PANews, July 8 news, according to the official blog of the Ethereum Foundation, all Ethereum execution clients now support pruning of historical data prior to the merge, which will reduce the disk space required for running nodes on the mainnet by 300-500 GB. This upgrade does not affect the normal operation of full nodes and validators, only providing savings in storage space. Users of archive nodes and application developers who need access to complete historical data will need to gradually turn to external historical data providers, with relevant resources available at https://eth-clients.github.io/history-endpoints/. This move is the first step in Ethereum's implementation of the 'expiration of historical data' mechanism defined in EIP-4444, aimed at optimizing network storage efficiency. More details can be found in the relevant EIP documentation.
