Our team will be be attending and speaking at this year’s edition of Bitcoin Amsterdam 🇳🇱. @npub13e6q...md43 brings together developers, entrepreneurs, researchers, investors, and community builders from across the global bitcoin ecosystem to exchange ideas, explore emerging developments, and discuss the future of bitcoin. Tomorrow, @Abubakar Nur Khalil and Abubakar Sadiq Ismail will take the stage alongside Rob Netzke for a discussion on getting started in Bitcoin open-source development. Later in the day, Abubakar Nur Khalil will take the Treasury Stage to explore the priorities, principles, and trade-offs shaping bitcoin’s future, from individual sovereignty to mainstream adoption, and whether the community needs a shared vision or room for disagreement. We’re looking forward to meeting fellow builders and members of the wider Bitcoin community, exchanging ideas, and exploring opportunities to build together. See you there!

It’s easy to tell yourself you need to learn a little more before you’re ready. One more course, one more book, then you’ll start. Nkatha Kaburu knows that feeling. She was learning, building, and showing up in Bitcoin communities, but contributing to open source still felt like something she needed to prepare for. Things began to change when she picked an issue, asked questions, and worked through the feedback. Her first contribution took two months, and helped her see that she could learn by doing. In our latest grantee spotlight, Nkatha shares her journey to contributing to Braidpool ⛏️ and becoming a Btrust grantee, alongside the people and lessons that helped her keep going. If you’ve been waiting to feel ready, her story might be the encouragement you need to take that first step. Read it here:

Bitcoin’s code is open to everyone. But access to the code is not the same as an opportunity to contribute. Technical education, mentorship, supportive communities, and the time and funding to keep building all shape who can participate, and sustain their work. In our latest article, we explore why decentralizing Bitcoin development takes more than geographic diversity, and how Btrust supports pathways for more people, experiences, and perspectives to help shape the technology.

As AI coding tools become more widely used, generating code that looks ready to merge is easier than ever: passing tests, a polished PR description, and a green CI run. But none of those guarantees correctness, and in Bitcoin, where mistakes can have irreversible consequences, that distinction matters. At @btcplusplus Nairobi 🇰🇪, our Head of Engineering, Kelvin Isievwore, discussed responsible AI use in Bitcoin open-source development; where it can help contributors, where it falls short, and why understanding and verifying the code you submit remains your responsibility. Watch the full session:

Over the past two editions, #BtrustDeveloperDay has brought together developers, designers, contributors, and builders from across the Bitcoin ecosystem. Unfortunately, we won’t be hosting the event this year. We know many of you were looking forward to gathering again, and we’ll miss the opportunity to learn, connect, and build together. We’re using this time to listen, reflect, and prepare for a bigger next chapter in 2027. Thank you to everyone who has joined us, contributed, spoken, volunteered, and built alongside the community so far. We can’t wait to welcome you back in 2027. More details are coming soon. Watch this space.

We are excited to be attending and speaking at @npub17yqg...5269 🎉 TABConf is a conference focused on Bitcoin, bringing together developers, researchers, and open-source contributors to share ideas, explore new technologies, and collaborate on building Bitcoin’s future. Open-source development is at the heart of Bitcoin, and we’re looking forward to contributing to conversations on the tools, people, and communities shaping its ecosystem. Catch our Head of Engineering, Kelvin Isievwore, and Btrust developer grantee, Itoro Ukpong Oluwasegun, on the main stage today. 🕦 11:30 am - Beyond the FFI Frontier: What It Actually Takes to Expose Rust Bitcoin Across Multiple Languages Itoro will unpack the engineering challenges of making Rust-based Bitcoin wallet logic accessible across languages like Swift, Kotlin, Python, and Dart, including how developers can use UniFFI to build and distribute cross-platform SDKs 🕛 11:45 am - A New Centre of Gravity: Bitcoin Open Source Development in the Global South Kelvin will explore how Bitcoin open-source development is becoming more geographically decentralized, with contributors in the Global Majority building communities, organizing conferences, mentoring developers, and becoming maintainers of open-source projects. We’re looking forward to meeting fellow developers, open-source contributors, and members of the Bitcoin community, exchanging ideas, and exploring opportunities to build together. See you there!

