Project of the Day: Vinteum by @Vinteum_org
Who builds Bitcoin? Developers.
That's why Vinteum exists.
Based in Brazil, Vinteum is helping grow the next generation of Bitcoin contributors through developer funding, education, fellowships, research, workshops, and hacker houses.
Since 2022, they've supported work on Bitcoin Core, Lightning, BDK, Stratum V2, BTCPay Server, Floresta, and more.
A stronger Bitcoin needs more builders everywhere.
⚡ Support Vinteum and help fund the people building Bitcoin's future.

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.

Our fellow Vinicius has been exploring Bitcoin Core internals and just published a deep dive on what happens from the moment a transaction message reaches a node to when it enters the mempool.
If you’ve ever wanted to better understand transaction relay, validation, and mempool acceptance in Bitcoin Core, this is a great read:
From TX message to mempool
Our fellow Isaque has been diving deep into libsecp256k1 internals and wrote a deep dive on sipa’s very first commit to the project.
The post walks through the original C++ implementation of field element operations in the earliest days of libsecp256k1, unpacking how the code worked and the tradeoffs involved at the time.
If Bitcoin cryptography internals are your thing, this is a great read!
O PL 3066/2025 aprovado semana passada na Câmara e encaminhado para o Senado prevê prisão para quem desenvolver ou fornecer serviço de VPN. Não foi falta de aviso meu.

Bruno is one of the reasons Vinteum exists.
Helping him become a full-time Bitcoin developer was part of our founding vision, which later grew into a broader mission: creating a strong pipeline of Brazilian Bitcoin developers.
Btrust had a similar vision for Africa, later expanded it to the Global South, and became a major supporter of Vinteum’s work.
Bruno comes from a generation of Bitcoin developers that had to find their own way before organizations like ours existed. There are still many challenges ahead if we want open-source Bitcoin development to become a stable long-term career path.
We’re proud to see Bruno now helping guide that work at an even larger scale, and proud to share him with Btrust as a board member.

Dr. Edil Medeiros (@edil_medeiros), an associate professor at the University of Brasília, teaches a Bitcoin Protocol course, now in its second edition, with a third planned for 2026. The course combines low-level protocol mechanics with conceptual discussions, comparing Bitcoin to other cryptocurrencies. About 50 undergraduate students from engineering and computer science programs participate each year, covering topics from transaction semantics to cryptography, blocks, and proof-of-work.
Students engage through weekly lectures over 32 weeks, four homework/programming assignments, and a final project. Dr. Medeiros emphasizes understanding why Bitcoin works, not just how it works, preparing students for real-world technical challenges. The course is available online in Portuguese and English, including lecture recordings and MIT DCI materials.
Dr. Medeiros also serves as Head of Research at Vinteum, a nonprofit supporting open-source Bitcoin developers. He aims to build a Bitcoin protocol education pathway and establish a network monitoring lab to support global research initiatives. His teaching bridges practical development, research, and the open-source Bitcoin ecosystem.
Dr. Medeiros has agreed to speak at the BEI Annual Conference in Washington, DC, on July 31st. Register for the conference here: https://t.co/mNaHR1KNnd
