Hyperledger Composer

Bitcoin Cash Definition

DEFINITION of Hyperledger Composer

Hyperledger Composer is a set of tools that allow various business owners, operators and developers to create blockchain applications and smart contracts aimed at solving business problems and / or improving operational efficiency. (For more information, see Understanding Smart Contracts.)

DISTRIBUTE Hyperledger Composer

Hyperledger Composer is built in Javascript, a platform-independent programming language that also supports the use of built-in libraries and uses the available functions and scripts to make utilities more scalable and reusable.

Hyperledger Composer allows executives to collaborate with developers

Using Hyperledger Composer, a businessman without technical knowledge can easily collaborate with a developer to create specific functionality. They include the definition of business rules on the basis of which blockchain transactions will be processed, the definition of assets traded in blockchain-based use cases and the definition of controls for participants, their identities, roles and levels of to carry out the different types of transactions.

Likewise, a developer using Hyperledger Composer can easily create and configure the main blockchain components that include network digital assets, transaction logic, participants and access controls. Composer supports the sharing, reusability and scalability of components between various organizations. You can easily generate the scripts and APIs necessary for implementing the business using Hyperledger Composer. It also supports use cases and real-time testing, which can even be done via the Web Composer playground without the need for local installations.

By using Hyperledger Composer, it is possible for an individual to create and execute a sample blockchain and to grant restricted permissions to various participants. For example, one can easily create a “perishable product network” that facilitates the trade of items like fruits and vegetables, include participants such as farmers, shippers and importers, define individual roles for each participant, define and execute the terms of the agreement between participants, track shipments, recognize, monitor and report the status of goods at various stages of the supply chain and payment management.

Hyperledger Composer offers many advantages, including faster creation of blockchain applications in easy steps, fluid and inexpensive modeling and testing allowing the user to create, test and deploy various options, then to implement the one that offers the best fit, and reusability of existing applications and APIs that reduce efforts and costs.

The corporate network archives are at the heart of the Hyperledger Composer architecture and they store the basic data and functionality of the corporate network which includes the business model, transaction logic and controls. access. Composer Playground is the web interface for modeling business requirements and functions, functional testing, as well as deployment testing on a live blockchain. A LoopBack connector that supports various APIs and integration capabilities allows a variety of client applications as well as non-blockchain applications an easy way to interface with Hyperledger Composer.

Hyperledger Composer is one of many Hyperledger projects hosted by The Linux Foundation. (See also, Definition of Hyperledger fabric.)
