A gamified educational platform from Stellar Development Foundation (SDF) lets people earn non-fungible tokens (NFTs) by learning about blockchain technology in general and Stellar ($XLM) Network<\/a> in particular.<\/p>\n Stellar is \u201can open-source network for currencies and payments\u201d, and it \u201cmakes it possible to create, send and trade digital representations of all forms of money\u2014dollars, pesos, bitcoin, pretty much anything.\u201d Stellar \u201crelies on blockchain to keep the network in sync, but the end-user experience is more like cash\u2014Stellar is much faster, cheaper, and more energy-efficient than typical blockchain-based systems.\u201d <\/p>\n Stellar network, which was launched in 2014, has \u201ca native digital currency, the lumen, that\u2019s required in small amounts for initializing accounts and making transactions.\u201d <\/p>\n Here is one use case for Stellar:<\/p>\n \u201cYou can create a digital representation of a U.S. dollar\u2014on Stellar you\u2019d call this a \u201cdollar token\u201d\u2014and you can tell the world that whenever someone deposits a traditional dollar with you, you\u2019ll issue them one of your new tokens. When someone brings that \u201cdollar token\u201d\u00a0back\u00a0to you, you promise to redeem it in turn for one of the regular dollars in that deposit account. <\/em><\/p>\n \u201cEssentially, you set up a 1:1 relationship between your digital token and a traditional dollar. Every one of your tokens out in the world is backed by an equivalent deposit. So while people hold the tokens, they can treat them just like traditional money, because they know that they\u2019re exchangeable for traditional money in the end.<\/em>\u201c<\/p>\n The original Stellar Quest platform, which was created by SDF ecosystem evangelist Tyler van der Hoeven<\/a> and launched in October 2020, was aimed at developers and it featured live challenges (such as creating and funding a Stellar account). For completing each challenge, you would get awarded a badge and some $XLM tokens.<\/p>\n
