Taiko's Shasta upgrade aims to cut rollup costs by up to 22x

Ethereum layer-2 project Taiko has announced plans to overhaul its rollup economic structure with its upcoming Shasta upgrade. The upgrade features a simplified design using only three core contracts: inbox, anchor, and signal service. With the implementation of Shasta, proposing costs are expected to decrease approximately 22-fold, from one million gas to 45,000 gas. Proving costs are also projected to fall from 500,000 gas to 280,000 gas. Taiko stated that the upgrade is currently undergoing internal testing and is scheduled for deployment on the Hoodi testnet within a few weeks. The mainnet launch is pending approval from the project's decentralized autonomous organization (DAO). The company anticipates that the Shasta upgrade will deliver significant improvements in decentralization, security, and cost-efficiency.
