The "too much crypto" paper linked in the specs recommends to lower Chacha20 down to 8 rounds.
Blake3 wouldn't compete with Chacha20, it would compete with Chacha8.
- oconnor663 7y agoNote that a "round" in BLAKE/2/3 is equivalent to a "double-round" in ChaCha.
- loeg 7y agoAh, ok. So 7-round Blake3 is perhaps closest to 14-round Chacha.
