Really simple models

Quick reusable POCs

Rather than weeks, think hours to develop production-ready applications that go from the web-browser all the way back to the blockchain.

Data integration

From enterprise systems of record to best of breed dev ops: Composer uses LoopBack to connect your blockchain to your existing systems.
