Its not impossible, but only if he manages to buy up most of his debt through sock puppets at a few cents on the dollar, and then "repays" himself in full.
Anyone selling Pirate debt should make a contract with the buyer that if pirate pays out, they are entitled to (say) 33% of the amount.
In that case, the buyer will only pay 67% Why not simply sell only 67% of the debt? That's just equivalent |

ABCPool.co states that "A cheater can submit only shares and withhold any blocks found. This way the pool must pay for the shares, but will never earn anything because it does not know about the found block."
how can someone do it?
can it be done with a miner?
You may do so to hurt the pool but you will never profit from doing this. Satisfied? |

is there a way to join two pools with the same hashing power by submitting the same share to both pools and keeping the block's when found by not submitting it to the pool.
NO, NO, and NO |

Just use a brainwallet. That way your bitcoins are not stored "offline"... they aren't stored anywhere at all. There would be no reason why people would come to your house looking for bitcoins, there would be no point. The only way to get them would be coerce you to give up the passphrase. I can go into more details about this (it's a pretty simple system -> you still use an offline computer to sign transactions, but the offline computer never stores the private key).
Why do you say there is no reason why people would come to my house looking for bitcoins? As I said in the OP, my name and street address are fairly easily associable with my online identities. Couple that with the fact that I would be running a business where anyone could see the exact amount of Bitcoins I am holding at any given time, and that number of Bitcoins may increase to a significant number (thousands or tens of thousands of BTC), and I can see very good reason for people wanting to "pay me a visit". Even if you really have the private key stored in the bank vault, robber of this kind simply won't believe and you will get shot anyway. The easiest thing for you is to do your business anonymously. |

Not solved, because you are just promoting it to a wrong target group:99.99% of Chinese bitcoin users with good English ability know Internet circumvention. The potential harm outweighs the benefit. OK, and would you say that's a large portion of current Chinese (中國) Bitcoin users, or a small percentage? I don't know, and that is irrelevant to our discussion. If you post in English, your target population is restricted to those who read English. In China, only well-educated people use English and they should know every method to fight with the wall. |

Well that's a good idea.
You are just promoting it to a wrong target group:99.99% of Chinese bitcoin users with good English ability know Internet circumvention. If your programme is not related to bitcoin, "off-topic" is the right place for you. Although your programme is mainly for people in Mainland China, the group is called "中文" (Chinese Language), not "中國" (China). Many people around the world speak Chinese, and the group is not reserved to people in Mainland China. |

I am not sure if you have ever experienced the Chinese firewall. If you just learn it from media, obviously you won't really know how it works.
The argument is, promoting anti-firewall here will alert the firewall and the wall will come A LOT EARLIER. The wall will (either automatically or manually) filter any sites with anti-firewall keywords.
In other words, even this discussion might trigger it. You're screwed whatever you do. As long as we use English, the risk is minimal. Then Let him post in the Chinese forum, but use English. Problem solved? Not solved, because you are just promoting it to a wrong target group:99.99% of Chinese bitcoin users with good English ability know Internet circumvention. The potential harm outweighs the benefit. Again, I hate the wall and I believe every Chinese bitcoin users hate it. I also hate self-censorship but we shouldn't take risks without a good reason. Just think again why Satoshi wanted to keep distance with Wikileaks. |

The number of internet users in China is larger than the total population in the US. The trading volume in btcchina.com, however, is <2% of mtgox. Bitcoin is China is still in its infancy. Please don't kill it with the heat of anti-firewall.
Yes, the oppressive government will eventually find bitcoin as a threat to them. However, we need more Chinese people learn it before it is firewall-ed. When the government really try to wall bitcoin, Chinese people will learn to circumvent it to protect their wealth.
You do know that Gox trades in more than USD, right? There's CNY and HKD activity on there, too. Besides, these two statements cancel each other out: Please don't kill it with the heat of anti-firewall.
Chinese people will learn to circumvent it to protect their wealth.
The more Chinese Bitcoin users have a tool to circumvent it, the faster Bitcoin will spread after the wall comes down. It's in their best interest to get that tool to as many users as possible.

