NFT metadata is a crucial element of NFT mining. It is the essence of an NFT. The metadata gets manifested as a JSON document which describes the essential properties of the NFTs. These include:
– The name of the NFT
– Its description
– Links to images and other digital assets
What purpose does the metadata serve?
Metadata helps display NFTs in an easily understandable format for the market players. It renders compatibility to the NFT ecosystem, including wallets and tools. This compatibility gets executed through the JSON format.

The metadata storage options
Three options take on the use-case requirements, of which the NFT size and cost make for primary parameters.
This storage option is ideal for metadata less than 100 bytes. The data can get stored directly in the field when minting the NFT. However, this field is immutable, that is, unalterable. Another aspect is that multimedia cannot get stored here.
2. Hedera File Service
A distributed storage service, this one is apt for storing multimedia. It is ideal for file sizes between 100 bytes and 30kb.
Another distributed storage service, Filecoin, is ideal for storing high-resolution images appropriate for art and other rich multimedia.
