Normally, you'd interact with a CorDapp via a client or webserver. So we can focus on our CorDapp, we'll be running it via the node shell instead.

Once you've finished the CorDapp's code, run it with the following steps:

• Build a test network of nodes by opening a terminal window at the root of your project and running the following command:

  • Windows: gradlew.bat deployNodes
  • macOS: ./gradlew deployNodes

• Start the nodes by running the following command:

  • Windows: build\nodes\runnodes.bat
  • macOS: build/nodes/runnodes
  • linux: ./deploy.sh

States define shared facts on the ledger. Our state, CbioState, will define a CBIO. It will have the following structure:

-------------------
|                 |
|   CbioState     |
|                 |
|   - owner       |
|   - amount      |
|   - paidValue   |
|   - lastOwner   |
-------------------

Contracts govern how states evolve over time. Our contract, CbioContract, will define how CbioStates evolve.
