 80 2018-11-03T07:30:49  <provoostenator> sipa thanks for the meeting ping. It's on my calendar now, but couldn't make it. ryanofsky: glad to hear "[found by?] sjors bugs" are a thing :-)
 81 2018-11-03T07:40:50  <provoostenator> gwillen: I'll take your offline signing GUI for a spin. A WIP PR seems a good way to get more feedback and make sure this work isn't forgotten if you suddenly decide to retire on a beach.
 82 2018-11-03T07:44:11  <provoostenator> I'm thinking of adding a RPC utility function "deriveaddress" which takes a descriptor and spits out an address. That way you don't need a watch-only wallet if all you need is to generate a fresh address. Can probably reuse code from scantxoutset.

 90 2018-11-03T08:10:19  <sipa> provoostenator: i'm thinking there is probably enough that can be done with psbt and descriptors that can be put in a separate utility
 91 2018-11-03T08:10:24  <provoostenator> That said, a slightly more ambitious version of the above command - combined with an address index - could give you the next available address in a range.
 92 2018-11-03T08:10:39  * sipa hates address indexes
 93 2018-11-03T08:11:08  <sipa> anything that requires a full blockchain is imho not worth spending time on
 94 2018-11-03T08:11:26  <provoostenator> Tend to agree on address indexes being total overkill. It might be better to use a wallet at that point.
 95 2018-11-03T08:11:32  <sipa> yes.
 96 2018-11-03T08:11:36  <sipa> that's what they're for
 97 2018-11-03T08:11:56  <provoostenator> It's nice to have an ephemeral wallet though, which would need an address index.
 98 2018-11-03T08:12:01  <provoostenator> (or be slow)
 99 2018-11-03T08:12:26  <sipa> i don't see why; in general making a backup of a file isn't hard
100 2018-11-03T08:12:51  <sipa> it's nice to know you can *recover* your money with a short string as an assurance; but there's not reason why that can't be slow
101 2018-11-03T08:12:54  <provoostenator> Plausible deniability. Memorize 24 words, type them in plus a deriviation path.
102 2018-11-03T08:13:16  <sipa> and give up your privacy to whoever is running the index service
103 2018-11-03T08:13:25  <provoostenator> James Bond is not going to sit around for hours waiting for a rescan, but I agree it's probably fine in more normal cases :-)
104 2018-11-03T08:13:34  <provoostenator> It would be your own node.
105 2018-11-03T08:13:49  <provoostenator> Plausible deniability in this case means having a node, maybe with some coins, but not all your coins.
106 2018-11-03T08:14:09  <sipa> i don't believe long term everyone having a fully indexed archival node is interesting or reasonable
107 2018-11-03T08:14:47  <provoostenator> Right, it wouldn't be interesting for everyone, these indexes are optional for that reason.
108 2018-11-03T08:14:52  <sipa> with bip157 it's also much less needed
109 2018-11-03T08:15:07  <sipa> (it's still slow, but several times faster to rescan)
110 2018-11-03T08:15:20  <sipa> and outsourcable
111 2018-11-03T08:15:43  <provoostenator> BIP157 does make sense as a faster-enough alternative to an address index for the above use case.
112 2018-11-03T08:17:29  <sipa> it's not quite the same, but as i said, i think "short phrase to access your coins" isn't a reasonable normal use case if you care about privacy and resource costs
113 2018-11-03T08:17:30  <provoostenator> But back to the seperate utility. I imagine there's often things that need wallet and or blockchain context. But since code can be reused between binaries, that doesn't have to be a show stopper.
114 2018-11-03T08:17:52  <sipa> sure it'd be built from the same source code
115 2018-11-03T08:18:16  <sipa> like bitcoin-tx
116 2018-11-03T08:20:10  <provoostenator> Adding psbt and descriptor to support to bitcoin-tx makes sense to me. A generateaddress seems a bit out of scope for that though?
117 2018-11-03T08:20:35  <sipa> well bitcoin-tx is really designed to operate on transactions
118 2018-11-03T08:20:49  <sipa> all its commands are things that modify transactions
119 2018-11-03T08:21:15  <sipa> perhaps psbt can be included
120 2018-11-03T08:21:55  <sipa> but i think something more traditional does make sense too, where you have a tool that exactly mirrors bitcoin-cli like usage
121 2018-11-03T08:22:10  <sipa> except it doesn't invoke a bitcoind but does everything locally
122 2018-11-03T08:23:47  <provoostenator> Right, similar to the offline wallet tool in 13926
123 2018-11-03T08:24:20  <sipa> right
124 2018-11-03T08:24:20  <provoostenator> Maybe just call it bitcoin-tool?
125 2018-11-03T08:24:24  <sipa> hah
126 2018-11-03T08:26:26  <provoostenator> RPC does have the benefit over being accessible over TCP though, so e.g. a web server can use those utility methods. Another approach would be to make those utilities easier to package in libraries.
127 2018-11-03T08:38:48  <luke-jr> provoostenator: just make encrypted backups :x
128 2018-11-03T08:40:22  <provoostenator> luke-jr: that was a great idea until forced decryption became a thing.
129 2018-11-03T08:40:51  <luke-jr> no different from forced 24 words
