Stay away from Bitmain!

The official announcement from thei www...

"UMISOO Minerals mine equipment maintenance outage will be a temporary power outage, I'm sorry, this will give you an early loss, we will give you compensation at the end or the next."

2 Emails from webmaster

Hello, I'm really sorry! Summer to come, need to re-deploy mines to facilitate mining machine of heat, which can increase the life of the mining machine operators and improve strength. We also carry out mining machine maintenance cleaning. In the end, we will give you appropriate compensation, I hope you can understand.


Best wishes! Umisoo 21.3.2015


Dear User,

We are so sorry to inform that your miners have been turned off due to the relocation of Umisoo's mining farm. The new relocated mining farm is owned by Bitmain, while it is no longer suitable for the continuation of the previous Umisoo type's hosting service, because new mining farm is located in a remote rural area installing with small limited bandwidth, and exporting IP for strict secrecy.


 In order fix the trouble that caused:

1> Umisoo will buy the S4 market from Hashnest.com to compensate the hosted hardware, e.g.: User who owns one hosted S4 will get        2Th/s of S4 market on Hashnest platform.
2> Hosting service fee on Umisoo is 0.11 US$/kWh, while the maintenance fee on Hashnest is 0.0967 US$/kWh.
3> Umisoo will compensate the downtime loss based on 100% PPS payout. Compensation will be issued to your account on Hashnest.
4> Your balance of hosting service fee on Umisoo will be transacted to your account on Hashnest.
5> Please submit your account on Hashnest to Umisoo (webmaster@umisoo.com) to speed the transfer.

Our truly apologies again, Looking forward to receive your reply and move on.

Stay away from Bitmain!

So what does this have to do with p2pool? You sure you've got the right thread for this?

Yes I´m sure. Bitmain folks tell lies to users who wish to use p2pool, they told that it would be possible to change miners settings at umisoo when miners are there. When it arrived they told me that their engineers think that im wrong and i should be happy with alot dead... 30-50% at the time. And now this - lying and....

How much do you think p2pool looses because ants wont submit doa shares?  Or do You think that everyone replaces that not working cgminer with working one? Bitmain works against p2pool.

I'm so full, I couldn't eat another block........

Well, maybe one more......nom nom

It's rain on P2Pool ... 3 blocks in 1 day with 1,5Ph/s 
Luck is the force ! ( http://minefast.coincadence.com/p2pool-stats.php look, the luke column... )

Showers of Gold my friends, yes P2pool is the home of golden showers.

Anybody know what's going on with p2pools.org? Been down for like 2 days now..

[Meuh6879]

... official adress is : http://p2pool.in
and real and strong pool stats is : http://minefast.coincadence.com/p2pool-stats.php

[devlin85]

don't care about the official.. They don't have a list of all altcoin pools, and http://p2pool-nodes.info is just bitcoin.. wah wahh..

I wish there could be some more blocks in p2pool. I have invested everything back to pool and so far so good - ive been gaining more and more with rented power.
One time i did it with only the btc address and didnt get a single share with a one btc, so after that im doing it with /something.
So im gambling i guess, without blocks sofar.

I just wish everything is allright with my configs, because ive spend just over 10 btc now. Maybe next time then with a shiny new btc

Some say its better to have more at once, like its better to have 1 ph for one hour than 100 th for 10 hours.  Is it?

That depends on the phase of the moon.

Yes, luck is luck, but really: Lady luck and her friends are having a good time on P2Pool this week. Another 3 blocks in a 24 hour period....



Enjoy while it is here.

Notice a pattern?   My measly 6.9TH/s (6xS5) is now a small miner.  Top is shares, and bottom is pool hashrate, over a 14 hour period.  I'm sure people can pick this apart, debate luck and statistics, etc... I just thought a good screenshot, somewhat makes a point.

[IYFTech]

This is exactly what I've been saying for months now - p2pool just can't scale properly with the increased hash rate, the more the hash rate - the worse the problem. I only point a few old S3's at p2pool now, & then only when the hash is below 2PH - any more than that & it's wasted.

It's such a shame, really

I guess I'm confused by what point you're trying to make.  If you're trying to compare shares found to hash rate, the only noticeable spike in your hash rate graph happens for a couple hour period.  There is plenty of other time where the hash rate is relatively constant that you're not finding shares.

We all recognize that as the pool's hash rate goes up, so to does the difficulty of getting a share onto the chain, which statistically means you find fewer.  However, it also statistically means the pool itself finds blocks more often.  Let's say you've got your 6.9TH/s and the share difficulty is 6.5M.  Statistically you expect to find a share about every 1.1 hours or so.  Assuming each red spike represents one share, you found 9 shares in 12 hours, so you're a bit lower than expectations.  Also, you can clearly see the distribution of found shares is nowhere near the "one an hour" expectations, but rather is clumped together.

This is exactly what I've been saying for months now - p2pool just can't scale properly with the increased hash rate, the more the hash rate - the worse the problem. I only point a few old S3's at p2pool now, & then only when the hash is below 2PH - any more than that & it's wasted.

It's such a shame, really 

Remember last year (August) when share difficulty topped 10M for the first time?  Remember when it topped 20M a few times shortly thereafter?  That's what squeezes the smaller miners out.  Seeing a statistic that says it'll take you a day or more to find a share... and then hoping your share actually gets accepted and not orphaned.  Basically, as long as your expected time to share is less than the pool's expected time to block you're OK.  When it starts taking you longer to find a share than it does for the pool to find a block you perceive your mining to be "wasted" because blocks will be found for which you receive no payment.

[lightfoot]

True but if you can just hold your gut in you realize it's variance. Sure he could miss a good run, but it's exactly as likely that he will have triple the number of shares when the next single block is found (thus evening it out).

p2pool's problem is that there are two dimensions of luck (shares and finding a block) but really over the long term it is exactly the same luck as say Eclipse or whatever. Now the perception is your's screwed if you are a small miner, but that's only looking at the short term.

A feel-good fix would be cool and might reduce small miner variance, but isn't that what operators like nastyguy do? Provide a place to mine and get more steady payouts while still on the p2pool concept?

Also in order to do p2pool right you have to run the stupid blockchain and a p2pool python thing. That's another problem: The dumb-ass blockchain node needs to be kept up to date and fast otherwise you will lose out with a high stale count. Blah.

solid 2,5PH/s ... new farm launch for monday tested on sunday ? 

[devlin85]

Somehow http://p2pools.com wasn't registered?? It is now   Got a very basic setup going testing out the p2pools. Adding a new coin everyday or so, the ones running have already been tested for days and haven't had any issues.

I've not been active in the bitcoin community for a long time now, just randomly popped in the thread to see what's up, and I see this is still a topic of conversation. It's important to note (as you did) it is simply perception/variance, and people don't actually lose any income. If you can only find 1 share every 2 blocks, that share will pay enough that the income per block is still the correct average. This was a common point of confusion and misinformation a year ago. I suspect it will persist forever.

I don't know if you are running your own node or what, and this is my first time in ~8 months looking in the forum, but have you tried /DIFF if you want more frequent (but smaller value) shares? It won't do anything if you are already submitting at the network minimum diff level. But if you are on a public p2pool node that isn't running my old patches, your share difficulty might be higher than it needs to be. (I have no idea if any of my work ever made it into p2pool itself or not.)

Some info:

https://bitcointalk.org/index.php?topic=18313.msg6556442#msg6556442

I'd suggest running your own p2pool node is the best choice, secondly running off a public node running my patches unless someone else or forrest did something better which made them obsolete, or thirdly manually adjusting /DIFF.
