Ha, yes, that's confusing. The Bao project was originally two things: 1) a custom tree hash mode, and 2) an encoding format and verified streaming implementation based on that tree hash. The first half evolved into BLAKE3. Now the Bao project itself is just the second half.
The README lists 4 designers, including yourself. However the Bao project doesn't list anybody, so presumably you are the only designer. What exactly were the contributions of the other 3 people to warrant being listed?
At what point did the Bao project become "BLAKE3" and why?
