I have a question that I hope the community can help me with. If I wanted to make a "treasure hunt" website, my obvious choice would naturally be to go with BitCoin as they fit the integration with the internet that no other currency can do.
But would I be able to "burry" BitCoin's on a website, where I could ask people to do X and Y before Z would appear thus giving access to a BitCoin? Would it even be possible to place a downloadable BitCoin on a website so that people can more or less download it and import it into their wallet?
Would be great fun and could potentially be made into a game online where prizes are BitCoin's.
How you might do this:
1) Send your bitcoin "prizes" to a separate address each. If need be, check the blockchain to make sure each address only has that amount (if you're worried about an address holding change.)
2) When rewarding someone with a prize, give them the private key for the address you sent that prize too.
Note that you may have to explain how to access the funds, since importing a private key into a wallet isn't exactly a streamlined feature of the client.
It might just be easier to ask them to enter a bitcoin address, and then automatically send them their prize, or send it manually later.
