Many projects talk about 'verifiability', and the position they stay at is quite similar: first produce the proof, then assume the world will use it. But reality is not like that. If nobody looks at the proof, nobody checks it, and nobody can read it following the same structure, it can easily become just a screenshot lying on the chain. SignScan made me notice this layer. The official definition describes it as an indexing and aggregation service for @SignOfficial , providing a unified REST / GraphQL API to query, aggregate, and read these schemas, attestations, and related data.

This position may not look eye-catching, but it is actually crucial.

EthSign is responsible for leaving a record of the signing and execution process, while Protocol is responsible for writing the declaration into a verifiable structure. However, if there isn't a layer that can continuously read, match, and verify these things, the entire system will still be stuck at 'theoretically verifiable'. The value of SignScan lies precisely in pushing 'leaving evidence' one step further, turning it into 'evidence can later be systematically seen'.

Returning to $SIGN , this line is no longer just a conceptual packaging.

If Sign is to take on a whole network of proofs that are continuously generated, queried, and reused, then SIGN should correspond not just to identity or signature type labels, but be closer to the entry value used long-term by the entire system. The less lively this layer is, the more likely it is to determine whether the project can stand firm. #Sign地缘政治基建
