Wasn't too long ago Vitalik hardly considered quantum computing a threat. Now he's questioning if even post quantum cryptography could be at risk. Though he notes we will need some form of post quantum cryptography: "However, signatures and encryption serve different purposes. Buterin argued that public-key encryption presents a harder challenge because it needs mathematical structure beyond hashes alone." My take is you need a solution to get off ecdsa / rsa yesterday because these were already at risk with "human" math. And you need crypto agility in case AI math solves post quantum cryptography.   submitted by   /u/Original-Assistant-8 [link]   [comments]
