According to Vitalik Buterin, a co-founder of Ethereum, on the X platform, the Ethereum client Geth v.1.16.0 has released a PBSS based archive node, which means users can have a Geth archive node in approximately 1.9 TB of space (previously requiring over 20 TB of space capacity), and can also query historical status (such as the balance of block X), but currently cannot provide proof of historical status.
