An application uses encrypted transactional data to record incoming and changing data sets. Which technology does the application use?

The application uses blockchain technology to manage encrypted transactional data effectively. Blockchain is specifically designed to maintain a secure and immutable ledger of transactions. Each record, or block, is linked to the previous one using cryptographic hashes, providing a high level of security and data integrity. When data is encrypted within this system, it ensures that sensitive information remains confidential while still being verifiable by authorized users.

Using blockchain is advantageous for applications that require transparency and traceability in their transactions. Each transaction is recorded chronologically in the blockchain, and once data is logged, it cannot be altered without the consensus of the network participants. This makes blockchain ideal for scenarios where data integrity and security are paramount, such as in financial transactions, supply chain management, and other transactional use cases that involve sensitive data sets.
