Ethereum co-founder Vitalik Buterin has revealed a bold new vision for the network’s long-term scalability, centered around a groundbreaking concept known as "partially stateless nodes." This proposal aims to tackle one of blockchain’s most persistent challenges: achieving significant Layer 1 (L1) scaling without compromising decentralization or increasing node operation barriers.
As Ethereum continues to grow in usage and complexity, the burden on full nodes—critical components that validate and store the entire blockchain state—has become a major bottleneck. With current node requirements exceeding 1TB of state data and 500GB of historical data, concerns about centralization risks are mounting. Buterin’s latest roadmap outlines a strategic path forward, blending short-term optimizations with transformative mid-term innovations.
The Challenge of L1 Scaling
Scaling Ethereum at the base layer has always been a delicate balancing act. While increasing the gas limit could theoretically allow more transactions per block, it comes at a cost: heavier computational and storage demands on nodes. Critics have long argued that pushing L1 limits too far would exclude regular users from running nodes, undermining Ethereum’s core principles of decentralization, security, and trustless access.
Buterin emphasizes that full node operation isn’t just a technical detail—it's a cornerstone of user sovereignty. Running a node enables individuals to interact with the blockchain directly, without relying on third-party services, ensuring anti-censorship, privacy, and verification autonomy.

Short-Term Strategies: Reducing Node Burden
To lay the foundation for higher throughput without immediate architectural overhauls, Buterin outlines several near-term priorities focused on reducing resource demands:
Implement EIP-4444: Limiting Historical Data Retention
EIP-4444 proposes capping the amount of historical blockchain data that nodes must store—limited to approximately 36 days. This change dramatically reduces disk space requirements, making it feasible for more users to run full nodes on consumer-grade hardware. By offloading older data to archival networks, Ethereum maintains verifiability while improving node accessibility.
Decentralized Historical Data Storage
Instead of requiring every node to retain the full chain history, the network can adopt distributed storage solutions—such as IPFS or Swarm-like protocols—where historical blocks are preserved across a decentralized ecosystem. This shift ensures data availability without central points of failure.
Optimizing Gas Cost Structure
Adjusting the gas pricing model to reflect real computational costs is another key lever. By increasing fees for state storage and reducing them for execution, the network incentivizes developers to write more efficient smart contracts. This economic nudge discourages bloat and promotes leaner, more sustainable dApp designs.
These measures collectively aim to flatten the growth curve of node resource demands, creating breathing room for deeper architectural changes down the line.
Mid-Term Vision: Stateless Verification and Efficiency Gains
Looking ahead, Buterin identifies stateless verification as a pivotal evolution in Ethereum’s architecture. In a stateless model, validators can verify transactions and blocks without maintaining a complete copy of the blockchain state. Instead, they rely on cryptographic proofs—like Merkle branches or witness data—provided alongside each transaction.
This approach slashes storage needs by up to 50%, enabling lighter, faster nodes. More importantly, it decouples validation from data storage, opening doors to greater scalability. However, it introduces new complexities: transactions become larger due to attached proof data, and network bandwidth requirements increase.
Still, when combined with advancements like verkle trees—a more efficient alternative to Merkle trees for state representation—stateless verification could become a cornerstone of Ethereum’s future scalability stack.
Introducing Partially Stateless Nodes
At the heart of Buterin’s new roadmap is the innovative concept of partially stateless nodes. These hybrid validators represent a middle ground between fully stateful and fully stateless designs.
A partially stateless node:
- Does not store the entire blockchain state
- Maintains only a subset of frequently accessed data
- Uses cryptographic techniques (e.g., zkEVM proofs or Merkle witnesses) to verify transactions outside its local dataset
- Can still perform queries and validations on its retained portion of the state
This design allows nodes to remain lightweight while preserving high levels of security and functionality. Crucially, it enables Ethereum to safely raise the L1 gas limit—potentially by 10x to 100x—without forcing every participant to bear the full cost of global state growth.
Unlocking L1 Scalability Potential
By reducing the per-node storage burden and enabling selective state access, partially stateless nodes could unlock unprecedented throughput on Ethereum’s base layer. This means:
- Faster transaction finality
- Lower fees during peak demand
- Greater resilience against centralization pressures
Moreover, this model supports a more diverse ecosystem of node operators—from individual enthusiasts to institutional validators—each tailoring their setup based on use case and resources.
However, challenges remain. Implementing partial state management requires deep changes to both the consensus and execution layers. There are also potential risks related to network asymmetry, where different node types may behave differently under stress, leading to synchronization issues or security edge cases.

Frequently Asked Questions (FAQ)
What are partially stateless nodes?
Partially stateless nodes are Ethereum validators that store only a portion of the blockchain state while using cryptographic proofs to verify transactions beyond their local data. They balance efficiency with full validation capability.
How do partially stateless nodes improve scalability?
By reducing storage requirements, these nodes make it easier to run validators, allowing Ethereum to safely increase the gas limit and process more transactions per block—potentially scaling L1 throughput by 10–100x.
What is the difference between stateless and partially stateless nodes?
Fully stateless nodes rely entirely on external proofs and store no state. Partially stateless nodes keep selected parts of the state locally, enabling faster access and query capabilities for specific applications or services.
Will this compromise Ethereum’s security?
Not inherently. Security relies on cryptographic verification rather than universal data storage. As long as enough nodes collectively cover the full state, the network remains secure.
How soon could this be implemented?
While EIP-4444 and gas adjustments are near-term goals, partially stateless nodes require extensive research and protocol upgrades. Realistic deployment timelines likely span several years, aligned with Ethereum’s broader roadmap phases.
Do users still need rollups if L1 scales this much?
Yes. Even with enhanced L1 capacity, Layer 2 rollups will continue playing a vital role in achieving mass adoption. They offer specialized scaling for specific use cases and further reduce costs through batching and compression.

Conclusion
Vitalik Buterin’s proposal for partially stateless nodes marks a strategic pivot in Ethereum’s scaling philosophy—one that embraces architectural innovation over brute-force expansion. By rethinking how nodes interact with blockchain data, Ethereum can pursue aggressive L1 scaling while safeguarding its foundational values of decentralization and user empowerment.
This roadmap doesn’t replace Layer 2 solutions; instead, it strengthens the entire ecosystem by creating a more robust, flexible base layer. As research progresses and testnets evolve, the vision of a high-throughput, low-barrier Ethereum inch closer to reality.
For developers, node operators, and users alike, the future of Ethereum looks not just faster—but more inclusive.
