This reputation and ranking framework is aiming to increase transparency online through blockchain communities. Polish startup Userfeeds is developing a content-ranking system for newsfeeds that is inspired by Google Pagerank and Liquid Democracy. They are working on algorithms that would promote trustworthy news sources on the Internet, addressing the issue of fake news on media platforms with blockchain transparency.
Using cryptocurrency Ethereum, Userfeeds hopes to bring transparency and stronger verification processes to the provision of information online. Still in the proof of concept stage, their ranking framework would enable users to create block-chain based advertising networks similar to Google Adsense, decentralized social media destinations, decentralized voting systems and reputation currency schemes that would let users reward people for using cryptocurrencies.
