As I know, Ethereum Casper PoS implementation randomly selects 250 validators from the validator poll for an epoch. What is the random algorithm for this selection?

I am not sure about casper but POS algortihms in general use two common methods which are Randomised Block Selection and Coin Age Selection.
In the first, validators are selected based on a combination of the lowest hash value and highest stakes. Whereas, in the Coin Age method, validators are chosen based on how long their tokens have been staked for.

Coin age does sound super deterministic to be. What is random about it? Do staked coins get "kicked out" at some point? Apr 30, 2021 at 14:47
