S16 E39: Karl Kreder (Dr. K) on Scaling Proof of Work, Bitcoin & Quai
Episode 39
Monday, 18 August, 2025
Karl Kreder, better known as Dr. K, is best known in the space for researching the use of merged-mined subnets to scale Proof of Work in 2018 – a concept which led to the launch of the Quai Network, which introduced the Proof of Entropy Minima (PoEM) consensus for high transaction throughput within a decentralized environment. Today, we talk about his views on Bitcoin, why Proof of Work is still relevant in a world that's converging towards the more convenient Proof of Stake, and how the Quai Network works.
