Vitalik Buterin Proposes Multi-Tiered State Design for 1000x Ethereum Scaling

Ethereum co-founder Vitalik Buterin has proposed a multi-tiered state design intended to achieve 1000x scalability on the Ethereum Layer 1 (L1). The plan targets "state scaling," which Buterin identifies as a fundamentally more difficult challenge than scaling execution or data.

To reach this target, the proposal introduces new, more restrictive forms of state storage to operate alongside the existing permanent state. This architecture includes temporary storage that resets on a monthly basis and a UTXO-style (Unspent Transaction Output) approach for specific data types. Under this model, high-value items such as user accounts and smart contract code would remain in permanent storage, while lower-value items, including token balances and NFTs, would migrate to temporary storage or UTXOs.

The State Growth Bottleneck

While Ethereum has established paths for scaling execution through ZK-EVMs and data via PeerDAS, the "state"—the comprehensive record of all accounts and balances—remains a critical bottleneck. Currently, the Ethereum state grows by approximately 100 GB annually. According to the proposal, a 20x increase in network activity could result in 8 TB of state growth over just four years, creating unsustainable hardware and storage requirements for block builders.

Previous attempts to address this through "strong statelessness" or state expiry were hindered by increased bandwidth costs and significant backwards compatibility issues with existing ERC20 contracts. The multi-tiered approach seeks to bypass these hurdles by diversifying how data is stored based on its utility and value.

Implications for the Network

If implemented, this shift would allow Ethereum to increase its throughput by orders of magnitude without pricing out permissionless block builders. By moving the bulk of the network's data into a more efficient UTXO-like model, the network can drastically reduce the hardware requirements for running a node. This ensures that the network remains decentralized while maintaining the composability required for core DeFi contracts.

The Path Forward

The proposal marks a strategic pivot toward a hybrid storage model to ensure long-term sustainability. While the technical framework for execution and data scaling is largely understood, the transition to a multi-tiered state will require careful coordination to avoid disrupting existing ecosystem assets. Observers will now be watching for community feedback and technical refinements to the proposed temporary storage and UTXO integration.
