i (54) Title: PRIORITIZING SHARED BLOCKCHAIN DATA STORAGE 
600 (57) Abstract: Disclosed herein are methods, systems, and apparatus, in
cluding computer programs encoded on computer storage media, for storing 
blockchain data. One of the methods includes receiving a plurality of blocks 
Blacain 610 from a blockchain node in the blockchain network; for each of the plurality 
netwk / of blocks: determining a first number of blockchain nodes that store a dataset 
divided from an error correction coding (ECC) encoded version of the block 
and a second number of blockchain nodes that store a dataset comprised of 
Sendblock date redundant bits divided from the ECC encoded version of the block; calculat
ing a priority value of the block based on the first number and the second 
number; and encoding at least a portion of the plurality of blocks using ECC 
---------- to generate a plurality of encoded blocks based on the priority value.
