Vitalik Buterin floats 5 designs to decrease Ethereum max block size

Ethereum co-founder Vitalik Buterin and the Ethereum Foundation are considering at least five ways to reduce Ethereum’s maximum block size in hopes to optimize the blockchain for the "rollup-centric roadmap."
On Feb. 5, Buterin and Ethereum Foundation researcher Toni Wahrstätter said that with the focus on rollups in the medium and long term, it is argued that the way block space is used is not yet optimized — noting that effective block size has essentially doubled over the past 12 months.
“This might be a result of more and more rollups starting to use Ethereum for DA and trends like Inscriptions,” explained Buterin and Wahrstätter

The blog post discusses five different solutions — varying in complexity — to increase block gas limits and disincentivize the use of calldata, which could then reduce maximum block size and variance to make room for more data blobs in the future.
“By increasing the block gas limit and the price for nonzero calldata bytes, a smaller and less variable block size can be achieved, making space to add more blobs in the future.”
The Ethereum gas limit refers to the maximum amount of gas spent on executing transactions or smart contracts in each block. A limit is set to ensure that blocks are not too large, which would impact network performance and synchronization. Calldata, which consumes gas, increases the load on the network, so solutions are being sought to increase the gas limit without compromising security.
