Due to the decentralized design of blockchain, the propagation of data in the network needs to undergo multiple node verifications. A larger propagation delay means that attackers need to spend more time cracking or tampering with the data in the blockchain. Additionally, propagation delay can enhance the resistance to attacks of blockchain systems, as attackers need to break into a large number of nodes in a short period of time to achieve their goal of tampering with data. In summary, the propagation delay parameter contributes to improving the security of blockchain systems to a certain extent."}]}],"pr":"64fafa9469dfb09ff833696ae87604a1cd5928999de682ada082837e3cdc25ba"}
