Ethereum Node Types Explained: Full, Archive, Validator & Light
Understanding Ethereum node types is crucial before shopping for hardware. Hardware requirements can vary dramatically based on what role your node plays. Ethereum's post-merge, proof-of-stake structure launched new validator demands and changed how full and archive nodes work.
Full Nodes
Full nodes download and verify every block, enforcing the consensus rules and relaying current state information. For most home users, this is the go-to: enough to verify mainnet activity, sync wallets, and support the network. Hardware needs are moderate—you'll need decent CPU, at least 16GB RAM, and fast SSD storage to avoid bottlenecks, especially for re-syncing or running both execution and consensus clients.
Archive Nodes
Archive nodes store all historical state data—every contract and account state at every block. This isn’t just a backup: some dapps, explorers, and research use-cases demand it. But hardware needs are steep, driven mainly by storage: in 2025, expect over 15TB and growing, plus high-speed disks and 64-128GB RAM for handling state diffs and queries. Not practical for home use.
Validator Nodes
Validator nodes participate in block proposal and attestation under proof-of-stake. Uptime and network reliability are paramount. Specs are lighter than archive/full, but the demand for always-online, uninterrupted operation is severe: low latency internet and power backups are essential. Missed duties lead to lost rewards or slashing. OKX staking solutions can shield validators from these risks by offering managed uptime, redundancy, and strict penalty prevention for your staked ETH, without hardware headaches.
Light Nodes
Light nodes don’t store the full blockchain or state. They rely on full nodes for block headers and verify only what users need—great for wallets and embedded devices, but not for validators. Hardware requirements are minimal—a Raspberry Pi or basic VM is often enough.
Choosing Your Client: Geth, Nethermind, Erigon & More
Your hardware needs depend almost as much on your choice of Ethereum client software as on node type. Post-Merge, you run one execution client (Geth, Nethermind, Erigon, Besu) plus one consensus client (Prysm, Lighthouse, Teku, Nimbus).
Execution Clients
- Geth: Most popular, moderate storage (1.3–2TB in 2025), robust, user-friendly. Needs 4+ cores, 16GB+ RAM for best results.
- Nethermind: Focus on efficiency and C# codebase. Lower RAM than Geth; works well with SSD storage, execution performance strong.
- Erigon: Rebuilt for blazing-fast sync and low-disk footprint—prized by power users. Can run with ~1TB disk, but best on NVMe. CPU-intensive on initial sync.
Consensus Clients
- Prysm, Lighthouse, Teku, Nimbus: All support validator duties, with 4-8GB RAM sufficient and modest CPU. Lighthouse is especially lightweight; Teku scales for enterprise.
Why it matters: Some combinations have heavier storage or CPU loads. Enterprise users should benchmark with their client combo. For hands-off staking, OKX infrastructure abstracts all client-side complexity while maintaining strict uptime targets for your ETH.
Full Node Hardware Requirements: CPU, RAM, SSD & Bandwidth
Operating a full Ethereum node in 2025 means planning for blockchain and state growth. Here’s how specs break down:
CPU & RAM
- Minimum: 4-core CPU (modern x86/ARM), 16GB RAM
- Recommended: 6–8 core CPU, 32GB RAM for local and remote access
More RAM allows for smoother reorgs, archive calls, and prevents OOM errors as the chain state grows. Multi-core CPUs help with parallel tasks, especially if running execution/consensus together.
Storage: SSD or NVMe?
- Minimum: 1TB SSD required for a new full node sync; 1.5–2TB recommended for 1–2 years future-proofing
- Best: NVMe SSDs for high endurance and maximum read/write speeds. SATA SSDs are acceptable short-term but wear out faster. Avoid HDDs—they’re too slow and error-prone.
Pro Tip: 💡 Budget for twice your initial storage to account for 2025–2027 chain growth and model upgrades.
Network/Bandwidth Needs
- Minimum: 25 Mbps download/upload stable; recommended 50+ Mbps for quicker sync.
- Monitor monthly data—both sync bursts and ongoing upload for relay to light nodes/peers. While home bandwidth often suffices, enterprise deployers should prioritize symmetrical, SLA-backed lines to avoid interruptions.
Power draw: Expect 80–120W for desktop builds, 200W+ for server or multi-node setups.
Archive Node & Validator Hardware: Special Considerations
Some tasks demand special hardware. Archive and validator nodes have unique needs in 2025.
Archive Node Storage & Performance
- Data size: Project 16–20TB for a new archive node sync in 2025. This outgrows even many enterprise SSDs.
- Disks: Enterprise NVMe with high DWPD (drive writes per day) ratings; consumer disks will burn out.
- RAM: 64–128GB ECC RAM; advanced users may need 256GB+ for heavy history queries.
- CPU: 8–32 core CPUs advised for archival queries and index building.
- Power: 200–500W+ for server-class setups; ensure rack cooling and dual PSUs.
Validator Node Bandwidth & Uptime
- Network: Stable, low-latency internet—10 Mbps minimum, 25 Mbps recommended.
- Uptime: Use a UPS (battery backup) and redundant power strips/local failover to avoid slashing.
- RAM/CPU: 8GB RAM minimum, 16GB preferred; quad-core CPUs sufficient, but more for multi-validator or additional workloads.
Future-Proofing & Scalability: Planning for State and Blockchain Growth
Ethereum’s chain state and historical data have consistently expanded: state grows ~0.5–1GB/week, history even faster. For a 1–3 year build, over-provision RAM and disk space:
- Buy double the minimum needed SSD/NVMe.
- Prefer motherboards with extra RAM slots for future upgrades.
- Modular cases/drives enable adding storage without full rebuilds.
Planning today saves time, money, and headaches tomorrow.
Power, Cooling & Environmental Considerations
Node hardware runs 24/7, and comfort counts—especially at home.
- Power usage: Full node rigs: 80–120W, archive/enterprise: 200–500W+.
- Noise/heat: Compact cases with quiet fans minimize disruption; consider under-desk or closet enclosures for home.
- Cooling: Keep airflow unobstructed and check intake filters monthly.
- Redundancy: UPS (battery backup) shields against brownouts, while surge protectors defend against power spikes.
Pro Tip: 💡 Silent rigs and passive cooling reduce disruption for home staking.
