Hyperledger Composer is a powerful set of open-source tools designed to allow businesses, operators, and developers to create streamlined blockchain applications and smart contracts. By offering solutions for solving business challenges and improving operational efficiencies, Hyperledger Composer stands out as a definitive example of Blockchain-as-a-Service (BaaS). Initially launched as an independent project under the Linux Foundation, Hyperledger Composer has worked in collaboration with prominent corporate members of the Hyperledger community.
As of August 2019, the Hyperledger Composer project is in deprecated status. While it remains in use, no new features or support are being developed as it has been integrated into Hyperledger Fabric v1.4+.
Empowering Features of Hyperledger Composer
- Hyperledger Composer is one of the primary tools under the Hyperledger project, providing a beginner-friendly environment to create enterprise-grade blockchain solutions.
- It fosters collaborative blockchain application development, facilitating seamless integration between various business entities and their respective networks.
- Despite its deprecation in 2019, the functionalities have been absorbed into the more comprehensive and scalable Hyperledger Fabric platform.
Unlocking the Potential of Hyperledger Composer
Hyperledger Composer simplifies the development of blockchain applications using JavaScript, a flexible and widespread programming language. It vastly enhances an application’s scalability, reusability, and re-engineering capabilities. Here’s why Hyperledger Composer has been a game-changer for blockchain developers and business professionals alike:
User-Friendly Development Environment
Hyperledger Composer’s components, built on JavaScript, provide a consistent and reliable development experience. The platform unifies programming frameworks, built-in libraries, and utilities, making the designing and coding process effective and efficient.
Non-technical business stakeholders can easily collaborate with developers to customize specific features. Key business rules like blockchain transaction processing, asset management, and participant controls based on identities and roles can be visually and interactively defined, minimizing technical barriers in blockchain deployments.
Dynamic Developer Tools
Developers leveraging Hyperledger Composer can configure critical blockchain components, which include digital assets, transaction logic, participant management, and access controls. It ensures sharability, reusability, and scalability across various organizational ecosystems. By generating essential scripts and APIs, Hyperledger Composer supports diverse enterprise needs through modular components tested in real-time using the Composer Playground.
Realizing Practical Blockchain Applications
Consider creating a “Perishable Goods Network” using Hyperledger Composer. In mere steps, developers can:
- Allow participants like farmers, shippers, and importers to join the network.
- Assign roles and permissions to ensure successful collaboration and resource sharing.
- Define and monitor rules for asset exchanges like fruits and vegetables within the blockchain network.
- Track shipments and ensure goods are maintained and reported accurately across the supply chain, providing economies of environmental and cost-saving solutions.
Insights and Special Considerations
Assurance, versatility, and cost-effective modeling of blockchain applications make Hyperledger Composer an invaluable tool for businesses. Key components contributing to this include:
Business Network Archives
Central to Composer’s setup, the Business Network Archive encapsulates core business data and functionalities like network models, transaction logic, and access controls within bundled archives easily deployable on actual blockchains.
Composer Playground
The platform provides a savvy, web-based interface to model business rules, run functional tests and witness live blockchain deployment performances, ensuring thorough operational insights.
Integration Capabilities
A LoopBack connector facilitates API integration, interfacing various client applications—including non-blockchain systems—with the Composer environment, ensuring easy adoption across techstack borders.
In conclusion, even though Hyperledger Composer has ceased active development, its merger with Hyperledger Fabric signifies its lasting legacy, offering powerful insights and solutions to streamline and innovate blockchain applications.
