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

[BTCNU]

Thanks. Based on that, it sounds like maybe I don't need to be running a P2Pool. Doesn't benefit anybody much and it's just causing me heart-ache. :-)

I will continue running the bitcoind node, however.

1: How can I tell if people are using my P2Pool node?
2: If I don't mine, is there any reason to host a P2Pool node?
3: My GetBlockTemplate latency is rarely/barely under 1 sec, even with just P2Pool and Bitcoind running. Why? CPU usage is almost nothing, disks are SSDs and there appears to be no swapping happening.
4: How do people find a P2Pool node to use, and what kinds of things helps them make the decision about which is best for them?
5: Is the P2Pool network hurting for nodes, or is there a surplus of nodes and it's just miners that are missing?

4) orphan rate and whether DOA is excessive vis-a-vis probable latencies.  i used to mine at 200ms pool.  with 15s share times, i'd get around 2.5-3% DOA

example: p2pool.org latency isn't that bad, yet DOA far exceeds mathematical probability

Mine are much lower now too out of 60 shares I have 4 orphan and 4 dead. It use to be a higher.

Both of these make P2Pool easier to use; the eventual goal is being able to run P2Pool on the same hardware miners use, such as a Raspberry Pi, though that would likely require a laborious rewrite in C++ or another compiled language.

My current progress on this: I have a piece of software talking to bitcoind and augmenting blocks with UTXO merkle branches, feeding that to another piece of lightweight software that can trustlessly verify the blockchain, while holding O(1) state. I have a good idea about how the non-linear sharechain will work, but implementing that hasn't started yet.

• Why a UTXO proof vs. a TXO proof?
• How do you see these p2pool nodes starting up? Will they get the UTXO set from another node, or verify some or all of the blockchain themselves?
• Have you thought about what happens during a 51% attack? What if p2pool has a larger share of hashing power than it does now?

How do I configure this stupid bitcoin-qt app on my P2Pool?

I am trying to transfer out 0.26017615 BTC and I told "the total exceeds your balance when the 0.001 BTC transaction fee is included". So subtract the 0.001 fee and put in 0.25917615 and it now tells me "the total exceeds your balance when the 0.002 BTC transaction fee is included". WTF really? Why can't this f'n application work?

Plz help, thanks!

A little off-topic isn't it?  Bitcoin-Qt may be used by P2Pool (or bitcoind instead of Bitcoin-Qt) but this isn't a P2pool question.  Sort of like asking why Python didn't install in this thread.  Nothing to do with P2Pool.

That said, try checking your Preferences in Bitcoin-Qt. The Main tab has the default transaction fee setting.

Looks like we lost multipool to eligius recently, which is a big chunk of TH (currently 12 TH, but I think sometimes 20 TH or more).

However, I'm not seeing a drop off in total hash rate, so I guess there is enough coming online to take its place. Nasty just added 1.6 TH and I added almost 1 TH.

I hope we can keep p2pool viable.

reported speed is 98 TH right now, speed on p2pool.info still shows 150 TH but is clearly wrong.

BTW, those 1TH units popping up like mushrooms after a rainfall seem to behave fairly well on p2pool, I'm testing one since yesterday.

What is the default transaction fee supposed to be set at?

I remember gmaxwell reporting the Cointerra machines work wonderfully with p2pool. Wish more CT owners would install some nodes and get with the p2pool program.

I've heard they work very well even with a remote node. Obviously separate nodes are better for decentralization but for p2pool to survive it needs to grow hash rate here, so even getting people on remote nodes can be a means to an end.

They do work quite nicely with p2pool.com  ;-)

I've been making some scrypt-based altcoin p2pools and I've noticed that for the first 30 seconds or so of mining in a new p2pool instance, the vast majority of work results in hardware errors. I've tried letting the p2pool run for a while first to make sure everything is fully "loaded", but this doesn't seem to make a difference. Several users, including myself have verified this, and it's not a mining hardware problem. I never, ever get a HW error in any other circumstance.
Has anyone else experienced this and/or know of a possible solution?

Yes I submitted a patch to fix that.

Ok, thanks

[bkminer]

Does anyone know of HashFast works well on p2pool (doubtful I'll ever get it but just in-case)....

Also I've noticed that we've dropped from 1% to 0.35% in a little over a month... network is really growing now...

how to use p2pool for antminer S1 ?

how to use p2pool for antminer S1 ?

Easy. Set miner url to the IP of the p2pool node followed by 9332 (example: 1.2.3.4:9332) and set your username to your bitcoin address.
