I had the recent privilege of interviewing Brian Oki [1] of Viewstamped Replication in September last year, since VSR is the consensus protocol that we use in TigerBeetle [2] to process a million financial transactions per second. One of the first things that Brian Oki mentioned was Tandem NonStop, and I understand that Brian's VSR was then the first consensus protocol to deal with network partitions, where the network is not reliable, for high availability. What was also special was that James Cowling joined me afterwards—we covered Viewstamped Replication Revisited, the 2012 revision, with a focus in both interviews on Barbara Liskov's influence on both James and Brian.
