  2. …that go into how fast a hash function is, but the case we're showing in the big red chart at https://github.com/BLAKE3-team/BLAKE3 is almost entirely driven by SIMD. It's a huge deal.

  14. Huh, I didn't know that. https://github.com/BLAKE3-team/BLAKE3/blob/b404c851c284ed01f... I peeked at the reference impl (380 lines of safe Rust) and found this. It has a 1,728-byte array for tree state, which is enough for 2 ^ 64 bytes. So…
