Hi! A couple questions about the use of sequence numbers in lightning.
Please forgive me if these are somewhat rudimentary.
1) Can someone better outline what the race conditions are? It seems
certain things time out w.r.t. the bitcoin blockchain height, which seems
negative with respect to censorship vulnerability. How is this addressed?
Section 9.5 of the paper seems unsatisfactory.
2) Using sequence numbers to select the right transaction to include is
good, but it would seem to leak information about how many LN transactions
took place, which could then make it meterable by external parties. (eg, a
miner could make the fee for settling proportional to it). Perhaps
incrementing by a random amount would alleviate the ability to reliably
meter. Maybe it is good that this can be metered?
Cheers,
Jeremy
