The latest important upgrade of Ethereum, Fusaka, has been successfully deployed on the Holesky testnet, marking a significant step for Ethereum in improving network performance and scalability.

The core of the Fusaka upgrade lies in the introduction of PeerDAS (Peer Data Availability Sampling) technology. This innovation greatly simplifies the verification process. Traditionally, verifying nodes need to download the entire data block for verification, while PeerDAS allows nodes to efficiently confirm data integrity through random sampling checks. This technological breakthrough will significantly reduce the cost of submitting data from Layer 2 solutions to the Ethereum mainnet, promising users lower transaction fees on Layer 2 networks such as Arbitrum and Optimism.

This upgrade not only optimizes network performance but also lowers the threshold for participating in Ethereum network validation. In the past, running a validation node required high-performance hardware and large bandwidth, but now even computers with ordinary configurations can handle it, which will undoubtedly promote the decentralization of the network. For institutional users, the reduction in operational costs makes Ethereum-based blockchain solutions more attractive.

The successful deployment on the Holesky testnet not only confirms the feasibility of the technical solution but also highlights the outstanding execution capabilities of the Ethereum development team. Next, the Ethereum community will closely monitor two follow-up tests in mid-October. If these tests are also successfully completed, the Fusaka upgrade on the Ethereum mainnet will be imminent.

This upgrade reflects Ethereum's commitment to continuous innovation and optimization, aiming to create a more efficient, economical, and decentralized blockchain ecosystem. With the advancement of Fusaka, we have reason to expect that the Ethereum network will provide more robust infrastructure support for decentralized applications and the Web3 ecosystem in the future.
