You need to install CUDA toolkit for it to compile kernel

hi tacotime
can you describe the steps we should process for win+nvidia because i ve tried many things but no success
I second this  Huh

I will have to try later when I get my nvidia rig set up, I've used reaper + linux but not reaper and windows for LTC mining

Got a Sapphire HD 7970 3GB OC w/ Boost that gets ~500-600khs with CGMiner in GUIMiner-scrypt.
I can't seem to get Repaer to work though, I get

 "Error 52 getting work. See http://curl.haxx.se/libcurl/c/libcurl-errors.html for error code explanations."

Any suggestions?

Server or port entered incorrectly

Thank you so much for writing this, TacoTime. I built my first rig after your Noob instructions thread, named it TacoMiner.

Well, TacoMiner is running now at 561 K/hs, which is nice but it seems like only one of the 3 7950's is working.

How do I turn the other 2 on ?

The first LTC I mine will go to you Smiley

Hi, make 1 cgminer or 1 reaper for each card, then change the card number in the drop down menu for device to use a different card Smiley

Exactly. When we have a user in here (tacotime) saying he wants to "Pump n dump" not long after release, failing to get a simple daemon to work and then saying the coin is a scam in the space of 3 hours it shows how ridiculous some people here are.

There was no premine, if you missed the 24 hour boat to mine easy coins then it's your own fault, it was open from the start. It's still returning more to me than Litecoin mining right now even at 2MNC per minute block. We'll see what the future holds with an exchange, litecoin has shown us you can never know what coin will be worth something one day.

Daemon didn't work (ran, responded to queries, never downloaded blockchain after a half hour).  Couldn't tell you what's wrong with it, but the fact that you guys have a 5000 coin bounty for the windows GUI build speaks volumes as to the technical prowess of the devs involved.

Not to mention they decided not to address the difficulty coaster exploit in any way despite enhancing the difficulty adjustment time.

I pump and dump most of the useless coins, yeah, but this one is especially stupid.  Even if I mined yesterday I would have gotten barely any compared to the first 24 h.  And now you're at block reward 2 after being at 500 two days ago?

I was able to open guiminer , but now it doesn't open and just stays on the taskbar , tried reinstalling it same error , any Ideas Taco ?

It's a bug with wx where for some reason it puts the program 5 monitors away
1866  Alternate cryptocurrencies / Altcoin Discussion / Re: Want to make an alt coin that actually changes something? on: April 03, 2013, 09:02:30 PM
Yes, but do we have any actually new ideas or goals in mind?

I'm most likely in anyways.
Much needed improvements to Bitcoin + unique change.
We would need to agree on what these improvements are. Currently it seems, everyone in this thread is excited but has a different concept in mind.


I will try to publish a paper within the next few days -- I suggest other persons generate technical papers and specifications as well.

It will throw an error if you have certain security settings on, eg incognito mode or no cookie storage

2) Stake kernel is verified before block connection to prevent a type of DoS attack on block-chain storage. This also requires a hardening point consistent among all nodes. (As of v0.3 this hardening point is about 21 days due to the 9-day modifier generation window)

Can you elaborate on this?

Namely:
1) What stake kernel is and how it is verified, and what you mean by "block connection".
2) What a hardening point is, and what the 9-day modifier generation window is/means.
1869  Alternate cryptocurrencies / Altcoin Discussion / Re: PPC Stake on: April 03, 2013, 07:26:30 PM

Just like PoW mining there is some luck involved.  It is based off of how long they haven't been used for and also how much you have.  If you send it to another address it is reset.  But this doesn't exactly discourage spending cause its just 1% ppcoin per year.  And this method is quite secure also because it is hard to get 51%+ stake.  So instead of power protecting the network we have the coins protecting the network.

Oh!  That's interesting.  So you'd need to somehow get 51% of all the PPcoins available to have control over network.  That's a lot harder to accomplish, since, in BTC's case, you can coerce a group of miners into one pool and thus take over the network in this way, but you'll never coerce someone into sending all their coins.  However, if this managed to happen, it would be difficult to reverse the effect, wouldn't it?

