BLOCK CHAIN ​​DELEGATION SYSTEMS AND METHODS WITH OPTIMAL LEDGER DISTRIBUTION AND COMPUTER-READABLE MEDIA

Abstract

The invention relates to a blockchain authorization system and a blockchain authorization method with a distributed ledger and associated computer-readable means, comprising an authorization server, an authentication device, and a blockchain, where the authorization server acts as the single administrator node to provide authentication requests from multiple Internet of Things (IoT) devices to the authentication device for verification, and after the authentication requests pass the verification, the authorization server authorizes itself and / or the blockchain nodes to create blocks according to the optimal route planning and optimal ledger node combination. Thus, the invention can avoid double-spending and improve the efficiency of the blockchain system while enhancing the information security of the authorization system.
