From Grok, when asking the right questions. Lattice-based cryptography (as used by Midnight on testnet) draws on hard lattice problems to deliver post-quantum security plus algebraic structure that supports efficient ZK folding, homomorphic encryption, and more sophisticated private computation. Ethereum’s hash-based approach, which Justin Drake and the protocol have heavily invested in, instead rests on the simpler, longer-studied assumption of hash-function collision resistance; this is sufficient for the signatures and proofs Ethereum’s Layer 1 currently needs, but lacks the extra structure that privacy-oriented or folding-heavy systems can exploit.
