## Summary

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.

EIP-7623: Increase Calldata Cost

By increasing the calldata cost for users that do not spend more than a certain threshold on EVM computation we can achieve the following:

Reduce maximum possible blocksize from ~1.7 MB to 0.55 MB without effects on current throughput.

Reduce block size variance

Reduce inefficienty from big gap between avg. block size and max. possible block size.

Make room for raising gas limit and/or blob count

Differentiate between users that need calldata inside the EMV vs pure DA.

This is achieved by increasing cost for DA users (who can move towards using blobs).
