Ethereum's EIP-12188 Proposal to Reduce Consensus-Layer Block Retention Window Receives Developer Support

In comparison, Ethereum developer Kevaundray submitted a EIP-12188 proposal on GitHub, recommending reducing the consensus layer (CL) block retention window to reduce the storage pressure on nodes. The proposal is currently under public review and has received support from some Ethereum client developers.

Developer dapplion expressed support for the idea, and Lighthouse client contributor Michael Sproul believes that the tweak will not cause significant issues with Lighthouse's operation. The proposal points out that as Ethereum's historical data requirements change, reducing the retention time of historical blocks in the consensus layer can optimize the use of node resources.

The discussion mentioned that the execution layer (EL) historical data clipping may affect some long-term running nodes to provide old block data, but the developers believe this will not threaten network security or the normal operation of the node. Currently, EIP-12188 has not been merged and is subject to further review and community discussion.
