Welcome to the FCR wiki!

What is FCR?

FCR is a client to participate in an FCR network that can be viewed as a form of the filecoin secondary retrieval market. If you are not familiar with the concept of retrieval market, visit retrieval market official website.

There are three fundemental roles in an FCR network:

  1. Retrieval provider: Node that provides content to the network for paid retrieval.

  2. Payment provider: Node that provides proxy payment to a given recipient for surcharge.

  3. Retreival client: Node that retrieves a content from a retrieval provider with direct payment or indirect payment through payment providers.

Each FCR node can be one or a mixed of multiple of these roles.
