A serious website was long overdue. We redesigned vinteum.org to better tell the story of what we’ve been building: funding, training, and supporting open-source Bitcoin developers and researchers in Brazil. Check it out: vinteum.org
Too few people understand the bdk_chain crate deeply, so @_oleonardolima hosted a deep dive at Casa21 with our fellows and grantees. We went through how @bitcoindevkit models chain data, transaction graphs, anchors, checkpoints, spks, seen-at timestamps, and the indexing logic that lets wallets reason about transactions without depending on a single backend. These sessions are part of our monthly in-person technical deep dives, where we fly Vinteum fellows and grantees to São Paulo for a week of focused work: reading specs, reviewing PRs, studying architectures, finding bugs, and contributing together. In-person protocol work is powerful.
Fuzzamoto deep dive at @casavinteum cc @dergoegge
Every month, we fly our fellows and grantees to @casavinteum in São Paulo for a week with our Head of Research, @edil_medeiros, and Head of Engineering, @brrrunog. We spend the week doing deep dives into BIPs, reviewing PRs together, and discussing broader protocol topics. It’s been incredibly productive: we’ve found gaps and suggested improvements to BIP specifications, discovered bugs in important libraries, and generated new ideas for patches and collaboration. In-person work is powerful.
