1. A computer-implemented method for storing blockchain data, the computer-implemented method comprising:

  • obtaining, by a first blockchain node, a first hash value corresponding to a first historic state data item;

    identifying, by the first blockchain node and based on one or more predetermined rules, a second blockchain node that stores at least a first encoded data item, wherein the first encoded data item is generated based on the first historic state data item and an error correction coding process;

    sending, by the first blockchain node, the first hash value to the second blockchain node for retrieving the first encoded data item; and

    in response to sending the first hash value to the second blockchain node, receiving, by the first blockchain node, the first encoded data item from the second blockchain node.
