“Identity providers verify users, attest on-chain, and addresses get identity tags. The network knows enough without knowing too much.”
Verify. Attest. Transact.
Decentralized identity attestation gives every address a verifiable reputation without a central database.
Verify
Identity providers verify the user's credentials off-chain.
Attest
A signed, privacy-preserving attestation is recorded on-chain.
Transact
Smart contracts check the attestation before allowing regulated actions.
Identity primitives for every use case.
Four capabilities that make decentralized identity practical, private, and regulator-friendly.
ZK-proof identity
Verify identity claims without revealing the underlying personal data. Privacy and compliance together.
Tiered identity levels
Basic, enhanced, and institutional tiers with matching transaction limits and risk treatments.
Revocable attestations
Identity providers can revoke or update attestations when status changes, with on-chain revocation proofs.
Multi-provider support
Competing identity providers can attest to the same user, reducing single-provider risk and censorship.
The right level for every user.
Not every user needs the same verification depth. BLINK supports tiered identity levels that match risk, jurisdiction, and transaction size.
Regulators can query whether an address holds a valid attestation, its tier, and its jurisdiction — all without touching personal data. Zero-knowledge proofs keep privacy intact while proving compliance.
