Next @rafaelturon explores how Bitcoin multisig coordination can be decentralized using end-to-end encrypted messages across independent Nostr relays, without trusted intermediaries learning what is being signed. Building on projects like Joinstr and Smart Vaults, he argues that securing the keys is only half the battle. Even the most sophisticated M-of-N multisig setup is only as resilient as the communication infrastructure connecting its signers.

More than a year after our first Bitcoin Dev Launchpad cohort, the paths are clearer. Alumni are now working across Bitcoin open source through independent grants, full-time engineering roles, and long-term contributions. Here’s where BDL1 took them ↓ vinteum.org/blog/bitcoin-dev…

Our residency is underway. 25 students are going through the in-person phase of our Bitcoin Developer Launchpad, and over these days we’re diving deep into secp, mining, taproot channels, fuzzing, monitoring, Bitcoin Core coding exercises, IPC, Utreexo & SwiftSync, PGP and web of trust, the four generations of Ark design, and Warnet’s Battle of Galen Erso, with sessions led by @edil_medeiros, @plebhash, @pins_btc, @brrrunog, @0xB10C, @danielabrozzoni, Sjors Provoost, @Erik17192799, @jaoNoctus and @stevenroose. We’re also running PR Review Clubs on Core and BDK with @brrrunog and @_oleonardolima, while participants present 15-minute talks on topics like MuSig2, cluster mempool, silent payments, BIP 324, libbitcoinkernel and mevpool. On top of that, there’s a TABConf-style capture-the-flag challenge by @jaoNoctus and a very challenging multisig signet + p2p + mining exercise by Matthew Zipkin. We’re sharing two days with @libdesatoshi so both residencies can interact, and we’ll wrap everything up next week at @btcplusplus Exploits Edition, which we’re co-hosting and sponsoring. Looking forward to the results.

That was fun! We saw our residents going overnight trying to crack the cashu challenge (take a look @callebtc) or trying to sign a musig2 tx. H/t to @jaonoctus for his brilliant challenge! @miketwenty1 are you proud of your padawan?
As a Developer Advocate at @Vinteum_org, I help empower builders through education and practical learning experiences. I'm deeply passionate about solving challenges. I'm inspired by the puzzles I've worked through, by the clever challenges I've seen @narcelio crack (specially the ones by Mica/Walltime), and by the ones @tidwell creates for @tabconf. Seeing how a well designed challenge can push people to think differently and explore deeper layers motivated me to create another one (the fourth I've designed) for the BDL 2025 cohort. This one is rooted in LOTR elements: hidden messages, "precious" secrets, deceptive paths, and clues scattered like fragments of an ancient map. Participants must look beyond what is obvious, question what they see, and connect subtle hints embedded in the story and visuals. They managed to solve it in less than 3 days! Let's break it down 🧵👇
