Immutability gives investigators a stable historical record. New information can append another version while prior states remain available, making it possible to reconstruct what a system knew and how it behaved at an earlier time.
A useful design protects ordering, timestamps, integrity and retention rather than relying only on an application promise not to edit rows. Access controls and cryptographic verification can strengthen confidence that the evidence has not been altered.

Frequently asked questions
