| #### When do validators opt in? |
There was a problem hiding this comment.
To implement top-n, we should just have an automatic process every block or epoch or whatever, which automatically opts in validators in the top-n, just as if they had sent the message themselves.
|
|
||
| `top_N` can be up to 95% to capture the current case of Replicated Security where we allow the bottom 5% of validators to opt out. There is no reason for `top_N` to be higher than 95%. Smaller chains that belong in the bottom 5% validators can choose to opt in if they want to validate. | ||

| So, the fields can take the following values: |

This might change, not a huge deal. We may want to change how much we limit the number of top n options that are available, but that can be a very surface level thing here in the prop

| Note that in a Top N consumer chain, the top `N%` provider validators have to validate the consumer chain. | ||
| Nevertheless, validators in the bottom `(100 - N)%` can opt in to validate as well. | ||
| Provider validators that belong to the top `N%` validators are immediately opted in to validate a Top N consumer chain. | ||
| This means that if a validator `V` belongs to the top `N%` validators but later falls (e.g., due to undelegations) to the bottom `(100 - N)%`, `V` would still be considered opted in and has to validate unless `V` sends a `MsgOptOut` message (see below). |

So you would have to opt out again every time you get in the top N, right?
i.e.
val V is in top N
falls below top N
opts out
gets back in top N
falls below again
has to opt out again
not really a problem, because this is already annoying and validators that skirt in and out of top N probably also don't really want to turn on/off their nodes all the time, so they'd probably just stay opted in until they are for sure not in the top N anymore, but maybe something to remember to communicate properly
