Every NXTer can forge, we all are forges, there is no "part" here. And if there is no forger, then there is no confirmed transaction.
I was talking about treating pure forging like a busniess. Goal: highest fees. But, for example, merchants (or just senders) a part of Nxters too (will be in worst case). Goal: lowest fees to compete. Not only different goals, opposite goals. How to reach equilibrium? How to reach win-win situation? I think: not but supressing losers of voting, but in competent discussion (public or not) and trying of models (in worst case in different chains/projects). Infinite evolving, much thinking required.
Oh, it does matter, because we cannot have a proof that they are really 1 million.
We don't need exact numbers, we need close assumption. Do u think competence on every problem distributed exactly like wealth? I don't think so.
