Public Registry
Public Registry of Certified AI Artifacts
Definition
AI artifact registry:
The artifact registry is the public, machine-readable index of AI artifact certificates and certified artifacts on CertifiedData. It stores certificate-linked records for synthetic datasets, AI models, outputs, and related artifacts together with verification links and SHA-256 fingerprints.

Related concepts
A machine-readable index of synthetic datasets, AI models, and registered artifacts with cryptographic certification records. Each certified entry exposes a SHA-256 fingerprint, an Ed25519-signed certificate, and an independent verification link.
About this registry
The CertifiedData Registry is a public index of cryptographically certified synthetic datasets, AI models, and AI system artifacts. Each entry includes a SHA-256 artifact fingerprint, an Ed25519 digital signature, and an independent verification link. Learn about synthetic data certification or AI artifact certification — or generate and certify your own dataset.
What is this registry?
This is a public index of AI artifacts that have been registered with CertifiedData and optionally certified. Each entry records a SHA-256 artifact fingerprint at the time of registration. When certification is issued, an Ed25519 digital signature is generated and permanently linked to the record.
Certification proves the artifact existed at a specific timestamp, that its contents match the recorded hash, and that the record has not been tampered with since issuance. Artifacts can be independently verified without trusting CertifiedData directly.
How to verify an artifact
- 01Locate the artifact entry and note its SHA-256 artifactHash.
- 02Download or hash your local copy of the artifact using SHA-256.
- 03Compare your computed hash to the recorded artifactHash. A match confirms integrity.
- 04For certified entries, follow the verification link to validate the Ed25519 signature.

How to use this registry
01
Find an artifact
Browse by category, filter by certification status, or search by keyword or tag.
02
Check certification
Green = Ed25519 signed certificate issued. Grey = registered, not yet certified. Both are real entries — certification adds machine-verifiable proof.
03
Verify integrity
Compute the SHA-256 hash of your copy and compare it to the recorded artifactHash. No trust required.
04
Use for compliance
Reference the certificate ID in audit logs, regulatory filings, and governance documentation.
Register your artifact
From registered to Ed25519 certified in one API call
Use POST /v1/registry to register an artifact, then POST /v1/registry/:id/certify to issue a signed certificate and flip the badge from grey to green.
