Cardano's metadata feature enables users to attach additional data or information to transactions, tokens, or smart contracts on the Cardano blockchain. Metadata can include text, images, links, or any other type of structured or unstructured data, providing context, transparency, and richness to blockchain interactions. Metadata can be used for various purposes, including asset labeling, identity verification, content attribution, and regulatory compliance, enhancing the functionality, usability, and extensibility of the Cardano ecosystem.
