Consequences of EIP-7623 for dapp builders

EIP-7623 proposes raising calldata costs for users who do not spend more than a certain threshold on EVM computation. Its stated goals include cutting the maximum possible block size from about 1.7 MB to 0.55 MB without affecting current throughput, reducing block size variance, and narrowing the gap between average and maximum block size. The proposal also aims to make room for a higher gas limit or blob count and to separate users who need calldata inside the EVM from those who use it purely for data availability, pushing the latter toward blobs. It does not cover consequences for dapp builders.
