In this Season 9 episode of The Room Podcast, host Madison McIlwain (joined by Claudia) interviews Kathleen Breitman, co‑founder of the Tezos blockchain. The conversation begins with Kathleen’s personal background—her New York upbringing, education in philosophy, and early exposure to entrepreneurship through her family—then moves into the origins of Tezos. She explains how the limitations of Bitcoin’s immutable code inspired the creation of an on‑chain governance model that allows protocol upgrades without hard forks, and why the team chose proof‑of‑stake (PoS) over proof‑of‑work (PoW) for security and energy efficiency. The discussion details Tezos’s funding approach: a 2017 Swiss‑based Tezos Foundation that raised $232 million via an ICO, the involvement of venture capital (Tim Draper), and the subsequent legal turmoil when foundation head Johann Gevers allegedly withheld funds, leading to six class‑action lawsuits against Kathleen and her husband. Kathleen reflects on the stress of litigation, the importance of “skin in the game,” and how community support (e.g., Founders Forum) helped her navigate the crisis. The interview then shifts to technical road‑maps: Tezos’s pursuit of scalability through optimistic roll‑ups and data‑availability sampling, targeting one million transactions per second—far exceeding Visa/MasterCard throughput—and how this contrasts with Ethereum’s slower upgrade cadence. Kathleen critiques the NFT boom as exposing blockchain limitations, but highlights genuine use‑cases such as low‑fee art marketplaces, real‑estate tokenization in Thailand, and potential decentralized finance (DeFi) applications that add real economic value. She comments on the broader crypto ecosystem’s reputation, noting the 2021 market peak, the distortive effects of the FTX collapse, and how Tezos’s relatively modest, community‑driven growth has persisted. Finally, Kathleen shares perspectives on self‑governance versus regulation, emphasizing censorship resistance, global node distribution, and the need for decentralized decision‑making. She also discusses the intersection of blockchain and the art world, describing collaborations with curators and the Tezos Foundation’s permanent collection. The episode closes with a personal note on women who have influenced her career, particularly her husband’s executive coach Anne Hyatt, and a broader admiration for pioneering women in tech.
