Revain: Building a Trustless, Consumer Review System on the Blockchain

Trustless.

This is kind of a weird word that is often used to describe one of the main benefits of cryptocurrencies. What it means is that the system is built so that trust is simply not a factor. You don’t have to trust it since there is no way to game it. There is no central bank, not governmental institution, no regulator, or anyone else who can step in a tweak the system for their or anyone else’s benefit. The system simply works, you can know it works, and you can know exactly how it works.

Trustless is also the wave of the future. So much of what we do is dependent on our needing to trust a third party – and often enough we have no way to know if that person is trustworthy. With the advent of cryptocurrencies and blockchains, it is now becoming possible to simply remove that element. And the extreme frontier for trustless systems would seem something we all rely on, and something we all know can be manipulated, hacked, or just downright unstrustable: online reviews.

Revain is a new blockchain-based review system that is seeking to solve some of the problems with firsthand reviews. Their system combines an internal token built on Ethereum that will be used to incentivize quality to reviews and penalize bad actors (on both the consumer and provider sides), an IBM AI system utilizing a neural network to vet all reviews for quality and veracity, and an immutable blockchain to record all reviews so that they can never be promoted, demoted, manipulated, removed or edited. Once a review has been authenticated, it will become part of the permanent record.
