[gritter]

1 worker Accept 163 Reject 48
2 worker   Accept 460 Reject 120

7 hours 2000 Khs only 10 CNC!!

first of all, thanks for sending hash here

rejects are normal, if somewhat high, are you running with the parameters mentioned in first post?

re the payouts, an hour ago I disconnected this pool from blastbobs (and others that mine there) p2pool network and deployed a P2Pool version that uses the same parameters commonly used by the FeatherCoin P2Pools (which have less payout issues than were reported for the CNC P2Pools)

I did this since I was just seeing to low payouts on the other P2Pools, I really believe by changing to FeatherCoin-style parameters the payouts should be more fair now

so far 1 block was found since the new parameters are in place and payouts for the miners connected then were certainly higher, now just waiting for next pool to be found and get more hash into this pool to get higher payout frequencies

basically I dont want to run a pool, but I felt other CNC pools were just paying out really badly, hence I started this one, if anyone has any tips re optimizing P2Pool or re making the payouts more fair Im all ears!

after 3 hours only 1 block was found, so something must be wrong or extremly unlucky, so I decided to hook back onto blastbobs P2Pool network, at least variance is lower there than 1 block every X hours standalone

Dont connect to bob's nodes.

He's not allowing outgoing node traffic.

Seems like sometimes our shares are not shared with bob's shares

I think your shares might missing sometimes then resultning in zero payouts

[gritter]

http://litepool.eu:8400/static/ this is the best p2pool node, been using it for 24 hours with no issues now made 1000 chinacoin!

its connected to blastbobs pool as well, so basically the payouts are the same...except the DOA is higher and efficiency lower than my node here, so no thanks

argh! thanks for the hint, i suspected something was not quite right, the payouts feel spotty sometimes, changing again now, sorry to the miners for the hickups, getting there!

How do you know its connected to blastbobs pool?

because it is, and since you are spamming it and hence probably control it you should know too

crashed while joining the new P2Pool network while I was away

up and running fine again now!

[gritter]

someone PM'd me about the outage before as well, all I can say is sorry, i switched to another p2pool network where payouts hopefully works as intended, this is live now, after the switch was made the node never synced up properly, since I was afk I didnt notice until a couple hours later.

anyways, its working fine now, and paying out already!

[LeftToeCut]

gritter , which network did you switch to ? what are the hosts?

I have seen the Pool Rate dropping over the last few hours, is that the same for everyone or am I loosing some BOOTSTRAP_ADDRS?

Pool rate: 142MH/s (29% DOA+orphan) Share difficulty: 0.105

Im using the code from https://github.com/skralg/p2pool-feathercoin now, this will bootstrap to http://chn.p2pool.skralg.com:8109

SHARE_PERIOD and SPREAD are still badly chosen for CHNCoin. That won't make many miners happy...

SHARE_PERIOD and SPREAD are still badly chosen for CHNCoin. That won't make many miners happy...

YES, #$%@#, I setup my standalone node with SHARE_PERIOD=30 and SPREAD=120 (what some FeatherCoin P2Pools were using), however even with 40MH/s only 1 block was found in 3 hours, that could be extremly unlucky, but rather I think something was wrong, however I used the same code that worked fine connected to bob's network before, so not sure if changing SHARE_PERIOD and SPREAD too aggressively will cause blocks not to be found

Do you know if its possible to set them to 30/120? Here is what I had tested (first tested with 30/120, then after no block found for 2.5 hours got cold feet and tried 5/120 thinking that long share_period might somehow affect finding blocks, probably not the case, but I dont know!):

some minor thing that doesnt look right is

shouldnt it be? (two zeroes less?)

Hum should have been ~35 minutes. But it's quite possible to have bad luck like this.

If you are truly standalone :
- make sure nothing can connect to your node,
- it doesn't have any data to find peers from,
- it doesn't have any bootstrap seeds.

You can play with share_period and spread any way you want (you could mine solo connecting directly to your chncoind too, but p2pool's web interface, especially with the enhancements you can find on github, is far nicer).

But if you missed any of the points above hell will break lose : your node will not understand why its shares aren't accepted by the rest of the network and vice-versa. If it becomes overloaded trying to make heads from tails on a fast coin like CHNCoin you might easily generate orphans.

Hum, didn't check CHNCoin actual subsidy rule, but I suppose you are right. Shouldn't be a problem right now: this would generate invalid block only after the first block reward halving.

Thanks for your insight!

All the above was correct, e.g. node was really standalone with no old peers (firewall blocked and clean codebase and me observing peers: 0), no bootstrap since i had removed that (ip in code up there was just a 2nd testnode running same params i had setup).

So maybe it was really bad bad bad luck, but still having such bad luck was probably not going to be acceptable for miners

I might still try again then with those optimized parameters on a separate node from this one.

Hmm only getting half those figures. It was up over 400MH/s Pool rate 6 hours ago.
I am still running Version: 11.3-16-g104a596-dirty could that be a problems?
