QLDB

Amazon Quantum Ledger Database (QLDB) is a managed ledger database management system. Its core storage architecture is an immutable and cryptographically verifiable transaction log. Unlike a blockchain DBMS where trust is distributed among participants, QLDB uses a centralized trusted authority (i.e., Amazon).
