I just signed a freelance contract on EthSign last week. The contract is signed on-chain, immutable, and indisputable.
But when I wanted to use that track record to apply for a DAO grant, there was no way to port that information over 😤
This is indeed the gap between contract and behavior that Sign is trying to fill.
The contract on EthSign creates an attestation about commitment. On-chain behavior creates an attestation about execution. Reputation from various protocols creates an attestation about track record. Sign's schema registry defines a common standard to link all of these things together.
SpIDs create a unique identifier cross-chain for every entity in that graph. Schema hooks automatically update trust scores when behavior changes.
When those three layers work together, contract, behavior, and reputation no longer live in three separate silos. They become a composable trust graph that any protocol can query and act upon.
