Blockchain Document Integrity

Verify a document fingerprint

Confirm that a document matches the SHA-256 fingerprint recorded on the blockchain by a TMSDASH anchor. Enter the anchor's transaction hash or fingerprint, then choose the document — it is hashed in your browser and never uploaded.

Verification reads the blockchain on either network — no wallet, no signature, no transaction is required.

Signed in or not, anyone with the reference can verify — no account needed.

How verification works

  1. Choose the network — Base Sepolia (testnet) or Base Mainnet — then enter the anchor's transaction hash or its SHA-256 fingerprint.
  2. TMSDASH finds the anchor and independently confirms the fingerprint exists on the blockchain.
  3. Choose the document file — its fingerprint is computed in your browser and compared to the anchor.

This evidence report demonstrates tamper evidence: it shows whether the anchored data changed after its SHA-256 fingerprint was recorded on the blockchain. It does not prove that the original document contents were truthful, accurate, or complete.
