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

[Rubberduckie]

So I'm still mining ok? (I upgraded to latest p2pool)

Yes. I'll push some changes soon that drop unupgraded peers instead of throwing up so many errors.

[Rubberduckie]

Sounds good P2pool is awesome

I have two CLC connections too, and presumably luke-jr is no longer merged mining it with Eligius miners' hashing power as I have also got some confirmed blocks. Hmm or he is and I too am on a fork?

Maybe you are one of my two connections and I am one of your two? 142.177.234.* is one of the class C networks my ISP assigns me an IP on, and is the one I am on right now. Got a connection from that net?

Nope, you're not...

Should we try to merge ourselves back together or is that even possible not knowing how long we've been seperated?

I am pretty sure the MiniUPNP lib does not work with my router, so I probably do not have incoming ports. However if you don't have IRC turned off presumably my client should see yours in the IRC channel and call out to it.

Maybe though they forgot to limit the number of IRC channels, leaving a vanishingly small chance that any two clients happen to randomly choose the same channel, or maybe some versions use one IRC network and others another.

...There are five channels, 00 through 04, so only a one in five chance we land in the same IRC channel.

There probably should be a commandline and/or config setting to fixate on a specific channel but I do not think there is.

Maybe also it should check the channel actually has clients in it and if not try another.

Maybe whoever runs the main nodes the fallback methods use has shut down or something, I wonder if they have a DNS thing set up for finding fallback nodes, or a list or something?

If you have an incoming port, I can tell mine specifically on the commandline to connect to yours, most of my shell scripts for startign coin daemons have a few nodes hardcoded into them.

While we're at it, if you can open incoming ports, maybe you could run GRouPcoin too, the people who had that runnign in EC2 instances to be used in such hardcoding in scripts seem to have shut down their GRouPcoin daemons...

Both DeVCoin and GRouPcoin could also do with having the DNS system set up, problem with both is I haven't yet any list of reliable nodes to actually plug into DNS for them...

My client is going to IRC and I do have a port open for incoming connections.

If you want to give it a try, connect to the ip of blockexplorer.funkymonkey.org port 8368.  (addnode=ip:port in your coiledcoin.conf file)

I've got a GroupCoin client running but no one to connect to so it's sitting at block 0.

.. we should probably start a separate thread for this so we don't derail this one and so others can see if interested...


edit:  I joined all 5 irc channels with my desktop client, the first channel 00 is the only one with users and you're one of them... not sure why you're not trying to connect..

edit 2:  I can open ports for groupcoin however, I wouldn't hard code my IP into anything.. Everything I have runs off a residential internet connection.  My IP hasn't changed in a couple of years but it does change from time to time and there's no guaranteed uptime here from my provider.

That's a transaction, not a block; and no, the associated block wasn't orphaned. If you weren't paid, you either didn't submit a share the previous 24h or mined on a different p2pool fork.

P2Pool release 0.9.1 - tag: 0.9.1 - UPGRADE TO >=0.9 REQUIRED before Mar 4, upgrade to 0.9.1 will make transition go more smoothly

Windows py2exe binary: http://u.forre.st/u/jkwntafq/p2pool_win32_1cf73bc.zip
Source tarball: https://github.com/forrestv/p2pool/tarball/0.9.1
Source zip: https://github.com/forrestv/p2pool/zipball/0.9.1

Changes:
* Some fixes to make the transition on March 4th go better
** P2Pool will switch using the sharechain's time instead of your local clock's time, so people with very incorrect clocks won't be hurt
** P2Pool will disconnect from and ban unupgraded peers so you won't be spammed with error messages from the few people running older versions


Persistent note: I would recommend switching to Bitcoin 0.6.0 RC 1, which includes the RPC getblock call. The getblock call lets P2Pool keep track of block heights more robustly, and so might protect you from sharechain forks. Download it from https://bitcointalk.org/index.php?topic=63165.0

Thanks for all your hard work at keeping Bitcoin decentralized and secure forrestv.

Rebooted PC and the payment showed up in the client.

Is it possible to turn off dynamic share difficulty for local shares?

New work for workers! Difficulty: 9.8273 Share Difficulty 635.184144

I don't really see the point of this.  Even at 10GH/s locally the amount of miner traffic is minimal and it is on the LAN.  Keeping shares difficult 1 locally allows apples to apples comparison at the miner level.

With dynamic difficulty changing I just realized it made comparing stats (in cgminer) between rigs with different uptimes impossible.  cgminer reports total # of shares but those shares represent different amounts of work.    I was comparing mem clock difference between two rigs and the stats are junk.  Stupid me for not thinking of this before running the trial.

Is there a command line argument to specify a static local share value?  If not can it be included in the next version?

If you comment out line 533-538 in the main.py file (newest version) it will serve only diffficulty 1 shares to your miner

See before and after below.

Before:

Code:

                target = net.PARENT.SANE_MAX_TARGET
                if len(self.recent_shares_ts_work) == 50:
                    hash_rate = sum(work for ts, work in self.recent_shares_ts_work)//(self.recent_shares_ts_work[-1][0] - self.recent_shares_ts_work[0][0])
                    target = min(target, 2**256//(hash_rate))
                target = max(target, share_info['bits'].target)
                for aux_work in current_work.value['mm_chains'].itervalues():
                    target = max(target, aux_work['target'])

After:

Code:

                target = net.PARENT.SANE_MAX_TARGET
                # if len(self.recent_shares_ts_work) == 50:
                #  hash_rate = sum(work for ts, work in self.recent_shares_ts_work)//(self.recent_shares_ts_work[-1][0] - self.recent_shares_ts_work[0][0])
                #  target = min(target, 2**256//(hash_rate))
                #  target = max(target, share_info['bits'].target)
                #for aux_work in current_work.value['mm_chains'].itervalues():
                #    target = max(target, aux_work['target'])

Thanks I may have to do that.  My p2pool rig is my windows workstation so I use windows binary version temporarily I could use python version but really I think this should be a user defined option.

So between running Bitcoind + p2pool and whatever else is needed, what's the footprint in terms of processor/memory/disk space?

On my system

Memory:
bitcoind uses about 120MB, p2pool uses about 70MB.

CPU:
CPU time is essentially 0% (except when downloading new chain until caught up).

Disk:
bitcoind ~1.3GB  p2pool ~<100MB (truncating log would make it <30MB).

Probably not going to run very well on my router

My pool works a little different from a public p2pool server.  My pool tracks the difficulty 1 shares submitted and then distributes the p2pool reward proportionally.  This is so your miner doesn't actually need to get a block on the p2pool share chain to get the reward (Great for low hashrate miners).  Current fee is 0.5% with auto payouts after a balance greater than 0.5 BTC.  See the thread https://bitcointalk.org/index.php?topic=66202.0

Ah, ok.
