Abstract
A distributed consensus method for performing data consensus processing in a distributed system that couples one or more client apparatuses and a plurality of server apparatuses via a network, the method including a step in which each server apparatus performs data operation according to a predetermined distributed consensus algorithm, a step in which an auxiliary consensus device, which is an auxiliary device that assists in reaching a consensus in the event of a failure in response to a request from each server apparatus, decides an auxiliary consensus decided value, and a step in which the auxiliary consensus decided value is caused to take precedence over the decided value of the distributed consensus algorithm under conditions under which the auxiliary consensus decided value decided by the auxiliary consensus device and the decided value decided by the distributed consensus algorithm can conflict with each other.
