POWERED BY THE ETHEREUM FOUNDATION

Trustlessness is Ethereums foundation. Without it, we recreate the old internet of intermediaries and gatekeepers. With it, we can build systems that are open, neutral, and censorship-resistant.

Ethereum today is powerful but fragmented across rollups. Each chain is its own silo, and without trustless interoperability we risk recreating the old internet of walled gardens.

Ethereum Interop Layer (EIL) is that protocol.

It makes multichain feel like single-chain, but without handing power to centralized solvers, custodians, or trusted bridges. Instead, wallets themselves become the interface for cross-rollup execution, ensuring settlement remains verifiable, neutral, self-custodial and credibly neutral.

EIL is not just infrastructure - it’s how we scale Ethereum’s trustlessness to the internet of blockchains.

FOCIL: Restoring Censorship Resistance on Ethereum

A brief history of censorship resistance on Ethereum, followed by an overview of FOCIL (EIP-7805) and its role in restoring credible neutrality and trustlessness. This talk explains how multi-proposer inclusion lists provide robust protocol-level inclusion guarantees and why this EIP is essential to reestablish Ethereum as the most reliable venue to transact onchain.

Interop Risk Framework by L2BEAT

During DevCon Bogota L2BEAT introduced a simple risk framework for bridges. The interop space has evolved significantly since then and we believe that a new comprehensive risk framework for interop is needed not only to surface risks to users, but similarly to Stages framework for L2s to set guidelines and expectations for the teams building trustless solutions

Panel: Banks won’t go onchain until we fix privacy

Public blockchains are transparent by design - an uncomfortable reality for banks that handle confidential client and operational data. This panel unpacks why privacy is the missing piece preventing institutions from fully embracing onchain finance. Together with experts from leading banks and the Ethereum ecosystem, we’ll explore regulatory compliance through zero-knowledge proofs, user and institutional privacy, and the balance between transparency, trustlessness, and confidentiality in decentralized systems.

Kohaku Koi Fish at the Ethereum Foundation

WalletBeat is a wallet dashboard that we kickstarted a few months ago thanks to a highly motivated anonymous contributor. I will be explaining the values and criteria behind the wallet ranking. Most importantly I will show how you as a wallet user or wallet dev can contribute to this great project.

Why Contract Verification Needs to Open Up

Source code verification is the basis of trustlessness in Ethereum. Contracts are just a black box without verified code. Ethereum has good verification culture and expects contracts to be verified. But despite its importance, the status quo in verification itself is suboptimal and does not align with Ethereum's values. Verifiers/Explorers are closed-source, the contract datasets are closed and centralized, and the UX is painful. Sourcify, as a member of the Verifier Alliance is working towards pushing the verification ecosystem to open up and decentralize by sharing contract data, creating better tooling, and enabling interoparability between verifiers.
