What is Dynamic NFT?

The NBA series of NFTs belong to this type. Unlike the general fixed NFTs, the NFTs of this series will change their appearance over time. Each NFT represents a player from the NBA's 16 playoff teams and is linked to real-time data on that player and their respective teams.

NFTs will change visually based on how players and teams perform during the 2022 NBA playoffs, with visual changes including backgrounds, accessories and emojis. The association showcases NFTs from emerging genres known as dynamic NFTs that change over time.

【Static NFTs & Dynamic NFTs】
Once a static NFT is registered on the blockchain, it will not be changed. Generally speaking, it will receive a token ID at the time of minting, and metaverse data, both of which are permanent.

Dynamic NFTs are customizable tokens, which can be synchronized with external data on the premise of maintaining ID, and the data of NFTs will also be updated according to preset conditions.

【Update of Metaverse Data】
The data of an NFT can contain names, descriptions, features, images, videos or other related file links, while the parameters of dynamic NFTs can change with external data.

NFT developers use the writing function of smart contracts to code to create dynamic NFTs, and the data of NFTs will be updated independently according to the rules defined in the contracts.

In this way, developers can link any external data, both on-chain and off-chain, with NFTs, such as the association NFTs mentioned above, and the stadium data that measures player achievement (smart contract definition) is Synchronous.

When an achievement is fulfilled, the corresponding NFT changes visually, in short, the smart contract decides whether the data changes according to predetermined conditions.

【Dynamic NFT use case】
The scope of application of dynamic NFT is very wide, and the following three are listed:

• Community systems <br class="smart">Take the Pearproof app as an example, which allows social media creators to mint NFTs on their posts. It shows how dynamic NFTs can be used to create closed communities and reward systems based on the performance of underlying NFTs.
  
  Pearproof NFTs gain value when posts get more interactions, so relevant data such as comments, shares, and likes will affect dynamic NFTs. If the post becomes popular, the NFTs will upgrade. Fans who own these NFTs will receive different rewards based on their NFTs level.

• Progressive blockchain games <br class="smart">Character development is one of the core of video games, as the character's level in the game increases, it can acquire new abilities, so the NFT assets in the game can also be Dynamically, for example, if a well-defined action in a smart contract is triggered, it may improve the performance of an object.
  
  The collection game Aavegotchi uses the concept of dynamic NFT to create a farming game. In each round of the game, players must cultivate and improve virtual pets with different rarities. Rewards only increase when players truly care about their pets, all thanks to the dynamic nature of NFTs.

• Fundraising <br class="smart">Another high-profile use case is a short film project for a renewable resource company. Three short films were minted as dynamic NFTs to raise funds for the reforestation funding project. For every frame of NFT sold, a new frame appears until the entire film is complete, making the fundraising process more engaging.

The possibilities for dynamic NFT applications are endless, as developers connect data to NFTs in unexpected new ways, adding to the growing list of NFT utilities.
