+1 for blake2. Good adoption in other projects, addresses the need for
speed.
Cheers,

On the contrary.
-tree implementation and SHA3 is completely dominating
performance, in a bad way. I'd rather not being already limited by SHA3 in how
fast we can add outputs to the sum tree.

My apologies for bike shedding, but have you considered SHAKE128? It uses the
same Keccak function but with saner (faster) parameters and you use the
extensible output for simpler generation of several blinding factors, forged
elements etc.

Hi all,
I originally picked SHA3 (Keccak) for all hashing in grin [1]. The advantages
of SHA3 over SHA256 are numerous (more modern design, less known weaknesses,
designed independently from NSA, well studied and long review process, etc.)
which motivated my original decision. However it turns o
