Payment Layer

Lightning Network

Bitcoin settles large transactions permanently and securely on-chain. The Lightning Network handles the everyday stuff — coffee, tips, streaming payments — instantly and for fractions of a cent.

The Basics

What is the Lightning Network?

“A second-layer protocol for instant, high-volume Bitcoin payments”

Bitcoin's base layer is intentionally slow and deliberate — every transaction is recorded permanently on thousands of nodes worldwide, confirmed roughly every 10 minutes. That's perfect for large settlements and final-value transfers, but impractical for buying a cup of coffee.

The Lightning Network solves this by allowing two parties to open a payment channel — a private ledger between them, secured by Bitcoin but settled off-chain. Payments through that channel are instant, nearly free, and don't need to be confirmed by the entire network. When the channel closes, only the final balance is recorded on the blockchain.

Channels connect to form a network, so you can pay anyone on Lightning without a direct channel — your payment routes automatically through intermediate peers.

Why It Matters

Bitcoin at the speed of life

Instant

Payments settle in milliseconds — faster than swiping a card.

💸

Near-free

Typical fees are 1–2 satoshis — fractions of a cent regardless of amount.

🔒

Bitcoin-native

No new token, no new trust model. Lightning is Bitcoin.

🕵️

More private

Lightning payments aren't recorded on the public blockchain.

Technical Deep Dive

How Lightning works

01

Open a channel

Two parties lock Bitcoin in a shared on-chain transaction, creating a payment channel. This is your Lightning "account" with that peer.

02

Send payments off-chain

Once the channel is open, both parties can send unlimited payments back and forth instantly. These transactions are NOT recorded on the blockchain — they only update the channel balance.

03

Payments route through the network

You don't need a direct channel with every person you pay. Payments automatically route through a network of connected peers — like how the internet routes data through multiple hops.

04

Close and settle on-chain

When you're done, closing the channel broadcasts the final balance to the Bitcoin blockchain. The base layer guarantees settlement — Lightning inherits Bitcoin's security.

Get Started

Choose your wallet

Start simple. Most people begin with a custodial wallet, learn the ropes, then graduate to a self-custodial option when they're ready to fully own their keys.

Key Concept

Custodial vs. non-custodial

Custodial

The wallet provider holds your Bitcoin on your behalf. Easy to use — no channel management — but you're trusting a third party.

Examples

Wallet of Satoshi, Strike, Cash App

Non-custodial

You control the keys. Your Bitcoin is yours — no third party can freeze or confiscate it. Slightly more setup required.

Examples

Phoenix, Breez, Zeus, Alby Hub

Our recommendation

Start with Wallet of Satoshi to learn Lightning without friction. Once you understand how payments work and you're holding meaningful amounts, switch to Phoenix for full self-custody. Come to the meetup — we'll walk you through the setup.
