Our fellow Vinicius has been exploring Bitcoin Core internals and just published a deep dive on what happens from the moment a transaction message reaches a node to when it enters the mempool.
If you’ve ever wanted to better understand transaction relay, validation, and mempool acceptance in Bitcoin Core, this is a great read:
From TX message to mempool
I made a new blog post: what Bitcoin Core does when a peer sends a TX message tracing the full path from message to the mempool.

Mining decentralization is a big priority for us too. We’re funding @plebhash’s work on Stratum V2, @johnnyasantos’ work on P2Pool V2, and training fellows like @jayrmotta on Mujina and @VCestarii on IPC work that interfaces with mining projects. Looking forward to collaborating with Localhost in yet another area.
I measured block propagation and validation duration during the slow-to-validate blocks on Signet event last week.

The median listening node saw a 160x slowdown in block validation speed. Validation durations for median node: 176ms -> 20s.
A verdadeira descentralização exige acessibilidade. 🌲⚙️
Com o @getfloresta e o motor SwiftSync, rodar um Full Node de Bitcoin deixa de ser um privilégio de quem tem máquinas potentes.
Isso é soberania. 🇧🇷
Last week’s Bitcoin++ Exploits Edition in Floripa was packed. ⚡
Teams worked on fuzzing, monitoring, and bug hunting across open source Bitcoin projects.
To close the day, Vinteum hosted everyone for a karaoke night (classic @lucasdcf). 🎤🚀
First day of @btcplusplus Exploits Edition in Florianópolis.
Vinteum was proud to be the main sponsor of this deeply technical gathering, bringing developers together to explore historical bugs, attack surfaces, and ways to make Bitcoin more robust.
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 🧵👇
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?
