Temporal Proof

Definition

Temporal proof refers to a cryptographic method used to establish that a specific piece of data existed at a particular point in time. This is achieved by embedding a timestamp or a reference to a block in a blockchain, which inherently provides an immutable and verifiable record of creation or modification. The proof confirms the data’s existence and integrity at that moment, preventing retroactive alteration. It is a mechanism for verifiable record-keeping and data authentication.
