Raft? The two most prominent consensus algorithms that I usually come across in 'the wild', are Paxos and Raft. Am I missing something -- or is the article missing something?
Here's a nice paper on this that dives deeper into the matter and also shows how Paxos can be just as "understandable" as Raft with a few vocabulary changes: https://arxiv.org/pdf/2004.05074.pdf
A more recent development is Heidi Howard's work, which provides a framework for thinking about the whole category of Paxos algorithms that many of us find a lot more approachable.
Glad someone has mentioned her here. This talk helped me greatly https://www.youtube.com/watch?v=KTHOwgpMIiU.
