Every chain must have a unique identifier or
chain-id. Tendermint requires each application to define its own

- Identifier: Unstructured string that defines the name of the application.
- Version Number: Is the version number (always positive) that the chain is currently running. This number MUST be incremented every time the chain is upgraded or forked in order to avoid network or consensus errors.
