1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Ħ [HODL] Version 5.0.0 was borked - urgent upgrade to version 6.0.0 on: November 23, 2019, 04:07:39 PM
The optiminer hodlcoin pool has been upgraded to the latest version 6.0.0 and is working again.

Happy mining and holding!

http://hodl.optiminer.pl

Code:
hodlminer.exe -o stratum+tcp://hodl.optiminer.pl:5555 -u HODLADDR -p x

./hodlminer -o stratum+tcp://hodl.optiminer.pl:5555 -u HODLADDR -p x

Been using Optiminer for various coins for nearly a year now and I'm happy with it.

Any possibility of Optiminer AMD Linux support for Equihash 210_9 ?

I don't know if supporting Equihash 210_9 would require a major amount of work or if it can be accomplished with just a few simple tweaks.


Which coins use 210/9 as equihash params?

Under what license is this miner distributed?

Is the source available? It seems to use GPLed code, so I would expect it to be.

Hi there,
Can you be more specific which code under GPL you think I am using?  The only external libraries I use and link at the moment are the boost library and the g++/mingw64 runtimes. Well and OpenCL of cause. I hope I am not wrong here, so if you found somethink I use that I am not allowed to I will remove it immidiately.  I wrote most of this from scratch - don't even have the external equihashverify code from node code in here. Beeing a bit more specific could help clarifying this.


Ah okay, so you claim it to be GPL code-free. That's fine. I do not have the code available so I cannot say much about that. But for parts of the opencl kernel it's obvious that you started from GPLed code and modified it from there (probably a lot). Just try this: https://www.google.com/search?q=%22occupy+the+high+32+bits+of+the+second+ulong+word%22

If that's still covered by the GPL or not I don't know.

Hey guys,
here is smth how the dev fee working in that pretty miner:

Optiminer-Equihash is transmitting packages to 88.99.30.25 through X11 port (TCP based) 6060.
http://88.99.30.25/ source is HOdl mining pool with links to Optiminer github repos.

So it looks like a hidden HOdl miner (CPU) inside the optiminer (you can found the hodlminer-wolf inside optiminer's github repo)

Proofs: just open the Wireshark and catch the X11 packages while running miner.


That's wrong. As written on the miner's web page the miner will use 1% of the GPU time to mine for supporting the developer (unless the --nodevfee option is used in which case the devs are not payed anything but the miner runs slower: a classic lose-lose situation). To submit the shares done for the dev fee work, the miner connects to the host proxy.optiminer.pl. Make sure that this address is open in the firewall (otherwise the miner falls back to the 'nodevfee' mode).

Yes, currently hodl.optiminer.pl and proxy.optiminer.pl both resolve to the same ip address. This is simply because I run the dev fee server and the hodlcoin mining pool on the same server. The equihash miner does no hodl mining, these are separate processes.

(If you want to do hodl mining on your CPU in parallel to GPU mining you can of course do that if you want -- just follow the instructions at http://hodl.optiminer.pl Smiley )

New version's setup is now released thanks to ghobson!

Download it @ http://hodlcoin.com/#wallet

It's looking good!

Does anyone know which pools nicehash uses to aggreate their hasing power on ? I don't know, and want to buy a contract for hashing power on suprnova.cc, but they don't participate.

Is there a current list of HODL mining pools up to date that don't 404?


hodl.optiminer.pl works with nicehash

FYI, the hodl.optiminer.pl mining pool is now compatible with nicehash!

Looking for HOdl pool instructions

I used to mine on suprnova.cc (can't remember what coin or if I stayed mining there very long) and I can still log in, but I can't reset my pin. My attempts for support never get reply's from the pool operators. Mining solo isn't working.

I suppose I will need to boot a Linux box and get programming. I have setup masternodes for other coins in the past. I expect it will take some messing about but I should be able to get a HOdl pool working. I am looking for any instructions on how to start a HOdl pool. If anyone has this information please reply or message me.

Try http://hodl.optiminer.pl No registration required. Just start mining.

Nice! I can't see no payment yet?!? But I also noticed that my address suddenly disappeared from the list and came back after I restarted the miner. Started from 0 again. Maybe something got lost? Well, let's wait for the next block.  Smiley   

Payouts happen normally with the next mined block. The list on the main page only shows currently active miner. Note that there is a search box on top of the page where you can enter your address and it will show you all the balance details.

