CONSENSUS METHOD AND DEVICE BASED ON BLOCKCHAIN Russian patent published in 2020 - IPC G06F15/163 G06F13/38 

FIELD: data processing.

SUBSTANCE: group of inventions relates to means of facilitating data-based consensus based on a blockchain. One blockchain node includes a first server, a second server and at least one database. Method comprises storing, in a data base, consensus data required to perform a consensus procedure, wherein the consensus data are called by the first server and the second server during the consensus procedure; obtaining by second server instead of first data server of consensus from database, and executing a consensus procedure based on the consensus data to generate a consensus result in response to the determination that the first server is faulty before the consensus procedure or during the consensus procedure; and keeping the second server of the consensus result in the database. In compliance with this application, a sound server in a node may receive, instead of a faulty server, consensus data from a database in order to execute a consensus procedure.

EFFECT: technical result consists in improvement of probability of data compliance during implementation of consensus procedure, thereby increasing efficiency of treatment of blockchain service.
