Is The Future of Ethereum Centralised and Censored?
Epicenter - Learn about Crypto, Blockchain, Ethereum, Bitcoin and Distributed TechnologiesShow Notes
In this episode, host Friederike Ernst is joined by Thomas Thiery, a researcher at the Ethereum Foundation, to discuss EIP-7805 and the implementation of FOCIL (Fork-Choice Enforced Inclusion Lists). Thomas explains how the rise of MEV (Maximal Extractable Value) has created a centralized builder market where a few actors now control over 85% of Ethereum's block production, creating a dangerous bottleneck for censorship. FOCIL addresses this by empowering a decentralized committee of 16 validators to mandate transaction inclusion, making any block that ignores these lists invalid.
They explore the "Tornado Cash" moment and the risks of "silent censorship" for competitive or regulatory reasons. Thomas explains why FOCIL intentionally prioritizes the public mempool over MEV-heavy transactions to prevent the system from being co-opted. Finally, the conversation looks at the future of the Ethereum roadmap, including the Osaka fork and the technical trade-offs between inclusion lists and long-term privacy solutions like encrypted mempools.

Ten years after The DAO hack changed Ethereum forever, Griff Green returns to Epicenter to discuss the next chapter: the DAO Security Fund.
Jason Yanowitz, Co-Founder of Blockworks, joins Sebastien Couture on Epicenter to discuss why crypto is entering its biggest transformation yet. From institutional adoption and the Clarity Act to token transparency, AI, on-chain capital markets and the acquisition of Messari, this conversation explores where crypto is actually heading.
In this special episode, we revisit a fireside conversation between Vitalik Buterin and Friederike Ernst at DappCon 2026 in Berlin. They explore the Ethereum Economic Zone (EEZ), a new vision for Ethereum built around synchronous composability, app chains, and real-time proving.
In this episode, host Friederike Ernst is joined by Kubi Mensah, CEO and co-founder of Gattaca, the company behind Titan Builder. Kubi sheds light on the highly competitive and often opaque world of Ethereum block building, explaining how Gattaca evolved from a centralized exchange proprietary trading firm to one of the three dominant builders responsible for constructing the vast majority of Ethereum blocks today .
In this episode, host Sebastian Couture is joined by Torab, CEO of Move Industries, to discuss the tension of radical transparency and the decision to scrap Movement's complex L2 architecture in favor of a sovereign L1 powered by the Move VM. He explains how this transition drastically reduced latency and AWS infrastructure costs while improving the builder experience.The conversation explores Movement's core thesis: "Move is for Money". Torab argues that general-purpose L1s are becoming saturated and that Movement's true product-market fit lies in the Global South, serving nations battling currency devaluation.
