Carnomaly is one of many companies that are trying to tokenise, and 'blockchain-ise' (weird word, but it sounds good so I'm gonna use it) car ownership.
The platform uses an NFT-based system - surprise surprise.
This is how it works.
You can scan your VIN (Vehicle Identification Number) and mint a unique NFT that stores service industry and odometer readings.
Apparently, you can also earn rewards whenever you store data about things like tyre changes, oil changes, repair counts and so on.
The rewards will be paid out in $CARR, the platform's token (on Polygon), currently worth $0.001977.
