Non-Fungible Token (NFT): Definition, Methods, and Examples

The term NFT is familiar to many today, as these tokens have penetrated many areas of our lives. But what does this acronym stand for?

NFT (non-fungible token) is a unique digital asset secured in a blockchain. Unlike fungible objects such as dollar bills, gold, or Bitcoin, each NFT is one of a kind and cannot be exchanged for another identical one. No two NFTs are the same.

Essentially, NFTs are the digital equivalent of a unique painting, passport, or collectible item.

Each NFT contains unique identifiers and metadata that distinguish it from other tokens. This data cannot be forged, deleted, or reproduced exactly.

NFTs are created through smart contracts — software codes on the blockchain that automatically execute the terms of the transaction between the token creator and the buyer. In this process, the blockchain acts as an independent intermediary, a decentralized and secure database that stores information about the ownership, origin, and history of each NFT.

In essence, an NFT is not just a token, but an entire digital object with encrypted information. It contains both blockchain data and additional metadata: a media file, description, Content ID, and structure in JSON format. Thanks to the combination of these parameters — a unique description, smart contract address, content ID, creator data, and transaction chain — it is impossible to fake or clone an NFT.

Let's look at a practical example:

What you see now is just a visual copy, a regular image saved with the right mouse button for example. The actual NFT associated with this image is not the image itself, but a digital record on the blockchain that contains all the information about this asset: a unique token identifier, smart contract address, metadata, and a link to the original media file.It is this record, not the image, that confirms the ownership and authenticity of a particular NFT.

Description of NFT Bored Ape Yacht Club #2:NFT number #2 from the Bored Ape Yacht Club collection is one of a series of unique digital avatars created as part of a limited edition. Each token in this collection has its own set of characteristics — facial expression, clothing, background, accessories, and other elements that shape its unique appearance and market value. All these parameters are encrypted in the blockchain and available for verification by any user.

It is important to understand that NFTs are not just images of monkeys or any other pictures. They can exist in a wide variety of formats: audio, video, digital collectibles, social media posts, virtual objects in metaverses (such as land plots), and even unique documents or game items.

The main feature of NFTs is their uniqueness and verified ownership rights recorded on the blockchain.

Why are NFTs necessary?

To better understand the purpose of NFTs, they can be divided into two broad categories, depending on where and how they are used: within the blockchain ecosystem or as proof of ownership of real objects.

This category includes tokens whose value and function are directly dependent on blockchain projects. Such NFTs often serve as passes, collateral, rewards, or status indicators within a community.

They can:

1. Provide access to private clubs and events,

2. Serve as proof of achievement or participation in a project,

3. Be used as collateral in DeFi applications,

4. Provide special rights and bonuses to owners.

Examples of collection NFTs

1. Avatars: Bored Ape Yacht Club, Meebits, Bulls on the Block, Cool Cats NFT, CLONE X,

2. Gaming NFTs: Axie Infinity, CryptoKitties, STEPN,

3. Virtual lands: Decentraland, The Sandbox,

4. Blockchain data and achievements: Project Galaxy.

One example of a blockchain NFT is the token from WOO Network, which can be obtained by completing a few simple steps on the decentralized platform WOOFi. Owners of such NFTs can expect various bonuses, gifts, or rewards in the future. You can obtain the token and familiarize yourself with the terms of participation on the Project Galaxy platform.

On the other hand, there are NFTs that are not tied to the functionality of blockchain projects. Such tokens act as digital proof of ownership of unique objects or data.

Tokenization is the process of converting rights to an asset into digital form by creating a token on the blockchain that secures ownership and ensures verifiability.Examples of such NFTs:

1. Digital artworks, images, and videos

2. Music tracks and albums

3. Unique clothing and accessories

4. Collectible sports team cards

5. Autographs of famous personalities

6. Precious metals and stones

Thus, NFTs can serve as both a tool for participating in the digital ecosystem and a way to officially confirm ownership of a unique physical or digital object.

