- 1.What exactly is the negative impact of a routing failure?
- 2.How might payments get stuck/unstuck due to a routing failure?
- 3.What kinds of routing failures are there and are some more severe than others?"
- 4.How do watchtowers work with non-advertised channels when part of the graph is not known?
- 5.Is the Lightning routing problem NP-hard?
- 1.On the base layer, the quality of the nodes you connect to is largely irrelevant provided they are an honest peer. How does this differ in Lightning when opening a channel to a peer?
- 2.What practical measures can nodes wishing to route on Lightning take to improve their success? Does this cause issues for new entrants?
- 1.How do we combine two partial onions?
- 2.When and why are ephemeral keys rotated? What would change if ephemeral keys were fully generated by the sender?
- 1.What privacy tradeoffs do trampoline payments have? How can they be mitigated?
- 2.Can trampoline payments be combined with atomic multi-path payments to mitigate privacy issues?
- 3.How do trampoline and rendezvous routing differ? Why would you use one or the other?
- 1.What is the difference between MPP and AMP payment splitting?
- 2.What are the advantages and disadvantages of multipath routing?
- 3.What problems could arise if a node participates in multiple paths of a multi-path payment?
- 1.What advantages do blinded routes offer over rendezvous onions? Do they have any drawbacks compared to rendezvous?
- 2.Blinded routes over-estimate sender fees and time locks to provide better receiver privacy. Discuss this trade-off.
- 3.Routing strategies such as route blinding, rendezvous and trampoline all add extra information to routing onions. Does this reduce privacy?
- 1.How can just-in-time routing help with routing payments?
- 2.How can a griefing attack affect routing nodes and what are possible counter measures?
