Title: Bitparking PPCoin Pool [closed]
Post by: doublec on September 11, 2012, 03:01:19 AM
Pool closed, sorry. From the pool page:

Quote
I regret to inform that I've decided to close this ppcoin pool. With the large recent increases in PPCoin price and the variance of finding blocks with the ppcoin network combined with the 512 block maturity time it's become to risky for me to keep operating. In the last few days the pool has lost 10,000 PPC out of reserves and I'm not willing to fund out of pocket at the current prices. Thanks for mining here and I recommend coinotron.com or vpool.us. Withdrawls remain enabled for a few days and then I'll automatically withdraw to all user addresses.

The variable difficulty stuff is only recently implemented so if you see problems let me know. I haven't enabled that on my other pool yet but I will do once it's seen a bit more testing.

5000 Shares

5000 Shares
0.10867260/share (97.5% PPS (fee))
1PPC = 0.00017504/btc (Current Sell Price)

PPC: 5000*0.10867260= 543.363PPC
543.363PPC*0.00017504=  0.0951BTC

5000 BTC Shares = 0.0928BTC
5000 PPC Shares = 0.0951BTC


That is why the pool is popular doublec. Once it drops in profitability your hashrate will begone. At the moment mining PPC makes you 102-103% BTC.

That's working on the assumption that price stays the same. It looks like there's a lot of folks mining PPCoin so my guess is that the price may well go up.

Either way it'll be interesting to watch :)

Yep, the same thing happened during the early namecoin days. People would hop to my namecoin pool when the namecoin price reached a point where it was more profitable to mine them and sell for bitcoins. I'm expecting a drop in hashrate when the price drops. Unless people start using PPCoins for something of course. Some will remain interested to see what happens with proof of stake as well.

Hey doublec, check your PPC exchange.  It looks kind of weird in that I don't think the "Sum (BTC)" value is showing correctly for certain Buy orders:

0.00020100   10000.00000000   2.01000000
0.00020000   10000.00000000   4.01000000

Title: Re: Bitparking PPCoin Pool - PPS, Variable Difficulty, Pays Invalids
Post by: Shadow383 on September 12, 2012, 10:31:49 PM
I've started a PPCoin pool. It's based on the merge mining pool I run  but doesn't merge mine, it only mines PPCoin.

  • URL: http://ppcpool.bitparking.com
  • Mining Port: 20098
  • Pay Per Share (PPS)
  • Instant Payout
  • Pays Invalids/Orphans
  • Miner can select difficulty
  • Simple registration. Just set your username, coin addresses and mine.
  • Block/User stats (http://ppcpool.bitparking.com/blockstats)
I've kept everything deliberately sparse. Coin addresses can't be edited once created (by design) but you can register a new username anytime with new addresses. This is to prevent unauthorized people modifying addresses.

Large hashrate miners can choose to set their own difficulty to mine at. To do this set your password to be "d=8" to mine at difficulty 8. Change '8' to any number less than the current PPCoin difficulty. Your payment per share will be that 'd' value times the PPS value listed on the site.

PPS value is calculated as: (current block value) / difficulty * 0.975 which is a 2.5 percent fee.

When proof of stake starts working I'll investigating paying out proof of stake rewards based on user balances.

Do you think you can handle ~65Gh/s?
I may be pointing a whole ton of hashrate your way in ~12 hours  :D

You were right, seems to be handling it just fine, ~0.65% rejects so far, versus 4.2% over at http://ppcpool.us.to/  :)

Coinotron (http://coinotron.com/coinotron/AccountServlet?action=home) has difficulty and profitability. Bitcoin miners work. Reward is linked to difficulty. The higher the difficulty, the lower the reward.

You'll see a change when you submit a block successfully. Check your username is correct and then you use the correct uppercase/lowercase letters.

RIght. About the only things still low enough in difficulty that a CPU will get you any are BBQcoin and, to a much less extent, GRouPcoin.

-MarkM-


Title: Re: Bitparking PPCoin Pool - PPS, Variable Difficulty, Pays Invalids
Post by: markm on September 22, 2012, 08:40:01 AM
GRouPcoins are part of the Massively Merged Mining (https://bitcointalk.org/index.php?topic=102661.0) array of merged-mined coins, so if you used that pool you might do better than simply directly mining GRouPcoins yourself because your hashing power would get you a share of all the altcoins, expressed as (and converted into) DeVCoins, plus hey you never know it might even get you a fraction of a bitcoin eventually (as it actualyl is a p2pool, so you are mining bitcoins in distributed p2p fashion while also merged-mining the altcoins).

I added a new hardcoded checkpoint to BBQcoin recently since it is so low difficulty it could easily be 51% attacked again, my new version is in the BBQcoin directory of my sourceforge file-downloads site http://sourceforge.net/projects/galacticmilieu/files/

BBQcoin is like litecoin, it cannot be merged mined, even with litecoin, and aims to be CPU-friendly, which, right now, thanks to not currently being mined by folks using GPUs, it is doing a better job of in a way (that way being, hey with CPU you can still mine the stuff right now).

