Core Concepts

What are NFTs?

Non-Fungible Tokens are cryptographic tokens that represent unique digital or physical assets, with each token having distinct properties that make it non-interchangeable with other tokens.

NFT Characteristics:

• Uniqueness: Each token has distinct properties
• Indivisibility: Cannot be divided into smaller units
• Ownership Verification: Blockchain-verified ownership
• Programmability: Smart contract functionality
• Transferability: Can be bought, sold, and traded
• Interoperability: Work across different platforms

How NFTs Work

NFTs operate through smart contracts on blockchain networks, with metadata defining the token's properties and content references.

Technical Components:

• Smart Contracts: ERC-721, ERC-1155, and other standards
• Metadata: JSON files describing token properties
• Content Storage: IPFS, Arweave, or centralized storage
• Token ID: Unique identifier for each NFT
• Contract Address: Smart contract location on blockchain
• Ownership Records: Blockchain-based ownership history
• Royalty Mechanisms: Creator royalty distribution
