Project Description

We have built a chrome extension to democratise data sharing and wrench power back from big tech. In today’s digital economy, protecting the rights and privacy of the people should not come at the cost of the internet as we know it today. Kleo allows people to choose what they share and with whom. When a user lands on one of our partner sites, we pre-fill relevant data from the user’s browsing history on the Kleo pop-up. Users are given single-click toggles to share these attributes if they want to in the same way they would manage cookie preferences today. ****The simplicity of Kleo is that we don’t look to change user behaviour while continuing to provide rich and contextual user data.

The main incentive here is to offer an extremely personalised experience to each visitor based on the information they’ve consented to share with platforms, and also to receive Kleo tokens in exchange for all this.

How it's Made

The idea is that to allow users to connect with their personal data on different websites while preserving their privacy. The ideal customer profile is loaded up by the websites where they decide how they should bucket their customers based on who they are. Users collect brownie points in form of APE tokens. The questions are nothing but circuits, the proof is generated and shared with organisation which then can be verified on chain thus user privacy is maintained.

Now there could be two things here - users start going to different websites to farm the tokens which means we need a way to stop that. That's where RLNs come in.

Also in order to make sure intent is not violated we are using UMA optimistic oracle.
