Clock Synchronization

Definition ∞ Clock synchronization is the process of coordinating time across multiple independent computing devices within a network. In blockchain systems, accurate time alignment among nodes is vital for maintaining the correct order of transactions and validating blocks. Discrepancies in timing can lead to consensus failures, double-spending issues, or other protocol vulnerabilities. Protocols often incorporate mechanisms to achieve and preserve a consistent global time reference.
Context ∞ The importance of clock synchronization is frequently discussed in technical news regarding blockchain security and consensus mechanisms. Any reports of network forks or transaction ordering anomalies often relate to underlying timing issues. Advanced synchronization methods are continually researched to enhance the reliability and security of distributed ledgers.
