ICON Republic is the “hub”, of sorts, for all the various communities on the ICON network. C-Reps are responsible for making and managing this connection. All of the above is powered by ICON’s “Nexus” multi-channel blockchain, which is itself based on loopchain. Loopchain uses a Loop Fault Tolerance (LFT) consensus algorithm, which is very similar to a DPoS system, where C-Reps are “delegates” for their own communities on the network.
