Validator nodes are responsible for validating and packaging transactions to ensure that they comply with the rules specified by the blockchain and to ensure that the order and records of all transactions  in the blockchain network are correct. Under the proof of stake (PoS) consensus mechanism, the validator set is also responsible for electing the generator of new blocks, thereby maintaining the security and stability of the entire blockchain network. In addition, validator nodes also confirm transactions in the blockchain network, ensuring that transactions are accurately recorded in blocks, and thus ensuring the consistency of the blockchain."}]}],"pr":"f92ebe2b0b221e1039cf2604d44e06a353af5494ea4ffe22d538f0e48c7af841"}
