The working principle of smart contracts is based on the mechanism of transaction processing and storage, as well as a complete state machine. Transactions mainly contain data that needs to be sent, while events describe the information of these data. When transactions and event information are input into smart contracts, the resource status in the contract resource collection is updated,  triggering the state machine judgment of the smart contract. If the trigger conditions of one or more actions in the automatic state machine are met, the smart contract will automatically execute the contract actions according to the preset information."}]}],"pr":"e873f75ac180b26ea200a948b2330ff851a3b9bcb266488c1e14ba3c981a35fe"}
