“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:

“The ₿OSS challenge really helped me think deeply about Bitcoin and learn more about it and open‑source development.” Rita, 2025 ₿OSS alumna. Meet Rita, a Lagos🇳🇬‑based software developer and one of the 2025 ₿OSS alumni. Before joining the program, Rita already had over three years of experience building and improving fintech and logistics solutions. But her time in the ₿OSS program became a turning point. Through the program, she deepened her understanding of Bitcoin technologies and the Lightning Network, contributing to major open‑source projects like LDK Node, Warnet, and CircuitBreaker; critical components that underpin the scalability and resilience of @Btrust grantee, Rita is continuing her work full‑time on LDK Node and Warnet, focusing on improving transaction lifecycle management, payment tracking, and developer tools to make Bitcoin infrastructure even more reliable and user‑friendly. Rita’s journey is a great example of what’s possible through the BOSS Challenge, created by Chaincode Labs. This is a structured, hands‑on program designed to help developers start building open‑source Bitcoin projects and grow into funded contributors. Ready to build your own Bitcoin story? Applications are ongoing for the 2026 BOSS 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 recently had the pleasure of participating in the 2025 #BtrustGathering in Mauritius🇲🇺. Our faculty, several alumni, now @Btrust grantees, and top students from the 2025 pathways were all represented. Our program lead, Stephanie Titcombe, walked attendees through our 2025 program report, highlighting achievements like the program redesign (

) and the strengthened support plan for builders in the BOSS program. We also spent time collaborating with builders and Global South programs to explore ideas that will help us refine and elevate our work going into 2026. It was great finally meeting people we’ve only worked with online and reconnecting with familiar faces. Looking forward to the work ahead. 💪

We’re excited to partner with Chaincode Labs once again for the 2026 BOSS (Bitcoin Open‑Source Software) Challenge. 🚀 The ₿OSS Challenge is a structured, hands‑on program designed to help developers take their first steps into Bitcoin open‑source development.

Last Saturday, BitDevs Kano 🇳🇬 held their first Bitcoin and Lightning-powered hackathon exploring open-source solutions for EdTech challenges in Nigeria. Over 50 participants spent the day forming teams, building prototypes, and exchanging ideas on how blockchain and Lightning technology can improve access and transparency in education. Mentors guided the process, and quick lightning talks sparked fresh thinking between coding sessions. The event highlighted Bitcoin’s potential in tackling real-world challenges while strengthening Kano’s growing developer community.

Behind every successful Btrust Builders cohort is a faculty team whose dedication carries the program forward. 🧡 This year, many of them, alumni themselves, returned to mentor, teach and walk alongside participants, turning their own experiences into guidance for the next wave of open‑source Bitcoin and Lightning developers. We’re proud to celebrate this collective of builders and mentors who made this year’s journey so meaningful. Their stories are inspiring, and their contributions remind us that the heart of Btrust Builders lies in its people. 👉 Read more about them on our blog:

We’re excited to share Bitcoin Core Principles by @La Librería de Satoshi 🚀 This course goes beyond how Bitcoin works to explain why it was designed with decentralization, absolute scarcity, and immutability, and why the base layer changes slowly on purpose. During the course you’ll cover: • The philosophy of decentralization and the trade-offs that keep Bitcoin neutral. • Why scarcity matters, how the timechain protects history, and why finality is social as much as technical. • Fungibility, privacy, and scalability across layers. • How change happens: BIPs, social consensus, activation paths, real case studies. • The developer ethos: humility, ossification, and building for the long term. Participants will engage in socratic, discussion-led sessions rather than passive lectures. They’ll also work through curated readings and hands-on workshops to cement their understanding. There will be experienced facilitators to guide participants through the sessions. Application deadline is October 10th, 2025 Classes start on October 13th and will be happening every Monday & Wednesday. The course is offered in English, Spanish and Portuguese. 🔗 Learn more, apply and share with a friend:
