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

[jtoomim]

looking at the nodes' scanner page, is there anything can tell us about CPU speed of a node?

Not really, no.

It could be "GBTL =Get Block Template Latency," but I do not know what dose it mean.  any idea?

GBTL is the amount of time that it takes for p2pool to get a response back from bitcoind when it asks for a new block template (i.e. a new batch of transactions). It is a poor indicator of CPU performance. It mostly just reflects block size. If the CPU is way too slow for p2pool, then this number will climb to 200 ms or longer (possibly even several seconds), but if the CPU is just a bit too slow, it won't show much at all.

But also, it is important to connect to a node that has small Latency (according to p2pool in this page: http://p2pool.org/learn/start.php)

That was written many years ago, back when block sizes were under 100 kB, long before p2pool started to show the CPU performance bottleneck.

that make sense, thanks jtoomim for the clarification

[moharni]

p2pool.org website is not showing full and updated information, for example, in the "miner dashboard" page, it shows only expected payout.

same thing for "P2Pool Node Data" , "Recent Blocks", "Active Miners (node)", and "Recent Shares (node)"

Anyone facing the same issue?

Personally, I tried the source versions from jtoomim and from Sawa.
Connecting the server to Internet through NAT or without it.
Bitcoin ABC version 0.16.1, 0.16.2 and 0.16.3

My node also does this and I would love a fix for it. It sometimes causes a lot a asic HW errors when this happens.  I'm using jtoomim 1mb_segwit  15.0-93-gb190c56-dirty
My guess is the miners are waiting for new work and stop hashing.

jtoomim, could you kindly create a new thread for your LTC and BCH P2Pool forks in Pools (Altcoins)? I'd like to keep the current P2Pool thread Bitcoin-only.

[notabeliever]

Yes  good idea as this move would give P2P more exposure

[sawa]

jtoomim, could you kindly create a new thread for your LTC and BCH P2Pool forks in Pools (Altcoins)? I'd like to keep the current P2Pool thread Bitcoin-only.

They are no different from the BTC fork. I see no reason to separate them.
Solutions found in the BCH and LTC forks will also help in the work of BTC p2pool

A very bad idea. The source code is the same. All changes apply to any coins.

Why write the same thing in two topics? The subject cannot be split.

I've seen this issue too, and have not yet been able to figure out the cause. I didn't realize it was affecting all nodes on the network at the same time. Thanks for pointing that out, it's useful information.

If you're running one of the nodes that does not have this issue (siberia.mine.nu:9338 and p2p-spb.xyz:9338) could you please contact me and let me know which version of bitcoind and which version of p2pool you're using?

These dips appears only if the rigs are connected to the nodes via the Internet.
If you connect the rig to the nodes in the local network they are not present.
In the screenshot #3 I marked it.

Hi,

I have installed jtoomim p2pool, rented a miner with 1.2Th/s on miningrigrental.
I am getting an error about very high difficulty from the web interface of the mningrigrental:

Code:

High Worker Difficulty
One or more workers on this rig has been assigned a share/worker difficulty by your pool that is too high. Hashrate performance issues may occur.
The OPTIMAL Difficulty range for this rig is 1,048 - 6,286
Please either adjust your worker settings at your pool, or change pools if you are unable to do this at your current pool. Thanks!

On my pool:

How does p2pool adjust the difficulty? What did I miss?
How can I lower the difficulty?
I have tried to pass "d=12000" as a password for the miner, but I do not think it made any difference.
Same miner works fine on p2pool.org:9332

What do I do wrong?

Thanks!

[jtoomim]

I have tried to pass "d=12000" as a password for the miner, but I do not think it made any difference.

The password is ignored. To set the difficulty to 12k, append "+12000" to your worker username.

From -ck's post about the rules of the Mining section:

2. This section is for BITCOIN MINING and related discussion ONLY. All bitcoin forks and alternate cryptocurrencies and discussion of them should be directed to a dedicated forum for those, or one of the altcoin subforums on this forum. All discussion regarding them will be moved without warning to the altcoin sections. If your topic is related to multiple currencies, then unless it is primarily about bitcoin it will be moved. Even if it is about sha256d mining but not about bitcoin it will be moved...

These are the rules of the forum. It's my job as a moderator to enforce them.

Any posts after this that are primarily altcoin-related will be deleted.

It would therefore be best to create that new thread in Pools (Altcoins) like I requested.

Thank you jtoomim for a difficulty hint, working through this.

[Q1] I will try other releases meantime. Lost in which one is THE one for jtoomim, can you help?

[jtoomim]

I will try other releases meantime. Lost in which one is THE one for jtoomim, can you help?

The current code is in the 1mb_segwit branch. I haven't been keeping the release tags up to date.

These are the rules of the forum. It's my job as a moderator to enforce them.

Any posts after this that are primarily altcoin-related will be deleted.

My reading of the rule is that this topic does not violate the rule. Take this sentence:

If your topic is related to multiple currencies, then unless it is primarily about bitcoin it will be moved.

This topic is about p2pool. P2pool is related to multiple currencies, but it is primarily about Bitcoin. As such, I do not think that this topic violates that rule. Note that the rule says "topic", not "post". My reading of the rule is that a post about an altcoin is permitted in this forum if it is relevant to the topic of the thread, and the topic is mostly about Bitcoin Mining.

