All of this could be done without blockchain. Once they sign a signature with their private key they can't unsign it later. Once you attest something you cannot un-attest it.
Just make the public key known and sign things. Please stop shoehorning blockchain where it doesn't belong, especially when you aren't even giving any examples of things that blockchain is doing for you with 100000x the cost and complexity, that normal crypto from the 80s/90s cant do better.
If you've been saying this for a long time please stop. This will solve nothing. It will be trivial to bypass for malicious actors and just hampers normal consumers.
Anybody can also verify it if they just host the hash on their own website, or host the video itself.
Getting the general populace to understand block chain implementations or how to interface with it is an unrealistic task
What does a distributed zero trust model add to something that is inherently centralized requiring trust in only 1 party
Blockchain is the opposite of what you want for this problem, I'm not sure why people bring this up now. People need to take an introductory cryptography course before saying to use blockchain everywhere.
First blame the thief. But then in the same breath blame the manufacturers that refuse to sell cars with meaningfully working locks. If you understand the tech many car companies keep selling cars that have locks that are about as secure as a zip tie.
The FGC-9 is a gun designed to be built only from common hardware store tools and a shitty 3d printer and has been used by even the myanmar rebel forces who built it themselves. (Also you can build 3d printers themselves from hardware store and hobbyist electronics store supplies).
Guns are just metal tubes with some extra bits, as knowledge and materials get better, making them gets easier. You're making this statement like it hasn't been a common thing for years
No, it's the lack of support in web APIs. Every api is based on width and height, viewport width, viewport height. Nothing allows you to find the angle of the display, rotate DOM elements to align, wrap based on diagonal boundaries etc.
