Corporations like Louis Vuitton can use their own block chain but it’s private not public. There is no trust. Louis Vuitton knows if they use a public blockchain like Vechain everyone will know where their products come from. Like being made in China and all of a sudden the luxury brands are not so luxurious anymore, the mystery is gone because you can see its whole route that it took to get on your front door. They will fight this but there are plenty of other companies outside of this one.
