On_Chain Vehicle Indexing

We have adopted a vehicle indexing method which is simple, private and reliable by indexing hashed VINs (Vehicle Identification Number) into DVINs (Digital Vehicle Identification Number).

How this works:

• Every vehicle has a unique VIN

• Instead of publishing the VIN directly on_chain, CarrChain generates a cryptographic hash of the VIN

• The hash acts as the vehicle’s Digital VIN

This means that actual VINs are not exposed on the blockchain, the same VIN always produces the same hash and the identifier corresponds to a real vehicle, not just a random number.

CarrChain supports batch minting of vehicles ensuring the system is efficient and affordable to run at scale.
