Just over 1BTC confirmed+unconfirmed combined total reward on mining.bitcoin.cz.
This is an extremely slow process. And I think im too late to the game to be investing hardware in it....

HD5850 overclocked running at 330 Mhash/sec, pheonix miner.


Keen to try other pools, if theres any better than this one.
Also want to try a different miner too.

I'm in the same pool as you mate. One of the best I've used. I get around 3.3 BTC a day with 2 HD5850's running at 350MHash/s each (~700 total)..

The difficulty goes up again in about 7-8 hours, by about 50-70% increase!
That will halve what I get a day, but since I started I've got around 17BTC now. And with thecurrent increase in exchange rate (8.5 usd to 1btc), I've made over 130$ :).

I am currently looking into setting up my own mining pool on my vps too. Quite difficult, and might take me a week or two, but if I can get it popular enough to be solving a block per day, It will pay for itself + the bitcoin network gets 'safer' (more pools is better).





Edit: I suggest you try pheonix miner with the phatk kernel. Much better than any others I've tried!

I assume you have that going 24/7?
Oh dear, a difficulty increase, that's not going to help me very much.

I see this long polling thing being discussed, and this pool doesn't support it?

Dude you're lucky, I only get like 2.6-2.7BTC avg per day with slush with my 2 HD5850 at same oc clocks and Mhash as you. Stayed 3 days and left.

Hope you're pool has no fees. Cool

I think next difficulty will be around 420000~460000. Cry But I'll still be rocking 6~7BTC a day (assuming 460000 difficulty) minus NZD$10.8 for electricity a day woot woot!!!

Long Polling is only beneficial if you have 2 or more workers to avoid stales.

Long Polling is only beneficial if you have 2 or more workers to avoid stales.

Long polling is beneficial even with one miner. It significantly cuts down on bandwidth usage and reduces load on pool servers. It also makes the miner more efficient. Without long polling a miner asks the server for a piece of work approximately every 5 seconds. It then attempts to find a nonce for this block that gives the correct answer. It has to keep the time short because if a block is found during this time then any work nonce found between this time and the next work request is stale.

With long polling the miner can reduce the ask rate down to once a minute. If a block is found during this time then the miner finds out via the 'long poll' and can immediately stop working on the old data and get new information. More time spent mining, less time spent getting work, less bandwidth for you and the pool.

I run a namecoin pool and a PPS bitcoin pool and miners that have long polling reduce a lot of load on the pool.

Sweet thanks for the info Cool. Didn't know it benefits even if you use 1 miner.


May I know your pool (and is the server in NZ)?

May I know your pool (and is the server in NZ)?

The namecoin pool is http://bitparking.com/pool. I wrote the pool software in a language called Mozart/Oz to learn about pools and to test how well Mozart's implementation handles load. Namecoin has a low enough difficulty to make testing easier since blocks come fairly quickly.

I tweaked the implementation to do pay per share and use it on the bitcoin chain http://pps.bitparking.com/pool as an experiment. It's running ok for a small number of miners so far.

Both pools run on a linode VPS. I don't advertise or push them as they're unlikely to handle the load or DDOSing that the big popular pools get at this stage.

Nice!
This is exactly what I was looking to do. I also have a linode and wanted to play with the pool's.
Are you running the open source pushpool at the backend?

Ill have to speak to you later this weekend! :)

No, I'm not using pushpool, I wrote my own pool software. A linode is fine for running a medium sized pool I think. The memory requirements for a pool are pretty low, mostly bandwidth issues I think. I'm running on the smallest available, a linode 512. A pool is basically a web proxy that receives JSON-RPC requests and forwards them on to bitcoind slightly modified. All the works in the scoring system and web front ends, which as you can probably tell are pretty basic in my implementation! Feel free to message me if you have any pool related questions.

Sweet, thanks for the offer. Writing the backend sorta stuff is what I'm not too clear on, hence why I thought of pushpool first. I just wanna play with a front end really; got some cool ideas for user stats/notifications that no pool has atm.. Had to write my own c# app to email notify me/twitter notify me when a round finish's with round stats and that. Would also like a mobile optimized front end with summat like iwebkit (iphone fanboi!) or jtouch because I'm forever going to the stats page making sure that my miners are still submitting shares!

What language did you write your pool software in?

I think I need to read more!

Am currently mining for btcmine.com which has notifications such as when pool solved a blocked, 24hour stats of the pool and your earnings of the day and miner down notifications.

Oh Cool, I'll have to check it out when I get home (10ish)..
Is btcmine a pay-per-share? Because I seem to get significantly less BTC per day than other payout methods!

However, Im still interested in making my own pool.

It's a score base (similar to slush) and a no fee pool.

If you're making around 1.4~1.5BTC or more @ 700MHash/s, you're doing fine at this current difficulty.

Yeah, I still need to get my hands on a power meter to find out exactly how much power I am consuming. Do you have a Measurement of the two 5850's?

Am getting a average reading of 0.513kW with my CF 5850 @Core 900MHZ, Mem 300MHZ , but that's including my overall system. Don't know how to get measurement from the graphics cards separately.

Also you might consume more or less, depending on your hardware compared to mine.
