Blockchain technologies are often used to solve two types of customer needs. In the first case, multiple parties work with a centralized, trusted authority to maintain a complete and verifiable record of transactions. An example is a retail customer looking to connect its suppliers with a centralized ledger that maintains a transparent and verifiable history of information related to the movement of a product through its supply chain. In the other case, multiple parties transact in a decentralized manner without the need for a centralized, trusted authority. An example is a consortium of banks and export houses looking to perform cross-boundary transfer of assets (e.g. letter-of-credits) amongst each other, without a centralized authority acting as a liaison.

If you need a centralized ledger that records all application data changes, and maintains an immutable record of these changes, AWS provides a ledger database. This database is high-performance, immutable, and cryptographically verifiable, eliminating the need for building complex audit tables or setting up blockchain networks. If you need the immutable and verifiable capability provided by a ledger, and also want to allow multiple parties to transact without a trusted central authority, AWS provides a fully managed, scalable blockchain service. AWS blockchain service makes it easy to setup, deploy, and manage scalable blockchain networks, eliminating the need for you to rely on expensive consulting implementations.
