The full name of NFT is Non-Fungible Token, which is indivisible, irreplaceable, and unique.

On the blockchain, digital cryptocurrency is divided into two categories: native currency and token. The former, such as BTC, ETH, etc., have their own main chain and use transactions on the chain to maintain account data; tokens are attached to the existing blockchain and use smart contracts to record the account, such as attached to Ethereum The token issued from above. Tokens can be divided into two types: homogenization and non-homogeneity.

Homogeneous tokens, namely FT (Fungible Token), can replace each other and can be close to infinitely split tokens. For example, there is essentially no difference between a BTC in your hand and a BTC in my hand. This is homogenization and homogenization of coins.

Non-homogeneous tokens, namely NFTs, are unique and indivisible tokens, such as encrypted cats and tokenized digital tickets. It is equivalent to a dollar with a number, and there will be no two dollars with the same number.

Therefore, compared to FT, the key innovation of NFT is to provide a way to mark the ownership of native digital assets (that is, assets that exist in the digital world or originate in the digital world), and this ownership can exist in centralized services Or outside the centralized library. The ownership of the NFT does not prevent others from inspecting it or reading it. NFT does not capture the information and hide it, it just captures the information and discovers the relationship and value of the information with all other information on the chain.

At the same time, due to its non-homogeneous and inseparable characteristics, NFT can anchor the concept of commodities in the real world. Simply understood, it is a digital asset issued on the blockchain. This asset can be a game item. , Digital artwork, tickets, etc., and are unique and non-copyable. Because NFT has natural collection attributes and is easy to trade, crypto artists can use NFT to create unique digital artworks.
