Metadata
Data Layer, Token Property
Metadata is information attached to a digital asset or token that describes its characteristics, ownership, provenance, or other attributes. In the context of blockchain and NFTs, metadata provides the details that make each asset uniqueÔÇösuch as an imageÔÇÖs title, creator, description, file link, or traits for collectibles. Metadata can be stored directly on-chain or referenced by a URL or IPFS hash for larger files and complex data.
Use Case: When an NFT is minted on Ethereum or XRPL, its metadata defines its artwork, description, creator, and ownership historyÔÇöenabling marketplaces and wallets to display rich content and verify authenticity.
Key Concepts:
- NFT Standards ÔÇö Define how metadata is structured and accessed for unique digital assets.
- Token Standard ÔÇö Protocols may mandate metadata formats (e.g., ERC-721, ERC-1155, XLS-20).
- Fungibility ÔÇö Metadata is what separates non-fungible tokens (NFTs) from fungible assets.
- Interoperability ÔÇö Standardized metadata allows assets to function across marketplaces and apps.
Summary: Metadata brings meaning and utility to digital assets, making NFTs unique, verifiable, and valuable in the Web3 ecosystem. Proper standards and structure ensure assets are discoverable, tradable, and recognized everywhere.
