They need to make a replacement becqause the alternative is to wait until SHA256 isn't good enough. I don't reall understand what are you trying to say, Man From The Future. SHA256 is just 1 of the 4 hashing functions that are used in the SHA-2 hashing algorithm! It's possible, yes, but it's going to be a mess and require lots of cooperation. So, better sooner than later because if later the mess will be bigger! |

You think they should wait until SHA-2 is broken to start looking for a replacement? Think about that for a second. If they think for a replacement there is a reason, right? If they think for a replacement after 2012 why you shouldn't? Or you intend to use SHA-2 until 2140? |

Bitcoin mining process consists of repeatedly increasing "nonce": payload = <some data related to things happening on the Bitcoin network>
nonce = 1
hash = SHA2( SHA2( payload + nonce ) ) It merely tries to find the right number. If SHA-2 is so secure then why have National Institute of Standards and Technology (NIST) announced an open competition for a new SHA-3 function to replace the older SHA-1 and SHA-2 after 2012? http://en.wikipedia.org/wiki/NIST_hash_function_competitionIs SHA-2 algorithm hard coded in the bitcoin protocol or not? Is it possible to upgraded it to SHA-3 after 2012? |

Easycoin, as I understand it, is not 'just a payment processor'. It is effectively a bank which issues its own form of tradable credits "backed" by Bitcoins. As I understand it, OP's idea is to sell insurance policies on bitcoin transfers to merchants that want to accept bitcoins from accidental customers. So far so good. It is an old business concept and it might be reasonable. What I do not understand is what insecure aspect of bitcoin transfers Atlas wants to cover? |

In other words, CampBX does not want to be a place for illegal activity! Sure. But according to this document: APPENDIX F: MONEY LAUNDERING AND TERRORIST FINANCING "RED FLAGS" http://www.ffiec.gov/bsa_aml_infobase/pages_manual/OLM_106.htmpurchasing bitcoins is illegal, because you don't know where purchased funds are going. In what country do they go?... So, you have to report every transaction to respective auhtorities!? |

The engine flags these accounts for manual review, and we can refuse the transaction or refund/close the account depending on severity. We are not tied into any of the 3-letter agencies.
But you are legally bound to autoreport those flagged transactions and accounts, right? The foundation of our operations is an active and prominent compliance program, and we are committed to maintaining full compliance with State of Georgia - Department of Banking and Finance regulations. |

Good morning everyone,
Good morning, Keyur. Good work. Just a quick question... We have hard-coded additional rules in our trading engine to thwart illegitimate usage of the platform and money laundering. Does that mean you are directly interfacing your platform with some of the 3 letter agencies? |

Due to this reversibility, people can purchase Bitcoins with their credit card due to the eliminated chargeback risk. Bitcoins should never be purchased with credit cards or other method of credit. Bitcoin is cash and should be purchased with cash, or we risk transferring all weak spots of a fiat money system to bitcoin system! Cash against cash, this should be the leading principle for all bitcoin exchanges. not really, as the money/wealth we can transfer from other systems into the btc system the stronger we get and the weaker they get. You can't transfer money/wealth from a credit card. Credit card is debt. Transferring money from a credit card is just transferring debt. And debt is not wealth, it is just debt! |

Abe or another competing open source, it is a much needed service. Following this thread...

Okay, how about re-phrasing it by saying that the prior certainty is doubled?
Before the nurse flashed the card, you were 50% certain it was whichever it turned out later to be.
After the nurse flashed the card, you were 2 * 50 = 100 % certain it was whichever it turned out to be.

As a logical block above is okay, but then the entire article should be rewritten as some assumptions won't be correct. You can't double the value of something by multiplying with 1, because 1 bit is, by definition, 1 binary digit - '1' or '0'. Unless, you can prove that 1 bit = 2. But then, what is 2? |

The reserve currency is a burden that no country wants, provided the country as an entity, could think. This is completely wrong. If your domestic currency is the world reserve currency as well this is not a burden, but a huge competitive advantage! Some countries are even willing to start wars to keep the status quo. |

“It rained in Oxford every day this week” or “It rained in the Sahara desert every day this week” - both remove 100% of receiver's prior uncertainty. What do I miss?
No, because the amount of information is not the same for both sentences, as rain in Sahara is much more of an unlikely event as rain in Oxford. I'm not discussing the amount of information, but if a bit of information is removing 50% or 100% of receiver's uncertainty. If you've learned about the rain in Sahara that doesn't make you less uncertain about the rain in Oxford! Same confusion goes here: He can’t see any details, so a nurse has agreed to hold up a pink card if it is a girl, blue for a boy. How much information is conveyed when, say, the nurse flourishes the pink card to the delighted father? The answer is one bit -- the prior uncertainty is halved. My answer is different. My answer is one bit -- the prior uncertainty is removed entirely, because pink card means girl. Unless, I don't understand what does 'flourish' mean in this context? |

I don't suppose you ever read Richard Dawkins' article The Information Challenge, in which he honors Shannon and provides a great layman's explanation of information as an economic commodity and the relevance of redundancy. I don't understand this conclusion: Shannon’s unit of information is the bit, short for “binary digit”. One bit is defined as the amount of information needed to halve the receiver’s prior uncertainty... Why is bit defined to remove only 50% of receiver's prior uncertainty? A bit should remove 100% of receiver's prior uncertainty! It is either '1' or '0'. There is no 1/2 binary digit?! “It rained in Oxford every day this week” or “It rained in the Sahara desert every day this week” - both remove 100% of receiver's prior uncertainty. What do I miss? |

During their 41 conference in Singapore last week, ICANN approved the motion to allow new generic top level domains (gTLDs) to be registered with their organization. That means any 'established' company would be allowed to register .WAHATEVER domain name. If .bit gTLD is registered through ICANN how head-to-head collision with namecoin network will be resolved?

I know no one asked me, but if you ask me... this is a pointless topic of discussion.
I don't know. What I do know, however, is the ssl cert for forum.bitcoin.org is issued by Startcom Ltd. - an Eilat/Israel based company. By the way, in the time of writing this they have just switched to a new ssl cert provider... LOL PS - Now is back to its original one. It is changing between StartSSL.com cert and server www.mineco.in ssl cert provided by GlobalSign nv-sa BE. What's going guys, somebody is laughing at you big time? The only browser I believe in is Opera, catching all security issues. |

I wonder why Russian exchanges aren't more popular too.
This is an easy answer. Russian ruble is backed by oil and gas which is better than gold. Polish welfare state is backed by debt, debt and debt. The same model as in the US. |

They remained un-phased because nowadays they are a satellite of the United States. To be correct whole EU is satellite of US (especially in a military sense) To be correct this is incorrect. Of course, there are many satellites of the US especially among Eastern European countries. Poland, however, is a very special case. They have the lowest orbit as a satellite of the United States among all EU member countries. |
