I was more concerned about the case where someone is specifically trolling or trying to load up all slots with their own nodes.
If that actor doesn’t then actually run the nodes there’s 0 chance that new good nodes are added.
So: the randomization case does have the factor that wealthier individuals can add more nodes there is some chance that others are selected.
I’m not actually sure which is worse. Are there other options for the short term?
Edit: NOTE Auctions also have the effect that richer individuals or consortiums can more easily get node slots because they can absorb the opportunity cost of the initial stake more easily. There are some approaches to getting around this such as NEAR’s approach where all stakers are divided into tranches and the winners of the auction are selected such that certain % of the total stake comes from stakers bidding in the range of those tranches.
I think approaches like that do need a little work from the auction theory perspective to tell us about the properties we will care about here.
