METHOD FOR REACHING CONSENSUS ON PUBLIC DISTRIBUTED LEDGERS AND SYSTEM USING THE SAME

Abstract:

A method for reaching consensus on public distributed ledgers and a system using the same are disclosed. The method includes: obtaining a random data of the last block of a blockchain; comparing the random data with an address of an account to obtain a degree of similarity; filtering accounts based on the degree of similarity; performing further filtering based on the account balance; performing ultimate filtering based on a combination of the account address and the random data; and determining an account that is entitled as the beneficiary to produce a new block to be attached to the last block of the blockchain. The present disclosure reaches consensus of generating a new block through multiple levels of filtering, thereby reducing the power consumption caused by large amounts of computations during the ordinary mining process, while significantly improving the efficiency of blockchain transactions and ensuring the fair distribution of mining rights.
