(NFA) stands for Non-fungible Acre, essentially an NFT. A Non-Fungible Token (NFT) is a unit of data stored on a digital ledger, called a blockchain, that certifies a digital asset to be unique and therefore not interchangeable.NFTs can be used to represent items such as art, property, and assets. In the case of LiquidAcre, our NFTs are an immutable digital representation of ownership in physical land.
