The Lightning Network (LN) is a network that operates as a second layer on top of Bitcoin. Here users can make payment to each other without the necessity of publishing a transaction to the Bitcoin blockchain for each payment.
Before LN transactions can be made, a payment channel is opened, say among Alice and Bob. A payment channel between Alice and Bob has a fixed amount, which was funded by both of them respectively, so transactions can be moved almost instantly from Alice to Bob numerous times.
