Smart contracts are an application based on blockchain technology, which features decentralization, trustlessness, autonomy, and tamper-proof characteristics. Once a smart contract is deployed on the blockchain, its code  and execution results will be protected by the blockchain network, ensuring the accuracy and credibility of contract execution.\n\nHowever, although the execution of smart contracts cannot be tampered with, the contents of smart contracts themselves can be upgraded. A common approach to upgrading is to create a new smart contract that includes updated features and logic, while retaining the data and historical records of the old contract."}]}],"pr":"03b41cbf44880e021c3b4854e146d390a1f47b17d0c4d3ffa0e9e181a659b73f"}
