At Korea Blockchain Week KBW2023, Vitalik Buterin delivered a keynote speech saying that clients have to store more and more things.
The first solution is to stop storing historical data, that is, adopt EIP-444 (enforce bound historical data in the client), the second solution is to transfer state storage responsibility to dedicated nodes, and the third solution is to transfer The old object is moved out of state.
EIP-444 means that the client must stop providing historical headers, bodies, and receipts on the p2p layer for more than one year, and the client can delete (prune) these historical data locally.
