Advanced Timestamping: Synchronization and Consistency in Public Information Systems

Abstract

This paper studies the aspects of Distributed Ledger Technology (DLT) related to deciding how to order incoming ledger data records under the requirement to provide transparency and security in public information systems, particularly in the context of e-government. The study addresses the challenges of synchronizing ledger replicas across distributed systems, ensuring consistency and reliability in data storage and retrieval. The research highlights the importance of maintaining a unified ledger state, which is crucial for decisionmaking processes in the public and social sectors. The proposed solution combines Lamport's clock algorithm with wave algorithms to overcome the limitations of traditional timestamping methods, such as the duplication of timestamps for concurrent events. This approach ensures that each event in the distributed ledger is uniquely identified, thereby enhancing the system's robustness and efficiency.
