Katelyn Baker c93b0284ef CORDA-593 - Strip web front end from the SIMM demo (#1574) 
* CORDA-593 - Strip web front end from simm-demo

Also, pre cutting V1 remove the documentation references to SIMM, the
plan being once V1 is cut we can spend a little time thinking about how
we want to prevent the SIMM back end as a useful, teachable, demo

* CORDA-593

What is a CorDapp?

Corda is a platform. Its functionality is extended by developers through the writing of Corda distributed applications (CorDapps). CorDapps are installed at the level of the individual node, rather than on the network itself.

Each CorDapp allows a node to handle new business processes, for example asset trading (see irs-demo). It does so by defining new flows on the node that, once started by the node owner, conduct the process of negotiating a specific ledger update with other nodes on the network. The node's owner can then start these flows as required, either through remote procedure calls (RPC) or HTTP requests that leverage the RPC interface.

CorDapp developers will usually define not only these flows, but also any states and contracts that these flows use. They will also have to define any web APIs that will run on the node's standalone web server, any static web content, and any new services that they want their CorDapp to offer.

CorDapps are made up of definitions for the following components:

  • States
  • Contracts
  • Flows
  • Web APIs and static web content
  • Services
