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. Here’s how it works: 🔸 Month 1: A fully guided, hands‑on learning experience featuring coding exercises, mentorship, and technical discussions led by Bitcoin open‑source contributors. 🔸 Months 2 & 3: Top performers continue with advanced mentorship and project work through Chaincode Labs, while other participants engage in partner‑supported pathways to keep learning and building. This program has already helped developers across Africa launch into meaningful open‑source careers. Several participants from the 2025 cohort are now Btrust-funded grantees contributing full‑time to Bitcoin and Lightning projects. If you’re a developer ready to learn, build, and contribute to Bitcoin open‑source software, this is your opportunity. 🗓️ Applications are ongoing until December 31st, 2025. 🗓️ Program starts the week of January 12th, 2026. Learn more about the partnership and program in our latest blog post:

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.

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.
