Vitalik Introduces New Node Architecture Proposal
Vitalik Buterin recently unveiled a new technical proposal aimed at simplifying Ethereum node operations. Published as a Pull Request, the proposal centers on merging the two core programs currently run separately into a unified backend architecture, making node deployment more straightforward.
At present, Ethereum nodes must run:
-
Consensus layer program
-
Execution layer program

These two systems must operate in sync and exchange data to keep the network running.
Complexity of the Current Node Architecture
Under the current design, node operators (also known as validators) must deploy two separate systems:
-
Consensus Layer: Responsible for blockchain consensus mechanisms and staking, primarily managed through the Beacon Chain.
-
Execution Layer: Handles transaction processing and smart contract execution.
Both programs require configuration, synchronization, and data transfer, making node operation relatively complex.
For many average users, this technical barrier makes running a node independently challenging.
Node Operation Barriers Affect Decentralization
Buterin argues that the current node architecture has inadvertently turned node operation into a specialized technical task. He points out that many believe node operation must be handled by professional DevOps teams, but this mindset actually hinders blockchain decentralization.
His position is:
If node deployment remains too complex, most users will rely on third-party services, which could weaken the network’s decentralization.
Time and Technical Barriers Remain Key Challenges
Buterin also notes that even users with adequate hardware and technical skills may lack the time to maintain a node.
He therefore stresses a core principle: node operation should be simpler. Only when node deployment becomes more accessible will more individuals participate in network infrastructure.
Partially Stateless Node Concept
Beyond simplifying node architecture, Buterin also proposed another design concept in May 2025: Partially Stateless Nodes.
These nodes differ from traditional ones in that:

This design can significantly reduce the resources required to run a node.
Lowering Hardware and Storage Costs
For many node operators, the main technical constraint is often disk storage. Blockchain networks—especially smart contract platforms—generate large volumes of data. As the Ethereum network expands through DeFi, NFTs, and various decentralized applications, on-chain data continues to grow.
This results in:
The Partially Stateless Node concept is designed to address this challenge.
Risks of RPC Infrastructure Centralization
Buterin also warns of another potential issue in blockchain infrastructure: RPC service centralization. If most users depend on a handful of RPC service providers to access the blockchain, several risks could arise:
-
Service providers may restrict certain users
-
Some regions may be blocked
-
Users may face censorship or deplatforming
Thus, enabling more people to run their own nodes is essential for maintaining an open network.
Vitalik’s Personal Funding Supports Technical Development
In addition to technical proposals, Buterin recently announced that he has allocated 16,384 Ether from his personal holdings, valued at approximately $45 million.
This funding will support a range of technical developments, including:
Buterin stated that these funds will be gradually invested in related research and development over the coming years.
Meanwhile, the Ethereum Foundation is entering a more restrained spending phase but will continue advancing Ethereum’s technical roadmap.
Conclusion
Vitalik Buterin’s proposals for node architecture optimization and the Partially Stateless Node concept highlight the Ethereum community’s ongoing commitment to infrastructure decentralization. By reducing the technical and hardware barriers to node operation, more individual users may participate directly in network operations rather than relying on a few large service providers. As these technologies evolve, these improvements could enhance network accessibility and further strengthen Ethereum’s long-term resilience as an open blockchain infrastructure.
