Too Long; Didn't Read
NFTs (non-fungible tokens) - a new technology to represent digital assets - are now becoming more and more popular with many applications. They are reliable because of their immutability which means they cannot be changed or altered once minted on a blockchain. A new standard - ERC-1155 has been issued to define Dynamic NFT which can be changed due to what is written in the smart contract. NFT is now mostly used in Gaming and in-game items are usually designed to be upgraded while static (traditional) NFT tokens do not allow changes to be made.
