Ethereum's Fusaka upgrade has successfully passed the Holesky testnet and is now progressing to the Sepolia and Hoodi testnets, with a mainnet deployment anticipated in early December. The upgrade will increase block gas limits from approximately 45 million to 150 million, enhancing throughput and reducing Layer-2 transaction costs. Additionally, it allows nodes to sample blob data, minimizing storage and bandwidth needs, which is crucial for Ethereum's scalability and future tokenization applications. Following the announcement, Ethereum experienced a short-term price increase of about 5%, while ETH Open Interest rose by approximately 4% within 24 hours, reflecting positive market sentiment towards the upgrade.
