What Actually Changed with the Ethereum Fusaka Upgrade

The Ethereum Fusaka upgrade is a hard fork focused on preparing the network for greater scale and efficiency, impacting data storage, transaction handling, and Rollup interaction. The most significant change is increased capacity, allowing blocks to hold more information, which eases pressure during high demand without instantly increasing speed. Fusaka specifically expands blob space for Rollups like Arbitrum and Optimism, aiming to lower transaction costs for users as these networks scale. Furthermore, the upgrade introduces PeerDAS, a system where nodes verify data by checking small, random samples instead of the entire load, significantly reducing bandwidth and storage requirements for validators, thereby boosting decentralization. It also raises the block gas limit for higher throughput and adds support for P-256 signatures, paving the way for future, more user-friendly wallet authentication methods like biometric login. Ultimately, Fusaka is a foundational upgrade that strengthens the network's structure to support future growth and adoption.
