Ethereum has successfully completed the final test of its Fusaka upgrade on the Holesky testnet, marking the last of three test runs before the upgrade's mainnet deployment. The Fusaka upgrade is designed to enhance scalability and reduce costs by allowing validators to process data segments instead of full blobs through PeerDAS technology. Developers are in the process of finalizing the mainnet launch date, with potential deployment as early as November 28, and discussions for a December 3 release ongoing. Meanwhile, Ethereum's next hard fork, Glamsterdam, is already under development, signaling continued progress in the network's evolution.
