✓ 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.
Full curriculum on GitHub →/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.
