“The ₿OSS program was intense, fast‑paced, and fun. It changed my life.” Chuks Meet Chuks, a software engineer from Lagos 🇳🇬, one of the outstanding 2025 ₿OSS alumni whose journey embodies what the program is all about: growth, contribution, and impact. With over eight years of experience building and maintaining complex software systems, Chuks joined the BOSS Challenge eager to expand his understanding of Bitcoin and Lightning Network development. The program helped him dive deep into open‑source collaboration, system architecture, and critical protocol work, areas that now define his career. Since graduating, Chuks has contributed extensively to key Bitcoin and Lightning open‑source projects, including Lightning Dev Kit (LDK), LDK‑Node, and SimLN, where his improvements have strengthened code reliability, testing infrastructure, and payment protocols. He’s also building PeepsWire, a Lightning‑powered video calling application showcasing how Bitcoin can drive real‑world innovation. Today, Chuks continues to work full‑time in the ecosystem through the @Btrust starter grant, accelerating his work on BIP 353 integration (Human‑Readable payment addresses) and improving simulation tools that help developers test and advance the Lightning Network. Chuks’ journey started with the ₿OSS program, and now continues through funded open‑source work that’s shaping the future of Bitcoin engineering. Ready to begin your open‑source journey? Applications for the 2026 ₿OSS Challenge, by Chaincode Labs, are open. This structured, hands‑on program helps new developers take their first steps into Bitcoin open‑source, gain mentorship, and build a path toward sustainable, funded careers, just like Chuks did. 🗓️ Applications close: December 31st, 2025 🗓️ Program starts: Week of January 12th, 2026 📝 Apply for the 2026 cohort:

Meet Shammah Agwor, one of the 2025 BOSS alumni, a passionate software engineer from Port Harcourt, Nigeria 🇳🇬, who has steadily grown into an active Bitcoin open‑source contributor. Shammah’s journey began long before joining the BOSS program. With a background in security engineering and years of experience in backend systems, he discovered his true calling in Bitcoin open‑source development. Through the program, he deepened his work in Rust‑Payjoin, a privacy‑enhancing Bitcoin project focused on improving transaction privacy and disrupting common input ownership heuristics. Today, Shammah continues to contribute full‑time to Bitcoin open-source. His work on Rust‑Payjoin includes major improvements like metrics collection for adoption tracking, caching mechanisms for performance, and better code structure for maintainability, all critical to strengthening Bitcoin’s privacy layer and reliability. Shammah’s ongoing impact as a @Btrust‑funded grantee reflects what’s possible for African developers who take that first step into the ₿OSS ecosystem. Ready to start your own Bitcoin open‑source journey? Applications are now open for the 2026 ₿OSS Challenge, in partnership with Chaincode Labs. This is your chance to gain hands‑on experience, mentorship, and a pathway into the global Bitcoin open‑source community, just like Shammah did. 🔗 Learn more about the program:

A week after the @Africa Bitcoin Conference, we’re still feeling the excitement. 🙌🎉 This year was especially meaningful as we were recognized as the African Bitcoin Project of the Year, a huge honor we're grateful to the @African Bitcoiners team for. Some of our community members also hosted workshops, we connected with builders from across the world, and the sessions throughout the conference were incredibly insightful. The conversations opened up fresh perspectives and sparked exciting ideas. We’re grateful to @Btrust for the chance to be part of it, and we’re already looking forward to the next one. Till then, we keep building 🚀 #ABC25 #ABC2025

Thank you so much! This means the world to us.🥹🧡 From the bottom of our hearts, we're grateful. To our builders, faculty, chaperones, mentors, and the entire community, this award is yours. We wouldn't have achieved this without your dedication, belief, and hard work. We're honoured to keep building for, and with, all of you. 💪🚀 View quoted note →

We're super excited to announce the graduates of our first-ever Rust for Bitcoiners and Language Clubs cohorts. 🥳🎉 These talented developers from over 15 countries dedicated themselves to acquiring the core skills needed for open-source Bitcoin projects. We've captured all the highlights, insights from the cohorts, and what's next in our full recap, which you can read here:

Kickstart Your Bitcoin Developer Career

Do you get frustrated with how today’s digital payments seem to demand a tradeoff; forcing you to give up your privacy, pay high fees, or worry about data breaches every time you accept a transaction? Many merchants and shoppers feel boxed in by systems that leave a trail of personal information behind with every tap or scan, making privacy feel like a thing of the past. But what if you didn’t have to choose between fast, modern payments and the anonymity of cash? In our latest blog, Tobechi, a @Btrust grantee, introduces Cashu, a digital cash protocol that lets merchants enjoy the best of both worlds. With Cashu, you can accept Bitcoin-backed payments instantly and privately, without exposing customer data or risking chargebacks. The blog breaks down exactly how Cashu works, explaining the roles of tokens, wallets, and mints in this ecosystem. He explores ways businesses can benefit from Cashu. You’ll also find a simple guide on how to start accepting Cashu payments using BTCPay Server so you can quickly bring digital cash into your store. Curious how Cashu can transform your business and give your customers true payment privacy? Check out the full blog post here:

Unlock the future of Bitcoin node performance with our newest blog, Schnorr and Steady Wins the Race: The Case for Batch Validation. Oghenovo dives deep into how BIP340 Schnorr signatures and batch verification are transforming the efficiency of Bitcoin Core, explaining the math behind it, the use of multi-scalar multiplication, and the real benchmark data that demonstrates faster block verification times. As Taproot continues to gain traction and new technologies like Silent Payments, MuSig2, and FROST drive even greater Schnorr adoption, these optimisation techniques become essential to keep Bitcoin scalable, private, and secure. If you want to understand the mechanics of batch validation or see the real-world impact on block validation speed, this article covers that and sets the stage for the next era of Bitcoin scalability.
