I hate to be that guy, but in this case I think it's appropriate to say that "Blockchain" solves this problem. The core idea behind Bitcoin and (some) derivatives is that it enables digital objects that cannot be copied and have a distinct owner. You are not wrong that from a technical perspective this is a very hard problem (digital objects are just bits of information, and there is no way to restrict making a copy of that), which is why some people felt like Bitcoin is a truly remarkable technical invention. But the practical side of it seems to problematic still (as far as I know there are virtually no successful uses of this technology in digital marketplaces outside speculation platforms)
- andrewla 2mo agoBlockchain solves the double spend and ownership problems, but it does requires (a) that you be connected to the internet to establish or transfer ownership, and (b) that any consumer of encrypted data respect the blockchain state as well. If I have a video player and I give it a video that I downloaded with an ownership token, that player needs to either confirm that the token is still valid and deny the ability to play the video (even though it could), or it has to get a decryption key of some sort from the blockchain and use that to play the video, and further guarantee that said decryption key cannot be saved or copied. Blockchain does not solve this problem.
