Revain is an Ethereum-based feedback platform proposed with the aim to mitigate review frauds. It arrives at a time when online trollers are continuously targeting legitimate businesses by fake and senseless reviews. At the same time, unprofessional businesses are hiring paid reviewers to mislead users about the quality of their products/services – to even launch online attacks against competitors.

Revain, on the other hand, proposes to combine blockchain and artificial intelligence to resolve review frauds. The platform does so by introducing an innovative Review Filtration Mechanism. This mechanism combines the power of machine-to-machine technology with manual moderation, to detect anything from language to tone of a review.

The approved/flagged reviews are then partially stored on the blockchain.

Overall, Revain makes a strong case against the paid review mechanisms and proposes a concrete solution to mitigate them.
