The article discusses the challenges brought by the ever-growing storage demand of Ethereum, particularly the inconsistency in storage behavior among full nodes. To solve this problem, the EIP-4444 and EIP-4844 standardized historical data deletion schemes are proposed. The article introduces the Ethereum Portal network and the EthStorage network as solutions, the former being a lightweight P2P network and the latter an incentivized modular storage network, both aiming to provide decentralized, Ethereum-aligned data storage and access. The article also proposes future development plans, including a decentralized Ethereum state network, proof of storage for dynamic-sized data, and decentralized access from browsers.
