[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

[miningfever]

Hi,

I just created a very simple script (php/mysql) to track my personal progress on the pool, fetching the data every 30 minutes. I want to use this for some detailed after the fact ROI analysis.
However, I noticed that not all fields that are visible on the stats page are provided in the JSON response from the API. Would it be possible to add these?

The fields I am interested in are the following (I am using the personalized API with an API token).

For blocks:

• My Shares
• Block value, including TX fees
• The slush block number, although not really relevant I would like to add it just for reference purposes

For the pool itself:

• The current difficulty

That would really help!

If anyone is interested in the script: currently it does absolutely nothing but fetch the data at a regular interval (cronjob), and it is by far the ugliest piece of code I have ever written (in 30 minutes) , but it does the job.
I'd be more than happy to share it with you if you want, but don't expect anything fancy just yet!

Another member - Sunriselad - beat you to it and created a utility to do most of this.  It's called Mine Minder, and includes the block values, pool hash rate, and current difficulty.  It also displays a current bitcoin value, but I do not know what the source is.  It does not include the Slush round number.  Apparently there is some difficulty in getting the individual shares per round into the feed.

I have my copy set to download every 300 seconds (5 minutes); I believe the default is much lower, which would seem to impose an unnecessary burden on the servers.

You should be able to find the relevant post on the forum.

[Edit] try post #8211 on page 411.  Discussion follows, and there is a later version than the one mentioned.

Hi everybody,

I used to mine some BTC back in 2011 on miningcz.
I tried to access to my account (n0name, same login as here) but it seems it's not working anymore.

Since the miningcz administrator might be somewhere in this topic, can he have a look and give me a feedback how i can have my account working ? (i try the online chat but i didnt get any answer)

21027 and 21033 need recalculations, my reward is halved again.

My reward for round 21027 is 1/100 of the usual one. But it has been confirmed already... :-(

+1 - The same here

+1 here as well.

So what is the story with how to get this resolved? I've sent an email, there are several posts here reporting the problem, and I've tried IRC. The actual BTC involved here is negligible, but it isn't confidence inspiring that these problems happen *and* then don't get resolved. Looks like slush hasn't logged in here in over a month. How is one supposed to file a support ticket request with him exactly?

Thanks for the info Sir Alan, but the program you are referring to requires windows. Although I do work on a windows workstation daily, it's not on 24/7 but I do have several linux VPS's running 24/7, which is why I wanted to use php/mysql. Also, I'm not sure if the windows app just shows live info, or actually collects and stores the data for later use. My intention is to store the info in my own database so I can use it to do long term ROI calculations. Something that tells me over a longer period of time what my daily revenue is, minus hardware costs etc etc. Kinda like the online calculators you can find everywhere, but then specific to my hardware, slush's pool, and not as a a forecast, but looking back.

Maybe a forecast would be a nice to have so that I can predict how much longer my hardware remains in the money, but I'll have to see how much time I'm willing to spend on this!

Well, if you don't mind writing ugly code <grin> then think this would be doable in a macro for calc (apache openoffice) to snap your html stats page every so often and extract data from new rounds since last query -- could also grab your account page to check on worker health.  Another macro to run the ROI stuff, another macro for any statistical analysis you might want to do, and a macro to merge current data into your mysql db if you decide not to keep it in calc.  This approach would also be more or less OS independent.

One question:

Under "Payout History", my Total is 0.14; however, if you add all Amounts paid, it's 0.13. So, my question is, has anyone noticed it? Do your Total match Amounts paid?

I suspect that it is just a rounding error induced by only using 2 decimal places.

Thanks, Trongersoll! Always good to hear from a trusted source.

Slow day in the mines today, like watching paint dry zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

We are overdue for a few short rounds...

Any news? Or is this just the cost of mining on slushes pool?

Pretty sure some people got a larger than deserved reward on that block, not sure whose pocket all the shorted BTC will be covered by but I'd say it's spilled milk by now...

