tl;dr: Over the last couple of days, some L2s noticed that their deployments on Sepolia didn’t work properly anymore. This is due to EIP-7594 which changes the format for proofs. In anticipation of Fusaka, we urge all blob originators to update their software to create Cell Proofs instead of blob proofs. Background One underdiscussed aspect of EIP-7594 (PeerDAS) is that it changes the format for proofs from blob proofs to cell proofs. This allows for downloading a specific part of the blob instead of the whole blob for data availability sampling. This change might break user applications that send blob…
Ethereum (ETH) holds near $3,000 as institutions accumulate despite mixed short-term sentiment. Strong staking, wallet growth, and ETF inflows support Ethereum’s price floor. ERC-8004 could unlock AI-driven on-chain demand and long-term ETH value. Ethereum is entering a pivotal phase as price action, institutional flows, and protocol-level innovation begin to converge. After a volatile start to the year, ETH has reclaimed the $3,000 level, signalling renewed confidence among both traders and long-term holders. At the time of writing, Ethereum is trading near $3,010, with a market capitalisation of roughly $364 billion and a 24-hour trading range between $2,899 and $3,028. This…

Starting with the upcoming Fusaka hard fork, EIP-7825 introduces a per-transaction gas limit cap of 2²⁴ (≈ 16.78 million gas). This change is already live on Holesky and Sepolia, and will activate on mainnet with Fusaka. Developers and users who rely on very large transactions should verify that their contracts and transaction builders conform to the new cap. Background As Ethereum scales to higher block gas limits and prepares for parallel execution (e.g. EIP-7928 in Glamsterdam), the Fusaka fork introduces a per-transaction gas limit cap. Previously, a single transaction could consume the entire block gas limit (~45 million gas), creating…
Over the past few years, the Ethereum ecosystem has grown in depth, diversity, and maturity. Builders and communities worldwide have pushed the boundaries of what’s possible, creating new tools, protocols, and public goods that strengthen the network as a whole. As the ecosystem grows, our approach to supporting it must adapt as well. Today, we’re excited to share the next step in that journey: the Ecosystem Support Program’s (ESP) new grants program. This announcement builds on our earlier update, where we temporarily paused open grant applications to reassess our priorities and funding approach. During this time, we focused on designing…
In two weeks, we open the doors to the first-ever Ethereum World’s Fair at La Rural in Buenos Aires. This year isn’t about someday. It’s about now. On Ethereum today you can pay, play, vote, save, borrow, lend, and chat, all onchain — and at Devconnect you’ll experience that shift hands-on, IRL.Buenos Aires is the right backdrop for this moment: a city where crypto is part of daily life and where builders are ready to show what’s live. Below is your guide to what’s inside the fairgrounds, how to plan your week, and what to do before you arrive. Inside…
Fusaka follows this year’s Pectra upgrade, representing a major step forward in Ethereum’s scaling roadmap that improves L1 performance, increases blob throughput, and enhances user experience. The Fusaka network upgrade is scheduled to activate on the Ethereum mainnet at slot 13,164,544 (December 3, 2025, 21:49:11 UTC). Fusaka also introduces Blob Parameter Only (BPO) forks to safely scale blob throughput after PeerDAS activation. These are minimal, config-only upgrades that adjust the blob target/max and fee update fraction. See the activation table below for further details. The Fusaka mainnet client releases are listed below. Fusaka Overview Fusaka’s headlining feature is PeerDAS (Peer…
Ethereum’s weekly All Core Developer calls are a lot to keep up with, so this “Checkpoint” series aims for high-level updates roughly every 4-6 weeks, depending on what’s happening in core development. See the previous update here. If you enjoy reading core development updates, you may also be keen to learn that Forkcast now publishes call summaries, chats and transcripts for each All Core Devs call, usually available within a couple hours of the call. tl;dr: The Fusaka upgrade is nearly out the door, Glamsterdam is ramping up, with its major features in implementation and minor features being decided on.…
Disclaimer: The following blog is a proposal from the Account Abstraction team. Content may not imply consensus views, and the EF is a broad organization that includes a healthy diversity of opinion across Protocol and beyond that together strengthen Ethereum. Since the early days of Ethereum, the promise has always been bold: a global, permissionless, censorship-resistant computing platform. Today, that promise is more alive than ever. Ethereum has scaled through rollups, where blockspace is abundant and transactions are cheap. The challenge now is not just throughput, but seamless user experience across that multichain horizon. What if all the L2s felt…
