A timestamp agreement protocol is a distributed algorithm that enables participants in a network to agree on the chronological order of events or transactions. This protocol ensures that all honest nodes record events with a consistent and verifiable time reference, even in the presence of malicious actors or network delays. It is critical for maintaining the integrity and consistency of distributed ledgers and preventing double-spending.
Context
Timestamp agreement protocols are a core component of many blockchain networks, where they are essential for establishing a reliable ordering of transactions and preventing various attacks. Current research and development focus on improving the efficiency and robustness of these protocols, especially in highly decentralized and asynchronous environments. Advances in timestamp agreement are vital for enhancing the security, scalability, and finality guarantees of future blockchain architectures.
This work introduces a Decentralized Clock Network that separates transaction ordering from consensus, using timestamp agreement to enforce δ-Median Fairness and mitigate front-running.
