[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[organofcorti]

I just posted a new analysis of p2Pool's statistics as per rav3n_pl's request: http://organofcorti.blogspot.com/2012/11/52-p2pool-achieving-expectations.html

I hope it dispels the "increasing the hashrate means the end of the world" myths, and I also hope one of you can answer a question I couldn't.

That's are my results, on Intel Atom 230 1.6GHz HT + 1 GB RAM:

It was after switching from bitcoind 0.7.1 to newest from git

2+ seconds, that sucks.

Look at it now! Newest p2pool, newest bitcoind compiled, same machine. It was 5s at the beginning, after customizations 2s, now it is 0.5s !

"There is no correlation between pool luck and pool hashrate, or orphaned block production and pool hashrate"
Eat this, infidels!

In some way I see pattern in "Shares per round / D as function of p2pool hashrate" graph, it looks like this:

It is a good thing rav3n_pl isn't prone to gloating...

Cmon Smoov, I`m just happy that math just proven my good thoughts about p2pool

sweet I found 2 blocks yesterday...

2012-11-20 18:22:08.027000 GOT BLOCK FROM MINER! Passing to bitcoind! http://blockexplorer.com/block/000000000000023638806d34a04439e98d8d3bcd23c6260e9708934dcbdbcfef

now we just have to get rid of v5 and v7 ppl

It looks like the LTC network switched over about 20min ago... showing no v8 and below in the desired version graph now. (not counting the mean indicators)

Yep, only pure red-ish v9 on LTC side

Hello,

Further to this post, where I show how you can use twidge and swatch to keep you informed via twitter about share and block events in the p2pool log, it occurred to me that if you are doing well at mining, the notifications can get a bit much.

Here is an alternative that gives you a daily direct message via twitter to tell you how many blocks and shares you created the previous day:

You need to install and setup twidge of course:

Code:

sudo apt-get install twidge
twidge setup

And then use

Code:

crontab -e

And add the following command:

Code:

5 0 * * * twidge dmsend paulkoan "$(cat /path/to/p2pool/log | grep $(date -d '1 day ago' +%Y-%m-%d) | grep -c SHARE) Shares, $(cat /path/to/p2pool/log | grep $(date -d '1 day ago' +%Y-%m-%d) | grep -c BLOCK) Blocks"

What this does runs a command 5 minutes after midnight, and scans the p2pool log for the previous day, getting a count of shares and blocks, then direct messages them to the userid in twitter:

Code:

24 Shares, 3 Blocks

You can modify the message of course, and change this to an update command instead if you prefer to public tweet your progress.  You can of course put the command in a script if you don't want this huge line in your crontab   You might want to modify to remove DOAs also.

woohoo, I got the last block!  cgminer reports best share is 14.9m. 

I'm curious why I didn't get a namecoin block too though.  I'm on merged mining, and I thought if you get a bitcoin block, you get a namecoin block.

Do a "namecoind listtransactions" command, see if the last one listed says 'generated'.

You won't see the generated coin as part of your balance until it has the usual 120 confirmations.

Yes all merged finds belong to yourself - there isn't a sharechain for each merged coin - they all go to the p2pool owner.

Ahhh.. right you are.  Didn't realize they don't show up like bitcoins do until 120 confirmations.  Thanks!

Too bad my 500000 iocoins and Ixcoins are worthless and the 10000 namecoins are a pittance.

Hmm, seems this doesn't work because p2pool cycles the log at a frequency greater than once a day.  Does anyone know how to lengthen the time p2pool keeps logs?

Hmm that's odd, my logs never cycle, but maybe that is windows thing.

It is not a Windows thing. It happens on Linux too @ 100 MB.

10000 namecoins is almost a block of bitcoins at current rates.  If that's a pittance for you, send them my way please.
