[350 GH/s] "Eligius" (experimental) pool: almost feeless PPS, hoppers welcome

[Artefact2]

how 'bout it, luke, wanna try this first, before you put a fee?

Like I said, I'm not putting a fee. And there's no easy way to figure out the overall pool costs. Hence, it's ok if people just donate what they consider a fair amount every once in a while.

you really should go for a small fee like you said. that would still be much better than the competition.

the problem with donations is that only the good guys pay. and because of that I do not want to donate any more and thus become a bad guy myself >=)

Should I remind that the pool already keeps all the tx fees ? It's not uncommon at all to see blocks found with > 0.1 BTC fees (some even have > 0.3). So, in the long term, the more hashpower the pool has, the less need for a fee there is.

FYI, after a week of testing on Europe, I have calculated that a patch I wrote decreases duplicate work by 0.7%. Given the current pool size of 60 GH/s, that means we now (once I apply it to the USA pool) accomplish a whole 420 MH/s extra than an unpatched bitcoind, or almost 1 BTC per day at the current difficulty. Even half of that, 0.50 BTC per day, would take only until the end of the current difficulty to cover the expense of the time I spent writing the patch.

In my mind, this would justify adding a long-term 0.7% "fee" to the pools, but I'm not going to do that. Instead, I'm going to just publish the information and ask everyone to keep this fact in mind when considering donating to the pool.

You're a great guy.

I'm going to give the pool a 1-2 day test run.
I hope I can figure out the stat page to check progress after some hours.

idea: take email address as password, send periodic emails (on block solves and payment sent)

If, then please only optional + with unsubscribe feature (as this might be an easy way to spam people by subscribing them via this system to a mailing list)

except we've finally invented the proof-of-work-to-spam system. You have to mine to spam them. And the spam isnt very interesting.

It'd be great if spammers joined the pool to spam out block solves and payment information, and contributed GH/s to the pool! not likely tho..

maybe "-- This payment info message brought to you by [1a|_iS!!!!"

lol.

US MySQL is taking forever to add an id column. Europe should be fine in the meantime.

MySQL? What are you using that piece of shit for? I guess it's simpler than Postgres.

SRSLY, responsible financial institutions use postgres. It's a question of how serious
your local bank-pool is about transactions!

Then again, replication between nodes is a lot easier with mysql, at my last look. Could be better now in pgsql...

I'd probably use Postgres if I knew it. But MySQL has phpMyAdmin, so... I did consider switching anyway when the MySQL people told me I couldn't do replication that wasn't 1:1, but then the Postgres people said the same thing.

Stats are being moved to http://eligius.st/~luke-jr/raw/ but it isn't done yet.

phppgadmin - web-based administration tool for PostgreSQL

course, real men just use really huge xterms instead and alot of scrollback...

[mathx]

In the meantime, the stats main page has been improved : there's a hashing power graph and a list of recently found blocks. Check it out here !

Edit: done. I had to reset the individual graphes, but this time should be the last.

Awesome page!

Do you have a hashrate distribution diagram? Like showing the statistical distribution and stddevs for the population.  That'd be interesting to see. Also would be interesting to see is the movement overtime of 2std devs or so of the hashrate population above and below the mean, graphed over time. This will show how fast the pool is increasing its power per individual contributor (not that contributors cant generate more addresses for themselves to mine with..)

Awesome work thanks! Soon as I have some BTC's ill start donating lol.

That's a great Idea. Artefact2 could add some calculations for the individual stats like "The Patch written by Luke-Jr resulted in approx. XYZ more BTC for you since you've joined Eligius. How about donating a part of this for the Pool"

Payouts of 1.0 BTC might be a bit high.

Someone asked 1BTC or once a week (once the credit is a week old? pool credits from the week? dont know), but 1.0BTC has exploded over the last 6 weeks and is about to get a lot higher.

Of course it's an odd thing - soon it will be downright a waste of power and real money to use anything < 10-20MH/s, if it isnt already (unless it's people at work or school leveraging employer's/school's power lol). Im just playing around with BITCOIN and dont have real gear here, a whole 30-35MH/s woot lol. (possibly not economically viable with airconditioning on in the summer...)

