Multipool - the pool mining pool (with source code)

[Miner-TE]

Hey Multipool

Just thought you might like to know that http://multipool.hpc.tw (including the user stats sub-d) is blocked by "Websense" at my work. None of the other bitcoin sites are. How the hell did you manage to piss them off?  

Yes, I just checked and suggested a category change.  If accepted, the you should be able to access it within 24hrs (after your work gets the DB update). 

For the record, It was classified as...

This is very interesting. I'll probably join.

You should target Continuum pool if all other pools are dry. It always has 100% efficiency like solo, without all the variance. It will also help reduce the variance of those who mine on it normally, further promoting fair scoring methods.

I'm trying this pool out

instead of trying to block it, why don't pool operators get rid of the exploit in the first place?

You'll have to ask them, but in my experience: Because acknowledging the exploit means admitting they were wrong to start a proportional pool, which is too difficult emotionally.

[Meni Rosenfeld]

By the way, why is Eligius on the list? Didn't they switch to maximum PPS to be safe from pool hopping?

According to http://eligius.st/wiki/index.php/Maximum_PPS this is only a planned feature.

And "maximum PPS" is stupid, it will leave miners without payment for days or weeks during periods of bad luck - the variance is much higher than in other methods. Why can't people use a working method like those mentioned in the original post of this thread?

I'll send over 3Gh/s your way. After a few hours tonight, I'll prolly send it intermittently during the day and then compare it to recent DeepBit & BTCGuild PPSS(pay-per-share-submitted) earnings I've recorded. This sounds really promising though. So far with only 600 shares submitted I have 1 share rejected, which is very good by any means.

[iopq]

my bitcoin address changed, should I just keep using the old one?

I didn't really use any other pools of this kind that don't have "accounts" or whatever

The client will automatically generate new addresses for you. You can keep using your older address.

If you just did it tonight, you cant judge it now. What Utility shows is not what you get and most data from tonight is still pending yet.

i started on saturday and with an unexpected break of 8 hours on the night to sunday and some time on another pool yesterday while this one was down are on it.

Its not bad, but not really a big win yet, so give it some time and judge when you have real earings.

Worked! Thanks for that Miner-TE. Now I can spend my work hours fitting curves to data. Oh, wait .....

The pool seems down again, for more then 20 minutes right now.

Don't worry - it'll give your "shares" a chance to catch up with your "pending" 

Have you got multiple miners set for each GPU for fail over? If you do then they'll mine Multi when it comes back online.

Last night i had but not yet. I am mining on 2 gameingpcs with got one card each, so its a bit different for me, i am not talking about GPUs and not on 24/7. For one of those i need a simple solution where everything can reseted (shut down miners, overclockings, fan speeds) with one click. Today i will install some remotecontroll to be prepared next time.

Does the pool also implement the Lie-in-Wait attack, discussed for example here?

I'm not sure how useful this attack would be in a big pool and a small pool might even be DOSed by dozens of GH/s dropping in for let's say 1 minute or 30 seconds and then submitting a winning share.

You might get more by blackmailing PPS pools threatening to withhold winning shares - you just need more mining power than they charge as fee!

[gentakin]

Lie-in-Wait is probably(?) most (only?) effective on score-based pools like slush's. At least that's the only scenario I've thought about before (not knowing this was already discussed). But this has probably been discussed already.

Judging from what is listed on the example stats page (http://multipool.hpc.tw/user/15iiHfHA3kaEjeBSNKphQoQWuiUHR7Decs), BTC Mine and Slush have pretty poor efficiency. Their score-based reward system seems to work as expected. Or maybe the multi pool implementation is not perfect yet. Now, if this pool introduced Lie-in-Wait, things might change a little.

It's an interesting project!

[Sukrim]

Lie-in-wait is anyways only useful for pool hopping pools like this one here, as otherwise the chace of finding a valid hash is so small, that the extra computations required to see IF a solution would be a winning solution might not really justify the results.

Here still a lot of extra computations would be needed, but at least there's a chance that really someone finds a solution within 1 week or so, depending on the hopping pool size.

[wachtwoord]

Just a heads up: the pool is down for a little over half an hour.

[Coaster]

due to the downtime I've only been able to send around 820Mh/s toward multipool.
For what it's worth, I predict it'll be more profitable than sticking to a single mining pool. My utility is 167 + my efficiency is just over 1

you run bad, mine is 1.77
