Brave Software has developed a cryptocurrency enabled web browser that is designed to change the ad-based revenue models of the internet. The Brave browser is powered by an Ethereum-based token, and revolves around a blockchain-based digital advertising platform. It has the potential to change the existing online media dynamic and better meet the needs of internet users, publishers and advertisers. Users benefit from a faster web experience, publishers can increase their revenue with less cluttered ads, and advertisers will benefit from more transparency and more effective ads. At the core of Brave's platform is the Basic Attention Token (BAT), that enables micropayments between users and publishers. They hope to establish a new revenue model for the web that isn't based on intrusive ads, but on user attention.

Decent is developing a decentralized content distribution platform with a native blockchain. It will allow anyone to buy, sell, or share content without intermediaries. Decent runs on a Proof of Custody blockchain, that is powered by its native coin, Decent (DCT). DCT is used to view and publish content. Content creators can upload media and choose a price that users can pay to download. The file is then uploaded and encrypted to the network. Publishers (miners) host the content, and users can download it. Decent also has a reputation system that is designed to facilitate the distribution of relevant content to users.
