Since some time, the keyword “Blockchain” has become a trend. Blockchain is a forgery management technology based on distributed computing technology, and it prevents forgery by allowing no one to modify it and view results through a chain-type distributed data storage method created based on P2P.

When this distributed data storage environment is referred to as a “block,” a blockchain refers to a collection formed through countless connections of blocks. Cryptocurrency such as Bitcoin prevented forgery by applying blockchain technology and gained its own trust.

NFT stands for ‘non-fungible token’ and is a data unit stored in the blockchain. It can be seen as a token that proves the ownership of digital assets using blockchain technology. Currently, it is widely used in the form of proving ownership of various content files such as pictures and videos.

In 2021, the NFT created a so-called global boom. As the Corona crisis shows signs of prolonged, the public has found a new investment destination. The NFT had the right conditions. It was related to cryptocurrency but also connected to contents such as pictures and videos, giving a sophisticated feeling.

There were even cases in which ‘profile-type NFT’ used as SNS profiles, ‘art-type NFT’ in which photos, pictures, and videos were NFTed, and characters in the metaverse world or games were sold as NFTs.
