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

A blockchain node for executing a smart contract, comprising:

• a processor;
• and
• a memory coupled to the processor and having executable instructions stored thereon that are executable by the processor to perform acts including:
• starting, by a blockchain node of a blockchain network after a smart contract of bytecodes has been deployed in the blockchain network, to compile a bytecode of the bytecodes of the smart contract into a first machine code by using ahead-of-time (AoT) compilation and storing the first machine code;
• and
• performing, by the blockchain node of the blockchain network in execution of the smart contract and in response to the first machine code of the smart contract not being locally stored, just-in-time (JIT) compilation on a bytecode of the bytecodes of the smart contract to obtain a second machine code and storing the second machine code, and executing the second machine code,
• wherein the performing, by the blockchain node of the blockchain network in the execution of the smart contract and in response to the first machine code of the smart contract not being locally stored, JIT compilation on the bytecode of the bytecodes of the smart contract includes:
• querying, by the blockchain node of the blockchain network in the execution of the smart contract, a current AoT compilation status of the bytecode of the bytecodes of the smart contract in response to the first machine code of the smart contract not being locally stored;
• in response to the bytecode of the bytecodes of the smart contract being in AoT compilation, performing JIT compilation on the bytecode of the bytecodes of the smart contract;
• and
• in response to the bytecode of the bytecodes of the smart contract not being in AoT compilation, starting AoT compilation and performing JIT compilation on the bytecode of the bytecodes of the smart contract.

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

• starting, by a blockchain node of a blockchain network after a smart contract of bytecodes has been deployed in the blockchain network, to compile a bytecode of the bytecodes of the smart contract into a first machine code by using ahead-of-time (AoT) compilation and storing the first machine code;
• and
• performing, by the blockchain node of the blockchain network in execution of the smart contract and in response to the first machine code of the smart contract not being locally stored, just-in-time (JIT) compilation on a bytecode of the bytecodes of the smart contract to obtain a second machine code and storing the second machine code, and executing the second machine code,
• wherein the performing, by the blockchain node of the blockchain network in the execution of the smart contract and in response to the first machine code of the smart contract not being locally stored, JIT compilation on the bytecode of the bytecodes of the smart contract includes:
• querying, by the blockchain node of the blockchain network in the execution of the smart contract, a current AoT compilation status of the bytecode of the bytecodes of the smart contract in response to the first machine code of the smart contract not being locally stored;
• in response to the bytecode of the bytecodes of the smart contract being in AoT compilation, performing JIT compilation on the bytecode of the bytecodes of the smart contract;
• and
• in response to the bytecode of the bytecodes of the smart contract not being in AoT compilation, starting AoT compilation and performing JIT compilation on the bytecode of the bytecodes of the smart contract.
