character I cannot remember offhand 03:11 < ZmnSCPxj> Rompert, in most decent AMP plans, it is needed for payee to receive all sub-payments before they can claim any of them 03:11 < ZmnSCPxj> and once they claim a sub-payment, they have incentive, to claim all payments 03:11 < ZmnSCPxj> hence atomic 03:12 < ZmnSCPxj> so if a sub-payment gets stuck due to total node failure (as opposed to temporary node failure or channel-level failure), it is OK, either the payee can get all or none 03:13 < ZmnSCPxj> (even most total node failures are detectable, only undetectable, is if the node forwarded, then died, then a downstream node or payee sent success/fail to dead node) 03:13 -!- ZmnSCPxj [9258463b@gateway/web/freenode/ip.146.88.70.59] has quit [Client Quit] 03:18 -!- ZmnSCPxj [9258463b@gateway/web/freenode/ip.146.88.70.59] has joined #lightning-dev 03:18 < ZmnSCPxj> Good morning rompert again, I was thinking a little more your scenario 03:19 < ZmnSCPxj> Of note, we cannot get confirmation that payee received sub-payment, until all sub-payments reach payee (and entire payment is made) 03:19 < ZmnSCPxj> But AMP will actually help resilience in this case (if we can define a good AMP design that has proof-of-payment) 03:21 < ZmnSCPxj> If we split into two paths, consider the case, where on one path, a hop node dies after forwarding but before success/fail 03:21 < ZmnSCPxj> But on other path, no hop nodes die and we can get success 03:21 < ZmnSCPxj> in that case, we can safely get the proof-of-payment (if using my HD+SS-based AMP) 03:21 < ZmnSCPxj> and if second path fails, we can retry it repeatedly until the invoice times out 03:22 < ZmnSCPxj> and once the invoice times out and the second path still fails, we know that the first path (which has error) cannot be redeemed by payee 03:22 < ZmnSCPxj> since the first path needs some knowledge we provide in the second path 03:22 < ZmnSCPxj> in order to claim 03:22 < ZmnSCPxj> so AMP is definitely an improvement 03:23 < ZmnSCPxj> issue is that current HTLC is not amenable to multipath+proof-of-payment+path-decorrelation 03:24 < ZmnSCPxj> Need SS, which needs Bellare-Neven + updated BOLT +

19:32 < mryandao> if i understood correctly, the privacy only applies to payment details, not the existence of nodes/channels 19:33 < mlz> if my node is private and you're not connected to me, how do you know ? 19:33 < mryandao> mlz: sure, then no-one can use your node as an intermediary for payment routing 19:33 < mlz> that is fine 19:33 < mryandao> but LN does support payment routing, so there has to be public nodes 19:34 < mlz> sure you can see some nodes on the explorer but you don't get to know *every* node 19:35 < mryandao> that's fine, its sufficient to know the topology of public nodes for source-based routing 19:35 < mlz> what's "source-based" routing? 19:36 < mryandao> a payment route that is pre-determined at the source node? 19:36 < mlz> not sure what that means 19:36 < mlz> you can see nodes having channels with other nodes but you have no sure way they can route your payments 19:41 < mlz> it's because of the privacy issue we don't get to know who/what if they spend their money on and that can be used as liquidity to route other payments 19:46 < roasbeef> ln_byz: connect out to a node...parse the messages 19:47 < roasbeef> can use bits of lnd packages to parse, etc 19:49 < mryandao> mlz: you can still do source-based routing without knowing the channel states, by optimisitcally requesting them to route payments on behalf; if it fails, you just try a different route. 19:57 -!- jb55 [~jb55@S010660e327dca171.vc.shawcable.net] has quit [Quit: WeeChat 2.0] 19:57 -!- Chris_Stewart_5 [chris@gateway/vpn/privateinternetaccess/chrisstewart5/x-62865615] has joined #lightning-dev 19:58 < mlz> mryandao, what's "source-based" routing?
