Toni Wahrst ä tter, an Ethereum researcher at the Golden Financial News, has released a research report on EIP-7623, which aims to increase the gas cost of calldata used for data availability purposes in Ethereum transactions. By setting the benchmark gas price for non-zero bytes in calldata to 48 and zero bytes to 12, EIP-7623 aims to reduce the maximum block size from 3.5 MiB to approximately 1.9 MiB.