Aside from that.  It would seem to me that you'd be better off putting some PPcoins in cold storage, and having a separate wallet in which you spend.  The cold storage coins slowly build up, and if you gotta break into it to get more funds, you have a few more than you had before.  1% really isn't a lot tho Tongue  It's almost pointless, lest you have quite a nice sum.

The other major problem is that for people with small sums, the amounts generated will eventually cost more in fees to spend than the stake outputs themselves, though SK states he also isn't concerned about this.

Also, stake isn't generated w/o being connected to the network, so cold wallets per say for stake generation are impossible.

I know selection of what coins to spend will be handled by multiple wallets, so one would have a wallet for spending and another for saving up coinstake. Anyway, this is something I could certainly work on in the near future if you would find it helpful. Aside from the things you just listed, are there any other specific questions you have? If you have a list, feel free to PM me

Sure thing.  I want to help as I have a fork in mind for PPC in the future, I just don't understand enough about it right now to really trust forking the code.

1872  Alternate cryptocurrencies / Altcoin Discussion / Re: PPC Stake on: April 03, 2013, 07:07:01 PM
That's interesting.  I think I get it; by ending PoW mining, people will no longer have to burn loads of electricity and burnt computers, and instead, all that they got through the mining (and selling) will then be used to "mine" the rest.  So do the coins get automatically added to your wallet based on how many you have at the time?  And if you move them at all, does the counter reset?  Very unusual.  And is it as secure as the PoW method?

Correct.  PoS blocks are automatically mined starting with 30d of coin age unless you tell the daemon or qt client not to.  If you move them, it resets your coin age and you have to wait another 30d.  No one knows if it's as secure as the PoW method yet.
1873  Alternate cryptocurrencies / Altcoin Discussion / Re: PPC Stake on: April 03, 2013, 07:04:23 PM
It explained coinstake and why hashing power is not needed for network security just fine to me. For specifics on implementation, one can look at the code on github

The paper fails to explain a number of key characteristics of the chain, such as selection of the coin stake returns, the linear increase in coin stake return from 30 to 90d, why those timelines were selected, how the chain is designed to prevent PoS spamming, etc.  If you're one of the new devs, you should start talking about this stuff publicly.  As far as I'm concerned, the original PPC paper is far from technical and fails to address many of the potential vulnerabilities and shortcomings of the currency.  It's been my gripe since day one that the original paper borders on musings.
1874  Alternate cryptocurrencies / Altcoin Discussion / Re: PPC Stake on: April 03, 2013, 07:00:04 PM
After sitting on coins for 90d you make 1% per year mining stake blocks.  Stake blocks begin to be acquired after 30d.

That's odd.  What are they encouraging by doing this?  Save more?

No, eventually PoW mining will end and blocks will only be mined by PoS.  PoW is intended to give the initial distribution of coins to the network.  The 1% per annum is a tiny incentive to keep people mining coins so stake blocks are still generated.  It's been something that bothered me about the chain from the get-go, since it's not a particularly big incentive to let your coins sit and do nothing for 30-90d +, but Sunny King thinks it will work.
1875  Alternate cryptocurrencies / Altcoin Discussion / Re: PPC Stake on: April 03, 2013, 06:59:16 PM
Actually, the paper seldom outlines any of the protocol specifications.  Rather, it just discusses the abstract theory behind the coin.
1876  Alternate cryptocurrencies / Altcoin Discussion / Re: Want to make an alt coin that actually changes something? on: April 03, 2013, 05:52:56 PM
There are quite a few things to discuss. We need somewhere to throw ideas around. If there is serious intent behind this I could put up an ad free phpBB forum or something similar for discussions.

Give me some psuedocode and I'll try my hand at implementing it Smiley

Okay, I'll give a shot at writing up the technical paper this weekend.

It will probably kill a cheap power supply in the short term,

but a good PSU is fine because they're usually rated for more.
