Amazon Web Services (AWS), an Amazon.com company, announced the general availability of Amazon Quantum Ledger Database (QLDB), a fully managed service that provides a high-performance, immutable, and cryptographically verifiable ledger for applications that need a central, trusted authority to provide a permanent and complete record of transactions across industries like retail, finance, manufacturing, insurance, and human resources.
Amazon QLDB offers familiar database capabilities that make it easy to use, and its document-oriented data model is flexible, enabling customers to store structured and unstructured data in the ledger. There are no upfront commitments to use Amazon QLDB, and customers pay for what they use.
Customers looking to implement blockchain technologies are typically trying to accomplish one of two things. Some customers want the immutable and verifiable record of transactions provided by a ledger, however they also want to allow multiple parties to transact, execute contracts, and share data anonymously, without the need for a trusted central authority (e.g. transferring reward points across a network of vendors, or processing transactions that concern a number of different trade and logistics companies).
