Blockchain Server Costs: What You Need To Know

One of the first questions you hit when building on chain is often:
"Do I run my own node, or just plug into a provider?"

On paper, spinning up a node looks easy. Rent a server, sync the chain, expose an RPC, done. In practice, the real costs, money, time, and headaches, stack up fast.

Let’s break down what “server costs” actually mean, look at some real numbers for Ethereum and Solana, and see why most teams end up choosing managed infra instead of DIY.

First, what’s a “blockchain server” anyway?

Call it a node if you like, it’s the piece of infra that keeps the chain alive. It stores the data, validates transactions, and makes sure consensus rules are followed. Depending on what you’re building, you might need:

- Full nodes: store and verify the chain from top to bottom.‍

- Archive nodes: keep every historical state (needed for queries like eth_getBalance at block 12,345,678).

‍- Light nodes: pull only headers and ask full nodes for the rest.

- Validators / miners: actually propose and produce blocks.

Each type has its own hardware, storage, and bandwidth demands, and that’s where the money goes.

Where the costs come from

Running blockchain infra isn’t like renting a single web server. You’re on the hook for:

Hardware & setup
Think CPUs with 16–64 cores, 64–256 GB RAM, and multi-terabyte NVMe SSDs. A single decent node box can run you anywhere from $800–$3,800 upfront. Archive or validator nodes are way above that.

Operational expenses
If you’re on-prem, that’s power, cooling, and bandwidth. If you’re on cloud, it’s compute, storage, and egress. For Ethereum, expect $1,500–$5,000/month per node.

Maintenance & upgrades
Syncs break, forks happen, clients need patching. Budget 10–20% of project cost per year just for upkeep.

Scaling
One server isn’t enough if you care about redundancy or latency. Production apps usually need nodes in US, EU, and APAC. Costs triple overnight.

Security & compliance
Firewalls, DDoS protection, logging, audits. Nobody budgets for these at the start, but you’ll need them.

And then there are the hidden costs: slow responses under load, tracer/debug calls that fail, chain-specific quirks (like Arbitrum’s pre-Nitro debug gaps), and the human cost of someone being on-call when a node dies at 3am your local time but peak time for your client/user.

Case 1: Ethereum archive node

Let’s say you’re building a DeFi dashboard and need balances, tx history, and historical queries. That means you need at least one full node and one archive node.

• Compute (16–32 vCPUs, 64–128 GB RAM): ~$2,500/month
• Storage (~15 TB NVMe SSD): ~$1,800/month
• Bandwidth (~5 TB out): ~$450/month

👉 Baseline: ~$4,750/month
👉 Annual: ~$57,000

But you can’t run just one node in prod. You’ll want redundancy + multi-region coverage, which takes you past $170k/year. Add a DevOps engineer (~$100k/year), and you’re easily at $250k/year for Ethereum infra alone.

Case 2: Solana RPC node

Solana’s whole value prop is high throughput, but that comes at the cost of beefy infra. Running a Solana RPC or validator isn’t cheap.

• Compute (64 vCPUs, 256 GB RAM): ~$3,300/month
• Storage (8 TB NVMe SSD): ~$1,000/month
• Bandwidth (~10 TB out): ~$900/month

👉 Baseline: ~$5,200/month
👉 Annual: ~$62,000

Now, real Solana RPC setups usually mean 3–5 nodes per cluster for load and failover. That’s $200k–$300k/year. If you’re running a validator too, you also need millions in staked SOL on top.

Why these numbers matter

Even if you eat the infra bill, you’re still wrestling with:

Latency: self-hosted RPCs often sit around 200–500ms. Good UX needs sub-50ms.

Heavy calls: debug_traceTransaction and friends eat CPU for seconds, sometimes fail outright.

Archive queries: without an archive node, past balances just… don’t work. Maintaining one adds massive storage overhead.

Scale across chains: need Ethereum, Solana, and Polygon tomorrow? Congrats, you’ve just tripled your problems.

For most teams, that means less time building products, more time keeping servers alive.

The Tatum path: skip the pain

This is where Tatum changes the math. Instead of burning $250k+ a year to keep Ethereum and Solana nodes humming, you just use:

RPC Gateway: sub-30ms latency, 99.9% uptime, 130+ chains, one endpoint.

Data API: indexed balances, tx history, token ownership, no need to run your own explorers.

Notifications: real-time webhooks for transfers, contract events, and failed txs.

Archive access: live + historical data from the same endpoint, no extra nodes required.

You get production-grade infra on demand, starting free and scaling by usage. No clusters, no DevOps payroll, no sleepless nights.

Bottom line

Yes, you can run your own nodes. Ethereum? Around $250k/year for a real setup. Solana? $200k–$300k/year for a cluster. And that’s before you count the people hours.

For most dev teams, it makes zero sense. Managed infra is faster, cheaper, and more reliable. That’s exactly what Tatum gives you: global RPC, indexed data, and notifications, all priced on usage.

Milliseconds matter. So does your budget. If you’re building on Ethereum, Solana, BSC, Tron, Base, or 130+ other chains, test it yourself with Tatum RPC Gateway.
