The Fusaka upgrade activated on December 4th for Ethereum focuses on three core benefits: network performance, ecosystem development, and market confidence.

1. Significantly enhance network throughput and efficiency: The core introduces PeerDAS technology, allowing nodes to store only about one-eighth of the binary large object (blob) data to verify availability, theoretically increasing blob throughput by 8 times; subsequently, there will be phased relaxation of block storage unit limits, and the block gas limit will also be increased by 5 times, greatly alleviating network congestion.

2. Reduce transaction costs and optimize experience: The L2 network relies on blobs to submit transaction data; after the upgrade, Rollup transaction costs are expected to decrease by 70%, and EIP - 7917 introduces a pre-confirmation feature that can reduce user transaction delays and confirmation uncertainties; at the same time, the newly added technical features also enhance hardware device compatibility and optimize wallet interaction experiences.

3. Support deeper participation from the ecosystem and institutions: The upgrade significantly improves the accessibility of L2 network data and operational efficiency, which can promote the implementation of more decentralized applications; it addresses Ethereum's scalability bottleneck, and with reduced gas fees, it will further attract institutional participation. Previously, many companies, including BlackRock, have deployed applications on Ethereum and its L2 layer, and this trend will accelerate after the upgrade.

4. Strengthen network security: It includes multiple adjustments to defend against DoS attacks, such as limiting transaction gas limits, setting execution layer block sizes, etc., and also identifies code vulnerabilities through audit competitions, reducing network instability risks and providing more reliable guarantees for ecosystem activities and fund security.
