Ark Delegate system, DPoS, Questioned by Vitalik

http://vitalik.ca/general/2017/12/17/voting.html

A technical run down on Blockchain governance. Vitalik gives a detailed rundown on various blockchain goverance methods used today. EOS, NEO, LSK, TEZOS, ARK.

He critiques Ark under the section 'Game-theoretic attacks', then goes onto to state;

'It’s worth noting that this section is not a prediction that all tightly coupled voting systems will quickly succumb to bribe attacks. It’s entirely possible that many will survive for one simple reason: all of these projects have founders or foundations with large premines, and these act as large centralized actors that are interested in their platforms’ success that are not vulnerable to bribes, and hold enough coins to outweigh most bribe attacks. However, this kind of centralized trust model, while arguably useful in some contexts in a project’s early stages, is clearly one that is not sustainable in the long term.'

Have a read come back and chat, I'd love to know why its not a sustainable model. I think utilising ARK's side chains could slove some of the issues Vitalik has.
