| > "My ownership data" has value. perhaps not to you. But for people i interact with. I don't think you understood what I meant. I said it has no intrinsic value, meaning that it has no value in itself. > My education degree is something that I own. It can be very useful if I can quickly prove to the world that I indeed really have that degree. The fact that it is written in a blockchain that you have a degree has no value in itself, it only works if a necessary trusted third-party, the university where you got that degree, approves it. You are not in a decentralized and fully adversarial setting. You do not need (nor want, for efficiency purpose mainly) a blockchain to solve this problem. What you want is a cryptographic certificate (just like an X.509 SSL/TLS certificate) of your diploma signed by your university, which would play the role of a Certificate Authority, and which you can trust because the government that accredited your university to deliver actual diplomas has a root certificate (it acts as a Trusted Certificate Authority) and has signed the one of your university with it. > like Twitter allows to prove you own an avatar NFT Twitter is a central authority and could very well associate any "NFT avatar" with any of its users without relying on any blockchain. |
