I think having the recommened value being the default, while allowing the receiver to specify their preferred value is a sound route 16:21 -lightningrfc:#lightning-dev- [lightning-rfc] rustyrussell pushed 1 new commit to master: https://git.io/vdKG9 16:21 -lightningrfc:#lightning-dev- lightning-rfc/master b09e119 Rusty Russell: BOLT 11: depending in -> depending on.... 16:24 < rusty> roasbeef: OK, so to be *absolutely* clear. We are going to use the BOLT11 'c' value (or default of TBA if unknown/unspec) plus shadow route for final CTLV. For previous hops, we're going to use the *outgoing* channel's cltv_delta value as the minimum across that node. 16:24 * roasbeef gives a thumnbs up in meatspace 16:24 <+roasbeef> i have that later portion coded, updating bolt11 stuff in a new branch 16:25 <+roasbeef> #253 will need to be updated slightly to say "we're using the default" or "the receiver wants a value of N" I beleive 16:26 < rusty> roasbeef: sounds like we have consensus. I'll rewrite #253. We should use the same default number (9 seems like the default default unless you come up with better) for BOLT11 (if unspecified) and for the spec (if unknown). 16:27 <+roasbeef> if unknown? 16:28 < rusty> Non-BOLT11 payment? 16:28 <+roasbeef> ahh, yeh that makes sense 16:28 <+roasbeef> lehdoit 16:28 < rusty> Since shadow route is recommended, it doesn't really matter... OK.
