  1. What is the goal of Hyperledger Composer?
    – to accelerate time to value, and make it easier to integrate your blockchain applications with the existing business systems

  2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    – Hyperledger Composer supports the existing Hyperledger Fabric blockchain infrastructure and runtime, which supports pluggable blockchain consensus protocols to ensure that transactions are validated according to policy by the designated business network participants.

  3. What do we define within the Model File?
    – your current business network, containing your existing assets and the transactions related to them; assets are tangible or intangible goods, services, or property. As part of your business network model, you define the transactions which can interact with assets. Business networks also include the participants who interact with them, each of which can be associated with a unique identity, across multiple business networks.

  4. What is the relationship between assets, participants and transactions?
    – they are all components of the business system, each having their own role and requirements and ultimate interaction points in the system
