In the real world, we often make purchasing decisions based on reviews from previous buyers. This is very common in evaluating a product, service or business. So what about in the blockchain space? The answer is also yes, even the reviews are more public and transparent. Prominent among the development platforms in this field is Revain. So what is Revain? Are the reviews through Revain really potential and transparent? What role does the REV token play? All these questions will be answered by TraderH4 in the article below.
What is Revain?
Revain is a platform that combines today's leading technologies including blockchain technology, AI and IoT for users to make user reviews about products or services in a transparent and fair manner. In addition to Revain, there are other prominent review platforms such as Yelp and Trip Advisor, which encourage users to write independent, objective reviews.
Revain is built on the Ethereum platform, providing an immutable rating system for evaluating applications and exchanges in and out of the blockchain space. Businesses and projects also encourage users to leave feedback on the quality of products and services. Revain's ultimate goal is to provide authentic and high-quality user feedback on all global products and services.

What problem was Revain created to solve?
Currently on online review platforms there are a number of outstanding problems such as: Fake accounts, spam, untrue paid reviews... Besides, review sites do not transparently, edit or remove posts that are detrimental to our products and services. Because of that, customers have almost no interest in leaving reviews because it doesn't get anything but also wastes more time.

Revain sought to eliminate this reality and sought to put in place a rating system that was as objective and transparent as possible.
- To realize that ideal, Revain uses blockchain technology to ensure decentralization, transparency, immutability (non-editable) and encourages users to leave reviews about services/products.
- Previously, articles had to go through a high-level screening process using IBM Watson's AI. That purpose is to identify unhealthy, malicious reviews and promptly stop them before posting on Revain's ledger.
- In addition, to ensure transparency Revain uses the Ethereum blockchain to store snapshots of initial reviews. This helps to collate, compare and ensure posts have not been changed or deleted over time.
- Customers who leave a review will also receive the project's REV token as a small reward, incentivizing the user's review activity.
How Revain works
To better understand Revain's rating system, let's dive into the details of how the project works.
Revain's rating system
First, any user after purchasing a product or experiencing a service can leave a review on Revain's website. These reviews will then be filtered according to the following process:

- AI Filtering : All reviews, input data will be run on the Review Automatic Filtering (RAF) system. The purpose of this AI filtering is to eliminate spam articles, fake reviews or signs of plagiarism. In this step, a large part of the malicious content has been removed.
- Manual Verification : AI-filtered reviews will be sent to businesses, organizations, and projects for approval, comments, and a decision to accept or reject.
- Moderation : In the event of a dispute between the two parties, a moderator will be included to investigate, evaluate and make this decision. Once the truth has been exposed organizations, businesses, projects or users will be penalized for publishing false, malicious content. Even in severe cases they will be suspended.
Revain's Reward Mechanism
For users who have had successful reviews will receive RVN tokens and experience points. When the accumulated experience points are large enough, users will have access to more new services and tasks to conquer bigger rewards. On the other hand, users and organizations can completely be fined and have to pay fees if they submit inaccurate and untrue reviews.
Features of Revain
Usually a project will only use a single token, but Revain has 2 tokens, RVN and REV. Each token will have different roles and tasks. Specifically, the RVN token will be used to operate the project's ecosystem (reward, penalty). Meanwhile, the REV token is used to trade on exchanges or change to the cryptocurrency of ICO projects on Revain. In addition to tokens, Revain also has the following outstanding features:
- Using artificial intelligence: Revain's assessment service has close cooperation with leading high-tech AI systems of IBM (International Business Machines - multinational computer technology corporation).
- Quality of Reviews: The combination of AI and blockchain technology both ensures that reviews are public and transparent, while eliminating spam and malicious reviews. The use of blockchain technology on the Ethereum platform makes it impossible for reviews to be deleted or changed.
- Compensation mechanism: For useful reviews that have passed strict censorship conditions, they will be rewarded appropriately. This encourages users to actively rate and bring value to the community.
- Automatic filtering mechanisms all use machines and technology to detect fake posts, spam, and malicious content.
- Fair system: Another highlight of the project is using the Project and Smart Contract features to have a fair and unbiased evaluation system for reviews.
- Quality feedback for organizations and businesses: Giving accurate assessments of product and service quality not only helps new users have a basis to evaluate options, but also helps businesses improve quality. products from real users.
