Digital identity ยท PQC attestation
Identity checks that answer the gate, not the vault
AffixIO is verification infrastructure for digital identity workflows. Prove eligibility, age, or credential scope with a signed allow or deny. Noir zero-knowledge circuits and ML-DSA-65 (FIPS 204) attestation. Built for post-quantum computing (PQC) and UK digital verification programmes that need evidence without a standing identity store at the boundary.
What /id covers
Identity providers establish who someone is. AffixIO evaluates a policy question at the moment of action and returns cryptographic proof. Use it beside IAM, wallets, or KYC vendors when the gate only needs yes or no.
Post-quantum computing (PQC)
ML-DSA-65 signatures aligned with NIST FIPS 204 so long-lived identity decisions resist harvest-now-decrypt-later risk.
UK trust context
Maps cleanly to digital verification services programmes that demand auditable outcomes and data minimisation at the verifier.
Agent and human gates
Same allow or deny pattern for people, tickets, and non-human identity (NHI) agent permissions.
How the check runs
Prove on your host with @affix-io/sdk, or call the REST API. AffixIO signs the outcome, optional Merkle audit records the decision digest, and input fields are discarded at the verifier by default.
1. Prepare witness
Hash or commit attributes on integrator infrastructure. Credential material stays where you already trust it.
2. Prove
Generate a circuit proof for the eligibility predicate. Sandbox and SDK docs cover the live path.
3. Verify
Boundary receives signed allow or deny. Scanners and APIs check attestation without re-opening personal data.

Questions
Short answers for buyers and engineers mapping this page to AffixIO verification infrastructure.
Is AffixIO an identity provider?
No. AffixIO returns signed allow or deny for a policy question. Identity providers manage accounts and sessions. The layers are complementary.
Does AffixIO store identity documents?
Not at the verifier by default. Requests are evaluated in memory, signed, and discarded. Optional Merkle audit stores proof metadata, not document images.
How does post-quantum computing (PQC) fit?
Attestation uses ML-DSA-65 aligned with NIST FIPS 204 so proofs remain verifiable as classical public-key algorithms age out.
Where do developers start?
Open the sandbox, read /sdk/docs, or install @affix-io/sdk from npm. OpenAPI is published at /openapi.json.
