If you’ve ever wanted to work as a developer in #Bitcoin, this is your BEST chance to get started!
I am a product of these same open source teaching programs and seminars by @ChaincodeLabs (back in 2018) — it changed my career path in ways I hadn’t thought possible.
I cannot recommend the BOSS Challenge enough!
JUST SIGN UP ALREADY 🚀🫡🤞

As Charles Dickens once said, “This is a three-month educational program that helps people get into bitcoin development full-time. It starts with education, introduces challenges, and then, if you excel, @ChaincodeLabs will help you find a job in bitcoin. It kicks ass, man.”

“The ₿OSS challenge really helped me think deeply about Bitcoin and learn more about it and open‑source development.” @Camilla_rhi, 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 Bitcoin’s Lightning ecosystem.
Now, as a @btrustteam 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 @ChaincodeLabs. 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. If you’re a developer passionate about learning, contributing, and building for Bitcoin, this is your chance.
🗓️ Applications close December 31, 2025
🗓️ Program starts the week of January 12, 2026

A lot of awesome new contributors popped up in the last year or two. The one thing many of them have in common? Going through the @ChaincodeLabs ₿OSS program. Probably the most effective way to get started in Bitcoin Open Source development right now.

We’re excited to partner with @ChaincodeLabs once again for the 2026 ₿OSS (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 @btrustteam-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 31, 2025.
🗓️ Program starts the week of January 12, 2026.
Learn more about the partnership and program in our latest blog post: blog.btrust.tech/btrust-buil…

In 2016, I hosted the first residency of its kind for bitcoin devs and @chaincodelabs has continued the tradition to bring more devs into bitcoin FOSS.
We have a lot of work yet to do and we could use all the help we can get.
