Up to date? 14:11 < HelloShitty> https://buildmedia.readthedocs.org/media/pdf/lightning/latest/lightning.pdf 14:12 < HelloShitty> Apparently is some doc written by Decker and Rusty somewhere in 2019 14:12 < m-schmoock> They have been updated pretty recently 14:12 < HelloShitty> oh, even that one I just mentioned? 14:12 < m-schmoock> 2020-11-17 14:13 < m-schmoock> the doc/BACKUP.md 14:13 < HelloShitty> ok 14:13 < m-schmoock> and 2020-11-26 for the plugin repo backup/README.md 14:13 < m-schmoock> I dont know whats with the PDF 14:14 < m-schmoock> That seems outdated 14:15 < HelloShitty> ok, thank you 14:15 < HelloShitty> I'm stick to the github ocs 14:15 < HelloShitty> s/ocs/docs 14:16 < HelloShitty> m-schmoock: backing up is good enough to make sure we don't lose funds? 14:16 < HelloShitty> Or is this still uncertain? 14:16 < m-schmoock> Thats the point of doing a proper backup :D 14:17 < m-schmoock> You could still loose funds in other ways than data loss. 14:17 < m-schmoock> backup only covers data loss 14:17 < m-schmoock> If uncertain, try it on testnet first 14:17 < m-schmoock> For me the plugin does its job 14:20 < HelloShitty> you mean that it does it's job regarding data loss, right? 14:21 < m-schmoock> yes 14:21 < HelloShitty> But other than trying to cheat, what other ways there are to lose funds? 14:21 < m-schmoock> getting hacked 14:21 < HelloShitty> And by cheating I mean trying to send some older off-chain transaction onto the on-chain blockchain 14:22 < HelloShitty> ah ok 14:22 -!- kristapsk [~KK@gateway/tor-sasl/kristapsk] has quit [Remote host closed the connection] 14:22 < m-schmoock> cheating should not be possible in LN otherwise theres a protocol bug 14:23 < m-schmoock> if your node is offline while you are being force closed, and your node stays offline until the end of the retailiation window, you can loose funds 14:23 < HelloShitty> ok, so if I, by mistake (don't ask me how) try to send some older off-chain transaction to the online blockchain 14:23 < HelloShitty> I'll be penalized, right? 14:24 < HelloShitty> That's already covered, yes? 14:24 < m-schmoock> yes, if the node thats being cheated is online it will respond by taking all the funds (currently). This may change in the future 14:24 < HelloShitty> ok 14:25 < m-schmoock> if its offline, and keeps offline, your funds can (not will) be stolen 14:25 < HelloShitty> wait. There are 2 scenarios for this 14:25 < HelloShitty> me trying to send an oler transaction, to online blockchain 14:25 < HelloShitty> and 14:26 < HelloShitty> someone trying to send some older transaction to the online chain 14:26 < HelloShitty> I mean, this is not yet very clear to me, sorry for the questions 14:27 < m-schmoock> if someone else sends an older state, your node will react by taking all the funds 14:27 < HelloShitty> but if I open a channel with friend A, can this friend A try to cheat me? 14:27 < HelloShitty> ok 14:27 < m-schmoock> if you send an older state the other node will do this (very likely) 14:27 < HelloShitty> ok 14:27 < m-schmoock> if the 'attacked' node is offline and stays offline for the retailiation window timeframe, than funds can be lost 14:28 < HelloShitty> ok 14:28 < HelloShitty> I unerstand better that way 14:28 < HelloShitty> There are many technical terms I'm not familiarized with yet 14:28 < m-schmoock> HelloShitty: what we discovered that active cheating attacks are very rare but people using outdated backups leading to the same result are more often :D 14:29 < HelloShitty> yeah, I was just told that by someone from bitcointalk 14:29 < m-schmoock> If you have backup plugin working and setup properly (external network mount, hsm_secret backup, ...) you should always be able to recover correctly 14:29 < HelloShitty> yeah 14:29 < HelloShitty> That's what I want to read about 14:30 < HelloShitty> how data is stored and how is it backedup 14:30 < HelloShitty> I need to understand the very basics to know what I am doing when using a backup 14:32 < m-schmoock> im going to sleep ... gn8 14:36 < HelloShitty> thank you m-schmoock 14:59 -!- MasterdonX [~masterdon@45.9.249.244] has joined #c-lightning 15:08 -!- belcher [~belcher@unaffiliated/belcher] has quit [Quit: Leaving] 15:09 -!- belcher [~belcher@unaffiliated/belcher] has joined #c-lightning 17:23 -!- DeanGuss [~dean@gateway/tor-sasl/deanguss] has quit [Ping timeout: 240 seconds] 17:24 -!- Ademan [~ademan@47.185.102.158] has quit [Ping timeout: 264 seconds] 17:36 -!- vasild [~vd@gateway/tor-sasl/vasild] has quit [Disconnected by services] 17:36 -!- vasild_ [~vd@gateway/tor-sasl/vasild] has joined #c-lightning 17:36 -!- vasild_ is now known as vasild 18:09 -!- DeanGuss [~dean@gateway/tor-sasl/deanguss] has joined #c-lightning 18:27 -!- blockstream_bot [blockstrea@gateway/shell/sameroom/x-grtgkzfemgwjcvcq] has left #c-lightning [] 18:27 -!- blockstream_bot [blockstrea@gateway/shell/sameroom/x-grtgkzfemgwjcvcq] has joined #c-lightning 19:42 -!- az0re [~az0re@gateway/tor-sasl/az0re] has joined #c-lightning 23:33 -!- az0re [~az0re@gateway/tor-sasl/az0re] has quit [Remote host closed the connection] 23:35 -!- az0re [~az0re@gateway/tor-sasl/az0re] has joined #c-lightning 23:56 -!- bitdex [~bitdex@gateway/tor-sasl/bitdex] has quit [Remote host closed the connection] 23:57 -!- bitdex [~bitdex@gateway/tor-sasl/bitdex] has joined #c-lightning --- Log closed Tue Dec 29 00:01:01 2020
