Ah, thx.

Did anybody know, how can i setup p2pool to generate p2pool-share from all miners globally?
And pay them out over there shares on my node?

I know its not "hop-proof" but i have many small miners with usb sticks, and the p2pool-diff is too high for a single share from a miner.
So i mean many miners works on a node-share to p2pool network and become payouts based on miner shares to the node.

Or must i use eloipool ?

there is no built in functionality for that. You could set fee to 100% and then write your own script to parse http://yourserver.com:9332/web/log to find out what everyone's hashing power was per day and payout each daily based on that.

That is a good idea, but maybe outside of the scope of p2pool. A key property of p2pool is the trustless payout scheme. If you start centralizing payouts, then people start depending on a third party for payment.

A better way would be to lower the hashrate cap so large hashers don't flood the sharechain and push out small hashers. I think forrestv has done it, it's now:
https://github.com/forrestv/p2pool/commit/69d7300919e0f9b23ec81c1d01c0bf12cdb1ebc5
basically you get a max of 48 large-value shares per day so smaller miners can scrap up a few smaller value shares. At best it should lower difficulty for a share by 3 - might not be enough for usb sticks though.

Hy,

i have build it in my node last week...  i mine with 14 GBs, 45x 333 Mhz
I mine over 5 days and no p2pool-share was generated.  Unlucky? I dont think so.
I think, the USB Miner can not generate a share over 200K or over 100K in 10 sec or 20 sec.  And when, This is luck.
But so i can mine over weeks, month and become no shares, and when, so become only < 0.002 BTC...
But when i mine on a pool i become 0.01 per day, actually...

When forrestv add a modification in p2pool, i think a many small miners discover p2pool.
And when forrestv add a option for the miners, e.g. *address*/p0.02  for mining in node-share mode and payout 0.02 from node wallet-address. when it reached.

OR you write it, lower p2pool Diff. But this increase "dust"...

Wait, you got tired of people potentially donating to you (may not have been a mistake) and that's why you left P2Pool?  What if they were legitimately paying you a tip/donation with hash cycles?
If they wanted to donate, they could have just mined under a real mining address... it did have a 1% fee set

this is the monthly chart (missing the last two days since i've taken it down)

www.nogleg.com/temp/monthly_graph.html

and the weekly:

www.nogleg.com/temp/weekly_graph.html

i don't see that many workers on any other public nodes... that come in for a couple seconds then leave (even discounting 50% or more of the addresses being invalid)

my guess is my server is some fallback on some mining software somewhere?  either way, all those diff ppl ate up sockets that never closed.  i think it impacted 'real' miners when i set the max to 3 sockets per user

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

Hmm that doesn't sound right.  I have similar hash power (15Ghs) also using 45x Block Erupters and I have plenty of shares. As of this writing 14 accepted and 1 orphan for the same 7 days of runtime.  Check it out here: http://galactica.geekgalaxy.com:9332/static/

I just checked out your pool at http://smileandgo.de:9332/static/ and it looks like your 45 block Erupters aren't registering any hashrate at all on your pool node.  Are you sure you have your mining software pointing at your node correctly?  All I see is a few spikes here and there, but usually just 0 hashrate, so of course you won't get any shares.

OK, so I'm guessing people probably use 204.10.105.113:9332/static because of the domain p2pool.org... even though it's horribly set up & has a 2% fee.  quite sad really, when one looks at the one month/one year chart.  (oh and ofc he never took me up on my offer, no mails from that guy)

now, second question, why do people use elizium.name?... or is it just all local traffic?  though I'd be shocked if 95% or more of it wasn't just from random people using a remote p2pool.  400 shares I think is enough to get a trend & 55 orphans is bad.   I can see there's 11 outgoing connections, but I guess I'll assume that those are just random outgoing connections?   It looks like my node @ 198.12.127.2 used one of its random outgoing connections to hook up w/ it, but not connected to me at the other two places.   normally i'd add it to --p2pool-node since it seems to be on a fast enough computer & good connection, but i've just been observing the sub 100% efficiency for the last few days & curiosity killed the cat.  Is it all just because of that interface?  The most important part is busted (the share explorer).

