'Right Way for Ethereum?' Zcash Cofounder Backs Vitalik's Quantum-Ready Approach

There is an ongoing debate on X about lattice versus hash-based cryptography in blockchain design, with Zcash cofounder Eli Ben Sasson, Ethereum cofounder Vitalik Buterin , and Delphi Labs GC Gabriel Shapiro joining the discussion. The conversation began with a16z crypto making the case for embracing lattices in a recent X post. In a write-up, a16z crypto explained its rationale; it claims Ethereum's planned hash-only signature aggregation design relies on SNARK recursion, with the coordination overhead, bug surface, and unestablished security that come with this approach. Engaging with a16z crypto's post, Zcash cofounder Eli Ben Sasson strongly disagreed, noting that lattices have a juicy mathematical structure that is ripe for AI to attack.
