But where does "off Hive blockchain" fit in?

An example is The Food Game #PEPTEvent where you convert food gold to #ePay tokens.

Also, the ePayTraffic reward system is being configured as a way to mine ePay tokens. In the trading system you have the option to convert earned rewards to a Paypal payment and I will be adding code to allow converting to ePay tokens. When you fund your trading account it can be used to buy #PEPT tokens. Use to be called Project Units. Still some manual entry for me but another opportunity for process improvement.
