Abstract: Provided are an Ethereum Virtual Machine-based transaction processing method and apparatus, a device and a medium, which relate to the field of computer technologies and, in particular, to blockchain technologies and are applicable to the field of cloud computing. An implementation scheme includes: acquiring, by a virtual machine instance running in a blockchain node, a to-be-processed transaction request; in a process of executing the to-be-processed transaction request, generating, by the virtual machine instance, a data access request for target access data and transmitting the data access request to an interface module, where the data access request includes a data read request and/or a data write request; and calling, by the interface module, a blockchain access interface for a data storage space of a blockchain according to the data access request to access the target access data and feeding back an access result to the virtual machine instance.

Abstract: Provided are an Ethereum Virtual Machine-based transaction processing method, a device, a program and a medium. An implementation scheme includes: acquiring, by a virtual machine instance running in a blockchain node, a to-be-processed transaction request; in a process of executing the to-be-processed transaction request, generating, by the virtual machine instance, a data access request for an intra-contract variable and transmitting the data access request to an interface module; performing, by the interface module, instruction conversion according to the data access request to determine an intra-contract variable access interface corresponding to a function of the data access request; and calling, by the interface module, the intra-contract variable access interface for a contract space in a data storage space of a blockchain to access the intra-contract variables in the contract space and feeding back an access result to the virtual machine instance.
