01:09:49 <charolastra> how closely are the wallet-cli/rpc and the deamon connected. i've noticed that the wallet blockheight is dealayed to the daemon
02:44:04 <M7918070_[m]> Does Monero support cross-chain atomic swaps, or is multisig your only option?
02:45:19 <M7918070_[m]> I found this: https://old.reddit.com/r/Monero/comments/8earbf/so_whats_the_best_way_to_do_cross_chain_atomic/?st=k4t91pas&sh=c8574f80

02:48:23 <M7918070_[m]> It's also possible to do it with an intermediary which is trusted to not be outright scammy but doesn't have to be trusted - just do escrow, but of the actual txns instead of holding the coins
03:09:35 <M7918070_[m]> A really ghetto way would be to use the private->public key function as a hash function.
03:10:57 <M7918070_[m]> Then you could do cross-chain swaps between ETH and XMR: set up a 2-of-2 multisig address in Monero, and a contract that requires the private key in Ethereum. Since you can do cross-chain swaps between (for instance) BTC and ETH, that means you can do multi-leg XMR <-> BTC swaps.
03:31:47 <bigslim[m]> whats up with the twitter feed in the GUI source? Was this ever intended to be used?
03:40:57 <gingeropolous> back in the day, like 2014, packing that kind of stuff into guis was considered .... useful? I dunno. I never understood it
03:44:51 <bigslim[m]> its calling your requested feed on your account and or slected users
03:45:09 <bigslim[m]> I dunno why anyone would ever want that specifically
04:11:38 <bigslim[m]> waz dis: https://github.com/aeonix/aeon-gui/tree/master/installers/windows
04:25:51 <gingeropolous> uh, a windows installer for the GUI
04:36:02 <bigslim[m]> is that some additional installer or is it just the source that builds the windows installer for gui?
06:50:33 <rbrunner> bigslim: Check the ReadMe. It's an InnoSetup script able to build a standalone Windows installer exe for the Monero GUI wallet.
06:51:22 <rbrunner> It came in with stoffu's code rebase from Monero and looks unmodified, so would of course not work for AEON without modifications.

16:04:01 <fullmetalScience> Hey, how is the second char of an address determined?
16:05:48 <moneromooo> By the low bits of the spend key IIRC.
16:06:36 <moneromooo> See get_account_address_as_str.
16:13:27 <immans> hello all
16:42:59 <fullmetalScience> From there, I've ended up checking the code in config::testnet, but the NETWORK_ID's provided there don't make much sense to me yet.
16:44:57 <fullmetalScience> ... or my decoder is just wrong. A testnet base58 prefix can be ... 9, A or H, right?
16:46:28 <moneromooo> I never saw H. Subaddresses maybe ?
16:47:54 <asymptotically> fullmetalScience: because of the way the base 58 encoding works, one byte can influence more than one character in the final string
16:52:15 <fullmetalScience> Given the "18" that indicates the main network, how do I get to the "4" that leads any mainnet primary address?
16:52:34 <asymptotically> don't look at the 4. decode the full base58 string and look at that instead
16:54:14 <fullmetalScience> Okay, but how is it "ensured" then that all primary addresses start with a 4? Or, how is it ensured that the entirety of the factors don't cause a different starting character?
16:55:03 <fullmetalScience> Afaiu we merge 18 + pubspend + pubview + csum
16:55:12 <fullmetalScience> concat*
16:55:17 <asymptotically> it's like going to hex, or to octal (just scarier and more upsetting)
16:56:48 <moneromooo> Binary.
16:57:06 <moneromooo> er, input is binary, output is text.
16:57:25 <moneromooo> The 18 is 0x18 IIRC. All the rest is binary appended to it.
16:57:38 <moneromooo> Keys, checksum. Possibly payment id.
16:57:57 <fullmetalScience> Okay, so the network byte is converted separately?
16:58:00 <moneromooo> The fact that the first byte is 0x18 ensures you get a 4 prefix.
16:58:05 <moneromooo> I don't think so.
16:58:31 <asymptotically> no it all happens at once. base58(0x18 || public spend key || public view key || hash of previous)
16:59:07 <asymptotically> what language are you implementing your decoder/validator in? i have a java one you're welcome to steal :)
16:59:35 <moneromooo> I have a C++ one you're welcome to copy if you abide by the BSD licence ^_^
16:59:55 <fullmetalScience> It's more about understanding the internals :)
17:00:11 <moneromooo> Maybe look at the base58 unit tests.
17:00:40 <asymptotically> you can hurt yourself on c++. just sign all of your memory away to the jvm and embrace java
17:01:42 <fullmetalScience> For example, I had thought that testnet always starts with 9. Mastering Monero confirms that. But I created a testnet wallet that starts with A
17:05:14 <asymptotically> testnet wallets always start with the byte 53, 54, or 63. you can play around with different starting bytes on https://xmr.llcoins.net/addresstests.html
17:05:30 <asymptotically> use inspect element to change the box, and make sure to enter it as hex instead of decimal
17:05:56 <moneromooo> Then Mastering Monero is wrong. 9 and A are both valid for testnet.
17:06:03 <moneromooo> Only 4 for mainnet.
17:07:11 <fullmetalScience> ... and how do we know which possibilities exist for the second char?
17:07:50 <moneromooo> It depends where the mapping starts really. To compare with real numbers for simplcity: If your keyspace is 0.5 wide, and it starts at 3.4, then all your keys will start with 3. If the keyspace starts at 3.8, ~40% will start with 3, and ~60% wil start with 4.
17:08:03 <fullmetalScience> Like, it seems for testnet (9) "t" to "z" is possible, while for testnet (A) there are other stings
17:08:16 <fullmetalScience> chars*
17:08:42 <moneromooo> You can make a good guess by encoding the keys 00.00 and ff..ff.
17:08:55 <moneromooo> That'll encompass your keyspace.
17:09:05 <fullmetalScience> Ah that's why we have like 9t - Awhatever
17:09:11 <moneromooo> Not all keys are valid in that full space, but close enough.
17:12:11 <fullmetalScience> So can we know for sure beforehand which combinations for the first to characters in the base58 encoding come up?
17:13:26 <fullmetalScience> Let's say I've seen 9t, 9u, 9v, 9w, 9z, A0, A1 so far. Is it certain that 9x or 9y also exist as possibilities? (just an example)
17:14:11 <asymptotically> you can figure them all out if you want, but imo it doesn't matter, only the bytes it represents matter
17:15:49 <fullmetalScience> Backround: The vanity address generator at moneroexamples/ doesn't allow searching for A2. I know however, that A2 is a possible address.
17:17:07 <fullmetalScience> Haven't checked its code yet, but I'd guess that would indicate it to just hold a hard-coded list of possibilities it checks against when the user makes their choice.
17:50:13 <fullmetalScience> By the way, does anyone know how to get into private testnet mode on Monerujo?
17:50:31 <fullmetalScience> Or common testnet, fwiw.
18:48:58 <camthegeek`> happy new year fellow monero'ers! :)
18:53:39 <rottensox> you're a masari mole.
18:53:42 <rottensox> get out.
