SPECIAL PURPOSE CRYPTOGRAPHIC INTEGRATED CIRCUIT COMPRISING CONVERSION FUNCTION ENCODED IN CHAIN Russian patent published in 2021 - IPC G06F21/72 G06F21/76 H04L9/06 

FIELD: computational technology.

SUBSTANCE: technical result is achieved by using a programmable conversion unit containing an electronic circuit integrated into the data path circuit of a cryptographic integrating circuit; performing an operation of conversion of the input data received from the data path chain before the programmable conversion unit wherein the data is the blockchain transaction block header; transferring the converted input data to the data path circuit after the programmable conversion unit; applying, using a hashing block and a hashing algorithm on the converted input data; and processing the hashed conversion input data to receive a potential blockchain transaction block header that selectively authorizes during verification at least one between creating an orthogonal blockchain and verifying the blockchain transaction.

EFFECT: increased level of flexibility and security in application of ASIC integrated circuits in blockchain transaction verifying systems.
