Why it is “global” and reusableBecause Sign uses standardized schemas and open standards (W3C Verifiable Credentials, DIDs, OIDC‑style flows), a credential issued by one agency (e.g., a national ID authority) can be re‑used by many others (tax, welfare, banking, cross‑border payments) without leaking raw personal data, only the proofs that match the policy. This turns SIGN into a global “trust layer”: instead of every app or country building its own bespoke KYC stack, they all plug into the same omni‑chain attestation network, paying and staking $SIGN to secure and query credentials at scale.

What Sign Protocol does

1. Standardizes how facts are expressed (schemas)

2. Cryptographically binds data to issuers and subjects

3. Enables selective disclosure and privacy

4. Supports public, private, and hybrid attestations

5. Provides immutable audit references

Sign Protocol enables privacy‑preserving verification by letting users prove specific facts (identity, age, eligibility, KYC status, etc.) without exposing the full underlying data to every verifier. Instead of sharing raw personal information, applications only receive a cryptographically verifiable claim that can be checked against a trusted “evidence layer” (Sign Protocol’s attestation layer).
