“In 2024, a scientist claimed lattice based crypto could be broken by quantum computers, though it turned out to have a bug in the logic. Now he’s back, saying it’s fixed. No panic: cryptographers must carefully re-examine the claim.” Moments like this highlight why Sui Research’s recent backwards-compatible quantum-safe transition is such a vital step for secure post-quantum migration for most blockchains. We clearly mentioned our approach should be generalized even against the new digital signature schemes based on lattices. It doesn’t really matter if the new attack will hold, but application of our method is exactly there to provide a backup if bad things ever happen.
