Last Saturday, BitDevs Lagos 🇳🇬 hosted another meetup, bringing the community together for a hands-on and insightful session. Peter introduced the Bitcoin Development Kit (BDK) and the BDK CLI tool, showing how these can be used to build Bitcoin applications, manage wallets, sync data, and handle transactions with ease. Chigala then dove into Bitcoin scripting. He explained what OP_Codes are, how Bitcoin scripts operate using a stack-based model, and demonstrated how to construct scripts using different OP_Codes.

), attendees had an interactive playground to experiment and test scripts themselves, making complex ideas more accessible. The meetup also marked Bitcoin Pizza Day, with plenty of pizza, great company, and vibrant conversations all around. 🍕 BitDevs Lagos remains one of the most active and longest-running BitDevs communities in Africa, thanks to the dedication of the organizers and the energy of everyone who attends. A huge thank you to Peter, Enyeazu, Tobechi and everyone who joined. See you at the next one!

BitDevs Uyo 🇳🇬 recently held its inaugural meetup, marking the latest BitDevs location to be supported by Btrust. 🚀 Participants explored the why behind Bitcoin, dove into hands-on wallet setups, shared sats with each other, and learned how wallets, transactions, and nodes work under the hood. The meetup also introduced everyone to the wider Builders community and shared opportunities to get involved in open source development. A huge thank you to the BitDevs Uyo organizers for a great start, and kudos to all the speakers who made the day so insightful.

We’re excited to announce our first Bitcoin Open Source Bootcamp! 🚀 The bootcamp officially kicks off today with our inaugural cohort selected from the recently completed Builders pathways: BOSS, Mastering Bitcoin and Bitcoin CLI cohorts. The Open Source Bootcamp is a 4-week intensive program designed to upskill developers and guide them toward making meaningful contributions to open-source Bitcoin projects. This cohort will spend the next month: • Setting up their Bitcoin development environments • Learning to navigate and review Bitcoin Core • Exploring real-world Bitcoin open-source projects • Making their first meaningful contributions to the ecosystem Participants will also receive weekly mentorship, feedback from experienced faculty, and guidance on preparing proposals for the @Btrust Starter Grant, which supports promising new contributors in continuing their open-source journey. The goal is to grow a diverse, capable pipeline of Bitcoin open-source developers committed to building long-term.

The first cohorts of the 2025 Btrust Builders Pathways have officially graduated. 🎉🎓 Over the past two months, developers from across Africa took part in Mastering Bitcoin and Learn Bitcoin from the Command Line. These programs were designed to build foundational Bitcoin knowledge and technical skills for open-source contribution.
