  • What is the goal of Hyperledger Composer?
    To accelerate THE time to value, and make it easier to integrate blockchain applications with the existing business systems’
  • What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    Composer is a tool built to accelerate developement of Hyper ledger. It is a layer on top on Fabric that can be executed onto the already constructed fabric construction.
  • What do we define within the Model File?
    It depends on the business, but the example is a realtor, which is assets, people and tx.
  • What is the relationship between assets, participants and transactions?
    The ralationship is the tx
  1. What is the goal of Hyperledger Composer?
    To make it easier to implement blockchain solutions with existing systems. It should be noted that as of today, Composer is no longer being developed. It is recommended the you use Hyperledger Fabric v1.4 instead.

  2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    Composer supports Fabric’s pluggable blockchain protocols to ensure that txs are validated by the designated business network participants.

  3. What do we define within the Model File?
    Assets, participants and transactions.

  4. What is the relationship between assets, participants and transactions?
    Their unique interactions; usually designated by authorization within the business.

1.What is the goal of Hyperledger Composer? A tool to build a business network

2.What is the relationship between Hyperledger Fabric and Hyperledger Composer? Composer is a layer on top of Fabric. You can create assets & participants in Composer and transact them on the existing Fabric network

3.What do we define within the Model File? Assets, participants, and transactions

4.What is the relationship between assets, participants and transactions? Asset is the object for exchange, participants are the exchangers, the transaction is the action they want to take for that exchange

  1. What is the goal of Hyperledger Composer?
    It makes developing blockchain applications easier. And by accelerating time to value means you can integrate new applications to existing infrastructure in days rather than weeks.

  2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    It supports the Hyperledger Fabric framework

  3. What do we define within the Model File?
    The existing assets, participants and the transactions relating to them.

  4. What is the relationship between assets, participants and transactions?
    Assets are objects to be exchanged
    Participants carry out exchanges
    Transaction is the desired action participants want to carry out.

The relationship between the three are based on the defined & allowable transactions set by the business network model. Depending on the defined role of the participant, they are allowed to transact with the assets in a certain fixed way.

3. What do we define within the Model File?

Quite close sir, in the Model File you define the behave and rules for Assets, participants, transactions.

4. What is the relationship between assets, participants and transactions?

Assets : tangible or intangible goods, services, or property.
Participants : A permissioned network user, each can be associated with a unique identity, across multiple business networks based on their role.
Transactions : An action applied on an asset based on an agreement protocol from 2 or more participants .

Hope this gives you a clear picture of the subject.

  1. What is the relationship between assets, participants and transactions?

Assets are the goods, service or property sold by the business

Transactions is the process of exchanging and transacting the assets

  1. Permits a quicker planning and deployment of blockchain solutions

  2. Hyperledger Composer is a framework for the creation of Hyperledger fabric blockchain applications. By the way, an alert in the article says that Composer is deprecated and recommends using Hyperledger Fabric 1.4+ : https://github.com/hyperledger/composer/blob/master/README.md

  3. Assets, participants and transactions. Hence, the model of the business network we are trying to find a Hyperledger Fabric solution for.

  4. Assets: Are the things the business network (=the participants) is trading with. The participants are trading with these assets (=transactions take place). The transactions can be seen as the relation between participants and assets.

  • What is the goal of Hyperledger Composer?
    The goal is to make it easier to blockchain apps into existing business systems so money or value is realized sooner.

  • What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    Composer is apart of Fabric and makes it easy to add necessary pieces to the business environment, like users, assets and transactions.

  • What do we define within the Model File?
    All the business components, like users, transactions and assets along with the relationships of which parts interact with one another.

  • What is the relationship between assets, participants and transactions?
    The business model is made up of varying pieces to different transactions so the relation is that these are all pieces that interact and transact with each other.
