  • identify the effect of using the "view" access modifier for a function
  • identify the options and templates supplied by Hyperledger Composer Playground to build out business blockchain networks

  • identify the types of rules that can be defined in the access control list (ACL) for a Hyperledger Composer network
  • identify what a smart contract is and contrast it with a traditional contract
  • identify what makes containers much more lightweight than virtual machines
  • initialize the Hyperledger Composer REST API server so that it can be used to interact with a deployed blockchain network
  • install and launch the Ganache tool which instantly spins up a private Ethereum network to help with contract development
  • install, instantiate, and invoke a function on the NodeJS chaincode
  • install tools such as the Composer REST Server and Yeoman to simplify the building of apps for Hyperledger Composer

  • use the configtxgens tool to create the Fabric network's first genesis block and channel
  • use the Hyperledger Composer Playground tool to test different scenarios for a business blockchain network
  • use the selfdestruct function to delete a smart contract from the Ethereum network
  • verify the features implemented in the application by accessing the UI and invoking queries and transactions
  • work with events and use them in smart contracts to log activities
  • write an application in NodeJS that will use admin credentials in order to provision an application user
