- Revain (R) is a blockchain-based feedback platform.
- Against this background, the idea of creating the own fair platform, on which anyone could share their experiences of working with a certain company, appeared. The open blockchain technology is able to solve the problem of managing customers’ feedbacks. All users’ comments will be stored in the registry, respectively, it will be impossible to change or delete them after publication. Before publication, all comments will undergo a two-step verification. This is necessary to weed out the false comments. With this idea, the developers conducted an ICO in 2017 and collected over 9 million dollars on it. This is how the Revain project appeared, the main task of which is to control honesty and transparency of comments left on the Internet. This platform has protective mechanisms against bots attack, in the form of restriction – one user can leave only 5 reviews per day. All comments will be stored in a special repository, the algorithm of which is based on a smart contract Ethereum. Because of this, the possibility of deleting reviews is excluded
