According to online reports, Ethereum core developers Anders Elowsson and Vitalik Buterin jointly proposed a new proposal EIP-0000, aiming to achieve a unified multi-dimensional fee market mechanism. The proposal proposes allowing users to set a single maximum fee cap (max_fee) for multiple resource types to improve capital efficiency. This mechanism will make max_fee interchangeable between different resource types and is expected to simplify the management process of current multiple independent fee markets such as blobs, calldata, and gas. The proposal also provides an expanded foundation for integrating more resource types in the future.
