00:13:05 <WantClue[m]> thats what is in the log of the rpc 
00:13:21 <WantClue[m]> couldn't find anything that is explaining what this unwound call stack is
00:34:00 <ofrnxmr[m]> Os? And what did you do to ufw?
00:34:23 <WantClue[m]> ubuntu 22.04
00:34:56 <WantClue[m]> 127.0.0.1                  ALLOW       127.0.0.1... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/ac50a87742d081b7a9ab92116dc9208dfbc31877>)
00:35:35 <ofrnxmr[m]> Release binaries? or built from source?
00:35:47 <WantClue[m]> build from source
00:36:12 <ofrnxmr[m]> Try release or do the gitian build if trust issues
00:37:28 <WantClue[m]> https://github.com/monero-project/monero#compiling-monero-from-source I used this so I shall use the release instead ?
00:40:51 <ofrnxmr[m]> just try the 18.2.2 binaries, if those work youll need to do a gitian or a depends build
00:41:10 <WantClue[m]> mh lemme see
00:47:27 <WantClue[m]> probably need to wait one or two hours to see if this now works
00:48:03 <ofrnxmr[m]> `127.0.0.1                  ALLOW       127.0.0.1`
00:48:03 <ofrnxmr[m]> Also - i dont think this is necessary.. ? Did you add this because of some other proxy-like service? 
00:48:46 <WantClue[m]> yap
00:50:43 <WantClue[m]> just for a local ngnix
06:26:57 <Guest1153> hello alltogether
06:29:26 <Pascal123> i would like to ask for a bit help, i want to submit a share and get as error wrong hash. Which hash i ve to submit, please? i tried the blob with altered nonce and the hash result of pow, nothing works
06:31:24 <Pascal123> i would appreciate any documentation about though, so i could read through if it is some more effort to explain me
06:37:53 <moneromooo> You do not submit a hash, but a nonce.
06:38:14 <moneromooo> The hash is just a byproduct of hashing the block template with that nonce.
06:44:49 <Pascal123> hi moneromooo, does that mean i have only to submit the nonce ?
06:46:41 <Pascal123> i try to sent this: {"method":"submit","id":2,"params":{"id":"a35a9bec-2823-49ee-874b-7d7985b9c804","job_id":"142399","nonce":"01b29b0c","result":"9da610102006a2b82bf6b627324c0c2dd27d0ab07dd6d0eace56f2a52c1a4d2b7c985d520091538dcc0000004e2839e8f44ef396e228eabc828f67f24df882f7ffe847ddffbc075947662242e04a9900"}}
06:51:17 <moneromooo> I'm not familiar with the pool RPC, but IIRC xmrig has a --verbose flag which hopefully dumps that traggic.
06:51:21 <moneromooo> traffic
06:51:49 <Pascal123> i m writing on a custom miner
06:52:00 <moneromooo> I gathered :)
06:53:05 <Pascal123> by stratum protocol the blob is always 80 bytes, isnt it ?
06:56:15 <moneromooo> I'm not familiar with the pool RPC, but I doubt the blob is always 80 bytes.
06:56:36 <Pascal123> hmm ok
06:57:07 <Pascal123> so the hash should be the blob with computed nonce,or not ?
06:57:35 <moneromooo> The PoW hash ? It's the hash of the blob with embedded computed nonce.
06:57:50 <Pascal123> yes i mean the pow hash
06:58:04 <Pascal123> i have to submit the pow hash, right ?
06:58:14 <moneromooo> You do not submit a hash, but a nonce.
06:58:19 <moneromooo> The hash is just a byproduct of hashing the block template with that nonce.
06:58:40 <moneromooo> And indeed, you just posted: {"method":"submit","id":2,"params":{"id":"a35a9bec-2823-49ee-874b-7d7985b9c804","job_id":"142399","nonce":"...
06:58:43 <Pascal123> yes, i understood. but the error message says wrong hash
06:59:03 <moneromooo> Then maybe you're not calculating that nonce properly.
