Ethereum

today I was looking again into BLAKE3 and I'm getting more and more convinced that we should add it to the EVM. Thoughts? Like, it's way more efficient than SHA-256 and - maybe this is just my paranoia - SHA-256 was designed by the NSA... interesting fact, the Beacon deposit contract uses SHA-256 12 times.

BLAKE3 is great, I hope it gets more adoption. 

We passed on using in FC in 2021 because of lack of EVM support and mature libraries.

It doesn't seem to be especially zk friendly right? Looks like it's a descendant in the chacha20 family, and DJB seems to be pretty reliable. Interesting that Zooko was involved in BLAKE2 and 3.

Also note that SHA3 has an NSA padding tweak, but Ethereum uses raw Keccack without the tweak, so zero NSA influence.

It should also be pointed out that the NSA tweak that differentiates SHA0 from SHA1 actually ended up being a significant improvement that no one figured out until way later. Every once in a while the NSA actually does something helpful 😄
