Verification glossary defines terms such as signed proof, spent proof, KYA, HEAA, and Merkle audit as used across AffixIO documentation and compliance guides.
Signed proof
Allow or deny plus cryptographic evidence the outcome is genuine.
Stateless
Each request answered and discarded. No standing profile at verifier.
Zero-knowledge proof (ZKP)
Proves a statement true without revealing underlying data.
Post-quantum cryptography (PQC)
Algorithms designed to resist quantum attacks. AffixIO uses ML-DSA-65.
ML-DSA / FIPS 204
NIST post-quantum signature standard used on attestation paths.
Merkle audit
Append-only hash tree of verify decision digests.
Spent proof
Credential already consumed. Re-presentation returns DENY.
Know Your Agent (KYA)
Verify agent scope before autonomous actions execute.
Highly effective age assurance (HEAA)
Ofcom standard under the Online Safety Act.
Proof-not-log
Cryptographic audit instead of mutable application logs.
Model Context Protocol (MCP)
Protocol connecting AI clients to tools. AffixIO hosts Proof by AffixIO.
Agentic payments
Payments initiated or delegated by AI agents.
Harvest now, decrypt later
Capture encrypted data today to decrypt after Q-Day.
Selective disclosure
Reveal minimum attribute needed, e.g. over 18 only.
