The way I read the article, the “worth millions” is the sum of the ransom demand.
The funny part is that the exploit is in the “smart” contract, ya know the thing that the blockchain keeps secure by forbidding any updates or patches.

Another question is: why would you need it for a key?
Long-established public/private keys and signatures are used in this way all the time to control access to servers around the world. No blockchain needed. Blockchain is helpful when we all need to agree on a series of events.
Homes are a nice example of where you can have an isolated system which knows what it needs to about you (e.g. a public key) without sharing or cross-checking anything with the world.
The chain would be used to establish who owns the home.
That sounds more like a land registry system, than a key.
Just like the NFTs in the article! Great idea