P2pool has supported mining Litecoin as well as Bitcoin from the same codebase since 2012. Choosing to start forbidding altcoin posts after 6 years of allowing them is extremely disruptive. If you insist on forbidding them now, we will need to find another forum.

[moharni]

p2pool.org website is not showing full and updated information, for example, in the "miner dashboard" page, it shows only expected payout.

same thing for "P2Pool Node Data" , "Recent Blocks", "Active Miners (node)", and "Recent Shares (node)"

Anyone facing the same issue?

I’m on vacation (which is when things typically break), but everything looks ok from here, can you elaborate?

for example ,
1) the miner dashboard page shows only the expected payout for the corresponding BTC address without showing the hash rate graph or the recent shares.

2)  the node dashboard page dose not show my BTC address and others's in the active miner tab or in the recent share tab.

3) the recent blocks mined by the pool only show the ones that one year old or more

The active miner tab in P2Pool Global Dashboard page is working fine

Altcoin P2Pool has grown in significance and popularity relative to Bitcoin P2Pool over the past year, and it will continue to grow in significance as altcoins continue to grow in popularity, adoption, and market capitalization. Such significance, visibility, and popularity were not present before the cryptocurrency boom last year. Recent posts in this thread have hinted at this, as a growing proportion of these posts have been primarily about Litecoin and/or Bitcoin Cash, especially since after you released your jtoomimnet Litecoin and Bitcoin Cash P2Pool forks. So no, this topic has ceased to be mostly about Bitcoin mining.

Also, P2Pool did not support Bitcoin Cash until you released your BCH P2Pool fork.

It would therefore be more prudent and more beneficial to have discussions regarding altcoin P2Pool moved to the altcoin board, which is the proper place for such discussions and where such discussions are allowed to be more focused and more thorough. It would also allow this current thread to be more focused and more thorough when discussing the various aspects of Bitcoin P2Pool.

I understand that the underlying codebase may have far-reaching similarities between the different coins that P2Pool supports. In such cases where a post would cover both Bitcoin and altcoins, it would then be simply a case of posting in both threads, with links and/or quotes to/from each thread if necessary, and then distilling further discussions from that point on into their respective threads. It would be like how -ck deals with his ckpool.org and solo.ckpool.org threads.

Also, I'm not forbidding altcoin posts, but merely insisting on having them in the proper designated area.

especially since after you released your jtoomimnet Litecoin and Bitcoin Cash P2Pool forks.

Perhaps there is a misunderstanding here. I did not release "Litecoin and Bitcoin Cash P2pool forks". I only released one fork. That fork was created to allow p2pool to create blocks that were consistently 1 MB (or more) in size, as a fix to #341. The changes that I made early on in that fork broke p2pool's existing Litecoin compatibility. This prevented me from merging my code back into the p2pool/p2pool github master branch, which in turn forced my fork to remain a fork and forced the mainnet and jtoomimnet p2pool networks to remain separate. So bugs on altcoins affect the BTC pool.

Recently, I unbroke Litecoin compatibility in my code, and allowed people to mine with my code on the mainnet Litecoin p2pool. Unlike BTC, it's the same pool, same network, and 100% compatible with forrestv's legacy code branch. It just has better performance. Soon, once I work out the last few bugs and find the time to do some git wrangling, I will submit a pull request to p2pool/p2pool master which will unify the BTC p2pool networks and get everyone mining into the same BTC pool.

Support for mining Bitcoin Cash is new and unique to my code, but it is also not a fork. It's the same codebase as is used for the jtoomimnet BTC pool. Adding Bitcoin Cash support took 5 commits out of 1775 total commits. It was basically just adding config files for Bitcoin Cash.

Frodocooper, everyone in this thread except you agrees that splitting this into two separate threads -- one for Bitcoin, and one for everything else -- is unnecessary and would make it harder to participate in the p2pool community. Most of the people who have altcoin p2pool nodes also have a BTC p2pool node. Forcing us to use one thread if your node's port is 9327, 9348, or 7903 and a different thread if your node's port is 9332 is silly and arbitrary.

Altcoin P2Pool has grown in significance and popularity relative to Bitcoin P2Pool over the past year, and it will continue to grow in significance as altcoins continue to grow in popularity, adoption, and market capitalization. Such significance, visibility, and popularity were not present before the cryptocurrency boom last year.

This is the core of the issue. Bitcoin's market dominance used to be 95% or more. At that time, it might have made sense to segregate off non-Bitcoin discussions into their own sideshows. Now, Bitcoin's market dominance is only 35%, and so the distinction between Bitcoin and non-Bitcoin has become less important. Nowadays, Bitcoin is just one of many cryptocurrencies. As such, it no longer makes sense to give Bitcoin privileged status.

Splitting the discussion into Bitcoin and non-Bitcoin does not make sense. Moving the discussion entirely into the Altcoin forum doesn't make sense either, as Bitcoin is still the largest p2pool community.

This forum's structure was designed around a hierarchy that no longer exists. This forum topic should perhaps be in a forum titled "Cryptocurrency Mining" to encompass both Bitcoin and Altcoin. Unless you're planning on creating that forum, I suggest you just leave things as they are, since it seems to be working as it is.

Otherwise, we will need to move this discussion to another forum. I have created a thread on forum.bitcoin.com should that prove to be necessary:
