不可替代代幣和區塊鏈技術的概念是我們這個時代的熱門話題。 它們在世界各地廣泛使用，並已被納入經濟和金融實踐中。 近年來，區塊鏈技術發生了令人難以置信的變化。 多個行業採用了區塊鏈解決方案，並培養了它們可以承載的標準和功能數量的快速增長。 此技術擴張趨勢不斷加大，勢必對圖書出版行業產生影響。 目前有一些解決方案，利用可替代、不可替代和半可替代的代幣方式。 本研究論文概述了該領域最大和最受歡迎的作品，介紹了它們使用的方法，並提供了另選項的解決方案，即 Dapp（去中心化應用程序）的以作者為中心的安全系統。

Non-fungible tokens and blockchain technology are becoming increasingly common in recent years, widely used worldwide and included in many financial practices. With the rapid development of blockchain technology, many industries have adopted blockchain solutions, and the number of standards and functionality this technology can carry has increased greatly.
It is likely to also impact the book publishing industry since it provides clear advantages for self-publishing authors, such as anonymity, immutability and transparency.
However, the security of print media is still a serious concern. This study presents two solutions for limiting unauthorized access to these assets- smart contracts, and non-fungible tokens. This paper presents an overview of the largest and most popular methods in the field and provides alternative solutions that can be used as the basis for a more secure author-focused system with decentralized application.
