Understanding the Amazon Quantum Ledger Database (QLDB)

The Amazon Quantum Ledger Database (QLDB) is a fully managed ledger database designed to provide a transparent, immutable, and cryptographically verifiable transaction log. Unlike traditional databases, QLDB meticulously tracks every change made to your data, creating a permanent and auditable history. This is achieved through a combination of cryptographic hashing and an immutable journal, ensuring that data cannot be altered or deleted without detection.

Amazon Quantum Ledger Database (Amazon QLDB) is a fully managed ledger database that maintains a complete, immutable record of every change committed to the database. As transactions are committed to the database, they are appended to a transaction log called a journal and are cryptographically hash-chained to the previous transaction.

At its core, QLDB acts as a single source of truth, eliminating the need for complex reconciliation processes often associated with traditional databases. This is particularly beneficial for applications requiring high levels of data integrity, such as financial transactions, supply chain management, and regulatory compliance.

The newest edition to Amazon s database stable, Amazon Quantum Ledger Database is a centralized blockchain service, providing users with an absolute, cryptographically verifiable log. Amazon QLDB creates permanent, unchangeable records of transactions, and can be used to store data for apps that require centralized, trusted authority.