06:59:33 <moneromooo> Apparently a common-ish bug there is mixing up endiannesses on the hash when comparing to the target.
06:59:33 <Pascal123> "result":"9da610102006a2b82bf6b627324c0c2dd27d0ab07dd6d0eace56f2a52c1a4d2b7c985d520091538dcc0000004e2839e8f44ef396e228eabc828f67f24df882f7ffe847ddffbc075947662242e04a9900"}}
07:00:06 <Pascal123> hmm...
07:00:49 <Pascal123> ok, thank you-i suppose i ve to dive more into
07:01:11 <moneromooo> I'd first rig (ahem) your miner to always work on a known block, and check if accepts the known nonce for that block, etc.
07:01:25 <moneromooo> Decrease the number of unknowns basically.
07:01:59 <moneromooo> ie, a block from the monero chain, where you know this nonce is good for that block hashing block.
07:03:57 <Pascal123> ok
07:55:39 <Pascal123> which size has target please
07:55:53 <Pascal123> target has to be 32 bytes or 4 bytes ?
07:57:02 <moneromooo> Depends on the network difficulty. The higher the diff, the more bits will be needed to represent the target.
07:57:17 <moneromooo> 32 bits is probably not enough.
07:57:55 <moneromooo> Take a random recent monero block, count the 0s at the end of the PoW hash, multiply by 4. Gives you a rough idea.
07:59:02 <Pascal123> ok
07:59:10 <moneromooo> I tried, I count 9 zeroes. 36 bits, give or take. The next digit is a 2, there's at least one more bit.
08:00:18 <Pascal123> but the pow hash is always 32 bytes big, how i have to compare it to meet the target, please ?
08:01:32 <moneromooo> Look in monerod.
08:01:39 <moneromooo> checkhash IIRC
08:01:43 <moneromooo> check_hash IIRC
08:02:02 <Pascal123> ok, you mean monerod sourc code?
08:02:05 <moneromooo> Yes.
08:02:12 <Pascal123> ok
08:02:14 <Pascal123> ty
11:57:08 <Pascal123> fck***, the implemtation of check_hash looks terrible complicate, is there no simpler approach like checking bitcoins ?
11:57:34 <Pascal123> i meant like checking pow for bitcoins
12:01:59 <moneromooo> It should be the same system. Pick Bitcoin's if you want. Just make sure you get endianness right.
12:03:03 <moneromooo> It's just comparing two 256 bit integers really. check_hash is probably optimized with range assumptions.
12:04:27 <moneromooo> Yes, I just git grepped, look for "usual slow check", that'll be a very simple, but possibly slow, method.
12:04:30 <Pascal123> or maybe bc of asic resistance...the code looks terriblecomplicate
12:04:44 <moneromooo> Doesn't factor in.
12:04:51 <Pascal123> ah ok
12:05:01 <Pascal123> i found something to try, thank you though
12:05:05 <moneromooo> In fact, the slowness of monero's PoW hash means you can probaly get away with a slow check_hash anyway.
12:05:27 <Pascal123> hmm ok
12:30:36 <Guest6934> noob question: how does one efficiently work on a huge code base like monero?
12:31:01 <Guest6934> I'm asking because currently I'm building from source and it will probably take ~2h
12:31:07 <moneromooo> Same as all code bases. Learn the code.
12:31:21 <moneromooo> It does take time, but as yo uget to know it, you get better.
12:31:53 <moneromooo> I recommend ccache, and also building just what you need, eg make -C build/wherever game etc.
12:32:23 <moneromooo> But yes it is oomphy.
