Receipt Timestamp

Definition ∞ A receipt timestamp is a recorded time indicating when a specific event or transaction occurred. In blockchain systems, this refers to the precise moment a transaction is confirmed and added to a block. This cryptographic timestamp provides an immutable and verifiable record of the event’s sequence. It is crucial for maintaining transactional order, ensuring data integrity, and resolving disputes within distributed ledgers.
Context ∞ While a fundamental technical detail, the accuracy and integrity of receipt timestamps are occasionally discussed in crypto news concerning network attacks or consensus mechanism vulnerabilities. Debates can arise regarding the reliance on external time sources or the potential for timestamp manipulation in certain blockchain architectures. Future research focuses on decentralized timekeeping solutions and improved resistance to timestamp-related exploits, enhancing the overall security of transaction ordering.