I also don't understand why so many people use 183.136.216.39:9332/static/graphs.html?Year when it's absolutely horrid.  10 outgoing connections, that are either totally random or not good choices.  For location (China), he's not connecting to some critical western US & Russian nodes that he should be on.  I *think* it's also on an old version of bitcoind.  at least it's at 0% fee

But why would you use that over this:   mine.yuyi.tw:9332 a far superior pool in Taiwan with 1/10th the hashrate.  This one runs 0% fee too, so that's not it

is there some place i'm missing where these sites are being advertised?  reddit?  asic hardware manufacturer forums?  lol.    

some people want to use p2pool for whatever reason, but don't want to spend money on hosting for their own node (I'll assume they live in a crap rural area like myself w/ shit for bandwidth).   but why always choose the wrong pools?   then you get all the bullshit misinformation about how p2pool pays out less than <insert x pool>.  yeah, probably cause you were on one of these low efficiency pools or running a local node that was getting 15% orphans and 5% DOA..  though if it weren't for those people, I guess the rest wouldn't be picking up the bonus

but, seriously, who is mining on one of those 3 pools right now and why?   is there anyone that reads this thread that does?   if not, where are they coming from?

你懂中文吗?我不懂英文,183.136.216.39:9332是我建立的,但是我不懂编程这些技术,这是个普通的P2POOL节点矿池。我不知道如何去固定节点,或者应该怎么固定你说的美国俄罗斯节点。我只是和朋友在一起挖矿,可能是最差的池,来自一个完全不懂电脑程序的人,服务器是朋友提供的,没有打算收取任何费用。很高兴能引起你的关注,同时我也希望能得到技术上的帮助。如果你懂中文,是否可以用中文来帮助我解决这些问题,谢谢。钱包是的0.85版本。

I had to use google translate.   Grin  I'd say talk to this guy:  mine.yuyi.tw:9332        

https://twitter.com/TaiwanPool                                  (for one, you'd want him to --p2pool-node to your pool, since he has 0 incoming)

I've been saying for a while it's by far the best server in Oceania area....   it looks like he picked up a lot of hashing power recently and is still doing well on orphans

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher).

i have build it in my node last week...  i mine with 14 GBs, 45x 333 Mhz


*twitch*
GBs == Gigabytes per second?
Mhz == Millions of cycles per second.

While there is no SI unit for "hashes" as far as I know, 14Ghash/s and 333Mhash/s would be more correct IMO.

The Future of p2pool.info

As some of you know, I developed the p2pool.info website back when p2pool first started to take off because I was looking for a way to understand the blocks that p2pool finds, the pool's hashrate over time, etc.  This was at a time before p2pool has its own local web interface built in.

I no longer mine on p2pool info myself, but I've been happy to continue hosting p2pool info for the benefit of those that do because it currently runs on the same web server as one of my other non-bitcoin related project, and I'm already paying for those servers anyway.

Unfortunately, things have changed in the past few weeks.  My other web application has grown in popularity, and p2pool.info itself has doubled in popularity in the past two weeks (mostly with hundreds of new users out of China).  The result is that the p2pool.info activity no longer fits easily on the same server hardware as the other site. To keep my other web site up and running smoothly, I need to move p2pool to its own server, but that is not a cost I am willing to cover.

There are a couple options here.  

Option 1 is to just let p2pool.info fade away into history.  p2pool now has a decent web interface built in, and maybe that is good enough for everyone.

Option 2 is for someone else to take over ownership of p2pool.info (and assume all the costs).  The catch is that p2pool.info is not built with technologies that the typical bitcoin fan is probably used to (it's not linux/php/python/mysql/etc).  The application is an ASP.NET MVC application written in C# (and HTML/JS) and SQL Server as the backend database.  It's currently hosted in Windows Azure, but in theory could be hosted on any IIS/WIndows host without significant development changes.

What happens next is probably up to the community, and my short term plans are compatible with both options.

1. Sometime in the next few days I will make the code of p2pool.info open source and post it on GitHub.

2. I will also take create a data bump from the SQL Server database and make it also available on GitHub so that anyone that wants to host it can load all the existing historical data about p2pool.

3. I will take p2pool.info offline, or more probably will replace it with a static page that explains the situation.

I know p2pool.info is popular and is used by almost 1000 people per day.  Ideally, someone will want to take the code and host it elsewhere.  In fact, if someone wants to commit to doing that in the short term, I'd be happy to delay #3 for a bit to allow them time to get the replacement servers up and running.

