A smart contract is an automatically executed contract that converts contract terms and conditions into computer code (script) and deploys it on the  blockchain. Each transaction and contract execution must take place within the blockchain. Smart contracts have characteristics such as decentralization, tamper-proof, and full traceability, ensuring the reliability and security of contract execution. Through smart contracts, parties can achieve automatic contract execution and trust transmission without the intervention of a third party."}]}],"pr":"34530294da490039c37e2d4f460cefb0dacfc8a6afb4b4135364817af16ca199"}
