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

[Krak]

ps: You have a data cap? ... Does the data cap only count on traffic that goes outside of our network? Do you get free in-network traffic?

AT&T has a cap on all of the data transferred on their network now; 150GB for DSL and 250GB for U-Verse.

We haven't received any kind of notice of such a cap, and with the speed plan we have here, I'd hit that 250GB very very quickly.

Maybe, tho, because you're more rural than I...

Nope, they didn't send out a notice (this is AT&T after all), but the caps are definitely there. They were added on May 2 last year.

Nah, they have to notify the customers of a change in the contract, which caps would be... otherwise, we'd be able to take them to court.

Even just having a note on one of the bills that they were going to change the terms, would suffice, but we got nothing.

Soo... we'll see...

My provider is Comcast, and I believe we only have a DL limit. When I looked at my account & bill settings online, it showed less than the 250GB limit for the past 3 months, and I'm only at 64gb this month. I don't think they UL is even measured for me.

I have been using p2pool to merged mine many chains at once for a long time now, it works fine for me personally however I am not at all sure how or where to find statistics about third party miners so that I can calculate appropriate payoffs for them.

Since the objective is to be able to give them choices about which type of coins they get paid in, I have commission set to 100% to prevent them getting automatic payments in bitcoins.

Looking through the browser interface I see some graphs but don't seem to be able find any clear summaries of how many shares or how much hashing or somesuch that each miner has contributed, nor any way to clear a miner's total on paying them in order to start accumulating a new work-total toward a future payment.

Functionality to do this is not built in.  You'll have to write custom code to do that yourself (as p2pmining.com did).

The Comcast/Xfinity limit has been suspended.

Under Users & Settings...

"Note: enforcement of the 250GB data consumption threshold is currently suspended."

I have been asked how p2pool knows how to pay third party miners who connect to it, and neither the wiki page nr the github page seems to say how that is done. I took a wild ass guess that its done by using a bitcoin address as username but is that correct?

Jaycoin said that he was open sourcing p2pmining's code. You can use it for your needs.

Yes.  When shares are submitted, they get credited to the address specified in the username (or to the default address if the username is not an address).

Yes, it was hacked and emptied. But it had the functionality that you need already working.

Check this thread.

[markm]

It seems even by the last page of the thread it was still not open sourced, at https://bitcointalk.org/index.php?topic=66202.460 you can see user shouting please open source it, but I dont see any affirmative response to that...

Is it crazy to see 6.3 gigs upload as a result of P2Pool traffic?  BTC and LTC?

Did you download the whole blockchain?

I've run p2pool for 10 machines on a cellphone ( during a fiber cut ) and only used 300 mb per day.

More likely it was people downloading the blockchain from your bitcoind, I've never noticed too much traffic using p2pool with around 40 connections.

The answer was in this very thread

I will release the code for p2pmining at the end of the month (as soon as I go down to Chicago to get my backup) if anyone wants to implement it. If someone wants to donate a server, I could set it up. If you just wanted to do bitcoin and namecoin merged mning, a VPS would work.

[markm]

Oh cool, thanks.

I am not really too thrilled by the idea of putting an additional front end in front of the p2pool though, and my aim is Massively Merged Mining, with a bunch of blockchains already waiting for enough hashing power to be available for them to come out into the public again...

EDIT: I am seeing now some console output looking like this

2012-08-23 12:51:08.201806 > Worker 1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx @ ##.##.##.## submitted share more than once!

Is this normal? (I see it more than once, presumably once per time they submitted the share, or maybe once per each tiem other than the first time that they submitted the share.) Or is it something they can correct at their end?

-MarkM-

EDIT-again: I also just got a couple of times another error I have never seen before:

I had done a git pull just a few hours ago, so I am restarting in case this error is due simply to the code having been changed while the pool was running. ( I have seen shell scripts lose their place in the script when the script was changed under them while running so figure maybe python might do that too...)

I know. The point of me saying that was to show I wasn't anywhere near "high" network utilization like the other member mentioned.

Merged mining in p2pool is not pooled.  If you want it to be pools (rewards distributed to multiple miners), you're going to have to invent that.  That is what p2pmining.com did.  You can use his code or invent your own, but there is no way to avoid having to add something on top of p2pool.

I am seeing now some console output looking like this