Could we mine namecoin also with bitcoin in slush pool as it used to be?

What is the point it is not there?

https://mining.bitcoin.cz/faq/#namecoin

Namecion merged mining had been only implemented in the (now) obsolete getwork protocol. Since getwork isn't supported any more, namecoin merged mining has been suspended too.

[edit]
This question has been answered multiple times in this thread. Please do consider one simple search before asking next time. Thanks in advance.
:-)

[edit2]
Even Slush's post on this topic can be found where he explains his motivation why he is not implementing namecoin merged mining in the Stratum protocol, and his attitude towards namecoin in general.

[nov]

If NMC is used in: BTC-E, Cryptsy, Vircurex, Crypto-Trade, Kraken, Cryptonit, Coined Up exchanges?

Why not to mine them for free with bitcoin to exchange?

You simply trust slush.  It usually works out.  Slush is god of mining pools.  He's a busy man.  

In all seriousness, problems on slush's pool usually just fix themselves without a word from our glorious leader.  Slush keeps it pretty business like.  BTC in, BTC out.  No talky.

Slush does not get enough credit for saving bitcoin by introducing and designing pooled mining.  Well not save bitcoin...but certainly his creation of the pooled mining system worked and here we are today, with a decently decentralized mining crew.  Without old slushy, life would be pretty different.  So we try to give him a break around he because he gave us all life.

This is a bug that has been here forever.  It fixes itself.  Don't sweat it, trust the father.

Wow, what a round we're stuck in!

[gourmet]

(...)
Slush is paying more for the freshest calculations and much less for the older results.
So if the hashes are not getting to the pool before the block is found, then they will not count towards the payout. (The pool thinks you are skipping).
Late arrivals are not counted.

I agree but I also think there is a chance "late arrivals" may very well count towards the next block. I will see a low payout and the next block sometimes will make up for it as I thought the late shares get credited towards it?

Quote from Slush's Pool:-

How does bitcoin pool work?

Our server gives users blocks of very low difficulty to solve. Each solution found is registered as one 'share'. Occasionally, a solution will happen to also meet the full-strength difficulty requirements of the Bitcoin network, resulting in a successful 25 BTC minting.

This 25 BTC is divided among all of the users that contributed to that round, weighted by the number of shares that they earned. Therefore, the reward earned by a given user is given by the following formula:

(25 BTC + block fees - 2% fee) * (shares found by user's workers) / (total shares in current round)
Shares do not carry over from one round to the next. When the pool mine a block, only users who worked on that block are rewarded, and only for work they did on that block. This is an unavoidable consequence of the way that Bitcoin mining in general works.

Late arrivals go in the bin

More generally, only useful work is rewarded. That means, if you happen to make a late submission for any block, not just the one found by our pool, your share will get refused and won't count. Simply, when the network finds a solution to the current block, everyone has to start new work on a/the* new block. The new work is different from the previous one, so there's no reason for rewarding late submissions.

*)
"A" new block from the network's point of view. Any pool operator / solo miner can create its own block from any of the transactions in the transaction pool.
"The" new block from the miners' point of view. "The" new block is created by Slush (his bitcoind) and we can't influence its contents.

Well, if you don't mind writing ugly code <grin> then think this would be doable in a macro for calc [...] This approach would also be more or less OS independent.

LOL, I do intend to clean up the code once I start creating the stats; right now it is just pulling in the data every hour and storing it in a local DB so I can add the stats whenever I want; at least I will have access to my historical data.

Also, php/mysql should run on most (if not all) OS's, so I would argue that it's pretty OS independant; it just may take a little more time to set up. Another advantage for me by using web technology is that I can host my stats page somewhere and access it from anywhere. I could even add some fancy notifications (email, sms, whatever). I know many apps exist that do similar things (I'm currently using the Miner Status Android App), but I like to have 1 nicely integrated app!

ps. this is a loooong round... (11+ hours)
