In this episode, Aaron talks with Joran Greef, CEO and creator of TigerBeetle, the world’s first financial transactions database. Joran takes us on a deep dive of on how TigerBeetle brings double-entry accounting principles directly into the database layer to achieve extreme correctness, performance, and fault tolerance at scale.
