On the Lifecycle of a Lightning Network Payment Channel

The Bitcoin Lightning Network, launched in 2018, serves as a layer 2 scaling solution for Bitcoin. The Lightning Network allows users to establish channels between each other and subsequently exchange off-chain payments. Together, these channels form a network that facilitates payments between parties even if they do not have a channel in common.

Non-Atomic Payment Splitting in Channel Networks.

, 2023
Off-chain channel networks are one of the most promising technologies for dealing with blockchain scalability and delayed finality issues. Parties connected within such networks can send coins to each other without interacting with the blockchain. Moreover, these payments can be "routed" over the network.
