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.
