Interesting. By this way reviews can't be forget by also people can't delete it on later stage.
I mean, people change their reviews from time to time. How are you solving this problem?
Hey kolesozw thanks for the question!
As you perfectly pointed out, our blockchain based reviews have these advantages. However, reviews can be updated in the smart contract by its owner during a small timeframe and then become immutable until the owner makes another purchase to the very same merchant.
