The source code of a smart contract contains the specific logic and business rules of the contract, which determine its behavior on the blockchain. Although some blockchain platforms (such as Ethereum) provide graphical interface tools for writing smart contracts, allowing users to create contracts without writing source code, mastering source code writing is still a basic requirement for smart contract  developers. Because once the contract is deployed on the blockchain, its source code cannot be modified, so writing clear and reliable source code is essential to ensure the contract's security and functionality."}]}],"pr":"b4bc9a08c5da09fff3b3c1ccfa253dd45994843f5cc4028ca9e843bd7857369d"}
