The home mining setup keeps getting better. Stratum V2 UI just landed on the Umbrel App Store - built by the Stratum V2 developers themselves! It provides a guided setup for pool mining, solo mining, and job declaration (your node picks the block template, not the pool). Plus one dashboard for hashrate, workers, and shares.
Stratum V2 UI is now live on the @umbrel App Store ☂️⛏️

Confirmo que há todos os indícios típicos de bloqueio nacional determinado pela Anatel no dia de hoje para api.github.com. Nas quartas-feiras, geralmente em dias de jogos de futebol, a agência de reúne com as maiores operadoras do país e determina o bloqueio de endereços utilizados pelos TV boxes. A lista de endereços bloqueados é mantido em sigilo pela agência, algo que tenho criticado em artigos, entrevistas e palestras. Os indícios são: 1) O fato de ocorrer numa quarta-feira e pelo relato desse internauta que me acionou, ontem o problema não ocorria. 2) O fato do IP 4.228.31.149 para qual aponta o FQDN api.github.com estar bloqueado somente na Claro, Vivo, Nio, Algar e TIM e *NÃO* em ISPs regionais conforme posso testar com o comando globalping. 3) O fato de outros endereços IP contidos no mesmo bloco /24 serem normalmente alcançáveis, o que exclui problemas de roteamento já que todos os IPs entre 4.228.31.1 e 4.228.31.255 necessariamente pertencem a mesma rota (vide exemplo 4.228.31.3). Recomendo que os afetados entrem em contato com seus provedores mostrando evidências coletadas a partir de sua casa ou empresa e exijam uma resposta do porquê não havia rota para 4.228.31.149 na noite de 10/06/26 enquanto para 4.228.31.3 há. Nesse thread a seguir, colocarei algumas informações úteis sobre o problema.

está resolvendo por 4.228.31.149, e não bate rota, mais um exemplo do que o @ayubio vem comentando há tempos. Imagino ser o bloqueio de outro *.github.io nacionalmente que comprometeu o api.github.com junto 🤡 Tentei pela VIVO, claro, Oracle, mas só vai com VPN de Miami

The first milestone is complete. DOOM now runs on the BMM101. Next up: Mujina and a pruned Bitcoin node.

Almost 10 years ago, Lucas Ferreira (@lucasdcf), co-founder of @Vinteum_org, turned to Bitcoin in an effort to avoid a pyramid scheme. He'd just graduated from university with a degree in anthropology. Wanting to have a social impact, he considered pursuing a PhD. However, he decided against it when he figured out there wasn't space in academia for all of the students entering the PhD program to become professors. "It was actually a pyramid scheme," Ferreira said about academia. He found Bitcoin soon after coming to this realization and quickly got involved in the space. And his involvement ever since has not only been a boon for Brazilian 🇧🇷 Bitcoin developers but for the Bitcoin space at large. I documented Lucas's incredible contributions in the piece below. Enjoy!

What does it take to build a truly global Bitcoin protocol? @lucasdcf, co-founder of @Vinteum_org, has spent years making space for Brazilian developers in the Bitcoin open-source ecosystem. Through grants, education programs, and @casavinteum, Vinteum has helped 15 developers land full-time roles at projects like @bitcoindevkit, @StratumV2, and @Blockstream.

Mining decentralization is a big priority for us too. We’re funding @plebhash’s work on Stratum V2, @johnnyasantos’ work on P2Pool V2, and training fellows like @jayrmotta on Mujina and @VCestarii on IPC work that interfaces with mining projects. Looking forward to collaborating with Localhost in yet another area.
1/2 Three months ago we announced the resurrection of FIBRE. Today, we take our next step. Localhost Research has established a Mining Unit: a group of contributors working full time on reducing centralization pressures in Bitcoin mining.

Great to see @StratumV2 support landing in BitAxe beta firmware. If you want to help test it before it becomes available for everyone: 1. Download and update github.com/bitaxeorg/ESP-Min… 2. Point miner to BlitzPool or use SV2 UI.

Had to reflect over the past two years, as it's been an incredible journey. Affordable mining hardware has been no easy task, but with a lot of effort and discipline, we've reached an amazing milestone we're excited to share with you all.
