Soulbound tokens are essentially NFTs (or non-fungible tokens) bound to a soul. These tokens are linked to the holder and contain all of the user’s information. This can be medical data, credentials required for employment and other crucial information. This helps verify the information with no doubt whatsoever. However, unlike NFTs, soulbound tokens hold no monetary value and cannot be traded like NFTs, on say NFT gaming marketplaces, for obvious reasons.