However, when GFW feels this community or bitcoin is a thread to them, they could block all bitcoin related websites nevertheless. What you are doing will make GFW feels this community or bitcoin is a threat to them Because it is. Sorry. Fact of life, oppressive governments don't like freedom. Especially economic freedom. I make this appeal to WikiLeaks not to try to use Bitcoin. Bitcoin is a small beta community in its infancy. You would not stand to get more than pocket change, and the heat you would bring would likely destroy us at this stage. That's two years ago. We're well past that stage now. Satoshi would no doubt rejoice at seeing that Wikileaks now accepts Bitcoin, and is thumbing their nose at the CC companies and governments alike.

There are plenty of circumvention tools already.
Yes. Except that most Chinese can't get them or don't even know they exist. With his argument, we should delete all articles about it on wikipedia to "protect" wikipedia, which is of course absurd . Yes, but as you have agreed, Chinese bitcoin users here should know these tools. By the way, bitcoin is a currency, a channel of payment, not an encyclopedia. If you want to advertise your tool in this forum, the best place to go is the off-topic section. |

Without Internet circumvention tool, what could Chinese do then?
There are plenty of circumvention tools already. |

Anyone who uses Bitcoin in China should have knowledge about circumventing the firewall already, so advertising this will do more harm then help.
Totally agree. I hate the wall but there is no point to advertise anti-wall skills here. |

Too bad you aren't even trying to brute force the full address. You might end up a few characters off!
No, the last few characters are just checksum |

Is there any Python code that translates private key (in HEX format) to an bitcoin address? Thanks!

不要迷恋51%，没看见现在已经没人讨论51%了吗？
你也不要輕視51%的威力, 請搜尋Coiledcoin和BBQCoin |

喜欢比特币的人依然喜欢,不喜欢的怎么都不会改变的.
鉴定完毕.请楼主封帖!
如果真的"不喜欢的怎么都不会改变的", 那bitcoin注定要失敗了. bitcoin要成功, 中國是一大關鍵. 中國有5億網民, 就算是只有0.1%使用BTC, 以現有的10,000,000個幣, 每人都分不到20個幣, 已足以令BTC升至天價. 但絕大部份人不了解BTC, 他們 (我最初也是) 認為BTC只是像Q幣那樣的遊戲幣 (甚至連宣傳BTC的人也這樣說! https://bitcointalk.org/index.php?topic=102038.0). 誰會願意用70元人民幣買一個可以任意濫發的Q幣? 我認為樓主的問題是有理由的, 但他看不到萬物都有弱點. 每天都用鈔票, 就誤以為手上的鈔票有政府背書所以很安全. 但事實上美元的幣值在過去一百年已貶了無數次, 美元=黃金的承諾可以一夜間廢止. 美國不停以新債償還舊債, 不正是一個龐茲騙局嗎? 唯一分別是政府可以印鈔, 所以不會即時崩潰, 而印鈔就是搶奪你我手上鈔票的價值, 是變相徵稅. 直接徵稅人民會反抗, 但印鈔便不一定會察覺. 美元有美國政府保護, 所以看起來是安全的, 但實際上大家都要向美國政府交"保護費". BTC沒有中央政府保護, 所以就要靠miner保護, 那50BTC就是保護費. BTC和美元相比, 最少前者的規則是完全公開的. |

世上沒有財富儲存和付款方式是100%安全的, 鈔票可以濫印 (正在發生), 銀行可以倒閉 (並不罕見), 黃金和信用卡可以被盜和造假 (每天都有), 但我們還是會繼續使用這些方法.
正在發生的鈔票濫印，或是銀行倒閉，並沒有使美元崩潰。因為政府在為之背書。 而為btc背書的是btc的分佈式安全算法。必須證明他是無法摧毀的（或摧毀代價極高）。但現在顯然還不夠。 美元在歷史上已經多次"崩潰", 最近一次在1971年. 還有, 世界上沒有東西是無法摧毀 |

