# From NFT 1.0 to NFT 2.0: A Review of the Evolution of Non-Fungible Tokens
## 4 From NFT 1.0 to NFT 2.0
### NFT 2.0: Applications  
NFT 2.0 has the potential to be used in a wide range of applications, from art and music to sports and real estate. Some of the potential applications of NFT 2.0 include:  
* **Music.** NFT 2.0 can be used to create unique digital music assets that can be traded and owned by fans. Music NFTs are considered certificates of ownership for identifying owners of a piece of musical work. Artists can sell the music NFT to anyone while retaining the rights to make any changes to its content. Furthermore, the artist can have complete discretion over how the buyer uses the piece of music.
* **Gaming.** NFTs can have a significant impact on gaming, and in particular, on play-to-earn (P2E) games. Game developers can create customised NFTs that represent in-game items or achievements, allowing players to own and trade unique digital assets that are tied to the game's ecosystem. NFT 2.0 has the potential to transform the gaming industry by providing new ways for players to own and transfer in-game assets, verifying authenticity and rarity, enabling interoperability, and providing tangible representations of rewards and achievements.
* **Sports.** The sports industry is benefiting much from this evolution. NFT 2.0 can be used to create unique digital collectibles that represent ownership of sports memorabilia. They also can be used to create digital tickets and fan experiences, or to represent athletes and their sponsships, allowing for new forms of revenue and endorsement deals. Finally, NFT 2.0 can be used to represent digital assets used in fantasy sports and gaming, such as virtual teams and players that mirror the performance of the athlete.  
* **Metaverse.** NFT 2.0 can be used to represent ownership of real estate assets, allowing for the fractional ownership of high-value properties [65]. This opens up new opportunities for investment and ownership of real estate assets. For instance, an NFT representing a property should be dynamic enough to reflect the maintenance history, age, market value, and much more in real time.
* **Token gating.** Token gating is a way of restricting access to something and using NFTs as a way to unlock access. NFT 2.0 can be used in the practice of \"token gating\", which involves requiring users to hold a specific NFT to access certain content or services. This concept can be used to create exclusive communities or provide access to premium content. Thanks to their dynamic nature, NFTs 2.0 can be used to grant access only once to an event, and even reveal additional properties [64].
* **Art.** NFT 2.0 has several applications in the art industry, as it allows for the creation of unique and verifiable digital assets that can represent artwork and provide new ways for artists to moneties their work [66]. NFT 2.0 can be used to represent fractional ownership of artwork, allowing multiple owners to own a portion of a piece of art. This can create new opportunities for investment in art and provide a new revenue stream for artists. Furthermore, NFT 2.0 can be used to represent licenses or royalties for artwork, allowing artists to receive ongoing revenue for their work. This can also create new opportunities for secondary markets and provide a new way for artists to moneties their work.
* **Healthcare.** Healthcare is another field that could benefit widely from digital twin NFTs 2.0. For instance, in an organ donation scenario, NFT 2.0 can be used to keep track of the donor, and the organ. Additionally, IoT devices can be employed to periodically monitor the condition of the organ (i.e., temperature, humidity) while it is transported. Lastly, NFT 2.0 has been employed to trace refurbished medical devices: each part of the machine is modelled as a separate NFT that keeps track of its condition, and the medical devices are composable and dynamic NFTs [11].
