  • System and method for distribution storage of blockchain transaction data based on erasure code
    Patent number: 12283974
    Abstract: Provided is a method performed by a system for distribution storage of blockchain transaction data based on an erasure code. The method includes performing RS encoding on a predetermined number of blockchain transaction original data; and after the RS encoding is performed, applying LRC encoding technique to blockchain transaction original data (LRC-encoded original data), which needs to be accessed high speed, among the RS-encoded transaction original data to encode and store the LRC-encoded original data, and repairing the LRC-encoded original data through decoding.

  • Controller, semiconductor memory system and operating method thereof
    Patent number: 10439647
    Abstract: An operation method of a controller includes: generating a predetermined number of sub-messages by dividing an original message; generating a first parity added message by adding a cyclic redundancy check (CRC) parity message of a predetermined length to each of the sub-messages; and generating an encoded message by performing a polar encoding operation to the first parity added message.
