Ethereum to Deploy Fusaka on Dec 3, 2025 — 12 EIPs to Boost Layer‑2 Throughput
Ethereum developers have scheduled the Fusaka hard fork for mainnet on December 3, 2025 (slot 13,164,544). Fusaka bundles 12 EIPs that coordinate changes across the consensus and execution layers to improve interoperability with Layer‑2 networks, speed cross‑layer transactions, raise Layer‑2 throughput and reduce gas/execution costs. A key feature, PeerDAS, lets validators verify portions of data instead of whole blobs, cutting bandwidth and validation costs and benefiting validators, rollups and users. The upgrade has already deployed successfully on the Hoodi testnet and was confirmed at the All Core Developers Consensus Layer (ACDC) meeting. For traders, Fusaka targets higher Layer‑2 capacity and lower transaction costs for users, which may increase on‑chain activity and demand for ETH for gas over time. Monitor upgrade progress, testnet results and any client updates or replay protection guidance ahead of the December activation.
Bullish
Fusaka focuses on coordinated consensus and execution changes and includes features (notably PeerDAS) designed to reduce validation bandwidth and costs while increasing Layer‑2 throughput and cross‑layer transaction speed. For ETH price dynamics, this is generally bullish: improved Layer‑2 capacity and lower user costs tend to increase on‑chain usage and demand for gas, supporting longer‑term ETH utility. Short term, volatility around client updates, testnet feedback and any required node operator actions (client upgrades, replay protection) could cause transient sell‑pressure or uncertainty; however, the successful Hoodi testnet deployment and clear activation date reduce execution risk. Overall, enhancements that materially improve scalability and reduce costs historically correlate with increased network activity and positive sentiment for the native token, so the net impact on ETH is expected to be bullish — watch upgrade execution and Layer‑2 adoption metrics for confirmation.
