DLLs have been uploaded. I will create a release but until then, select the Code button and Download Zip. This should give you the entire master branch with the binary and its DLLs. Otherwise the source code with a scrypt-NAH patch is there at https://github.com/catcoin-project/cpuminer-opt-scryptnah.git, I've found it compiles without many issues on Linux and Windows. It needs libcurl-dev, libssl-dev (crypto and ssl), pthreads (or winpthreads) on top of the usual build tools (build-essential, autotools-dev, m4, libtool, automake, autoconf, git, .. that should do it). Let me know how it goes!

Hi, I have also some dll issues. I'm on windows 10. I didn't find any source code so cannot compile and try on linux
The source has been updated at https://github.com/catcoin-project/cpuminer-optDid you get an error message with which DLL was missing? I will upload a few DLLs it uses to the repository to see if that fixes any issues.

cpuminer-opt-scryptnah from github doesn't works, issue erorr for miss some .dll, do you have any new link to download correct version, thanks!
Can you tell me what version of Windows you are using, and can you tell me what DLL was missing? I was certain I compiled a static-linked binary. I should investigate a bit further. It's probably something to do with mingw or it's a system DLL missing. If you can tell me your O/S version and any error message I can narrow it down. Thanks!

I've seen a couple of new miners come along here and there.
Make sure your version has a patched scrypt hash for Strayacoin, as described in the first commit of cpuminer-opt-scryptnah, or use that as a guide to patch your own mining software for Strayacoin. Otherwise your miner won't find any shares if it's using plain old scrypt.

Why does the pool say this? "Strayacoin is a real Aussie crypto project, a community driven coin with its own PoS systems and everything!"
Where is the PoS ?
Scroll down at https://strayacoin.com/wallets/. Email them for more details. I've never used it myself, I'm not part of Strayacoin so I don't have any more details.

Hi everyone, I've added a few new algorithms to Patrick Marie's genesis block generator, written in Go. My fork is here: https://github.com/catcoin-project/generate-genesis. If you download and install go from https://go.dev, you can clone the repo, then run , then . You will end up with a .exe file you can run. Run it without any arguments to see the original demo, or with -h to see a print out of the program options. If you get any problems open an issue on github. I might have left a few edits uncommitted somewhere... in particular builds can be different between Windows and Linux systems because of assumptions about integers which may be unsigned long int on some systems and unsigned long long int on others. I will try and fix any issues like that as I come across them.

I think I can relate the stratum server's difficulty to the network difficulty, roughly.
By experimenting with the setting I found setting it at 1 and too many useless shares came in, and adjusting a bit higher, and there would have been maybe 20 to 50 shares submitted before finding a block. (The network doesn't have a great amount of hashpower, there's only a few miners). So that seemed to be a good setting. It's low enough for all CPU miners to find shares and share the block reward, but not too high so that miners only find shares once in a while. It seems to be mainly for filtering out low shares, and is set by the pool, and might be updated at a later time if needed.
So stratum difficulty is just set by pools and reflects the kinds of hardware and software used and how many miners there are, and is low enough so that all miners with adequate hashpower can share in blocks found.
All the different difficulty numbers were getting confusing, especially because they are all expressed a bit differently. I can see it more clearly now, I just have to jump back and forth between difficulty numbers expressed in hex, as whole numbers and as floating point numbers. I suppose with the numbers below zero it just means with difficulty_1_target / current_target - over time (unusually) the current target is higher than the difficulty_1_target maybe.
Thanks for your reply!

is it not an new coin?? blocks is since 5 years ago?
No, but since the proof of work was updated there haven't been any mining software supporting it or mining pools, so I had to hack on the code myself.

ok, so this can be worked into ccminer?
I forgot this was a CUDA miner, I can't do it myself at the moment, I no longer have a PC with an NVIDIA card. I could patch the code for https://github.com/tpruvot/ccminer which has a GPU implementation and you could try and built it yourself if you have the CUDA toolkit.

how to create wallet?
Go to the releases at https://github.com/StrayaCoin/StrayaCoin-Core and download Strayacoin qt wallet version 2.0.0. If you don't have Windows you will have to compile on Mac or Linux. I can make Linux binaries available if anyone needs one. I found it was difficult to try and compile with the latest build tools on e.g. Ubuntu 23 or Debian 12. I had to spin up a VM with an older version of Ubuntu 18.04 LTS Bionic.

Probably, yes. I will take a look.

wow, didn't know they made their own custom Scrypt algo.
Actually there's no modifications to scrypt itself, my bad. It's just the proof of work logic in Strayacoin - it's modified to look at the inverted bits of the scrypt hash of the block header. So you use scrypt on the block header as usual, but invert the bits, then compare to the target.

