Sign Protocol and the Gap Between Intent and the Final Signature
What makes Sign Protocol interesting to me is that it does not treat a signature like the whole story. The signature is only the final proof layer. Before that, there is intent, schema design, signer authority, and the rules that decide what the claim is actually supposed to mean. Sign’s own docs explain attestations as digitally signed structured data that must follow a registered schema, and its FAQ makes clear that verification also involves checking the signer, signing domain, authority, status, and supporting evidence. That is a much stronger model than acting like one final signature solves everything.
To me, that is where the real value sits. Sign Protocol helps close the gap between what someone meant to approve and what a system can later verify, query, and trust at scale.
