METHOD AND APPARATUS FOR VERIFICATION OF CONSISTENCY Russian patent published in 2020 - IPC G06Q20/38 G06F16/27 

FIELD: data processing means.

SUBSTANCE: method of verification of consistency implemented by means of the first unit of blockchain in matched network may contain: receiving a transaction request from a client and performing first security verification with respect to the transaction request; in response to determination that transaction request has passed first security verification, storing a transaction request and broadcasting a transaction request to each of the second blockchain in the coordinated network, causing each second unit of the blockchain to store the transaction request in response to the second unit of the blockchain unit determining that the transaction request has passed the second security verification; performing preprocessing with respect to at least one stored transaction request in response to determining that a predetermined condition is satisfied to obtain and store a preprocessed block; and broadcasting the obtained preprocessed block to the second nodes of the blockchain, forcing the second units of the blockchain to perform verification of consistency with respect to the obtained preprocessed block.

EFFECT: technical result consists in improvement of data security.
