Verify a document against its on-chain anchor
When a project is approved, the platform freezes its document set, computes a Merkle root over it, and anchors that root on-chain. Anyone can confirm that a document is the approved, unaltered version — without ever needing access to the platform.
- 1Add the document
Choose or drop the file you want to check. It is hashed entirely in your browser and is never uploaded to any server.
- 2We compute the hash
The tool computes the SHA-256 of the file — the same cryptographic method used to build the Merkle root anchored at project approval.
- 3Compared on-chain
The result is checked against the on-chain anchor of the approved document set. A match confirms the document is genuine and unaltered.
A mismatch is meaningful. If a document does not match an anchored set, it is not the approved version — regardless of where it was obtained. Restricted documents such as title deeds are never released, but their hash is published so their integrity can still be verified.
