Thanks for the clarifying comment. You can also use the native blockchain currency, which is disabled by default but can be reactivated using the blockchain parameters:

For example you can set just the first-block-reward parameter to a non-zero value, in which case the node that creates the chain (and its first block) will start with all the native currency, and no other block validators will earn any of that currency. The native currency can then be sent between nodes.
