as a BLAKE3 codesigner, happy to be one of judges in HashSmash! 💥
NIST needs to launch a post-AI cryptography competition
proof of 0 = 1 in Lean, exploiting a hash collision (weak 32-bit hash Expr.hash/mixhash)
no system is fully secure, secure hardware has limits, software has bugs, even blockchains;
attackers target blockchains (direct monetary return, anonymity, open platforms etc.), and imo neither the best defenders nor the best whitehats are in the blockchain space

so many landmines and footguns when deploying complex crypto protocols; easy to say "they shouldve known better"
