06:52:46 <usamat> Hello.
06:52:47 <usamat> "rct_signatures": {
06:52:47 <usamat>     "type": 5, ....
06:52:48 <usamat> I know that the MGs and CLSAG differ between type 4 and 5, but when building a txn, how de we determine which type to use?
10:02:21 <wowario[m]> usamat: https://github.com/monero-project/monero/blob/cb70ae9450b6887a046ef962abe73f3e64787ae2/src/ringct/rctTypes.h#L259
10:56:22 <ErCiccione[m]> Please help me with these definitions, so we can merge the PR: https://github.com/monero-project/monero-site/pull/1448#issuecomment-772419506
11:56:21 <tmsufzhlf> Why are you here? For the tech? Then you should be off at Zcash instead of trying to con newbies into a coin that doesn't work. For the money? If you put your money in BTC or ETH you would have been better off. For the magical crypto friends? Monero leadership laughs from losers like that. Find yourself more healthy realationships that don't laugh at you when they steal your money.
14:48:47 <peach34> Hi guys
14:49:03 <peach34> If I have a curve point X = A + B
14:49:43 <peach34> where we're using a common basepoint for each curve point
14:49:52 <peach34> ie X=xG
14:50:20 <peach34> it's computationally infeasible to compute x, even with A and B right
14:51:11 <peach34> it surely doesn't matter that you know an additive combination that gets you X
14:52:35 <moneromooo> Correct, from the argument that if you just have X=xG, you can trivially calculate Y=X-1, ending up in your original case.
14:52:47 <moneromooo> (A=1, B=X-1)
14:54:53 <peach34> But you have no way of knowing b and a even for A=1, B=X-1 right
14:55:54 <luigi1111> of course
14:55:59 <peach34> Yeah just checking lol
14:56:01 <moneromooo> Depends. 1 is not a valid point, but let's say G. Then a would be 1 :P
14:56:31 <peach34> Yeah I mean apart from silly choices :P
14:57:00 <peach34> so to prove knowledge of x, you could equivalently sign with (a+b)
14:57:16 <peach34> because x = a+b
17:08:24 <peach34> guys in the code i see a 'global output index'
17:08:35 <peach34> Is this still just the per denomination index?
17:08:51 <peach34> or is it the absolute index of the output over all the denominations possible
17:09:00 <hyc> should be absolute index
17:09:15 <hyc> there are no more denominations
17:10:06 <peach34> hyc since when?
17:10:17 <hyc> since ringCT was enabled
17:16:14 <peach34> hyc thanks. Are there any calls I can make to get a global output index for say a given stealth address?
17:18:04 <hyc> probably
17:18:14 <hyc> dunno the func name off top of my head
17:18:53 <hyc> for a given txn ID that is
17:19:18 <peach34> No I meant per output
17:19:38 <peach34> Do all outputs in a given tx have the same global output index?
17:19:45 <luigi1111> nah there's no index like that
17:19:51 <luigi1111> you'd have to walk it
17:19:58 <hyc> read the schema description here https://github.com/monero-project/monero/blob/master/src/blockchain_db/lmdb/db_lmdb.cpp#L189
17:20:04 <peach34> thank you
17:21:23 <moneromooo> Per amount, rct outputs use amount 0.
17:22:04 <hyc> moneromooo: are you available for -research meeting?
17:22:31 <moneromooo> Sure
17:22:52 <hyc> they pinged you
