This is because the data blocks in the blockchain system are generated in sequence according to the time  order, and each block contains the hash value of the previous block, forming a chain structure. Therefore, in the blockchain system, new blocks need to be generated and added to the chain within a certain period of time to maintain the continuity and security of the chain.↵↵At the same time, the upgrade of blockchain is also influenced by factors such as network consensus algorithm, cryptographic technology, and smart contracts. These technologies are constantly verified and updated in the operation of the blockchain system to ensure the security and consistency of the data. Therefore, in actual operation, the upgrade of blockchain needs to meet certain requirements."}]}],"pr":"76e8608a922cfd578fe650ce0ea18411a79e7b4747bea84e55b03712339d3784"}
