One-click on-chain anchoring for collection archives: SHA-256 file fingerprint + server-side trusted timestamp, chained-hash anchoring, publicly verifiable — trustworthy evidence for registration and circulation
Note: attestation records are kept in the platform's server-side trusted ledger using chained-hash anchoring (each record contains the previous chain hash), so any tampering with historical records is detected by full-chain verification; public verification is available by attestation ID or file fingerprint. Original images and videos are neither uploaded nor anchored — only the fingerprint and registration data are fixed. Attestation fees are collected by the platform with an invoice issued. Integration with judicially qualified third-party blockchain nodes (such as Zhixin Chain or Ant Chain) can be arranged separately; please book through support.

Partner with fully qualified professional institutions and establish assessment review and re-check mechanisms so the process stays standardised and results traceable.
