[ANN][CNC][P2pool] - ChinaCoin (CHNCoin) P2Pool - 1% Fee - Stable and Fast!

[gritter]

ChinaCoin (CHNCoin) P2Pool Server:

http://cnc.crabdance.com:8107

• located in US Central on a low latency 1Gbit link
• based on latest v13.3 P2Pool
• 4 Cores, 16GB Server
• Pays out transactions fees to miners!
• 1% Fee, PPLNS (P2Pool)
• nicer interface based on P2PoolExtendedFrontEnd
• this pool is using the latest CHNCoin client already, if you are not, get it from here https://bitcointalk.org/index.php?topic=322488.0

No account creation required, simply use your CHNCoin Address as username (password is ignored) and you will receive payouts instantly as soon as the next blocks are found (if you have submitted a valid share before the block was found, note that P2Pool share difficulty is higher than normal pools, so it will take some time for low hashrate miners to submit a valid share, however the payout at that point is also higher to compensate).

Mining User: Your CHNCoin Address
Mining Pass: Anything

cgminer example:

cgminer --scrypt -o cnc.crabdance.com:8107 -u yourCNCaddress -p x -s 1 --expiry 1 --gpu-threads 1 --queue 0

Tip:
Ensure the above cgminer settings are applied to get the lowest reject rates: run cgminer then press S and check that Scantime is 1, Expiry is 1 and Queue is 0, if not press S again and change Scantime to 1, press E to change Expiry to 1 and press Q to change Queue to 0. If all settings are correct it should look like this:

Code:

cudaminer example:

cudaminer -o cnc.crabdance.com:8107 -u yourCNCaddress -p x

cpuminer example:

minerd -o cnc.crabdance.com:8107 -u yourCNCaddress -p x

Dont know how to setup your miner? See this thread for AMD GPUs https://bitcointalk.org/index.php?topic=117221.0
When mining on CNC Pools you can follow the litecoin instructions and just change the pool adress to a CNC pool

P2Pool uses the PPLNS system which means after you start mining it will take some time to see the first payouts, usually about 1-2 hours, you DO get payouts if you stick with it!

How did you manage to connect to Blastbob's pool? I'm trying to run my own p2pool instance, but it won't connect to the p2pool network. I'm using this P2Pool fork: https://github.com/chrda/p2pool-chncoin

Would you mind sharing your source code? Thank you very much in advance!

[gritter]

I've taken the network parameters from the codebase you quoted, it should work fine. It connects to blastbobs network by default (bootstrap address p2pool.chnco.in pool01.chnco.in, I think thats him), some other P2Pool for CNC have chosen their own network (maybe using different codebase).

Check that port 12388 is allowed through the firewall, it should connect to other peers then.

local node has around ~5MH/s now and running solid, thanks to anyone sending their hash here

This was with the firewall disabled as a test. I'm assuming you are using 11.4 with just the networks.py files from the link I quoted earlier? Thank you very much for your help so far

Sending hashes your way.  The pushpool's have become ridiculous and I've never tried a p2pool before.

Thats exactly why I choose to setup my own P2Pool, I was on pushpools as well but even though your local cgminer reports low stales it seems that the stale rate from pushpool's point of view is much higher resulting lower payout. So far on P2Pool Im seeing payout much closer to what it should be (variance is higher due to lower overall hashrate at the moment, but over time its definitely more than on the pushpool servers, for me at least)

Yes im using 11.4 with the networks.py from the link, re the DNSLookupError, it can be resolved by some DNS Servers, but others not, e.g. my local ISP's DNS doesnt resolve it (no idea why!), try putting 8.8.8.8 and 8.8.4.4 (Google Public DNS, it can resolve that adress) in your  /etc/resolv.conf

sending cpu power your way to see how this goes

Yes my stale rate in cgminer was like a couple percent, but my payouts were getting to be 4 times less than they were 48 hours ago.  Something not right with the way pushpool scaled as the network hashrate went up and the difficulty still hasn't adjusted from 8.xx yet.

You need to update BOOTSTRAP_NODES in networks.py.. see:

Getting a lot of shares, but my address isn't showing up in the 'payout' window even though there's been about 8 found blocks so far...

Usually with other p2pools I am straight in there after first block found.

What's the go?

thanks for the tip, changing this node as well now (even though it seemed ok with the old adresses for me)

[gritter]

restarted node with updated blastbob network adresses, sorry for the inconvenience

i saw same issues on blastbob's pools, Im sorry I dont know the answer - im running on the official 11.4 P2Pool codebase - its possibly CNC related, allthough over time the payout looked ok to me!

[RetardedMonkey]

Interesting, because I haven't received a payout from bobs either for a while which is what another rig is on

Bobs pool was throwing me stales overnight and very little payout but it seems to have been fixed now. Got about 1 MH/s running at it right now (pool01-cnc.coinloot.com:8499) with -s 5 --expiry 5 --queue 0 and am still getting about 12% stales/invalid but getting payouts every 20 min or so of around 2 CNC.

[RetardedMonkey]

Okay, just got a payment then... hmm...

[phorensic]

Ahhhhh, this p2pool is feeding my GPU's much better than the flaky pushpool's were.
