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 in a trusted execution environment (TEE) executing on a computing device communicably coupled to a blockchain network, comprising:

• receiving a request from a blockchain node of the blockchain network to execute one or more software instructions in the TEE;
• determining one or more blocks that are infrequently accessed for executing the one or more software instructions, wherein the one or more blocks are stored on the blockchain node and are appended to a blockchain;
• performing error correction coding of the one or more blocks in the TEE to generate one or more encoded blocks;
• dividing each of the one or more encoded blocks into a plurality of datasets based on the one or more software instructions, wherein each dataset of the plurality of datasets is stored on a separate blockchain node of blockchain nodes of the blockchain network;
• and
• sending the plurality of datasets and a data storage arrangement to the blockchain nodes based on the one or more software instructions, wherein the data storage arrangement indicates at least one of the plurality of datasets to be stored by each of the blockchain nodes.

A computer-implemented system for processing blockchain data in a trusted execution environment (TEE) executing on a computing device communicably coupled to a blockchain network, 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 a blockchain node of the blockchain network to execute one or more software instructions in the TEE;
• determining one or more blocks that are infrequently accessed for executing the one or more software instructions, wherein the one or more blocks are stored on the blockchain node and are appended to a blockchain;
