PANews reported on March 16 that Marek Moraczyński, head of the Ethereum client Nethermind, posted on the X platform that more than 80% of the Ethereum full node disk space is currently occupied by historical records. In the new version 1.3.1, Nethermind is ready to remove pre-merger historical records through ERA files, and all teams have agreed to perform relevant operations on May 1. If all blocks and all receipts are removed and only the data required to verify the latest block is retained, the full node capacity will be less than 200 GB.
