We will also look at future trends and innovations that are shaping the future of this rapidly growing technology.

What is NFT?

A Non-Fungible Token is a unique digital asset whose authenticity and ownership is confirmed on the blockchain. Unlike interchangeable tokens such as Bitcoin or Ethereum, each NFT has unique properties that make it impossible to replace with another token.

NFT’s uniqueness comes from the use of advanced cryptographic mechanisms that ensure the uniqueness of each token. The system uses hash functions and digital signatures to generate unique identifiers for each asset.

NFT can be compared to a digital certificate of ownership, which is impossible to forge thanks to the use of blockchain technology. Every transaction and change of ownership is permanently recorded in a distributed ledger, ensuring full transparency and traceability of a given token.

It is worth noting that NFT does not store the digital asset itself (e.g., an image or video), but only points to it through a unique identifier. This distinction is crucial to understanding both the capabilities and limitations of this technology.

How does NFT work?

The foundation of NFT’s operation is a smart contract (smart contract) stored in the blockchain. Smart contracts contain a set of rules and conditions that automatically execute when certain criteria are met. In the case of NFT, they determine, among other things, the rules for creating, transferring and managing the token.

The process of creating an NFT, called “minting,” involves storing a unique token on the blockchain along with metadata describing the asset it represents. The metadata can include information about the creator, creation date, copyright or links to digital assets.

Each NFT transaction is verified by a network of blockchain nodes, ensuring the security and irreversibility of operations. This system eliminates the need for a trusted third party in the process of transferring ownership of digital assets.

An integral part of the NFT ecosystem are trading platforms (marketplaces) that allow users to buy, sell and exchange tokens. These platforms integrate with cryptocurrency wallets, providing a secure way to store and manage tokens.

NFT smart contracts can also include additional functionality, such as automatic calculation of royalties for creators with each subsequent token sale or the ability to “burn” (burn) a token, i.e. permanently remove it from circulation.

How is NFT different from cryptocurrencies?

The main difference between NFTs and cryptocurrencies lies in their fungibility. Cryptocurrencies are fungible tokens – one Bitcoin can be replaced by another Bitcoin of the same value. NFTs, on the other hand, are unique and cannot be exchanged one for one.

Cryptocurrencies mainly serve as a means of payment or storage of value. NFTs, on the other hand, represent ownership of specific digital or physical assets, making them more similar to property deeds than to currency.

The technology behind NFT makes it possible to track the provenance and history of each token, which is especially important for digital art or collectibles. In the case of cryptocurrencies, the history of individual units is irrelevant to their value.

The pricing mechanisms of NFTs work differently from those of cryptocurrencies. The value of NFTs is determined by the uniqueness, rarity and demand for a specific asset, while the value of cryptocurrencies is mainly driven by market mechanisms of supply and demand for the entire asset class.

In terms of security, NFTs require more complex protection mechanisms due to the uniqueness of each token. The loss of an NFT is irreversible and it cannot be replaced with an identical copy, unlike cryptocurrencies.

What are the standards for NFT tokens?

ERC-721 was the first NFT standard introduced on the Ethereum network and remains one of the most widely used. This standard defines the basic functions and interfaces necessary to create and manage non-exchangeable tokens.

The newer ERC-1155 standard has introduced the ability to create both exchangeable and non-exchangeable tokens within a single smart contract. This solution significantly increases efficiency and reduces transaction costs when creating tokens in bulk.

The NFT standards also specify how token metadata is stored and accessed. Metadata can be stored directly on the blockchain or in decentralized storage systems such as IPFS.

The development of NFT standards is an ongoing process, with the blockchain community actively working on new solutions that address current limitations and introduce new functionality. Examples include proposals for standards that enable NFT fractionalization or the implementation of more advanced rights management mechanisms.

Interoperability between different NFT standards is a significant challenge for ecosystem development. Platform and application developers must take into account the differences between standards when designing their solutions.

What are the technologies behind NFT?

Blockchain is the fundamental technology that makes NFT possible. Most NFT tokens are created on the Ethereum platform, but other blockchains, such as Solana, Cardano and Polkadot, also offer support for NFT.

The InterPlanetary File System (IPFS) protocol plays a key role in storing NFT-related metadata and resources. It is a decentralized file storage system that ensures data persistence and availability independent of a single server.

Smart contracts, usually written in the Solidity language for the Ethereum platform, contain NFT business logic. They define rules for creating, transferring and interacting with tokens, and implement standards such as ERC-721 or ERC-1155.

Cryptographic technologies, including hash functions and digital signatures, ensure the security and authenticity of NFT. Advanced blockchain consensus mechanisms, such as Proof of Stake, are also used to guarantee the integrity of the entire system.

The development of Layer 2 technologies and scaling solutions, such as Polygon and Optimism, is crucial to the future of NFT. These technologies allow for significant reductions in transaction costs and increased system throughput.

What are the applications of NFT?

Digital art was the first and remains one of the most popular applications of NFT. Artists use the technology to tokenize their works, allowing them to reach a global audience and receive royalties from subsequent sales. The system has revolutionized the digital art market, allowing artists to monetize their works directly without intermediaries. In addition, smart contracts ensure that royalties are automatically calculated and paid on each subsequent sale, a significant innovation compared to the traditional art market.

In the video game industry, NFTs enable the creation of unique in-game items that players can trade on the open market. The technology introduces the concept of real-world ownership of virtual items and allows them to be transferred between different games.
