    What you get

    Selective disclosure
    Reveal only the attributes you pick. Hidden fields stay hashed under a salted Merkle root signed by the issuer.
    Zero-knowledge predicates
    Prove "age ≥ 18", "nationality ∈ EU set", or "KYC tier ≥ 2" without revealing the underlying value. Groth16 over BLS12-381.
    WebAuthn passkeys
    ECDSA P-256 signing inside the secure enclave. Private keys never touch JavaScript or your servers.
    Live revocation registry
    Revoke, suspend, reactivate. Verifiers receive push events over WebSocket — invalidate cached results instantly.
    Plug-in IdP issuance
    DigiD, BankID, OIDC, SAML, and Didit KYC out of the box. Bring your own provider via the form, OIDC, or webhook flows.
    On-chain trust anchor
    Issuer keys, revocations, and identity commitments published on Midnight. No central directory, no key escrow.
