We are currently working on Curyo. The main idea is to create a new rating system for the age of AI, since we think we need better/new quality signals for the web. We are generally interested in getting more feedback on what a good rating system should be.
FYI: We previously submitted a link to the website to invite people to test it, but it was immediately flagged as "dead". I'm not sure why, but the project is completely open source, and there's no money involved or anything like that. It uses a public ledger, but this is because we thought a trustless ledger would make sense for a new rating system (because of the transparency). We are happy to change this if people prefer a database, because it's more user-friendly.
