Re: [8500 GH/s] Slush's Pool (mining.bitcoin.cz); TX FEES + UserDiff; ASIC tested

I'm wondering if combined mining is actually a waste of computational effort -

Bitminter has 11.5TH and got 17 BTC blocks today so far + 79 NMC blocks
Slush got just 9.7TH but got 25 BTC blocks today so far + 1 NMC block

So, if that's the case - I'd rather have BTC than MNC.

we can have both, nmc wont take anything at all away from btc.  It just needs to be set up.

I don't think that's the case, Slush created the stratum protocol and has said merged mining doesn't work (yet or at all I'm not sure).

Stratum is not limited in terms of merged mining.  It's a matter of adding merged mining to the pool software.  Both Slush and BTC Guild have elected to stop supporting NMC with Stratum due to complete lack of development.  NMC is based on bitcoin 0.3 code, has had NO active development in over a year.  It is a failed experiment only being kept alive by people taking advantage of others with pump & dumps.

Thanks for the clarification.

Also it looks like the last payout went out with 0 tx fee. Pretty sure that hasn't been the case in the past.

I keep seeing a lot of people that I think are confused how pooled mining works.
We aren't all doing part of a big problem, and a round is not just one block. Every time the network finds a block the problem changes cause they are all a chain. A share isn't a piece of a puzzle it's a lottery ticket. And we are all pooling our lottery tickets in hope one of us wins with the agreement we all split the proceeds. So this %CDF isn't coverage of a problem space it's just a probability that a winning lottery ticket will be made for the latest link of the chain.
The real trick is that we are all working on low difficulty attempts so we can make lots of them in the hopes that by chance we'll hit one that is above the required difficulty.
Or at least this is what I'm pretty sure is the case usual disclaimer applies I'm not an expert.

I think the point is...

You may be able to make a little more by mining @ a pps pool during the beginning of slush's rounds, then coming on at the back end of a round on slush to get your reward for that block.

BUT, you won't be taking extra profits from everyone else @ slush.  You will still be getting your fair share.  As opposed to mining only right at the beginning of rounds, when you find a very short round, you actually make more than you normally would, and take a percentage of the share from the other miners on slush.

I could be way off base here, but that's how I interpreted it...

So you are saying a miner working for an hour before a block is found is not actually doing anything towards finding the block?
You are contributing little work but getting a big share from the block. The block has the same value no matter how many miners are involved, so those who have been mining continually with slush have to lose out!

Yes, you're viewing a round as one monolithic problem solved by the pool for the network. Except the problem solved is extending a chain, so everytime a block is found on the network the problem changes. It's all a race with randomness thrown in.

Surely if the rounds been going on one pool for 45 minutes, Then no matter how long the round continues, thats 45 minutes where you are being paid on a PPS. You then earn a few shares from the pool with considerable value. If the round ends within a couple minutes, its not much but you're miners haven't lost much.
If its a few hours, then for the 45 minutes you have been making coins while everyone else here has shares which value is now void.

Now whether 45 minutes is the sweet spot I don't know, and without looking into the maths properly / how much you get per share at a PPS i can't be certain you would earn more, but It seems probable.

Will work it out later. Hopefully you are right and the numbers will prove me wrong!
I mine on a fairly low power system. 40Mhash. If my last share is 30s from the end of the round I seem to get twice as much as if its 2 minutes!
Ok, I am surprised that the scoring system works that way....

It means even if I am an ASIC miner if I have an outage of 90minutes due to a storm then I lose all my shares value. Everyone else profited from my shares. So down time is my enemy.

How does the score system work? (I am sorry for my ignorance!)

----------------------

The thing that came to mind though is the following after being surprised by this part of the score system:

If I run really high difficulty shares...let say 512...and I therefore submit larger shares but less frequently...is this the reason why I earn alot less?

I noticed if I submit very low difficulty shares with a very high frequency...my score seems to stay very low (closer to 100 than 1 billion. Yet, if I submit shares at 512 difficulty every minute, my score goes into the hundreds of millions over time. I assume from watching this that my delay in submitting very high difficulty shares is actually hurting me in my score. Is this correct? If so, then this deeply discourages using high difficulty...right? I can see this turning into an ASIC-festival of people submitting diff1 shares. With BFL coming out and delivering (a minute amount) of ASICs...I assume this is going to be a bandwidth problem in the future, correct?

I eventually decided to run at diff-1 because the super short rounds didn't give me much of any chance as an ASIC to submit the higher difficulty shares.

I find myself scratching my head as what is the right thing to do. It seems to discourage any lapse in submitting shares, even if only a minute between submissions.

I also understood that a low score in 4 digits is better than a high score in the billions. Correct?

