NFT is short for Non-Fungible Token. Non-fungible means “unique”. A dollar or bitcoin for example are fungible, because all dollars are the same in value and other features. A non-fungible token is a digital representation of something of value, there is only one of it, and it can not be copied.
RFT stands for Rainforest Token and it represents a piece of real rainforest land. Each RFT is unique, and represents a specific piece of land, at a certain location. Furthermore, the RFT is serving as validation of your positive impact and grants you access to different services from Fund the Planet.
