Rust 🦀 is quickly becoming one of the most important languages in the Bitcoin ecosystem. From wallet libraries to Lightning implementations, more projects are adopting Rust for its safety, performance, and reliability, traits that align perfectly with Bitcoin’s need for secure and predictable software. At the 2025 #BtrustDeveloperDay, Jamal ERRAKIBI explored this growing trend in his talk, breaking down what makes Rust different from other languages and why it’s reshaping how Bitcoin software is built. 🎥 Watch the session recording here: https://www.youtube.com/live/bDxhY5p1yKQ?t=5145s In our latest blog, Jamal expands on that talk, diving deeper into how Rust’s memory safety, high performance, and strong type system power projects like rust-bitcoin, BDK, rust-lightning, and Fedimint. He also shares lessons from contributing to Rust-Bitcoin and practical advice for developers looking to get started or contribute. 👉 Read the full article here:

Why Rust Is Becoming Essential in Bitcoin

We recently had the pleasure of sponsoring and being part of the just concluded @Adopting Bitcoin Cape Town 🇿🇦 conference. Things kicked off on Thursday with the Bitcoin Circular Economy Summit, followed by the pre-conference hangout. It was a great chance to meet people, network, and enjoy some fun activities like sim golf ⛳ before the main event began. On day 1, @npub1zm2d...f260, a Btrust developer grantee working on Stratum V2, presented a session on mining decentralization. He broke things down from the basics all the way to the technical details, showing why mining pool centralization can become a censorship risk. He also shared how Stratum V2 helps miners choose their own transactions, making Bitcoin more secure and decentralized. On day 2, @Sharon Murugi, our communications lead spoke about what it takes to support and sustain open-source development in Africa and the Global South. She reminded everyone that behind Bitcoin is a strong human layer, consisting of developers, reviewers, maintainers, and community builders whose work keeps the network running and growing. She also shared how developers help turn Bitcoin from just a protocol into tools people actually use every day, like wallets, self-custody solutions, and payment infrastructure. That’s why decentralization shouldn’t stop at the code. We need builders from more places, especially those who understand local challenges, helping shape the tools that will bring Bitcoin to the next billion users. We’re proud to support this work by creating more sustainable paths for contributors and helping strengthen the ecosystem. One of the coolest parts of the conference was seeing bitcoin used in real life. We were able to buy coffee using bitcoin, powered by @BTCPay Server, one of the open-source projects helping make bitcoin payments possible. There was also a dedicated workshop space where builders got to share what they’re working on. It was exciting to see solutions being built from real local problems, and we loved connecting with the community and exploring new partnerships. A big thank you to the organizers and everyone involved for putting together such an amazing experience.

Over the past few years, BitDevs communities across Africa have been building technical spaces rooted in learning, openness, and collaboration. Today, we’re sharing the guide that brings those lessons together. The BitDevs Playbook v0.1.0 is the first public release of a practical, open‑source guide for building and sustaining Bitcoin‑only technical communities across the Global South. Grounded in real experience from BitDevs communities across Africa, it explains what BitDevs is, why the model works, and how to start, run, and sustain high‑quality technical meetups with shared standards around learning, privacy, neutrality, and non‑commercial focus. In the accompanying blog, we reflect on why BitDevs matters, how the model creates space for open discussion and open‑source contribution, and how communities across Africa have grown beyond monthly meetups into hubs of ongoing learning and collaboration:

Introducing the BitDevs Playbook

A practical guide for building and sustaining Bitcoin-only technical communities across the Global South.

