About the Ethereum FoundationThe Ethereum Foundation (EF) is a global non-profit organization dedicated to supporting Ethereum and related technologies. Our mission is to do what is best for Ethereum’s long-term success. Our role is to allocate resources to critical projects, to be a valued voice within the Ethereum ecosystem, and to advocate for Ethereum to the outside world.EF InternshipAs part of our mission to advance blockchain systems, interns will contribute to bleeding edge research that spans computer science, distributed systems, crypto-economics, and mechanism design. This program offers a unique opportunity to work closely with Ethereum Foundation researchers, their collaborators, and other contributors across the ecosystem, tackling both foundational and applied research challenges. Interns will also have opportunities to share their findings through ethresear.ch, academic publications, or conference submissions helping shape the future of Ethereum.Interns can choose to work remotely but are encouraged to work out of an EF office (likely Berlin, Germany). In addition, interns will be invited for an in-person cohort meetup in the summer.The duration of the internship is 12 weeks during summer 2026.Protocol Consensus team descriptionThe Protocol Consensus team’s mission is to bridge the gap between the guarantees provided by Ethereum’s consensus protocol today and those necessary to fully support the network’s long-term values and objectives. To move toward this goal, we focus on activities such as protocol design, theoretical analysis, specification writing, academia engagement and collaboration with the broader ecosystem to ensure that ideas can be translated into practice.Resources:- TOB-SVD: Total-Order Broadcast with Single-Vote Decisions in the Sleepy Model- Integrating 3SF with ePBS, FOCIL, and PeerDAS- A Fast Confirmation Rule for Ethereum | Devcon SEAMore on the EF Protocol cluster: https://protocol.ethereum.foundation/
