Lightning Network
Protocol
Fast Bitcoin payments using off chain channels.
The Lightning Network enables fast, low cost Bitcoin payments by moving most activity off chain. Two parties open a channel on the base chain, update balances with signed messages, and settle to Bitcoin when they close the channel. Multi hop routing lets payments travel across the network without trust in intermediaries. To use Lightning, pick a trusted wallet and learn how invoices, channels, and backups work. Start with small amounts, watch fees for opening and closing channels, and keep good backups to avoid loss if a device fails.
