What is an AI artifact registry?

An AI artifact registry is a public, machine-readable index of AI artifacts — synthetic datasets, models, and AI outputs — each with a recorded SHA-256 fingerprint, certification status, and independent verification link. The CertifiedData Registry allows anyone to browse, search, and verify registered artifacts without an account.

How do I verify an artifact in this registry?

To verify an artifact: (1) locate the entry and note its SHA-256 artifactHash; (2) download or hash your local copy of the artifact using SHA-256; (3) compare your computed hash to the recorded artifactHash — a match confirms integrity; (4) for certified entries, follow the verification link to validate the Ed25519 signature. No account is required.

What does 'certified' mean in this registry?

A certified registry entry has been issued an Ed25519 digital signature by CertifiedData. This signature covers the full certificate payload including the artifact's SHA-256 fingerprint, generation metadata, and issuance timestamp. Any modification to either the artifact or the certificate breaks verification. Uncertified entries have recorded fingerprints but no signature yet.

Q: What is this registry?

The CertifiedData Registry is a public index of AI artifacts that have been registered and optionally certified. Each entry records a SHA-256 artifact fingerprint at registration time. When certification is issued, an Ed25519 digital signature is permanently linked to the record. Artifacts can be independently verified without trusting CertifiedData directly.

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.

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.

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.

Key definitions

AI artifact registry
Dataset verification: Dataset verification is the process of confirming that a dataset or artifact matches its recorded SHA-256 fingerprint and that the issuer's Ed25519 signature is valid where a certificate exists. It provides cryptographic verification of artifact hashes, dataset fingerprints, and issuer signatures without requiring a platform account.
SHA-256 fingerprint: A SHA-256 fingerprint is a deterministic 256-bit hash of a dataset or artifact file. Any change to the file produces a different fingerprint, which breaks the link to its certificate or registry record.
Ed25519 certificate: An Ed25519 certificate is a certificate whose payload has been signed using the Ed25519 digital signature algorithm. CertifiedData uses Ed25519 signatures so certificate authenticity can be checked with compact, widely supported public-key verification.

How to use this registry

Find an artifact

Browse by category, filter by certification status, or search by keyword or tag.

Check certification

Green = Ed25519 signed certificate issued. Grey = registered, not yet certified. Both are real entries — certification adds machine-verifiable proof.

Verify integrity

Compute the SHA-256 hash of your copy and compare it to the recorded artifactHash. No trust required.

Use for compliance

Reference the certificate ID in audit logs, regulatory filings, and governance documentation.
