In this week's episode, we go deep on Consensus Algorithms and HotStuff with Ittai Abraham from VMware Research. We chat about the evolution of consensus algorithms, BFT, and how these early ideas have become the backbone of blockchain tech. We cover PBFT, Tendermint and Ittai's research into SBFT, HotStuff, and the improvements he has been working on since HotStuffs incorporation into Facebook's Libra protocol.

Fredrik has a chat about consensus algorithms with Parity Technologies in-house consensus expert Robert Habermeier. We cover what a consensus algorithm is and how they work. We try to explain some common terms like safety and liveness, what a fork choice rule is and how real-world constraints like networking play a role in your algorithm design.
