Vitalik Buterin noted Ethereum currently needs over 1 TB for state plus about 0.5 TB for history, pushing full‑node storage above 1.5 TB and discouraging typical users

Currently, operating a full Ethereum node requires significant disk space, often over 1 TB, making it impractical for most users. While third-party services offer access to blockchain data, they come with privacy and censorship trade-offs, Buterin noted.

Running a full Ethereum node requires storing the entire blockchain state (~1TB for state, ~500GB for history). EIP-4444 would offload historical data storage, making nodes lighter.
