Vitalik Buterin Proposes User-Friendly Solutions for Ethereum Layer-1 Scaling

Key Insights:

• Vitalik Buterin proposes new solutions for Ethereum’s Layer-1 scaling challenges.
• The new “partially stateless nodes” concept allows users to run personal nodes despite increased gas limits.
• Ethereum co-founder addresses criticisms about full node accessibility in high-capacity networks.

itEthereum co-founder Vitalik Buterin has shared a detailed proposal to address the Ether’s Layer-1 scaling problems and still keep the feature of enabling users to run personal nodes.

The proposal is particularly aimed at addressing the widespread criticism that raising Ethereum’s gas limit would make it too complex to operate a full node for everyday users.

Vitalik Buterin on Why Node Accessibility Still Matters

Vitalik Buterin’s piece starts off by describing why single nodes remain pertinent despite the new cryptographic technologies on the horizon. Although his earlier published privacy roadmap mentioned Trusted Execution Environments (TEEs), Oblivious RAM (ORAM), and Private Information Retrieval (PIR) as trusted chain verification solutions, he proceeds to provide three reasons why single nodes are important.

Secondly, completely trustless cryptographic solutions such as single-server PIR have extortionate overhead. Buterin says that “even after many efficiency improvements, it is likely to stay expensive.” These solutions are hence not viable for a large set of users.

Besides, reliance on external RPC providers creates metadata privacy concerns, Vitalik Buterin noted. The pattern of when and how users access blockchain data through third parties can itself reveal sensitive information.

Finally, centralized RPC access points create censorship vulnerabilities. Buterin observes that “a market structure dominated by a few RPC providers is one that will face strong pressure to deplatform or censor users.” He also noted that “many RPC providers already exclude entire countries.”

Ethereum’s Short and Medium-term Scaling Priorities

Vitalik Buterin shares several steps to reduce node operation requirements in the near future. His highest short-term priority is to “up-prioritize a full rollout of EIP-4444.” This would limit blockchain data storage requirements to approximately 36 days of history.

This change would reduce disk space needs, which Buterin identifies as “the primary issue preventing more people from running nodes.”

Another short-term priority involves building a “distributed history storage solution” using erasure coding to maximize robustness. This Ethereum approach would allow each node to store only a small percentage of historical data older than the cutoff period. This ensures blockchain permanence without burdening individual node operators or relying on centralized providers.

Vitalik Buterin also recommends adjusting gas pricing to “make storage more expensive and execution less expensive.” He specifically highlights the need to increase gas costs for operations that create new states. This includes SSTORE for new storage slots, contract code creation, and sending ETH to previously unused accounts.

For medium-term improvements, Buterin prioritizes implementing stateless verification. This development would enable “RPC-capable” nodes to operate without storing state Merkle branches. This could further decrease storage requirements by approximately 50%.

Vitalik Buterin Suggests Partially Stateless Nodes

The most notable element of Vitalik Buterin’s proposal is the introduction of “partially stateless nodes.” This is designed specifically to enable personal node operation even if Ethereum’s Layer-1 gas limit increases by 10-100x. This new node type would verify blocks statelessly, validate the entire chain (either through stateless validation or ZK-EVM), but only maintain a user-selected portion of the state.

These nodes would be capable of responding to RPC requests as long as the required data falls within the subset of state they maintain. Requests for data outside this subset would fail or, optionally, fall back to “an externally-hosted cryptographic solution” based on user preference.

Notably, this approach would be managed through an on-chain contract. Users would only need to save raw values, not Merkle branches, further reducing storage requirements.

According to Vitalik Buterin, this solution would provide “the benefits of direct local access to the state that a user needs to care about, as well as maximal full privacy of access to that state.” This will effectively balance scaling needs with accessibility.
