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.

[BERGLUND]

1. The goal is to simulate a network with applications, participants etc. without the need of programming skills in the hyperledger fabric.
2. HLC is a simplification layer on top of HLF.
3. Assets, participants and transactions.
4. assets = goods, services, or property
   participants use transactions to exchange assets

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.

[Nomarsky]

1. The goal is to integrate the blockchain to the existing business units.

2. Composer is used to model and adapt the functions of Hyperledger like: transactions, participants, access, queries, etc.

3. Assets, users and transactions.

4. The assets belong to participants and these make transactions with their assets.

1. What is the goal of Hyperledger Composer?
   – The goal of Hyperledger Composer was to make developing blockchain applications easier and to accelerate time to value, and make it easier to integrate new blockchain applications with the existing business systems and to be able to accomplish this in weeks instead of months

2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
   – Hyperledger Composer supports the existing Hyperledger Fabric blockchain infrastructure and provides a way for business users to quickly understand the model and for developers to get started quickly

3. What do we define within the Model File?
   – Assets, participants, and transactions are defined within the model file.

4. What is the relationship between assets, participants and transactions?
   – Assets, Participants, and transactions make up the business network model. For example in a real estate model, the assets are the houses for sale and the listings. The participants are the buyer, sellers, and realtors. And the transactions consists of the actual buying and selling the houses and creating and removing the listings

• What is the goal of Hyperledger Composer?
• What is the relationship between Hyperledger Fabric and Hyperledger Composer?
• What do we define within the Model File?
• What is the relationship between assets, participants and transactions?

1.- The goal is to increase the speed of development of blockchain applications and accelerate time to value
2.- Hyperledger composer is a user friendly layer built on top of Fabric
3.- Assets, participants and transactions
4.- Assets are good, services, or properties.
Participants interact with assets thru transactions.

[ThreeHeadsUp]

1. the main goal is to accommodate easy integration of (existing) blockchain applications with (existing)business systems, without need to redo the existing business system, thereby keeping them intact
2. The composer is a layer built on top of the hyperledger fabric infrastructure, used to seamlessly and easily garner the power of hyperledger fabric and integrate it into a project
3. the model file defines assets, participants and transactions pertaining to the business network
4. each will have different relationships between them, tying them together, assets can be viewed basically as the “WHAT”, the participants as the “WHO” and the transactions as the “HOW/WHY”; when compiling all together a valid, reasonable and understandable sentence (output) should be formed

[Tiffany]

1. Hyperledger Composer is an extensive, open development toolset and framework to make developing blockchain applications easier.
2. Hyperledger Fabric is the foundation upon which private blockchains are built. Composer is the application that creates the framework to build on the Hyperledger Fabric.
3. The things in which you want to model, like assets, particpants and transactions.
4. assets, participants and transactions separate the what from the who and the how and the ways in which they interact.
