There are many restaurant review platforms available, but they are often centralized and lack transparency. Users cannot be sure if reviews are authentic, and restaurant owners have limited control over their reputation on these platforms. Additionally, traditional review platforms are often limited to fiat currency, making international transactions difficult and costly.
