The execution process of smart contracts involves multiple nodes, and each node needs to verify the results of the contract execution. Only when the majority of nodes reach a consensus can the contract be executed. This effectively prevents malicious tampering and attacks, ensuring the security of smart contracts."}]}],"pr":"b3e2474f54958e819bcf64a034b81c54b3ce201c49546de70ca2e5396ce111c7"}
