Hyperledger Composer is one of the many offerings from the Hyperledger Project as developers continue to expand its areas of influence.
As an open development framework and toolset to simplify the development of blockchain, Hyperledger Composer is of interest to anyone working in the industry.
The mission of Composer is to more easily integrate blockchain applications with existing business systems. Composer can be employed to rapidly develop use cases and then deploy a blockchain solution in a matter of weeks instead of months.
Like other projects, Hyperledger Composer supports both the current Hyperledger Fabric blockchain infrastructure and runtime, and these support pluggable blockchain consensus protocols that guarantee transactions are validated as per policy only by selected business network participants. In addition, it’s possible for everyday applications to use the data from business networks, which means users will be provided with controlled access points.
Hyperledger Composer works in a myriad of ways, but one example is that of a business network which can be modeled as follows:
In such a network, participants can have access to transactions restricted based on their role as a buyer, seller or realtor. It’s then simple for the realtor to create an application and present buyers and sellers with a user interface through which they can view open listings and make an offer. In the event that a business already has an inventory system in place, this network can be integrated and new houses added as assets while sold properties are removed.
There are many different business network models that are compatible with Hyperledger Composer, and the developers are working to add increased functionality on an ongoing basis.
