How Are Validators Selected in the Proof-of-Stake Phase of Proof-of-Activity?

In the Proof-of-Stake phase of Proof-of-Activity, validators are typically selected randomly from the pool of active stakers. The probability of being chosen is often proportional to the number of coins a user has staked.

This means that the more coins a user holds and stakes, the higher their chances of being selected as a validator. This random selection process is crucial for the security of the network, as it makes it difficult for any single entity to predict or control who will be chosen to validate a block.