世上沒有財富儲存和付款方式是100%安全的, 鈔票可以濫印 (正在發生), 銀行可以倒閉 (並不罕見), 黃金和信用卡可以被盜和造假 (每天都有), 但我們還是會繼續使用這些方法. 硬件性能的进步和成本的降低，是高速发展的，所以依托于计算力的安全永远都不是安全。 bitcoin依托于信心之上，摧毁一次就会出问题。摧毁一次的成本并不高，因为投入的硬件还可以用来干别的。 飞机撞大楼都有，更别说只是坐在家里指挥一下bitcoin的网路袭击。
依託在計算力pk上的算法，很難說是堅不可摧的。例如ASIC的廠商直接用ASIC來攻擊（而不是銷售賺錢），他們顛覆btc網絡的成本就會很低。
实在告诉你，我们所知道的前3家ASIC研发者，都是准备合规挖矿的、保护bitcoin网络的。 ASIC攻击者只能是后来的厂商，那么这位攻击者面临多位合法ASIC的保护，门槛不低，成本不低。 ASIC研发仍然属于高风险、高投入的活动，能够合法挖矿赚钱，却要颠覆btc网络，该是怎样的丧心病狂、怎样的宗教意志啊 將來還會有BSIC, CSIC...計算力的突變是可以預期的
不会有BSIC和CSIC的，你说的应该是计算机硬件技术的突破性进步。ASIC是一大类技术，我们用的GPU、CPU都是ASIC的一种，没什么特别的。 bitcoin的强健，很大程度上是因为其结构的简单。以后如果有新的硬件技术出来，除非最先掌握该技术的厂商决意与bitcoin为敌，那么这项技术就可以被所有的人商业化应用，其中也就包括bitcoin挖矿设备的开发商。而能够开发出这样牛逼、颠覆性硬件技术的厂商，应该是商业组织，而不是一个具有宗教色彩的bitcoin hater，花了那么多研发费用，不好好卖钱，而用来做黑客攻击。 总之，一个神一样威武、却又蛇蝎一样仇恨着bitcoin的存在，不能完全排除可能性，但是要在现实中出现，需要依赖的假设条件太多。 難道btc的未來就把握在大的硬件廠商之上嗎？
btc的未来是把握在所有比特币经济参与者的手上。 一开始，这个未来只把握在2个人身上，那就是中本聪和那位牛逼的cypherpunck（我一时忘了名字了），那时，这个世界上只有两台电脑在做bitcoin的miner，如果有人用10台电脑攻击，bitcoin就over了。 后来，bitcoin的未来就把握在全球矿工的手上。我们买了无数的高端显卡来挖矿。这个时候要颠覆bitcoin网络已经需要大的投入了。矿工之间也有社会分工的进一步细化。一开始都是solo mining，然后就有人来建立矿池，有人继续建算力，矿工就分化成矿池管理者和矿工。开始矿工用CPU直接挖，后来用GPU挖，就需要写专门的挖矿软件，又有挖矿软件编写者出现。为了进一步降低能耗和固定投资水平，又有FPGA和ASIC开发者出现。FPGA的门槛相对高，ASIC的开发门槛十分高，这提现了分工的细化。 这种分工的出现，并不是独立的，他们依赖彼此而生存。我相信人类是一种从远古时期就进化出了协作本能的动物。这是我们人类在力量、速度都逊于其他物种的情况下却能发展壮大的重要原因之一。挖矿硬件商只是参与者之一，虽然是非常重要的参与者。硬件厂商只是所有矿工分工的一环。硬件厂商之间会有多个竞争者，竞争会平衡很多问题，解决很多担忧。 |
