Abstract
A computer-implemented method includes: retrieving a plurality of blocks from a blockchain node of a blockchain network. The plurality of blocks are encoded using error correction coding (ECC) as encoded blocks. For each encoded block: The encoded block is divided into a plurality of datasets. Hash values of the plurality of datasets are calculated. A request that includes at least one of the plurality of datasets, the hash values, and a data storage scheme that provides assignments of the plurality of datasets to the plurality of blockchain nodes is sent to each of the plurality of blockchain nodes of the blockchain network. Responses for accepting the request is received from at least a number of blockchain nodes that equals a number of the one or more datasets of information bits. Each of the plurality of blockchain nodes is sent a notification for adopting the data storage scheme.
