The ICON cryptocurrency (or ICON coin) uses its ‘loopchain’ platform - called the Nexus - to connect multiple blockchains. This is done via the ICON Republic, which is the governing body for a group of independent blockchain communities.
These blockchain communities connect with the ICON Republic via their representatives, which are elected by the communities themselves.The blockchains can then exchange value between each other using ICON’s own decentralised exchange (DEX).
