Project Alexandria use IPFS, and FileCoin as a token layer enabling cryptographic proof of sharing.
An open-source distributed library for sharing and preserving art, history and culture. Imagine a platform like Youtube, Soundcloud, or Netflix - without any of the costly server or bandwidth overhead.
Only the publisher has the power to remove her/his content from the library - blocktech.com 
This allows users to earn money by storing and distributing content for publishers. Users access content through a library of meta-data stored in the Florincoin blockchain, which can be accessed through custom front-ends or a web gateway.
Devon Read, Head of Project Management at Alexandria said: “Our approach is to give artists a direct relationship with their audiences by putting them in complete control of how much their content costs, what front ends they wish to use, and even whether they’d like to offer a promoters cut to those that help share their art.”
