Zcash cofounder Eli Ben Sasson has publicly backed Ethereum cofounder Vitalik Buterin's approach to making Ethereum quantum-ready. The ongoing debate on X, also joined by Delphi Labs GC Gabriel Shapiro, centers on lattice versus hash-based cryptography in blockchain design. Buterin's strategy involves fully replacing BLS signatures with hash-based signatures (a variant of Winternitz) and using STARKs for aggregation, while potentially utilizing lattice cryptography for accounts and wallets through a precompile if it proves AI-secure. Ben Sasson agreed, stating, "this is the right way for Ethereum."
