 - How asset metadata is updated. In BigchainDB it is possible to use `TRANSFER` transactions to change the state of an asset, in this case the mileage of a car.

 That's it, we have created a car asset, and every time the car travels new kilometers the `updateMileage` should be called with the new value of it.
