Blockchain data storage based on shared nodes and error correction code

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations for storing blockchain data, the operations comprising:

• determining, by a blockchain node of a blockchain network, block data and current state data associated with a current block of a blockchain;
• sending, by the blockchain node, the current state data to one or more shared storage nodes of the blockchain network, wherein the blockchain node stores the current state data and the one or more shared storage nodes store historic state data associated with every block of the blockchain;
• performing, by the blockchain node, error correction coding of the block data to generate encoded block data, wherein the error correction coding is configured to recover missing bits of original data using the encoded block data;
• dividing, by the blockchain node based on one or more predetermined rules, the encoded block data into a plurality of data sets, wherein the one or more predetermined rules provide an equal distribution of data sets between the shared storage nodes;
• storing, by the blockchain node based on the one or more predetermined rules, one or more data sets that form a portion of the plurality of data sets;
• hashing, by the blockchain node, each data set of remaining data sets of the plurality of data sets to generate one or more hash values corresponding to the remaining data sets;
• and
• storing, by the blockchain node, the one or more hash values and the current state data.

A computer-implemented system for storing blockchain data, comprising:

• one or more processors;
• and
• one or more non-transitory 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 operations comprising:
• determining, by a blockchain node of a blockchain network, block data and current state data associated with a current block of a blockchain;
• sending, by the blockchain node, the current state data to one or more shared storage nodes of the blockchain network, wherein the blockchain node stores the current state data and the one or more shared storage nodes store historic state data associated with every block of the blockchain;
• by the blockchain node, error correction coding of the block data to generate encoded block data, wherein the error correction coding is configured to recover missing bits of original data using the encoded block data;
• dividing, by the blockchain node based on one or more predetermined rules, the encoded block data into a plurality of data sets, wherein the one or more predetermined rules provide an equal distribution of data sets between the shared storage nodes;
• storing, by the blockchain node based on the one or more predetermined rules, one or more data sets that form a portion of the plurality of data sets;
• hashing, by the blockchain node, each data set of remaining data sets of the plurality of data sets to generate one or more hash values corresponding to the remaining data sets;
• and
• storing, by the blockchain node, the one or more hash values and the current state data.
