Hyperledger Composer Basics - Reading Assignment

#42

One. It’s goal is to make it easier to build and implement business systems on hyper ledger fabric.
Two. Composer is a tool that allows for faster and easier building on fabric.
Three. The subnetwork that needs to be be built for a particular business or a group of businesses in order for apps toRun effectively on the block chain.
Four. Assets will have transactions related to them. Participants are those authorized to interact with the data regarding assets and transactions.

(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? -Composer supports the Fabric blockchain infrastructure and runtime.

(3) What do we define within the Model File? - The sub network that needs to be built for a particular business or group of businesses in order for applications to run effectively on the blockchain.

(4) What is the relationship between assets, participants and transactions? - They are parts of the business model that must work together in a blockchain environment to make the business achieve its purpose.

  1. What is the goal of Hyperledger Composer?
    To make blockchain applications easier and quicker to develop.
  2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    Fabric is an existing blockcahin and Composer supports it.
  3. What do we define within the Model File?
    By the looks of it ‘countable’ entries / database as in the example - assets, participants, transactions etc.
  4. What is the relationship between assets, participants and transactions?
    These all live in the same file - Model File.

  2. hyperledger composer is an additional layer to hyperledger fabric. it allows to compose blockchain applications easier and faster
  3. transactions, participants and assets
  4. 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.

  1. Offer a framework (skeletal system) for your blockchain network implementation
  2. Composer can be seen as a skeletal system when you add function using Fabric as they are using the same consensus mechanism
  3. Assets , Participants and Transactions
  4. They interact and exchange value
