As we now have the Dencun upgrade live, we are able to use monitoring tools to check the network health. Initial monitoring indicates that we have a stable network with the current gas target and the re-org rate is trending downwards. Additionally, analysis on messages in gossipsub indicate that the inclusion of `IDONTWANT` messages could bring us a significant bandwidth savings. This allows us to consider starting a series of big block and blob tests to determine the theoretical headroom we currently have. The EIP specifies a proposed new blob gas target and limit based on the series of tests.

Additional EIPs such as [EIP-7623](./eip-7623.md) proposes a calldata cost increase which would significantly lower the worst case base block size, thus creating more headroom for a potential blob throughput increase.

This EIP aims to increase the throughput short term to provide some scaling until future solutions are deployed. In order to alleviate valid concerns about solo-stakers, approaches such as the inclusion of a flag indicating the max blobs per block for locally built blocks could be considered.
