Looking at how he "thinks" his solution will work, He doesn't understand the concept of destructive operations.  Think of it this way: The simplest hash function is %2.  Basically, given any input, find the remainder after you divide by 2.  It simplifies things down to a keyspace of 1 bit, and obviously there's lots of collisions.  However, given that information, there's no way to go backwards to the original number.  If I say the "hash" is 1, it could be 1, 3, 5, 7, 9, etc.

SHA256 has the following destructive operations:
6x non-carrying addition
Shift right
I believe the combination of ANDs and XORs ends up being destructive.

That's just in one iteration, and there are 64 iterations per hash.

If he succeeds, bitcoin compromization will be the least of our worries.  SHA256 has stood up to mathematical analysis for many years, not just from the bitcoin community but from the entire world.

Actually, I love this idea haha.  Though, I think it'd be cooler to print shirts with the current price as you sell them, so people wouldn't have to deal with it, or couldn't forge it.

Technically, the CPU power used when attempting to solve a block keeps it competitive.  THAT'S the value you add when you don't solve a block.  Which is ridiculously low when CPU mining.

What kind of hashing rates are you getting on the other cards of that type?

You don't happen to know what the hashing rate on these are, do you?

Wait, new york?  Can I pick it up in person?  I'm in Boston, and I'm going to school in NY soon, been planning a trip out there to see the campus anyway.

Payable in bitcoins?  What's the cheapest shipping method you offer to Florida?

What are you charging on top of that for the shipping?

Where are you located, so I can judge shipping costs?

I'll take some too.  100 please. (Just kidding, of course.)

Nice way to backtrack.

As for your argument against my English, the point of language is to communicate.  If my sentences communicate my ideas cogently and concisely, then I consider it to be good English.  Excessive perfection of grammar and spelling is only something for uptight literature snobs to occupy themselves with.  You, however, are having difficulty both communicating your ideas and understanding the points that everyone else in this forum puts forward.  THAT is poor English, not misconjugating a negative gerund or misplacing an apostrophe at 3:30am.

Keyword most.

It seems like people like this have been cropping up since bitcoin began.  I remember a year ago having almost the exact same discussion with someone (even back then, when bitcoins were just barely worth more than the electricity it took to mint them, and everything was done on the CPU's and kilahashes.)

They all have a few similar features.

1) Very Poor English.  I think this leads to a lot of friction for them learning about how the system ACTUALLY works, for communicating their ideas well, or from considering the points that people rebuttle with.

2) A fundemental misunderstanding of economics/bitcoin.  "mining" being a scam?  The Mining is what holds the whole system together, what makes it cryptographically secure and worthwhile to begin with.  Maybe if you understood the whitepaper, or read a bit of the code, or took 30 seconds to think about WHY these choices were made, you'd understand that.

3) An unending, unquavering, unpersuadable attitude towards "the bitcoin doomsday" or "the Great Unjustice".

I wonder if Bitcoin, due to it's complicated nature, is doomed to be perpetually fraught with these "Throughput"s?  (Have a read of http://forum.bitcoin.org/index.php?topic=547.0 for a good laugh.)

What price are you looking at?

Anyone have a confirmed trade with you?  Do you have anything to point to for your reputation?

Not to hijack your thread, but while dgamer5000 is unavailable due to workload, if you have any other requests I'm also a very experienced C# programmer (C++ for 6 years, then switched to C# for the last 5).

Almost, but one minor caveat: The group with more people/miners would be accepted as the proper block chain.  If mexico had more users in their network than the US (given the relative sizes of the countries, I doubt it) then it would be the US transactions that would need to be re-validated.

I first read this as you betting 500,000 and 360,000 bitcoins and choked on my drink.
