Vitalik: On-chain only storing hashes still requires storing and updating data needed for proof verification

BlockBeats news, on May 18, Ethereum co-founder Vitalik Buterin commented on Ethereum's state storage issue, saying that even if users store data themselves, the blockchain only stores hashes, and transactions only include proofs, it is still necessary to store and update data used to verify proofs. Ultimately, this data is almost as large as the state itself. Vitalik noted that there are solutions to these issues, but they involve many components and require trade-offs compared to the current Ethereum.

Previously, DeFi content creator marilyn100x.eth pointed out that Ethereum faces a state storage problem, where developers pay a one-time fee to write data, but nodes bear long-term storage costs. However, EIP-8037 is not a time-weighted rent or continuous fee. Instead, it significantly increases the upfront gas costs for new contracts, accounts, and storage slots to control state growth during scaling.
