Pool mining:

Miner uses custom binary protocol first time implemented in xpmclient (Primecoin GPU miner). Working pool instance: http://coinsforall.io/#!/coin/ZCASH

To start mining:
 - Put your T-address or Z-addess to config.txt (need ZCash client installed, online wallet or exchange with ZCash support). Pool support both ZCash address types for payments.

server = "coinsforall.io";
port = "6668";

# Your ZCASH payout address (z-addr)
address = "zthTb2ToG5kuAc11Ni6NxoYjoxQdEr2XvST7XEdLvmHG9k7kotEcwYCaAn1SH4zRdPoXn9kNeFm8CQo k9SNtNgn8d9WcdTK";

 - Configure your GPUs (edit corefreq, memfreq, powertune and fanspeed parameters)
 - Run zcashgpuclient in Linux or zcashgpuclient.exe in Windows
 - Put you address to 'Your Address' field on web site for monitoring workers and payments

Pool system: PPLNS (Pay Per Last N Shares); accounting procedure uses all your shares received during last hour.

Known problems with ZCash:

1. Corruption wallet bug: https://github.com/zcash/zcash/issues/1694 Author says, that he send T -> Z transaction, but it not neccessary, wallet can be corrupted at any moment. Pool wallet goes down an 01.00UTC 29Oct, about 2 hours pool not working. And 7-8 hours needed by repair wallet and send mined ZEC back to pool.

2. Slow and sequential transactions. Z->Z taken an ultimate long time (up to 30 min for creation and up to 5 hours to delivery) and CPU/RAM resources. Z -> T quite faster, it takes 3min for creation and same interval for delivery. If I found way for make transactions more quickly, I implement it immediately, but now I see only one method - return back minimal payment to 0.05 - 0.1 ZEC.

All your payments queued, size of this queue now is 1500 and grows after decrease minimal payment size and wallet corruption incident. You need a long time for wait payments.

3. Another zcashd wallet crashes. Need a time for remove blockchain and download it back. Very often zcashd stucks on block 145 (why 145? I don't know).

Pool issues:

1. "Fake payments" Some clients see payment, but really transaction not sent to network. All this transactions will be replayed.

TODO:

1. Payments without Z-address support. No payments to clients from Z-Address. No payments to client's Z-Addresses. All payment problems caused by new 'z' API which can't be used for pool. For anonymous transactions - OK, but not for pool.  (TODAY)

Done! payouts is fixed.. finally. Need select a procedure for move already mined coins from your Z to T address

2. Rollback 'Fake' payments and return funds to balance (TODAY)

Started. All 'Fake' payments will be deleted, coins return to balance

Final pure stable version will be until 1 Nov. You can continue mining here, or switch pool/miner and return later after launch non-Z version. Or leave this pool, if you think that it's scam.

Windows defender keeps deleting the latest version, marking it with "Virus Detected" even before I can open it. Am I the only one having this issue?

Based on what I am reading z payments are still broken due to a wallet bug.. It might be a while..

[Oklawolf]

My fake and missing payments have been scrubbed and re-added to the requested pile... looks like he's making progress there. This must be aggravating to no end for him.

Had another multiple rig crash - seems to be something poolside causing that, though this time two of my six rigs stayed working. Easy fix on my end.

[Shoma]

If problem is only with Z addresss why i dont get any paymets for 24h on my T address?

If wallet is broken it's going to be broken for sends also from wallet. So payments will be effected no matter what coin.

[swordsaint]

Anyone has unconfirmed transactions on supernova after 6 hours of mining? I have already 0.025 and none of the transactions are confirmed. What should i do? Using Nh miner. Thanks
!!

[Dowper]

Good job, my fake payments are now in requested. I am waiting for the new payment. 

[liomojo1]

Is there a way i can use this miner to mine on nicehash with my bitcoin address?
I tryed to make the confg file but it gives me wrong host!

[sambiohazard]

Hey guys anyone having trouble with mining or payouts can try buying hashrate at genesis mining. I got 0.00011433 ZEC payout for 0.85 h/s. Its not bad. At current BTC & ZEC rate, that payout will ROI you in 90 days.

hashrate is available now from 0.6 h/s for $29. you can also use my promo code to get 3% off. Promo code is in my sig. thanks

[B1tUnl0ck3r]

Does the pool still find blocks?

[adamvp]

lol
my payment went form "Paid" to "requested" now :s
