Congrats, @iamflops! Well deserved!
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…

7/ Last but not least: @brrrunog and @iamflops will be using 40GB of RAM on this machine to run differential fuzzing across Bitcoin and Lightning implementations using Bitcoinfuzz. Let’s break stuff before prod does 🧨
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 🫡🧡
Running some juicy infra at our hackerhouse 🧃 Beyond public services, our grantees and fellows get personal VMs for dev work — plus infra for fuzzing, testing, and network monitoring to support research and real contributions.

Nah these Brazilian teams came to play. Wow. We gotta put some respect in the Brazilian league.
Vinteum’s founder @lucasdcf took the Expo Stage at @BTCPrague to remind us: Bitcoin won’t succeed on its own. It needs builders of all kinds — devs, designers, educators, advocates, and more. Bitcoin is not inevitable — it needs you.
