Abstract
A distributed system uses a consensus protocol to maintain a data set shared by nodes of the distributed system. When a change is proposed to the data set, the change must pass multiple tests, including a test regarding the validity of the proposed change according to the consensus protocol and a test regarding the validity of the proposed change according to an application that utilizes the data set. As a result, poison pills that could harm operation of the distributed system are prevented from being accepted, regardless of whether such poison pills would satisfy any conditions of the consensus protocol.