Many of these communities, supported by organizations like Btrust and @Bitcoin Zambia, have helped members access advanced programs such as Chaincode Labs’ BOSS program and the @Btrust Builders pathways. Some members have gone on to start careers in Bitcoin open‑source development, supported by organizations like Btrust and the @HRF, while others have gone on to build products and projects of their own. The Playbook is fully open‑source and community‑driven. It covers the full lifecycle of a BitDevs location, from assessing local interest and hosting a first meetup, to maintaining quality, handling challenges, and even responsibly pausing or closing a location when needed. It’s designed for organizers, sponsors, contributors, and anyone who cares about building credible, technically grounded Bitcoin communities. Huge thanks to Stephanie Titcombe for authoring the playbook, and @Abubakar Nur Khalil, Simon from BitDevsNBO, and Tobechi Chukwuleta for shaping this first release with their experience and feedback. 📘 Explore the Playbook to learn how to use it and contribute your insights here:

We’re deeply grateful to everyone who joined us, and we’re looking forward to the work ahead of us.

"This is my first time outside India 🇮🇳 to an international bitcoin conference or gathering. The bar has been set really high for me now." Paperpsych from @npub1m495...u22l. Day two of the 2025 #BtrustGathering built beautifully on the momentum from day one, diving deeper into collective learning and collaboration.

Day two of the #BtrustGathering began with an opening plenary, where participants shared takeaways and reflections from day one and discussed what to look forward to. The morning continued with a session on rethinking developer funding and support, facilitated by Kelvin Isievwore. This session explored how developers across the Global South are supported, financially and beyond, through existing funding mechanisms, mentorship, travel opportunities, and access to tools. We brainstormed practical ways to build fairer, more sustainable models that empower developers long‑term. Next came an insightful session on finding your lane and building credibility in open-source, by Edil Medeiros. This conversation encouraged developers to navigate their open‑source development journeys with authenticity, confidence, and resilience. We then had a thought‑provoking panel on AI, facilitated by Kelvin Isievwore and featuring Abubakar Nur Khalil, Raj, Bruno Ely Reis Garcia, Federico Zupicich, and Leonardo L. The panel unpacked how AI is reshaping open‑source contributions, from enhancing reviews and documentation to transforming developer workflows, and discussed both the opportunities and trade‑offs it brings to Bitcoin development. After a productive morning of discussions and learning, we took a break to take group photos and lunch. In the afternoon we moved into the mapping Global South FOSS priorities workshop, facilitated by Abubakar Nur Khalil. Participants worked collaboratively to define shared priorities, align regional outcomes, and begin drafting a collective 2026 roadmap for open‑source growth across the region. We closed the day, and the gathering, with a heart‑to‑heart fireside chat on lessons from the field. This conversation, featuring Kelvin Isievwore, Nymius, Abubakar Sadiq Ismail, Stratosphere and Marcello Pinsdorf, highlighted real‑world experiences, challenges, and lessons from the community, with candid reflections on sustaining motivation, balancing life and contribution, and navigating burnout. With the Gathering coming to a close, participants left inspired and energized, ready to carry the spirit of collaboration, learning, and open‑source excellence into the year ahead.

Day one of the #BtrustGathering began with an engaging opening plenary by Stephanie Titcombe, followed by the state of Btrust address from our CEO, @Abubakar Nur Khalil, who shared a thoughtful year‑in‑review, key milestones from 2025, and the outlook for 2026. The morning continued with the 2025 program reports, where @Btrust Builders, @npub13s0k...5g70, @npub1m495...u22l, and Libreria de Satoshi presented updates on their work, growth, and the impact they’ve created in supporting open‑source Bitcoin development across the Global South. In the afternoon, participants joined cross‑organization working groups to explore opportunities for collaboration on joint programs, developer connectivity, localization, and technical cooperation. Discussions also covered shared initiatives, developer exchange and communication, grants and sustainability, as well as community growth, storytelling, and brand alignment. These sessions were energetic and idea‑driven, with groups sharing thoughtful outputs that reflected the strength of cross‑community collaboration. The day captured the essence of what the gathering stands for; connection, transparency, and collective progress. It was a powerful reminder of how much can be achieved when builders from across the Global South come together to advance open‑source Bitcoin development.

Highlights from day one of the 2025 #BtrustGathering 🎉 Day one of set the tone for the work that's to come in 2026. It was a day focused on sharing progress, celebrating program highlights, and reflecting on our collective impact across the ecosystem.