What does it take to build an ecosystem where developers in the Global Majority can do more than participate in Bitcoin, but help shape where it goes next? In the final episode of season one of Btrust in Focus, Paul Eke sits down with Abubakar Nur Khalil, CEO of Btrust, to talk about the thinking behind Btrust, how the organization has evolved, and what it takes to build the foundations for a stronger Bitcoin ecosystem in the Global Majority. They discuss the challenges of creating pathways for developers, building a team around a shared mission, and why Btrust sees its role as creating the conditions for others to build. Abubakar also looks ahead at what Btrust is working towards: a stronger Bitcoin ecosystem where more developers from the Global Majority have the opportunity to build for the world, while Btrust continues to strengthen the foundations that make that possible.

What happens when learning Bitcoin stops being just about understanding the technology and starts becoming about building something with it? In the latest episode of Btrust in Focus, Paul Eke sits with Fidel Otieno, founder of @npub1pcwq...eat5, to talk about his path into Bitcoin development and the experiences that shaped his approach to building. They discuss the challenges of learning Bitcoin as a developer, the programmes and communities that helped Fidel deepen his technical understanding, and how those experiences eventually led to Bitika, a platform making it easier for people in Kenya 🇰🇪 to access Bitcoin through M-Pesa and Lightning⚡. The conversation also explores Fidel's vision for building useful Bitcoin products in Africa and his advice to developers who have ideas but are still waiting for the right moment to act on them. Watch the full episode here:

Open-source Bitcoin development requires something most engineers can't easily give it: sustained, uninterrupted time. For many developers, contributing to Bitcoin infrastructure has to compete with the job that pays the bills. Reading unfamiliar codebases, working through reviews, staying with a problem across multiple iterations, all of that takes a kind of focus that is hard to find in the margins of a full-time job, and this is why funding exists. In 2025, Btrust awarded more than $2 million in grants, with 39.7% going directly to developers working on open-source Bitcoin infrastructure. Across the year, 18 grantees contributed to 15 open-source projects, collectively merging 222 pull requests and making 475 code reviews across the Bitcoin stack. However, funding is only useful if developers know how to access it. That means understanding what kinds of work can be supported, what funders are actually evaluating when they read an application, and which program fits where you are right now in your contribution journey. We put together a practical guide that answers all of it. It covers what Bitcoin open-source funding looks like, the difference between grants, fellowships, cohorts and project funding, what to have ready before you apply, what makes an application stand out, and where to start if you are still building your contribution record. If you have been thinking about making the transition from part-time contributor to full-time open-source developer, this is where to start. Read the full guide here:

Last week, we had the pleasure of sponsoring and presenting at the Genesis Workshop hosted by OSGuild in Mauritius 🇲🇺. Two of our developer grantees, @Chuks and @npub1zm2d...f260, joined the workshop to share their knowledge and experiences with the local community. On day 1, Sy introduced participants to the fundamentals of bitcoin, covering the basics of how it works, and mining ⛏️. Chuks ended the day with a session on the Lightning Network⚡, explaining how it enables fast, low-cost bitcoin payments and the technology that makes it possible. On day 2, they joined a panel discussion to share their journeys into Bitcoin open-source development, offering practical advice and encouragement to developers looking to contribute to the ecosystem. Across the two days, participants took part in technical presentations, thoughtful discussions, and the interactive @npub1vmpf...xhm7 LARP, making for an engaging and collaborative learning experience. A huge thank you to Sadiq Rabiu and the OSGuild team for organizing such a fantastic event. We're grateful to have been part of it and look forward to supporting more initiatives that help grow the Bitcoin open-source community.

At Btrust, we believe a stronger Bitcoin open-source ecosystem starts with better developer education. Developers need structured learning, mentors, and communities that help them grow from learners into contributors.

Lightning⚡ can make bitcoin payments fast and low cost, but building a Lightning-enabled app from scratch can still feel like a lot. There are channels to open, liquidity to manage, invoices to create, payments to track, and events to handle. LDK Node makes that path more practical by packaging the hard infrastructure choices into a smaller, production-ready API. In our latest blog, 👩‍💻 Rita Anene walks through building a working Lightning node in Rust 🦀, step by step: connecting to a peer, opening a channel, handling the ChannelReady event, receiving and sending BOLT11 payments, creating and paying BOLT12 offers, and sending a spontaneous payment without an invoice. It is a hands-on starting point for developers who understand Bitcoin and want to begin building on Lightning, without needing to learn every layer of the protocol first. Read the full article here:
