Cohort 5 of the Ethereum Protocol Fellowship wrapped up late last year.

5 months, 30 fellows, a ton of meaningful contributions to Ethereum core.

Some highlights 👇

Projects shipped specs, tests, client code, docs, metrics… not just learning — real impact.

EPF6 coming soon. If protocol dev is on your radar:
→ Start now at epf.wiki
→ Contribute in public
→ Be ready to apply

Ethereum is an open door. You can just walk through.
But if you just need a starting point, this is one.
