How Do NFTs Work?

Understanding Blockchain Technology

At the core of NFTs lies blockchain technology, a decentralized and distributed ledger that records transactions across multiple computers. Unlike traditional databases managed by a central authority, blockchain offers a transparent and immutable record of transactions. Each block in the chain contains a list of transactions, and once a block is added, it cannot be altered without changing all subsequent blocks.

Key Features of Blockchain Technology:

• Decentralization: Eliminates the need for intermediaries by distributing data across a network.
• Transparency: Provides a transparent history of transactions, viewable by anyone on the network.
• Security: Ensures data integrity through cryptographic hashing and consensus mechanisms.

The Role of Smart Contracts

Smart contracts are self-executing contracts with the agreement directly written into code. They automatically enforce and execute the terms of a contract when predetermined conditions are met, eliminating the need for intermediaries.

Functionality of Smart Contracts in NFTs:

• Automation: Facilitates automated transactions, reducing the need for manual intervention.
• Trust: Creates trustless environments where parties can transact without knowing each other.
• Efficiency: Increases transaction speed and reduces costs by automating processes.

Token Standards: ERC-721 and Beyond

The majority of NFTs are built on Ethereum using the ERC-721 standard, which defines a unique, non-fungible token. ERC-721 ensures that each token is distinct, providing unique ownership records.

Other Token Standards:

• ERC-1155: Allows for both fungible and non-fungible tokens within a single contract, enhancing efficiency.
• Flow: Developed by Dapper Labs, this blockchain is optimized for high performance and scalability, commonly used in platforms like NBA Top Shot.

Minting NFTs

Minting is the process of creating a new NFT. It involves converting digital files (art, music, videos) into a cryptographic token recorded on the blockchain. This token represents ownership and can be transferred or sold.

Steps in Minting NFTs:

1. Create Digital Asset: Develop the digital file to be tokenized.
2. Select Marketplace: Choose a platform like OpenSea or Rarible.
3. Upload and Mint: Upload the file to the marketplace and initiate the minting process, setting terms for ownership and resale royalties.

The Difference Between Fungible and Non-Fungible Assets

Fungible Assets: Definition and Examples

Fungible assets are items that are identical in value and interchangeable. They can be divided into smaller parts, and each part retains the same value as another.

Examples of Fungible Assets:

• Currencies: US Dollar, Euro.
• Cryptocurrencies: Bitcoin, Ethereum.
• Commodities: Gold, oil.

Non-Fungible Assets: Definition and Examples

Non-fungible assets are unique and cannot be exchanged on a one-to-one basis. Each asset has distinct characteristics that determine its value.

Examples of Non-Fungible Assets:

• Real Estate: Each property has unique attributes like location and size.
• Collectibles: Rare trading cards, antiques.
• Digital Assets: NFTs representing art, music, or virtual land.

Comparative Analysis

Fungible Tokens:

• Interchangeable: Each unit is identical and can be swapped with another of the same type.
• Divisibility: Can be divided into smaller units without losing value.

Non-Fungible Tokens:

• Unique: Each token is distinct and represents a unique item.
• Indivisible: Cannot be divided without losing its essence or value.

Table Explanation:

• Definition: Fungible assets are those that can be replaced by another identical item; non-fungible assets are unique and not directly replaceable by another.
• Examples: Fungible assets include currencies and cryptocurrencies, while non-fungible assets include real estate, collectibles, and NFTs.
• Interchangeability: Fungible assets are interchangeable; non-fungible assets are unique.
• Divisibility: Fungible assets can be split into smaller parts without loss of value; non-fungible assets cannot.
• Value Determination: The value of fungible assets is the same across units; the value of non-fungible assets is unique to each.
• Ownership Records: Fungible assets typically do not require individual tracking; non-fungible assets have distinct ownership records.
• Transferability: Fungible assets can be easily transferred; non-fungible assets often involve more complex transfer conditions.
• Market Dynamics: Fungible assets generally have stable, liquid markets; non-fungible assets can have illiquid and volatile markets.
• Common Usage: Fungible assets are used in everyday transactions and as investments; non-fungible assets serve as proof of unique ownership and are often collected.
• Risk Profile: Fungible assets tend to have a lower risk profile; non-fungible assets can be more volatile.
• Technology Use: Fungible tokens use standards like ERC-20; non-fungible tokens use standards like ERC-721 and ERC-1155.

This table provides a concise comparison, making it easier to understand the fundamental differences between fungible and non-fungible assets.
