((("payment channel", id="ix_07_payment_channels-asciidoc0", range="startofrange")))In this chapter we will dive into payment channels and see how they are constructed. We will start with Alice's node opening a channel to Bob's node, building on the examples presented in the beginning of this book.
The messages exchanged by Alice and Bob's nodes are defined in https://github.com/lightningnetwork/lightning-rfc/blob/master/02-peer-protocol.md["BOLT #2: Peer Protocol for Channel Management"]. The transactions created by Alice and Bob's nodes are defined in https://github.com/lightningnetwork/lightning-rfc/blob/master/03-transactions.md["BOLT #3: Bitcoin Transaction and Script Formats"]. In this chapter we are focusing on the "Channel open and close" and "Channel state machine" parts of the Lightning protocol architecture, highlighted by a double outline in the center (peer-to-peer layer) of <<LN_protocol_channel_highlight>>.
