Amazon Managed Blockchain , says the company, scales to support thousands of applications and millions of transactions using popular open source frameworks like Hyperledger Fabric and Ethereum. It enables users who want to allow multiple parties to execute transactions and maintain a cryptographically verifiable record of them without the need for a trusted, central authority to quickly set up a blockchain network spanning multiple AWS accounts.
"Customers want to use blockchain frameworks like Hyperledger Fabric and Ethereum to create blockchain networks so they can conduct business quickly, with an immutable record of transactions, but without the need for a centralized authority," says Rahul Pathak, General Manager, Amazon Managed Blockchain at AWS. "However, they find these frameworks difficult to install, configure, and manage."
"Amazon Managed Blockchain takes care of provisioning nodes, setting up the network, managing certificates and security, and scaling the network. Customers can now get a functioning blockchain network set up quickly and easily, so they can focus on application development instead of keeping a blockchain network up and running."
The service is aimed at businesses like finance, logistics, retail, and energy that need to perform transactions quickly across multiple entities. To use it, says the company, customers simply choose their preferred framework (Hyperledger Fabric is supported at launch with Ethereum support coming later this year), add network members, and configure the member nodes that process transaction requests, while Amazon Managed Blockchain takes care of the rest.
Amazon Managed Blockchain also provides simple APIs that allow users to vote on memberships in their networks and to scale up or down more easily. It offers a range of instances with different combinations of compute and memory capacity to give customers the ability to choose the right mix of resources for their blockchain applications.
Amazon Managed Blockchain secures certificates for access control using AWS Key Management Service technology, eliminating the need for customers to set up their own secure certificate storage.
