About Lightning Network
Lightning Network is a protocol for sending Bitcoin payments through off-chain payment channels while relying on the blockchain for security and final settlement. It is designed to reduce confirmation delays and transaction fees while keeping payments enforceable through smart-contract logic.
The site explains how two-party channels can be updated repeatedly without publishing every payment to the blockchain. Those channels can then be routed across a network of participants, enabling instant transfers with atomic settlement properties.
The project also highlights broader use cases such as micropayments and cross-chain atomic swaps, where compatible blockchains can exchange value without a trusted third party. Documentation and a paper summary are provided for readers who want the technical background.
