But guess what, Solidcoin is based almost completely on the Bitcoin code, which means it is also vulnerable to the very same attacks that SolidCoin is feverishly trying to protect itself against.
I stopped reading when I read that because that's not even close to true. CH screwed up the Bitcoin code, which made it vulnerable to attacks that Bitcoin *does not* suffer from. He screwed it up because he was tinkering with code he does not understand. |

The gg client itself seems to be working well enough. Wish I saw more connections though, I'm usually seeing them in the low 20's. I think the highest I've seen is 29. With the .24 bitcoind I normally see over 100. Running Ubuntu 10.10 x64 on a single core AMD.
There just aren't that many gg nodes running. As soon as an exchange goes up then I'm sure you'll start seeing a lot more connections. |

Just a little bit of background on us. We are seasoned designers with long job histories with companies like IBM, Altera and others.
No, you're some anonymous person posting on an Internet forum. You have zero credibility. |

Your setup computes 1.71 Mhash/Joule. Although there is a lot of invalid data in https://en.bitcoin.it/wiki/Mining_hardware_comparison your claim is inconsistent with the wiki which puts the value anywhere between 1.3 and 1.6 Mhash/Joule. How did you measure 650W? Do you under/overclock the GPU or memory? Etc. You mentioned 5830s so I picked that rigs as an example. 1.71 isn't even my most effecient rig. You have a farm. Are you saying you can't pull off 1.71 Mhash/Joule on any of your systems? Who cares what the wiki says. The wiki is old and outdated. 1. Buy quality parts. 60% efficient power supplies are stupid. 2. Plug system into Killawatt meter. 3. Use latest mining software and optimize hashing parameters. 4. Overclock core speed and underclock memory speed. 5. Keep fans clean so nothing overheats. There's no rocket science here. Just basic mining optimizations that any half-decent miner would do. |

I am also going to invalidate the 1000 inserted blocks. The bounty coins will remain.
Where are those 1000 blocks? |

Where do you live, Hawaii? Break-even is around $.20/kwh on a decent rig. The days of running a farm with electricity rates that high are over. Liquidate your hardware now.
Tawsix said below he pays $.15/kWh during the day and $.08/kWh during the night. My guess is that he made the mistake of building a farm mostly from 5830s which have terrible power efficiency. At $.15/kWh his cost of production on a 5830 is about $5.9/BTC, clearly losing money when the exchange rate is $4.8/BTC. My 4x5830 rig draws 650 watts and outputs 1112 mhps which generates .64 btc and draws 15.6 kwh. .15 for 9 hours and .08 for 15 hours is about .11 per kwh average per day. Cost to generate btc is $2.59 per coin. Sounds like his efficiency is half of what it should be. |

I don't see the point of continuing SC when GG is up and running. Faster blocks, faster difficulty adjustments, faster implementation of bug fixes, etc.

I think the biggest problem will be people with 8 connections. Meaning, they don't have ports open, so are really quite poorly connected to the network. These people will get orphaned more often than everyone else. Make your blocks count. Open incoming connections.

I've been mining with 6 ghash and just now I saw that I found 5 blocks in a row. Immediately, I realized something is not right. I can't be that lucky. After a few minutes, I saw that these 5 blocks all got orphaned. I assumed that due to network issues, I was disconnected enough to build up my own block chain, which got wiped out when I reconnected.
Unfortunately, I think these problems will get worse as the network grows.
Interesting. I wonder how things will play out as we start hitting 100, 200, 300 GH. Won't matter if we have 100 TH. After a few quick blocks, difficulty will adjust, and we'll be right back to 15 second blocks. |

I apologize for the delay, but the truth of the matter is that at current prices of BTC, we will have operated in the past week at a slight deficit. I am waiting for BTC to go back up in price to at least cover the cost of operation. I do round up when I calculate energy costs, so we won't be going into the negative financially. I have confidence that Bitcoins will rebound from this slump. I will update further once the situation is resolved.

Um, I am no actuarian coblee, but it seems to me that the original bitcoin paper does not state that probability of attacker success is a function of time.
The paper is considering the probility of successfully completing a single attack. Roughly: 6 bitcoin confirmations = 60 minutes 6 gg confirmations = 1.5 minutes On the gg chain, you can perform 40 times as many attempted attacks in the same time period. So even if the odds for a single attack are the same, you get 40 times as many attempts, so clearly time does effect the security. |

56*60= 3360 minutes 3360 minutes * 60 = 201600 seconds 201600 seconds / 13191 blocks = 15,2 seconds per block. We're on schedule, lol  Ok, that looks much better. That's very good it's sticking so close to projections. |

56 hrs ago? 13200 blocks in 56 hours is nearly a block every 6 seconds. I thought this was still targetting 15 second blocks. |

I'm impressed. I thought with such fast blocks there would be more orphans. I'm seeing only 2%. The frequent difficulty adjustments are also great. Miners come and leave and the difficulty adjusts real fast. Someone's got to do a block explorer so we can see how the blocks are coming. We're at 13000 blocks. Exactly when was this chain started?

This alt didn't even change the name of anything from bitcoin? Even the addresses are still bitcoin addresses? Redo!

Independant? What makes you think the hash-rate increases/decreases based on whether the person sitting in front of the computer is biased or not?
Because the hash-rate is dependent on many variables including OS, SDK version, Driver version, and numerous miner versions and settings. I get about 2% higher performance with phatk than he is claiming, so something isn't quite right. |

It is not free. I still charge for hdminer. And I am still faster than today's best on HD 69xx. I benchmarked cgminer w/phatk at 691 Mh/s on a stock 6990, compared to my 708 Mh/s.
You clearly don't know how to run and optimize other miners. I get 704 on stock 6990s using Phoenix/Phatk. If you'd like to send me a copy of your miner I'll post an independant performance comparison. |

With only 21 pool shares, that doesn't count. Show something that can run 24 hrs at that output.

Deliberately hurting the private investments of thousands is not illegal?
LOL. By that logic everyone who sells their coins and causes the price to drop is doing so illegally. |
