Category: human-origin attestation protocol / digital provenance infrastructure / credential-and-ledger content-authenticity system
Summary: Human Integrity Protocol is worth cataloging not as just another provenance badge, creator tool, or generic AI detection pitch, but as a protocolized attestation stack for human-made content. The public materials split the system into a Bitcoin-rooted genesis layer, HUMAN-PROOF credentials, pathway-governed issuance, Trust Index mechanics, point-of-use liveness, and proof-bundle specifications. That makes HIP a useful comparison point for digital provenance and proof-of-personhood systems because the real control surface is not only did a human make this, but who can issue credentials, how pathway health is monitored, how credential weight decays or survives review, and how attestations become portable verification artifacts.
What it does:
Lets creators produce cryptographic attestations that content is CHO (Complete Human Origin), HOA (Human Origin Assisted), or HDC (Human-Directed Collaborative)
Anchors protocol genesis and charter lineage to a Bitcoin inscription while publishing supporting payloads and documents through IPFS and Arweave
Uses HUMAN-PROOF credentials with ledger-visible issuance history, lifecycle state, compromise records, and key-rotation history
Introduces an internal Trust Index composed of issuance weight plus behavioral score, along with point-of-use liveness checks and rate-limiting rules around attestations and vouching
Defines issuance pathways with tiering, pathway-health monitoring, review/suspension/declassification states, and contingency-pathway migration logic
Positions products like HIPKit as optional implementations built on the protocol rather than as the protocol itself
Key claims:
The main repository describes HIP as a cryptographic attestation system that lets human creators prove — verifiably, permanently, and without any institution's permission — that their work is human-made
The README says the protocol does not store the underlying content and does not directly handle identity data; pathway providers perform verification and the protocol receives only limited derived signals such as a one-way dedup hash, tier label, and pathway identifier
The genesis materials matter analytically because every later attestation is framed as tracing back to a Bitcoin-inscribed root, with public verification steps for the payload, charter hash, firewall hash, and guardian signature
HP-SPEC-v1 makes clear that the Trust Index is not a public human-ranking score but an internal credential-confidence instrument that governs protocol treatment, behavioral history, and classification access gating
PATHWAY-SPEC-v1 exposes a separate governance layer around pathway tiering, PHI monitoring, review/suspension/declassification, and contingency paths, which means issuer-pathway policy is a first-class control plane rather than a hidden ops detail
Some of the ecosystem is still early or not fully published. The repo explicitly notes companion specs that are finalized but publication-pending, and the current PATHWAY spec is still a stub rather than a full canonical spec release
Whitepaper: No single standalone HIP whitepaper PDF was confirmed in this pass. The strongest primary materials were the official site, the main protocol repository, and the published HUMAN-PROOF and PATHWAY specifications; see ../whitepapers/human-integrity-protocol-primary-sources-2026-05-12.md.
