The rollout marks the second phase of Ethereum’s three-step roadmap, testing higher gas limits and the new PeerDAS data-sampling system. Ethereum’s Fusaka upgrade has been activated on the Sepolia testnet, marking the next major step in the network’s ongoing push to improve scalability and performance. The upgrade marks the second phase of a three-step rollout under Ethereum’s Fusaka roadmap, following the Holesky testnet activation on Oct. 1. The Sepolia deployment focuses on stress testing the network’s new data-availability system and higher block gas limit before developers push the code to the final Hoodi testnet later this month. Fusaka’s rollout is introducing a suite of performance and consensus improvements. The full upgrade aims to increase Ethereum’s block gas limit to 60 million, allowing blocks to process more transactions and complex smart-contract activity while testing whether nodes can maintain stability at higher capacity.

The Kingdom of Bhutan has tapped Ethereum to store the national identities of its roughly 800,000 citizens, leveraging the network’s immutability and decentralization. The South Asian nation of Bhutan is migrating its self-sovereign ID system to Ethereum from Polygon, allowing its nearly 800,000 residents to verify their identities and access government services. The integration with Ethereum has been completed, while the migration of all resident credentials is expected to finish by the first quarter of 2026, according to Ethereum Foundation President Aya Miyaguchi, who joined Ethereum co-founder Vitalik Buterin at the launch ceremony with Bhutan’s prime minister, Tshering Tobgay, and crown prince, Jigme Namgyel Wangchuk. “It’s deeply inspiring to see a nation commit to empowering its citizens with self-sovereign identity,” Miyaguchi posted to X on Monday, adding that the Ethereum integration was a world-first.

Ethereum layer-2 tokens outperformed the market, with Mantle surging 31%, driven by Bybit integration and increasing adoption across scaling solutions. Ethereum scaling tokens outperformed most of the cryptocurrency market after the weekend crash, signaling stronger price resilience among layer-2 (L2) projects built on the world’s largest smart contract network. Ethereum layer-2 scaling solution Mantle (MNT) had a 31% rebound on Monday, becoming the third-biggest gainer among the 100 largest cryptocurrencies tracked by CoinMarketCap. The Arbitrum (ARB) and Immutable (IMX) tokens also registered double-digit gains, while the Polygon (POL) token had an 8% rebound in the 24 hours up to the time of writing. Read more
Ethereum devs have introduced Kohaku to enhance wallet privacy and security with modular tools, zero-knowledge recovery options and decentralized transaction handling. Ethereum developers unveiled Kohaku, a roadmap that aims to improve wallet privacy and security through a modular framework designed for developers and advanced users. The project, announced in a Thursday blog post by Ethereum Foundation coordinator Nicolas Consigny, outlines plans to build a set of privacy and security primitives for the Ethereum ecosystem. At its core, Kohaku aims to create a software development kit (SDK) for building secure wallet functions, and a reference wallet that demonstrates how these tools work in practice. The first version will come as a browser extension based on the Ambire wallet, designed for advanced users who want more control and privacy. Read more
Bit Digital purchased 31,057 ETH worth $140 million, bringing its total holdings to over 150,000 ETH and making it the sixth-largest Ethereum treasury. Bit Digital expanded its Ether holdings to more than 150,000 ETH after purchasing 31,057 ETH valued at about $140 million using proceeds from a $150 million convertible notes sale. The deal, which included full exercise of underwriters’ options, positions the firm as the sixth-largest Ether (ETH) treasury among public companies, according to data from StrategicETHReserve.xyz. “This purchase demonstrates our commitment to building shareholder value by financing ETH accumulation on terms that are accretive to NAV per share,” said Sam Tabar, CEO of Bit Digital. “We view ETH as foundational to digital financial infrastructure and believe current levels provide a compelling long-term entry point,” Tabar added.
