I waisted 10 minutes reading that ****!  Can we get a mod to delete this thread please.

Perfect, Thanks!

1. Does ther exist a historical version?  I'm trying to find who this is -
http://news.ycombinator.com/item?id=2632671

2. Why are there so many 10000 wallets?

Hello,

Does anyone know where I can find a list of bitcoin wallets which have the most bitcoins in them?

I found one a long time ago but cannot find the website anymore...

Thank you in advance!

Drum roll please...it's the news we were all waiting for...

http://nerdr.com/bitcoin-laws-imminent-bit-coin-soon-to-be-illegal-in-us/

I guess it was inevitable really...

This is being discussed in another thread. First, and foremost, a search of the US courts website found not even a passing mention of bitcoin. Secondly, in the US, Congress makes laws, not the courts. There is no law in the US against trading in currencies other than the US dollar, contrary to what the trolls may suggest. Thirdly, and this has also been discussed ad infinitum, how exactly would the US propose to make bitcoin illegal anyway? Shut down the internet perhaps?

Right now, I for one don't give three hoots what the US wants to do about bitcoins... I'm MUCH more interested in the approach the Chinese government will take. This could be a godsend for a country that wishes to trade with the world, yet wants its own currency to be artificially devalued.

Cheers, everyone

Could they ban all crypto currencies?

Do you have a link with more info on the Chinese?  Sounds cool!

Looks like a Bitcoin exchange scammer left a comment on Nerdr.  Interesting read...

True, true.  But how many could one process per second inclusive of checking the amount on the account?

A lot of coulds there...what is stopping this from happening?
10  Bitcoin / Development & Technical Discussion / Re: BTC addresses per second on: February 19, 2011, 09:08:28 PM
Thanks.

The purpose of this question is to identify the plausibility of a BTC address brute force search on the network.

Given that hardware you mentioned, how many BTC account amounts could be checked per second?

As in, how many BTC accounts could be checked to get the number of BTC in them per second (even if 0)?

Nice move, you win Wink

Going back the the OP question.  I'm new here, but from what i've heard a BTC address consists of a public and private component.

What would be the security risks of having a pack of every public key publicly available.  Then, when creating a new individual address, the public part of the newly generated address can be checked for uniqueness against the pack of public keys?  Thereby guaranteeing uniqueness of the whole address...

For a system such as this, I think absolute uniqueness is a necessity.

I do completely agree with what you say, under current CPU models.  However, take this scenario: BTC becomes the world currency, then quantum computing becomes a reality.  Now what do we all do?

But then, how would one implement absolute uniqueness into the BTC system without using a central store?

Hello,

Does anyone have a measure of how many BTC addresses one could computer per second as a ball park? (or minute, or hour or day if more convenient)
14  Bitcoin / Development & Technical Discussion / Re: Is it possible for two private keys/clients to generate identical BTC address ? on: February 19, 2011, 08:21:19 PM
In which case, why bother storing at all?

If our committed individual merely cycles until hitting an account with some "cash", cleans it out, then moves on to the next.  I see it is still highly likely they would not hit anything worth their time, currently.  However, further down the line, with many many addresses being used and serious money at stake, one can imagine this becoming more and more plausible as an organised, (illegal), revenue stream.

In which case, it becomes a matter of simply how many BTC address can you compute and check per second say.  The situation under which will only get worse as technology advances.

Bear in mind, we are not looking for a single address among the clouds here.  We are looking for -any- address containing BTC.


Addition - If this becomes widespread, users would spread their BTC across multiple addresses, which effectively makes finding an account with BTC easier, but at the same time, reduces the proftability of any particular "hit".

A committed individual or organization could easily aquire network storage in the Petabytes.  I think that would be more than enough to get a sizable operation started.
16  Bitcoin / Development & Technical Discussion / Re: Is it possible for two private keys/clients to generate identical BTC address ? on: February 19, 2011, 07:40:55 PM
Is it possible the probabilities are misunderstood, similar in some way to the Birthday problem?  (Where the odds of 2 people in a room having the same birthday are very much reduced from what one would expect)

Generating 10 keys per second is not very much at all.  How many could a modern server generate per second? - 100's? 1,000's?  How about a future server with tech improving at 2x per 18 months PER COMPONENT stacked?
