How Does the Staker Selection Process in PoA Enhance Security?

The staker selection process in PoA is designed to be random or pseudo-random. This prevents miners from knowing in advance which stakers will be validating their block, making collusion much more difficult.

Random selection ensures a diverse and unpredictable group of validators, which is a key defense against a coordinated attack, thereby enhancing the overall security of the PoS phase.
