I think a better method would be to globally limit amount of forging power as a variable figure based on the target of the current block or that and some other factors. This would allow us to optimally maximize the use of forging power while protecting the network from letting 1 group, either pooled or a single account, get too large for any network target condition at any particular time. It should work on a first come first served basis such that only the first group of users declared in the blockchain as having their forging power in the leased pool to have their funds used in the pool, and that other users beyond that amount defined by current target would temporarily have their entire balances not part of the pool's forging power if the target is too high, and when target lowers enough, they get put back in.
I believe this should all be possible to be validated on the blockchain by the entire network.
This method would put the onus of responsibility for maximization of pooled forging power on the ACCOUNT OWNERS. They would have to think about which pool is best for their particular balance if they wanted maximization.
Now Im not quite sure I really understand forging, or target, etc. If I did then I would complete the white paper. But my point would be that at 100% target, then almos all NXT is forging, right? at 400% then only 1/4 of all NXT is forging, right? If thats the case then my idea for limiting forging is to prevent someone from taking control of the network.
But I could be way off here. Can someone correct me if Im wrong? (I still dont quite understand what it means when target is under 100% because its just impossible for 150% of all NXT to be forging. So I kind of think then a target of 50% mean that maybe 100% of all NXT was forging but the block came 30 secs after the previous block, or maybe 50% of all NXT was forging, and the block came after only 15 secs of the previous block? Is that about right?
Like I said, my idea up there could be completely unfeasable; but it would be good I think to have the network to simply not allow some large pool to take over. Can someone smarter than me tell me if Im out in the weeds?
