IIP-11: Increasing the cost of 51% attack

[midenaio]

Increase the cost of 51% attack by disregarding votes from identities with stake amounts below a certain threshold. This threshold is set as a percentage of the median stake of top 100 accounts.

Why are Suspended and Zombie identities eliminated from the calculation of the median_top100?
This lowers the value since other identities with lower stakes are chosen instead to be in the top 100.

@Zen-44 Suspended and Zombie do not participate in mining so similarly their stakes are not taken into account for median_top100

I like this proposal. It will create a very interesting mix of PoS and PoP regarding the Governance of the network.

Why does it have to be based on stake amount? Coins can be bought, and in theory a few whales can collude to manipulate the network. How about using a combination of other indicators, e.g. Age + Score + Reported flips (within N number of validation ceremonies)? Or perhaps combining both: stake amount threshold + non financial indicators?
