Author Topic: Crowdmine PPCoin Pool - Beta Testers Wanted (Read 7650 times)

robotrebellion · « **on:** August 13, 2013, 02:51:11 am »

Crowdmine's PPCoin pool will soon be opening to the public. Presently we are looking to recruit a small group of volunteers (around 10-25) to stress test the server. At this point we are 99% certain that everything is rock-solid, but as always it is difficult to be completely certain without the server having experienced a decent amount of traffic.

Here is a breakdown of the pool's features:

Stratum mining protocol for fewer rejected/stale shares.
Pay-Per-Last-N-Shares (PPLNS) reward system.
1.5% fee - among the lowest!
0.5% block reward - taken from the 1.5% fee.
Security: SSL, DDoS/XSS protection, PIN-protected address.

As a perk for participating in the beta test, there will be a reward of 5 PPCoins for each 200MH/s brought to the pool at the end of the first block discovered.* This is of course on top of the rewards you earn from mining. If you are interested, then please PM me here. *Note: MH/s calculated as an average for the entire round. Maximum of 20 PPC per person. Edit: Round 1 is over.

Hi,

i would be very much interested in beta testing this pool!

PM'd !

crazyearner · « **Reply #9 on:** August 14, 2013, 05:59:02 pm »

nice layout and design, looking good so far just put miner on for a little while

Hey, I might be able to throw like 10GH your way

robotrebellion · « **Reply #11 on:** August 15, 2013, 02:00:05 pm »

alnoor1231, great! Check your PM

The beta is going great so far! The pool has 0 stales out of 189635 shares. One bug has been squashed (thanks to YeOldeMiner and crazyearner for pointing it out). Yesterday I implemented manual difficulty settings for workers, as requested by crazyearner.

Send me a PM I will take a look. Hopefully it will not steal my rewards like multipool did ...

robotrebellion · « **Reply #13 on:** August 15, 2013, 08:19:10 pm »

Thanks sahkan. We definitely won't steal your shares.

Another update: more stats have been added (user rankings by speed and shares). Block stats will be coming once we have found our first block. Thanks to DarthNoodle for requesting this.

FuzzyBear · « **Reply #14 on:** August 16, 2013, 12:22:27 pm »

i request that we find our first block soon please

though may be here a while with the current hashrate :/

You got it. I will have that done by the end of the weekend.

Hear, hear!

Thanks everyone for all of the great support and constructive feedback so far!

robotrebellion · « **Reply #17 on:** August 18, 2013, 01:17:20 am »

Based on feedback and some discussion, we've decided to change the fee structure and # of confirmations. The fee will now be 1.5%, which is competitive with other PPC pools. In addition, 0.5 of that will go to the block finder. The number of confirmations will now be 520.

crazyearner · « **Reply #18 on:** August 18, 2013, 05:10:45 am »

hopping back on

had few ups n downs lately but sorted them out

alnoor1231 · « **Reply #19 on:** August 18, 2013, 09:51:19 pm »

Mined on this pool for bout 2 days and nothin..... Best of luck ppl.

sahkan · « **Reply #20 on:** August 19, 2013, 05:34:41 pm »

Can we get a status update on the pool? It now shows 1 block found but no rewards were assigned per submitted shares. Has all this been worked out? And what is the block number that the pool found?

Hey guys, I wanted to introduce myself. I am another person that is working on this project with robotrebellion. First off let me say thank you for helping us beta test and find find potential issues. Without community help, we can't make this a success to help the community.

So here's the update and our status: We identified a key issue that prevented found blocks from being submitted to the network. As we wrote a significant portion from scratch, this is exactly the sort of things we needed some hashing power to detect. We diligently worked at identifying the cause, and correcting it properly. We have everything working and submitting properly now, and because we want you to be confident that we are approaching this project professionally, we've credited your accounts using PPLNS for one block's worth of PPC out of pocket. Those owed bonuses (block round bonus, and the beta first-round bonus) have also been credited."

As I noted before, we are really wanting to make this project available for the benefit of the ppcoin community and we appreciate your patience and help in seeing this through to success.

I hope you realize it cost me over 2BTC to beta test with those miners. Let's be 100% sure that we can actually mine something before we get all the miners on there.

I just posted in "Features Requested" on the pool but I can't see that topic... Is it hidden?

It is unfortunate that you incurred losses. I hope that having paid out of pocket for one block's worth of PPC (+bonuses) we have made at least some restitution. I agree, let us work out the kinks before you migrate all your workers to the pool. I am expecting that the next block we discover will go smoothly and restore confidence.

I see the topic and have responded. Great ideas! I love stats too.

I lost my confidence in basic functions of the pool. But I tell you what, I think we need to apply ourselves to the innovation here: My 80GHs miner makes .8BTC/day and I don't think you have enough hashing power to test the pool so to split the risk for .4BTC I will retest the pool for 24hrs (I risk .4 & you lease the miner for 24hrs). If all goes well you move out of beta and announce the pool. We need to do it fairly quickly because BTC difficulty jump will cause the ppcoin hash rate to sky rocket again.

seems fair for someone with the large hashing power.. split the risk etc, and would allow u to verify the pool fully working with that amount of hashrate on it.

The avalon is back on there. We should find around 2 blocks in 24hrs. BTC has around 611 blocks before it all goes crazy again.

Good news everyone!
We have just found a block and everything has gone smoothly as expected!

Here it is on block explorer.

Congrats to sahkan for finding it!

Looks like we are finding blocks now. I just don't understand the pay out system. Can someone explain it?

robotrebellion · « **Reply #31 on:** August 22, 2013, 02:50:11 pm »

We use a Pay-Per-Last-N-Shares (PPLNS) reward system, where N is set at 2*Difficulty. The basic method is this: When a block is found, payment is given to shares in a window, starting with the most recent share submitted and going backwards up to N. Shares older than this are not paid. So if difficulty is 1 million, then the most recent 2 million shares will be counted.

PPLNS does away with the concept of "rounds" and miner rewards are instead determined using a moving time window. As you mentioned on the crowdmine forums, this is similar to BTCGuild's concept of "open" and "closed" shifts. PPLNS was originally proposed by Meni Rosenfield, and Meni has gone on to compare it with other reward systems such as PPS, ESMPPS, DGM, etc...

FYI: We're updating to a new SSL certificate. If you see a message about a certificate mismatch, then that's why.
