I can exploit how NXT works so I will forge more often than I should. I could make 1M NXT forge as often as 2M should.
This is a well-known stake vs computations trade-off. Effective stake asymptotically approaches
200% if burned electricity approaches
infinity.
No, my approach does not require much extra computation.
Could you please point me to some literature on the well-known trade-off? I've read some things about that, but they seemed unpractical. I'd like to know if we're talking about the same thing.
By its very definition activated "Economic clustering" can't open new attack vectors in technical domain. Socioengineering attacks - yes, political attacks - maybe, but technical ones - unbelievable.
Is there a clear definition of how will "Economic clustering" be implemented? if you have a new consensus algorithm, there will be new strengths and new flaws. I'd rather not go into deeper discussion of something that is still not defined.
