I'm sure this question won't sound that articulate because I don't know all the uses of bitcoin or blockchain applications, but is there a way to lock a file, or image, or website with bitcoin? Theoretically, the only way to access the thing is to "unlock it" with bitcoin, hence pay the owner of the digital object. I'm sure there are 1000 projects that have some similar shtick, but can this just be done with bitcoin? I feel like if it was possible and easy to do that could be a game changer. Curious about people's thoughts.
