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.

System and method for distribution storage of blockchain transaction data based on erasure code

A method for transmitting agreed data on a network by an electronic apparatus, the method according to an embodiment of the present invention may include the steps of storing a generation matrix generated on the basis of the number of a plurality of electronic apparatuses including the electronic apparatus participating in the network and the number of a plurality of data blocks to be shared between the plurality of electronic apparatuses and transmitting an agreed data block agreed to be shared with another electronic apparatuses included in the plurality of electronic apparatuses to another electronic apparatus on the basis of the generation matrix.

Agreed data transmit method and electronic apparatus for transmitting agreed data in network

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.
