How are altcoins sent?
The same way bitcoins are. Press the withdraw button on the user page.

You cannot add an altcoin address to an existing mining account (@doublec: Or did you change this meanwhile?)
You have to open a new account, and while you do so you need to provide all the coin's addresses you want to merge-mine.
No one can change the addresses afterwards. (Most exchanges and wallet providers give you temporary addresses. Do not use these.)

USD: 0.001 BTC       EUR: 0.001 BTC        Amaz.coin: 0.000 BTC

Click withdraw.

If you don't own the address anymore, you don't get the coins...

setup a new account and move forward.

This hasn't changed, all addresses remain read only. To add an address you need to create a new account.

What's up with the run of bad luck we're having? The last block was a 6.7x difficulty and a few blocks back there was an over 4x difficulty. Since the difficulty change the pool has averaged 1.6x difficulty. Bring on the counterbalancing good luck please!

The pool had another 4x difficulty block, continuing its run of bad luck. Thankfully it was followed by a couple of short blocks putting us back to averaging 1.5x difficulty since the difficulty change. After seeing what's happened to Ozcoin, where a PPS bad luck run caused reserve issues and they had to disable PPS, I've re-enabled my DGM payment method testing code and am running that alongside PPS to test and compare results.

I may offer DGM alongside with PPS at some point, or leave it there to enable a switchover if PPS bad luck results in pool reserves getting dangerously low. I like PPS for its simplicity but I'd rather switch to DGM than go bankrupt if the reserves run low. Normally I'd just buy more reserves but the bitcoin price has risen so high since I started the pool that's not really an option when block swings can be 10,000 USD.

I hope I'm not alone with this - but I very much appreciate the work you're dooing with the pool! Especially since there IS a risk for you (yes - real money - and not "just" the risk of "complaining" users) you HAVE to make a profit from the poll. Not just for reserves - but also for your work and risk!

I would not mind a higher fee. Especially in a PPS pool!

PLEASE make a decent profit! You've earnd it!

Thanks, I appreciate the kind words. At the moment I'm planning to add DGM to the pool and offer both PPS and DGM. The choice of which reward scheme you want would be based on the server you mine on. I will probably have a higher fee for PPS and a lower fee for DGM. I'm running DGM at the moment in testing and it seems to be working fine.

There's a miner on the main stratum server that is sending invalid hashes and getting H-not-zero responses as a result. It looks like they haven't noticed. The hashes look to be scrypt based. If You are user "Lxxxxxe" ('x' are other characters, blanked out to prevent revealing the name) then you might want to check your configuration. It looks like you have an asic and it's being wasted.

There are two miners on the stratum2 server that appear to be asics but are forcing a difficulty of 1. This is causing quite a large bandwidth usage on the server. I've forced that stratum server to send a minimum of difficulty 8 shares as a result. If you're on that server please check your password to see if you're configured for difficulty one shares.

Pool is back up. I've defragmented the wallets and they're currently empty. I'll be sending the funds from the old wallets shortly then withdrwals can resume.

New stats added to the user page and the userstats JSON API:

  • Shares for round. This is the number of equivalent difficulty 1 shares submitted since the last block found
  • PPS for round. This is the number of BTC earned from the PPS system since the last block found. If you haven't done any DGM mining (when it's enabled) this should be the 'shares for round' multipled by the current BTC rate - assuming difficulty hasn't changed mid round.
  • DGM Estimated Round Payout. This is the estimated amount of BTC that would be earned when the next block is found for the shares submitted to the DGM system.

The main page also shows the hash rate going towards the DGM reward system (not currently enabled, still in testing).

Excellent stuff. Nifty to use in say...an Android widget...cough..

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!
