According to a research post published by PANews on May 19, Vitalik Buterin proposed adding an adjustment of "biased towards local nodes" to the Ethereum expansion roadmap to mitigate the impact of increasing the upper limit of Gas on individuals running full nodes. Vitalik pointed out that the important value of personal nodes lies not only in on-chain verification, but also in the privacy and anti-censorship requirements of reading chain data as a local RPC. His suggestions include: accelerating the full implementation of EIP-4444, building decentralized historical data storage, adjusting the Gas mechanism to increase the storage cost of new states, and proposing a new "partial stateless node" model that allows users to save key states on demand, taking into account storage efficiency and local privacy.
