Taiko is set to launch its 'Shasta' upgrade, which promises to significantly reduce rollup costs. The upgrade will decrease the cost of block proposing from a maximum of 1,000,000 gas to approximately 45,000 gas, marking a reduction of about 22 times. Additionally, the cost of proving will be lowered from 500,000 gas to around 280,000 gas, an improvement of approximately 8 times. This development is expected to enhance the efficiency and cost-effectiveness of Taiko's blockchain operations.
