From Hours of Proof Time to Millisecond Verification
When zero-knowledge rollups were first conceptualized, generating a cryptographic proof for a block containing hundreds of complex smart contract transactions required supercomputers running for dozens of minutes. Proving circuits were bottlenecked by large number-theoretic transforms (NTTs) and multi-scalar multiplications (MSMs).
The convergence of custom PCIe accelerator cards and recursive folding schemes (such as Nova and HyperNova) has transformed this performance envelope. Rather than proving an entire batch monolithically, proofs are folded recursively into compact succinct proofs verified on-chain for mere fractions of a cent.
