Ethereum co-founder Vitalik Buterin recently unveiled a proposal designed to preserve Ethereum's trustless, censorship-resistant access capabilities while maintaining these core features even as the network continues to scale.
The Need for User-Friendly Node Operation
On May 19, Buterin published an article detailing how to make Ethereum's Layer 1 scaling more "user-friendly" for individuals running local nodes. The Ethereum co-founder emphasized the importance of independent users operating nodes, highlighting the severe censorship risks in a market dominated by a few Remote Procedure Call (RPC) providers.
👉 Why Ethereum decentralization matters
RPC providers enable wallets, users, and applications to interact with the blockchain without running their own nodes. In practice, cryptocurrency wallets often silently connect to RPC providers in the background. Buterin identified this architectural design as potentially risky.
"A market structure dominated by a handful of RPC providers creates strong pressure to ban or censor users. Several RPC providers have already completely blocked access from specific countries," Buterin stated in his article.
Introducing Partial Stateless Nodes
Beyond censorship concerns, Buterin argued that the high cost of completely trustless cryptographic solutions and the need for metadata privacy protection demonstrate the value of creating a more accessible environment for individual node operators.
How Partial Stateless Nodes Work
The proposal centers on an innovative node design called "partial stateless nodes." These nodes are specifically designed to:
- Help users maintain private access to blockchain data
- Significantly reduce resource consumption compared to traditional full nodes
- Allow selective state data storage based on individual needs
As the Ethereum network grows and gas limits increase, running full nodes requires progressively more storage space and network bandwidth. Partial stateless nodes address this by enabling users to:
- Verify the blockchain
- Provide local data services
- Only store subsets of Ethereum state relevant to their specific requirements

Stateless Block Validation
These nodes would validate blocks in a stateless manner, meaning they:
- Don't require full Merkle proofs
- Don't need to store complete blockchain history
- Can selectively maintain updates to specific state data
Users could configure their nodes to only store data related to:
- Their own accounts
- Frequently used DeFi applications
- Regularly traded tokens (such as stablecoins and ETH)
Any queries beyond the stored subset would either fail or be redirected through RPC solutions for processing.
Frequently Asked Questions
Why is node decentralization important for Ethereum?
Decentralized node operation prevents censorship risks and maintains Ethereum's trustless properties. When too few entities control node infrastructure, they can exert disproportionate influence over network access.
How do partial stateless nodes differ from full nodes?
Partial stateless nodes store only selected portions of blockchain state rather than maintaining complete copies. This reduces resource requirements while still allowing users to verify chain integrity.
What are the main benefits of this proposal?
The solution aims to:
- Lower barriers to independent node operation
- Preserve decentralization as Ethereum scales
- Maintain privacy for node operators
- Reduce hardware requirements for participation
