Ethereum Update on Signature Schemes
Ethereum co-founder Vitalik Buterin discussed the network's ability to support any signature scheme without adding another precompile. He addressed concerns about public-key encryption and the potential for a 'bigkey regime' where public-key systems need objects as large as 2^30 to resist an attack of complexity 2^120. Buterin recommended waiting three to five years before trusting lattice-based cryptography, which he believes could be vulnerable to AI-assisted attacks. He proposed a new method where users create their own signature locally and submit it through a precompile, avoiding the need for additional precompiles on the Ethereum network.
