Attestation

A validation mechanism in blockchain networks that employ a Proof-of-Stake consensus mechanism, where a selected validator node proposes a block and other validators (i.e., attesters) vote to confirm its correctness. The network reaches consensus when a block receives a threshold of attestations, with the weight of these votes proportional to the amount of cryptocurrency staked by the validators. This process helps maintain network synchronization and determines which chain the network recognizes as valid.
