it does seem like there's at least one private GPU implementation for PTS, which is great for the person who has it, but contributes to their ability to mount a 51% attack on the network.
I have working GPU miner for Protoshares almost from beginning, but it is uselessly slow. I can open source OpenCL implementation of SHA512, if it will help you.

Hi,
There is definitly a GPU Miner for Protoshare so pls either share it or fix the problem because there are cheaters who eat all the coins
thx

Any news on this one?

Any chance to get back to "fair" mining?


I spent some time over New Years looking at this.  Here's my take:  There's something cool in having a CPU-profitable coin to mine.  If everyone goes GPU, it'll change that.  But at the same time, it does seem like there's at least one private GPU implementation for PTS, which is great for the person who has it, but contributes to their ability to mount a 51% attack on the network.  If you actually care about the coin instead of simply mining, that's a bad thing.  If you just mine, you don't care. :-)  Since you can't put the cat back in the bag, the other option is to let everyone GPU mine.

Which brings us to:

I can write a GPU miner for protoshares.  It'll take some very solid effort on top of the sketch I've already made of how to do it.  I don't really have that time, but I'm willing to do it for a bounty.  I would propose a first-cut CUDA version integrated with some existing miner, in a form that someone like Christian (of CudaMiner) could take and add his auto-tuning magic sauce to to really eke out better performance over time.  Whomever writes the polished version can get compensated for their time by asking for tips on startup or by adding an auto-tipping mechanism similar to the one in yam.  The algorithms will be fairly straightforward to convert to OpenCL code for use on AMD cards, and I'll do a full open source / Apache 2 licensed release of the source code along with documentation.

Are people interested enough to fund this at a level that justifies the time investment?

(To back up my claim a bit, recall that I'm the person who wrote the new-improved Kepler based scrypt mining code for NVidia GPUs, and I seem to have a day job as a Ph.D. computer scientist.  When I say I can write the miner, I'm saying it with absolute certainty.)

Thanks for the open and clear words, Dave. I am absolutely with you. In my opinion it's necessary for the longterm protoshare "health" to implement and release a GPU miner accessible for everyone - given that there already IS a private GPU implementation out there.

The initial statement from Invictus Innovations was that Protoshares will only be CPU mineable. And for every crypto coin (or share) it's necessary to be funded by a motivated mining community. Having a private GPU miner for Protoshares out there in the wild does not improve credibility and motivation. As every crypto depends on trust its community has in it (because it's not backed by physical values like every fiat money... hahaha), it should be desirable for everyone caring about Protoshares to have a fair mining environment.

I think that the current situation of uncertainty regarding the mineability using CPU or GPU may even result in a decreasing exchange rate.

A bounty for developing a GPU miner for Protoshares should be made available. I don't know if Invictus Innovations is the right address for this. Anyway, the current situation is risking the Protoshares reputation.

This is my personal opinion - not necessarily based on facts, so please correct me if I'm wrong ;-)

how to mine solo ? have xeon e1230 or only pool mining for now ? What miner to use ptsminer_avx_intel.exe ,ptsminer_intel.exe,ptsminer_sse4.exe ? tnx for answers

Join a pool, too difficult to mine solo.

Is there an import function of some kind to import PTS keys into MMC wallet?

-MarkM-


I could be wrong but I think the private keys are compatible, so aslong as you held PTS before a certain date then you have been issued some MMC... so just import your PTS pvt key into the MMC wallet (yes thats scary) and then you should have them if your blockchain is up-to-date.

Idea is that DAC's just like merged-mine coins fork off of the original PTS thus are on a block chain that is essentially the same but just different genesis header+block. So just like the Devcoin share list they have for bitcoin developers, they can do the same thing since they are issued Devcoins to their Bitcoin address every round.
You can always transfer your PTS out into a fresh wallet and then import your private keys. This way, you can be less scared Smiley

Does Crypsty Remove Our  PTS ?

Hi Guys, thinking of mining protoshares together with scrypt rig.
I am thinking of this options:

Intel Core i7-4820K
Intel Core i7-4771
AMD Vishera FX-8350
AMD Vishera FX-9590

what would be the best? What cols/min can I expect from 9590?

Or do you know about any other good processor giving over 300 cols/min and costing under 500 USD?

Thanks a lot!

Memory coin is one of the DACs?

We all have some memorycoin because we owned some PTS ?

-MarkM-

Memorycoin is not a DAC. Memorycoin just honors Protoshares.

To be fair, Bitcoin and MemoryCoin are both DACs, MemoryCoin is just as flawed as BTC when it comes to being a PROFITABLE DAC.

-MarkM-


Yup, I think you get it from the PTS wallet with a command in the debug console, then just import it to a new MMC wallet via debug console. I think it was quoted in the MMC post some where and/or on the MMC site.

Update: Here's the site link for importing the privkey to MMC from PTS: http://protoshares.com/redeem.html .

Yup, 1 MMC per 10 PTS. What's the next DAC? BitUSD or BitShares or something else?

Can someone please tell me, can you still mine PTS?  if so, for how long?  Has the last block been found, and if so, is there anything like a PTS 2.0 coming?

I wanted to try CPU mining but it seems I may be late...


You would need around 1600 to 2000 cpm (collision per minuter) to get approximately one PTS a day. If you have the cpu power, then yes. If not, then just trade for PTS.

Anyone wondering when the DAC's come online or are they already? Is MMC (MemoryCoin v2) the only DAC-ish coin at the moment for PTS?
