[ANN] [LTC] [PPS] [OTP 2FA] [Stratum only] LTCMine PPS mining pool (3.3%)

[Balthazar]

Up again.

Unfortunately, DDoS protection costs enough to decrease project profitability index to <1 values. We need to think about our future strategy.

There is no automatic payout planned currently. You can process manual payout in any time without limits and fees.

Balthazar, a couple of days ago you wrote me this... and I notice now that all the rules are changed.
I think that the changes should be displayed on the account and the site should also ask to accept the new terms.
So a miner can chose if leaving or keep mining with the new rules.
I have found your action quite unilateral...

Hi Balthazar

I have the Payment at 19:49:08, is it because of DDOS?

Usually it is at
19:00:01   
17:00:01
16:00:01
15:00:01

Thank you

It was the manual payment.

You are correct with this. But unfortunately, sometimes there is no another option.

New payouts stack isn't ready yet, I've planned to add announce later. Anyway, index page updated.

Shares are accepted. But I see manual payments at 22:11:46, 22:10:57. Do you recommend to use backup pool?

[Balthazar]

I've started payment script manually at this time, to check reindex operation effect. It doesn't affects your mining results.

Do you recommend to use backup pool?

It's always recommended to setup backup pool(s). Even if everything is fine on your main pool.

My rewards for the previous hour of work is showing as 0.00413076, when I have 3.7mh on your pool. I was hashing the entire time today, even when your site was down all of miners still accepted shares. my average hourly rewards have been around .25 is everything okay on the rewards payout on your pool?

DDoS caused the problem with statistics update at this time. I have shares log and work will be recalculated.

Seem something like this happens to me, too :\

[Balthazar]

Don't worry. Everything that you sent is logged twice.

I noticed today that my miners were getting much higher difficulty shares than normal.  My 3 x 7950 rig usually gets around 200-300 difficulty on this pool and I just checked it now and I am getting shares in the 800 for difficulty.  I know my rig is probably not finishing shares as the difficulty is too high before the block gets solved.  Any reason for this increase in difficulty?

[soundasleep]

A few days ago I added support to keep track of your LTCMine.ru mining wallet balances to CryptFolio (thread). This helps you keep track of mining pool balances over time, and generates reports (such as your overall USD net worth).

I also added in a new feature to keep track of your mining hash rates as well (still being tested).

[Balthazar]

I know my rig is probably not finishing shares as the difficulty is too high before the block gets solved.  

It seems that you are not quite well understood how it works.   There is no "too high" or "too low" difficulty, and share can't be "finished".

diff-1:       hash < 0x0000ffff000000000000000000000000000000000000000000000000000000, one PoW hash per 65535 avg.
diff-256:   hash < 0x000000ffff0000000000000000000000000000000000000000000000000000, one PoW hash per 16776960 avg.

Your OpenCL kernel searches the diff-1 hashes and then miner tries to test it with requested target (diff-256 in our example). If it matches the PoW condition, miner sends this result to pool, otherwise it tries another found hash. I.e. the share target it's just a filter for results of work which you are already done. Input/output data and the work amount per time interval always will be the same. With diff-256, for example, you will send 1/256 of diff-1 hashes which you are found. If you want to take a closer look on this process, try to start cgminer in debug mode

The only side effects of higher difficulty are

• lower speed calculation precision;
• slightly higher variance, but it doesn't matter with PPS.

Any reason for this increase in difficulty?

An attempt to decrease DB load/traffic usage and make average rejects ratio lower. Minimum diff will be decreased to 96-128 when new server will be available.

Thanks for the detailed explanation.  That will set my mind at ease.

[Balthazar]

No problem

[Azure]

Just logged onto this thread after quite a while.  I had noticed today my rewards showing very erratic numbers (some too low and some too high), even though my hashing rate was constant, and my overall daily expected reward total is lower than expected today; but the explanations I've seen here seem to have answered my question(s) I had regarding this.  You're still going to recalculate them then?  Thanks Balthazar.

Could you send me PM with your payments log?

Done, thanks,

[BBN]

Is this correct : --scan-time 30 --expiry 30 --queue 0

Thanks

EDIT: When I put the line as extra flags in Guiminer Scrypt Alpha the workers wont connect to the pool

Try this: -Q 0 -s 30 -E 30

Thanks mate, the stales are just below 2% with the settings..still quite high
