Firstly, the consensus mechanism ensures the consistency  and integrity of data in the blockchain network. Through a series of algorithms and protocols, the consensus mechanism enables nodes in the network to reach a consensus on the content of blocks, thereby ensuring the accuracy and reliability of the blockchain ledger. This helps prevent hackers from tampering with blockchain data, thereby safeguarding network security.↵↵Secondly, the consensus mechanism helps prevent fraudulent behaviors such as double spending. In the blockchain network, the consensus mechanism ensures the consistency of transaction order, thereby avoiding the occurrence of the same transaction being conducted multiple times in the network. For example, when a user attempts to transfer the same amount of currency to multiple recipients, the consensus mechanism can prevent such fraudulent behavior from taking place."}]}],"pr":"e8f7c26baa6d38d5042cfc58caf748d2adc17c1d80de7befe1f23c591bb65e40"}
