Abstract: A method for intelligently selecting an accounting node of a blockchain, relating to fields of blockchain, virtual currency and artificial intelligence, is provided, including steps of: (1), based on block data, calculating a node capability value of each accounting node; (2), making statistics of threshold values of the node capability values of every node; and (3), according to the threshold values, determining a current accounting node, and thereafter randomly selecting other nodes, so as to complete node selection. According to the present invention, based on block data and miner data of various dimensions, an intelligent distribution mechanism of accounting rights or mining rights is adopted; and meanwhile, a random distribution of accounting rights or mining rights is also adopted for avoiding hacker attacks. Therefore, on a premise of guaranteeing fairness, decentration and safety of the blockchain, problems of energy waste and low accounting efficiency due to mining conflict are solved.
