About link description

Decentraland (MANA) defines itself as a virtual reality platform powered by the Ethereum blockchain that allows users to create, experience, and monetize content and applications. In this virtual world, users purchase plots of land that they can later navigate, build upon, and monetize. Decentraland uses two tokens: MANA and LAND. MANA is an ERC20 token that must be burned to acquire non-fungible ERC721 LAND tokens.