Advantages of NFTs

Using NFTs opens up a whole range of possibilities and has several key advantages:

1. Uniqueness and authenticity. Each NFT is a one-of-a-kind digital object. This uniqueness makes tokens particularly valuable and sought after.

2. Transparent origin. NFTs. are recorded on the blockchain, which allows you to track ownership history and verify authenticity. As a result, each token has a verifiable chain of owners and a proven creation history.

3. Flexibility of formats. NFTs can represent a wide variety of digital assets: paintings, music, videos, tweets, game items, event tickets, and much more.

4. New monetization opportunities. Content creators can sell unique digital objects directly, generating revenue and creating new revenue models.5. Accessibility and trading. NFTs are easy to buy, sell, or exchange on specialized marketplaces. Any user can access digital artworks or unique items.

6. Fractional ownership. Some NFTs allow ownership of an asset, such as a work of art, real estate, or valuable items, to be divided, creating opportunities for joint investment.

7. Games and virtual worlds. NFTs are used in gaming ecosystems and metaverses. Players can own, exchange, and sell unique items or virtual real estate, creating new gaming and social scenarios.

8. Collecting. NFTs open up a new way of collecting digital objects, allowing people to own unique, non-counterfeit assets.

Important: The NFT space continues to evolve rapidly, and new use cases and benefits of tokens will change as technology advances and legislation evolves.

What can NFTs be used for?

NFTs are used in a wide variety of areas, opening up new opportunities for owners and creators of digital content. Here are some key examples:

1. Music. NFTs allow you to secure ownership of musical works, create new ways to monetize them, and provide artists with direct income from the sale of unique tracks or albums.

2. Video. Tokens can provide ownership rights to video content, such as videos on YouTube, TikTok, and other platforms, giving creators additional control and income.

3. Gaming. In the gaming industry, NFTs are used for unique in-game items—weapons, armor, accessories—that players can buy, sell, or trade with each other.

4. Collectibles. NFTs make it possible to own unique collectibles such as sports cards, digital images, stamps, and other rare items.

5. Virtual real estate. NFTs can represent ownership rights to virtual land or objects in metaverses and online games, creating fully-fledged digital ecosystems.

6. Social media. NFTs allow you to secure ownership of content on social media — tweets, posts, or unique posts — opening up new ways to engage with your audience.

7. Event tickets. Tokens can be used to issue tickets for concerts, sporting events, and other events, simplifying control and preventing counterfeiting.

8. Digital identification. NFTs can serve as digital IDs, be used in voting systems, for education certification, and for ownership of Web3 domains.

Example of innovation: The Unstoppable Domains platform uses NFTs to create Web3 domains, giving owners full ownership and control over their digital identity.

NFTs continue to evolve, and with the advent of new technologies, the scope of token applications will expand, opening up even more opportunities for monetization and creativity.

In conclusion

NFTs could become an important tool for digital identification thanks to their uniqueness and blockchain technology.

1. Property rights. NFTs can act as digital certificates confirming various credentials—educational degrees, professional licenses, membership tokens, and other rights. By linking such credentials to a user's decentralized digital identity, NFTs provide verifiability, transparency, and protection against tampering or forgery.

2. Security. Built on blockchain, NFTs use cryptographic algorithms and decentralized consensus mechanisms. This makes NFT-based digital identifiers reliable and secure against hacking, fraud, and unauthorized access.

3. Flexibility. NFTs allow users to interact with various platforms and decentralized applications (dApps) in the Web3 ecosystem. This simplifies digital identity management, as a single NFT can be used across multiple services without the need to create separate accounts for each application.

4. Independence. NFTs give owners complete control over their digital assets, including their digital identity. Users decide for themselves when, to whom, and how to grant access to their account data, which increases privacy and reduces dependence on centralized services.

Thus, NFTs create a secure, flexible, and self-managed way to manage digital identity in the Web3 world.Sign up and get access to free (for now) 0 to educated investor crypto education crash course.  Telegram | Discord | Twitter (X) | Medium | Instagram
