Does anyone know if it is safe to plug in a new asicminer blade v2 onto the backplane without shutting the backplane down?

for the one minute it takes to shut it down and plug it in and turn it back on I don't think you will miss much BTC . better safe than sorry?

so in that case blocks should be found faster and faster...

And that is what's happening. Currently blocks are being solved every 7 minutes or so rather than the normal 10. At the next difficulty change, difficulty will be set to try to bring the rate to once per 10 minutes again.

if someones putting in 2ths and someones pitting in 1mhs there not getting an even share of the block so if the 2th miner increases to 6ths he will see his mining profit per block increase and the 1mhs miner will decrease

That's right per block, but not overall (per difficulty round). If the 2TH/s miner increases to 6TH/s, then the pool will find blocks at a higher rate. The 1MH/s miner will get less per block, but will see more blocks; this balances out so earnings are unchanged for the small miner. (The big miner, of course, will see higher earnings since he increased his hash rate).

I sense that's there's a little bit of confusion about how your earnings can be independent of the pool's hashing rate and perhaps I haven't explained it very well. Best thing is to give a few examples.

First a definition: by earnings I mean the rate of income per difficulty round. This could be expressed as the average number of bitcoins earned per day over the difficulty round.

Let's assume the network hash rate is 2000 TH/s (it's higher now, but was at that a couple of weeks ago) and the difficulty round has just begun. Let's also assume that the hash rate of the Slush pool is 200 TH/s (1/10 of the total network hash rate) and you're a miner in Slush with 200 GH/s (1/1000 of Slush's hash rate).

Let's look at three scenarios:

1. The network hash rate is stable (maybe there's a world shortage of solder and nobody's shipping miners...), Slush's daily earnings are 360 bitcoins (2016 * 25 / 14 * 0.1). Your daily earnings are 0.36 bitcoins (360 / 1000). This rate continues for 14 days at which point there's a new difficulty round with the same difficulty (earnings don't change).

2. The network hash rate is stable but 200 TH/s moves from BTCGuild to Slush (for some reason). Slush now has 400 TH/s and earns 720 bitcoins per day (Slush's block rate has doubled). Your earnings are still 0.36 per day - while there are twice as many blocks now for Slush, your share of each of them has halved. Again, this difficulty round lasts for 14 days and the next one has the same difficulty (earnings don't change).

3. EvilASIC(TM) company dumps an extra 2000 TH/s on the network right at the start of the difficulty round and mines into EvilASIC pool. Network hash rate is now 4000 TH/s and there's a block every 5 minutes instead of every 10 minutes with half of the blocks going to EvilASIC. Slush's daily earnings stay the same (360 bitcoins) and so do yours, but this difficulty round will only last for 7 days instead of 14. When the new difficulty round starts, Slush's and your earnings will be halved (180 and 0.18 respectively).

Yes I think that must be what happened. I had noticed the big drop in shares as well.


According to the ratios, the drop had started during the round 20473, and continued to round 20474. The latter round's reward may not have been affected, as the dropout only occured in its beginning. The former one, OTOH, has been ruined completely, as the dropout covered its end.

Yes I have been watching and now see my phone company must be having issues as I have loss internet a couple times since. Loss it for 5+ hours last night (at least it was over that 5 hour block) The miners start back up and its hard to know what happens if you don't catch it. I am mining with 70 USB miners at about 23.6 GHS

Thank you. Looks like it's necessary to make a post like this from time to time.
Once a month or so there appear one or more miners here who don't catch the principle. They post a nonsense of some kind here, and instead of doing some reading, they claim the explanation here.
Fortunately, somebody always appears here who is willing to make a new explainig post, again and again.. ;-)
Interestingly, it's often a junior member willing to give away his time, energy and knowledge, and to explain the mechanism to some older, but too a lazy member. :-))

the only reason the block times are closer to 7 mins instead of 10 is because of the vast amount of hashing power coming online recently.. in the last month or so its doubled the network speed and bitcoin couldnt predict it so has to wait for the next difficulty re-target to compensate. the next retarget will be a pretty steep one to as bitcoin is now going try to compensate for the massive increase in the last retarget

The thread is at page 633 so I didn't read it searching for a solution tho did search "duplicate share" and didn't find a solution.  I'm running a KnC Mercury and seeing a lot of these:

[2013-10-21 03:10:08] Accepted 019ac0d5 Diff 159/113 KnC 0 pool 1
 [2013-10-21 03:10:11] Accepted 01aeaa0e Diff 152/113 KnC 0 pool 1
 [2013-10-21 03:10:14] Accepted 0207bcfd Diff 126/113 KnC 0 pool 1
 [2013-10-21 03:10:14] Rejected 0207bcfd Diff 126/113 KnC 0 pool 1 (Duplicate share)
 [2013-10-21 03:10:15] Rejected 0207bcfd Diff 126/113 KnC 0 pool 1 (Duplicate share)
 [2013-10-21 03:10:26] Accepted 00341792 Diff 1.26K/113 KnC 0 pool 1
 [2013-10-21 03:10:26] Accepted 0052d1a1 Diff 791/113 KnC 0 pool 1

I tried using a mining_proxy but the firmware has a minimum difficulty set that is too high for the proxy I think.  And, trying mining_proxy.py --real-target 100 fails.

Is there a solution to the Duplicate share problem?  Each gives me a reject and that figure is below:
KnC 0:  | 149.1G/137.0Gh/s | A:307173 R:20267 HW:25192 WU:2183.1/m

Thanks.

There are two items in the thread subject that are no more up to date:

First, but less importantly, the hashrate has been higher than 200 TH/s for some time already. But I understand that Slush may be rather conservative in this direction and not change the subject every now and then.

Second, and more importantly IMHO, the pool is no more "UserDiff". The target difficulty for a miner's shares is now set "automatically" by the pool software.

"Vardiff" was activated about 6 weeks ago.

Sure, but the thread subject line still says UserDiff today.

Its a long time in mining, but only twinkle in the eye of a thread.

Anybody here got a KNC miner, and willing to talk? I just wondered if you are happy with it, how it's built and how it performs. And, of course, does it get the hash that's promised. I got some BFL stuff and more on the way, but I'm really interested in KNC now...
