Pre-transactions refer to the preliminary transactions that participants need to conduct before executing specific protocols. These transactions are usually used to establish trust and protect the interests of both parties during the execution of the agreement.\n\nFor example, in the Internet of Vehicles scenario, traffic entities need to undergo identity authentication to ensure the security of data interaction. In this process, parties can establish trust relationships through pre-transactions, such as verifying the identity of vehicles and the qualifications of drivers. These pre-transactions are recorded and verified in the blockchain network to ensure the security of data interaction."}]}],"pr":"ff0f3d204efc88d7d7ef1cd74751286e1ccf454ff3dae0345fd2e20aa2ea1397"}
