Hyperledger Composer Basics - Reading Assignment

[Mesiah]

3 A: define the transactions which can interact with assets also the participants who interact with them, each of which can be associated with a unique identity, across multiple business networks.

4 A: Assets: products or goods
Participants:buyers and sellers
Transactions buying or selling between two parties

hi
i assume, they (the relationships) are defined in the model-file(s)
have a good time.

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 view of the subject, keep learning!

If you have any doubt, please let us know so we can help you!

1. To rapidly deploy use cases in weeks rather than months (as a model)

2. Once a use case is developed and tested in composer modelling, it can be fully developed using the full Fabric blockchain

3. Model File defines the Assets, Participants and Transactions of the business network.

4. ASSETS: are tangible or non tangible goods, services and/or property stored in registries of the business network. PARTICIPANTS: are members of the business network and can own ASSETS and submit TRANSACTIONS (typical of that business). ASSETS and PARTICIPANTS state are stored on State database by all peers, while TRANSACTIONS are stored on the Ledger on all peers.

What is the goal of Hyperledger Composer?
To reduce the difficulty in developing blockchain solutions for a business and allow quick and simple integration with the hyperledger fabric.

What is the relationship between Hyperledger Fabric and Hyperledger Composer?
The hyperledger composer interacts with the hyperledger fabric as a development toolkit for blockchain solutions on the hyperledger fabric.

What do we define within the Model File?
Assets, participants (buyers, seller etc.) and transactions.

What is the relationship between assets, participants and transactions?
Assets are the entities being transacted, participants are the parties involved in the transactions and the transactions are a record of the activity between the participants when they exchange assets.

1. What is the goal of Hyperledger Composer?
   for easy integration of blockchain applications with an existing business system.
2. What is the relationship between Hyperledger Fabric and Hyperledger Composer?
   Hyperledger Composer supports Hyperledger Fabric blockchain infrastructure and runtime. It is s built on top of Hyperledger Fabric
3. What do we define within the Model File?
   Assets, participants and transactions. We need to define the model file as part of the Business Network archive
4. What is the relationship between assets, participants and transactions?
   Participants create a transaction to exchange assets.

• What is the goal of Hyperledger Composer?
  Hyperledger Composer is an extensive, open development toolset and framework to make developing blockchain applications easier.
• 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.
• What do we define within the Model File?
  That you can easily and quickly model your current business network.
• What is the relationship between assets, participants and transactions?
  The assets could belong to the participants and the transactions are done by the owners so, they are all placed in one file

1. The primary goal is to accelerate time to value and make it easier to integrate your blockchain applications with the existing business systems. You can use Composer to rapidly develop use cases and deploy a blockchain solution in weeks rather than months. Composer allows you to model your business network and integrate existing systems and data with your blockchain applications.
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 the policy by the designated business network participants.
3. The model file contains your existing assets and the transactions related to them; assets are tangible or intangible goods, services, or property.
4. 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 participants who interact with them.

1. Hyperledger Composer is an extensive and open development toolset that has the purpose to make the development of blockchain applications easier. Indeed, the goal of Hyperledger Compose is to make it easier to integrate your blockchain applications with the existing business systems.

2. Hyperledger Composer supports the existing infrastructure and runtime of Hyperledger Fabric to make it easier to integrate business data system.

3. Assets, participants and transactions.

4. As part of the business network model, participants define the transactions that interact with assets.

3. Assets: participants and transactions
4. Assets: houses and listings
Participants: buyers and homeowners
Transactions: buying or selling houses, and creating and closing listings

1. The goal of Hyperledger Composer is to make it simple and fast for enterprises to develop blockchain application to compliment their already business system
2. Hyperledger Composer sits on top of Hyperledger Fabric
3. Whithin the Model File, we define transactions related to assets within a business
4. The relationship between assets, participants and transactions is their existance on the business network

1. The primary goal is 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 runtime, which supports pluggable blockchain consensus protocols to ensure that transactions are validated according to policy by the designated business network participants.
3. they define the transactionn which can interact with assets, which are tangible and intangible goods, services or property.
4. apart of your business network model, you define transactions which can interact with assets. business networks also include the participants who interact with the assets through transactions.

• What is the goal of Hyperledger Composer?
  This is a simplified abstraction layer sitting on top of HyperLedger Fabric that allows for the easy creation of of organisations, assets, people and the execution of transactions on top of a Ledger Fabric ledger infrastructure so as to quickly model on to the blockchain.

• What is the relationship between Hyperledger Fabric and Hyperledger Composer?
  This is a simplified abstraction of Hyperledger Frabric which integrates with it

• What do we define within the Model File?
  Assets, Participants and Transactions

• What is the relationship between assets, participants and transactions?
  These three are normally grouped together into a Model (.cto) file. Assets will be handled, exchanged etc via transactions which will be initiated by authorised participants within the blockchain. They constitute part of the Business Model Network

1.What is the goal of Hyperledger Composer?
to make developing blockchain applications easier; to accelerate time to value and make it easier to integrate your blockchain applications with the existing business systems
2.What is the relationship between Hyperledger Fabric and Hyperledger Composer?
Fabric provides the infrastructure and Composer runs on top of it
3. What do we define within the Model File?
Business Network Definition: the transactions, assets and participants
4.What is the relationship between assets, participants and transactions?
they are all data comprised in the Business Network Definition

[Bunbo_Hue]

1. What is the goal of Hyperledger Composer?

To make it faster to deploy a blockchain solution for a business in weeks rather than months.

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

Composer exists on top of Fabric. Composer supports the existing Hyperledger Fabric blockchain and makes it simpler to integrate the blockchain.

3. What do we define within the Model File?

Assets, participants and transactions.

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

Assets can be products/properties.

Participants can be the things that interact with the assets, for example buyers and sellers.

Transactions are the event of buying/selling, for example selling a home.
