o conhecimento está dispero na sociedade.
Por fim, stay humble and stack sats! -
@ 52b4a076:e7fad8bd
2025-04-28 00:48:57I have been recently building NFDB, a new relay DB. This post is meant as a short overview.
Regular relays have challenges
Current relay software have significant challenges, which I have experienced when hosting Nostr.land: - Scalability is only supported by adding full replicas, which does not scale to large relays. - Most relays use slow databases and are not optimized for large scale usage. - Search is near-impossible to implement on standard relays. - Privacy features such as NIP-42 are lacking. - Regular DB maintenance tasks on normal relays require extended downtime. - Fault-tolerance is implemented, if any, using a load balancer, which is limited. - Personalization and advanced filtering is not possible. - Local caching is not supported.
NFDB: A scalable database for large relays
NFDB is a new database meant for medium-large scale relays, built on FoundationDB that provides: - Near-unlimited scalability - Extended fault tolerance - Instant loading - Better search - Better personalization - and more.
Search
NFDB has extended search capabilities including: - Semantic search: Search for meaning, not words. - Interest-based search: Highlight content you care about. - Multi-faceted queries: Easily filter by topic, author group, keywords, and more at the same time. - Wide support for event kinds, including users, articles, etc.
Personalization
NFDB allows significant personalization: - Customized algorithms: Be your own algorithm. - Spam filtering: Filter content to your WoT, and use advanced spam filters. - Topic mutes: Mute topics, not keywords. - Media filtering: With Nostr.build, you will be able to filter NSFW and other content - Low data mode: Block notes that use high amounts of cellular data. - and more
Other
NFDB has support for many other features such as: - NIP-42: Protect your privacy with private drafts and DMs - Microrelays: Easily deploy your own personal microrelay - Containers: Dedicated, fast storage for discoverability events such as relay lists
Calcite: A local microrelay database
Calcite is a lightweight, local version of NFDB that is meant for microrelays and caching, meant for thousands of personal microrelays.
Calcite HA is an additional layer that allows live migration and relay failover in under 30 seconds, providing higher availability compared to current relays with greater simplicity. Calcite HA is enabled in all Calcite deployments.
For zero-downtime, NFDB is recommended.
Noswhere SmartCache
Relays are fixed in one location, but users can be anywhere.
Noswhere SmartCache is a CDN for relays that dynamically caches data on edge servers closest to you, allowing: - Multiple regions around the world - Improved throughput and performance - Faster loading times
routerd
routerd
is a custom load-balancer optimized for Nostr relays, integrated with SmartCache.routerd
is specifically integrated with NFDB and Calcite HA to provide fast failover and high performance.Ending notes
NFDB is planned to be deployed to Nostr.land in the coming weeks.
A lot more is to come. 👀️️️️️️

@ 86d4591f:a987c633
2025-04-27 22:12:47In our time, the contest for power no longer occurs only on battlefields or in parliaments—it plays out in prices, in language, in data. The house isn’t just stacking chips, it’s stacking the deck, cornering the very mechanisms by which society functions. Land, homes, energy, education, and even knowledge itself—all are subject to capture.
Is this a market failure, or a feature of the system? What does it look like when the relentless outcompeting of the many by the few is engineered through policy, shielded by narrative, and sanctified by language? Turns out it looks a lot like a squeeze. Not a short squeeze, mind you; more like The Great Squeeze—a persistent pressure that pushes working people to the margins, misdiagnosed and mislabeled as “inflation.”
Yes, inflation does occur. There are places and times when too much money chases too few goods. But is this one of them? Are prices rising because money is being printed—or because access is being restricted? If everyone is in debt—individuals, governments—then who holds the credit? And if inflation is always theft, who’s doing the stealing when wages stay flat, but asset prices soar?
No matter who it is, the fact remains: rather than address the root causes of system degradation—decades of financialization, institutional capture, and compounding inequality—central banks and their institutional allies have chosen a more subtle form of defense: narrative control. They tell us this is “normal.” That it’s inflation, and that inflation is your fault: your wages, your spending, your expectations. They hijack language. What was once considered progressive is now politicized, and what was once nuanced is often reduced to labels. A squeeze—deep and systemic—is redefined as a passing issue, obscuring the real, lasting pressures at play.
But in a digital age, truth is no longer scarce. Information is everywhere. We have access to more knowledge than any civilization before us. What we lack is not breadth—but depth. Not information, but conviction.
So how do we express this conviction? How do we resist tyranny—not with weapons, but with wisdom?
The answer may lie not in more experts or more arguments, but in markets of meaning.
Prediction Markets: A 21st Century Arsenal
1. The Wisdom of Crowds
A well-designed prediction market draws on the intelligence of thousands. Not in the chaotic swirl of social media noise, but through price discovery in belief. Here, truth isn’t shouted—it’s traded. When people put their money where their minds are, the collective signal becomes stronger than any headline.
2. Detecting Corruption Through Betting Patterns
Sports betting has exposed match-fixing before any referee or journalist. Irregular patterns in the odds don’t lie. If corruption leaves fingerprints, prediction markets can trace them—not just in games, but in elections, economic forecasts, and geopolitical risk. They are early warning systems for deceit.
3. Realigning the Incentives of Economists
Today’s economists often live in silos—publishing obscure models, advising hedge funds, and rarely facing consequences for being wrong. Prediction markets flip this dynamic: the best ideas win not through peer review, but public wagers. Incentives shift. The public gets access to live, evolving consensus, scored not in rhetoric but returns.
The Right to Bear Knowledge
The Second Amendment was written in an age of muskets, when tyranny came with boots and banners. Today, it comes with metrics and models. The new tyranny is epistemic—a war for control over what is known, and who gets to know it.
In this context, the right to bear arms must evolve into a right to bear knowledge.
Prediction markets are more than speculative tools. They are instruments of civic resistance. They give individuals power not just to observe the future, but to shape it—to challenge official narratives, expose falsehoods, and re-anchor the public’s sense of reality in evidence, not authority.
To bet on truth is not to gamble. It is to believe—publicly, financially—in what you can defend.
This is a novel case, but not a radical one. It simply returns us to the roots of democracy: a system built on informed citizens, capable of seeing through deception.
In a world where the elite privatize truth, prediction markets offer the public a chance to own it.
To bear knowledge is to be armed. To trade on truth is to be free.
Let the market speak— But let it be one we create.

