Non-fungible tokens (NFT)
NFTs are tokens that we can use to represent ownership of unique items. They let us tokenise things like art, collectibles, even real estate. They can only have one official owner at a time and they’re secured by the Ethereum blockchain – no one can modify the record of ownership or copy/paste a new NFT into existence.
NFT stands for non-fungible token. Non-fungible is an economic term that you could use to describe things like your furniture, a song file, or your computer. These things are not interchangeable for other items because they have unique properties.
Fungible items, on the other hand, can be exchanged because their value defines them rather than their unique properties. For example, ETH or dollars are fungible because 1 ETH / $1 USD is exchangeable for another 1 ETH / $1 USD.
To help you get a sense of how vague and complex a term “the metaverse” can be, here’s an exercise: Mentally replace the phrase “the metaverse” in a sentence with “cyberspace.” Ninety percent of the time, the meaning won’t substantially change. That’s because the term doesn’t really refer to any one specific type of technology, but rather a broad (and often speculative) shift in how we interact with technology. And it’s entirely possible that the term itself will eventually become just as antiquated, even as the specific technology it once described becomes commonplace.
Broadly speaking, the technologies companies refer to when they talk about “the metaverse” can include virtual reality—characterized by persistent virtual worlds that continue to exist even when you’re not playing—as well as augmented reality that combines aspects of the digital and physical worlds. However, it doesn’t require that those spaces be exclusively accessed via VR or AR. Virtual worlds—such as aspects of Fortnite that can be accessed through PCs, game consoles, and even phones—have started referring to themselves as “the metaverse.”
Many companies that have hopped on board the metaverse bandwagon also envision some sort of new digital economy, where users can create, buy, and sell goods. In the more idealistic visions of the metaverse, it’s interoperable, allowing you to take virtual items like clothes or cars from one platform to another, though this is harder than it sounds. While some advocates claim new technologies like NFTs can enable portable digital assets, this simply isn’t true, and bringing items from one video game or virtual world to another is an enormously complex task that no one company can solve.
