Ethereum Introduces Blob Gas to Reduce Rollup Data Costs

Ethereum's latest upgrade introduced a new type of gas called blob gas, designed to make it cheaper for Layer 2 networks to publish large amounts of transaction data.

Blob gas is separate from regular Ethereum gas and is used specifically to price the storage and availability of temporary blob data.

The main purpose of blob gas is to reduce the cost of publishing rollup data, which can be expensive using traditional calldata. With blob gas, Layer 2 networks such as Base, Arbitrum, and Optimism can publish transaction data at a lower cost.
