I have obviously made an error. Prices don't match in LTC or BTC. No deals until I recheck the correct prices !

[daemonfox]

Is there something wrong with SKC? Is it mining and difficulty keeping up properly? Is the wallet crashing or forking?

So... what you're saying is... most people are just bitching because A. there is no compiled, dedicated GPU miner... and B. no exchange has picked this up so people can dump and feel better about using their hashrates?

I've been mining SKC for weeks... I rarely even check my miner or wallet... only to make sure it is indeed mining... and I am happy with my results thus far with only a couple of i5s.

If all you have to bitch about is you can't GPU mine and you can't list your stash on an exchange, no wonder the dev is silent... THEY DON'T WANT YOU PUMPING AND DUMPING THIS COIN!!!!!

There is nothing to fix, hence the dev should be able to just sit back and watch their creation unfold... have some GD patience... jeez.

I'll be holding my SKC just like I held my MEC through thick and thin until I cashed half today at it's peak... bought all new pieces for a gaming rig from Amazon through Gyft purely from MEC profits... one day SKC will do the same.

wanted to buy Skeincoin. UPDATED PRICE...
10k SKC for 0.014 BTC      or 1LTC
5k SKC for  0.007 BTC       or 0.5LTC

Daemonfox: we'll see, we'll see. I'm keeping my SKC's by the way. Those prices are ridiculous imo.
This is the first coin i've seriously mined, so it's my favorite. But what 's the use of a coin without a value?

[mladen00]

I'm keeping it too. It's my first 1000+ coin, so i'm attached to SKC.
I wont sell SKC, untill price is so bad.
But...what is a good price for SKC?
When SKC will be on market?

Any news from creator of SKC?

Any news from creator of SKC?

I mined over 1000 XenCoins and they were nearly worthless.
Some people have GPU implementations for SKC and they are able to mine 1000 SKC in 1 hr. So when SKC will be traded on Cryptsy or somewhere else, I think 1000 SKC is nothing...

[barwizi]

I maintain, 0.125 LTC per 2500. I pay fast and accurate. buying 400k.

Sorry but I have to disagree with you:

As it seems there is no hidden miner making 1000SKC/h or what ever with his GPU; this you can find out by just comparing some numbers:
There is only one pool mining a signifant amount of SKC on "coinmine" ( 24200 coins per day that is roughly the 32 SKC per 2min).
Top miners now mine with 10-27 Mh/s. My simple now already nearly 3 years old notebook, with a i7 reaches arround
1,2 Mh/s. So with some high end machine and - lets say- a bit affinitly 10 Mh/s is totally ecspectable.

I also think you cannot compare Skeincoins to XenCoin, because:
XenCoin had been premined (5% = 105mln coin allready in the beginning ); I think this is always bad
if you want to have a currency with high value and trust, when there are a lot of alternatives.
And the generation rate of XenCoins is 37.5 times higher (200 XenCoins per 20 sec vs. 32 SkeinCoinds per 120 sec)

I'm able to mine SKC at 30 MHs (some i7, FX8350 et al) but other coins are more profitable. That's the reason I'm currently not mining SKC and also the reason why you currently see no one mines SKC using his GPU. redorder and some other people also mined on coinmine at 160 MHs - others 330 MHs. redorder already posted his code for mining SKC using poclbm here: https://bitcointalk.org/index.php?topic=322828.msg3584121#msg3584121
Red Kendra also confirmed that it's not that difficult to create a GPU miner. I'm not a OpenCL/GPU developer but I also created an OpenCL implementation for this coin...

I agree with you that it's not that easy to compare SKC and XEN. It was my mistake. But as long as the coin isn't on any exchange yet, it isn't worth anything... that's also the reason I'm selling (better: sold) all my mined SKC coins.

[ludd]

where can i sell my 1200 SKC?

[asor]

where can i sell my 1200 SKC?

barwizi or Majormax

[Majormax]

where can i sell my 1200 SKC?

I will pay 0.0015 BTC for 1200

[Majormax]

Paying 1LTC for 12000 SKC

[surfer43]

I will pay .03 BTC for 30K SKC

Been fiddling with this for days now and still can't get any sense out of it. Guess my coding skills just aren't up to scratch! lol

Please don't hesitate to ask your questions (but not about cgminer inner structure, I have spent couple hours trying to get my head around it and gave up).

[D4T]

Well I'm at a stage where poclbm mines but all shares are rejected so i must be doing something wrong.

I want to be sure I'm sending the correct data to your opencl kernel but unsure which parts of the state, state2 and f arrays poclbm generates i should be sending as what variable. In particular I'm referring as to what i should supply for "data16", "data17" & "data18".

Are you calculating mid state in python anywhere?

I think a couple of code snippets will make it more clear..

in Switch.decode:

Code:

            binary_data = block_header.decode('hex')
            job.headerX = binary_data[:76]
            job.dataX = unpack('<19I', job.headerX)

in OpenCLMiner.mining_thread:

Code:

                    state = skeinhashmid(pack('>16I', *work.dataX[:16]))
                    for i in xrange(8):
                        self.kernel.set_arg(i, state[i * 8:i * 8 + 8])
                    for i in range(16, 19):
                        self.kernel.set_arg(i - 8, pack('>I', work.dataX[i]))

I do not use poclbm's engine to recalculate the merkle tree, just always use full getwork as it has arrived from the server. Probably it does not play well with stratum, but works to some extent.

skeinhashmid is a ctypes wrapper for skein calculation in shared lib, I believe I have posted the C function for that somewhere below the kernel itself.

Thanks reorder

I won't lie, this is still a struggle for me but I don't expect to be drip fed bits of code until it works. I'm doing this to learn and I'm certainly achieving that so thank you
