@iamflops
Code, math and physics are my passion ∑ Working as a Bitcoin open source developer
We're excited to welcome @iamflops as a Vinteum grantee! He'll be working on expanding Bitcoinfuzz's test coverage for the Lightning Network, improving interoperability, uncovering edge cases, and making Bitcoin more robust. Read more here: medium.com/vinteum-org/fu…
1/ We bought a Dell PowerEdge R730 for Casa21: 🔸 56 cores 🔸 128GB RAM 🔸 8x 1.2TB 10K SAS drives to run some serious Bitcoin infra — and we’re very proud of it! Big thanks to @luisschwab_, @ngoline, @jaoleall, and @_oleonardolima for leading the effort 🫡🧡
Two more trophies for bitcoinfuzz! 🏆 Two bugs on LND on bolt11 implementation: github.com/lightningnetwo… github.com/lightningnetwo… Kudos to @iamflops for working on this target and finding them.
New bugs/inconsistencies found by bitcoinfuzz: panic when parsing a PSBT on btcd, core lightning not validating pub keys in routing hints, overflow on lnd, and more… github.com/bitcoinfuzz/bi…
All of the OP_RETURN drama just reinforces for me how few people actually understand how Bitcoin works at a fundamental level. Anyone telling you that you can filter out arbitrary data at the mempool policy level are either malicious or misinformed, it simply is not feasible.…
Quer entender como o Bitcoin e a Lightning Network funcionam por baixo dos panos? Os Mastering Seminars vão te guiar pelos fundamentos técnicos, com base nos livros “Mastering Bitcoin” e “Mastering the Lightning Network”. Vagas limitadas! Link pra inscrições na bio!
Thrilled to be part of this amazing opportunity working on Bitcoin open source! The challenges inspire me, and I'm grateful to @Vinteum_org for support. Contributing to tech that can change the world is a privilege I never expected but absolutely love!
🚀📢 Announcing the new Vinteum Fellows! 📢🚀 At @Vinteum_org, our mission is to accelerate open-source Bitcoin development, and the Fellowship is a key part of that effort. Meet the first cohort and the projects they’ll be working on over the next 6 months! 🧵👇

Uma seed de 12 palavras tem 128 bits de entropia, ou seja, 2¹²⁸ combinações, um número gigantesco. Mesmo com computação quântica (algoritmo de Grover), o máximo que se conseguiria seria reduzir isso para 2⁶⁴ tentativas, ainda impraticável. Boa sorte. Mais fácil minerar.
Evitem usar só 12 palavras e carteira sem passphrase. Do msm jeito q eu fiz esse bruteforce em 2 minutos, tem pessoas mto mais inteligentes q eu trabalhando nisso. #Bitcoin
bitcoinfuzz now does differential fuzzing of LN impls (kudos to @maicomjt, @iamflops and team). It started with BOLT11 (invoice decode) and it just found an inconsistency when handling multiple fallback addresses!
After our in-person residency, 22 Bitcoin Dev Launchpad participants flew to @btcplusplus! 🚀 We're very proud of them! 🔥 9/26 hackathon projects had our BDL participants, and 5/26 came from our broader community in Brazil (Casa21, BitDevs, past hackathons & other initiatives)
Ontem, recebemos uma visita muito especial no BDL: @AkitaOnRails! Akita foi fundamental na formação profissional de muitos de nossos alunos — e sua recomendação trouxe 90% das inscrições para o programa. Uma grande honra tê-lo conosco para conhecer de perto nosso trabalho!
Pq a #bolhadev não fala sobre Bitcoin? Bitcoin é um projeto open source que precisa de mais devs.
I think today was one of my best days. Everything I did was not in vain. I am happy to say that I will be in the bitcoin++ Let's build a better world!
