So... its been over a day and haven't gotten repayment. Seems like he ran off as expected, all for $1 worth of btc  . It's ok, I won't lose sleep over this. If you expected it, why did you give it to him? Even if its very little, it would've been put to a much better use if you gave it to something like Sean's Outpost. Anyway, leave negative feedback for him. |

when i'm mining with guiminer i do accept shares, is guiminer gooed enough for this?
guiminer-scrypt for scrypt coins. Also, did you add the "--scrypt" to your .bat file? |

What does this mean 0.003 BTC/GH. I want to buy a mining contract but i know nothing on how to get started? please help me atleast tell me where should i post this?
You're probably looking at PBMining, and all it means is that it costs 0.003 BTC per Ghash. |

Basically, PPLNS means that you must be mining in the round in which blocks are found by the pool, otherwise you'll get nothing. PPS is Pay Per Share, which usually has higher fees but you will get paid even if the pool doesn't find a block.

Hello,
My sincere apologies. I am a complete novice and know my way around computers in a very basic way.
The story is that i registered with slushes pool, created a wallet and because i didnt understand those command prompt type things i am using guiminer.
Now I can mine fine on the laptop which has a Nvidia geforce GT 520m at about 9 Mhashs's which i read is pretty poor.
I have an average graphics card in my htpc which is Radeon HD6770. I simply downloaded guiminer to the htpc, typed in the miner login details on there and it sits about 130 Mhas/s.
The problem is that in the summary view of guiminer running on the htpc nothing is being accepted or showing as stale... where as on the the laptop if I come back after 5 minutes there will be a few shares and stales.
Am i missing something glaringly obvious?
Thanks for reading.
With 140 MH/s (your htpc+laptop), you can get 0.0000042 btc (420 satoshi) a day on average. IIRC the minimum payment threshold on Slush is 0.01 btc, so you need to mine 6.5 years to get a payout, assuming the difficulty remains constant. Now, maybe you would reconsider your plan.  Just spend the time on bitvisitor and landofbitcoin you'll earn way more Best bet is get new mining equipment (i suggest not GPU), or just buy BTC. No, don't buy mining equipment. Buy BTC directly, its price will rise, and mining equipment requires, time, effort, and money. |

Bought $20 worth of PayPal, was a bit expensive, but w/e. Quick and easy.

1. Your hub probably doesn't supply enough power for more than six of them.
2. Erm.... No one uses Gridseeds to mine bitcoin, you know.
And yeah, to overclock a 5-chip gridseed you need to solder resistors (voltmod).

We are willing to use our site as collateral to insure no interest payments or the loan payment is missed. Meaning, if we default you will have control of our domain/brand/server/customer list/advertising accounts/marketing material/modules, ect.
Worthless, altcoins are required How is that worthless His whole website/domain etc could be worth more than the loan it self. As well as the fact this loan is going towards his website so it's most likely going to the the same value if not even more when you sell A unique collateral sure but it's a good one. Altcoins are not the only collateral, and I see <5% of the loans actually use altcoins as collateral because they can just get their BTC by exchanging. It is worthless. Collateral is something that has a value equal to or more than the value of the loan, that can be sold quickly and easily for said value.Where can you sell such a site? There's no "market price" for it, and how much it's worth differs from person to person. |

Well, I think people should try to keep thinking of ways to attack Bitcoin.
A new idea can come from any mind.
That said, I agree, the devs are very smart people and have had
a lot of Bitcoin experience. They are usually several steps ahead
of the crowd.
i know thats why i didnt want him to totally give up, i wanted to see where it lead to and find out if he actually done much research and found a flaw. turns out he was a standard worry-wort. I didn't do a lot of research, it's just something I came up with. Can someone expand on how the timestamps are validated? |

what the OP is trying to say is that knowing difficulty is changed every 2100 blocks. he will set up a private network of 2 PC's and at block 2098 he will set both computers time to be year 2100, thus as mining 2 more blocks. in this closed network. then the protocol in his theory will see that the blockchain has not mined blocks for 85 years and then give him super easy difficulty.. now the reality. when he rejoins the network he wil be all alone on his fork and everyone else will mine as usual not realising he exists, his coins from those 2 blocks would show as invalid and unspendable (wont confirm if he tried to send them) and he will get on with his life. OP you also have to realise that you trying to (in basic principle) solo mine block 2098 and 2099, would be still at an extremely high difficulty before the change, which unless you had a asic farm, would take you not 20 minutes.. but days or weeks if lucky.. so dont waste your time on this. many thousands of people have been there, done that. so heres the T-shirt  the other theory is to gather soooo much hash power to rival Ghash.oi etc. that if lucky he is the one that mines the critical block 2099 and it shows a timestamp of the year 2100.. goodluck, have you got over $10mill of equipment to try? Of course, a regular person wouldn't be able to do so, but Even a small pool like Bitminter, or Bitmaintech's AntPool, or KnC's "Testing Facility" could easily accomplish this without controlling 51% of the network. After they find that one block, which wouldn't take long, they would be able to start the cycle. I think this deserves a bit more attention. I don't pretend to know enough to comment on the specifics of such an idea. I do think as an academic exercise it is good to be aware of this kind of stuff in order to stay ahead of people that would try to game the system. I don't believe most such attacks would succeed in getting a bunch of coins, but they can cause chaos and fear which does affect our wealth. If no countermeasure is put in place, the attackers will just grab all block rewards with very little effort, and all coins will get mined in very little time, so it is a bunch of coins. |

So I just came up with an idea, but a very rough idea, as to how an attacker can carry out a 51%-attack-like attack.
Basically, as far as I understand, the Bitcoin Network knows its time based on what the nodes relay, and it takes an average out of it.
Well, an attacker could create their own fork of the blockchain when it is 1 block away from difficulty change, with a small number of nodes that only he controls, and change the time of the nodes. This would make the network "think" that a lot of time has passed since the next block was found, and all they have to do is find that single block. Once it is found, difficulty would dramatically decrease on their fork of the chain, since a lot of time had passed before blocks were found. Then all he needs to do is continue mining until his chain is 1 block away from difficulty change, and repeat the process. He can make his chain longer than the main one easily, and then broadcast it. This would effectively make the "official" blockchain fork.
I have no idea if this will work, since I'm not that into the tech of bitcoin, and I hope this isn't possible, and for someone to explain why.
Difficulty is part of the calculation of the length of the chain, so the fork would eventually be abandoned. I don't understand what you mean, please expand on it. |

Yes, create another address and send your coins there. Backup your wallet.dat again or write down your private keys.
-snip- Assuming that the answer to the first question is "Bitcoin Core", and the answer to the second question is "No", then you need to create a new wallet. The lost wallet already has access to the next address that you'll create in the current wallet (and the address after that, and the address after that, etc...) -snip- Oh thanks man. I didn't know that, and I retract my advice. I just learnt something new, lol. |

My grammar is bad, because I am Brazilian and I'm not fluent in English.
Unfortunately I don't know what collateral can give. Any suggestions?
Most people use altcoins here. Or you can ship gold or something to a trusted escrow. |

Yeah, but those sites may very well be scams. |

No collateral, no loan. This isn't safe, plus your grammar is quite bad.
Social Information isn't collateral, collateral is something equal to or worth more than the loan, and can be easily sold for said value quickly.
