  5. Thanks! I've added a note about this here: https://github.com/oconnor663/bao/issues/41#issuecomment-119... . Does that sound like an accurate summary to you?

  6. …hash of a file while you stream it rather learning whether it was valid at the end of the stream. https://github.com/oconnor663/bao . That's useful if you know the hash of a file but you don't necessarily trust the service that's storing…

  7. …. An early BLAKE3 prototype actually didn't include the chunk counter ( https://github.com/oconnor663/bao/blob/master/docs/spec_0.9.... ), so I'm definitely sympathetic to the use cases that wish it wasn't there. However, after pu

  11. If you squint at it, there's also a Python implementation here: https://github.com/oconnor663/bao/blob/master/tests/bao.py . But it's far too slow to use it for anything besides testing.
