[Bulmers]

1] To accelerate time to value, and make it easier to integrate your blockchain applications with the existing business systems
2] Hyperledger Composer supports the existing Hyperledger Fabric blockchain infrastructure and run-time
3] Assets, Participants, and Transactions
4] Participants are members of a business network and may own assets and submit transactions.
Transactions are a mechanism by which participants interact with assets

[diogozas]

[Mark]

1. What is the goal of Hyperledger Composer?
   To make it quicker and simpler to integrate your blockchain applications with your legacy business systems.
2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
   Hyperledger Composer is a framework for modelling blockchain business networks and deploying in Hyperledger Fabric.
3. What do we define within the Model File?
   Assets, participants, and transactions.
4. What is the relationship between assets, participants and transactions?
   Assets are tangible or intangible goods, services, or property. Participants conduct the transactions utilizing the assets within the business network model of Composer.

[begood]

1. To develop use cases quickly and reduce time to develop solutions
2. Composer is a layer on top Fabric which easily, quickly create assets, participants. Fabric is the main protocol.
3. Assets, participants, and TX
4. Assets = Products, properties, listings, etc
   Participants = Owners, buyers, customers, users, etc
   Transactions = Anything of value that is being exchanged/traded between participants.

[Woodz]

1. The goal of Hyperledger Composer is to integrate blockchain into the existing business systems relatively fast.
2. Hyperledger Composer supports Hyperledger Fabric and is a layer on top of it, which allows pluggable blockchain consensus protocols to validate transactions according to the policy.
   3.Within the Model File there are assets, participants and transactions.
3. Assets, participants and transactions are all a part of a business model network that interact with each other. In this case asses are houses and listings, participants are buyers and homeowners and transactions represent the transfer of value.

[Ho11and]

1. To accelerate integration of the Hyper ledger block chain with existing systems.
2. Composer is the development tool to Fabric
3. Assets, participants and transactions
4. The participants exchange assets which create transactions.

[LeoSp22]

1. The main goal is to make it easier, faster and therefore more efficient the entire process of developing and implementing a blockchain solution suitable to the business needs.
2. Composer lays on top of the Fabric infrastructure and is actually a “simplified” version through which it is possible to use pre-programmed protocols to build a solution easily and properly.
3. Is a file build in .cto format which is used to define assets, participants and transactions on the network.
4. It depends on the configuration, however in general we can imagine that assets are the elements that are transferred to/from participants through transactions, so that all the parts of the business model are synchronized.

[KryptoDr]

1. Hyperledger composer is a layer on top of Hyperledger fabric. That means some rules and definitions are already implemented for the user/business owner. With composer as a layer on top of Hyperledger fabric it is easier to implement the blockchain application in the current business system and the developing process is faster.

2. As I said before Composer is a layer on top of Fabric. That means some things are already defined and implemented.

3. In a model file elements such as assets, transactions, participants etc. are defined

4. Assets, participants and transactions are stored in the model file. Assets can be everything which has a value (data, cryptocurrency, property). Participants can interact with the assets (e. g. buy, sell). Transactions are created between participants when the asset is moved from one participant to another one.

[bitbooz]

1.Hyperledger Composer is an extensive, open development toolset and framework to make developing blockchain applications easier. The primary goal is to accelerate time to value, and make it easier to integrate blockchain applications with the existing business systems.

2. Hyperledger Composer supports the existing [Hyperledger Fabric blockchain] infrastructure and runtime, which supports pluggable blockchain consensus protocols to ensure that transactions are validated according to policy by the designated business network participants.

3.Assets, transactions and participants.

4.Everything is stored in the model file. Example:
Assets =Homes
Participants= Buyers and sellers
Transactions= Whats sold

[Andres]

With the composer is possible to model a business network, and is possible to integrate existing systems and data with BlockChain apps.
2.
Composer supports the existing Hyperledger Fabric infrastructure and runtime, which supports pluggable blockchain consensus protocols.
3.
The structure of the business network.
4.
Assets, participants and transactions are in the same business model, connected through the network.

[Rhonda]

1. A framework or toolset that enables the user to quickly model a use-case that would run in Hyperledger blockchain
2. Fabric is the actual code that is running on the Hyperledger Blockchain. Composer is a quick toolset to develop high level code to determine if a Hyperledger solution is feasible.
3. Assets, participants, and transactions
4. Participants are the people who would use the Blockchain. Assets are the "things’ whose ownership would be transferred between the participants. Transactions are the actions taken between the participants, such as Buy/Sell, Give/Receive, etc.
