AWS Blockchain services provide purpose-built tools to support your requirement. You can use them to build everything from a centralized ledger database that maintains an immutable record of transactions to a multi-party, fully managed blockchain network that helps eliminate intermediaries.
AWS has numerous validated blockchain solutions from partners who support all major blockchain protocols, including Hyperledger, Corda, Ethereum, Quorum, and more. As a result, you can develop blockchain and ledger applications more easily, quickly, and efficiently with AWS. Some useful AWS Blockchain services are as follows:
Amazon Quantum Ledger Database (QLDB) is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log. It has a built-in journal that stores an accurate and sequenced entry of every data change. The journal is append-only, meaning that users can add data to the journal but cannot overwrite or delete it.
Amazon Managed Blockchain is a fully managed service that makes it easy to join public networks or create and manage scalable private networks using Hyperledger Fabric and Ethereum.
