Don`t panic! Organize!
We have new records there:
Pool rate: 546GH/s Share difficulty: 1230
I have not found any share last 24hrs :/ Payout drop to 0.000 Sad
Time for me to switch to LTC. I wish we have p2pminig back...

Sad  Have you tried manually adjusting your difficulty?

I don't understand what's happening either.  I'm less than 1% of the hash power, and I'm getting an average of .65 per payout, when it should be .5.  I'm running at 105% efficiency, because someone, or a bunch of someone is submitting a lot of stales, so that's part of it.  But I don't think it's all of it.

Feast or famine, and we're back to feast.  I guess it does scale.. including the famines.

I`m very small miner, may avg power is only 150MH. When it (share diff) was ~500 i found 5-8 shares/day. Now when it is over 1000 i found nothing. Mining LTC now.

Is this guy fucking serious?
I could ask you the same question. Why so superstitious?

Because of the past trends I have seen. IE: Days of green blocks on top of green blocks, and someone in the thread mentions how well we're doing, and "coincidentally"  the next block takes a day and a half. I suppose you could just chalk it up as variance. But it's also a bit like Santa, the Easter Bunny, or the Tooth fairy. If you believe in them, they "exist." Now I don't personally believe in those, but luck and karma are something I believe in. And from what I've seen, the block solving fairies don't like when we talk about their work.  Wink

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.

Jaycoin: Atm i've got a p2pool node running on my VPS (way overspec'd for the job anyways with 2GB ram, 2.5TB bandwidth and 4 cores at 3.2GHz(?)). Any specific OS you'd need to be able to set it up?

On a side note: WHO IN THE HELL MADE SO MANY FRIGGIN BLOCKS HAPPEN OVERNIGHT?!

Vote to change in code that will inerase share diff send to miner for big (>1GH) miners. This will not hur them and allow to smaller miners like me get some shares anyway. ATM we have 30 nodes less than 3 days ago. Small miners are running away.
1GH x2, 5GH x3 20GH and up x10 or something...

As I said above, I agree with the concept, but hardcoded hashrates is not a good idea. It does not scale, so I propose that we use default values depending on proportion ot total pool rate, and also keep the current way to set the difficulty manually.

can anybody explain the concept of this p2p pool in few words? is a from bitcoin seperated blockchain the fundation? thanks!

Of course there are many tutorials and the like, with many words.. I will try in few words:

- several hundred p2pool nodes, decentralized
- everyone solves shares
- shares, which solve the bitcoin blockchain difficulty, are broadcasted to bitcoin, receive the 50 BTC
- shares, which solve the p2pool sharechain difficulty, are broadcasted to p2pool
- the sharechain difficulty is adjusted so that there is a share every 10 sec (diff is between 500..1000)
- the node finding a bitcoin block includes payouts into the block for every other p2pool node, according to their share count (in the last 24h)

There are more details. When you want to switch to p2pool, maybe state your setup. We will hint you some details then (miner software, network connections, node hardware, custom difficulty..)

If you think that my entry in p2pool is breaking up things, I can move my miners to solo-mining. I'm talking of around 250GH/s.

I joined having in mind to help p2pool to perform better, not to upset people.

On the contrary!
There may or may not be scaling issues, it doesn't seem to be clear yet. However, I see it as a great chance to have you here, with a huge hashingrate concentrated in one node. If there are scalingissues. we already have them, and will have them even worse when, well, we scale up. We would need to fix it anyway. So lets better find out about it now, way before the BFL crazyness begins! :-)

A propos:
In theory, a much higher hashing power shouldn't change anything for p2pool. Lets say the difficulty rises a hundredfold, when the BFL come out. Then the block difficulty is a hundredfold, the p2pool hash rate is a hundredfold, and the share-diff will be a hundredfold too. The block time will adjust again to around 10 mins, the share time will adjust again to 10 secs. Even the network traffic won't change, as we will have a share every 10 secs just like now.

So, the big questions are: Do we have scaling issues? If so, why?
I only see scaling to influence anything in the short time when a huge node connects, dumps many shares, and the share difficulty didn't adjust yet. But this time window must be around a few minutes at most, not?

Tl:dr: pyramining, you are very welcome here! Even *more* if you are causing scaling issues! :-)

I agree with this. I'm not hurt that much myself but the small miners reallly are getting huge volatility. Most users (pyramining included) doesn't seem to bother/understand how to fix it manually so automatic is the way to go.

Agreed.

The + option (pseudoshare difficulty) is indeed disabled for the Bitcoin P2Pool due to me being paranoid, though that shouldn't be a large issue.

The other option (/) doesn't seem to be currently implemented anywhere (I PMd forrestv to find out about this)

The / option (share difficulty) is still there, though:

In work.py:
Code:
        desired_share_target = 2**256 - 1
        if '/' in user:
            user, min_diff_str = user.rsplit('/', 1)
            try:
                desired_share_target = bitcoin_data.difficulty_to_target(float(min_diff_str))
            except:
                pass
...
Code:
                desired_timestamp=int(time.time() - self.current_work.value['clock_offset']),
                desired_target=desired_share_target,
                ref_merkle_link=dict(branch=[], index=0),

I urge larger miners to use /3000 or higher in order to keep the variance down for smaller P2Pool miners. This will increase the difficulty of your shares to 3000, but each share is worth proportionally more. Simply append /3000 to the end of your miners' usernames. This will keep share difficulty (and consequentially, variance) low for small miners.

Also, don't worry, because no value is too high for either pseudoshare (+) or share (/) difficulty. P2Pool will ignore values of + that would cause it to drop shares otherwise, and the / value is capped at 10x the current minimum(default) share difficulty.
