About Amazon Qldb
Amazon Quantum Ledger Database (QLDB) was announced by Amazon Web Services in 2018. It was created to address the need for a fully managed ledger database that ensures data integrity and transparency. The service aimed to provide a cryptographically verifiable transaction log, allowing users to track and verify changes to their application data.
Strengths of Amazon QLDB include its immutability, cryptographic verification, and fully managed service. Weaknesses are its limited use cases compared to general-purpose databases and potential performance overhead for certain applications. Competitors include Hyperledger Fabric, R3 Corda, and traditional relational databases with audit capabilities.
