Smart contracts are automated contracts based on blockchain technology that can automatically execute contract terms and transmit value between parties. They are deployed on the blockchain through smart contract platforms, ensuring the immutability and transparency of contract content, as all transactions  are recorded on the blockchain. This means that anyone can view the transaction history, and once recorded on the blockchain, transaction records will never be changed. Additionally, the execution of smart contracts is automated, meaning that when certain conditions are met, the contract will automatically execute, thereby reducing errors and fraud."}]}],"pr":"314b9ff2f227341eb7f3b87feeac0d2568e244d9f3746354723b8d020addff64"}
