- Even though it seems to be good for the network to have a small number of validators with high thresholds (c.f. 2017-12-21 notes), this is not a stable population configuration.
- Any population with a small variance in the thresholds will likely be inefficient and the higher the mean threshold the less efficient it will be. However, since high threshold invaders are successful, this seems to indicate that economic pressures are towards inefficient consensus. This provides further evidence that additional constraints in the protocol need to be in place, such as the decay of REV earned by validators proposed by Greg (though the details of this have yet to be worked out).
