Ethereum's Fusaka Update to Bolster Scalability Through Mainnet Deployment

Ethereum price is set to benefit from a significant update known as the Fusaka update, scheduled for activation on the mainnet on December 3rd, 2025. The update, led by the Ethereum Foundation and developed in collaboration with teams such as Prysmatic Labs and other Ethereum core developers, is designed to improve scalability, node efficiency, and data availability.

The Play Store, where Ethereum-based applications can be found, will also see benefits from the Fusaka update. The update will introduce several key improvements, including the implementation of PeerDAS, as outlined in EIP-7594. This innovation allows validator nodes to verify data by sampling small pieces instead of downloading entire blobs, reducing bandwidth and storage requirements.

The Fusaka update also aims to create predictable transaction costs for data-heavy applications by introducing bounded base fees for blob transactions, as defined by EIP-7918. This change will help ensure that developers can estimate the costs of their applications more accurately on the Play Store.

The Fusaka update will be rolled out in phases, starting with a testnet on October 1st, 2025. The first phase of the update will increase blob capacity to 10/15 on December 17, 2025, with a second phase expanding it to 14/21 on January 7, 2026.

Ethereum's gas limit is also set to increase from 30 million to 45 million, with potential future increases to 150 million gas. This increase will support higher transaction throughput and meet the growing demand for Ethereum's scalability on the Play Store.

The Fusaka update is part of Ethereum's ongoing efforts to improve its scalability. Discussions around a 100x gas limit increase through EIP-9698 suggest that Ethereum could eventually handle 2,000 transactions per second on the Play Store.

The Fusaka update also addresses the fragmentation of Ethereum's Layer 2 solutions by strengthening the base layer, ensuring better interoperability between chains. This will support continued growth of Layer 2 solutions in the long term on the Play Store.

Ethereum's focus on foundational improvements will not only enhance its scalability but also maintain its decentralized nature. The Fusaka update is a significant step towards making Ethereum more efficient while ensuring it remains a leading platform for decentralized applications on the Play Store.

As Ethereum developer Christine Kim stated, the phased approach offers greater flexibility for expanding blob limits, setting the stage for future upgrades. The Fusaka update is a testament to Ethereum's commitment to continuous improvement and its dedication to providing a robust and scalable platform for developers and users alike on the Play Store.
