Most credentials we rely on work because someone behind them can be held responsible. A university. A bank. A government office. Remove that institution and the question of who answers for a false claim becomes genuinely unclear.
Decentralized attestation systems face this directly. When anyone can issue a signed statement on-chain, the signature proves the act happened. It does not prove the claim is accurate or that the issuer should be trusted.
This is the space $SIGN operates in. Sign Protocol records attestations without embedding judgment into the base layer. The schema, the signer, the resolver each carries a portion of the accountability that used to sit with one institution.
Whether that distribution holds up under pressure is something the ecosystem is still figuring out.
The question is not whether the system is trustless. It is whether distributed trust is enough.
