TechFlow reported, according to Foresight News, that Vitalik Buterin delivered a keynote speech at Korea Blockchain Week KBW2023 stating that clients are forced to store an increasing amount of data.
-
The first solution is to stop storing historical data, namely adopting EIP-444 (bound historic data in execution clients);
-
The second solution is to transfer state storage responsibilities to dedicated nodes;
-
The third solution is to move old objects out of the state.
EIP-444 refers to clients ceasing to provide headers, bodies, and receipts older than one year over the p2p layer, allowing clients to locally delete (prune) this historical data.
Vitalik Buterin concluded that if we have statelessness and PBS, state expiry becomes low priority—even an 8TB state would be manageable. Ultimately, we do need to address the 20-byte address issue, whether for state expiry or long-term security considerations.
