Public Tech Talk: "A Semi-Topological View of Real-World Consensus" by Dr. Jamie Gabbay



In the real world, people join humanity, grow up trusting very different quorums from one another, and they may change their quorums with time. In technical terms we could call this an open permissionless system with mutable local quorums.

One might expect such a system to be a jumbled disorder โ€” and yet, somehow, it self-organises into uniform areas of fairly stable consensus. One might almost suspect there could be some deep mathematical principles involved!

In this talk I will discuss consensus in a permissionless open system with mutable local quorums, and show how a topological view of the system gives a clean mathematical analysis with surprisingly good explanatory power.