(After people attack a coin, it seems, they tend to go rest on their laurels afterward instead of keeping up the attack forever, so often after such an attack is a good time to get in and get some coins while they pat themselves on the back for having "killed" it...)

As to price, why, they are priceless! ;) :D

GRouPcoin are traded on the Digitalis Open Transactions server (https://bitcointalk.org/index.php?topic=53329.0); BBQcoins I have not set up there yet as I am waiting to see how they survive over a longer period of time before worrying about trading them.

It seems like PPCoin doesn't have the standard difficulty level as bitcoins. The difficulty becomes higher if the total hashrate of the net go higher. (At least it's what I understood about PPcoins).

The first post says the pool uses variable difficulty that you can set by using certain settings in the password field when you login to the pool...

I just don't understand it because it says to use any difficulty less than the current difficulty (which is in the thousands) and the example used in the first post was "8" as the difficulty. So I am looking for an accurate, detailed description of setting the difficulty for the ppcoin pool at BitParking, preferably for a minerd .bat

PPCoin has the same difficulty for the proof of work blocks as bitcoin. As hash rate goes up, difficulty goes up.

When you mine on the pool you mine at difficulty 1 like most bitcoin pools. If you have a very high hashrate you might like to mine at a slightly higher difficulty to reduce network traffic. You can do this by following the instructions in the first post. Set your password to "d=x" where "x" is a number. "x" can't be higher than the current ppcoin difficulty as this would make no sense - you'd be losing money. You don't have to do any of this though if all you want to do is mine at difficulty 1.

Just a quick suggestion doublec,

You might want to truncate the found blocks list in the pool data page, it is turning into an awfully long webpage.. :)


Maybe just keep the found blocks in the last week, and a link to the rest of the list if somebody wants to see it.

I like the instant payouts, but would understand if you held my funds for 520 also.

*If* you do something around mining for stake, would it make sense to leave funds in the pool or your exchange or will it matter?  I'm asking because I think moving funds would reset the 30 day hold time required correct?

Yes moving funds resets the time. I'd be more inclined to add proof of stake incoming earning to the exchange first. An interesting approach would be a "proof of stake pool" which would really be an online wallet but optimized for ensuring fund movement minimizes effect on coin age.

For passing on PoS rewards to users, I was thinking you could allow them to set a PoS balance value/% which will lock up that amount of coin for use in PoS, then you pay out PoS blocks proportionally based on these balances?  But seeing as the reserve balance feature is a config item and ?not dynamically settable? this may not be possible?

Setting the reserve balance does not change the ppcoind coin selection aglorithm. So even if I dynamically set the reserve to the level of the sum of all users selected reserves, withdrawals can come out of the high coin age balances unfortunately.

A simple and effective way of doing this is just dividing the coins across separate wallets. The larger volumes you are dealing in the more wallets you would want to use.

Say you choose ten wallets, order them in terms of priority, 1, 2, 3, ..., 10.

Divide your current stock evenly across the 10 wallets. When you payout, use wallet 1 first, and then move to wallet 2, ...

When coins come in, allocate them across wallets in order to maintain a target ratio of 10% of coins in each wallet. i.e. usually you add to just wallet 1, but if the allocation in wallet 1 exceeds 10%, then divide the coins evenly across wallets 2-10.

All the bitcoin online wallets should be doing this anyway, so they can keep say, wallet 1 as a hot wallet, wallet 2 as an offline wallet, and wallets 3-10 locked in a safe.

How frequently the wallets need to come online to mine depends on how predictable inflows and outflows are. The less predictable, the more frequently you should bring wallets online to mine stake.

Have you considered making this a merge mined pool as well since it sounded like from other posts you could do merge mining with this coin as well so long as it is the primary coin?  Could prove interesting and I'd like to try that out for a little while at least depending on how pp matures.

There's been some server instability over the last few hours due to a large number of individual miners connecting. I've made some server adjustments and will be monitoring it.

Here comes suggestion to pool owner:

Increase fee to 4 or even 5%

Bitparking is the only pool where one can easily mine 4 different coins simultanously! I totally doubt miners would complain if you would
use extra money earned from increased fees to improve stability of server or whatever else is causing dropouts. Heck, maybe you get enough
money to add Terracoin or some other currency to those 4 you already support!

I can help you with designing killer-looking but low resource consumption website if you decide to upgrade the look of current one, which IMO
would get you more miners.

