Dynamic blockchain data storage based on error correction code

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

• receiving a request for performing error correction coding (ECC) to one or more blocks of a blockchain;
• obtaining the one or more blocks based on blockchain data received from at least one second blockchain node of the blockchain network;
• and
• performing ECC of the one or more blocks to generate one or more encoded blocks, wherein a code rate of the one or more encoded blocks equals a minimum number of honest blockchain nodes required by the blockchain network and a total number of blockchain nodes of the blockchain network.

A computer-implemented system for processing blockchain data performed by a first blockchain node of a blockchain network, the 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 operations comprising:
• receiving a request for performing error correction coding (ECC) to one or more blocks of a blockchain;
• obtaining the one or more blocks based on blockchain data received from at least one second blockchain node of the blockchain network;
• and
• performing ECC of the one or more blocks to generate one or more encoded blocks, wherein a code rate of the one or more encoded blocks equals a minimum number of honest blockchain nodes required by the blockchain network and a total number of blockchain nodes of the blockchain network.
