Mainstream

Mainstream is a decentralised file hosting platform for presentations. It can be used to rank speakers and authors, find the most influential people in your space, even attribute and get some feedback from people around the world.

Mainstream is not owned by anyone. It is fully decentralised. You can even run your own node on top on the Filecoin network with your own organization or you can run your own node and access to the public network of presentations.
