According to Foresight News, Taiko, an Ethereum second-layer network based on zkRollup, has announced a successful upgrade to its mainnet protocol to v1.7.0. This update is expected to significantly reduce the Gas usage of the Rollup protocol on Ethereum. The upgrade is a significant step forward for the network, as it aims to improve efficiency and reduce costs for users. The reduction in Gas usage is particularly important, as it can lead to lower transaction fees and faster processing times. This is a crucial development for Ethereum, as it continues to face challenges with scalability and high transaction costs. The upgrade by Taiko could potentially alleviate some of these issues, making the Ethereum network more efficient and user-friendly.
