    At the heart of every blockchain application is one or more chaincodes. So a chaincode should be bug-free and tested before it is deployed and instantiated. You can use Blockchain App Builder to generate complex chaincodes from a simple configuration file and assets specification in TypeScript for node.

    With the specification file you can specify multiple asset definitions and behaviors. You can then generate and test your chaincodes either on your local machine by using a preconfigured instance of Hyperledger Fabric inside Blockchain App Builder, or by connecting to your Oracle Blockchain Platform network. The Blockchain App Builder supports the full development lifecycle either using a command line interface or as an extension for Visual Studio Code.

In previous releases Kafka was the only available consensus type of orderer. As of this release, Raft consensus is supported and Kafka is no longer supported. With this feature, orderers from multiple organizations can join a cluster, and channels can use different Raft orderer clusters to distribute load and provide better scalability.
