Bitcoin Knots vs Bitcoin Core: Which Node Should You Run? (2026)Bitcoin Knots vs Bitcoin Core 2026: same consensus rules, different mempool policy. Which node should you run? Full comparison of features, security, and use cases.
Running a Bitcoin Lightning routing node lets you earn satoshis by forwarding other people's payments across the Lightning Network. The honest answer: most nodes earn very little. A well-managed, well-capitalized routing node earns $5-$50/month in routing fees. An average node earns less than $1/month. But routing nodes aren't just about profit — they strengthen the network, improve your payment privacy, and give you direct access to Bitcoin's instant settlement layer.
This guide explains how Lightning routing works, what real routing income looks like, and whether running a node makes sense for you.
How Lightning Routing Fees Work
When you send a Lightning payment, it travels through a path of nodes connected by payment channels. Each intermediate node along the path earns a small fee for forwarding the payment.
Fees have two components:
Base fee: A flat amount charged per payment, regardless of size. Typical range: 0-1,000 millisatoshis (msat). At 1,000 msat, that's 0.001 sat per payment.
Proportional fee (ppm): A fee proportional to the payment amount, measured in parts per million. At 100 ppm, you earn 100 sats on a 1,000,000 sat ($1 at $100k BTC) payment.
To earn $50/month at 100 ppm, your node needs to route ~$50,000 worth of payments per month. At 500 ppm, you'd need to route ~$10,000/month. Volume is the limiting factor for most nodes.
What Real Routing Nodes Actually Earn
Based on community data from public routing node operators:
| Node Setup | Monthly Routing Volume | Fee Rate | Monthly Earnings |
|---|---|---|---|
| New node, 3-5 channels | $500-$2,000 | 100-300 ppm | $0.50-$6 |
| Established node, 10-20 channels | $5,000-$20,000 | 100-200 ppm | $5-$40 |
| Well-optimized hub, 50+ channels | $50,000-$200,000 | 50-150 ppm | $25-$300 |
| Top-tier routing node, 200+ channels | $500,000+ | 30-100 ppm | $150-$500 |
The top 10% of routing nodes handle the majority of Lightning volume. Getting into that tier requires significant capital ($10k-$100k in channel liquidity), active channel management, and good positioning relative to major hubs.
Hardware Requirements
You can run a Lightning node on:
Raspberry Pi 4 (4-8GB RAM): ~$80 hardware cost. Runs Umbrel or RaspiBlitz well. Needs a 1TB+ SSD ($60-$100). Total setup: ~$150-$200.
Old laptop or desktop: If you have one lying around, repurpose it. Bitcoin Core + LND runs fine on any modern laptop with 8GB RAM and 1TB storage.
Always-on VPS (cloud server): $5-$15/month from any cloud provider. Convenient but introduces a custodial element — your node keys live on rented hardware.
Dedicated node appliances: Plug-and-play boxes like the Bitcoin Merch X Node Mini run the full stack out of the box. More expensive but zero setup.
Node Software: LND vs Core Lightning vs Eclair
| Software | Use Case | Strengths | Channel Support |
|---|---|---|---|
| LND (Lightning Labs) | Most popular, widest ecosystem | Loop, Pool, Taproot channels, broad app support | Best |
| Core Lightning (CLN) | Performance-focused, plugin system | Fastest, most efficient, best for big nodes | Excellent |
| Eclair | ACINQ's node implementation | Production-tested, Phoenix Wallet backend | Good |
| Alby Hub | Self-custody Lightning for wallets | Best for personal use/wallet backend | Basic |
For routing, LND is the most common choice due to ecosystem tools. Core Lightning is preferred by high-volume operators for its performance.
Node Management Interfaces
Umbrel: App-store style interface, easiest setup, runs LND by default. Best for beginners. See our Umbrel vs Start9 vs RaspiBlitz comparison.
ThunderHub: Web UI for LND nodes — channel management, fee adjustment, rebalancing. Free.
RTL (Ride The Lightning): Older but feature-complete LND/CLN dashboard. Free.
Amboss / 1ML: Network explorer tools for analyzing your node's graph position and routing performance.
Channel Strategy: How to Actually Route Payments
Having a node means nothing without well-placed channels. Channels need:
Capital: Each channel locks up funds on both sides. A $500 channel gives you $500 to route toward the counterparty. You need $5,000-$20,000 in total channel capacity to be a meaningful routing node.
Liquidity balance: Channels need liquidity on the right side. Inbound liquidity (funds on your counterparty's side) lets you receive payments routed toward you. Outbound liquidity (your funds) lets you forward payments toward others. Managing this balance — via circular rebalancing or services like Loop Out — is the main ongoing work of routing.
Good peers: Connect to well-connected nodes near the center of the graph. Use Amboss or LNRouter to identify high-traffic routing nodes. Opening channels to obscure nodes with low connectivity won't earn routing fees.
Competitive fees: Starting at 50-100 ppm with a low base fee (0-500 msat) attracts routing. You can raise fees on channels where you're providing rare liquidity.
The Real Costs of Running a Routing Node
- Channel open/close fees: Each channel requires an on-chain Bitcoin transaction ($2-$20+ depending on fees). Opening 20 channels could cost $40-$400 in transaction fees.
- Rebalancing costs: Keeping channels balanced via circular payments costs fees (typically 20-50 ppm per rebalance)
- Your time: Active channel management takes 30-60 minutes per week for a serious routing node
- Opportunity cost: Capital locked in channels doesn't earn yield elsewhere
When Running a Lightning Node Makes Sense
Good reasons to run a node:
- You want to verify your own Bitcoin transactions without trusting third parties
- You want a private Lightning wallet with no KYC (connect your personal wallet to your own node)
- You want to understand Lightning deeply and are willing to invest time learning
- You run a business that accepts Lightning payments and want self-sovereignty
Bad reasons to run a node:
- You expect meaningful passive income without significant capital and active management
- You want to "mine" Lightning fees the way you mine Bitcoin (the analogy doesn't hold)
Getting Started
- Follow our Bitcoin node setup guide to get Bitcoin Core synced
- Install LND on top (Umbrel bundles both together)
- Fund your node wallet with 0.01-0.1 BTC to open initial channels
- Open 3-5 channels to well-connected peers using Amboss recommendations
- Use ThunderHub to monitor routing activity and adjust fees
- After 30 days, evaluate whether routing is working and expand or pivot
FAQ
How much Bitcoin do I need to run a routing node? 0.01 BTC (~$950 at $95k BTC) is a minimal starting point. Meaningful routing typically requires 0.1-1 BTC in channel capacity.
Is routing Lightning nodes legal? Yes. You're forwarding encrypted payment data — similar to running a Tor exit node in concept, but with less legal ambiguity since the payments are Bitcoin transactions on a transparent network.
Do I need to keep my node online 24/7? Yes. Offline nodes can't route payments and may have channels force-closed by counterparties if you're offline too long. A Raspberry Pi on a reliable home internet connection works fine.
What's the difference between a routing node and a wallet-only node? A wallet-only node (like one run via Umbrel for personal use) doesn't actively route payments — it just gives you self-custody Lightning payments without earning routing fees. A routing node opens many public channels and actively manages liquidity to earn fees from third-party payments.
