Every year, the Ethereum ecosystem welcomes thousands of builders through community events, hackathons, courses, bootcamps, and campus clubs. However, many newcomers struggle to remain engaged, as they face challenges securing structured early-career opportunities. The Ethereum Season of Internships directly addresses this retention gap by creating a coordinated collection of internship opportunities across the ecosystem. What is the Ethereum Season of Internships? The Ethereum Season of Internships offers a coordinated collection of paid, fully remote summer internships across the Ethereum ecosystem. This initiative creates pathways for the next generation of contributors to connect with Ethereum projects and apply their diverse skills…

Thanks to Marius Van Der Wijden for creating the test case and statetest, and for helping the Besu team confirm the issue. Also, kudos to the Besu team, the EF security team, and Kevaundray Wedderburn. Additionally, thanks to Yuxiang Qiu, Justin Traglia, Marius Van Der Wijden, Benedikt Wagner, and Kevaundray Wedderburn for proofreading. If you have any other questions/comments, find me on twitter at @asanso tl;dr: Besu Ethereum execution client version 25.2.2 suffered from a consensus issue related to the EIP-196/EIP-197 precompiled contract handling for the elliptic curve alt_bn128 (a.k.a. bn254). The issue was fixed in release 25.3.0. Here is…

Bit Digital shifts treasury from Bitcoin (BTC) to over 100K ETH. Dormant Ethereum wallets move millions after 10 years. ETH/BTC bull flag hints at a 35% breakout by August. Ethereum (ETH), the world’s second-largest cryptocurrency by market capitalisation, is stepping into what many believe could be a transformative phase, marked by growing institutional alignment and renewed on-chain activity from long-dormant whales. Momentum around the asset has intensified in recent weeks, with fresh technical setups, corporate accumulation, and protocol-level proposals all converging to highlight Ethereum’s evolving position as not just a programmable blockchain but also a premier financial infrastructure layer. Dormant…

As of today, all Ethereum execution clients support partial history expiry in accordance with EIP-4444. While work on full, rolling history expiry is ongoing, users can expect to reduce the disk space required for an Ethereum node by 300-500 GB by removing the block data prior to the Merge. This will allow a node to fit comfortably on a 2 TB disk. See below for information on each specific client. Chain history By definition a blockchain is a chain of blocks starting at a specific genesis point. For Ethereum, that occurred on July 30, 2015. Each block includes information about…

Katana mainnet launch is around the corner after over $200 million in productive DeFi deposits. Katana’s VaultBridge and CoL mechanisms will power yield and liquidity efficiency. Katana supports cross-chain assets like SOL, XRP, and SUI on-chain. Katana, a new DeFi-centric layer-2 blockchain built on Ethereum, has people on tentacles amid its highly anticipated mainnet launch after drawing more than $200 million in active deposits and setting a new benchmark for liquidity-focused networks this year. The launch, which comes just weeks after Katana’s public reveal, is causing excitement across the crypto community due to its impressive capital inflow and unique design,…

Ethereum stands at the edge of major breakthroughs. zkEVMs have rapidly accelerated, enabling us to rearchitect L1 to simultaneously support scale, verifiability, security and censorship-resistance. L2s are hardening, meeting users where they are, and eager to double down on using Ethereum as their root of trust. In short, the world is ready for the world computer. These significant innovations both unlock massive benefits for our users and will allow us to onboard many, many more. The stakes are high: This moment may be Ethereum’s best shot at deploying not only our technology, but our values, at planetary scale. As a…

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 4-5 weeks, depending on what’s happening in core development. See the previous update here. tl;dr: Since the last Checkpoint, the Pectra upgrade shipped and core developers have maintained a heavy emphasis on keeping the next upgrade (Fusaka) lean to get PeerDAS, a scaling unlock, out the door. Fusaka testing is ongoing and developers are still optimistic about a 2025 release date. Proposals for the headlining feature of the upgrade following Fusaka (”Glamsterdam”, ~2026) are being solicited until…
