Bao, a general purpose cryptographic tree hash, and perhaps the fastest hash function in the world

This is a talk I gave at the Rust NYC meetup on November 27, 2018. UPDATE in 2020: The Bao project at the time of this talk was two things, a custom tree hashing mode based on BLAKE2, and an implementation of verified streaming based on that tree mode. In the year after I gave this talk, the tree mode evolved into BLAKE3, which we released on January 9, 2020. The current version of Bao no longer defines a tree mode of its own, but instead implements verified streaming on top of BLAKE3. That said, the Bao hash described in this talk is very similar to BLAKE3 + Bao today, and this talk is still useful for understanding how it all works.
