Questions
Frequently asked questions
How MintID keeps identity off the chain while letting holders prove claims in zero knowledge — from issuers and assurance grades to key recovery, self-revocation and agent KYC.
What is MintID?
MintID is a sovereign, permissionless proof-of-stake Layer-1 for privacy-preserving, KYC-backed identity credentials.
Does the chain store my identity documents?
No. No raw KYC, PII, names, addresses, biometrics, credential payloads, serial numbers or presentation logs ever touch the chain. It carries only issuer/verifier records, status-root commitments, staking, governance and audit commitments.
Who can issue credentials?
Only KYC organisations approved by the compliance council — the "accepted issuers".
What is a zero-knowledge presentation?
The holder proves a claim (for example "grade ≥ A3", "over 18", or "credential active") against on-chain trust roots without revealing the underlying attributes or which credential was used.
What are assurance grades A1–A4?
A private four-level assurance grade; only a commitment is public. A verifier can receive a threshold proof such as "grade ≥ A3" without learning the exact grade unless the holder chooses to reveal it.
What if I lose my keys?
Recovery is only by fresh KYC re-verification, which issues a new, publicly unlinkable credential. No one custodies your keys for you.
Can I revoke my own credential?
Yes. Holder self-revocation works without issuer cooperation and reveals neither your identity nor a normal credential identifier.
How long is a presentation valid?
Ten seconds — bound to a unique challenge, the exact audience and origin, the requested policy, the current issuer status root and a finalized chain height.
What is agent KYC?
A human does KYC once, then mints many privacy-preserving agent credentials. Each agent proves it is backed by a KYC-verified, liable human principal at assurance ≥ G within delegated scope S — without revealing which human, and without sibling agents being linkable.
Is there a token, and is it live?
There is a native token with a hard-capped, declining monetary policy; rewards are on-chain consensus rewards. MintID is research-stage — no mainnet before independent application, cryptography, infrastructure and economic audits. Nothing here is financial advice or an offer of securities.
Do testnet tokens have any value?
No. Testnet tokens are free, unlimited, and worthless — deliberately. They exist so developers and validators can exercise the network, will never convert into any future mainnet token, and may be deleted at any time through test-network resets.
