On-chain Bitcoin is perfect for large transactions and long-term storage. But for everyday spending—coffee, tips, small purchases—the fees and wait times don't make sense.
That's where Lightning comes in.
Lightning Network = Fast Bitcoin
Think of it as Bitcoin's "cash layer":
Real-world use: Pay for coffee, tip content creators, send money globally, receive payments instantly—all without waiting for confirmations or paying high fees.
| Property | On-Chain (Layer 1) | Lightning (Layer 2) |
|---|---|---|
| Speed | 10-60 minutes | Less than 1 second |
| Fees | $1 - $50+ (depends on congestion) | $0.001 - $0.01 |
| Best For | Large amounts, savings, cold storage | Daily spending, tips, small payments |
| Security | Maximum (blockchain) | Very high (crypto secured) |
| Typical Amount | $100 - $1M+ | $1 - $1,000 |
| Privacy | Public (blockchain) | Private (off-chain) |
Use On-Chain when:
Use Lightning when:
You don't need to understand all the technical details, but here's the concept:
You lock some Bitcoin in a channel (like depositing cash in your wallet)
Send/receive unlimited times without touching the blockchain
Final balance gets recorded on the blockchain (one transaction)
Analogy: It's like opening a tab at a bar. You put money down, make multiple purchases, and settle up at the end—except everything is cryptographically secured.
For Pragmatists:
Most modern Lightning wallets handle channels automatically. You just send and receive—the wallet manages the complexity behind the scenes.

Pros:
Cons: Lightning wallet is custodial (on-chain is not)
