In a blockchain, multiple computers that act as servers (nodes) are widely distributed to form a single network, and data recording is made only for data that has passed verification of all nodes. Due to this structure, the block chain is difficult to hack, and once stored data is impossible to forge or falsify, it is highly reliable. This is the reason why NFTs, which were created based on this, boast excellent compatibility in areas where security and trust are important, such as proof of ownership or genuine product authentication.
