WISCH: Efficient Data Signing via Correlated Signatures
We introduce WISCH, a protocol that generates correlated sets of signatures across different signing schemes or messages. By exploiting this correlation, WISCH can serve as a drop-in replacement for existing schemes, reducing on-chain signing costs by at least 5× compared to Winternitz and 10× compared to Lamport and GC Wire labels.
