An attestation is the vote by which a member of a proof-of-stake committee confirms that it has seen and validated the proposed block. In PoS, a random subset of validators is selected as the attestation committee for each slot, and the block becomes canonical when it receives more than two thirds of the committee's votes.

Not every validator attests to every block: committees rotate to distribute the workload.