Yes, the average is over the last N shares -- which is a long time as currently the hash rate is low. Changing the shown hash rate to a fixed interval has been on the TODO list for a long time. But for now, just let the miners run a few hours and you will see that the shown hash rate is correct.

Hope we will find the first block soon Smiley

Congrats! We just mined the first block  Smiley Smiley Smiley

Yes, could be due to the averaging over time. The averaging time is constantly increasing.

Yes, I am trying to decipher that too.  I started mining using just one computer and it shows 400h/s on computer but only 35 h/s on optiminer. Unless his table shows 10 times less than what h/s really is, I am missing something here.


if Paddy321 is running 650h/s for 1 hour, optiminer should show close to it. Average s hould be around that speed after 3 minutes, not just after 1 hour.


Reduce the shares that are kept for PPLNS. I used the same settings for the ROI pool as for my HODl pool which gets 10-20k H/s. That was probably not ideal for the start  Grin Now the averaging interval is about 1 hour.

http://hodl.optiminer.pl is now up again for testing!

Improvements:
  • Minimum payout 1.0 hodl
  • Balances are now usually payout out with the next mined block if they are above minimum.
  • Reduced memory usage of pool.
  • Added new balance calculation on miner page


Thanks for all the testers! This allowed me to fix various bugs and improve the UI.

I have removed the experimental warning on the pool page. This means the pool is open for all again, all major bugs seem to be fixed. I'll still keep an eye on it during the next days :-)

Happy mining!

hodl.optiminer.pl down

The DB size grew to >4GB which it was not prepared for. Shocked

Originally, I set up this mining pool when there was no pool available as due to the forced locking of coins for 1 year. This is no longer true and there are alternative pools again. As I do not have the time that would be required to run and monitor the pool at a professional service level, I do not intend to bring the pool back up.

I will work on restoring the DB and paying out the outstanding balances in the next weeks.

Thanks for all the mining and don't forget to hodl your coins!

All outstanding balances have been payed now!

As I noticed that there seems to be only one hodl mining pool alive, I might bring up my pool again. But it first requires some changes to the mining and database.

Thanks for sending payouts for everyone, and thanks for serving us this long!
I would love to see it back when you have time to work on it =)
If you need anything make sure to message us  Wink

Hello, guys! need your help

Code:
[‎2018-01-18 02:29:17.320] [default] [warning] Wait for processing solutions on CPU for 0.0858871s. CPU overloaded? This is slowing down the mining!

mother - ASUS b250 mining expert (x 13 pci)
GPU - nvidia 1060 6 gb dual - 8
CPU - intel core i3
memory - 8 gb

So you are mining MNX I suppose? The CPU seems just not enough for this huge hash rates you get when mining MNX. I'd suggest you use some of the cards to mine a different coin, e.g., ZERO, which uses a different Equihash variant that has a much lower hash rate.

Yes, no ETA on a new windows version.

I might release an linux image for AMD / Nvidia cards with preinstalled miner at some point to make it easier getting started for people that are not very used to Linux.

ERROR: CheckEquihashSolution(): invalid solution
ERROR: CheckBlockHeader(): Equihash solution invalid

Have you considered that the user might just have used the wrong hash algorithm param when connecting to the pool?





If the protocol is different it goes right away as an error on the first submit.

I have tested all the pools listed on the first page. They all report shares mined with a wrong algorithm as correct back to the miner:

It seems the pools internally filter those incorrect shares which is good. But they should be reported back to the miner as invalid.


The pool always get warnings when zcash solution is submited:

 Share rejected: {"job":"ccd0","ip":"::ffff:x.x.x.x","worker":"xxxxx.xxx","difficulty":0.01,"error":"incorrect size of solution"}

And also there is no hashrate.

Unfortunately this is not the case with the problem. Not a single warning is presented in the log files.

Those ppl have good steady hasrate, everything is OK, just when it comes to finding block it got rejected from zcashd.

Just checked, the solution verification has stayed the same in optiminer since version 2.0. You are chasing a red herring here.

The problem also does not seem to be new: https://github.com/zerocurrency/zero/issues/6

My best guess would be that there is NOMP and zerod validate the block difficulty.
