Despite technical improvements in throughput, MEV-related spam continues to consume a large share of added capacity, effectively neutralizing scaling gains. Flashbots estimates that MEV bots consume 40–50% of blockspace, driving up base fees for users. Bots often send hundreds of transactions for a single low-margin arbitrage. While profitable for the bots, it’s wasteful for the network, burdening nodes and users. To use blockspace more efficiently, Flashbots proposes replacing the current spam auction system with programmable privacy and auction-based MEV markets. Next Billion Cohort 5 Fellows ----------------------------- The Ethereum Foundation [announced](https://blog.ethereum.org/2025/06/16/world-experience) the four fellows selected for the fifth cohort of the Next Billion Fellowship. The fellows are working on projects in areas spanning digital identity, climate finance, and emergency response. Each fellow will share their work with the broader community by the end of the program. Applications are now open for the sixth cohort, beginning in October 2025. The Next Billion Fellowship is a non-technical program designed to support individuals building human-centered projects that use Ethereum for social impact. Fellows receive financial support, mentorship, and access to Ethereum Foundation resources.
