Revain is an online platform for Ethereum blockchain-based tokens reviews designed to allow developers to receive constructive feedback about their projects. The protocol also incentivizes authors to provide high-quality reviews. Revain was the first platform to combine the features of traditional review sites and blockchain technology. Revain’s ultimate goal is to create a legitimate and genuine feedback structure for all global products and services that utilize emerging technologies such as machine learning and blockchain.Revain implements artificial intelligence tools and a manual review system to ensure the high quality of reviews. The core features of the protocol reviews: Revain uses only original content from a diverse range of experts on its website. Stable system: the protocol runs on two different tokens the REV and the RVN allowing for smooth functioning of the system. The RVN token helps facilitate interactions between users on the platform. Immutable information: The system does not allow both regular users and Revain itself to edit the information of other users.
