Ethereum EIP-12188 Proposes Reducing Consensus Layer Block Retention Window, Gains Developer Support

BlockBeats News, August 18th, Ethereum developer kevaundray submitted EIP-12188 proposal on GitHub, suggesting a reduction in the Consensus Layer (CL) block retention window to alleviate node storage pressure. The proposal is currently in the public review stage and has received support from some Ethereum client developers.

Developer dapplion expressed support for the idea, while Lighthouse client contributor michaelsproul believes that this adjustment will not cause significant issues for Lighthouse operation. The proposal indicates that as Ethereum's historical data requirements change, reducing the Consensus Layer's historical block retention time can optimize node resource usage.

During the discussion, it was mentioned that Historical Data Pruning in the Execution Layer (EL) may impact some long-running nodes providing old block data. However, developers believe this will not threaten network security or disrupt node operation. Currently, EIP-12188 has not been merged and still requires further review and community discussion.
