How Does the PoA Model Address the Potential Centralization of Mining Pools in PoW?
PoA addresses PoW centralization by shifting the final block validation and reward distribution power to the PoS stakers. While mining pools can still centralize the PoW block creation, their power is limited because they cannot unilaterally validate the block or censor transactions without the cooperation of the PoS majority.
This separation of block creation and validation decentralizes the ultimate control.
