great, now just someone should make p2p exchange which is ddos safe and crypto is stabilized.
oh and it vould be a great idea to develop some wallet where you can have several crypto at once.

That will be done as soon as someone figures out how to P2P cash transactions. After two years, there's still no answer to that one.

Someone already made a p2pool for bytecoins, look at their source

Does anyone have upnp working with the window (either python or exe)? I swear I saw it work once but it's definitely not working now. I'm trying to figure out whether to blame my router or dig into the code a bit. I don't see any errors in the log file.

P2P between cryptocurrencies makes it at least possible to hold funds hostage for some time and in the worst case allows for double spend scams.
Between crypto + fiat (e.g. USD + BTC) you need external trust, either to an exchange or at least a gateway/bank that keeps fiat debt for you.

Multicoin wallet = ufasoft coin. It's at least useable, though not too pretty...

I'm still thinking that gift cards might work with this. Needs a bit of thought though.

I need some clarification on how the P2pool Difficulty operates with Litecoin.  I have a P2pool node setup, with my miners connected to it.  I've been mining the node for 1 month now, yet the difficulty/shares/payout still is a bit fuzzy.  I've appended my username with the /+ flags, and tried several difficulty levels.  I've seen examples of usrname/2000+16 or usrname/2+2.  I've made the assumption that the /2000 would be for bitcoin mining and the /2 would be for litecoin.  Can someone explain the difference between the /2000 & /2 and how it relates to Litecoin mining.

I understand the the /2000 is for the pool/share difficulty, and the +2 is for the miner difficulty.

Example Stats:
P2pool version:  11.3
Cgminer version: 3.1.0
P2pool share difficulty: 1.15 (according to the web/static detail)
P2pool share difficulty: 0.232827 (according to P2pool program feed)
P2pool requested difficulty: Difficulty 3.000  (my username/3+3)
P2pool Shares: 8 total (1 orphaned, 0 dead) Efficiency: 113.7%
Cgminer difficulty: 15.3K (according to cgminer)
Cgminer difficulty: 31.6M (according to cgminer)

I've received "accepted" shares in cgminer of 250k/15,300 with a difficulty of username/2+2; however, p2pool does not recognize or "accept" a high share like that.  I've also let the miners run for upwards of 48-72 hours and have odd payouts.  What's the voodoo magic behind p2pool & the difficulty settings?

Im trying to run a LTC p2pool node

It is running, I am able to connect with miners, but I am not able to access the web interfase.

I forwarded a local port 5555 to port 9338 on the node and i am entering http://localhost:5555/ in my local browser, but i am getting the following

r>)version�����q���yL��������������������������������������������������$zxRh9GC11.4���   9S>o.AYѪ r.\

Any ideas? The same thing is happening in 2 differente installations one running ubuntu 12.04 and one running ubuntu 10.04.

Thank you and best regards,

Any reason why you don't want to run it on the default port of 9327? I recently got mine up and running using the default port at http://mining.harvestcoin.com:9327

Could it be that your pointing to the wrong port?

why do you connect to the p2p port and not the web port? reading --help helps obviously!

You do realize localhost wouldn't use a port forward..

Cgminer version: 3.1.0
P2pool share difficulty: 1.15 (according to the web/static detail)
P2pool share difficulty: 0.232827 (according to P2pool program feed)
P2pool requested difficulty: Difficulty 3.000  (my username/3+3)

The difference between /2000 and /2 = bitcoin's algorithm is ~1000x "faster" at finding hashes than LTC's algorithm. Thus the difficulty must be ~1000 lower for the same amount of work.

Also, the /2+2 you are using means your p2pool server and stats are going to have a sparse sampling rate. I'd suggest something like /2+.002 (or .0002) otherwise your p2pool node will show extremely high variance statistics (unless you don't mind it and know your setup is ok).

Something else is suspicious with your setup, since you have so many different difficulties:

Could you post the line from the p2pool program feed that looks like:
New work for worker! Difficulty: 0.000200 Share difficulty: 0.994552 Total block value: 50.210500 LTC including 10 transactions

It should pretty much match the web interface:
Pool rate: 504MH/s (18% DOA+orphan) Share difficulty: 0.993

Notice both share difficulties are the same (+/- the delay it took me to hit refresh)

what version of p2pool are you using? recently they changed the way LTC share difficulty is reported to match what other pools are doing. What are the odd payouts you are getting? Your efficiency is > 100%, so it looks like something is working.

It's still the same as mentioned above:  "New work for worker! Difficulty: 0.232827 Share difficulty: 5.000000 Total block value: 53.123000 LTC including 45 transactions"  This is using: Usrnme/5+5

P2pool version is: 11.3 (I tried 11.4, that seemed to decrease my share rate further)  Cgminer version: 3.1.0.

I'm receiving payouts.  The odd behavior is receiving consistent share/payout per block of .45 LTC for 12+ hours, then it drops to .10 for another 12 + hours.  This happens when the p2pool node has been operating fine, along with all the miners connected.  Smooth & even hashrates.  The overall pool hashrate has a mean score of 580MH/s.  I would anticipate a much lower payout if the pool hashrate jumped to 1,200MH/s, but it stays within 100-150+- MH/s variance of the mean score.  My efficiency is normally between 110%-120%.

Thank you for the reply.

He wants you to paste that requested line, without using any /#+# switches, so the dynamic difficulty values are shown.

Also, +5 is way too high, as shown by the "Difficulty: 0.232827"... that value being used is the upper max p2pool will use based on the current dynamic share diff.

Using +0.0001 would be a better choice than using +5 ... maybe +0.0005 if you have a lot of hashpower behind it.

Your share diff for scrypt is too high too. Even setting it to /1 is probably too high for scrypt.
