Blockchains solved execution without trust. You no longer need to believe a counterparty will deliver; the code enforces it.
Yet they never resolved a deeper uncertainty: are the entities behind those addresses who they say they are?
Trustless does not mean verifiable. The chain confirms a transaction occurred.
It cannot confirm the wallet belongs to a legitimate business, a credential holder, or a KYC-compliant user.
Sign Protocol builds the missing layer.
It creates structured attestations cryptographic signatures on registered data schemas that smart contracts can directly read and verify.
Not promises, but machine readable proofs.
What truly distinguishes it is omni-chain portability.
An attestation issued on Ethereum can be verified on Solana or TON without intermediaries or fragmentation.
TokenTable has already used it to manage over 130 million dollars in on-chain distributions. That’s measured adoption.
The protocol’s honesty lies in its limit: it standardizes the form, not the attester’s credibility.
Value still depends on the source. This raises the real question.
If Web3 wants institutions, states, and enterprises, does it need a verifiable trust layer sitting above execution or is that simply borrowing back from Web2?
