Building a blockchain application in Java using Amazon Managed Blockchain

This post demonstrates how to set up a blockchain application written in Java to read and write data to Managed Blockchain using the Fabric Java SDK. The Java SDK allows customers with applications written in Java to integrate blockchain support with their existing codebase. This makes it easier to handle rich data structures and complex business logic before writing records to the blockchain. You can also integrate Managed Blockchain using the Fabric Node.js SDK. For more information, see Building serverless blockchain application with Fabric Node.js SDK.
