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

[moharni]

Hi All,

I just joined the pool, however, I notice that there is something wrong just by looking at two miners one with 30 Th/s and the other almost 1 Th/s and in the past 12 hours, the first one (30Th/s) has 20 shares and the other one (1 Th/s) has also 20 shares  

I hope I am wrong but there is unfair advantage in which the second miner seems he can accumulate shares with very low hash rate then when a block found he unfairly receives a lot of bitcoins comparing to the first miner and to make things look fair in pool statistics, he increase his hashing rate to a very high number equivalent to his earning as soon as the a block found.  

First Miner: http://p2pool.org/stats/miner.php?id=1AYgpQEgKAeYBjYHa1ig9cmDNtztLrkNrV

Second Miner: http://p2pool.org/stats/miner.php?id=1KJxyw98ehK7ib3TrQ9afXSnS5YjNC9w9J

Can Anyone answer my question?

Thank you

Please let me know if you plan on running a BCH node with high uptime so I can add you to the DNS seeds list

Please add to BOOTSTRAP_ADDRS:

Share difficulty is adjusted based on hashrate. Also, the interface you're looking at will always display the most recent 20 shares no matter how many total there are.

Also, the node running at p2pool.org is overloaded and has poor performance (efficiency at 70%), so it is recommended that you run your own node or at least use a node with a faster CPU.

Yeah   When someone is investing couple of thousand dollars into mining they should afford average office PC with cheap quadcore, to set up Bitcoin Core + p2pool there. I wouldn't mine to remote node far away, there is too much losses on the wire, comparing what you can have if you mine to your local node.

Your rpc connection error seems very familiar to the LTC error I was having that this update corrected

I just looked again and still the second miner is performing better.

I use antminers S7 and the way I connect them to P2P pool is by writing the URL and my BTC address on it but I do not know how to run my own node or to know to which node I am connected to. Is there any tutorial how to do that?

Thanks

[bitlock1]

Post number 1 will get you started, and the  docs on p2pool github...... then there are over 800 pages of development...  P2Pool does take a little research to get up and running.... but I like the distributed network without throwing my hash power to Antpool.

Hi All,

I'm mining on p2pool\p2pool and p2pool\jtoomim (S3 miner set to load balance). The share dificulty of the pools are very different. On p2pool I have 34 shares in 3 days, but on jtoomim I dont have any shares over the last 3 days and my projected BTC is 0. The exspected time to share is only 8.6 hours.

I'm worried I've missed something. Is there anything I should check?

Thank you.

(My pool is getting close to being ready for testing. Just waiting on being assigned another static IP from my ISP. If your in or close to the UK and fancy giving it a go please let me know how you get on. www.mine4.com)

I'v also just finished a python script to trigger the donate to miners as detailed on https://en.bitcoin.it/wiki/P2Pool#Donating_to_P2Pool_miners

I don't have bitcoin to test this with but if anyone's willing to give it a go the details are below. The BTC addresses are assigned to different accounts and a cron job monitors their balance. When it is at or above 0.005 it will trigger the sendmany command and payout to 0.0001. Any remaining balance is allocated at random (see the wiki).

Donate to the pool

If you would like to support the miners currently active in either pool please send a BTC donation to one of the addresses below. Your donation will be distributed fairly amongst the miners within that pool, using the payment method detailed on the wiki.

P2Pool\Jtoomim - 1AZ5VJkgsTtvUMYQZ3JRGLRZ6VxqsrcPVw

I appreciate that this is a feature that may not be used all that much these days. I just thought this may make it more accessible for those who don't run a p2pool node.

James.

James , nice work! Glad to see more people getting involved in p2pool. Someone recently came up with a p2pool LTC node list/scanner. He is still working on it, but its impressive to me! http://mine.demon.nl/ltc-nodelist.html

If any one wants to join a discord channel that is pretty active and a majority of active users are p2pool miners / node operators, pm me and I will send you link. I've been in the mIRC #p2pool channel, seems dead personally.

Agreed, its intended as a backup pool or as a place to give p2pool a try, its primary purpose is the data it provides for the pool at large.

From the site:

Code:

By design P2Pool is intended to be run locally by the miner, and this is almost always the most efficient method.

It would be interesting to look at the logs. I assume that this is due to the increase in the size of the block

On p2pool I have 34 shares in 3 days, but on jtoomim I dont have any shares over the last 3 days and my projected BTC is 0. The exspected time to share is only 8.6 hours.

The initial share difficulty on p2pool/jtoomim is by default higher due to a bug I ran into with nodes with very high hashrate. If you have low hashrate (e.g. less than 3TH/s), it can be a good idea to manually set the difficulty by adding something like +512/65536 after your Bitcoin address in the stratum username field.

Hi,

Newbie questions

I'm on a jtoomimnet p2pool node with 32 TH/s. Node hash rate varies, but at the moment I'm contributing pretty much 60-90% of the hash on that node, depending on the time of day - it's pretty much me at this point, with someone else joining in and dropping out at times. The other person already has some shares, amounting to about 0.03 BTS, I have none. Node DOA is under 2% (currently 1.46), efficiency is 97.3%, share difficulty is 1520000. I'm new to p2pool and trying to understand the differences between a regular pool and p2pool. I did read up, but couldn't find answers to these questions:

1. "Expected time to share (this node)" shows around 3 minutes. I have been on the node for about 6 hours, and I have no shares yet. I thought that the concept was that at the hash rate the node is going, if I'm providing pretty much all the hash, the number of shares I receive should be close to what's predicted, i.e I should get a share every few minutes. What am I missing...?

