> It is my understanding that the motivation in seeking out consensus algorithms with strong leaders (or equivalent) as opposed to horizontally weighted peer-to-peer ones is due to the performance penalty imposed by the latter in the general case.
Yeah, that was my understanding as well but without having read the paper in question (as of yet) I'm entirely short on the particular technical details of the trade-offs.
- stelfer 10y agoI didn't read the whole thing carefully, but... Leader Election + Terminating Reliable Broadcast is practically equivalent to building the Weakest Failure Detector and is the most feasible way of doing so. So, there are good reasons for doing leader election. This is why almost every serious consensus system ends up doing it whether they know they need to or not.
