Independent verification
Check the evidence. No account required.
Paste a BoardWalk receipt or open the JSON file. Your browser checks its signature locally and shows the recorded counts, acceptances, and source references.
A valid signature confirms the receipt has not changed since it was issued. Review the underlying source evidence before accepting the claim.

How to verify a shared export
Deck and trail exports include a receipt file. Compare the first twelve characters of the signing-key fingerprint shown in the export with the fingerprint shown after verification.
The governed-receipt/v1 format uses Ed25519 over a canonical JSON body. The browser recomputes the fingerprint from the public key that signed the receipt.
