Ethereum co-founder Vitalik Buterin has unveiled a bold new scaling roadmap aimed at solving one of blockchain’s most persistent challenges: how to scale Layer 1 (L1) without compromising decentralization. At the heart of this vision is a novel concept—partially stateless nodes—a technical innovation designed to dramatically increase Ethereum’s gas limits while preserving the ability for everyday users to run full nodes.
This proposal strikes at the core of Ethereum’s long-term sustainability, addressing growing concerns about network bloat, rising hardware requirements, and the centralization risks associated with high resource demands. By rethinking how nodes interact with blockchain state, Buterin outlines a path toward a more scalable, accessible, and resilient Ethereum.
The Challenge of Scaling Layer 1
Scaling Ethereum has largely focused on Layer 2 (L2) solutions like rollups, which offload computation from the main chain. While effective, L2s don’t eliminate the need for a robust and scalable L1. In fact, as L2s grow, they increasingly rely on Ethereum’s base layer for data availability and security—putting even greater pressure on L1 throughput.
Traditionally, increasing the gas limit—a cap on computational work per block—has been seen as a quick way to boost capacity. However, this approach comes with major trade-offs. Higher gas usage means more data processing and storage demands for full nodes, which could push smaller validators out of the network and threaten decentralization.
Buterin emphasizes that running full nodes is not just a technical preference—it's a foundational pillar of trustless, censorship-resistant, and privacy-preserving access to the blockchain. If only large institutions can afford to run nodes, Ethereum risks becoming centralized in practice, even if it remains decentralized in theory.

Short-Term Strategies: Reducing Node Burden
To pave the way for higher gas limits without sacrificing node accessibility, Buterin outlines several near-term priorities:
Implement EIP-4444: Limit Historical Data Retention
One of the most impactful steps is EIP-4444, which proposes limiting the amount of historical blockchain data that nodes must store—specifically, restricting it to the last 365 days (commonly referred to as "pruning"). Currently, running a full Ethereum node requires storing over 1TB of state data and around 500GB of historical blocks, creating significant barriers for average users.
By pruning old data, EIP-4444 drastically reduces disk space requirements, enabling more individuals to participate in network validation. Archived data would still be available through decentralized retrieval systems, ensuring long-term integrity without burdening every node.
Build Decentralized Historical Data Storage
With less data stored locally, Ethereum needs a reliable way to access older information when needed. The solution lies in decentralized data availability layers, where historical blocks are stored across peer-to-peer networks like IPFS or BitTorrent-like protocols. This ensures data persistence while distributing storage costs across many participants.
Optimize Gas Cost Structure
Another key short-term lever is adjusting Ethereum’s gas pricing model. Buterin suggests increasing costs for storage operations while reducing fees for execution. This economic incentive encourages developers to write more efficient smart contracts—minimizing bloat and improving overall network health.
These changes collectively lay the groundwork for a leaner, more efficient Ethereum—one where running a node remains feasible for a broad range of users.
Mid-Term Vision: Stateless Verification
Looking ahead, Buterin highlights stateless verification as a transformative mid-term upgrade. In a stateless model, nodes can validate transactions and blocks without storing the entire blockchain state. Instead, they receive cryptographic proofs—such as Merkle branches—that confirm the validity of specific data points.
This shift reduces node storage requirements by up to 50%, making it easier to run validators on consumer-grade hardware. It also enhances security by minimizing reliance on trusted third parties for state information.
Stateless verification sets the stage for more advanced architectures—including partially stateless nodes.
Introducing Partially Stateless Nodes
The centerpiece of Buterin’s new roadmap is the introduction of partially stateless nodes. These hybrid validators combine elements of stateless verification with selective state retention. Rather than storing all blockchain data or none at all, these nodes keep only a portion of the state—such as frequently accessed accounts or contract code—while relying on cryptographic proofs for the rest.
This design enables nodes to:
- Fully verify blocks and transactions
- Execute queries on locally stored data
- Maintain high performance with reduced resource usage
Crucially, partially stateless nodes could allow Ethereum to safely increase its gas limit by 10x to 100x, unlocking massive scaling potential directly on L1. This would support more complex applications, higher transaction volumes, and denser rollup data inclusion—all without forcing users into centralized infrastructure.

Frequently Asked Questions
Q: What are partially stateless nodes?
A: Partially stateless nodes are Ethereum validators that store only a subset of the blockchain state while using cryptographic proofs to verify the rest. They balance efficiency and functionality, enabling higher throughput without full data storage.
Q: How do partially stateless nodes improve scalability?
A: By reducing storage and bandwidth requirements, more users can run nodes. This supports higher gas limits and increased L1 capacity—potentially 10–100x current levels—without sacrificing decentralization.
Q: What role does EIP-4444 play in this roadmap?
A: EIP-4444 limits historical data retention to one year, significantly lowering storage needs for full nodes. This makes it easier for individuals to participate in network validation and supports future scaling upgrades.
Q: Will this make Ethereum less secure?
A: No—security is preserved through cryptographic verification. Even with less data stored locally, nodes can validate blocks using Merkle proofs and other trustless mechanisms.
Q: Can average users still run Ethereum nodes under this model?
A: Yes, that’s a primary goal. By reducing hardware demands via pruning, stateless verification, and partial state storage, node operation remains accessible to non-enterprise users.
Q: When will partially stateless nodes be implemented?
A: While still in the research phase, components like EIP-4444 are already being tested. Full deployment may take several years, depending on protocol upgrades and client adoption.
Challenges Ahead
Despite its promise, this new architecture introduces complexity. Implementing partial state management requires deep changes to both consensus and execution layers. Additionally, having different types of nodes with asymmetric roles could lead to coordination challenges or new attack vectors if not carefully designed.
There’s also the risk of fragmentation—if too many nodes adopt different state subsets, network-wide consistency could suffer. Robust protocols will be needed to ensure synchronization and prevent divergence.

Conclusion
Vitalik Buterin’s proposal for partially stateless nodes represents a paradigm shift in how we think about blockchain scalability. Rather than choosing between performance and decentralization, this approach seeks to achieve both—by reengineering how nodes handle data.
With strategic short-term optimizations like EIP-4444 and long-term innovations like stateless verification, Ethereum is building a foundation for sustainable growth. The journey toward 10x–100x L1 scaling is complex, but with thoughtful engineering and community alignment, a faster, leaner, and more inclusive Ethereum is within reach.
