Smart contracts replace legal language with computer language to record contract terms, once written, they can be trusted by users, contract terms cannot be changed, hence possessing immutability. The biggest advantage  of smart contracts lies in using program algorithms to replace human arbitration and contract execution, achieving decentralized cooperation and transactions. The technical characteristics of smart contracts include data transparency, inability to tamper with, and perpetual operation, ensuring the fairness, justice, and reliability of the contract."}]}],"pr":"4a41ba0c44a2196edab05ae164b3d325272c96863ce8ed6d13f6e72ceef712ba"}
