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.

  • What is the relationship between Hyperledger Fabric and Hyperledger Composer?
    A: Hyperledger Composer supports the existing Hyperledger Fabric blockchain infrastructure by providing a testing ground to try out Hyperledger Fabric in the business operation so it can be smoothly integrated later.

  • What do we define within the Model File?
    A: Assets (tangible & intangible goods, services or property) and the Transactions related to them as well as the Participants that interact with your business network.

  • What is the relationship between assets, participants and transactions?
    A: Participants can have their access to assets or transactions restricted based on their role in the network or sales/transaction process.

  1. What do we define within the Model File?

Assets, participants, transactions interacting operationally within the organisation’s network as part of the company’s profit structure.

  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

Participants are the buyers/sellers of the assets or other parties within the network that has a stake in the execution of the assets and transactions

  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.

What is the goal of Hyperledger Composer?
The goal of hyperledger composer is to build a valuable blockchain application while minimizing the time spent in building such an architecture by integrating the existing business structure into a particular blockchain model.

What is the relationship between Hyperledger Fabric and Hyperledger Composer?
The composer is a platform/layer within the Fabric to bring the whole fabric to work in an efficient and timely manner

What do we define within the Model File?
Assets,Participants and Transaction are the key part of the Model

What is the relationship between assets, participants and transactions?
They are part of the Business Network Architecture.

@filip I think it is worthy to let you know that the Hyperledger Composer has been deprecated since August 2019 and therefore we won’t be able to play around with it. And I believe this part of the course will now need to be updated to a new industry standard platform that can be use to develop the Fabric.

1 Hyperledger Composer is an extensive, open development toolset and framework to make developing blockchain applications easier. It allows you to model your business network and integrate existing systems and data with your blockchain applications.

2 Hyperledger Composer sits on top of the Hyperledger Fabric and therefore it is a prerequisite that the Hyperledger Fabric has already been created before using the Hyperledger Composer

3 Assets, Participants and Transactions

4 Assets are tangible or intangible goods, services, or properties. Transactions are related to assets. Participants interact with assets thru transactions. Each participantscan be associated with a unique identity, across multiple business networks.
