Separation of security token from operational token

Transaction Pruning

* Since NEM is not fully open source the exact inner working of POI is unknown

** Ethereum plans to switch to POS sometime in the future but there is no concrete time line for this

*** Assets and trading on top of Bitcoin are implemented using other protocols like OMNI and Counter Party

**** In theory, Ethereum smart contracts can mimic this unique NXT and Ardor functionality but developing such smart contract using the limited tools provided by Ethereum would be very difficult

***** plasma.io paper was released recently, perhaps in response to Ardor, but actual implementation is years away
