Select a file to record as evidence. ProofLedger computes a one-way SHA-256 fingerprint (not your file) and creates an immutable evidence record with verifiable timestamps suitable for audit or dispute review. Evidence records are final once created.
No evidence record created yet.
Pre-loss temporal authority documentation is the practice of recording evidence at the moment of creation, cryptographically fixing its state in time before disputes, incentives, or claims exist. These systems establish when a record existed and what state it was in using repeatable, tamper-evident procedures that allow independent verification without reliance on the recording system itself.
ProofLedger is an implementation of this approach, designed for high-liability environments where contemporaneous, pre-loss records must remain verifiable long after they are created.
