Just started mining and have my two 5870's running at 900/600 with temps at 71. Not looking to push them too much.  Any reason you stopped at 600? My best hashrate is when the mem clocks are at 290 280. |

In the absence of user accounts where you can identify who really owns a miner address, you could do what eligius did for this same situation. They made users sign their request for namecoin <-> bitcoin address mapping with the private key for their bitcoin address.
You should do what eligius does. Bitcoin has signmessage and verifymessage for doing exactly this. |

How come your fee returned by " http://p2pmining.com:9332/fee" is 100%? Shouldn't that be 0.5 according to your statement? Or you just don't give rewards to those who connect to your pool?! I charge a small fee (0.5%) to use the pool since we don't get any of the transaction fees of the mined block.
JayCoin
he takes all of the payment and then splits it. He does payouts based on the 1 difficulty shares to help reduce variance for small miners. This wouldn't work well with generated transactions. If you don't trust him, just run your own bitcoind and p2pool node. |

I think there is still a problem with releasing RAM. I'm running Windows 7 Ultimate 64-bit. Armory worked great. I quit it, and my system shows the RAM usage drop to normal. However, I went to make a virtual machine with 4GB of RAM (My system has 6), and it kept crashing because it said the system did not have enough RAM. Then I tried to open a video game, and it crashed.
A reboot seems to have fixed it. Of course, a reboot seems to fix a lot of things in Windows, so it may have nothing to do with Armory ;p I'm pretty sure it is Armory's fault though. I'll test to see if I can reproduce it soon.

OMG thats such a relief from thats such a relief from that yellow desktop. Still having trouble with getting the miner started.
At first I was getting the "X server needs to be running" message and could not set clocks in aticonfig So I finally uninstalled and purged the xgldr drivers or some letters close to that, and then ran the AMD 12.1 w/ SDK 2.6.
So now I am able to get into aticonfig and play with those settings but whenever I attempt to run to run phoenix or poclbm I get this "Segmentation fault" line and then the attempt to start just quits.
Any tips from prior experiences would be greatly appreciated.

Try cgminer. It automatically sets the best defaults. |

I can't say I think this is a good thing, I'm from the UK and believe that a civilized society has no need for handguns, possession of an unlicensed firearm runs a 10 year prison sentence here.
However, if they're for sale on that site then I can't say I care that much, if technology allows people to risk imprisonment in a new and interesting way then they're free to do so.
Yeah. And the UK has no gun crime because of it... oh wait... it's gone UP since the ban. |

Does the P2Pool server behave like a regular instance of Bitcoind? I most definitely want to accommodate setups like this that I don't use, but a lot of other people do.
P2Pool just uses Bitcoin's RPC. It only deals with mining coins, nothing for wallets or any of that. It sounds like just allowing the bitcoin data directory to be passed as a flag or put in a settings file would be enough to get everything working in non-standard setups. |

In light of the recent hackings (I'm sure i've said this before  ) I just want to add some clarity on security. 1) My Wallet is not vulnerable to hackings in the same way that happened to bitcoinica and slush. If the server root was compromised the attackers would not be able to empty any wallets as they are only stored encrypted. 2) What the attacker may be able to do is change the javascript files to intercept password overtime and then decrypt the wallets. This would only effect people who logged in during this time, but is weak point none the less. I have made a small java app to help counter this: https://github.com/zootreeves/My-Wallet-Integrity-CheckerCompiling from source is recommended but you can download here: https://github.com/downloads/zootreeves/My-Wallet-Integrity-Checker/applet.jarWhen you enter your wallet identifier it will download your My Wallet page and check: a) The DOM for any inline javascript. b) For any unrecognised external javascript file c) Prompt for the user to review any inline javascript d) Verify all local javascript files match those at https://github.com/zootreeves/blockchain.info I have a cron job on my local machine to run this script regularly and alert me of any anomalies. also note: - It is recommended you enable double encryption which would keep your wallet safe if you only logged in to check your balance. - Enabling two factor authentication protects from keyloggers on your own PC (and/or use the onscreen virtual keyboard to type in your second password). - I receive SMS alerts on SSH login or when the tomcat context reloads (which is needed to alter any js). How did you setup your server to send a text when there is an SSH login? I'd like that for a couple of my servers. |