12:33:22 <Guest6934> okay thanks, I'll try to get a little more familiar with c++, cmake and how things work in general
12:55:31 <Pascal123> hey 
12:55:43 <Pascal123> could that be possible ?? Submit (Difficulty 8947) : {"method":"submit","id":2,"params":{"id":"4ef16f07-be52-4f90-ac9a-812d05cc5cbd","job_id":"143807","nonce":"000fc468","result":"009a991599a3e29e7c5368b336ef93ad3c2bfb1e81f1d7eef007a0690195a317"}}
12:56:15 <Pascal123> i get response: {"id":2,"jsonrpc":"2.0","result":null,"error":{"code":-1,"message":"Wrong hash 8d774851987ddc20f1d4ada7617c4546ff2c6fcf910aab8a6b49f18edccf6d5e 009a991599a3e29e7c5368b336ef93ad3c2bfb1e81f1d7eef007a0690195a317"}}
12:57:14 <Pascal123> for the hash i actually take the computed pow hash,is that correct ?
12:57:56 <Pascal123> difficulty 8947 looks so small to me ...
13:04:39 <Pascal123> a common question, is it necessary that i have to compute the merkle root of the new blob before submit the share ?
13:19:09 <Pascal123> i m a bit confused..if i connect to a monero pool - the server immediatly send me a response with job and not the block template
13:19:37 <Pascal123> so, if i need coinbase1 and coinbase2 i dont know how to calculate merkle tree root :(
13:19:49 <Pascal123> could someone help , please ?
13:45:35 <moneromooo> If you're mining to a pool, pools adjust their difficulty to your hash rate. Typically *much* lower than the network difficulty.
13:46:14 <moneromooo> You should not have to compute a merkle root with a pool miner. The pool software will do this.
13:46:36 <moneromooo> A pool miner just pokes a nonce into the hashing blobl and hashes I think.
13:56:42 <Pascal123> hmmmm okey..thank you very much - maybe that info helps me to get a bit further :)
14:03:13 <Pascal123> i still get result wrong hash...fck
16:16:14 <Pascal123> moneromooo, getblocktemplate command does not work on pool, i m missing something ?
16:17:31 <Pascal123> "{\"id\":2,\"jsonrpc\":\"2.0\",\"method\":\"get_block_template\",\"params\":{\"wallet_address\":\"45XMaYZXa61aTu7wCfrwmJ6kPvXt2G12JEkxsocPxfHkgk4SJmvx45e2MFuJwQT1weYJLqtGvLcuCCTCtVVzpwPaFpsvUBX\",\"reserve_size\":60}}\n"
16:19:23 <moneromooo> Yes. A pool and monerod are different things. They have different APIs.
16:21:54 <Pascal123> oooh okey...
16:22:18 <Pascal123> where i could get informations about commands for a pool ?
16:24:18 <moneromooo> Well, the world wide web usually has a fair amount of info on various things. There are tools that can search it.
16:25:08 <moneromooo> Though IIRC what monero pools call "stratum" is inspired by, but not equivalent to, the Bitcoin "stratum". So make sure you look at the monero version only.
16:25:26 <Pascal123> ok :)
16:25:38 <moneromooo> (and that, by the way, is a good keyword to search for)
16:25:48 <Pascal123> ok
16:26:13 <moneromooo> Also, I think I mentined before dumping the RPC traffic from xmrig.
16:27:43 <moneromooo> Like this: https://paste.debian.net/hidden/307bfea4/
16:27:55 <moneromooo> Definitely not monerod RPC.
16:28:20 <Pascal123> yes
16:28:23 <Pascal123> TY
16:28:42 <moneromooo> That submit was succesful btw. Guves you an example of correct RPC.
16:34:22 <Pascal123> ok
16:36:26 <Pascal123> i have to find documentation about how to subscribe to pool
16:36:30 <Pascal123> i dont find anything
17:21:11 <Guest7638> nick Pascal123
17:22:21 <Pascal123> moneromooo, i stepped on a stupid question..have i to hash the blob,or i have to hash the seed_hash ?
17:26:34 <moneromooo> You hash the hashing blob IIRC.
17:27:05 <moneromooo> If we're on about stupid things... make sure you convert the hex to binary. Happened before.
17:38:35 <Pascal123> to bytes im converting, yes i do
17:38:47 <Pascal123> hmm
18:27:07 <Pascal123> hmm... how much time it would take to resolve difficulty 1300000 with 12 cpu threads ?
