SOURCE 0 - THE CERTIFICATE THAT CERTIFIES ITSELF

A market has formed around cryptographic certification of synthetic datasets — SHA-256 fingerprints, Ed25519 signatures, publicly verifiable registries. The better providers state plainly what this proves: integrity and authenticity of the certificate, not generation quality. That honesty does not close the gap that matters under Article 10 of the AI Act, especially where the same platform both generates the data and signs its own certificate.