2. I'm trying to understand the difference between a regular pool and p2pool. If I am hashing at p2pool but receive no shares (as is the situation currently) does that mean that the hash I contributed thus far will give me no payout whatsoever if at the time of a block being found I have no shares? So, is it more similar to a shared solo mining than a regular pool in that in a regular pool, any contribution will result in a payout when a block is found, even if ever so small, but in p2pool, if I have no shares, I may have contributed hash to the pool but no shares to me means I get nothing if a block is found by the pool?

3. If I drop off p2pool for a few days (while having no shares yet) and then go back, do I start over from scratch? Or the hashing I contributed earlier makes a difference?

4. One of the stats show this: "Total: 682 (Orphan: 41, Dead: 9)". Is this the number of shares to this node? Is it since the last block was found, i.e. it shows the current shares of this node towards the next block when it's found by the pool? It went from 660 to 682 since I have been on the node, and while I seem to be the biggest fish on the node since I joined in, I haven's received any of the 22 new shares created since I have been on. Again, what am I missing...? UPDATE: I have been the only one on the node for the last hour or so, contributing 100% of the hash. During this hour, the shares to the node went up by 3, but I still don’t have any. Confused... 

Sorry for the newbie questions - I did search first but I couldn't find direct answers to these questions.

[Kiefff]

Even after trying https://github.com/p2pool/p2pool/issues/241 , still cannot get p2pool LTC to accept +diff inputs from miners, ID+diff. It seems p2pool BTC side accepts +diff easily, but LTC side will not. Anyone else have any suggestions to correcting this?

[moharni]

Hi All,

Could anyone record a tutorial video showing how to setup mining with P2P pool as a local node. I think this will help also to attract more miners to the pool.

Thank you
Moharni

[jtoomim]

1. "Expected time to share (this node)" shows around 3 minutes. ... What am I missing...?

This metric is bugged. For example, my big node lists "Expected time to share: 1.2 seconds", which is impossible to sustain, as the protocol-level minimum share difficulty will adjust upward until the network as a whole creates one share every 30 seconds.

A difficulty of 1520000 should result in an average of 1 share every 1520000 *2**48/0xffff = 6.53 PH. With a hashrate of 20 TH/s, that should take on average 5.44 hours.

On my to-do list is changing a few things with the difficulty-setting and share-orphaning algorithms to improve both fairness and also to assign large miners higher-difficulty shares. This should substantially improve the number of shares small miners mine. It will not increase expected revenue for small miners, though; it will only reduce the variance.

The averaging period that determines your revenue per block is approximately 3 days long, so you are expected to have around 14 shares in the share chain at steady state, and so your variance will be around 1/sqrt(14)~=27%.

2. I'm trying to understand the difference between a regular pool and p2pool. If I am hashing at p2pool but receive no shares (as is the situation currently) does that mean that the hash I contributed thus far will give me no payout whatsoever if at the time of a block being found I have no shares?

Correct. On the other hand, if you find 2x as many shares as the expectation, then you get 2x the payout.

3. If I drop off p2pool for a few days (while having no shares yet) and then go back, do I start over from scratch?

Yes, after about 3 days you will be back to ground zero. However, if p2pool finds a block 1.5 days after you stop mining, then you will still get paid at about 50% of your normal payout level. Your expected payout ramps up slowly over 3 days, and it ramps down slowly over 3 days.

4. One of the stats show this: "Total: 682 (Orphan: 41, Dead: 9)". Is this the number of shares to this node? Is it since the last block was found, i.e. it shows the current shares of this node towards the next block when it's found by the pool?

Number of shares found on this node since it was (re)started.

UPDATE: I have been the only one on the node for the last hour or so, contributing 100% of the hash. During this hour, the shares to the node went up by 3, but I still don’t have any. Confused...  

That sounds weird. Perhaps you have your worker name/address set incorrectly? If that's the case, then you will end up mining to that node's default address, which usually belongs to the node operator. Your worker name needs to be a Bitcoin address starting with a 1 (no segwit or multisig addresses) and must not have an _ or ., though you may use + or / to set the pseudoshare or actual share difficulty.

I've also just finished a python script to trigger the donate to miners as detailed on https://en.bitcoin.it/wiki/P2Pool#Donating_to_P2Pool_miners

Given current fees on the Bitcoin network, in order for donations to be spendable, you need to give more than the fee it would cost to spend it. Currently, that's about 500 sat/byte * 200 bytes = 0.001 BTC per user, minimum. Given how many users there are and the hashrate distribution, a donation smaller than about 0.1 BTC would end up mostly wasted on fees.

Your phrasing is mostly identical to frodocooper's. You use this sentence

We need to spread more awareness on this issue to protect as many miners as possible using those Antminers.

Which is word-for-word identical to frodocooper's post. https://bitcointalk.org/index.php?topic=18313.msg18761195#msg18761195

You then went on to say

Anyone would like to chip in with their opinions about Antbleed here,please keep it civil as possible

Whereas frodocooper's post said

Also, to anyone who would like to chip in with their opinions about Antbleed here, please keep it civil and as apolitical as possible.

Frodocooper's account was 4 days old at the time he made that post. The jennaya account is 6 days old. The jennaya account also has recent posts offering "Social Media Campaigne ideas" from India and asking "Do you need best Internet marketing policy?"

What is going on here? Are you both reading from the same script? Is this two accounts belonging to the same person, who is copy-pasting this concern-troll message everywhere as part of a PR campaign? Or is there some other explanation for the similarity in these two sets of messages? Did jennaya just read through this thread's history and decide to plagiarize frodocooper's post as jennaya's own?

Curiouser and curiouser.
