Nethermind, the head of the Ethereum client: plans to remove historical records prior to the Ethereum merge in version 1.3.1

ChainCatcher message, according to Marek Moraczyński, head of the Ethereum client Nethermind, who posted on the X platform, over 80% of the disk space of Ethereum full nodes is occupied by historical records. Therefore, there is no need for data to validate new blocks. In the new version 1.3.1, Nethermind is ready to delete pre-merge historical records through ERA files, and all teams have agreed to carry out the relevant operations on May 1. If all blocks and all receipts are deleted and only the data required to validate the latest block is retained, the capacity of full nodes will be less than 200 GB.
