GRAND COIN - 1 GRAND PER BLOCK and SUPER BLOCKS released TODAY 13/07/13

[fishyfishy]

Guys, how many GDC's are you mining per day?
I used GDC.DEDICATEDPOOL.COM and I mined 2500 GDC in 8 hours at a speed of 3.3MB/s
Looking at stats I was supposed to mine at least 10-12.000 GDC/24 hours...

Don't know about his pool but can answer in general. This coins difficulty varies alot, and I mean alot. Which makes the "snapshot" wrong because the difficulty can suddenly go through the roof. I'm still hoping the coders will fix this issue and make the coin more average. So for now you can mostly ignore the dashboards/coinwarz/whatever and just check what you receive / day and go from there with your own calculations.

Sad to say, this is the reality with fast diff switching coins. If you check the block graphs page you get a feeling for how it is.

I'll include a block graph to show you guys: http://gdc.nordicminers.eu/index.php?page=statistics&action=blocks and that for only the last 25 blocks.

Thanks for answer!
Indeed i noticed you shouldn't rely on profit calculators... that's the ideal value... but hard to achieve it

I hear you.  I run GDC.DEDICATEDPOOL.COM

I've been able to get the blocks flowing quicker, but honestly, this coin is an odd one.  I'm been playing with stratum settings in hope we can see more constant results.  So far so good, go look at the blocks now.

I've definitely done something because for a bit there it was at 500%+ per block.  Just look at the graph, we're down to around 100-150% now, where we should be and that's acceptable.

Keep the commenting coming in, I'm trying the best I can to tweak this coin   Shit I'm mining it too lol

Thanks!

I can confirm it's working better now! Nice!

The current price at Cryptsy is about 0.00000565 BTC. Buy them while they're still cheap . In my opinion we will hit the 800 again in 1 or 2 days.

That's likely because now everything seems to be working fine.

[Don007]

Indeed, i'm sure it will happen soon. We're about 0,0000058 already. Don't miss your change!

Yes, I have successfully fixed the issue with grandcoin.  We are now operating at better than expected efficiency!!!!  Everyone mine those coins!!

GDC.DEDICATEDPOOL.COM

I've stopped the share values from 250% average to 90% . That means we're finding blocks almost 2.5x quicker now.  Thanks everyone for continued support and comments.  We'll make this the best pool for grandcoin.. keep mining

Hey, come back from the beer looks like now it's f**ed

[Don007]

Seems like many people are dumping their Grandcoins on Cryptsy. Why? Because they had it paused for a day? Quite stupid to dump your coins right now in my opinion, but be my guest. I will buy many of those current undervalued coins

BTC is also diving, so probably those things combined. Now is good time hoard undervalued coins! GDC will rise again.

I'm mining on http://gdc.nordicminers.eu/ but it seems I'm getting a quarter of what I should get with 4.6MH/s

With a difficulty that varies from ~3.5k to 6.5k, I should get in 24H something like 10k to 20k GDC, but I'm only getting ~5000

Their pool page is totally misleading, showing that I should get ~20k GDC with a ~5k difficulty, when in a few hours of relative stable difficulty (4.5k to 5.5k), I got ~200GDC per hour, instead of 600 to 800.

This is not the only pool which is completely of (and it's not specific to GrandCoin), showing great profitability when in fact it's much worse than mining standard LTC.

Did you use p2pool.org?

Grandcoin is just fucked in general.  No pools are able to get the proper amounts.

http://gdc.dedicatedpool.com/index.php?page=statistics&action=blocks

We have 80% of the total network hash and we're still only getting 30-50% of the blocks.  No ideas dudes.. I've got stratum and mpos guys involved and they are at a loss too.  Got the latest stratum build from 4 hours ago too.

This is the issue:  https://github.com/moopless/stratum-mining-litecoin/issues/48

I have personally spent hours trying to fix stratum to deal with this issue, but have not been successful yet.

The problem occurs when stratum tries to submit a solved block to the Grandcoin client which, when it fails, results in a 500 error from the client. The block does not get submitted and so does not get credited to the pool.

The problem is intermittent, but happens more often than not with GDC, and is quite hard to recreate to test solutions on.

I turned the GDC pool off on https://www.miningpool.co for this very reason - as people don't understand the issue and simply decide the pool is scamming them.

[vaelrock]

So a temporary solution would be to avoid stratum based pool in favor of p2pools ?
Where do those coins go after a 500 error then ? who "win"/keep" them ?

Also, the fact that all the pools show in the CONTRIBUTOR HASHRATES a totally misleading and false profit (in BTC/day and/or in USD/day) is borderline a blatant lie, even if it's not the pool's owner fault.
Adding a sentence like "real profit are likely 25% to 35% of your simulated profit" would be more honest.

This happens with other POS coins also, but for some reason in my experience GDC seems to get affected worse than other coins by this issue.

Isn't grandcoin a POW coin?

To the moon! Grandcoin will rise to 0.0003 BTC! I won't sell until that!

Sorry you are right it is POW - 5 am in the morning, I am getting tired..  

I do see a very similar problem on some POS coins - may not be related though

I just tried looping the submitblock call in stratum - didn't help.. 

[ethought]

Where do those coins go after a 500 error then ? who "win"/keep" them ?

No where, until the next pool / miner finds solves the block and the submit gets accepted.

If you look at the block history for example on miningpool.co you can often see the block height only moves a small amount for the time, when it should be quite a few times that. eg.

246727    1000    MoranR    265    23:10:08 - 15/12    3,433,037    0    0%    
246711    1000    pust6602    281    22:55:52 - 15/12    283,800    0    0%    

16 blocks in 14 minutes. When just for miningpool.co it should have been around 28 blocks in 14 minutes. Plus other pools so probably around 55 blocks should have been found in that time.

0.00000413 BTC now.. incredible low. Looks like some people lost their hope in this coin or something. Come on people, buy some. Don't be sad when it's over 0.000008 or something in a day or so .

Looks like some people lost their hope in this coin

I trust this coin and don't sell my 530k.
