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.
