About
Sign Protocol is the cryptographic evidence and attestation layer in the S.I.G.N. infrastructure stack. It lets governments, institutions, and developers define structured schemas, issue verifiable attestations, anchor evidence across chains and systems, and query or audit records. The protocol supports public, private, hybrid, and selective-disclosure attestations rather than operating as an end-user application.
