EIP-4844

EIP-4844 introduces an independent blob data structure and a fee market for the Ethereum DA (Data Availability) layer, significantly reducing the cost of layer2 DA. It resolves the "0-1" problem in Ethereum's layer2-centric scaling roadmap.

EIP-4844 designs each blob to have a size of 128KB, with a maximum of 6 blobs supported per block and a target value of 3 blobs. If the number of blobs in a single block exceeds 3, the DA fees will increase exponentially. The Ethereum DA scalability designed by EIP-4844 is 32KB/s.
