Blockchain on AWS

Easily build scalable blockchain and ledger solutions

AWS provides the simplest way to build scalable blockchain networks and ledger applications for your business

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.


Use Cases


Track and verify transactions with centralized ownership

Manufacturers want to store data from multiple systems into a centralized ledger that accurately tracks the production and distribution lineage of their products. In case of issues manufacturers can quickly trace the root cause of defects and take preventive actions.

HR and Payroll systems often have to track and maintain a record of an employee’s details such as payroll, bonus, benefits, and performance history. By implementing a centralized ledger, customers can easily maintain a complete record of the digital history of their employees in a single place.

Insurance: Insurance applications often need a way to better track the history of claim transactions. Instead of building complex auditing functionality using relational databases, insurance companies can use a ledger database to accurately maintain the history of claims over their entire lifetime.


Execute transactions and contracts with decentralized ownership

Trade: Trade consortiums are looking to reduce time and complexity of cross-boundary payments and asset transfers (letter of credit) by directly transacting with multiple parties such as importers, exporters, insurance, and banks in a decentralized way.

Retail: Consortium of retailers want to partner with banks and third-party loyalty programs to streamline customer reward programs without needing a central entity that processes rewards.

Syndicated loans are ones where a group of banks lend together to a single borrower. In a traditional syndicated loan, banks rely on faxes or emails to share complex information back-and-forth, which delays the process. Groups of banks are looking to execute transactions in a decentralized and trusted way to exchange information quickly and eliminate the need for an intermediary.

AWS Capabilities

Capabilities of ledgers with centralized ownership
Capabilities of blockchain networks with decentralized ownership
 Central, trusted authority owns and manages the ledger, and is shared with any number of parties that are working together
Multiple parties can transact with one another without having to know or trust each other. Each party, known as a member, owns a peer node in the network
Uses an append-only journal that stores every transaction into a block. Blocks are cryptographically-chained together in a sequence and cannot be deleted or modified by the central owner or any other entities.
Committed transactions are stored in blocks and are cryptographically-chained together and cannot be modified. Once a transaction is committed, it is replicated across all members making it impossible to change or delete.
Uses cryptography to create a concise summary of change history. This secure summary, commonly known as a digest, can be used to cryptographically verify the lineage of the data in the ledger.
Each member stores a local copy of the ledger and can independently verify and ensure that the contents of the ledger are accurate. To make any change, members of the network need to validate a new transaction, keeping data across all peer organizations consistent
Entire data history can be easily queried, providing a complete and transparent log of information.
All committed transactions are attributable to one or more entities, providing complete transparency to all members. In permissioned blockchain frameworks, such as Hyperledger Fabric, transparency can be configurable such that only select group of peers can access information.
Ledgers with centralized trust don’t require distributed consensus to execute, allowing them to easily scale up and execute transactions faster than ledgers in common blockchain frameworks.
Removes intermediaries
Each peer organization can initiate a new transaction using encoded application logic. Once a transaction is initiated, it is replicated across all peers in the network, allowing multiple parties to access and validate the information. No intermediaries are needed to act as a liaison between the members, making complex transactions more efficient and less expensive.


Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log ‎owned by a central trusted authority. Amazon QLDB tracks each and every application data change and maintains a complete and verifiable history of changes over time.
