What is Hyperledger Composer?
Hyperledger Composer is a framework that facilitates the development of blockchain applications. Hyperledger Composer is a collection of open-source tools that enables company owners, operators, and developers to construct blockchain applications and smart contracts to address business challenges and enhance operational efficiencies. This is an instance of a commercial implementation of blockchain-as-a-service (BaaS). Hyperledger Composer is a project under the Hyperledger initiative, sponsored by the Linux Foundation in partnership with corporate members.
As of August 2019, the Hyperledger Composer project has been marked as deprecated. This indicates that although it is still being used, none of the maintainers are actively working on adding new features or providing support. The composer tool has been included in Hyperledger Fabric version 1.4 and above.
Comprehending the intricacies of Hyperledger Composer
The developers of Hyperledger Composer use Javascript, a platform-agnostic programming language that enables them to utilize built-in libraries, functions, and scripts to enhance the scalability and reusability of utilities. Composer is a framework for developing apps that makes creating Hyperledger Fabric blockchain applications easier and faster.
Hyperledger Composer enables seamless collaboration between a non-technical business individual and a developer to construct tailored functionalities. The tasks involve establishing the business rules that govern the processing of blockchain transactions, specifying the assets involved in blockchain-based scenarios, and establishing controls for participants, including their identities, responsibilities, and access privileges for carrying out different types of transactions.
Similarly, a developer utilizing Hyperledger Composer may effortlessly construct and customize fundamental elements of the blockchain, such as the network’s digital assets, transaction logic, participants, and access restrictions. Composer facilitates components’ sharing, reusability, and scalability among different companies. Hyperledger Composer enables the effortless generation of essential scripts and APIs for seamless business deployment. Additionally, the web-based Composer playground facilitates the execution of use cases and real-time testing, eliminating local installment requirements.
With Hyperledger Composer, individuals may develop and execute a prototype blockchain and provide limited access to different participants. For example, it is possible to construct a “Perishable Goods Network” that streamlines the exchange of products such as fruits and vegetables. This network would involve various participants, such as farmers, shippers, and importers. Participants will have specific responsibilities, and we will establish and enforce unambiguous agreement terms. The network would also enable the tracking of shipments, the acknowledgment and monitoring of goods at different stages of the supply chain, and the management of payments.
Unique Factors to Consider
Hyperledger Composer provides numerous benefits, such as expedited development of blockchain applications through a simplified process, efficient and cost-effective modeling and testing capabilities, enabling users to construct, evaluate, and deploy multiple options and select the most suitable one, and the ability to reuse existing applications and APIs, resulting in reduced effort and expenses.
The Business Network Archive is a crucial component of Hyperledger Composer’s architecture. It is responsible for storing and managing the fundamental data and features of the business network, such as the business model, transaction logic, and access restrictions. The Composer Playground is a web-based interface that allows for modeling business requirements and functionalities, functional testing, and deployment testing on a live blockchain. A LoopBack connector with versatile API support and integration features provides a convenient means for client and non-blockchain applications to communicate with the Hyperledger Composer.
Conclusion
- This Composer team designed a collection of tools for constructing corporate blockchain applications that focus on business needs. The Hyperledger project operates it.
- The developers designed Composer to streamline open-source blockchain application development that promotes cooperation among enterprises and commercial networks.
- The summer of 2019 suspended the composer’s development, and the more extensive Hyperledger Fabric platform has now integrated it.
