Understand Non-Fungible Tokens
NFTs, like cryptocurrencies, are transactions stored on the blockchain. However, what sets it apart from cryptocurrencies is its non-fungible feature. One bitcoin will always be equal to another bitcoin, we can exchange them for each other, and they all have the same value. It's the same with dollars: it's called the fungible property of money. The creators of NFT wanted to do exactly the opposite: a transaction stored on the blockchain that is non-fungible, therefore completely unique. The idea is to be able to use it as a certificate of authenticity associated with a digital or physical object.
The first ideas for certificates of authenticity linked to the blockchain appeared in 2014. But it was not until 2017 that the first artistic projects based on NFTs were born. CryptoPunk, a collection of pixelated character designs and huge inspiration for DarkMeta was sold through this.
The NFTs within DarkMeta have all been attached to unique tokens that make each one different from the next no matter how similar they look.
Each token indeed carries unique metadata. In the case of the DarkMeta game, the tokens represent different game features. There isn't any duplicate tokens. This itself boosts the idea of scarcity. This combined with other features of the gameplay makes some NFTs more valuable than others. To make it even more interesting, players are able to sell their NFTs for DMT tokens.
