DOMAIN NAME CONTROL SCHEME FOR CROSS-CHAIN INTERACTIONS IN BLOCKCHAIN SYSTEMS

摘要

FIELD: physics.;SUBSTANCE: invention relates to information processing using blockchain technology. Disclosed solution is aimed at obtaining, by means of a computer system, a unitary blockchain (UBCDN) message for a blockchain instance, wherein the UBCDN message includes a UBCDN instance of a blockchain, a digital signature of the owner UBCDN of the blockchain (UBCDN-owner) for UBCDN and a UBCDN domain certificate, verifying whether the UBCDN domain certificate is issued by the trusted certification authority (CA) or not, using an open CA key and verifying whether UBCDN is issued by the UBCDN owner using the UBCDN public key. UBCDN message includes a blockchain domain name and a chain identifier for a blockchain instance which uniquely corresponds to a blockchain domain name.;EFFECT: technical result consists in expansion of tools range.;12 cl, 8 dwg
