What is Repair Miners (Filecoin)?

Repair miners are a proposed (as of June 6th, 2020) type of mining node within the Filecoin network that is presently in development. Repair miners, once enabled, will be able to facilitate self healing of the Filecoin protocol. At this time, the network is fully functional without the full implementation of repair miners and other types of miners that will be added in the future.
