Lightning Network Channels

Architecture

Lightning Network Channels establish bidirectional payment pathways between participants, enabling off-chain transactions that settle on the underlying blockchain. These channels utilize a commitment transaction scheme, allowing for numerous transfers without requiring each to be recorded directly on the blockchain, thereby significantly increasing transaction throughput. The channel’s capacity is determined by the initial funding amount locked in a multi-signature contract, and updates to the balance are exchanged between parties. Channel topology dictates the network’s routing capabilities, enabling payments to traverse multiple channels to reach a destination.
