Ethereum developers are advancing the Fusaka upgrade, scheduled for late November or early December following final testnet validation. This major network enhancement combines simultaneous improvements to Ethereum's consensus and execution layers.
The Fusaka upgrade introduces 12 Ethereum Improvement Proposals (EIPs) designed to significantly improve blockchain scalability and efficiency. Core feature EIP-7594 (PeerDAS) enables validators to sample data rather than downloading entire blobs, dramatically reducing bandwidth and storage requirements.
This technological advancement promises substantial benefits for Layer 2 rollups, potentially driving down transaction costs while increasing network throughput. New validators and smaller operators stand to gain the most, as node operation becomes more accessible and cost-effective.
Leading asset manager VanEck confirms Fusaka's importance for institutional adoption, noting reduced infrastructure costs for full node operators and strengthened ETH's position as a primary settlement asset. The upgrade also enhances Ethereum's compatibility with enterprise security standards and development frameworks.
Following successful October testnet deployments, Fusaka continues Ethereum's aggressive upgrade schedule, setting the foundation for the planned 2026 Glamsterdam hard fork focused on enhanced security through proposer-builder separation.
