According to Foresight News, Ethereum core developer Tim Beiko recently summarized the latest Ethereum execution layer meeting, which included discussions on the devnet-8 status update and the implementation of EIP-7514 as part of the Dencun upgrade. EIP-7514 aims to limit the maximum validator growth rate from exponential to linear growth through the Epoch Churn Limit.
Regarding the devnet-8 status update, the network is being finalized, and many clients have released updates. Kurtosis testing for MEV/block building processes has already begun. Nethermind reported that their Blob transaction pool is now ready and has been deployed on all Dencun test nodes after testing on a single node for a few days. Geth's blob txn pool is also nearing completion.
Besu is conducting a thorough inspection of its transaction pool to limit the size of Blob and non-Blob transactions and is expected to release it in the next version. Prysm noted some delays when receiving blob sidecars, stating that they usually appear within about 500 milliseconds after a block (processing takes about 15 milliseconds). Prysm is investigating this issue and whether it may be caused by a race condition between blob and block imports.
Before the fork, there was a question about whether to allow support for blob txn in the memory pool, and the team agreed not to do so. The meeting also discussed whether to add a constant upper limit to the validator activation queue. This proposal was later officially named EIP-7514 and will be part of the Dencun upgrade. The EIP and related CL specification PR are expected to be updated in the coming days to reflect all these changes. Developers also reached a consensus to limit the Max Epoch Churn Limit to 8.
Another proposal discussed by the developers was to add an opcode to expose the basic blob fee in the EVM.
