I haven't witnessed that before, block 21687 showed up processing with 75 confirmations required and some 3 hours in.

Just read back over the last page or so.  

[gourmet]

Slush has to add a small fee to every payment.  If the threshold was lower, this would become a substantial part of the pool's running expenses.  As Slush takes only a small cut for running the pool (2%) there has to be a limit, or some people would claim every tiny amount they earn, and the thing would be unsustainable.

When Slush would include the payout transactions into his own block, he'd be able to pay it without transaction fees, wouldn't he? Can this be a solution?

(Of course this does not solve the problem of Satoshi dust accumulating in the miner's wallet.)

[wdalessi]

Well the payout for the block is not showing yet. It should show in the unconfirmed column, and nothing there yet. Maybe soon we hope.

 

[manic miner]

I have no Unconfirmed rewards showing up for 21687.
What just happened to that one? I looked at it a while ago and it was a 15hr marathon, then its done and we are into a 3hr+.

I thought it was just me.

  Well that's far better than a leak. Down a bit on the reward, might be a coincidence.

[as2davis]

Why is the minimum payout so high.  My computer mines so slowly that it will take me months to reach the threshold.

Are you mining using only a CPU or GPU?  If so, you are probably not covering your running costs anyway unless you get free electricity.

I have a nvidia gtx 660 ti gpu.  I have switched to scrypt mining because I only get 100 M/hash on my card with bitcoins, and I don't have the funds to upgrade to an ASIAC miner.

Still I have 0.00098937 Btc in my account that I want to transfer, but I would never be able to reach the minimum payout.

[KNK]

 

Normal block periode is 10 minutes, so 2 hours is only 12 times the difficulty.

Damn, I need to stop doing math when sleepy ... and where those 6min came from
Sorry

Can't sleep so back to the PC, but don't trust my math until tomorrow.

It seems round 21687 is the missing block we found a while ago, so probably some of the admis is working on that.
The account page shows about 1/4 of my hashrate while the estimated reward is jumping ~10% around the expected one with each refresh, so it is probably catching up with the score or it is messed from the total round time change ... anyway it will be fixed sooner or later

Is it really worth worrying about?  That's currently about 24p (UK) or whatever the equivalent is in cowrie shells.  Still, one day BTC value may go through the roof.  Perhaps a nice email to Slush asking if he would pay you the balance, pretty please.

even with the stats page correcting we're five + hours in and its only showing a CDF of 36.61. .   So its definitely still off. .   Usually we're at 35% of CDF less than 2 hours in. .   It's 50% at 3 or so hours. .  so the numbers here are still off. .   I imagine it'll correct itself as it looked like we were on another round while one was finished. 

[wdalessi]

Basically,

It looks like it was stuck. The time was from the last block. It does not mean the pool was getting any credit mining from that time. The pool got some partial credit, probably from the point they were able to start fixing things. Basically it's like the pool started mining the block somewhere in the middle of that time period. The block really may not have been mining all that time. This could end up as another long block depending on how lucky the pool gets. I would use shares submitted and not time.

I've posted this somewhere already, but maybe not in this thread.

If you want to estimate the amount of time taken for a pool to hit a particular CDF lower tail probability for a given block, you can do better than guesstimating. You can calculate it pretty simply:

Code:

estimated time in hours until lower tail CDF = P : -log(1 - P)*D*2^32/H/3600

D = network mining difficulty (currently 2621404453)
H = pool hashrate in hashes per second (eg 850 Thps = 850e12)

examples
estimated time until lower tail CDF = 0.1 : -log(1 - 0.1)*2621404453*2^32/850e12/3600 = 0.3876594 hours
estimated time until lower tail CDF = 0.5 : -log(1 - 0.5)*2621404453*2^32/850e12/3600 = 2.550339 hours
estimated time until lower tail CDF = 0.9999 : -log(1 - 0.9999)*2621404453*2^32/850e12/3600 = 33.88817 hours

HTH


edit: It occurred to me that you might want to estimate the CDF a given number of hours into the round:

Code:

P = 1 - exp(- t*H*3600/2^32/D)


P = lower tail CDF
D = network mining difficulty (currently 2621404453)
H = pool hashrate in hashes per second (eg 850 Thps = 850e12)
t = time in hours

[anthem]

sorry - sitting on a plane with gogo internet. . .  but yes, I agree with you. ..  that being said - we can both agree that the current stats page of 5+ hours and 35% CDF is not correctl

[necro_nemesis]

Whatever it did or is doing the unconfirmed reward which is relatively low showing in stats isn't showing carried over to the account.

Get ready 3 more blocks till difficulty adjustment. New estimated difficulty 3,129,249,303 (+19.37%)

Well here we have it folks:

Bitcoin Difficulty:   3,129,573,175
Estimated Next Difficulty:   3,704,625,859 (+18.37%)


Fresh off the presses.

So the real question is how does this effect the mind set of miners?

Since it is now very difficult to make anything even with ASIC's . When will the commercial operations of large scale begin to feel and embrace the pain.
At what level does the cost of Hardware, Electricity, Labor and their time make this an unprofitable situation. Of course the new Terra miner is profitable, if you have one.
Basically they don't have one. They have a bunch of older Butterfly labs, AntMiners, and AsicMiner Blades. Throw in some older Terra miner, and what else.

So what do they do now?

That prompted me to put my rig for sale a few days ago. With the new difficulty it's no longer feasible to mine if you have less than 200GHS. Sad...
I actually feel disenfranchised and reluctant to use BTC ever again. I'll lose close to $1K on this whole ordeal (that's if I'll be able to sell my rig at what I'm asking for it). The whole idea of a currency not controlled by anyone is now in the hands of a few large pools/farms.

[anthem]

yes, and this works into the pool "luck"  . . .  because you would rather have bad luck when you're equipment is not as efficient with the difficulty than bad luck when you're able to effectively mine.  Not sure how the next jump in difficulty will be, but with this last week and the extra long blocks we've had, its definitely affected all of us in the pool. 

[guslapins]

BTW, if anyone is interested in 7*AntMiner U1 + USB 2.0 7 port hub and 2* BFL Jalapeno 7 GHS variety -- please PM me. I'm on a business trip, but will be able to ship on Friday. AntMiners are on sale on eBay, so quantity may vary. Willing to let it go for 1 BTC (US$600). If BTC goes down, it will be still around US$600.
