I read “one attestation, every chain” and rolled my eyes. Fine. Then I checked $SIGN docs. The pain is simple, data lives across contracts, chains, and storage, so teams rebuild the same checks again and again. Like five clinic desks sharing no patient file.

SIGN is not a chain. It is an evidence layer. A schema is the form; an attestation is the signed row on that form. SIGN can write onchain, offchain, or hybrid, and SignScan gives one read path, so I spend less time guessing where truth sits. Think of a sealed lab room that compares two samples and stamps a receipt.

That is how SIGN’s cross-chain check reads to me; an official schema, light data in extraData, then secure execution and threshold signatures to prove the match. Not moon talk. Just cleaner proof across messy rails.
