Shared blockchain data storage based on error correction coding in trusted execution environments

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

• receiving a request from an application component of a blockchain node to execute a software instruction in the TEE;
• determining a block stored on the blockchain node for executing the software instruction, wherein the block is stored on the blockchain node and appended to a blockchain;
• performing error correction coding of the block in the TEE to generate an encoded block;
• dividing the encoded block into a plurality of datasets based on the software instruction;
• selecting plurality of datasets from the plurality of datasets of the encoded block based on the software instruction;
• and
• encrypting the plurality of datasets to generate one or more encrypted values corresponding to the plurality of datasets, the one or more encrypted values being used for replacing the plurality of datasets to save storage space of the blockchain node.

A computer-implemented system for processing blockchain data by a blockchain node of a blockchain network in a trusted execution environment (TEE), comprising:

• one or more processors;
• and
• one or more computer-readable memories coupled to the one or more processors and having instructions stored thereon that are executable by the one or more processors to perform one or more operations for:
• receiving a request from an application component of a blockchain node to execute a software instruction in the TEE,
• determining a block stored on the blockchain node for executing the software instruction, wherein the block is stored on the blockchain node and appended to a blockchain,
• performing error correction coding of the block in the TEE to generate an encoded block,
• dividing the encoded block into a plurality of datasets based on the software instruction,
• selecting plurality of datasets from the plurality of datasets of the encoded block based on the software instruction, and
• encrypting the plurality of datasets to generate one or more encrypted values corresponding to the plurality of datasets, the one or more encrypted values being used for replacing the plurality of datasets to save storage space of the blockchain node.
