Amazon has launched two new services, namely Amazon Quantum Ledger Database (QLDB) and Amazon Managed Blockchain. QLDB is a ledger database that provides transparent and immutable log of transactions. These logs are cryptographically verifiable and a central trusted authority administers the changes that are recorded on chain.

Similarly, Amazon Blockchain is another product that allows users to manage a scalable blockchain network. The product is auto-scalable and adjusts as per the needs of specific applications. The solution can manage certificates and summon new users to the network.

Andy Jassy, the CEO of Amazon Web Services, has stated that the product will be flexible and scalable. And, the users will have a robust set of APIs for making modifications to the ledger database. Due to the underlying blockchain technology, the change history will be immutable.
