Blockchain refers to a digital ledger in which transaction details occurring between users are shared and stored among network members.

Transaction details that occur between users over a certain period of time are confirmed through consensus of more than half of the users, and the confirmed transaction details are bundled into one block and stored in the blockchain.

In order to change the transaction details included in a block connected to the blockchain, the consensus of more than half of the users must be obtained again for the block and all blocks connected after the block, so data stored in the blockchain cannot be forged or altered in practice. impossible.

Since it is impossible to arbitrarily change the transaction details stored in the blockchain, the reliability of data stored in the blockchain can be considered to be very high.

Therefore, recently, research has been actively conducted to safely store transaction details using blockchain in industrial fields that deal with transactions between users, such as Internet commerce and financial services.

Meanwhile, blockchain systems generally manage assets in the form of tokens created through smart contracts, and tokens are fungible tokens that can be exchanged with other tokens of the same type and each token It can be classified as a Non-Fungible Token (NFT), which has a unique ID and cannot be exchanged with other tokens.

In this way, since non-fungible tokens have the uniqueness of not being exchangeable with other tokens, they can be used as a means of safely guaranteeing ownership of specific assets, and recently, various products seeking to trade various products using non-fungible tokens have been developed. Attempts are being made.

An example of this is gift certificates for small business stores, but unlike gift certificates issued by large corporations, they are not easy to sell or use to consumers due to limitations in coverage, and because they are not easy to use, companies turn a blind eye to them, making them difficult to commercialize and not easy to use. Not only does it happen that the expiration date expires, but there is no value left after use, so it has no value as information after use.
