A smart contract is an automated program that runs without the control of any centralized institution, relying on the consensus mechanism of the blockchain network. Contract migration messages enable smart contracts to be migrated between different blockchain platforms, thus achieving cross-platform cooperation and execution. In addition, contract migration messages can also be used to update and optimize the code of smart contracts, improving the efficiency and security of contract execution, and ensuring the smooth  progress of transactions in blockchain networks."}]}],"pr":"0a0b9b16483bd3f64d6fecd28c1eec34dcda3d64a0e289da880753555456aa07"}
