Is it possible to use Vanitygen (or something like that) to do it then? Obvoiusly not a CPU, but big GPU farms?

Yes, you can instruct Vanitygen to try and attempt to generate a private key for that specific address.

However, you won't be around to see the result. Nor will your grandchildren. Or our sun for that matter. The address space is simply that large.

Even if a bunch of giant GPU farms get together? Im talking 100's of GH scrypt mining.

Pretty much what everyone else said here. Cryptographic hashes are one-way math functions.

There are some interesting threads on how much power or time it would
take to brute force a key. It is not possible
with the computers of today or even tomorrow. Search the forum, you
will find a lot of interesting discussion.

By the way, Bitcoin mining transitioned from GPU to ASIC.
Bitcoin uses SHA-256 , not Scrypt for proof of work, as
well as its hashing function within ECDSA.

I know bitcoin is using ASIC. Right now VanityGen is for GPU only.

Okay, I figured. People wouldn't be using BTC if it could be cracked. Thanks for the answers!

even if you used all the matter in the solar system to construct an ASIC farm, and then use the sun to power it, you still won't be able to calculate it before the heat death of the universe. 2^256 is just that big.

Stop using branwallets

We're talking 2^160 possibilities. So divide that by whatever hash rate you want and you'll see.

Just wondering. If you could get the Public Key of the account with the most bitcoins, could you calculate the private key?
