Hyperledger Composer Basics - Reading Assignment

  1. Create an efficient means to link existing business data systems to blockchain applications.
  2. Hyperledger composer supports the existing Hyperledger Fabric blockchain infrastructure.
  3. Assets, participants and transactions
  4. As part of your business model you can define the transactions that interact with the assets- then include the participants who interact with them having the option to assign a unique identity to each participant

1.Composer was intended to make it easier to create blockchain applications.

2.Composer is a tool-set built on top of Hyperledger fabric.

  1. The Model File defines the elements being included in the application. The Business Network Definition. In the example this included assets, transactions and participants.

  2. These aspects are defined by the script file, transaction file and query file.

1. What is the goal of Hyperledger Composer?
Our primary goal is 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?
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. What do we define within the Model File?
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.

  1. Hyperledger Composer allows you to model your business network and integrate existing systems and data with your blockchain applications. This is a toolset to set up your blockchain-based infrastructure.
  2. In composer the transacting assets are defined and your business is modelled so that it can record data on the hyperledger fabric blockchain. Composer is the business modeler, fabric is the blockchain (database).
  3. A file that describes the types of assets, participants and transactions that will be recorded on the blockchain.
  4. An asset is a good that can be aquired or sold by participants. Participants are individuals interacting with your business. Transactions are the operations between assets and participants.

  1. What is the goal of Hyper-ledger Composer?
    To make it easier and faster to link existing business data systems to block-chain applications.
  2. What is the relationship between Hyper-ledger Fabric and Hyper-ledger Composer?
    Hyper-ledger Composer has been designed to make it easier to integrate existing business data systems to the Hyper-ledger Fabric block-chain.
  3. What do we define within the Model File?
    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 block-chain.
  4. What is the relationship between assets, participants and transactions?
    Assets will have transactions related to them. Participants are those authorized to interact with the data regarding assets and transactions.

  1. Hyperledger Composer was designed to be a more ‘off the shelf’ program, an out-of-the-box template type solution, to ease initial design difficulties at the outset of designing the needs of projects, particularly with regard to integrating blockchain solutions with legacy systems, with everything under one roof.

  2. Hyperledger Composer is an application that runs on top of Fabric, which itself runs on Hyperledger.

  3. The Model File contains the ‘Assets’, the ‘Participants’, and the ‘Transactions’.

  4. ‘Participants’ can be created with IDs of various types and permissions, and, depending on what permissions those IDs have, they can interact in various ways with ‘Assets’ via ‘Transactions’.
