Can standalone program securely store its own bitcoin?

[williamevanl]

I've been thinking about autonomous applications recently and I'm wondering is it possible for a standalone application to be able to store a private address and send from it without exposing it in any way?

Thanks,
-Will

Are you talking about person A creating a program and putting their own BTC on it, then giving the program to person B who does not own the BTC for the program to only spend the funds under certain circumstances?

If this is what you are asking about then I would say almost certainly no. It would be too easy to make a copy of the program and attempt to reverse engineer it on a computer that is not connected to the internet, or on a computer that appears to be connected to the internet/bitcoin network but really is not.

Bitcoins are calculated based on blockchain transaction data. Your wallet stores addresses, nothing more. The blockchain stores only transaction data.