2025-04-27 16:51:37Not everyone agrees or realizes that governments, corporations and banks are progressively infringing on our most basic rights and that we should fight back, if only with the right tools.
But I don’t believe in going out in the street to protest, hoping that the government will do something about it. I think that demanding from the State is actually giving it even more power. So what’s the solution?
I believe that Bitcoin is the best tool for individuals to reclaim their freedom and sovereignty.
By taking money out of the hands of central banks, 3-letter agencies and governments, we can reclaim complete control over our money, our life and our future.
I believe the world is facing a great threat. I’m not talking about global warming or climate change. I’m talking about a global political agenda, shared among Western countries’ governments, and focused on limiting individual freedom while increasing government control.
I believe our modern banking and financial systems are profoundly inegalitarian by nature, with the ability for a few elites to “print” money out of thin air and use it to follow their own agenda.
I believe our modern banking system was built like this on purpose. I do not consider the government’s and central banks’ money printing to be part of “how things normally work”, but rather to be a counterfeiting mechanism that they use for their own benefit.
For these reasons, I don’t believe that governments have the people’s best interest in mind. As a matter of fact, I rather think the opposite is true.
I believe this counterfeiting mechanism (or money printing) leads to financial servitude for the individuals, and systemic risk for human society as a whole.
I believe all the financial crises we witnessed since the beginning of the 20th century are directly linked to this counterfeiting mechanism, and that this system is now coming to an end.
As such, I believe most people grossly overlook the risks that are being taken with their money, whether it be sitting on a bank account or invested in financial markets.
Furthermore, I believe this flawed monetary system is in complete control of most people’s money, lives, and future.
But I believe there is an alternative to this flawed system: Bitcoin.
I believe Bitcoin is the best tool individuals can use to take back their freedom and resist government controlling their life.
And I believe you shouldn’t have to be tech-savvy to start using Bitcoin, but you definitely need to be freedom-minded.

2025-04-27 16:23:40Are you tired of having to trust banks and other financial institutions with your money? With Bitcoin, you can take control of your finances and be the sole custodian of your wealth. This is known as self-custody and it completely eliminates the need for third-party services, by receiving and storing your bitcoin securely in your own Bitcoin wallet. In this blog post, we will discuss what self-custody means, how it works, and the benefits and responsibilities associated with being in control of your own money.
What is Self-Custody?
Self-custody is simply the process of keeping your own private keys to your Bitcoin wallet, meaning you do not need a bank or any other third party to manage or access your Bitcoin funds; you are able to do all that yourself. This means that only you have full control over your money, allowing you to make transactions securely and safely without ever having to ask someone’s permission or worry about someone else mishandling or stealing it.
Who Is in Charge of My Bitcoin?
When using Bitcoin, you are in charge of your own Bitcoin wallet, which includes an unlimited amount of addresses that are used to receive Bitcoin, and a private key that is used to sign outbound transactions. The private key is literally the key to your Bitcoin wallet, as it can send Bitcoin to other addresses your don’t control. As such, it is imperative that it is kept safe and secure, accessible only by you. This is how ownership of Bitcoin is determined. If you share the private key to a wallet you control, you’re not the only one able to spend the Bitcoin inside the wallet anymore.
Benefits & Responsibilities
The most obvious benefit of self-custody is that no one else has control over your funds but you! That said, there are some important responsibilities that come with owning the keys to your Bitcoin wallet.
One responsibility that comes with being the only owner of your Bitcoin funds is making sure that your private key is safe from theft and loss. Fortunately, there are easy solutions available for securely storing Bitcoin keys, and seeking guidance from a knowledgeable source can be a great help if you’re not ready to take on this responsibility alone. A Bitcoin security expert can provide valuable insights and tools to help you ensure the safety and security of your funds.
Overall, Bitcoin gives immense power to individuals who want full control over their finances without relying on third parties like banks or payment processors. But taking ownership of your money also comes with certain responsibilities such as safeguarding your private keys; however these responsibilities pale in comparison when compared with the freedom and security granted by taking ownership of your money with Bitcoin! And with the right tools and guidance, using Bitcoin in a truly sovereign way can be way easier than you may imagine.

