Just read the BLAKE3 paper. I'm really happy to finally see a standardized tree-based hash function that is fast on all architectures. Existing hash functions either didn't come with a tree mode (everyone had to invent their own incompatible tree algorithm) or had too many different (and domain-separated) modes - making cross-referencing hashes across multiple protocols impossible.

BLAKE3 should allow one to publish a single file hash that could be used both for identification and incremental verification on across multiple (P2P) file sharing networks. I'm hoping it will get adopted.
