The present invention relates to a system for providing a subscription service for artwork and a method for providing the same. More specifically, the present invention relates to a system for providing a subscription service for artwork and a method for providing the same. More specifically, the copyright to the artwork is secured by digitally processing the artwork and minting it with an NFT (Non-Fungible Token) based on blockchain technology. It relates to a system and method of providing an artwork subscription service that not only enables safe transactions but also provides a subscription service that allows multiple subscribers to display artwork desired by them for a certain period of time.

The art market is a market where artworks are traded, and like other markets, suppliers, consumers, and distribution structures can be considered.

In some cases, artists hold personal exhibitions and sell works, but in the modern art market, works are generally traded through distributors. The distribution network is divided into a primary market, where works are purchased directly from the artist, and a secondary market, where collected works are resold.

Recently, as interest in art and culture has increased, the number of people who want to install works of art as an interior effect in their homes, restaurants, and offices is increasing.

In addition, as the Internet becomes part of daily life and online transactions become more active, ordinary people who like art can easily access and purchase works of art.

However, the price of works of art varies depending on the artist, and in the case of famous artists, the prices are higher, making it difficult for ordinary people who simply like works of art to realistically purchase them.

Accordingly, the number of companies that rent out works of art is increasing, and the number of joint purchasing cases in which multiple people purchase one work of art to rent it is also increasing.

Accordingly, in order to rent a work of art, as described in Publication Patent No. 10-2011-0009401 (publication date: January 28, 2011), certification of each supplier is performed in connection with an accredited institution, and the above certification is carried out.
