20:45:25 <sech1> moneromooo I have a question about https://github.com/monero-project/monero/blob/master/src/cryptonote_core/cryptonote_tx_utils.cpp#L79 which is called from get_block_template RPC. It generates one-time keypair txkey and txkey.sec can be used to spend the miner reward. So does it mean remote node knows it and can spend it too?
21:04:35 <UkoeHB> isn't that just the transaction public key? you also need the recipient's private spend key to spend the output
21:07:57 <sech1> private spend key is used to restore txkey.sec which is then used to spend the output
21:08:08 <sech1> if you know txkey.sec, you don't need anything else
21:08:38 <sech1> transaction public key = txkey.pub
21:24:21 <UkoeHB> transaction public key and one-time address are different things; you need one-time address to spend an output, and by convention it is made from tx pub key + view/spend priv keys
21:27:58 <UkoeHB> here is the one-time address being constructed from pub spend key and 'derivation' (tx priv key & pub view key) https://github.com/monero-project/monero/blob/ab7df49331a4356d7102119ede036b0d73295905/src/cryptonote_core/cryptonote_tx_utils.cpp#L150
21:34:08 <sech1> ok, I'm reading chapter 4.2 of https://www.getmonero.org/library/Zero-to-Monero-2-0-0.pdf and I can't understand what is txkey.sec there
21:34:25 <sech1> it's used in generate_key_derivation
21:36:17 <sech1> it seems txkey.sec is this random number r
21:47:19 <sech1> yes, txkey.sec = r, txkey.pub = rG, derivation = Hn(rK(v,B)*G, out_eph_public_key = K0 in that code
21:47:30 <sech1> so txkey.sec is just r and can't be used to spend output
21:48:36 <selsta> sech1: are you asking because of https://twitter.com/jtgrassie/status/1404530663303307267? ?
21:48:57 <sech1> lol yes
21:49:09 <sech1> I'm implementing all this stuff in xmrig
21:50:41 <sech1> didn't see that tweet before
22:03:03 <UkoeHB> yep sounds right to me

22:23:03 <xmrscott> (Or luigi, sorry for spacing on you)

22:38:06 <rehrar> oops. Apologies.
22:38:31 <selsta> xmrscott: fwiw they already approved it for #monero-markets
22:38:41 <selsta> not sure if you need permission for every channel separately
