Diego there is only referring to “the VRR paper” (note the double “R”), i.e. specifically the VR “Revisited” paper of Cowling and Liskov in 2012 (not Oki and Liskov’s ‘88 work, which has a different title).

I wish I could share with you some of the anecdotes I’ve been privy to, having dived into the events and personally interviewed some of the people involved.

The history (or total order!) of consensus is fascinating here, almost like a Greek island, but only a few people will ever know it.
