Lightning & L2

Faster, cheaper payments built on top of Bitcoin.

• Lightning Network

  Bitcoin's fast lane: instant, near-free payments that settle up on-chain later.

• Payment channels

  Two people lock bitcoin together, trade instant balance updates, and settle on-chain once.

• Lightning invoices

  A one-time payment request — scan it, pay it, done in a second.

• Routing

  How a Lightning payment finds a path through strangers without trusting any of them.

• Liquidity

  Which direction money can move through a Lightning channel, and how much of it.

• Lightning vs on-chain

  Cash register or vault: pick the layer that matches the payment.

• Layer 2

  Systems built on top of Bitcoin that trade some trust for speed or features.

• Liquid

  A faster, more private side network for bitcoin, run by a group of companies you trust.