I have a sneaking suspicion that doublec has more than enough skillz (that's right with a 'z' :-) lol) to create a pretty awesome site, I just suspect he opted for simplicity (see mr. doublec's tech blogs etc. he seems very technically knowledgeable)  As far as the fee is concerned, that would not be beneficial as the competition for pool members is pretty intense and his pool while offering the gold standard in alt coin merge mining still sadly has only 1 card to compare for most miners and that is BTC.... so he could at this point compromise and say make BTC 0% or very low % while upping the % fee on the alts to make up some of the difference but that's up to doublec and how he wants to get fair and proper payment for his outstanding pool (which I will hit with asics as soon as they ship :-) which should be interesting to see given the relatively low hash rate of some of the merged alts...)

Help Help, newb forgot how to mine!

Sir,
I am having an issue and I am not sure where to begin. Picked back up mining ppcoins with you and my workers are registering MH/s  (28-30ish each) but are not showing any payout. GUIminer is showing accepted shares and a few invalid. I am at a loss on what the problem is.

Anyone have any suggestions on where my problem may lie? I am at a loss.

Thanks!

Why did you increase fee to a HUGE 7.5% on PPCoin? 2.5% was much better, now you're just being greedy. Please revert this ridiculous fee.
With 7.5% of 550 ghash, you're making in the area of $1500 per DAY by doing almost NOTHING.

Please, dial back the fee. You are being greedy.

I think coinotron pps fee is at 8%, the pool ops are probably doing this because of the long confirmation time.

Due to orphans, stales and the instability of the ppcoin daemon there is a lot of loss that the pool absorbs. My PPC pool wasn't designed for huge hash rates like it is getting now and it's causing a large strain on the server. I've increased the fee to account for this and to discourage miners from using it - preferring them to use cheaper pools and reduce the load. When PPC supports getblocktemplate I can switch to using stratum instead of getwork and the pool can lower the fee. I do recommend switching to another pool if you're not satisfied.

With the 500+ block confirmation required with PPCoin the pool requires a large buffer. The pool reserves keep dropping low and I'm funding out of pocket to keep things topped up. I was fine with this when prices were low and I didn't mind spending 'hobby money' levels to keep it going. Now the costs are much higher and the pool needs to pay for itself.

Does anyone happen to know why the reported rate on my user stats is less than what's shown by either guiminer or cgminer? My 7950 is showing about 540MHash/s, while my stats page has been sitting between 460 and 480.

I've had a few rejected shares in cgminer, but none fail due to hardware errors (none reported anyways).

Thanks in advance!

Even with the fee increase the pool has hit a large bad luck run and I've decided to close the pool. The risk is to large to end out of pocket and having to buy ppcoins to cover the reserve at high prices. The following is posted on the pool page:

Quote
I regret to inform that I've decided to close this ppcoin pool. With the large recent increases in PPCoin price and the variance of finding blocks with the ppcoin network combined with the 512 block maturity time it's become to risky for me to keep operating. In the last few days the pool has lost 10,000 PPC out of reserves and I'm not willing to fund out of pocket at the current prices. Thanks for mining here and I recommend coinotron.com or vpool.us. Withdrawals remain enabled for a few days and then I'll automatically withdraw to all user addresses.

I really hope you'll consider a PPLNS (or RBPPS?) pool. I'd launch one myself if I had a bit more clue on how it all works. I've been out of programming and web/database development for ~13 years, changed careers. Been fun starting to mine though. But my only PPC pool I'm using now is Coinotron and they keep going up and down, wasting lots of gpu cycles. Gotta get a 2nd pool. :)

protip: open a second instance of cgminer for BTC.. run BTC at intensity 3 and PPC at intensity 11... when PPC is up you'll only get a few mhash devoted to BTC.. but when ppc is down you'lll get 85% hash rate on BTC

Great idea, thank you. :) What I ended up doing was starting up a local ppcoin server and putting into cgminer as a second pool in load balance mode. So in theory I'll solo mine if coinotron is down. In theory...

Speaking of which, can I have pools for multiple SHA-256 coins in cgminer at the same time? I'm guessing the longpool/stratum notifications would mess that up. Like say, if I added a PPC and a TRC pool, if it'd individually work on the work units assigned without any weird issues.

It is my own front end and back end. The back end is written in the ATS programming language (http://www.ats-lang.org) and the front end in the Ur/Web programming language (http://www.impredicative.com/ur/). Thanks for the payment point I'll take a look.

Man, so many new languages I've never even heard of, lol. I'm obsolete. Everything I ever did was in C, C++, PHP, or Perl. Touch of Java. Never learned any Python.

I like how your system doesn't use a password, just links to a hash you can't change. The Eligius guys take it a step further and your payment hash is your username, no pw or accounts.

I'm a bit of a programming language nut. The pool was originally written because I wanted to try out the language runtimes and see how well they worked.

I used to do what Eligius does too, back when 'mmpool' wasn't merge mining but was a namecoin pool. When I switched to merge mining I had to somehow associate multiple addresses with a user. When I did the ppcoin pool I used the same pool code after I'd done the user modification thinking that sometime in the future I'd enable merge mining with ppcoin as the primary chain but I couldn't get that working.
