Btrust

2025 was a defining year for Btrust.

After several years of experimentation and learning alongside communities, this year marked the beginning of a more structured phase focused on strengthening the systems that support Bitcoin open‑source developers across the Global Majority.

Here’s a look at what we built and learnt throughout the year: x.com/i/status/20422…

How do developers find bugs they don’t already know to look for?

Even when software passes its tests, an unusual input can expose a problem no one anticipated. Fuzz testing helps developers explore those possibilities by repeatedly generating and modifying inputs, looking for crashes, errors, and broken assumptions.

In our latest article, Btrust grantee @_frankomosh shares insights from his fuzz testing work, helping explain how the process works, why it matters for Bitcoin, and what it takes to turn a failure into a useful finding.

We’re on at the proof of work stage at @bitcoinconfams.📍

@ihate1999, @sadeeq_ismaela, and Rob Netzke are discussing how newcomers can find their way into Bitcoin open-source development, including the different skills, communities, mentorship opportunities, and practical pathways that can help turn curiosity into meaningful contributions.

At Btrust, we believe the future of Bitcoin open-source development depends on strong local communities where developers can learn, question and build together. BitDevs is one such community, and its latest Lagos meetup brought together developers, researchers and Bitcoin enthusiasts for a discussion led by @TChileta, Lead Organizer of @BitDevsLagos

The session examined stranded miners and the economics of Bitcoin mining before turning to AI attacks in Bitcoin. As with every BitDevs meetup, the discussion was shaped as much by the questions from the room as by the presentation itself.
