The Ethereum Foundation has recently undergone an internal transformation, injecting new momentum into network development by adjusting its personnel structure and improving work efficiency. The effects of this change have already begun to show, with the next upgrade named Fusaka scheduled for this November following the Pectra upgrade. Moreover, the foundation plans to finalize the specifics of the next upgrade, Glamsterdam, in August of this year. This efficient work pace stands in stark contrast to the previous one, highlighting the necessity and importance of the reform.

The Fusaka upgrade includes 13 Ethereum Improvement Proposals (EIPs), focusing primarily on two core objectives: enhancing support and control for Layer 2 scaling solutions (L2), while improving the stability of the mainnet. Let's delve into several key proposals:

EIP-7594 is an optimization built on top of EIP-4844 introduced in the previous Cancun upgrade. By implementing a sampling validation mechanism for blob data availability, nodes do not need to download all blob data but only process a portion of samples, significantly enhancing L2 scalability and reducing storage pressure.

EIP-7892 introduces a hard fork mechanism for blob capacity expansion, making blob-based upgrades more flexible and further enhancing the scalability potential of L2.

EIP-7918 has adjusted the calculation of blob fees. With the booming development of the L2 ecosystem, there may be concerns about L2 "siphoning" L1. To address this potential issue, the proposal sets a minimum threshold for blob base fees and ties it to execution fees, ensuring that the L1 network can benefit reasonably.

EIP-7825 limits the maximum Gas usage for a single transaction to 16,777,216 (2^24). This measure aims to reduce the risk of Denial of Service (DoS) attacks caused by high Gas transactions, enhance the security of the network, and promote a fairer allocation of Gas resources for transactions within blocks.

EIP-7934 sets the Ethereum block size limit to 10MiB, which helps prevent network instability and potential DoS attacks caused by large blocks, thereby maintaining the healthy operation of the entire network.

These upcoming upgrades not only reflect the technical strength of the Ethereum team but also demonstrate their thoughtful consideration for the long-term development of the network. By continually optimizing and improving, Ethereum is preparing for future large-scale applications and broader adoption.