For traders, investors, and gamblers who are only interested in making a quick buck, Bitcoin is a new and volatile asset they can speculate on.
For individuals escaping tyranny or authoritarian regimes, Bitcoin is a way to move their wealth across borders and avoid it being seized by the government.
For people who live in inflation-ridden countries, Bitcoin is a way to protect their wealth against accelerating devaluation and avoid losing all their money to inflation.
For digital nomads, Bitcoin is a great way to easily earn money online, avoid paying high commission fees to payment processors (Paypal, Stripe, etc), and avoid high currency conversion fees while traveling.
As we can see, Bitcoin definitely is different things to different people. What we all agree on, though, is that Bitcoin is here to reject the status quo.
Bitcoin is the best tool out there for people who value individual freedom and seek more self-sovereignty to take control of their money, their lives, and their future.
What is Bitcoin to you?

– Friedrich Nietzsche
Der Mensch wächst nicht aus der Welt – er wird in sie geworfen, ohne Ursprung, ohne Auftrag, ohne Trost. Die Familie erscheint zuerst als Halt, doch sie ist oft der erste Spiegel, in dem man sich selbst nicht erkennt. Man nennt es Liebe, nennt es Bindung – aber vielleicht ist es nur die stille Einweisung in ein Gefängnis, dessen Mauern wie Umarmungen aussehen.
Kindheit, Freiheit, Einsamkeit
Das Kind ist nicht die Fortsetzung des Selbst, sondern der Beweis, dass auch das Chaos Nachwuchs hat. Es lacht, weil es noch nicht weiß, was Lachen kostet. Es fragt nicht, weil es noch nicht weiß, dass Fragen selten Antworten finden. Und doch ist es das Kind, das die Ordnung zum Wanken bringt – nicht durch Widerstand, sondern durch seine unbestechliche Gegenwärtigkeit.
Freiheit beginnt dort, wo man aufhört, sich retten zu lassen. Sie ist kein Zustand, sondern eine Haltung: die Weigerung, sich einer Bedeutung zu unterwerfen, die von außen kommt. Die Welt verlangt Funktion – das freie Leben verweigert sich der Funktion, nicht durch Aufstand, sondern durch Abwesenheit. Wer Sicherheit sucht, hat die Welt bereits verloren.
Einsamkeit ist kein Unglück – sie ist der Boden, auf dem das Selbst sich überhaupt erst spüren kann. Sie ist nicht leer, sondern ungeteilt. Was fehlt, ist nicht ein anderer Mensch, sondern die Illusion, dass Nähe uns ganz machen könnte. In der Tiefe des Alleinseins offenbart sich nicht Mangel, sondern Klarheit.
Das Nichts und die Möglichkeit des Lebens
Ein Kind stellt keine Fragen über das Nichts – es lebt in ihm, ohne es zu wissen. Der Erwachsene aber erkennt es, spürt es wie eine zweite Haut, die nicht abgelegt werden kann. Doch dieses Wissen ist keine Strafe. Es ist die Bedingung jeder echten Handlung. Wer das Nichts kennt, liebt nicht, um sich zu retten – sondern weil er weiß, dass nichts gerettet werden muss.
Ein Leben im Angesicht der Leere ist möglich. Nicht durch Verdrängung, sondern durch Durchschreiten. Die Rolle, die man spielt, wird erträglich, wenn man sie nicht mit Identität verwechselt. Die Arbeit, die man verrichtet, dient nicht mehr dem Fortschritt, sondern der Form – und vielleicht ist darin schon Würde genug.
Familie kann ein Nest sein – oder ein Netz. Es hält, oder es hält fest. Doch auch das Netz kann Heimat sein, wenn man nicht mehr erwartet, darin zu fliegen. Ein Kind zu begleiten heißt nicht, ihm Wahrheit zu geben, sondern ihm Raum zu lassen, seine eigene zu verwerfen.
Raum, Erlaubnis, Schönheit
Freiheit ist kein Ziel, sondern ein Aufhören. Wer nichts mehr will, dem kann nichts genommen werden. Wer das Nichts annimmt, dem begegnet keine Leere mehr – sondern Raum. In diesem Raum entsteht das, was nicht geplant ist, nicht beherrscht und nicht gezählt: der Moment, das Staunen, die Stille zwischen zwei Gedanken. Vielleicht ist genau das genug.
Man kann leben mit dem Nichts – wenn man nicht mehr verlangt, dass es Sinn macht. Man kann Vater sein, Mutter, Freund, Fremder – ohne sich zu verlieren. Man kann lachen, weinen, müde sein – ohne Trost zu brauchen. Denn wer dem Nichts ins Auge gesehen hat, der weiß: Alles ist bedeutungslos. Und genau deshalb ist alles erlaubt. Und manchmal, ganz selten, auch: schön.
