Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it

Pretty good performance. I'm at 10,000 keys/s, pretty slow, so I will get nowhere for values > #40 without trying to improve code or coding for GPU.

Anyhow, I think even with GPU we won't go too far...

Do you know anything about who created this 32 BTC puzzle?

A GPU cracker would take at most a year for solving the next 2⁵¹ address at 35,000,000 keys/s. I guess it will be cracked too in future, but for fun and not for money.

I don't know who made this pizzle.

Exactly.

One thing I was wondering is if it is possible somehow to tweak some ASIC miner out there to turn it into a cracker?

I have no idea if such thing is possible as I never used any ASIC miner.

Miners can only do sha256d. What is needed here is pubkey(ECDSA privkey) and ripemd160(sha256(0x04pubkeyxpubkeyy)). Everything else can be ignored if we compare to the ripemd160 hash. Its certainly possible to design an ASIC for this and it might even be profitable for someone to do so in the future.
