The Fusaka upgrade successfully activated on the Hoodi testnet, marking the third and final testnet to complete the upgrade. The milestone sets the stage for Fusaka on Ethereum mainnet, currently scheduled to occur on December 3, 2025, at 21:49:11 UTC. The Fusaka upgrade introduces 12 Ethereum Improvement Proposals (EIPs) that improve scalability, performance, and UX.  The upgrade’s headline feature is PeerDAS (EIP-7594), a standard that brings higher blob throughput, significantly reducing L2 transaction costs and enhancing scalability. After Fusaka, two Blob Parameter Only (BPO) forks are scheduled to gradually and automatically raise blob limits. Fusaka-ready client releases for mainnet will be available from all client teams by November 3rd.

ZisK, a high-performance zero-knowledge virtual machine (zkVM) stack designed for low-latency proof generation, reached a major milestone: real-time proving of Ethereum L1 blocks. The achievement comes with the release of ZisK v0.13, which enables continuous zk-proof generation with an average proof time of about 7.5 seconds, using a cluster of 24 NVIDIA RTX 5090 GPUs. ZisK leverages a distributed proof generation mechanism, where multiple workers cooperate as a unified system to construct each zk-proof. The system minimizes proof latency and maximizes throughput. ZisK is independently led by Jordi Baylina and remains fully open source under MIT/Apache-2.0 licences.

Ethereum Name Service (ENS), the leading protocol for converting complex blockchain addresses into human-readable names, introduced two new web apps: the ENS App and the ENS Explorer. The ENS App is a revamp of its domain register and manager. The ENS Explorer, built for developers, provides advanced ownership management, custom resolvers, data transparency, and detailed historical records. Both tools will launch alongside ENSv2, a major protocol upgrade that introduces a new registry, updated smart contracts, and the Namechain Layer 2 network focused on identity. Users can sign up for to participate in upcoming user testing during Devconnect in Buenos Aires.

Base announced plans to double the block gas limit on Base Chain from 75 to 150 Mgas/s by the end of 2025, as part of its broader scaling roadmap targeting 400–500 Mgas/s by early 2026. The L2 network is shifting focus from scaling the gas target to scaling the gas limit to safely increase capacity while maintaining sub-cent transaction fees. Base highlighted client execution speed as its main current bottleneck and has migrated from Geth to the Reth client. The network already achieved its first block sequenced by Reth.

• JPYC yen-backed stablecoin.

• Abstract enables 200ms block times.

• ETHZilla sells $40m ETH.

• SOON for fast propagation.

JPYC Inc., a Tokyo-based fintech firm, launched JPYC, Japan’s first regulated stablecoin pegged to the yen, now live on Ethereum, Polygon, and Avalanche. The stablecoin is fully backed by Japanese yen bank deposits and Japan Government Bonds (JGBs) in compliance with the country’s Payment Services Act. The stablecoin’s issuance is managed through JPYC EX, a dedicated platform that utilizes Japan’s “My Number” national ID system to ensure compliant transactions. JPYC is designed to support B2B payments, remittances, and DeFi applications, with an ambitious target of reaching ¥10 trillion in issuance within three years.

Abstract Chain, a consumer-focused Ethereum Layer 2, activated 200-millisecond block times, cutting latency by 5x from its previous one-second blocks. The upgrade delivers the speed necessary for real-time applications and seamless UX with one-click transactions. The feature is powered by a custom ZK proving and sequencing system that operates without Flashblocks preconfirmations. Launched in early 2025, Abstract is built on ZKsync’s ZK Stack and utilizes EigenDA for data availability. The network processes around 250,000 transactions daily and secures over $186 million in value.

ETHZilla Corporation, an Ethereum Digital Asset Treasury (DAT) company formerly known as 180 Life Sciences Corp, sold approximately 10,256 ETH from its treasury holdings to initiate a $40 million share buyback program. Since October 24, ETHZilla has repurchased approximately 600,000 shares for about $12 million under its broader $250 million buyback authorization. The company said the buyback aims to support shareholders, reduce shares available for short selling, and increase NAV per share, as its stock trades at a significant discount to NAV. Meanwhile, BitMine Immersion Technologies Inc. added 77,055 ETH to its treasury in the past week, bringing its holdings to 3.3 million ETH.

Gm frENS. We meet again on yet another Friday. Have a great weekend!

• Ledger Multisig charges a fee per tx.

• MegaETH introduces MEGA token.

• L2BEAT verifies Polygon zkProver integrity.

• Nethermind and Besu interop on BALs.

Ledger, a hardware wallet provider, is facing backlash over fees for its new Ledger Multisig product. Built on the open-source Safe protocol, Ledger Multisig enables users to sign transactions for Safe-based multisig wallets using Ledger hardware devices with Clear Signing, which verifies transaction details directly on the device. Initially marketed as a free feature, Ledger later clarified that it charges $10 per standard transfer for ETH sends and non-token actions like governance and 5 basis points on the value for ERC-20 token transfers, on top of network gas fees. Users can avoid the fees by using Safe’s native web app, which features software-based transaction simulations.

MegaETH, an Ethereum Layer-2 network featuring 10 ms block times and a 100,000 TPS architecture, introduced $MEGA, its native token used to power Sequencer Rotation and Proximity Markets. Sequencer Rotation ensures that only one sequencer is active at a time, rotating globally to follow active regions. Operators can stake $MEGA to compete for the active slot, which is selected based on stake size, performance history, and infrastructure quality. Proximity Markets allow apps and market participants to lock $MEGA and bid for sequencer-adjacent colocation space to access minimal latency and faster transaction confirmations. MegaETH is currently in a public testnet phase.

L2BEAT announced that it has successfully reproduced Polygon’s zkProver verifier keys, which are used to validate zero-knowledge proofs. Anyone can independently regenerate and confirm that the onchain verifier matches the published setup. The L2BEAT team verified that the regenerated keys match the deployed verifier contract, including hash and ABI consistency. The process strengthens the cryptographic integrity of Polygon’s ZK system, ensuring that proofs cannot be forged due to incorrect verifier keys.
