The post Ethereum’s Fusaka Update Set to Boost Scalability with Mainnet Launch appeared on BitcoinEthereumNews.com.

TLDR The Fusaka update will activate on Ethereum’s mainnet on December 3rd, 2025, following a testnet rollout starting October 1st, 2025. The update will introduce a phased blob capacity expansion to improve data handling and Layer 2 rollup scalability. PeerDAS implementation through EIP-7594 will reduce bandwidth and storage requirements for validator nodes. The upgrade will create predictable transaction costs for data-heavy applications through bounded base fees for blob transactions. Fusaka focuses on enhancing Ethereum’s scalability, node efficiency, and data availability rather than adding user-facing features. Ethereum’s highly anticipated Fusaka update will activate on the mainnet on December 3rd, 2025. The upgrade follows a testnet rollout starting on October 1st, 2025, with Holesky leading the way. Developers have confirmed that Fusaka will implement significant improvements in scalability, node efficiency, and data availability. Phased Blob Capacity Expansion Through Fusaka Update The Fusaka update will prioritize backend protocol improvements. It introduces a phased blob capacity expansion with Blob Parameter Only (BPO) forks. The first BPO fork will increase capacity to 10/15 blobs, activating December 17, 2025. A second BPO fork will follow on January 7, 2026, further expanding capacity to 14/21 blobs. Ethereum developers emphasized that Fusaka will enhance the network’s data handling capacity. The increase in blob capacity will improve Layer 2 rollup scalability. Christine Kim, an Ethereum developer, stated that the phased approach offers greater flexibility for expanding blob limits. The Fusaka update is designed to support higher transaction volumes. It reduces bandwidth and storage demands, making Ethereum more efficient. This will enable Ethereum to handle more transactions without compromising security or decentralization. Improved Efficiency with PeerDAS and EIP-7594 in Fusaka Update Another crucial aspect of the Fusaka update is the introduction of PeerDAS through EIP-7594. This innovation allows validator nodes to verify data by sampling small pieces instead of downloading…
