Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing blockchain data under a trusted execution environment (TEE). One of the methods includes receiving, by a blockchain node, a request to execute one or more software instructions in a TEE executing on the blockchain node; determining, by a virtual machine in the TEE, data associated with one or more blockchain accounts to execute the one or more software instructions based on the request; traversing, by the virtual machine, a global state of a blockchain stored in the TEE to locate the data; and executing, by the virtual machine, the one or more software instructions based on the data.
