Bitcoin started as open source without any initial funds and it is amazing that it survived and thrived for so many years, but new developers and projects are always good to have.
Example projects they will be supporting:
- Significant code and/or Bitcoin Improvement Proposal (BIP) review
- Contributor tooling (e.g., bitcoinacks.com, which is open source)
- Bitcoin Core libraries and tools (e.g., libsecp256k1)
- Improvement to testing (e.g., fuzz testing, functional tests)
If you are Bitcoin Core developer you can apply or suggest someone HERE
Good move from Coinbase and I expect other crypto related companies to follow their example, and we want to see more interesting development around Bitcoin.