You CAN'T do this even if the computer is running nothing BUT bitcoin and malware:
Every program has a ram space, other programs can't touch it.
This means that even assuming data stayed alive in RAM a while (I never heard of such):
The virus would need to allocate almost ALL the computers RAM to itself in order to even get access the residue after the bitcoin client closed THEN it would have to search it.
This would slow the PC to a crawl and be VERY obvious.
This is incorrect. There are plenty of tools available for editing another programs RAM. This is how many of the public video game hacks work. |

Rig Box either way im gt spend 30k
Invest 30k into some companies on GLBSE and then once the rig box is closer, you can sell some shares and buy one. This way you can help out the economy while you wait. GLBSE? There are bitcoin companies you can invest 30K into? There are also Nigerian princesses you can invest 5k into Anyone that messes with BFL or GLBSE should be very careful, IMHO. You can get burned easily. How has either BFL or GLBSE burned people? BFL has been slow, but they haven't burned anyone. The only thing I've seen on GLBSE is the fake asset and you would have to have not read anything in order to put money there. If you have any meaningful amount of money, you should obviously be researching before investing. |

tl;dr: Have Python 2.6 and 2.7 installed, cant get 2.7 modules installed.
Why do you need Python 2.7? I'm running p2pool on 2 debian systems with Python 2.6 just fine. Theres a couple depreciation warnings, but those don't hurt anything. |

This client is beautiful. The descriptions for what everything is and how to do things are built right into the application. Best Desktop UI I think I've ever seen. Great work! I can't wait to setup my offline system!  |

Well reading this thread makes me realize we probably won't need vanity addresses or firstbits in the future. But they work for now. http://ecdsa.org/bitcoin-alias/Keeping aliases in the namecoin chain does sound a lot simpler and more functional since an alias can be much longer. |

Thanks. Dunno how I missed that. |

Well at least they didn't use my tax dollars for this.

Well the pirate box is going to need some sort of internet connection if you want to ensure no double spends and to allow any recent (since you last got the blockchain) coins/outputs to be spent..

Is any of this accessible from the command line?
I think this could be great for generating vanity addresses for other people.

Has anyone worked on getting secure zero-trust generation of vanity addresses by a third party? Something like the user generates a private key and a public key and then gives the public key to someone with a bunch of hashing power. They take the given public key and multiple it by a private key generated by vanitygen2.0. If that gives an address that matches the search pattern, the private key is sent securely back to the user. I think this could be a great service. I can't think of a way for the third party to prove they have generated the address without giving the key to the user. I was trying to figure out how to monetize this. EDIT: It looks like Armory has the math for this built in. (1)Emulated 2-of-2 multisig Note: this is only for the case that one party will be redeeming the full amount of the encumbered funds: there is no trust-free way to split the funds with this method (which makes it useful for Casascius+OtherParty physical bitcoins). - Each party produces a new address (which should not be in their wallet [explained later])
- From the wallet properties dialog, or the "Keys" tab in the calculator, fetch public keys and exchange with the other party.
- Fetch your own private key for the public key you just sent
- Use the middle entry in the calculator dialog, to multiply the other person's public key (enter x,y pair) by your private key
- Both parties get the same answer! This is because party A has private key a and public key a*G and party B has private key b and public key b*G. Both parties then end up producing a*b*G which is a new public key. However, neither party can calculate a*b (which is the private key for the public key both parties calculated).
- Calculate the address for the public key, and fund it with the amount of money agreed upon.
This is called an "Elliptic-Curve Diffie-Hellman" exchange (ECDH). It is usually for creating a shared secret with your public keys (such as an encryption key). In this case, it lets you produce an address that only someone with both private keys can access. At the end of this process, one person must send the other person their private key, so that they can calculate the shared private key and redeem the funds! This is why the private key you generate should not be part of any wallet, because it will eventually be shared and you never want to share a private key in one of your wallets! This could be used by Casascius and another party: Casascius and other party execute the process above, and fund the address with 1000 BTC (for a 1000 BTC gold bar). Casascius gets his hand on the gold bar, and puts his tamper-proof private key on it. He sends it to the other party, and they put their tamper-proof private key sticker on the other side. Now, the user with the gold bar is the only person that will ever see both private keys (once he peels them off) and thus, the only person that can ever spend them! Just plug one into the 'a' field of the calculator and the other one into the 'b' field of the calculator (if Casascius wanted to do this, I would add a simpler, reduced interface for multiplying private keys, but it is technically do-able as-is). EDIT: I am so rusty when it comes to C. I don't think this would be too complex to write, though. It would definitely slow down address generation since you have to do some key multiplication. A public key would be need to be passed as an additional argument. |
