We’re using ACINQ’s amazing Strike payment system so we recommend opening a channel to one of their nodes: https://1ml.com/node/03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f
From Wikipedia
The Lightning Network is a “Layer 2” payment protocol that operates on top of a blockchain-based cryptocurrency (like Bitcoin). It enables fast transactions between participating nodes and has been touted as a solution to the Bitcoin scalability problem. It features a peer-to-peer system for making micropayments of cryptocurrency through a network of bidirectional payment channels without delegating custody of funds. Lightning Network implementation also simplifies atomic swaps.[clarification needed]
Normal use of the Lightning Network consists of opening a payment channel by committing a funding transaction to the relevant base blockchain (Layer 1), followed by making any number of Lightning transactions that update the tentative distribution of the channel’s funds without broadcasting to the blockchain, optionally followed by closing the payment channel by broadcasting the final version of the transaction to distribute the channel’s funds.
