This is an argument for the ownership part, but doesn't dismiss the history part.
Ownership is indeed trickier, but nothing says that you have to undo previous entries, you can add a new entry tagged with the "official authority" certificate.
Central authority will remain a big problem in the car industry, also because cars go over country borders all the time.
- sparkie 7y agoThe history can be managed by having every log entry be hashed and each new entry refer to the previous hash. Each time the log is updated, the new hash is reported to the vehicle authority, which can prevent modifications to the history. No blockchain needed. Of course, this can be sidestepped by having work done on the vehicle and not updating the log. How do you prevent that?
- koonsolo 7y agoWhich vehicle authority are you talking about? There is no such thing as a vehicle authority. You buy the second hand car with history, not the one without.
