In this course, you will explore the definition and testing of a blockchain app for recording transactions on supply chain assets. In the cloud-based Hyperledger Composer environment, examine syntax of the CTO modeling language. Recall the transaction processing script and identify access control list (ACL) rules for a Hyperledger Composer network. Next, test business blockchain network scenarios in a Composer Playground test environment using the Composer Playground tool and identify options and templates to build business blockchain networks: identifying assets, participants, and transactions involved in a supply chain’s blockchain network. Generate identities for Hyperledger Composer network participants and create assets and participants involved in transactions. Perform tests of permissions defined in Composer’s ACL file and confirm the logic of the transactions, then invoke transactions using Composer Playground UI and confirm defined permissions. Export the blockchain business network defined in Hyperledger Composer Playground, which can later be used to deploy the network to another Hyperledger Fabric network. The concluding exercise lists definition files for a Hypercomposer blockchain application and connects participants to the test environment.
