Come on, you don't need to check the balance, you just need to get address of puzzle #120, that's all.
Maybe I missed something
What address are you talking about? You posted a 120-bits private key and said that three hex chars were intentionally changed. What address were we supposed to find, from the 14 million different possible alterations?[/quote]
This is what shocks me. You are very very active on btc puzzle thread and 1st to comment on this thread.
It was simple and luck just compared each key while changing 3 characters again public key not address.

W T F. @RetiredCoder, unless I missed something obvious, then you just told us you found the private key to puzzle #120, which is the first solved puzzle for which the private key was not disclosed until today. So the congrats are on you, it seems.
I never attempted to actually check if the priv key matches the actual puzzle #120 since I knew the solver never published the key. So, are you 3Emi or...?
