Coined as Ethereum’s Hyperscale Co-processor, TOOL is a permissionless scaling layer that delivers 1-second finality without protocol or validator changes. It uses sealed-bid auctions to process private orderflow offchain. TOOL connects wallets, traders, RPCs, solvers, and searchers into one permissionless network on Ethereum L1. TOOL is supported by Ethereum’s leading staking providers, including Lido, Rocket Pool, SSV, Obol, and is undergoing a full audit by security firm Sigma Prime.Reserve Launches LCAP Index DTFReserve Protocol launched the Large Cap Index Decentralized Token Folio (LCAP DTF), a single index token representing a basket of the 10 largest crypto assets. The token tracks CF Benchmarks’ Large Cap Index, covering about 95% of the crypto market, and is designed as an institutional-grade, fully collateralized, on-chain portfolio. LCAP is powered by Reserve Protocol’s onchain infrastructure mint/redeem, governance, composability) and built on Base. It will be tradable across both centralized and decentralized exchange venues, offering permissionless access to diversified crypto exposure.Ethereum Hits 6 Blobs Per BlockEthereum’s blob capacity has reached a new high of six blobs per block. The network currently has a target of 6 blobs per block and a maximum of 9 blobs per block. According to data analyst hildobby, Base and Worldcoin dominate actual blobspace usage, accounting for about two-thirds of it. Vitalik Buterin noted that the Fusaka upgrade, targeted for December 3, 2025, will address the current blob demand surge. Fusaka introduces Peer Data Availability Sampling (PeerDAS), allowing nodes to verify data availability by sampling small subsets rather than downloading entire blobs. It enables safer scaling, with throughput eventually increasing by up to 8x, from 6 to 48 blobs per block. After Fusaka, Blob Parameter Only (BPO) forks will gradually and automatically raise blob limits further.EF Launches Ethereum Everywhere TeamThe Ethereum Foundation launched the Ethereum Everywhere team to amplify and connect communities and events worldwide. The initiative focuses on strengthening Ethereum’s social layer, including the people, gatherings, and collaborations that sustain the ecosystem. The team will support grassroots groups, innovation hubs, meetups, and developer workshops.Other NewsTeku v25.9.3 releaseObol introduces Validator ManagerBALs for Proposer CommitmentsEuler supports mUSDYieldbasis opens for depositsFG Nexus buys 1,558 ETHInterview with Andrew KeysThat's it for today!
