BLAKE2 was part of the SHA3 competition and it was in finalists. The SHA3 competition is interesting because each algorithm is deeply tested and analyzed by many teams all around the world. Obvious vulnerabilities are quickly found. The advantage of putting SHA3 and BLAKE2 in the stdlib is that they have a different design. I don't expect that two designs have the same vulnerabilities, but I'm not ax expert :-) SHA3 (Keccak) is based on a new sponge construction: https://en.m.wikipedia.org/wiki/SHA-3 BLAKE is based on ChaCha: https://en.m.wikipedia.org/wiki/BLAKE_(hash_function) https://en.m.wikipedia.org/wiki/Salsa20#ChaCha_variant Victor
