Nethermind Lead: Version 1.3.1 is planned to remove Ethereum mainnet history before the merge on May 1st.

BlockBeats News, March 16th, Marek Moraczyński, lead of the Ethereum client Nethermind, published an article on the X platform stating that over 80% of Ethereum full nodes' disk space is occupied by historical records, which are not needed to validate new blocks. In the new version 1.3.1, Nethermind is prepared to perform a deletion of historical records before the merge via an ERA file. All teams have agreed to execute this operation on May 1st. If all blocks and receipts are deleted, retaining only the data necessary to validate the newest blocks, the disk space required for a full node will be less than 200 GB.
