Proof of the archive

VERIFY A SEALED PLATE

Every scanned plate in this archive is fingerprinted with SHA-256 the moment it is received. The fingerprints of a scan session are folded into a single Merkle root, and that root is published to a public blockchain. Anyone can confirm that a given plate existed in this house at that date — without ever seeing the plate.

The plate itself is never returned by this page. Sealed transmissions open only to approved members of 6th Dan and above holding an active membership of the Society.
