Validity rollup (ZK rollup)
L2 that posts validity proofs to L1—advanced proofs are not the same as quantum-safe user wallets.
Definition
Validity/ZK rollups use cryptographic proofs to assert correct execution. Some proof systems have different quantum assumptions than ECDSA.
Even so, user account signatures, bridges, and admin keys may remain classical. Always separate proving systems from authorization crypto.
