# NFT

## WAAT is an NFT

WAAT Games uses NFT technology because it represents the future of both art and gaming.\
This technology enables **traceability**, **uniqueness**, and **authentication** of digital files through the **blockchain**.

Blockchain technology allows for the secure storage of **unique digital assets**.\
Our first part, TittyMatrix, is already available on the **Cardano blockchain**.\
**Stay tuned for the upcoming launches.**

​

## What is an NFT?

**NFT** stands for **Non-Fungible Token,** a unique digital asset stored on a blockchain. Unlike cryptocurrencies such as Bitcoin or ADA, which are interchangeable (fungible), each NFT is **one-of-a-kind**, with its own identity and properties.

NFTs are powered by **smart contracts,** self-executing lines of code that live on the blockchain. Once deployed, these contracts are **immutable** and **decentralized**, meaning no one can alter them or tamper with the rules they define. This ensures the **security, transparency**, and **authenticity** of ownership.

Each NFT contains or links to **metadata**, which includes details such as:

* The creator’s identity
* The creation date
* A description or title
* A link to the associated digital file (artwork, music, video, etc.)

Most of this metadata is stored **off-chain**, while the ownership, transaction history, and essential properties are stored **on-chain**.

| Concept                      | Explanation                                                                                          |
| ---------------------------- | ---------------------------------------------------------------------------------------------------- |
| **NFT**                      | Non-Fungible Token, a unique digital asset stored on a blockchain                                    |
| **Fungible vs Non-Fungible** | Fungible = interchangeable (e.g. 1 ADA = 1 ADA) / Non-fungible = unique (e.g. NFT #1055 ≠ NFT #1056) |
| **Smart Contract**           | Self-executing code that defines how the NFT works                                                   |
| **Blockchain**               | A decentralized, public ledger where the NFT lives (e.g. Cardano, Ethereum)                          |
| **Metadata**                 | Info about the NFT (creator, title, traits, file link, etc.)                                         |
| **On-Chain vs Off-Chain**    | Ownership is stored on-chain / media files and metadata are often off-chain                          |
| **Utility**                  | Some NFTs offer more than visuals: access, games, rewards, lore…                                     |
