Demystifying NFTs: Understanding the Digital Art Revolution

Create a comprehensive yet accessible 2000-word article explaining NFTs (Non-Fungible Tokens) to readers with limited technical knowledge. The article should cover: 1) A clear explanation of what NFTs are using simple analogies, 2) The underlying blockchain technology explained in layman's terms, 3) The distinction between NFTs and cryptocurrencies, 4) The various applications beyond digital art (music, gaming, real estate, etc.), 5) Step-by-step guide on how to create, buy and sell NFTs, 6) Environmental concerns and solutions, 7) The future potential and limitations of NFT technology. Include relevant examples of notable NFT sales and projects. The tone should be educational but conversational, avoiding unnecessary jargon while still being technically accurate.
