cordapp demonstrating central bank to facilitate currency issuance, transfer to consumers and transfer within consumers, and consumers destroying their cash

The Central Bank CorDapp

This CorDapp comprises a demo of cash that can be issued, transferred and destroyed (aka removed from circulation). The CorDapp includes:

• An cash state definition that records an amount of any currency with bank, and owner parties. The cash state
• A contract that facilitates the verification of issuance, transfer (from one owner to another) and removing of cash.
• Three sets of flows for issuing, transferring and destroying cashs.
• It also includes test cases for contract testing

The CorDapp allows you to issue, transfer (from old owner to new owner- this could be from bank to owner too) and remove cash. It does not currently have an API yet (in works).
