I'm opening the DGM server for wider testing. To mine on the DGM server with stratum use
stratum+tcp://mmpool.bitparking.com:4333. Note the '4333' at the end instead of '3333' which is the PPS server. The details of the DGM server are:
- 1.5% fee
- f=-0.23125
- c=0.2
- o=0.8
Details about DGM (and what 'c' and 'o' mean) are available at the
Double Geometric Method forum post. Unlike PPS, where constant payments are made for each share, your DGM balance works like a capacitor. When you first start earning the amount is lower while the capacitor charges. When fully charged the earnings are more regular. When you stop mining the capacitor discharges and you still get paid for a period afterwards. So don't panic if earnings seem lower at the beginning. Even if you stop mining on DGM you'll continue to accrue DGM amounts where you'll catch up. Stastically you should earn more on DGM due to the lower fee.
Due to the way DGM operates payments are made when a block is found. You will see a "DGM Estimated Round Payout (BTC)" in your user statistics page. This is the estimated amount of BTC you are likely to earn when a block is found. You'll notice this will have a value in future blocks even when you stop mining due to the capacitor approach described before. You can switch between PPS and DGM any time.
Feedback on DGM, the stats shown, and the parameter settings the pool is using, are welcomed.
Note that this is experimental and if there are issues let me know so I can track them down. I reserve the right to shut the DGM server down should I find a major problem so you should set up a backup server. If I shut DGM down I'll redirect to a PPS server.
First user that hits 50,000 DGM shares and emails/bitmessages/PM's me to confirm gets a 5 BTC bonus sent to their registered BTC address for helping test. Second, third, fourth and fifth get 4, 3, 2 and 1 BTC respectively but remember you need to email/bitmessage/PM me so I can confirm to be eligible! If I have to close DGM early due to issues I'll apportion based on nearest hash rates to 50,000 at the time.
Edit: I'll also throw in 1 BTC each to the top 5 highest score submissions on the DGM server as at Saturday, 27 April 2013 00:00:00, GMT. That's two hours from now. This should give the lower hash rate, but early testers, a chance for a reward.
Edit 2: 40 minutes to go until the 1 BTC awards mentioned in the edit. Currently the top five have 2720, 2080, 864, 546 and 258 shares. Thanks for testing!
