If you mine BTC, you might consider Eligius. Their CPPSRB system records your credits like PPS would, and pays when blocks are found. Long rounds mean the oldest shares go unpaid, but are still in the queue for future payment in a short round. Then if you only mine a certain # of hours per day you aren't penalized in that way.

(Or use a true PPS pool but there are fewer and fewer because the risk of bankruptcy to pool funds is high.)

Ah ok. I'll wait to worry until a few dozen more rounds have happened to give me more data to look at.

Hey Meni, with f=0.0 and c=.03 I'm assuming in long rounds the pool makes little/nothing and in short rounds it makes more than 3% to offset that. However, it seems so far (now that the first few blocks are out of the way and the miners have plenty of score) that in a really long round I'm making a hair over 0% (which is ok) but in a really short round I made a hair under 3%. The short round making 3% of the pool is what had me confused. I was figuring in short rounds (CDF was 2.2%) the pool would make well over the value of c.

Any thoughts? It's possible I have something wrong, although my java and php implementations resulted in the same values and it seems to be functioning correctly for actual miner payments.

Hi there. I'm tempted to try setting up a pool for FRC this weekend to celebrate the hard fork and new difficulty algorithm. I'm still busy getting my TRC pool up and running though.

As far as I can tell, the only thing different I'd need to worry about on the pool side of things is to take the value and address from budget in getblocktemplate and add that as a payment output to the coinbase in the generation area? It doesn't appear the coinbasevalue includes those coins, so I don't even need to worry about that. Just add the addr->value and otherwise treat it like a normal bitcoind server?

Thanks!

My vote for BTC mining would be Bitparking, HHTT, or Eligius.

I'm so confused about your dislike of DGM on short rounds, because it pays out full to the miners. It's similar to PPLNS like that. If lots of short rounds happen in a row, you make lots of coins.

<confused>

Do programs like Electrum or Armory work with alt coins? I'd like to move to something lighter weight than running full block coins on my PC for every coin I have an interest in. (LTC, PPC, TRC, FRC at the moment.)

Thanks.

I can only speculate that YAC was removed from an exchange, and those sites only show info if there is exchange data available.

You could dug up crytocurrency's official thread and ask there if you like.

Price is simply supply/demand on the exchange. Remember supply is "people offering to sell" not # of coins generated. So they aren't directly tied together. Difficulty adjusts to keep generation of new coins steady over time. So the supply of total coins out there is steady regardless of price.

I think it happens the other direction. Price goes up, so more people want to mine, and that drives up difficulty. So it isn't rising difficulty pushing the price up, it's rising price pushing up the difficulty.

If price goes down to $10, a lot of people will stop mining (not cost effective vs power bill/etc) and that will bring difficulty down. If price of BTC went to $500, almost everyone farming alt coins would stop and everyone would pile on BTC...

doublec, at some point I'm going to support passing a worker identifier in the password field. You might consider something like that. Or if you don't allow periods in user names right now, let people connect with "username.1" and log them in with actual 'username' and strip off the .1 as a worker identifier when storing stats?

You can also mine separate coins if you rotate pools. I know someone who mines ppc and trc that way, rotating every 15 minutes.

What?

I was running Ubuntu on a micro server.

I think it was like 10-15? I don't mine on it any more since I'm using it to test my pool out, but was fun learning how EC worked and such.

Did you miss the earlier posts where people pointed out the map from blockchain is of bitcoind nodes, not hash rate? If you click "most stable", you'll see the Kansas City one and the one in Europe are the two most stable in the world that blockchain knows of. So of course they have a large number of connections and relayed nodes...

If Amazon ever offers ATI GPU farms, that might happen. Don't see how the Tesla farms can be cost effective though.

A new difficulty adjustment algorithm is going live soon to better self-adjust for things like lots of ASICs mining when profitability is high, then jumping ship when profitability is low. Terracoin had a similar problem recently.

Bicknellski, just look for the bright yellow box on the left under his name and click it.

Remember blockchain doesn't actually report the IP that found the block (that info isn't in the chain), rather they report the IP that first sent the block to blockchain's bitcoin server. It won't always be the pool itself since blockchain doesn't keep connections open to every node in the network at once.

Depending on the setting for o in DGM, your shares also carry value across rounds like in PPLNS. It's just in PPLNS you have 100% credit until hitting the cap for N, then the value goes to 0. In DGM (depending on the settings) the value of the shares decay geometrically. Since the value of the share is set at the time the share is logged, whether you leave the pool or stay around has no effect on that share's value. Your earnings will vary based on short/long blocks with equal probability.
