Firstly, blockchain adopts a decentralized network structure, which ensures that validators have equal status and balance each other. Secondly, consensus rules require validators to complete signatures within a certain time frame, otherwise they will face penalties, which helps ensure the timeliness of validators. In addition, blockchain also adopts consensus algorithms such as Proof of Work or Proof of Stake, which require validators to exert certain efforts or possess corresponding stakes, thereby increasing the cost of malicious activities. Meanwhile, the immutability  of data in blockchain also ensures that"}]}]}
