Ethereum co-founder Vitalik Buterin says the boom in home artificial-intelligence hardware is making it significantly easier to run an Ethereum node, revealing that his own pruned Geth setup occupies just 461 GiB of storage on a single machine. In a post on X shared on September 26, 2026, Buterin noted that a full node can now synchronize in roughly half a day, and that enthusiasts buying computers to run local large language models already receive fast NVMe drives and ample storage — capacity that can simultaneously host a pruned Ethereum database.

That overlap eases hardware demands and lets node operators check network data directly rather than relying on third-party RPC providers, as reported by Blockonomi. The 461 GiB figure reflects one specific setup, however; client selection, pruning settings, and the network's continued growth can all alter storage requirements.

Buterin: an Ethereum Node Can Now Sync in Half a Day

Reminder: you can now sync an ethereum node within half a day and with aggressive settings the space it takes up on disk can be under half a terabyte.

Ethereum Nodes Fit Within Local AI Systems

High-performance desktops built for local AI workloads typically pair powerful graphics cards with large NVMe drives. Examples include systems using NVIDIA RTX 5090 cards and compact AI workstations such as the DGX Spark. Those machines need storage for large language model weights and related files, and the same capacity can support a pruned database, letting users run AI workloads and an Ethereum node on a single computer.

The overlap allows home computers to act as independent verification points rather than terminals that depend cloud infrastructure. A combined setup gives operators both chain data and a way to verify information directly against the network. Each independently operated node also spreads the work of checking transactions and balances across more participants, which has long been part of Ethereum's decentralization model.

Faster Synchronization Reduces the Setup Burden

Buterin attributed the shorter setup time to optimizations in Geth's snap sync process and work related to EIP-4444. Under the conditions he described, a full node can synchronize in roughly 12 hours.

EIP-4444 is a history-expiry proposal that would limit how much historical chain data nodes are expected to serve and retain, an approach intended to keep node operation manageable as the chain ages.

Snap sync lets Geth — one of Ethereum's most widely used execution clients — obtain a recent network state without replaying every earlier state. Pruning removes older data that a standard full node need not retain, reducing the information stored locally. Together, the two techniques cut both the download volume and the processing work required during synchronization, meaning operators can begin using a local Ethereum node sooner under the conditions Buterin described.

The shorter synchronization window also changes the practical experience for new operators. Users can reach a working local setup faster, while AI hardware supplies the processing power and storage needed for the initial download. Existing high-end AI workstations can therefore support independent blockchain verification alongside local model workloads.

Ethereum Storage Guidance Still Allows Extra Headroom

The 461 GiB figure describes Buterin's configuration, not a fixed requirement for every operator. Different clients, settings, and future blockchain growth can change how much storage a node requires, so readers should treat the number as a current example of a pruned setup rather than a replacement for Ethereum's hardware guidance for longer-term installations.

Ethereum's general guidance still recommends a 2 TB NVMe drive. That capacity gives operators considerably more room than the pruned setup uses and delays immediate hardware changes as the chain grows, accommodating future client growth without requiring a drive replacement.

The lower current footprint nonetheless makes home verification more accessible to owners of suitable computers. Instead of only querying remote services, these users can check blockchain data through infrastructure they operate themselves. That distinction also gives AI hardware a second use between model runs: the machine can support local applications while maintaining the files and processes needed for independent blockchain verification.

Local Nodes Do Not Remove Every Privacy Concern

Running a node locally does not guarantee that wallet activity stays private. A wallet or application can still send requests through a commercial RPC provider, exposing information about addresses and transactions.

Buterin has linked those concerns to work on Kohaku tools and command-line wallets. Kohaku focuses on Ethereum wallet tools, while the experimental command-line wallet targets private balances. These efforts address the application layer, while the node supplies local blockchain data — leaving both the wallet software and the connection method important for users seeking more direct control over their data.

The planned Glamsterdam upgrade is expected to accelerate synchronization further at Ethereum's base layer. Its development could reduce setup and maintenance time for individual node operators, and client release notes around that rollout remain the practical reference point for tracking future sync and storage changes.
