The Prysm consensus layer client experienced a configuration mismatch that impacted Prysm validator participation rates following the Fusaka upgrade. The Prysm team provided a workaround, urging impacted node operators to add the --disable-last-epoch-targets validator flag to their Beacon node. The fix is compatible with client version v7.0.0 and does not require a full Beacon node update. Prysm is the second-largest Ethereum consensus layer client with a 17.49% market share, according to clientdiversity.org. Ethereum's multi-client architecture prevented a single point of failure, ensuring the network continued block production.
Etherealize, Nethermind, and L2Beat published a joint report analyzing Ethereum's L2 ecosystem and its role in the institutional adoption of blockchain for financial infrastructure. The report highlights Ethereum and its L2 ecosystem as the foundation for the global economy’s shift onto onchain rails. The report notes that the shift is being driven by the maturity of the market and increasing regulatory clarity from frameworks like MICA, GENIUS, and CLARITY Acts. L2s offer strategic advantages for institutions, including lower transaction costs, high throughput, and custom controls. L2s can also enable regulatory alignment by using Zero-Knowledge proofs for confidential compliance.
Global asset manager WisdomTree launched the WisdomTree Physical Lido Staked ETH ETP (LIST), the first European Exchange-Traded Product (ETP) to exclusively hold Lido’s stETH. LIST offers institutional investors exposure to staked ETH and onchain staking rewards through a regulated format. The ETP features a fully staked design, which uses stETH's deep liquidity to process creations and redemptions through secondary markets while avoiding the traditional unstaking buffers and validator withdrawal queues. LIST has begun trading with approximately $50 million in assets under management.
ZKsync announced that its Interop solution now allows any chain built with the ZK Stack to natively access the full liquidity of Ethereum L1 DeFi without suffering from fragmented liquidity or slow bridging speed. The ZKsync interop protocol handles the complex mechanics of L2 to L1 interactions, abstracting the process from the user. Users on a ZK Chain can deposit into Aave and borrow assets on Ethereum L1 while remaining entirely on L2. Institutions can now leverage Prividiums, private ZK L2s, to access public L1 market liquidity while maintaining their own governance, privacy, and execution environment.

The Fusaka upgrade successfully activated on the Ethereum mainnet at slot 13,164,544. The fork finalized within 15 minutes of activation. Fusaka brings 13 EIPs, delivering improvements in blob scaling, performance, and user experience. The headliner feature, Peer Data Availability Sampling (DAS), enables higher blob throughput, reducing costs for L2s. Blob Parameter Only forks are scheduled to further expand blob capacity by gradually increasing per-block blob limits. Fusaka marks Ethereum’s 17th upgrade, and the second upgrade to activate this year. Ethereum developers are now working on Glamsterdam, the next upgrade featuring BALs and ePBS, scheduled for 2026.
Linea announced that its EVM-equivalent ZK rollup upgraded to Fusaka simultaneously with Ethereum mainnet for the first time. Linea had previously activated four Ethereum upgrades (Paris, Shanghai, Cancun, and Prague) since its launch. The simultaneous activation brings Ethereum's latest EIPs to Linea in real-time. Linea users and dapps have access to the newest EVM features, including EIP-7951, which enables native passkey support while lowering verification costs. Linea also implemented zkASM, a high-level "source language" that generalizes EVM constraint logic and compiles directly into circuits.
The Protocol Guild, a collective supporting Ethereum core protocol contributors, released its Q4 2025 quarterly audit of funded members. The Guild's membership has grown to 184 active core contributors, reflecting a net increase of 8 members from the prior quarter. The guild added 23 new members across teams like Lighthouse, Prysm, and the new zkEVM Working Group. 14 members were also graduated to alumni status, including figures like Dankrad Feist and Davide Crapis. The changes were processed onchain for the first time using new Agora-based DAO contracts. The Protocol Guild has allocated over $33 million to Ethereum core developers since its launch in May 2022.
Shutter Network and Primev are launching a threshold encrypted mempool aimed at protecting users from malicious MEV attacks. The solution uses Shutter's threshold encryption to keep transactions unreadable until their execution order is fixed, combined with Primev's mev-commit infrastructure. It also uses economic enforcement to ensure builders commit blindly and honestly. Users can access the MEV protection by using a custom FastRPC endpoint hosted by Primev. The solution is targeted for a mainnet launch by Q1 2026.

The Fusaka upgrade is scheduled to go live on Ethereum mainnet on December 3, 2025, at 21:49:11 UTC. Node operators must update both their Execution and Consensus Layer clients to the latest versions before activation. Fusaka brings 13 EIPs with improvements to scaling, performance, and developer and user experience. The Ethstaker community will be hosting a watch party on the Ethereum YouTube channel starting 30 minutes before the scheduled fork activation. The Nethermind team is also hosting a separate 2-hour livestream featuring guest speakers across core clients and research teams, including EF Co-ED Tomasz Stanczak.
Optimism activated the Jovian Hard Fork on the Superchain, introducing improvements to fee mechanisms, maintenance updates to the fault-proof Cannon VM, and new data-availability protections. The upgrade allows chains to optionally set a minimum base fee to shorten priority-fee auctions. It also introduces an in-protocol limit on Data Availability footprint to reduce DA spam and fee-auction manipulation. The upgrade is now live for Superchain members, including OP, Base, Soneium, Ink, Unichain, Metal, Mode, and Zora.
Uniswap integrated Revolut, Europe’s largest neobank, into the Uniswap Web App and Wallet, enabling users to buy crypto directly using their Revolut balance, Revolut Pay, cards, or mobile wallets. Revolut offers 0% fees when using Revolut Pay, requires no additional identity checks for existing users, and offers over a dozen fiat currencies. The integration expands Uniswap’s onramp options, including Robinhood, Transak, and MoonPay, and supports 40+ tokens. Revolut currently only supports onramping, with plans to enable offramping in the future.
MetaMask introduced Transaction Shield, a new paid subscription service that provides users with up to $10,000 in loss protection on certain onchain transactions. The subscription also includes priority access to MetaMask support. The protection applies to DeFi swaps and lending on verified apps, NFT mints and marketplace sales, and airdrop claims from verified smart contracts. The insurance product does not cover losses from compromised wallets or protocol-level exploits. Transaction Shield builds on MetaMask’s existing safety infrastructure, including automated transaction simulations and contract risk checks, and is currently available on the MetaMask browser extension.
