Ethereum co-founder Vitalik Buterin has recently revisited his vision for simplifying Ethereum node setup. This proposal aims to enhance network scalability without compromising on privacy, censorship resistance, or the ability for users to independently validate transactions. While currently a proposal, it has not yet been implemented on the mainnet.
In a research article dated May 19, 2025, Buterin emphasized the critical importance of personal node viability for network expansion. He pointed out that as Ethereum pursues higher throughput, an increase in Layer 1 capacity, without adjustments to the foundational design, would inevitably lead to a heavier burden for running nodes.
The core of Buterin's proposal is to ensure Ethereum remains friendly to users running their own nodes, even as the network's data processing capacity significantly increases in the future. He believes this goal will become even more crucial when the L1 Gas Limit expands by 10 to 100 times.
The rationale behind this move is rooted in decentralization and user control. Operating a local node allows users to query blockchain data directly, freeing them from reliance on external RPC providers and mitigating risks associated with request logging, access restrictions, or single points of failure.
However, the implementation of this proposal still faces hurdles. Currently, it remains a roadmap concept, and any user-level benefits will depend on subsequent engineering development and broad adoption by the Ethereum community.
Potential Impact of "Partially Stateless Nodes"
The central concept Buterin is proposing is a new type of node: the "partially stateless node." These nodes would continue to validate blocks but would only store a subset of the Ethereum state chosen by the user, rather than the entire dataset.
Under this model, users could decide what content to store locally, such as their most frequently used accounts, tokens, or applications. Nodes would then only respond to RPC requests related to these selected subsets, while still being capable of broader validation across the entire chain.
Buterin stated, "This is our new idea that is crucial for allowing personal nodes to run when L1 Gas Limit grows by 10x to 100x."
Furthermore, he linked this proposal to both short-term and medium-term roadmaps. In the short term, he mentioned EIP-4444, describing it as a step towards the eventual goal of each node storing only about 36 days of historical data.
In the longer term, he connected this design to stateless validation, where nodes validate blocks without locally storing all persistent state. Partially stateless nodes would represent a middle ground between the current resource-intensive full nodes and the more ambitious stateless model.
Pros and Cons of Simplifying Ethereum Node Setup
Proponents argue that simplified node setup promises to uphold Ethereum's core commitments as the network scales. Reduced storage requirements and a smaller local state footprint would make personal validation a more realistic option for users who prioritize privacy and self-custodied infrastructure.
Buterin directly addressed the privacy advantages, writing that such nodes "will provide the benefits of direct local access to the state that the user cares about," while guaranteeing complete privacy for access to that state.
Objections primarily center on complexity and timing. Implementing the proposal involves overcoming technical challenges and requires significant time for development and integration into the existing ecosystem.
