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.

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.

Awesome.  I'll find you on IRC sometime or send you a PM to discuss the details and to help get it up and running elsewhere.

Thank you for taking up the mantle, forrestv! p2pool.info is incredibly useful.

Speaking of VPS, does anyone have recommendations for running a p2pool node on a VPS? Any reliable hosts that are reasonably priced? I have no clue what I should be looking for in terms of minimum RAM and disk space and bandwidth.

I'm currently leaning towards myhosting.com since their plans are fully customizable.

At home, Bitcoin and friends are getting a dedicated machine due to expected disk I/O. While activity should drop once the chain is caught up, I doubt many VPS hosts will be happy with that type of usage.

I ended up going with myhosting.com with 100GB disk space, 4GB RAM, and 300GB monthly bandwidth (for now). The plan is easily expandable so I can always bump up the bandwidth, for instance. It's all on SSDs so disk I/O shouldn't be an issue. Syncing the blockhain overnight and then I'll try installing p2pool on it.

ovh.com has some machines in Canada that aren't sold out anymore.  The $29 one would be plenty..

or, you could try kimsufi.fr, ~$13 if you don't live in the EU.  Not sure if that processor could handle it, though

ed: https://www.datashack.net/dedicated/ is a budget provider in the US (missouri)

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).

Alright, the node seems to run fine on myhosting. Cheesy Now to run it overnight and watch for any hiccups.

300gb bandwidth is ... nothing

i hope it doesn't charge much for overage

I stopped mining awhile ago, but I've left my p2pool node up.  It's averaged 36 peers in the last year and it's bitcoind node is well connected.  It has a high speed internet connection and has had excellent uptime.

Is a node like mine actually helpful for p2pool?  I'm assuming that having a well connected node is good for spreading transactions and protecting p2pool from some kind of network attack.  Am I right, or is a non-mining node not helpful? It's just a git pull and a restart ever now and then, so it's not much effort.

If a non-mining node is helpful, is there anything else I can do to make it more useful?  Maybe set the max connections to something a lot higher so the pool sees more transactions?  I'm just guessing.

More importantly, your node will help with propagating blocks found by p2pool users. The more pervasive the p2pool network is, the fewer blocks are likely to get orphaned. forrestv apparently has something in the p2pool code that distributes the block super fast to prevent as many orphans, but I think that more nodes will also help to do the job too.

p2pool is unique in this respect, I don't think any other pool has a dedicated network of relay nodes running code to help propagate blocks, the centralised pools probably have to keep an eye on who their bitcoind nodes are connecting to and make sure they are using the most reliable nodes, the most well placed and those with the most capacious bandwidth.

Hi forrestv and all contributors of p2pool,

Many thanks to this fantastic mining pool. It's really fun to tuning p2pool to maximize miner's income for geeky users like me.

But I wonder if you have any plan to enable IPv6 support of p2pool?
Since official bitcoin client has IPv6 enabled by default, I think enabling IPv6 support will make p2pool network even more pervasive and well connected.
More importantly, IPv6 will help those users with both v4 & v6 network, but behind firewall or NAT in v4 network, just like me.
I do have a very good connectivity to v6 network and can accept income connections.
But v4 network is NATed with high latency, and I think that might be the source of my high orphan rate.

I have checked that twisted library used in p2pool support IPv6 network, at least partially.
I'm not familiar with python, so I don't know for sure.
I wonder if it is possible to enable IPv6 network in p2pool?

Thanks again to this great mining pool. :-)

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.

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.

The source code is now on GitHub:  https://github.com/ervwalter/p2pool.info

I'll work with forrestv to get it up and running on a new official server and then will transfer the domain name to him.  It's open source and so other are welcome to setup their own unofficial copies of the site, if they want to play with it for some reason.  Out of the box, the easiest (but not the cheapest) way to deploy it is on Windows Azure.  It's as simple as setting up a web server and a database server there and then pushing the code to the web server using git.  Setting it up on a non-Azure windows server is probably relatively straightforward as well (and may be much cheaper), but the specifics are left as an exercise for the reader.

Any way to convert the .bacpac to sql?

I'm all for IPv6, but will adding IPv6 support be enough for you?  I think you will still likely need to talk to IPv4 peers for a while since I doubt everyone in the pool can make the switch.

Not that I know of.  However, I re-exported the database as .sql files as well.  Note, these are still SQL Server specific.  Also, they are massive (as compared to the binary .bacpac file), so I moved all the data exports to its own repository:

It does not have to be all or nothing. You can run dual-stack as IPv4 addresses slowly become more and more scarce. APINC has run out years ago, so many of those new Chinese users are likely to be on IPv6.

Well... Adding v6 support doesn't mean disabling v4 network. We can have both networks up and running. p2pool will talk to both existing v4 peers and new v6 peers, just like the official bitcoin client does now.

And p2pool.info has been moved to forrestv's servers.  If you get any errors right now, they are probably related to us making DNS changes and the errors will go away over the next hour as your DNS cache expires.  If you still see errors after a few hours, let us know.
