Method for executing smart contract, blockchain node, and storage medium

A blockchain node for executing a smart contract, comprising:

• one or more processors;
• and
• one or more computer-readable memories coupled to the one or more processors and having executable instructions stored thereon that are executable by the one or more processors to perform acts including:
• starting, after a smart contract of bytecodes has been deployed in a blochchain network, to compile a bytecode of the bytecodes of the smart contract into a machine code by using ahead of time (AoT) compilation and to store the machine code;
• in execution of the smart contract, executing the machine code of the smart contract in response to the machine code being locally stored;
• and
• in response to a machine code of the smart, contract not. being locally stored. interpreting and executing, by the blockchain node in executing the smart contract, a bytecode of the bytecodes of the smart contract,
• wherein the interpreting and executing the bytecode of the smart contract includes:
• querying, by the blockchain node in executing the smart contract, a current AoT complication status of the bytecode of the smart contract;
• in response to the bytecode being in AoT compilation, interpreting and executing the bytecode of the smart contract;
• and
• in response to the bytecode not being in AoT compilation, starting AoT compilation to interpret and execute the bytecode of the smart contract.

A non-transitory storage medium, the storage medium having executable instructions stored thereon that are executable by one or more processors to perform acts including:

• starting, after a smart contract of bytecodes has been deployed in a blochchain network, to compile a bytecode of the bytecodes of the smart contract into a machine code by using ahead of time (AoT) compilation and to store the machine code;
• and
• in execution of the smart contract, executing the machine code of the smart contract in response to the machine code being locally stored;
• and
• in response to a machine code of the smart contract not being locally stored, interpreting and executing, by the blockchain node in executing the smart contract, a bytecode of the bytecodes of the smart contract,
• wherein the interpreting and executing the bytecode of the smart contract includes:
• querying, by the blockchain node in exciting the smart contract a current AoT compilation status of the bytecode of the smart contract:
• in response to the bytecode being in AoT compilation interpreting and executing the bytecode of the smart contract;
• and
• in response to the bytecode not being in AoT compilation, starting AoT compilation to interpret and execute the bytecode of the smart contract.
