BerlinEthereum Day

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.

How we do ensure that Ethereum's critical infrastructure continues to be funded while staying resistant towards capture.

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.

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.

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.

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.

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.

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?

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.
