Today marks the activation of Ethereum’s Fusaka hard fork, a significant upgrade designed to enhance data accessibility and network capacity. The update follows the Pectra upgrade, which went live earlier this year. 🤯
This latest modification utilizes Peer Data Availability Sampling (PeerDAS) to reduce bandwidth requirements for validators. This feature unlocks up to 8 times faster data throughput for Ethereum’s Layer 2 networks, leading to cheaper transaction fees and greater development potential. 🚀
The Fusaka hard fork also introduces Blob Parameter Only (BPO) forks, which enhance the network’s capacity by adjusting the blob target, maximum, and fee update fraction. Additionally, Ethereum’s block gas limit is increased from 30 million to 150 million units, providing more room for transactions within each block.
The upgrade will be rolled out on the mainnet after successful testnet deployments on Hoodi, Sepolia, and Holesky. This represents a major step in Ethereum’s modular roadmap, aiming for improved scalability without compromising decentralization. 🗺️
Layer 2 networks such as Arbitrum, Optimism, and Base are expected to integrate PeerDAS in the coming weeks, enabling them to post more data efficiently while lowering transaction costs. This will further enhance user experience and unlock new possibilities for decentralized applications.
Ethereum’s roadmap includes Osaka, scheduled for 2026, which introduces blob streaming and stateless validator clients to reduce costs and enhance decentralization.