The score should be high i'm pretty sure. But as was said at some point in the recent past periodically resets just do to large numbers (computers can only count so high easily). And the score system sadly has no way of knowing if you have an outage or you just went to another pool for a while. Stratum was slush's answer to bandwidth issues. Your view that everyone else profited from your shares is a bit off too though I'm pretty sure. I haven't read enough on how pools actually work but I would guess that the older the share the less useful it is.

Depends on how long the outage was. Score is an exp function so your earning degrade to 0. I'm not sure how long it takes. I have been thinking listing the shares on the stats page isn't the best metric. Have score and total score would be better since those are what your earnings are actually calculated on.

I know why the functions are there, but its effects do seem a little harsh. Maybe it could be reduced a little? Otherwise those with massive rigs could switch do the opposite of the normal problem, run them on a PPS pool, then they notice its been 45 minutes here switch.

sadly your argument is the opposite of what it's meant to be, you just described the very actions that the score system are trying to deter. And if people were doing that he would have to make the functions even harsher.

All backends seems fine, I'm not aware of any problem. Also most block rewards are fine, so there's no indicator anything is wrong with the pool. I wouldn't be surprised it is yet another routing problem on the internet, as I saw many times in few last weeks :-/.

Although I have an office near the explosion place, I'm fine!

17759    2013-04-30 01:20:57    5:01:48    34198356    208898    0.00000000    233836    25.46175733    84 confirmations left

Seems 17759 is also pretty odd. I have 208898 shares but zero earnings. Is that normal?

How long would it typically take for you to generate 208k shares? if it's significantly less than 5 hours that would indicate a connection issue at the end of the round which could cause it, otherwise it's probably a miscalculation.
I was disconnected towards the end due to a strong thunderstorm passing over the area.

Does this mean if I get disconnected towards the end I don't get anything for the shares I produced?

The general rule of thumb when it comes to starting your own pool: If you have to ask the question, you shouldn't do it.


Yeah but everyone needs to start somewhere. I'm just looking to mine with multiple computers instead of one.

And unless you are meaning 1000's when you say multiple you are best off joining a pool. And even then you probably need to hurry. Not that it can't be done or that you can't find a block yourself, but it's very unlikely.

Just my chip in on the earnings during the database downtime.
I actually thought i wouldn't get anything. Was mining on an ec2 voucher (*i've another ($100) which i'd take offers on (one per account)(apologies for the shameless plug)*) and it ran out mid-down time. Of course when slush said he'd pay out based on performance as soon as things are up... and i knew i wouldnt be mining...
So I was extremely happy to log in and see I had been credited. I want to thank slush for his dedication and getting things back up so fast!

On a side note theres a newbie who's about 10% under though from my maths. Might be worth looking into
https://bitcointalk.org/index.php?topic=187689.0


Was it profitable? What kinds of spec did the instance have?

I find EC2 specs to be the most confusing opaque metric there is. Other than comparing one instance to another I have never figure out exactly what their values mean.

I found then answer to this part of the tutorial. You need to login in to the wallet in online mode then go offline and relogin, then you can get to the export after making the new wallet. Now i'm stuck on the deleting the private key part.

Im using BAMT and the old getwork protocol.  What would be the easiest way to get this stratum compatible?  

The proxy?  I tried that when it came out, but I couldn't get it to work.  I tried to put it on a windows machine and then point all my BAMT machines to the proxy, but that didnt work.  After some more reading this morning I realize that I need to install it on each BAMT machine.  Is this the case?  Im not sure how to do that...  I found some posts saying that it doesnt work well with BAMT.

I could also try to upgrade my miner in BAMT right?  I found some instructions here, https://bitcointalk.org/index.php?topic=127622.0 but that is a bit over my head.  Also, the link for the replacement mother doesnt seem to be working.

I'm guessing putting the proxy on each BAMT machine would be the easiest way out for me.  Any tips on how to do that?  I am a novice user.


I used google cache just yesterday to get the updated mother, it's just a perl script. If you can't get it that way I can probably pm it to you or something. If you just copy and paste the lines from that thread on the upgrade it'll work (or it did for me)

When you edit a worker there is a drop down for your expected hash rate, it'll fill that in for you.

I am mining in Slush's pool, and read that I can get "free" Namecoins if I can provide an address.
After doing some Googling, there are posts recommending registering an account on Crypto X Change, but the site has been closed down long ago.
The default Namecoin client doesn't seem to be very user friendly.
Can anyone advice me on the best way to get started with Namecoin?

From what I've read on his site there aren't many being made anymore and he is phasing them out. I think he said only 7% of the pool is still working in a way that generates namecoins.
