Proof of Time: A Method for Verifiable Temporal Commitments Without Timestamp Disclosure
Abstract
This paper introduces a cryptographic method that enables users to prove that an event occurred in the past and that a specified amount of time has since elapsed, without disclosing the exact timestamp of the event. The method leverages zero-knowledge proofs and an on-chain Incremental Merkle Tree to store hash commitments. By utilizing the Poseidon hash function and implementing zero-knowledge circuits in Noir, this approach ensures both the integrity and confidentiality of temporal information.
