Firstly, the consensus mechanism ensures the data consistency in the blockchain network, only transactions that have been verified through consensus can be added to the blockchain, thus avoiding data tampering and forgery. Secondly, the consensus mechanism uses encryption technology (such as Hash algorithm, encryption algorithm, digital signature, etc.) to ensure the confidentiality, integrity, and authenticity of the data. In addition, the consensus mechanism also adopts different types of consensus algorithms, such as proof of work and proof of stake, to balance the relationship between security and efficiency.\n\nIn the proof of work mechanism, nodes need to solve complex mathematical problems to generate a specific number of blocks within a certain period of time. The difficulty of the problem increases as the number of blocks increases, which ensures the security of the blockchain network.  Meanwhile, the proof of stake mechanism selects the next block producer based on the stake of the node, which encourages nodes to"}]}],"pr":"32403d0ee5d36e95b24627d9b11b4f3ca421d3c12138c8e62f2cb8d431799b29"}