Or if someone wants to read the code, understand what it's doing, and rewrite it in PHP/Phython/NodeJS/etc, I'm also cool with that.  I'm also willing to transfer the p2pool.info domain name to forrestv or anyone else established in the community that the community reaches consensus on so that the domain can continue to be used.

I'm sorry to be pulling the rug out with such short notice, but I have to do something along these lines to get my other web application working reliably as quickly as possible.

Really sorry to hear this. You have my thanks for running the service.

I use it often and can honestly say it helped me understand p2pool and stick with it.

I will be sending a small donation to the donation address on the website shortly.

I had to use google translate.   Grin  I'd say talk to this guy:  mine.yuyi.tw:9332        

https://twitter.com/TaiwanPool                                  (for one, you'd want him to --p2pool-node to your pool, since he has 0 incoming)

I've been saying for a while it's by far the best server in Oceania area....   it looks like he picked up a lot of hashing power recently and is still doing well on orphans

LOL,我看懂了,你和我一样需要谷歌翻译。好吧,你的意思是说 台湾 mine.yuyi.tw:9332池子效率很高。我昨天叫矿友们去测试了,效率是要好一些。我很羡慕你们懂的如何提升矿池效率,我不懂编程这些,能力非常有限,但是我尽量让矿池效率提升。我让矿友一部分算力进入mine.yuyi.tw:9332,分散一些算力,因为P2POOL节点矿池有个瓶颈,无论你的池子效率多高,都会遇见程序的瓶颈。

当算力大于3T,会出现吞噬小算力,如图



这个算力被吞噬了,完全失去了效率。

另外一个BUG,当算力大于3.5T或者4T以上,会出现算力溢出,如图




这些算力是溢出的,当4.5T可以看见有100G-300G算力被溢出。

如果你能联系上P2POOL程序的作者,应该让他优化程序,对P2POOL的发展是有帮助的。对大家都有好处,P2POOL算力值有50T - 70 T,目前的难度和矿机算力看,P2POOL需要尽快修改这些BGU。

如果能P2POOL使用stratum协议,效率会更高,为什么是目前的Getwork协议?效率很低!!!

请帮助我转达给P2POOL的作者,谢谢。我的英文不好,让他来看图吧。

另外你说的 https://twitter.com/TaiwanPool 添加为节点。IP = 59.24.3.173

请问bitcoin.conf该如何写呢?请帮助我,我真的不懂编程,这些命令我一点不懂。谢谢

rpcuser=abc
rpcpassword=123
server=1
rpcport=8332
port=8333
rpcconnect=127.0.0.1
addnode=59.24.3.173
addnode=

这样写正确吗???

可以给我一份这个bitcoin.conf的内容吗?请写上你认为更多的非常好的节点。谢谢!!!

如果你能帮助我,将会获得更多的算力加入P2POOL!

Wait, you got tired of people potentially donating to you (may not have been a mistake) and that's why you left P2Pool?  What if they were legitimately paying you a tip/donation with hash cycles?
If they wanted to donate, they could have just mined under a real mining address... it did have a 1% fee set

this is the monthly chart (missing the last two days since i've taken it down)

www.nogleg.com/temp/monthly_graph.html

and the weekly:

www.nogleg.com/temp/weekly_graph.html

i don't see that many workers on any other public nodes... that come in for a couple seconds then leave (even discounting 50% or more of the addresses being invalid)

my guess is my server is some fallback on some mining software somewhere?  either way, all those diff ppl ate up sockets that never closed.  i think it impacted 'real' miners when i set the max to 3 sockets per user


Seems like either they are using your pool as a testing pool or something (or otherwise probably a bot). You can probably change your p2pool mining port to a different one and see what happens.

I don't think zvs is going to be changing anything... he's dropped his P2Pool nodes (look at his posts before this one).

Of course, that doesn't mean he's gone... he still posts in this thread a ton more than most active P2Pool people.

Right zvs?  Wink

The Future of p2pool.info

As some of you know, I developed the p2pool.info website back when p2pool first started to take off because I was looking for a way to understand the blocks that p2pool finds, the pool's hashrate over time, etc.  This was at a time before p2pool has its own local web interface built in.

