In this case even WHO matters. Filtering new nodes through a master node as is happening in this chain, give super power to a specific node over the society.
The idea of offline mining is brilliant, yet very hard to apply. This project did a promising job so far, but there is some concern about its security and generality. If one day, whoever has access the golden gate (the master node) decides to not accept new nodes or transactions from a specific country or IP range, he/she could simply block the incoming data and society cannot do any thing for that. Society even will not know about that because VFC miners and holder must see network through the master node's eyes.
