How Does the PoS Part of PoA Select the Signing Validators?

The selection process for PoS signing validators in Proof-of-Activity is typically done randomly, weighted by the amount of currency (stake) they have locked up. A user with a larger stake has a proportionally higher chance of being chosen to sign the block.

Once selected, these validators must digitally sign the PoW-generated block template to validate it. A threshold of signatures is usually required to finalize the block.
