Hyperledger Composer (previously Fabric Composer) provides a layer of abstraction on top of the Hyperledger Fabric blockchain for building business applications. Please use this tag for questions relating to the use of Hyperledger Composer, but not general Hyperledger Fabric questions. Defects in Hyperledger Composer should be reported as GitHub issues.
Hyperledger Composer provides a layer of abstraction on top of the Hyperledger Fabric blockchain. Developers can design in terms of business networks, participants, identity, assets, registries, transactions, events and links, in contrast to the low level abstractions of chaincode and key-value stores.
The composer modelling language makes it easy for developers to model the specific nature of their business domains. The interactive web Playground allows them to author and test these models, and then create domain specific APIs for developers building applications.
Developers can use Composer tools to create applications which exploit these APIs, and create loopback connectors which provide connectivity between the blockchain and their existing systems.
We're keen to build a community so please take a look!
