Blockchain
Developing blockchain and ledger applications is simpler, faster, and more efficient with AWS. AWS provides purpose-built tools to support your distinct blockchain needs, whether you need a centralized ledger database that maintains an immutable and cryptographically verifiable record of transactions, or a multi-party, fully managed blockchain network that helps eliminate intermediaries.
