It is a smart contract framework that allows building apps that enforce its contracts. Underneath it uses to proof of stake to provide security, create opportunity for passive income and allow resolution of disputes - similar to Aragon Court. In conjunction there's a app (Universe-Ui) that uses the framework to create a trustless ecommerce marketplace. This was born from a place of experiencing unsatisfactory outcomes engaging with people and companies under terms that allowed them to not exactly fulfil what was expected and that were also too costly to dispute. It is a work in progress, nothing can be tested currently and code is partially open source.
This sub repo (Universe-Ui) is partially open sourced; https://github.com/evergreen-trading-systems/universe-ui and has a limited demo; https://universe-ui.netlify.app/
Being completely open source is part of the roadmap and some sub repos have a date but it's not today.
