NFTs, or Non-Fungible Tokens, have gained significant attention. But where is the data actually stored?
NFTs are unique digital assets stored on a blockchain. This allows their authenticity and ownership to be verified.
While the core NFT data resides on the blockchain, the actual media (image, video, etc.) is often stored elsewhere, with a link to it contained within the NFT. Methods like IPFS are used.
To find an NFT, you can use platforms like Mintable. Enter the Token ID in the search bar.
Block explorers, such as explorer.solana.com, allow you to search using the mint address.
You can also find NFTs using wallet addresses or transaction IDs.
Ultimately, NFTs are linked to blockchain, ensuring verifiable ownership.

The smart contract associated with the NFT also lives on the blockchain, defining its properties and functionalities.
This distributed ledger technology ensures transparency and immutability, making NFTs a revolutionary way to represent ownership of digital and physical assets.
NFT wallets are the best place to store your NFTs, providing a secure and convenient way to manage your digital collectibles.
Understanding the underlying storage mechanisms is crucial for appreciating the value and potential of NFTs in the evolving digital landscape.

While the blockchain records ownership and metadata, the actual file associated with the NFT (the image, music, video, etc.) often resides off-chain. This is due to the limitations of blockchain storage capacity and cost.
Instead of storing the entire file directly on the blockchain, the NFT’s smart contract contains a URI (Uniform Resource Identifier) that points to the location of the file. This URI could be a standard web address (URL) or, more commonly, an IPFS (InterPlanetary File System) hash.
IPFS is a decentralized storage network that allows for content-addressable storage. This means that the file is identified by its content, rather than its location. When the content changes, so does the IPFS hash, ensuring that the NFT always points to the correct version of the file.
Storing the file off-chain offers several advantages, including lower storage costs, faster transaction speeds, and the ability to store larger files. However, it also introduces the risk of link rot, where the URI becomes invalid and the file can no longer be accessed.
To mitigate this risk, some projects use decentralized storage solutions like Arweave, which offer permanent and immutable storage for digital assets.
Ultimately, understanding the distinction between the NFT’s metadata (stored on-chain) and the associated file (often stored off-chain) is crucial for evaluating the long-term viability and value of an NFT.
Regardless of the storage method, the blockchain acts as the source of truth for NFT ownership, providing a secure and transparent record of who owns which digital asset.
