i (54) Title: CONSENUS OF SHARED BLOCKCHAIN DATA STORAGE BASED ON ERROR CORRECTION CODE 
(57) Abstract: Disclosed herein are methods, systems, and apparatus, in
800 cluding computer programs encoded on computer storage media, for storing 
blockchain data. One of the methods includes retrieving a plurality of blocks 
from a blockchain node of the blockchain network, encoding the plurality of 
blocks using error correction coding (ECC) to generate a plurality of encod
ed blocks, and for each encoded block in the plurality of encoded blocks: 
810 2 814 816 dividing the encoded block into a plurality of datasets, calculating hash val
Request Response Com ues of the plurality of datasets, sending a request that includes at least one 
TmstedNode 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, receiving responses for accepting the request from at least a number of 
S BkchainNode -- ---- blockchain nodes that equals a number of the one or more datasets of infor
mation bits, and sending a notification for adopting the data storage scheme.
