Firstly, smart contracts encapsulate predefined  states and transition rules, scenarios for triggering contract execution (such as reaching a specific time or occurring specific events), and corresponding actions under specific scenarios. Then, when external events satisfy triggering conditions, monitoring servers send transactions (transactions) to smart contracts. Next, after receiving the transaction, smart contracts perform secondary verification to confirm the authenticity of the event. Finally, after satisfying all conditions, smart contracts execute corresponding operations according to pre-defined rules."}]}],"pr":"d5de6109314d1297da1d4a0cfc98da0404e30be8a115bc19aad5a0e85c2e933c"}