If the market keeps climbing like it is, it's quite possible to asymptotically never get paid - until you stop contributing to the pool. That's a strange incentive to provide to pool members - to leave the pool!

Unless it keeps load on the server down by not having to service pissant miners like me - a nice incentive to GTFO and let the big boys do the real work?

Just wondering whats going to happen when the minimum payout of 1.0BTC is on avg 50 6990's running for a month and is worth $1200 USD. (Sorry thats a top of my head guess, i could be off by a magnitude or 3 -- there's some relatively linear range of values for difficulty:$USD exchange rate on mtgox, bitcharts has the data). You get what I mean.

perhaps payouts should be when they're equivalent to one USD according to MTGOX or average of the largest 3-5 exchanges or something.

Feel free to base it on Euros too, or some basket of currencies. Maybe we should base it on the price of oil, since electricity tracks that somewhat too... lol. Economics 101 fun!

really, it should just be based on the current difficulty, relative, say, to what 1 BTC:cur difficulty is right now. (434883, for reference when this topic is another 3-6 weeks old...)

I had problems with phoenix when I first joined. Might be because I was using bare 1.4 and didnt patch up to 1.46 or 1.47 (.48?)

ufasoft was working fine with shares, but this is what i got with phoenix (runing at the same time):

I stopped it and ran the regular pcolbm miner instead at nearly the same rate.

(however I just got this on it:

Code:

is that normal?!)

Phoenix 1.48 shows in slow mining mode (~9 MH/s) also a LOT of stale/"rejected" shares (15 out of 16 currently). My guess is, that with more than 1 phoenix instance long polling does only work for a single instance...

If this happens with only a single miner too though, the error must be somewhere else.

Is the EU pool actually working? i know it says it is but 1 block in 7 days is VERY unlucky

[Inous]

I've been mining for over a 4 days now on eligius and I still havent seen a drop of bitcoins.... what gives? I realize I'm mining with a really bad GPU (GTX 258) and getting only 60 mhash/s but shouldn't I atleast be getting SOME bitcoins? like some change? I have a high number of stales too 196 at the moment, but I have 4,383 accepted. Am I misunderstanding how bitcoin mining works? Should I even try to mine with 60 Mhash/s?

[Bitcoineruk]

If you are on the EU server, then you wont recieve anything, purrely and simply because they havent found a block for ages

If you are on the US server, you would have recieved something by now

[Inous]

can you give me the url to US one just to make sure I'm on it?

[Sukrim]

Use the wiki, d'oh!

Someone asked 1BTC or once a week (once the credit is a week old? pool credits from the week? dont know), but 1.0BTC has exploded over the last 6 weeks and is about to get a lot higher.

I will, of course, gradually drop the minimum as the value comes up. The main point is to save you the transaction fees when you go to spend them.

[Justsomeforumuser]

Using the artefact2 stats, at some point during today the estimated reward reset from an already too small amount(was getting a rate around 40-60% of what I earned on slush) to zero and has now remained zero despite continued mining throughout the day.

Where am I able to check "for sure" what I've "earned" so far?

Or is this an issue of amount of share value only being able to be determined once the current block gets solved?

Does that in turn mean I won't know how many BTC per day I make until we find another block despite continuously earning shares?

You get paid out when you hit 1.0 BTC _AND_ a block is found to pay people out from. We're still finding blocks regularly, so its not too long to get paid out.

As for worth mining with 60Mhash - check the mining calculators for your cost of power (dont forget to x 1.6-1.9 if you have to run AC too) and if you leave your computer on anyway (take away that base power level from your increase for bitcoin to find the extra power and its cost) -

the only thing that determines value of mining isnt the difficulty, it's your ratio of MH/s to the whole market indexed against the value of a BTC in USD or other.
It floats up and down between worth it and not for any particular rig.

There's definitely something seriously wrong with Phoenix. Perhaps someone should ask the author to figure out what? :p
