With so much talk about NFTs, we're tearing down the veil and looking back to the background to talk about the most important aspects of metadata
In our recent blog posts, we've been discussing NFTs' future and the potential of NFT tokens. We're here to explore the infamous online asset, providing all the information you require to be aware of how to store NFT metadata.
What is an NFT?
For many, NFTs are essentially PNGs or JPEGs that are pictures that are pixelated and don't really have much meaning. This isn't the reality. To say, "an NFT represents an intangible token. It's a digital asset based using blockchain technology. It proves that you own an item such as an image or video or gaming product. They are intriguing because they allow you to verify the ownership of various objects through the blockchain. You can purchase and trade NFTs to exchange cryptocurrency."
For more details to the description, "non-fungible" is a reference to a unique item. What is the difference between these cryptographic assets? They all have unique identification codes as well as metadata. In terms of metadata, let's move to the next section of this article.
What exactly is ERC721 token?
ERC721 is the standard token on Ethereum on which NFTs are based, which makes them unique and, as a result, noninterchangeable.
What exactly is NFT metadata?
In simple terms, NFT metadata is the properties or details that make up the digital asset. The details that create your NFT look and sound exactly how it should. The most frequently utilized metadata include:
Name of the file
file description
History of Transaction
Any information that the creator believes is essential to include
The most common misconception that we don't know about NFT metadata is they're distinct entities and are not identical to the NFT. Metadata is kept in a distinct location, which is essential to preserve the value of the NFT.
Before getting into the storing procedure, let's explore this concept more thoroughly. What happens when you store NFT metadata? It is the fact that the asset contains a link to the metadata that exists online. What else is there? Here is the point where things start to get fascinating. Data storage can occur in the chain or away from the chain.
Metadata on-chain
This kind of metadata is incorporated into the blockchain NFT as a whole, which means that it is possible that the NFT "information" also lives on the blockchain. Storing information on the chain poses some issues that could threaten its value NFT. As you are aware that links fade and hosting platforms do not exist forever, and if something happened to the blockchain it could affect it's possible that the NFT inherent value, as well as ownership, might be affected.
Off-chain metadata
How can you ensure security for your NFT metadata by providing that it's accessible at all times? Many people utilize cloud storage or servers. While these solutions are reasonably secure, given the potential of NFT investments They aren't bulletproof solutions. They're both hackable, and subject to issues. That's where an Interplanetary File System IPFS comes into.
What exactly is an Interplanetary File System (IPFS) service?
IPFS can be described as an open peer-to-peer network that stores metadata as well as shares them in an open file system. IPFS is connected to File coin, a peer-to-peer network that stores data with built-in financial incentives to ensure that files remain safe in the long run. It's not storage for data like you're used to. In this new system, businesses do not have ownership of the user's data. Instead, individuals retain the rights to their own data.
The system lets users save and retrieve content by relying on the "fingerprint" of the content (a cryptographic hash, also known as CID) which is distributed across a number of distinct storage companies. This leads to the following question How do you find out which storage services for files are the most trustworthy?
This is the reason Filecoin can provide the foundation to implement the credibility system as well as it provides a method to communicate with various storage providers. Consider a CID as an identifier that refers to the content. Here's an example of what a CID hash appears like:

If the storage company is shut down or, for any reason, is unavailable, you will be able to access the metadata.
Free NFT storage
To make the experience even more amazing, IPFS launched NFT storage which is a service for free that allows users to store up to 31GB of size for each upload.
IPFS Advantages
CID files cannot be altered and can not be modified by third-party organizations.
When data is retrieved from various sources and not from a central server content retrieval is speedier and more efficient
Creators can share their work at no cost
Data loads faster because it is faster
Only one version of every resource, which makes duplicates impossible and authentication much simpler.
There isn't a single cause of failure because IPFS content is stored at multiple locations in an open, peer-to-peer network that uses a distributed hash table (DHT)
Final thoughts
NFT metadata shouldn't be a last-minute thought, but instead an essential element for every NFT initiative or financial investment. Connecting to the metadata outside of the smart contract, it is enhancing the NFT architecture, reduces the cost of computation, and also ensures that the authenticity of the asset's data is kept on the blockchain, while the asset itself is kept off-chain
