Chapter overview:
* explains the channel graph, and how it's modified+verified
Relevant questions to answer:
* Gossip announcements:
* How does a peer announce a new channel to the network?
* How do nodes verify a channel announcement? Why should they verify one in the first place?
* How does a node control _how_ a payment is routed through its channel?
* What knobs exist for a node to set in their channel updates?
* How often are channel updates sent?
* How does a node update its node in the channel graph? Do we we need to verify this?
* How quickly does an update propagate?
* What are "zombie" channels? Why do they matter?
* Channel graph syncing:
* What are the various ways a node can sync the channel graph?
* Which is the most efficient?
* What is the "gossip query" system?
* Does a node need to keep up with all gossip updates? Does this change if they're a routing node or mobile client?
* Protocol Extensions via Feature Bits and TLV:
* How can the channel graph be upgraded using feature bits and TLV fields?
* How does a receiver signal that they can accept MPP/AMP payments?
