Ethereum co-founder Vitalik Buterin has put forward a technical proposal aimed at making it significantly easier for individuals to run their own nodes on the network. In a pull request posted on a Saturday, Buterin suggested merging the two distinct backend programs—the consensus client (which interacts with the Beacon Chain for staking and consensus) and the execution client (which handles transactions and smart contracts)—into a single, unified code structure. This change is designed to simplify the complex setup process currently required for node operators.
Presently, running an Ethereum node, or validator, demands managing and synchronizing two separate software clients. This bifurcation adds layers of technical complexity, time commitment, and potential points of failure. Buterin argues this burden effectively outsources the network’s infrastructure to a small group of professional operators and third-party service providers, undermining the principle of broad decentralization.

“I feel like at every level, we have implicitly made this decision that running a node is this oh so scary DevOps task that it is ok to leave to professionals,” Buterin stated in a post on X. He challenged this norm directly: “It is not. We need to reverse this. Running your own Ethereum infrastructure should be the basic right of every individual and household. ‘The hardware requirement is high, therefore it’s okay for the DevOps skill and time requirements to also be high,’ is not an excuse.” He emphasized that even technically adept users with the necessary hardware often lack the time for intricate setup, concluding simply: “nodes should be easy.”
This technical complexity is a well-documented hurdle for Ethereum and similar smart contract platforms. The requirement for high-performance, specialized hardware and significant storage has contributed to centralization concerns, as fewer participants can afford or manage the operational overhead.
Addressing the Storage Bottleneck: Partially Stateless Nodes
The unification proposal is part of a broader, long-term effort to lower barriers to entry. In May 2025, Buterin previously introduced the concept of “partially stateless nodes.” This architecture allows node runners to operate without storing the entire historical blockchain state, keeping only the minimal data required for their specific tasks—like sending transactions or verifying blocks.

According to analysis from Go-Ethereum (Geth), the leading execution client, disk space is the primary bottleneck for node operators. Networks like Ethereum produce vast and ever-growing datasets, making full-node storage a continually escalating expense. Partially stateless nodes directly target this cost driver, potentially allowing participation with consumer-grade hardware.
Buterin has warned that a network reliant on a handful of large Remote Procedure Call (RPC) providers creates a central point of failure and censorship. “A market structure dominated by a few remote procedure call (RPC) providers is one that will face strong pressure to deplatform or censor users. Many RPC providers already exclude entire countries,” he noted, framing independent node operation as a critical defense for network neutrality and access.
Funding the Decentralization Mission
To support research and development into these and other infrastructure improvements, Buterin recently announced a significant personal commitment. In late January, he revealed he had set aside 16,384 Ether—then worth approximately $45 million—from his personal holdings. These funds are earmarked for advancing privacy-preserving technologies, open hardware initiatives, and the development of secure, verifiable software for the Ethereum ecosystem.
Buterin indicated the funds would be deployed gradually over the coming years. This coincides with a period he described as “mild austerity” for the Ethereum Foundation’s own budget, though he affirmed the Foundation would continue advancing its core technical roadmap. The personal fund serves as a targeted supplement to accelerate projects that enhance user sovereignty and network resilience.
