Write-Once-Read-Many (WORM) refers to data storage systems where information can be written once but read multiple times without modification. This concept is crucial for ensuring data integrity and security.In blockchain technology, WORM characteristics are essential. Once a transaction is recorded on the blockchain, it cannot be altered or deleted, guaranteeing that the history remains intact. This immutability protects against fraud and manipulation, allowing users to trust the accuracy of the data.WORM also supports efficient data retrieval. Since the information is stored in a permanent, unchangeable format, it can be accessed repeatedly for verification or analysis. This feature is particularly important for audits and regulatory compliance, as it provides a reliable record.Overall, WORM enhances security and trust in decentralized systems by ensuring that data remains unchanged while allowing for continuous access and transparency.
