[Ethereum's Next Hard Fork Upgrade 'Fusaka' Successfully Deployed on Holesky Testnet] According to Golden Finance, Ethereum's next hard fork upgrade 'Fusaka' has been successfully deployed and finalized earlier on the Holesky testnet, marking a critical first step toward its launch on the mainnet. The Fusaka upgrade aims to reduce operational costs on Ethereum, particularly benefiting institutional users and Layer 2 networks. One of its key features is PeerDAS, which will help lower costs for L2 and validators by optimizing data validation methods. According to the plan, Fusaka will undergo two additional testnet runs on October 14 and October 28. Once these tests are fully completed, Ethereum core developers will finalize the specific date for Fusaka's mainnet launch.
