I have to cgeck the ordinals. The NFTs I know. But the NFT will give you ownership. But everybody can still see the content.

The thing that needs to be created is that you cannot “open” the file and consume the content (consume meaning reading, listening, watching) if you do not own the private key of that wallet/ of that thing.

Something like: here is the book. But the book is encrypted. Closed. You can’t read it.

If you buy THIS book, only you can open the book. And you cannot pass that book to others to open it.

There are two aspects. You can’t pass it to others. And you cannot open it.

If you pass it, you loose it.

And finally you cannot copy it either. You cannot multiply it.

I think with bitcoin we have solved two of these problems. You can not pass it and keep it. You cannot copy it.

But everybody can still see it. Open it. The blockchain is open.

When we solve the third: opening it, reading it, listening to it we will have gone to the next level.
