About this episode
Yonatan Sompolinsky is an academic in the field of computer science, best known for his work on the GHOST protocol (Greedy Heaviest Observed Subtree, which was cited in the Ethereum whitepaper) and the way he applied his research to create Kaspa.
In this episode, we talk about scaling Proof of Work and why Kaspa might be a worthy contender to process global payments.
