The term metadata describes data which gives information about other types of data. Metadata functions as a secondary element which provides essential information about sources and times and structural elements and contextual aspects. The digital environment uses metadata to enable systems which handle data to achieve better operational outcomes through improved data management and tracking and data understanding.
A blockchain system stores metadata in its transactions and blocks through usage of timestamps and wallet addresses and transaction fees and block numbers. The public can examine all the metadata of blockchains because the system allows open access to blockchain data.
NFTs and tokenized assets require metadata for their operational functions. The metadata for NFTs describes digital items by showing their name, description, image link and traits. Marketplaces use this metadata to display NFTs which users can use to confirm the contents of a token. Metadata hosting problems create situations where changes to metadata lead to uncertainty regarding permanent data status and ownership rights.
