What Is a Dynamic NFT and How Does It Change Over Time?

Non-fungible tokens (NFTs) have gained significant attention in recent years, revolutionizing the way we perceive and interact with digital assets. While static NFTs have been the norm, a new category of tokens called dynamic NFTs has emerged, introducing a whole new level of interactivity and functionality to the blockchain space.

Dynamic NFTs are unique digital assets that can change and evolve over time. Unlike their static counterparts, which represent fixed properties, dynamic NFTs are programmable and can respond to external inputs or conditions. This ability opens up a wide range of use cases and opportunities for personalization, interactivity, and value creation in the digital creator economy.

In this article, we will explore what dynamic NFTs are, how they can be changed, their applications in various industries, and the benefits they offer to artists and collectors. We will also highlight the differences between static NFTs and dynamic NFTs and provide examples of dynamic NFT projects that are pushing the boundaries of this evolving technology.

What Are Dynamic NFTs?

Dynamic NFTs are a sub-category of NFTs that possess the ability to change and evolve over time. Each dynamic NFT contains metadata that describes its characteristics, such as names, descriptions, and specific features. This metadata can be altered based on predefined conditions, allowing the NFT to adapt and respond to external factors.

Compared to static NFTs, which are typically created using the ERC-721 token standard, dynamic NFTs are designed using the ERC-1155 token standard. This token standard enables the semi-fungibility of dynamic NFTs, making them more versatile and adaptable.

The use of smart contracts plays a crucial role in the functionality of dynamic NFTs. Smart contracts are self-executing programs that are encoded within the NFT. They automate certain functions and enable interactions, such as changing the appearance or behavior of the NFT based on specific circumstances.

Characteristics of Dynamic NFTs

Dynamic NFTs possess several key characteristics that distinguish them from their static counterparts. These characteristics include:

Programmability: Dynamic NFTs are programmable, allowing creators to define rules for how the NFT should behave. This programmability enables automation, control, and the creation of new use cases and applications.
Interactivity: Dynamic NFTs offer a high level of interactivity, making them more engaging and interesting for collectors and audiences. The ability to change and evolve over time adds a layer of excitement and uniqueness to the NFT.
Versatility: Dynamic NFTs can be used in a wide range of services beyond digital art. They can be applied in gaming, social networks, identity management, and various other industries, opening up new possibilities for innovation and creativity.
Revenue Generation: Dynamic NFTs provide new revenue streams for artists. Creators can earn royalties on the ongoing use or interaction with their NFTs, creating a sustainable source of income in the digital economy.

The Role of Smart Contracts

Smart contracts are at the core of dynamic NFTs, enabling their programmability and functionality. These self-executing contracts are encoded within the NFT and automate specific functions and interactions.

Smart contracts define the rules and conditions for how a dynamic NFT can change and evolve. They can incorporate external data, such as real-time market prices, user behavior, or environmental data, to trigger updates in the NFT's metadata.

The use of smart contracts also ensures the secure and transparent execution of transactions involving dynamic NFTs. They define how the NFTs can be bought, sold, or traded, as well as how royalties should be distributed to the creators.

Overall, smart contracts provide the foundation for the dynamic nature of NFTs, allowing them to adapt and respond to external inputs and conditions.

How Can Dynamic NFTs Be Changed?

The process of changing a dynamic NFT involves several steps, including minting the NFT, obtaining data from oracles, evaluating the NFT based on the data, and updating its characteristics when necessary.

Minting Dynamic NFTs

The creation of a dynamic NFT starts with the minting process. A smart contract is used to mint the initial version of the NFT, which includes a set of metadata that describes its initial characteristics.

The smart contract defines the rules and conditions for how the NFT can change over time. These rules can be based on various factors, such as user behavior, external data sources, or specific events.

Oracles and Data Sources

Oracles play a crucial role in the modification of dynamic NFTs. Oracles are third-party services that provide external information from data sources, such as internet-of-things (IoT) data and web application programming interfaces (APIs).

The smart contract obtains data from these oracles to evaluate the NFT and determine if any changes should be made. The data obtained can include real-time market prices, weather conditions, user interactions, or any other relevant information.

Oracles provide a gateway for dynamic NFTs to interact with the real world and respond to changing conditions. They bring external data into the blockchain ecosystem, enabling dynamic NFTs to adapt and evolve based on this information.

Evaluating and Updating Dynamic NFTs

Once the smart contract has obtained the necessary data from oracles, it evaluates the current state of the dynamic NFT and determines if any changes should be made.

The evaluation process can involve various algorithms and rules that are predefined in the smart contract. For example, a dynamic NFT representing a gaming avatar could be evaluated based on the player's progress and updated to reflect the avatar's level, abilities, or appearance.

If the evaluation determines that changes are required, the smart contract updates the metadata of the dynamic NFT accordingly. The characteristics of the NFT, such as its name, description, or specific features, are modified to reflect the new state of the NFT.

This process ensures that dynamic NFTs can adapt and respond to external inputs or conditions, providing a more engaging and personalized experience for collectors and users.

Dynamic NFT Applications

Dynamic NFTs have a wide range of applications across various industries. Here are some of the key areas where dynamic NFTs are being utilized:

Identity

One potential application of dynamic NFTs is in identity management.
