# Berlin Ethereum Day Source: https://berlinethereumday.com ## Summary Berlin Ethereum Day, a free one-day event on June 15, 2026 at Funkhaus in Berlin, offers sessions with Ethereum Foundation and ecosystem speakers on Ethereum's technical direction, core values and roadmap. The schedule covers topics including FOCIL, a censorship-resistance mechanism described as EIP-7805 and slated for the Hegotá fork, which the Right of Audience talk by Sina presents as a protocol-level property. Other sessions include Solidity and Argot's language roadmap, ERC-7730 clear signing led by Kaan Uzdogan, and Walletbeat's rating of wallets against CROPS values. ## Article BerlinEthereum Day June 15, 2026·Funkhaus, Berlin Free to attend · Application via Pretix Register to Attend Ethereum was built as an enduring infrastructure for a free, open, and permissionless world, where users retain control over their digital lives and self-sovereignty. Join us in Berlin for a full day of sessions with speakers from the Ethereum Foundation and the broader ecosystem, exploring Ethereum's future - its technical direction, core values, and the road ahead. Schedule Subject to change 10:00 - 10:15 Opening Remarks OtherOther Eniko & Martin · Ethereum Foundation 10:15 - 10:35 Testing the strawmap Talk (20 min)Core Protocol Pari · Ethereum Foundation Plan on how to ship our roadmap 10:35 - 10:45 Coordinating Ethereum Lightning (10 min)Core Protocol Mario Havel · Ethereum Foundation Building a large scale FOSS protocol with zero downtime 10:45 - 11:05 Securing Ethereum: Trust No Single Witness Talk (20 min)Core Protocol Bhargava Shastry · Ethereum Foundation Ethereum has no ground truth but only independent clients that can disagree, so a bug is just a disagreement. This talk covers how we manufacture those disagreements with nightly differential EVM fuzzing across multiple execution layer clients, how we triage the ones the world reports through the EF bug-bounty program, and why every oracle (fuzzer, AI, reporter) is fallible enough that a human still has to break the tie. 11:05 - 11:25 Shipping faster forks (and a sustainable protocol) Talk (20 min)Core Protocol Guillaume Ballet · Ethereum Foundation 11:25 - 11:45 Right of Audience: a case for FOCIL Talk (20 min)Core Protocol Sina · Ethereum Foundation Ethereum was built to be neutral. Yet at peak, 79% of Ethereum blocks were committed to censoring valid transactions, after Tornado Cash was added to the OFAC list. Today, a handful of builders and relays still carry the vast majority of inclusion decisions, while nine hundred thousand validators have no real say over the blocks they sign. This talk makes the case that censorship resistance has to be a property of the protocol, not a market outcome. I'll walk through FOCIL (EIP-7805, shipping in Hegotá): how a randomly-selected committee of validators per slot can force-include transactions, why a 1-of-N honesty assumption is enough, and how the fork-choice rule enforces it. Every valid transaction has a right of audience, because every validator has a voice. 11:45 - 12:05 What's next for Solidity & Argot Talk (20 min)Smart contracts & Dev tools Jacob Czepluch · Solidity (Argot Collective) The presentation will give a high level overview of the current state of Solidity and the future plans for the language. It will also give a brief introduction to Argot, the organization developing Solidity, Sourcify, fe, act, hevm and ethdebug 12:05 - 12:25 Fixing Stack Too Deep Talk (20 min)Smart contracts & Dev tools Moritz Hoffmann · Solidity (Argot Collective) We aim to address two long-standing pain points with an overhaul of the viaIR backend: Going from Yul to an SSA-CFG representation allows us to systematically deal with stack-too-deep as well as bring down compile times. In the talk we will explore some of the status quo of viaIR, dive into aspects of the new backend's inner workings, and peek at what is planned. 12:25 - 12:45 Your one shot Coding Agent for Web3 Talk (20 min)Smart contracts & Dev tools Stephane Tetsing · Remix From idea to deployed contract and distributable frontend in a single prompt. Describe what you want to build; the agent handles the full lifecycle: scaffolding the contract, running security analysis, simulating transactions, and shipping to any EVM chain. It's the entire Remix toolchain, distilled into one conversation. Web3 development used to take a toolbox. Now it takes a sentence. 12:45 - 13:05 Goodbye YOLO Signing Talk (20 min)Smart contracts & Dev tools Kaan Uzdogan · Sourcify (Argot Collective) Blind signing has long been one of Ethereum’s biggest UX and security problems, without an open solution that could address it at the ecosystem level. With ERC-7730 and the new Clear Signing Working Group, that is finally changing. This talk will explain the blind signing problem, the ideas behind ERC-7730 and its registry setup, and showcase Sourcify’s clear signing SDK, which makes it easier for wallets and apps to add human-readable transactions. 13:05 - 13:15 Progress in Open Source Silicon and HW Lightning (10 min)Ecosystem Mark Davis · Open Source chip/wallet Ethereum is open, verifiable, permissionless, and trustless; but chips and HW used to drive inputs into Ethereum are very much not. This is a problem. We summarize the problem, and highlight a few efforts around the world seeking to improve this situation, including but not limited to our own. Crossbar has created the world’s first open MCU/SE, and various HW and SW based on it. We also demonstrate a practical use case, true self-sovereign custody based on complete transparency from silicon to UI. 14:00 - 14:20 Hash based signatures Talk (20 min)Core Protocol Nicolas Consigny · Ethereum Foundation 14:20 - 14:40 Funding the Ethereum Kernel Talk (20 min)Ecosystem Martin Hansen · Ethereum Foundation How we do ensure that Ethereum's critical infrastructure continues to be funded while staying resistant towards capture. 