NFTs (Non-Fungible Tokens) are unique, digital, and non-interchangeable tokens, primarily based on the Ethereum blockchain. They have multiple applications and are constantly being developed for various purposes. This article delves into the concept of NFT metadata and its storage, either on-chain or off-chain.
On-chain transactions are secure, transparent, and decentralized, but they can be slow and expensive. Off-chain transactions, on the other hand, are faster and cheaper, but they lack transparency and can disrupt the process.
NFT metadata, which includes the NFT’s file name, description, and information, is stored separately on blocks to preserve its value and protect it from fraud. Metadata storage is critical as it determines the existence of a singular NFT or an entire collection.
On-chain metadata storage is secure but complex and requires high-level development skills. Off-chain metadata storage is easier and cheaper but can collapse if there are problems with the storage linked.
To enhance security, the Inter Planetary File System (IPFS) was developed. It’s a decentralized storage option in WEB3 and a multinode system that stores metadata off-chain. When an NFT needs to be viewed, the NFT requests to receive content. The IPFS finds the required file using a unique 24-character ID for each set of data.
In conclusion, NFTs and their metadata have their pros and cons, and developers must decide early on the best storage option. 💻🔗🔐🌐📊📁🔍
