- HyperLedger Composer goal is to accelerate time to value, and make it easier to integrate your blockchain applications with the existing business systems.
- HyperLedger Composer is a layer on top HyperLedger Fabric and supports the existing Hyperledger Fabric blockchain infrastructure and runtime.
- 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.
- They all interact with each other. 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.

What is the goal of Hyperledger Composer?
To accelerate time to value by making it easier to integrate blockchain applications with existing business systems.
What is the relationship between Hyperledger Fabric and Hyperledger Composer?
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.
What do we define within the Model File?
Assets, Participants and transactions.
What is the relationship between assets, participants and transactions?
Assets are the products or services I.e Houses (real estate) Participants are the buyers or users and Transations are the sales/consumers.

- The goal is to make developing of blockchain applications easier and integrate with existing business as well as acceleration of time to value (TTV). Which is the time that takes for a customer to realize value from your product.
- The hyperledger composer supports the hyperledger fabric infrastructure and runtime that are supported by pluggable blockchain in the network.
- The Model File is the way assets, transactions and participants are interacted on the network.
- In a business network the participants have restricted access to transactions based on their role such as buyer, seller or realtor. Assets can be traded by using a simple user interface application created by the realtor.

The goal of Composer is to allow businesses to quickly integrate their business systems and data with the blockchain so that they can achieve efficiencies in a short space of time.

Hyperledger Composer is a simplified version of Fabric that is built on a layer on top of the Fabric code. It supports pluggable blockchain protocols to ensure transactions are validated on the blockchain network.
3.The model file defines the structure of the resources that will be stored on the ledger or processed as transactions.
- Participants are permissioned users of the network that are allowed to interact with the products (assets) of the business. The transactions are the record of that interaction.

@filip: They guys at Hyperledger Composer have deprecated the project in Aug 2019 and now recommend to use Hyperledger Fabric which is now in release v2.0. Could you update the course and do videos on Fabric instead?

What is the relationship between assets, participants and transactions?
Participants have access to transaction related to them according their role. Asset is an intangible good or service part of the transaction.

Hyperledger Composer supports Hyperledger Fabric infrastructure. It makes sure that transactions are validated according to individual policies for each business connected to the platform.
-
Within the model file you define transactions. These transactions interact with the assets of your business. Participants can also be defined within the model file.
-
Assets, participants, and transactions are three main components that make a business work. Without any of them you do not have a functioning business. Participants (customers and employees) transact (buy and sell) using different assets that the business or the customers themselves own.

Composer is an sdk to make developing Hyperledger bc applications easier.

In the model file we need to define transactions which can interact with assets.
4
A realtor can setup an Hyperledger bc to manage real estate listings, negotiations between owners and buyers, transactions and updating municipality’s ledger.
Assets are the buildings/parcels, participants the buyers and homeowners, transactions the final buyings and creating and closing listings.

composer runs on top of the fabric and supports the existing infrastructure - What do we define within the Model File?
model file is the way to build a network or collection of sub networks where particular business or groups can segregate to function on the blockchain - What is the relationship between assets, participants and transactions?
assets are particular items in question that have transactions connected with them. participants are individuals who are working with assets (buying, selling, trading, etc.) and transactions are basically those exchanges

- The goal of Hyperledger Compose is to make developing blockchain applications easier, by accelerating the speed of developing and making it easier to integrate with existing business systems.
- Hyperledger Composer is another layer that makes the use of Fabric more user friendly and easier to implement while at the same time supporting the consensus protocols and runtime of Fabric to make sure transactions are approved.
- The Model File consists of assets, participants and their transactions.
- Transaction control varies based on the permission level of the participant and the participants permission level varies based on their relationship with an asset.
