OSS Where Grads End Up
✓ rawBit is for you if
→ You're comfortable in at least one programming language → You want to understand Bitcoin at the protocol level - not just use it → You can commit ~5 hours a week for 10 weeks → You want a clear path into Bitcoin open source contribution
✕ It's not for you if
→ You've never written code - start with Bitcoin Basics instead → You're looking for trading or price talk - wrong school → You can't make the weekly sessions work (they are recorded, but homework is paced) → You want a certificate more than a merged PR
/Curriculum_

Ten weeks. Raw bytes to first PR.

Every week pairs a live session with hands-on homework against a real node. Merged homework earns sats. The final two weeks point everything at your first open source contribution.

/How_It_Works_

Built like a contribution pipeline.

01 Weekly live session Protocol deep-dives on Discord, every week, recorded. Bring questions - sessions are working sessions, not lectures.
02 Homework earns sats ⚡ Each week ships a hands-on assignment against a real node. Complete it, get it reviewed, get paid in sats.
03 Mentor code review Working Bitcoin developers review your code the way maintainers will - so your first real PR isn't your first review.
04 Graduate into OSS Weeks 9–10 point at your first contribution: finding an issue, writing the PR, handling review. Graduation = shipped.
/After_rawBit_

Graduation is a starting line.
