Processing blockchain data based on smart contract operations executed in a trusted execution environment

A non-transitory, computer-readable storage medium storing one or more instructions executable by a computer system to perform operations for processing blockchain data under a trusted execution environment (TEE), the operations comprising:

• receiving, by a blockchain node, a request to execute one or more software instructions in the TEE executing on the blockchain node;
• determining, by a virtual machine in the TEE based on the request, data associated with one or more blockchain accounts related to the execution of the one or more software instructions;
• traversing, by the virtual machine, a global state of a blockchain stored in the TEE to locate the data associated with the one or more blockchain accounts;
• generating, by the virtual machine, an updated global state by encoding a hash of a storage content of the one or more blockchain accounts;
• in response to executing the one or more software instructions, generating, by the blockchain node, an encrypted representation of the updated global state;
• and
• storing, by the blockchain node, the encrypted representation of the updated global state in a cache separate from the TEE for cache syncing the encrypted representation of the updated global state to a database of a trusted computing base that is separate from the TEE.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations for processing blockchain data under a trusted execution environment (TEE), the operations comprising:
• receiving, by a blockchain node, a request to execute one or more software instructions in the TEE executing on the blockchain node,
• determining, by a virtual machine in the TEE based on the request, data associated with one or more blockchain accounts related to the execution of the one or more software instructions,
• traversing, by the virtual machine, a global state of a blockchain stored in the TEE to locate the data associated with the one or more blockchain accounts,
• generating, by the virtual machine, an updated global state by encoding a hash of a storage content of the one or more blockchain accounts,
• in response to executing the one or more software instructions, generating, by the blockchain node, an encrypted representation of the updated global state, and
• storing, by the blockchain node, the encrypted representation of the updated global state in a cache separate from the TEE for cache syncing the encrypted representation of the updated global state to a database of a trusted computing base that is separate from the TEE.
