Revain

Revain is a unique blockchain-based platform that allows users to give reviews that cannot be deleted or changed. It is the first blockchain review platform that is completely immutable and incorruptible. This platform does not have a third party, and uses two layers to ensure reviews are authentic and constructive. These layers are the filtering layer that uses Artificial Intelligence (AI) to analyse reviews and a second internal layer that determines the review to be published. An additionalShow more [+] RSS (Review Snapshots Storage) ensure that the platform is immutable. It also has a stable internal coin RVN that is used to reward users.

The platform is also unique in that it has two tokens, the R and the RVN tokens. The R token was used for collecting funds during the ICO (Initial Coin Offering), while the RVN token is used to reward contributors who post constructive content and punish those who contribute useless reviews. It is possible to convert RVN tokens to R tokens.

Being an erc20 token, it is supported by wallets such as Infinito and others that are compatible with erc20 tokens. Its ICO ended on September 2017 and raised $12.51 million.

The team behind this project is comprised of experts from various fields including Rinat Arslano, the CEO, Sergey Omilyanchuk, the backend developer, Vlad Bocharov, designer and Bogdan Savin, the community manager among others.
