Industrial Automatic Control Systems and Controllers Annotation << Back Implementation of Directed Acyclic Graph in Blockchain Network to Improve Security and Speed of Transactions in Industry I.D. Kotilevets, I.A. Ivanova The article describes the advantages of introducing a directed acyclic graph into the blockchain network of an industrial enterprise. A method of increasing the transaction speed between network participants and scaling the channel width based on the formation of parallel chains instead of the only true one in conventional blockchain networks is proposed. This allows to increase the speed of the network and the number of participants. Keywords: blockchain; telecommunication network; information security; transaction; scalability; directed acyclic graph. Contacts: E-mail: ikotilevets@gmail.com, E-mail: mgupirabota@bk.ru Pp. 53-59.
