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

[ovidus]

I have a programmer and 2 computer science / mathematics major interns going over the code this weekend should know more on Monday about the full scope of what needs to be fixed / implemented and a rough timeline hopefully, **fingers crossed**

Another thing I'd add to the list...

Fix being able to get lots of transactions without GetBlocktemplate Latency going through the roof.  OR something that alleviates the problem.  Long term p2pool isn't going to cut it if it can't get transactions.

M

Is that reliant on bitcoind only or also peers? I've been doing some tuning of bitcoind but struggle to keep it below 0.5 secs and not topping 1s.
Is that a bitcoind issue or a p2pool issue?

I thought anything more than 0.1 sec is too high?  If that's wrong I'll adjust my settings..

Don't forget we have this http://p2pminers.ideascale.com/ to help identify ideas and help collaborate. If we can identify issues and assign them to devs as well as using github, we can hopefully avoid duplication of effort.

Well my node seems fine with anything up to 1s. I only have 1 orphan out of 13. www.norgzpool.net.au

Any other node ops thoughts on this?

Anything we do will be on github as it integrates with our bug tracking software and also allows for transparency for the community so people can see we are not distributing malware and the such, and also allows for community contribution, we are also looking into making it easier to setup and run for multiple coins and a bit easier for people to add new coins when they release as well as possibly integrating an auto update function

Its not p2pool issue, use ssd disk and should be able to put
blockprioritysize=0
#blockminsize=2000
blockmaxsize=1000000
mintxfee=0.00001
minrelaytxfee=0.00001

With just 0.2s, with merged mining namecoin, fusioncoin, ixcoin and devcoin

i'm using fc disk and large caching. I've not seen blockprioritysize=0 before. that does that do?
also do you set maxconnections?

If i put maxconnections over 20 bitcoind starts to upload blocks with all upload bw, so I keep it 19
blockprioritysize=0 prevents 0 fee transactions

If Your home directory is on normal hd and system runs on ssd or theres mounted an ssd on /mnt/ put this on your /etc/fstab

/mnt/.bitcoin           /home/usrername/.bitcoin           none    bind    0 0

then as root cp -Rp /home/username/.bitcoin /mnt/.bitcoin

mount it

mount /home/username/.bitcoin

Then its on ssd

thanks, I've just set blockprioritysize and it looks like latency is down lower than its been. now around 0.2~0.3 but will monitor. ive got maxconns at 20. did you find that extra 1 really made a difference?
I have a 50mbit fibre link that achieves up to 70mbit up so I don't think i'll have any bandwidth issues with maxconns.

I can go with 40 (10mbit up) but hasnt found it useful, no deads with 19...

Ants seems to find shares just as easy with those settings mintxfee=0.00001 minrelaytxfee=0.00001 as 0.1 so it works here just fine with lots of transactions.. In fact when setting those to 0.1 to have blocktemplate to some ms, ants starts to submit share more than once..

Does anyone know where i can get the p2pool luck over ~ 1 year?

blockprioritysize=0 prevents 0 fee transactions

On my node, I set that to 196kB out of 500kB.

The fees are mainly to prevent spam, and are mainly a bonus at this point.

Between 12% hardware error rate, 20% penalty for no long polling, and another 10% for slow CPU lag (probably 3 seconds), I am getting 43% local DOA though.

Can Coin Cadence P2P Bitcoin Mining Pool frontend be dowloaded , it doesnt look so "beta" to me, I think it looks great and want to try it because it has many things in one place...

[HellDiverUK]

It's been a while since I played with p2pool. 

Can I have a full bitcoin node running, and use that same bitcoind to run p2pool?  I'm thinking not, due to the rpcpassword stuff, or is that separate?

This is getblocktemplate latency with 0.0001 fees...

.bitcoin .namecoin .devcoin .fusioncoin .ixcoin directorys are moved to a small 60gb ssd with nothing else there as mentioned earlier.

If blocks gets corrupted, its only umount /home/username/.coindir and restart client not the bootstrap project - if you have it there, then when its up to date shutdown client and cp -Rp /home/username/.coindir /mnt/.coindir remount it and restart client...

yes of course, running a second is impossible

What about chrooted bitcoind? Put it in jail perhaps
