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?