I have a modified cpuminer-opt for scrypt-NAH (Strayacoin), which can be found here: https://github.com/catcoin-project/cpuminer-opt-scryptnah. Currently there is only a Windows binary, but if you look at the first commit message there's a snippet of the changes to scrypt.c so you can compile for your system and mine Strayacoin on Linux, Mac, etc. There's also a pool with a modified stratum server at https://pool.larahelpers.com which is the only Strayacoin pool that works with scrypt NAH that I am aware of. If anyone wants to help me test it I would appreciate the help. I want to ensure payment runs work properly etc.

It's not a Strayacoin issue, as far as I can tell. If you are still here, I would say the mining pool didn't update their stratum server to accept scrypt-nah, perhaps? Strayacoin changed their PoW algorithm to get rid of ASICs. I'm sure if you give the official wallet a go and try mining there or at my own pool (you need the modified scrypt-nah binary) you can get some coins.

Hi everyone,
Can someone enlighten me on the meaning of the stratum difficulty set by a mining pool, e.g. 32, and the network difficulty (reported as 0.02... the network has 500kh/s thereabouts, not sure if that's accurate though), and the difficulty my miner is reporting and when shares are accepted? These are below 0.02, usually around 0.005 and less).
I can't find anywhere that explains what these difficulty numbers are and how to think about them in terms of the target hash, if that's what you do with difficulty.
I have read the stratum diff simply filters out work submitted which doesn't meet requirements, but I am not sure why the stratum diff would be set at a certain number, and how this relates to the network difficulty. If the network diff is reasonably low and it's possible to find blocks every few hours solo mining, how would a mining pool know to set a stratum diff that agrees with the network diff? Why would they be different?
Thanks for any help.

I want to sell @12500 USD per piece.
Price is steep. You can get a new one for less than that.

Really wonder if someone was able to run this against compute_75 & what speed bitcrack would hit. I've been running a modified VanitySearch, doing 4.6GK/s on a single 3090. Sadly due to the 86k threads it trying to fill, it goes out of bounds now & then (GPU/GPUCompute.h:54). Just cannot wrap my head around that funny one yet. But besides of me trying to understand that & learning a lot, CUDA should be doing something near that speed on bitcrack too Neat idea. I might give that a go and submit a pull request or fork BitCrack with that function. It should be possible. Edit: my repo is at https://github.com/bitcoinforktech/BitCrack.git which will have some updates in the next few days. Yeah, cuda on bitcrack has this interesting problem on the new drivers. Will try with line info later, was just doing a quick run of your repo. [2021-01-19.17:31:52] [Info] Error: misaligned address ========= Misaligned Shared or Local Address ========= at 0x0000e610 in keyFinderKernelWithDouble(int, int) ========= by thread (160,0,0) in block (0,0,0)
Edit: Most fascinating thing about this issue, is that it runs my full test keyspace in debug exe (400M)[ofc slow af], the release crashes on the error above. I have just installed my 3070 and giving it a go, I've compiled the CUDA version a few times but only for older cards. I hear that I have to roll back my driver to get it working for 3070, 3080 or 3090 cards, but not sure which one. I can't get it to start at all right now on the RTX 3070, using the driver that comes with CUDA development kit 11.2. Aside, I think I know where to fix this, if I can just get it to work on my card so I can give it a whirl :/

It looks like these are scams.
It's probably possible to put any transaction history you like in there and make it look like the address associated with the wallet private key has a balance, but likely the key is fake.
Not sure about all the wallets, but at least some of those floating around have dud keys that don't unlock any Bitcoins. Oh well. It was worth a shot. Trying to recover a wallet with known information that belongs to someone who can't decrypt it themselves for a share of the loot is probably a far better way to use some cracking resources.

Just a little info for people reading this thread. I'm a professional in the cyber security world although I can not say to what degree. These are crackable if you know what your doing, an I don't mean guessing a number and hoping with hashcat. Here is the issue, anyone with wallet.dat that they obtained probably can crack it there self. Let's say that the person has but does not know how to crack. Why sale when they could cut a deal with someone that could. With alot hat said will there be accounts with free coins and tokens on some of the ones "for sale" sure. Some people have realized they can sale a wallet.dat to multiple people because 99% are not gonna be able to crack it. That said if you want to try it that's fine it's your choice just go into it expecting to loose the money you spent on it.
Why can't you say 'to what degree'? I'm also a cyber security professional, I've been a mid-level info-sec consultant for 5 years. My feeling is that if the wallets are genuine, you would have to be extraordinarily lucky to 'crack' them. I agree you have to go into this expecting to lose anything spent on them. I know that cracking these is pretty hard - I have some experience with them. You need extraordinary compute power and time, or really good lists and rules to apply to the lists, and even more time, and therefore potentially expense.
