tl;dr: Ethereum Protocol Studies is returning for 2025. Visit epf.wiki to fill out the survey and join the town hall on Wednesday, Feb 12. The Ethereum Protocol Studies program (EPS) is back for 2025! Designed to lower the barrier to understanding Ethereum’s core protocol, EPS provides structured learning and a direct path to deeper protocol knowledge. Expanding Learning Resources Over the past year, we’ve created a curriculum covering foundational Ethereum concepts available to help onboard new participants. These recordings serve as an invaluable resource for newcomers and seasoned builders alike. Some highlights of the curriculum include this session on data…

[05/03/2025] Sepolia Incident Update See this post. [27/02/2025] Holesky Incident Update On Feb. 24, 2025, the Pectra upgrade activated on the Holesky testnet. After the activation, a configuration issue in Besu, Nethermind and go-ethereum led to a chain split on Holesky. The issue was rapidly fixed, but the Holesky network performance is still degraded. More details on the incident can be found here. Sepolia Network Upgrade The Sepolia network upgrade timing is unchanged. The network is expected to fork at epoch 222464 (Mar. 5, 7:29 UTC). Node operators using the Besu, go-ethereum, Nethermind or Lodestar clients MUST upgrade their client…

Ryuta Aoki Ryuta is an artist, artistic director, conceptual designer, system architect, software engineer, entrepreneur, and social sculptor based in Tokyo. Ryuta describes his Learning Artifact, SOTOROJI, as part of a series of spatial devices that lead from the ordinary to the extraordinary, utilizing the modern social affordance of “seeing a QR code and scanning it with a camera,” just as soto-roji (the outer garden) in the Japanese tea ceremony serves as a space leading to a world of profound subtlety. SOTOROJI was featured as an art piece at the Devcon venue, viewed by thousands of attendees. Source link

Today, we’re excited to announce the Pectra Audit Competition, kicking off on Cantina! This month-long event will run from February 21 to March 24, and we’re excited to see what issues the security community can find. Why Pectra Matters Some of the key EIPs for Pectra are listed below From EOAs to Smart Accounts (EIP-7702) Enhances Externally Owned Accounts (EOAs) with smart contract features. Key Benefits Transaction Batching: Combine multiple operations into a single transaction.Gas Sponsorship: Others can pay fees for the account.Alternative Authentication: Use hardware security modules or passkeys for authorization.Spending Controls: Limit token usage/outflows for improved security.Recovery Mechanisms:…

My dear Ethereum community, Today, I’m excited to turn the page and share that I will be closing this chapter as Executive Director of the Ethereum Foundation soon and stepping into a new role as its President. This new opportunity will allow me to continue supporting EF’s institutional relationships, and to expand the reach of our vision and culture more broadly. I’m feeling deeply grateful and enthusiastic for what’s ahead, and while I made this decision a year ago, recent events have given me the perfect opportunity to reflect on what truly matters to me. These past few weeks have…

The security of the Ethereum protocol is continually being improved, and one recent effort is the external security review of the Pectra System Contracts. The results of this review can be found in the audits repository, and the TL;DR is that all discovered issues deemed relevant or important from these reviews have been addressed. Audit Scope and Methodology The Pectra System Contracts encompass several EIPs (EIP-2935, EIP-7002, and EIP-7251), and reviews were primarily done to: Evaluate the contracts for potential attack vectors.Ensure that the contract logic accurately implements the intended functionality as per the EIP specifications. A multi-phase approach was…

The Ethereum Foundation is thrilled to announce a new leadership structure, welcoming Hsiao-Wei Wang and Tomasz Stańczak as co-Executive Directors effective March 17th.

We’re excited to announce that the next Devconnect will be held in Buenos Aires, Argentina, from November 17th to the 22nd, 2025 at the iconic venue La Rural! This year, we are aiming for something bigger than just Devconnect: We want to support an effort that the local community has already started — bringing Argentina onchain. In Buenos Aires and Argentina, we have a city and country that have been leading adopters of Ethereum for many years. Devconnect Argentina is an opportunity for the whole Ethereum ecosystem to support that steady growth and to accelerate it even further, by helping…

At 7:29 UTC today, on epoch 222464, the Pectra network upgrade went live on the Sepolia testnet. Unfortunately, an issue with Sepolia’s permissioned deposit contract prevented many execution layer clients from including transactions in blocks. The root cause was identified within minutes, and client teams immediately began working on a fix. This issue is due to Sepolia’s configuration and could not occur on the Ethereum mainnet. Around 14:00 UTC today, validators deployed a fix that restored the network to normal throughput. All Sepolia node operators must now upgrade their execution layer clients to the versions listed below to maintain network…
