Thinking about a career in Bitcoin open-source development?

The BOSS Challenge by Chaincode Labs is designed to help developers take their first steps into the Bitcoin open-source ecosystem.

Alumni from previous cohorts have gone on to build funded careers in open-source development.

Applications close tomorrow, and you have until January 12 to complete the preliminary challenge (Saving Satoshi).
