Nice to see a bit more hashrate in the pool

After reading ck and jonny explanation about difficulty scaling issue, isn't it the time to move to other pool ?

p2pool is a great concept but unless the dev come up with a solution for difficulty scaling. It can't go any further.
Maybe it couldn't be fix, who knows...

Interesting there are suddenly a bunch of noob accounts encouraging folks to jump ship...

The scaling issue is only an issue if p2pool has substantially more hash rate then it currently does.

The current problem is our hash rate is simply to low to find regular blocks, 1 decent sized miner can fix that.

There are plenty pools that could use your hash power:

Kano's pool
Bitminter
Johnnybravo's pool
BCMonster

P2Pool has a share life of either three days or three times the average work to find a block, whichever is lower.

Thanks, I was not familiar with the specific algorithm for share life.

Is it time to increase the Three day limit to Seven to be more realistic of current block time; and, if it is, is this something that can be changed slowly as part of a natural rollout or would it require a hard cutover ?

It seems to me that as the difficulty increases the overall p2pool hashrate decreases. Why is that?

Network difficulty increases as the network hashrate increases, so perhaps miners on p2pool are just keeping up with the rest of the network.

@organofcorti Ummm, I was asking for people's thoughts regarding why p2pool's hashrate is decreasing as the the network difficulty is increasing which is not the same as p2pool keeping up with the rest of the network. It is quite the opposite actually.

Less miners equals less hash rate. Down to 136 from over 250 only months ago. The culprit is the 3 day work drop-out. That period should be based on average days to block, IMO, although that might not be feasible.

@Songminer 3 day work drop-out?

Hi, i'm from venezuela and i have a large farm. But really i don't understand how can i mine with p2pool, i need to know if you can help me with my problem. I want mine with my own p2pool node but i need an interface for stats. I researched but do not quite understand how. someone you could guide me ?
Thanks

In p2pool it is biphasic. Initially as the hashrate of the pool increases your variation decreases, and then as the hashrate gets larger again, variation starts increasing again

Thanks ck (and Cortana)! I learned a new word today. Tongue

I've been reading about this p2pool difficulty scaling issue. It said the more hash power being put in, the more harder it gets and by the time it is high enough, it will be like solo mining.

This applies to any variant of mining, including a solo.

Nonsense. Pooled mining is nothing like that, except in the case of p2pool.

What nonsense? Difficulty is increased not by all miners, but only by those who added the extra power. With increasing difficulty of the coin in any type of the pool, those who did not extend their power will receive a smaller payment.
And this situation is both in p2pools and in the regular pools and in solo mode. If you want to get more benefits or to stay in the same level - increase the power of your equipment.

Your statements about rising difficulty decreasing your expected earnings are accurate. However, what you are missing is that because of the design of p2pool, the higher the hashrate of the pool, the more variance you as a miner will experience. This is completely the opposite of what happens in a more "traditional" pool.

The formula for finding a share on p2pool follows exactly the same probabilisitic distribution as solving a block of bitcoin. The simplified version of the formula is:

Code:

Difficulty * 2^32 / hashrate = time

As you can see, the higher the difficulty, the longer it's going to take you to find a share if your hash rate remains a constant. This translates directly into you as a miner seeing higher variance because it becomes harder and harder for you to find a share.

As Con correctly points out, if every single miner in the world suddenly started mining on p2pool then it would be very similar to each miner solo mining a coin roughly 1/20 the difficulty of Bitcoin.

ck, could you kind enough to explain to me about this scaling issue, preferably in noob wording lol...

In a regular pool, the more hashrate the pool has, the less variation there is in each miner's payouts. In p2pool it is biphasic. Initially as the hashrate of the pool increases your variation decreases, and then as the hashrate gets larger again, variation starts increasing again. If all miners were on p2pool, it'd be like they were solo mining at 1/20th of the current network diff which would be horrific variation. It's one of the limitations of the p2pool design that's been talked about, thrashed out and debated about for years on end without a solution.

Oh, how skillfully you mislead people. This statement is false, because those miners who did not increase their capacity with the increasing of the total power of the pool, will get fewer benefits in any system of charges.
At very high magnification power of a regular pool, there is a possibility that the weak miners (those who do not increase capacity) did not receive payments.
For example, if I will mine on your CKPool with the usual CPU this is the same thing as I tried solo mining.

Excuse me, but basically you seem to have no idea what you're talking about and it's hard to know if it's a language problem, ignorance or a combination of both. The solo pool I run is not regular pooled mining so it's pointless bringing that into the discussion. You asked for a simple explanation of why there's a scaling issue and I gave you the simplest possible explanation of what's wrong without describing at depth why. If you wish to understand further, please feel free to understand how pooled mining at other pools and p2pool work before arguing with me. I will not argue this further with you so feel free to have the final word which will make you feel like you've won the argument... until you educate yourself.
