Proof of Stake is the consensus in which validators deposit 32 ETH and are pseudorandomly selected to propose blocks.

Proof of Stake is the consensus in which validators deposit 32 ETH and are pseudorandomly selected to propose blocks.

RANDAO selects the proposer for each 12-second slot. If the selected proposer is offline, the slot stays empty, the proposer takes a small inactivity penalty and the network continues. Attestation committees vote on block validity, and finality needs more than two thirds of them, a guarantee that the longest chain of PoW, being only probabilistic, cannot give.
