@TabConf is participating in the 2026 â‚¿OSS (Bitcoin Open Source Software) Challenge, a Chaincode Labs program built for developers who want to begin contributing to Bitcoin open source in a real, structured way.
Start Your â‚¿OSS Journey with TabConf!
It’s fully online, free to join, and designed for all experience levels. What matters most is that you’re serious about doing the work.
Here’s the shape of it. Month 1 is a guided, hands on sprint through programming exercises and learning material, with active contributors in the mix and lots of async support. Plan for at least 10 hours a week.
After Month 1, you can keep going into Months 2 and 3, where the journey shifts into partner programming, seminars, and deeper contribution paths, with some advanced participants getting access to additional opportunities. Learn more about the program: bosschallenge.xyz
Applications are open now and close on December 31, 2025. The cohort kicks off the week of January 12th.
If you’ve been waiting for a clear onramp into Bitcoin open source, this is it!
One important note: the application form includes fields for a phone number and resume, but you should not submit either of those.

See you in the challenge,
