So sorry, I think I understand a bit more now. So would you recommend that I use a client which does not compress their private keys so that I can move the BTCs around with worrying about compatibility issues?

oh...if that's the case, is there any way to export the "original" private key from Multibit? The one that starts with a 5?? So that I can restore my wallet to any client in the future without any worries?

I see..thank you for the reply!!

So I can use this "new" compressed private key on any client without any decompressing/converting to the old format or things like that?

I tried exporting the private key without password. I can see the strings in the .key file. However are these the "actual" private keys? If I'm not wrong private keys starts with "5"?? None of the strings inside my file is like that.

Glad to see that the pool is back. 

What is a acceptable % of stale shares for CPU mining? I average around 20% +- is this normal? I'm mining on several 32 core Xeon servers + cpuminer. Anything I can do to optimize their performance?

Yup..I'm pretty serious. And using CPU to mine LTC isn't as bad as you think. I can get 200KH per server(cpuminer) and I have a lot of servers in my data center. But they are behind a firewall which is causing me a lot of headache just to get them to connect to the stratum servers.

Guys I seem to be having some problem using CPUminer behind a firewall.

All my internet traffic needs to go through a proxy server. I have no problem mining BTC using any miner that lets me specific a proxy i.e cgminer...bfgminer.

I'm now try to mine LTC via scrypt + CPU + cpuminer. This is was I use.

minerd --url=stratum+tcp://global.wemineltc.com:3333 --proxy=http://proxy:8080 -u xxx -p xxx

Stratum connection failed: Failed connect to global.wemineltc.com:3333; No error

 

I'm also looking at going through stratum proxy but I don't think it supports a proxy server? Any help from you guys will be greatly appreciated!!

I too compiled a version of bfgminer which supports CPU mining. Trying to mine LTC via scrypt. This is the command I use.


This is the result I get. But don't seem to be hashing though. Am I missing something?

Guys.. I have been trying to compile bfgminer to enable CPU mining via scrypt on Windows 7.

I have been following the instructions in windows-build.txt I have reached the last step and just as I want to compile the miner I get this error. have been searching the internet for answers but couldn't find any. Any help will be greatly appreciated!!

What do you guys think would be a safe amount of overclocking for the BFs? Is over 3GH safe if I have enough cooling?

Cool!! If that's the case I will stop trying now. I was trying all sorts of combinations like adding sock4...and stuff like that. Looking forward to the next release!! Thank you and all the guys who tried to help!! 

I can do it with cgminer though and it's mining without any issues.

On the same machine and network, I can use CGMiner -> stratum.btcguild.com:3333 going through my proxy.

cgminer -o "http:proxy.com:8080|stratum.btcguild.com:3333" -u xxx -p 111

Is a certain amount of hardware error acceptable? What actually happens when there is a hardware error? I'm using CGminer 3.8.2 on a Win 7 PC. All miners are directly connected to a USB port not using a hub. This is what I'm getting, speed don't seem to be that great too.

oops. I made a mistake in my post. Yes, I was using stratum.btcguild.com:3333.

These are the commands that don't work.
bfgminer -o stratum.btcguild.com:3333 -x http://proxy.com:8080 -u xxx -p 111
bfgminer -o stratum+tcp://stratum.btcguild.com:3333 -x http://proxy.com:8080 -u xxx -p 111
bfgminer -o http://stratum.btcguild.com:3333 -x http://proxy.com:8080 -u xxx -p 111

These are the commands that work.
bfgminer -o http://api.bitcoin.cz:8332 -x http://proxy.com:8080 -u xxx -p 111
cgminer -o "http:proxy.com:8080|stratum.btcguild.com:3333" -u xxx -p 111

At least I know that I can do it behind my firewall, it's just that I don't now the correct command or bfgminer does not allow connection to stratum via proxy?

Hello guys!!

I seem to be having problems connecting to a stratum server via a proxy server.

I'm mining behind a firewall and all my internet connections have to go through a proxy. I can use cgminer and stratum.btcguild.com:3333 via proxy without any problem. However I would like to use bfgminer instead as I have been hearing many good things about it.

I have tried all sorts of commands, however none of them seem to connect

bfgminer -o stratum.bitcoin.cz:3333 -x http://proxy.com:8080 -u xxx -p 111

bfgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -x http://proxy.com:8080 -u xxx -p 111

bfgminer -o http://stratum.bitcoin.cz:3333 -x http://proxy.com:8080 -u xxx -p 111

This however would get me connected.

bfgminer -o http://api.bitcoin.cz:8332 -x http://proxy.com:8080 -u xxx -p 111

I'm mining at BTCguild, and you can only connect to them via stratum??

Any help will be greatly appreciated!! Thanks a lot!!

Current Energy Efficiency Statistics:

As of November 12, 2013
Market Cap: (Bitinfocharts)
Bitcoin    11,984,125 BTC
Peercoin        37,439 BTC

Hash Rate:
Bitcoin 5.1Q
Peercoin 12.25T

Value secured by a Giga Hash
 Bitcoin:     11,984,125 / 5,100,000 =   2.35  bitcoins secured per GH
 Peercoin:       37,439 /       12,250 = 3.06    bitcoins worth of Peercoins secured per GH

Calculation:
(3.06 - 2.35) / 2.35 = .302 (or 30.2%)

Conclusion:
Peercoin is currently 30.2% more energy efficient than Bitcoin. I would think that this energy efficiency should increase over time as well.

I was at 1 of the PPC forums and it seems that after some calculation, you can get more BTC via mining for PPC first. What do you guys think?

Do you guys support cgminer or bfgminer??
