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…
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…

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…
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…
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…
