We do not talk about Mesh security anywhere else so I think we can remove.

This is a security measure that makes it harder for a single large validator to take over a consumer chain:
It mitigates the risk of an Opt In chain with only a few validators being dominated by a validator with a large amount of stake.
For example, setting this fraction to 33% would mean that no single validator can have more than 33% of the total voting power on the consumer, and thus no single validator would be able to stop the consumer by going offline.
The consumer chain can specify a _power cap_ which corresponds to the maximum power (percentage-wise) a validator can have on the consumer chain.
