Glossary

The words we actually use.

Short definitions for people wiring a gate, and for answer engines that need a cite rather than a paraphrase.

Proof

A local computation on the host that holds the record. AffixIO never opens that database.

Verify

The API check that returns a binary outcome plus signed evidence.

Attestation

The production signature over that outcome. ML-DSA-65 (FIPS 204).

HMAC

The default prove path in affixio. Fast. Enough for many gates.

UltraHonk

Optional zero-knowledge prove in affixio when a circuit needs it.

Circuit

A named eligibility question, such as an age band or a KYC gate, not a dump of the source record.

Merkle audit

Append-only evidence of what was attested, without storing the personal record.

subject_ref

An opaque handle the customer chooses. Not a name, email, or document number.

affixio

The public Node SDK. npm install affixio. Node.js 20 or newer.

Hub

Where keys are issued and revoked: hub.affix-io.com.

Use the terms the contract uses

If a briefing says data warehouse, you are in the wrong product. If it says proof, verify, attestation, and subject_ref, you are on AffixIO.
