But is it really that easy to own the majority of nodes ? You don't just need the majority of nodes but the majority of nodes that are voting in any given round and to be eligible to vote in the first place also costs, stake or PoW (I think zerotime is PoW/Pos right ?).
That's what I'm trying to establish. As far as I can tell, there isn't any real cost (neither coins or electricity) to obtaining a majority of nodes, but I'll wait for fusilier's reply.
Are seriously going to analyze a design when you don't even know the data structures? Do you even know how the consensus is formed on chosing the set B, C, D? And many other details he hasn't stated. This is ridiculous.
There are so many aspects that can be hidden in vague specifications.