I no longer mine on p2pool info myself, but I've been happy to continue hosting p2pool info for the benefit of those that do because it currently runs on the same web server as one of my other non-bitcoin related project, and I'm already paying for those servers anyway.

Unfortunately, things have changed in the past few weeks.  My other web application has grown in popularity, and p2pool.info itself has doubled in popularity in the past two weeks (mostly with hundreds of new users out of China).  The result is that the p2pool.info activity no longer fits easily on the same server hardware as the other site. To keep my other web site up and running smoothly, I need to move p2pool to its own server, but that is not a cost I am willing to cover.

There are a couple options here.  

Option 1 is to just let p2pool.info fade away into history.  p2pool now has a decent web interface built in, and maybe that is good enough for everyone.

Option 2 is for someone else to take over ownership of p2pool.info (and assume all the costs).  The catch is that p2pool.info is not built with technologies that the typical bitcoin fan is probably used to (it's not linux/php/python/mysql/etc).  The application is an ASP.NET MVC application written in C# (and HTML/JS) and SQL Server as the backend database.  It's currently hosted in Windows Azure, but in theory could be hosted on any IIS/WIndows host without significant development changes.

What happens next is probably up to the community, and my short term plans are compatible with both options.

1. Sometime in the next few days I will make the code of p2pool.info open source and post it on GitHub.

2. I will also take create a data bump from the SQL Server database and make it also available on GitHub so that anyone that wants to host it can load all the existing historical data about p2pool.

3. I will take p2pool.info offline, or more probably will replace it with a static page that explains the situation.

I know p2pool.info is popular and is used by almost 1000 people per day.  Ideally, someone will want to take the code and host it elsewhere.  In fact, if someone wants to commit to doing that in the short term, I'd be happy to delay #3 for a bit to allow them time to get the replacement servers up and running.

Or if someone wants to read the code, understand what it's doing, and rewrite it in PHP/Phython/NodeJS/etc, I'm also cool with that.  I'm also willing to transfer the p2pool.info domain name to forrestv or anyone else established in the community that the community reaches consensus on so that the domain can continue to be used.

I'm sorry to be pulling the rug out with such short notice, but I have to do something along these lines to get my other web application working reliably as quickly as possible.


Seems like SQL Server eating up a lot of memory due to historical data?
That number of visitors should not be a problem for a medium sized server.

It's not the SQL Server that is the problem.  It's the web server.  The site does a lot of number crunching every time it calculates block durations, luck, etc.  That's CPU expensive, so it also caches essentially all of the results in memory (which include, among other things, hashrate data points for every 5 minutes for the past year+, so lots and lots of data in RAM on the web server).  I imagine there are other inefficiencies as well that are in the code, but I have not taken the time to investigate and track them down.  You're welcome to do so once the code is on GitHub.

It would fit fine on a server if it was by itself, but it's not.  It's on the same virtual machine as my other site with is much more popular and a more intensive web application.  There's just not room for the p2pool app on that VM anymore.  If the p2pool app used minimal resources, it would be fine, but it doesn't.

I see, will take a look once the code is on GitHub.

Is zvs the developer of the p2pool?

forrestv is.  

Ah, thx.

Did anybody know, how can i setup p2pool to generate p2pool-share from all miners globally?
And pay them out over there shares on my node?

I know its not "hop-proof" but i have many small miners with usb sticks, and the p2pool-diff is too high for a single share from a miner.
So i mean many miners works on a node-share to p2pool network and become payouts based on miner shares to the node.

Or must i use eloipool ?

Have a look at cryptominer.org - this is my node that is running a script that does something similar to that (miners are paid for their percentage of work done on my node). My modifications to the p2pool codebase are at https://github.com/forrestv/p2pool/pull/127

Thank you, twmz, for the long time you've spent supporting p2pool.info and P2Pool. Having p2pool.info around undoubtedly helped P2Pool become as popular as it is now.

P2Pool's built-in web interface definitely doesn't satisfy the same needs that p2pool.info does, and so I'd like to take on maintenance of p2pool.info. I'll bring up a suitable host and then I'd like to take ownership of the domain name and move it to that host for now, and then probably in the long term rewrite it to work on a Linux VPS.
