 66 2017-09-09T09:10:53  <meshcollider> There's no support for BIP 39 in core currently is there
 67 2017-09-09T09:11:49  <sipa> no
 68 2017-09-09T09:12:27  <meshcollider> #11085 is adding ability to set a new HD seed using a WIF private key, would there be any reason not to take that further and allow setting a 512 bit seed or even mnemonic itself?

 74 2017-09-09T09:50:05  <gmaxwell> meshcollider: bip39 is a bad spec, disavowed by some of its authors even. Among other issues it has no facilities for versioning, which is a critical flaw.
 75 2017-09-09T09:51:44  *** promag has joined #bitcoin-core-dev
 76 2017-09-09T09:55:33  <meshcollider> mhm true, but its pretty widely supported in hardware wallets and online wallets for backups so even if we didn't add mnemonic support itself, wouldn't it be useful to be able to set any seed for an HD wallet if you wanted to? Not just using a WIF private key?
 77 2017-09-09T09:56:10  <gmaxwell> doesn't make any sense.
 78 2017-09-09T09:56:10  *** promag has quit IRC
 79 2017-09-09T09:56:15  <gmaxwell> you can import indivigual keys
 80 2017-09-09T09:56:26  <gmaxwell> but just having the same seed wouldn't result in the same derrived keys
 81 2017-09-09T09:56:36  <gmaxwell> unless the feature set and style were exactly the same.
 82 2017-09-09T09:57:18  <gmaxwell> The whole idea of compatibly imported keys is wrongheaded-- at least in a world where all wallets don't have exactly the same functionality-- and can result in funds loss.
 83 2017-09-09T09:57:35  *** chjj has quit IRC
 84 2017-09-09T09:57:44  <meshcollider> I mean, most support bip 32, 39 and 44, so if you imported the 512 bit seed generated from a mnemonic from bip 39, using bip 32 to generate master key, you'd have all the same keys?
 85 2017-09-09T09:58:18  <meshcollider> as long as they support the same seed -> master key in bip32 and tree structure in bip44
 86 2017-09-09T09:58:37  <gmaxwell> Which we will not, because it's insecure if key export is possible.
 87 2017-09-09T10:00:02  <meshcollider> not sure what you mean sorry?
 88 2017-09-09T10:00:04  <gmaxwell> and again, not actually compatible because.. unversioned.. how do you know if the key is using segwit or not.. p2sh or not.
 89 2017-09-09T10:00:12  <meshcollider> key export is possible currently with dumpwallet?
 90 2017-09-09T10:00:40  <gmaxwell> meshcollider: bip 44 forces public derrivation, if you give someone one private key and they find out your extended public key they can derrive all your private keys.
 91 2017-09-09T10:01:26  <gmaxwell> BIP44 basically violates bip32 by applying public derrivation to all cases, it should only be used in cases where export is not permitted;  which is plausable for hardware wallets.
 92 2017-09-09T10:02:45  <meshcollider> ohhh you mean no to adding bip 44 support, not importing arbitrary seeds
 93 2017-09-09T10:02:46  *** fydel has quit IRC
 94 2017-09-09T10:03:03  <meshcollider> Yeah good point, fair enough then it would be pretty useless 👍
 95 2017-09-09T10:03:35  <meshcollider> I was only thinking about the security of importing the seed, not about bip44 itself hence my confusion
 96 2017-09-09T10:03:42  *** fydel has joined #bitcoin-core-dev
 97 2017-09-09T10:03:43  <gmaxwell> at some point we might support wallets which have export disabled, e.g. wallets with a public derrivation of whatever path, but it should be seperate.
 98 2017-09-09T10:03:53  <gmaxwell> with multiwallet thats more reasonable.

165 2017-09-09T18:21:13  <bane5000> Hey guys, was thinking about running a bitcoin core p2p only headless server on debian. Just had a couple of questions regarding the online documentation... first of all, do you recommend running this as root? Would it be wiser to run the daemon as a separate user/group?
166 2017-09-09T18:22:15  <bane5000> Also, I know how to operate a firewall, with that being said, does the p2p function require upnp? Would i be safe to turn it off and just forward incoming connections on port 8333 (or whichever port it is) to the server?
167 2017-09-09T18:22:17  <bane5000> Thanks guys :)
168 2017-09-09T18:25:30  <sipa> bane5000: no need to run as root, forwarding 8333 is perfectly fine but you'll need to configure your external ip address (-externalip=IP on cmdline, or externalip=IP in bitcoin.conf)
169 2017-09-09T18:27:34  <bane5000> sipa: Fantastic! I appreciate the information. Also, upon compilation, i just issue ./configure --disable-wallet (if i remember correctly?)
