standards of evidence integrity

Records can be independently timestamped by DigiCert — proving exactly when each record was created. Available on select tiers.
Cryptographic Hash Chain
Each record cryptographically links to the previous one. Any tampering — anywhere in the chain — is mathematically detectable.

Anyone can independently verify the integrity of your vault entries using our public verification tool — no account required.