14:40 - 15:00 Overview of the Ethereum Economic Zone Talk (20 min)Ecosystem Friederike Ernst · Ethereum Economic Zone (EEZ) / Gnosis 15:00 - 15:20 Zisk 1.0 Alpha Release: Security, Zk Client Optimizations and EEZ Talk (20 min)Ecosystem Jordi Baylina · ZisK 15:20 - 15:30 L2BEAT Privacy dashboard Lightning (10 min)Ecosystem Sergey Shemyakov · L2BEAT I will showcase a new initial Privacy dashboard on the L2BEAT website and give a glimpse of how we think about privacy protocols at L2BEAT. I will be touching on metrics and risks, as well as some forward facing research around offchain privacy risks, compliance framework and institutional privacy. 15:30 - 15:40 Crosschain State Without the Multisig Lightning (10 min)Ecosystem Danish (nodestarQ) · warptoad Most crosschain apps quietly add a multisig, an MPC committee, or an optimistic oracle on top of otherwise-trustless rollups, silently downgrading every user's security model. They don't have to. Crosschain state can be built using only canonical L1<>L2 messaging plus ZK proofs over a shared root: slower than committee bridges, but with the same security profile as the underlying rollups. No new validators, no new trust assumptions, exit windows intact. I'll walk through the design pattern and ground it in warptoad, a unified-anonymity-set privacy bridge across Ethereum L1, Scroll, and Aztec, where every withdrawal is a ZK proof against a single aggregated GigaRoot. 15:40 - 16:00 CROPS for wallets: Rating Ethereum wallet ecosystem on its own values Talk (20 min)Ecosystem polymutex & Michael · Walletbeat Ethereum is built around a clear set of values: Censorship Resistance, Openness, Privacy, and Security. Users experience Ethereum through wallets, yet most wallets today don't live up to these very values. Walletbeat is L2BEAT for wallets: An open framework that evaluates Ethereum wallets through CROPS values. This talk walks through how CROPS values map to wallets, what the current wallet landscape looks like, and what obstacles exist for wallets to fully embody Ethereum values. We'll cover where the Ethereum wallet ecosystem is making progress, where it's stuck, and what meaningful CROPS alignment actually looks like in practice for modern wallets. 16:00 - 16:20 Kohaku Updates Talk (20 min)Ecosystem Kassandra · Ethereum Foundation 16:20 - 16:40 DWeb: Co-creating resilient communities on the decentralized web Talk (20 min)Ecosystem Raul Romanutti & Beth Mccarthy · Ethereum Foundation & DWeb Camp The Ethereum Foundation's new CROPS mandate - centering Censorship Resistance, Capture Resistance, Open Source, Privacy, and Security - articulates a vision of infrastructure that serves people rather than power. These principles find a natural home in the DWeb Camp community, where decentralization, ecological care, and human agency have long been practiced not just as technical choices but as social and cultural commitments. In this fireside chat, Beth (DWeb Camp) and Raul (Ethereum Foundation, Department of Decentralization) explore where these worlds converge, what each can learn from the other, and how building resilient communities and resilient protocols are ultimately the same project. 16:40 - 17:00 From Open Source to Open Commons: Lessons from FOSSASIA for Ethereum Talk (20 min)Ecosystem Mario Behling · FOSSASIA Mario Behling, founder of FOSSASIA, shares lessons from building open source communities, events, platforms, and contributor ecosystems across Asia and globally. The talk connects this experience with Ethereum’s long-term vision and CROPS principles, arguing that open source is free to use, fork, and adapt, but resilient, private, and secure infrastructure requires sustained funding, maintenance, and trusted ecosystem partners. 17:00 - 17:20 Devcon Updates Talk (20 min)Ecosystem Ornella · Ethereum Foundation (Devcon) 17:20 - 17:40 Where's My Network State Passport? Talk (20 min)Ecosystem Grace Rachmany · Decentralized Identity Foundation Despite all the talk of sovereignty, DAOs as a new form of governance, and Network States, the Web3 communities have not solved the problems of identity. In a world where our governments are creating strong surveillance-enabling identity system, we are still struggling with cross-chain identity, clunky reputation systems, and fragmented systems. Even worse, many of those who declare their commitment to freedom, sovereignty, and privacy are using KYC/AML systems that plug people into the same surveillance systems. What is the state of digital identity in the Web3 and Network State world today, and what would it take to create identity systems that would serve our communities? 17:40 - 18:00 Ideas for the next generation Talk (20 min)Ecosystem Binji · Ethereum Foundation CROPS values are not as abstract as they may seem to a generation that has built their entire identity online. In this talk I will go over what the next generation is looking for and where we can meet them. 18:00 - 18:10 Ethereum Principles Lightning (10 min)Ecosystem Josef Je · EEI 18:10 - 18:15 Eniko · Ethereum Foundation Speakers More to be announced Martin Hansen Ethereum Foundation Raul Romanutti Ethereum Foundation Parithosh Jayanthi Ethereum Foundation Nicolas Consigny Ethereum Foundation Kaan Uzdogan Argot Collective Bhargava Shastry Ethereum Foundation Moritz Hoffmann Solidity / Argot Collective Jacob Czepluch Solidity / Argot Collective Guillaume Ballet Ethereum Foundation Josef Jelacic European Ethereum Institute (EEI) / OWN Friederike Ernst Ethereum Economic Zone (EEZ) / Gnosis Kassandra Ethereum Foundation Grace Rachmany Decentralized Identity Foundation Mario Havel Ethereum Foundation Sina Mahmoodi Ethereum Foundation Ornella Ethereum Foundation Venue Funkhaus Berlin The event will be held at Funkhaus (Nalepastraße 18, 12459 Berlin, Germany), a historic riverside venue known for hosting some of Berlin's most distinctive cultural and technology gatherings.
