Anybody noticed that p2pool's hash rate has plummeted by about 30% in the last week ? Even more significant is the decline in the number of participants.

Beginning of the end of Bitcoin ?

Well, that sucks.

I just got my Jalapeno today. It's hooked up to BitMinter at the moment (I liked their fees and policies) but I had planned on figuring out how to use p2pool with it.

And really, I see little reason not to still do so, provided the collective hash rate doesn't drop too low. I'd probably be fine with one or two blocks a day. I know I won't be generating much soon anyway, but I'd still like to support the concept of p2pool for as long as possible.

So jalapeno p2pool yes or no?

No (see my guide for why).

And... that's even worse....

*looks for guide*

EDIT: OK, so the main problem with using BFL ASICs is the latency, which is made an issue by p2pool's 10-second share window. I don't know how popular the other ASICs are, but I would think p2pool needs as much hardware (especially powerful hardware) as it can get if it's going to remain a viable option. Has anyone brought up the idea of increasing the share window, even up to a full 1 minute? Wouldn't this effectively squash the hardware latency issue (and fix one or two other issues as well?)

The reason I asked the question above is because I'm working on a mining pool proxy for p2pool.  Basically, it records the shares you submit under your address, but it actually submits them to p2pool under the pools address.  When p2pool finds a block, I can make payouts based on shares submitted.  The aim is to help increase the total hashpower of p2pool by giving smaller miners the ability to contribute and receive reasonable variance.  I'm running some tests now, but hopefully I will open it up to a few testers within the next week.

Pooled proxies would allow p2pool to operate with larger difficulty shares and maintain low variance for end users.

Does anyone know why with Ufasoft CPU miner, I keep getting "Stratum authentication failed", but when I add --no-stratum it works?

Ohai.

haha, too funny!
1) dont CPU mine
2) there are faster CPU miners

another horrible miner
use cgminer or pooler's CPUminer

hmm this pooler's cpuminer better than minerd?

i have some xeons not doing anything, they get like 35mhash with minerd

oh, cool, looks like it was updated just a few hrs ago

hoho, that is minerd.  but i didnt know there was a new version  Grin

stratum wouldn't work for me either

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

Really strange but one of my friends who mines on my pool noticed he hasn't been getting any payout for his address on my LTC pool since Saturday. (he keeps a 200kh miner running most days at his work place that gets a small payout and adds his 7970 some days to boost the payout)

http://p2pool.dyndns.info:9327/static/graphs.html?Week

Graph for the week shows his payout just seem to have stopped on Friday after he turned off his 7970.

I've been running a miner non stop for the last few hours to check myself.

I've not changed anything, I've only restarted the LTC client and pool, connected a miner a few hours ago and still nothing.

Has anyone else ever had the same issues?

In your graph you have miners using Litecoin addresses to connect: their payout is not shown in the "Current payout to default address" which is perfectly normal.

Your friends should check the value for their address in the  "Payouts if a block were found NOW" section. On LTC payouts quickly drop to zero as the rate of blocks is quite fast and P2Pool looks for share produced approximately during the last 12 blocks.

Trade BTC for €/$ at bitcoin.de (referral), it's cheaper and faster (acts as escrow and lets the buyers do bank transfers).

They just open sourced the firmware. Implementing a custom nonce range might be what is needed to get BFL SCs to work with p2pool.

yeah i got .045 btc with just 575MH mining for less than 24 hours, feel so good

default settings are the best, 130 efficiency 0 orphaned and only 1% doa

This is so slow. With hashrate down payout increased by a percent but block find rate dropped by that same percentage... now the payout's very rough. It's either everything or nothing at all. It isn't smooth and steady at all. Now that the difficulty's shot up it takes 36 hours to find a block...

so you have 100 shares and 1 doa and 0 orphans?

at 575mh in less than 24hrs?

Solo mining is also isn't smooth and steady at all.
