thanks for the help

Allright, quoting this so you can't change it.

Now please send the 1 BTC to a trusted escrow. If you've done that, we can start talking.

Isn't it 1 mBTC? Tongue

Oh crap, I misread that.
In that case, I'm out. It was worth it for 1 BTC, but for a thousands of it? Not really.

10⁴² different probability and there're 10⁷⁰ different ~~public~~ private keys.
Also your number is a valid private key. If I were you I would do that;
- (probably it's in base10) convert it into base16
- go to here; https://brainwallet.github.io/#generator and click secret exponent tab
- base16 number to Secret Exponent
- load the pub key and share it with us Grin

if someone finds the number then (s)he will get the prize

why isn't it fine right now? Cool

Can you send the funds in escrow and make a hash of your number, so we can verify you didn't cheat?

If you do that, I'll give it a try. The answer can be guessed within 140 guesses.

escrow is no problem, will do that tomorrow but don't see why it's necessary, i'm not going to cheat Grin

how do i make a hash?

Go to this website: http://www.xorbin.com/tools/sha256-hash-calculator
Fill in the exact number with some extra random letters and numbers in order to prevent people to bruteforce it.
It should look something like this

Code:

*yournumber* AK$t4tsl445 (any random letters and numbers)

Keep those letters and numbers, so if we can't guess it right, you'll be able to prove that we indeed didn't guess the number right.

If you've filled it all in, copy the sha-256 hash, and post it here.

way too easy to cheat then. programs exist which can test many millions of hashes per second. there's also precomputed hashes available as rainbow tables.

That's the point of the random characters at the end. That's so you can guarantee that the hash hasn't been pre-computed and isn't likely to be cracked.

If you take your number, square it (multiply it by itself), add that square to your original number, divide that by your original number, then add 17, subtract your original number and divide by 6, is the result (but not your original number) 3?

yes, but that counts for every number Cool
