You're missing my point.There is no crypto authority. Anyone can verify transactions themselves. That is a core point
It's the exact same discussions I had about computers and smartphones. People would say who cares about some random web pages or apps and come up with all kinds of reasons they feel uncomfortable with change
For something like proof of attendance I think the difference is how the data is recorded rather than issued. Blockchain transactions can't be tampered like a central file on a computer can. You can't retroactively get that token or edit them after the fact.
This is huge for things like supply chain management. Sure there are always ways to mess with the system but let's be honest we are currently working with 19th century records that everyone knows is extremely easy to forge and tamper with
We can't really say exactly how they will be used but we can see there is massive potential.
You still have to trust that the authority who put it on the blockchain is who you think it is.
I could go put it on the Blockchain that I have an MIT degree, then all I have to do is put that key on the MIT website.
You can make a write only log file, you don't need a public blockchain for that.
I agree there is potential there, but there are a lot of holes to be filled.
