Hyperledger Composer Basics - Reading Assignment


#22

What is the goal of Hyperledger Composer?

  • to accelerate time to value, by making it easier to integrate blockchain applications with the existing business systems.
  • To rapidly develop use cases and deploy a blockchain solution in weeks rather than months.
  • model our business network and integrate existing systems and data with our blockchain applications.

What is the relationship between Hyperledger Fabric and Hyperledger Composer?

Hyperledger Composer simplifies application development on top of the Hyperledger Fabric blockchain infrastructure.

What do we define within the Model File?

Assets, Participants, Transaction and Events.

What is the relationship between assets, participants and transactions?

Participants create a transaction to exchange assets.

  1. What is the goal of Hyperledger Composer?
    Its another layer on top of Hyperledger Fabric and provides the programmer with frameworks and toolset to build easier on top of hyperledger fabric.

  2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    Hyperledger Composer is on top of Fabric, and supports the existing Hyperledger Fabric blockchain infrastructure and runtime.

  3. What do we define within the Model File?
    In the business network model, you define the transactions which can interact with assets.

  4. What is the relationship between assets, participants and transactions?
    Assets are dealt with by participants via transactions.


#24
  • What is the goal of Hyperledger Composer?

To rapidly model the organization processes.

  • What is the relationship between Hyperledger Fabric and Hyperledger Composer?

I understand composer as a tool to configure fabric.

  • What do we define within the Model File?

Assets, transaction rules, participants and roles.

  • What is the relationship between assets, participants and transactions?

Participants create transactions to transfer and exchange the assets.

  1. Hyperledger Composer is a framework to make developing applications easier on Hyperledger Fabric.

  2. Composer sits above Fabric to facilitate developing applications.

  3. The Model File is composed of assets, participants and transactions.

  4. The relationship between Model File components is defined by the other elements (Transaction Functions, Access Control Rules and Query Definitions) to create the overall Business Network Definition.
