The Method

Orphograph is documented in full — not as marketing, but as defensive prior art. Each page below describes one part of how a file becomes a Bitcoin-anchored timestamp, and what that timestamp does and does not prove.

• Architecture of the protocol

  Client-side hashing, multi-calendar OpenTimestamps aggregation, Bitcoin commitment, and the structural privacy contract.

• What a Bitcoin block actually attests to

  What it means, precisely, for a fingerprint to be committed to a block — and why that ordering can't be quietly rewritten.

• Folder anchoring by Merkle root

  How a whole folder of files collapses to a single root so one anchor covers many files at once.

• Why filenames are not stored

  The privacy reasoning: only the fingerprint travels; names, paths, and contents never leave your device.

• Why Bitcoin-anchored hashes carry evidentiary weight

  How a timestamp functions as evidence — and the honest limits of that claim.

• Legal recognition of blockchain timestamps

  US and EU citations on the recognition of electronic and blockchain-based timestamps.

• The 100-line verifier, annotated

  The open-source verifier read line by line — proof that your receipt checks against Bitcoin without trusting us.
