Ethereum News Today: Ethereum's Fusaka Fork Tackles Trilemma with Scalability Breakthrough

Ethereum's Fusaka fork, a pivotal upgrade aimed at enhancing scalability and efficiency, is set for mainnet deployment on December 3 after successfully completing its final testnet phase on Hoodi. The upgrade introduces several Ethereum Improvement Proposals (EIPs), including PeerDAS (EIP-7594), which allows validators to sample smaller data pieces from layer-2 networks, improving node efficiency. Additional EIPs, such as EIP-7825 and EIP-7935, aim to increase gas limits and optimize parallel execution of smart contracts, further bolstering Ethereum's capacity to handle multiple transactions simultaneously.

The Fusaka upgrade is a cornerstone of Ethereum's "Surge" roadmap, addressing the blockchain trilemma's scalability challenge without compromising decentralization or security. Vitalik Buterin, co-founder of Ethereum, has highlighted PeerDAS as "the key to layer-2 scaling," emphasizing its role in enabling near-zero-cost transactions on layer-2 solutions. The update also builds on the Dencun upgrade's blob storage innovation, which temporarily stores layer-2 data to reduce fees. By expanding blob capacity, Fusaka is expected to lower costs for users and developers while enhancing data availability for layer-2 networks, according to a Yahoo Finance report.

The technical milestone comes amid a period of renewed institutional interest in Ethereum. The network saw $134 million in inflows into spot ETFs this month, reflecting growing adoption by corporate treasuries and institutional investors. Ethereum's price has also surged to an all-time high in 2025, driven by regulatory clarity and the approval of ETH ETF staking in 2025. Meanwhile, according to a Yahoo Finance analysis, treasury firms like Tom Lee's Bitmine have outpaced Bitcoin counterparts in Ethereum supply dominance, holding 3.2 million ETH as of October 23.

Despite the optimism, the Ethereum Foundation has faced internal challenges, with several key contributors recently departing and criticizing the network's direction. Nethermind, a prominent validator client, celebrated the testnet's success on X, calling it "another key milestone on the road to Fusaka." The upgrade's three-stage rollout will begin with the mainnet launch, followed by a blob capacity increase and a second hard fork to finalize the changes.

Post-Fusaka, attention will shift to the Glamsterdam upgrade, also part of the Surge roadmap, which aims to further refine Ethereum's scalability. The network's progress underscores its position as a leader in blockchain innovation, even as competitors like Solana and Sui focus on speed and throughput. For now, Ethereum's strategic focus remains on balancing security, decentralization, and scalability—a vision that Fusaka is designed to advance.
