[Stratum][ESMPPS][PPLNS] TheSeven's PPCoin Pool - Official thread

[TheSeven]

I did some works to improve the hashrate graph and fix some quirks today. Sorry for two brief downtimes, I hope it will be rock solid now, except for the daily IP address change :/

I plan to get some proper hosting for this in the long run, but only if the pool really takes off. Right now the hashrate is still a bit too low. The pool still hasn't found a block so far, but it was damn close! Best share so far (found today) was difficulty 281632.9!

Tell me please, can I install the STRATUM on pool that uses a template mmcFE and pushpool?

Hey guys,

Does being located at the backend of the Internet (NZ) make my participation in a pool difficult? Does a pool rate peers based on Latency like online gaming server/platforms do?

Thanks, BDMNZ.

Sorry, I don't really understand what you're asking about. As far as I know pushpool doesn't support stratum.

Kind of. The pool doesn't really "rate" anything, but if you have a higher latency, you'll accept new work later and thus work on stale work longer, producing more stale shares.
For blockchains with a 10 minute block interval (such as ppcoin and bitcoin) the effect of that should be pretty much negligible though. You would lose about 0.1% of rewards per 600 milliseconds of latency.

I have yet to see a new block on the network broadcast in my mining client. (cgminer 2.10.2)  Why?  I assume other pools/miners are finding PPC blocks.

Hm, I'll have to look into that. Do you happen to know how cgminer determines that a new block was broadcast on the network?
My mining rig (running MPBM) has seen ~900-ish new blocks since I last restarted it, so that seems to work fine.

I don't really know.  When mining solo, I can see when new blocks are found on the network.  When mining at Coinotron, it appears that new blocks are announced via longpoll.
cgminer's author, ckolivas (https://bitcointalk.org/index.php?action=profile;u=19971) has always seemed very helpful.  Maybe you could send him a PM for more technical insight into this?

Did that behavior change to reporting vast amounts of blocks during the last hour? I did some change to the pool server to test this...

I am not connected currently.  Let me switch over and check it out...

camel, looks like you found a block just a few minutes ago!
Please note that it will take slightly more than 12 confirmations for the first few blocks to be paid out, because I will be manually verifying the payments, just to make sure that the payment system works right...

The first payouts have been sent!
Sorry if the payments don't match the estimated amounts that were shown on the page, I had to fix some display bugs. The paid amounts are correct though.

Awesome!  Payout received!

I'm going to rework the hashrate tracking of the pool today, to make that react quicker and display more accurate estimates.
So please don't worry if the statistics are broken or showing nonsense values while I'm working on it.
