Web3 Introduction
Discover the fundamentals of Web 3.0, blockchain, and NFTs, and learn how to create and trade unique digital assets.
Understanding Blockchain, Web 3.0, and NFTs
Web 3.0 and the Metaverse represent the next stage of the internet and digital culture. A key technology enabling this shift is blockchain, which creates value for digital content creators like yourself. Let’s break down the basics of Web 3.0, blockchain, and NFTs so you can better navigate this evolving landscape.
Web 3.0: The Decentralized Evolution of the Internet
Web 1.0 was the early, static internet, where users could only read content without interacting.
Web 2.0 introduced interactivity, allowing users to engage with websites and contribute content (think social media).
Web 3.0 is the next phase, defined by decentralization, where online activities are not controlled by centralized entities like banks or tech companies, but rather by blockchains—networks where data is stored and verified without intermediaries.
Centralized vs. Decentralized Systems
In a centralized system, a middleman like a bank or online marketplace controls and secures your interactions. In contrast, decentralized systems, powered by blockchain technology, allow users to interact and transact directly, with security and data integrity maintained by the blockchain network itself, without the need for a third-party authority.
Blockchain
A blockchain is a decentralized digital ledger spread across multiple computers, ensuring that data is immutable and secure. It works by cross-verifying data across a network of computers, preventing tampering or fraud. The network itself ensures data integrity, with no single entity in control.
There are many different blockchains, each with unique features and trade-offs. Some popular examples include Ethereum, Ripple, and Polygon. We’ll focus on Ethereum and Polygon for their relevance to NFTs.
Fiat Money and Cryptocurrency
Fiat money refers to government-issued currencies like the US dollar. You’ll need fiat money to purchase cryptocurrency on an exchange.
Cryptocurrency is a form of digital currency that exists on a blockchain. It operates similarly to digital currencies used in video games (e.g., V-Bucks or Robux), but without central control. Cryptocurrencies like Bitcoin, Ethereum, and Polygon (POL) can be exchanged for real or digital goods.
Mining and Crypto Exchanges
Mining involves using computer hardware to maintain blockchain networks, with miners rewarded in cryptocurrency.
A Crypto Exchange is a platform like Coinbase or Binance where you can buy, sell, and trade cryptocurrencies by exchanging fiat money for digital currencies.
Wallets: Where You Store Digital Assets
A wallet is a secure place to store cryptocurrencies and digital assets. Examples include MetaMask, Ledger, and Exodus. Wallets can either be software-based (like MetaMask) or hardware-based (like Ledger), offering different levels of security. To interact with the blockchain and NFTs, you’ll need a wallet to store your crypto.
NFTs (Non-Fungible Tokens)
NFTs are unique digital assets that represent ownership of something—whether it’s digital artwork, music, or virtual real estate. Unlike cryptocurrencies, which are fungible (interchangeable), NFTs are one-of-a-kind, making them valuable in the same way a rare painting or collectible would be.
When you create and upload digital content as an NFT onto a blockchain, the process is called minting. Minting ensures that the NFT is authentic and can be traced back to its creator on the blockchain.
NFT Marketplaces
NFT Marketplaces, like OpenSea and Rarible, are platforms where you can buy, sell, and mint NFTs. Each marketplace has its own fee structures and advantages, so it’s wise to compare options. Most transactions incur gas fees, which are fees paid to compensate for the computing power needed to process blockchain transactions.
Gas Fees
Gas fees are transaction costs for using blockchain networks. The more a blockchain is used, the higher the gas fees tend to be. These fees can vary significantly depending on the time of day and network activity, ranging from under $1 on blockchains like Polygon to over $1,200 on Ethereum.
Bridging Blockchains
Some NFT Marketplaces support cross-blockchain transactions, meaning you can use different blockchains to mint and trade NFTs. Bridging is the process of transferring data between blockchains, which may incur additional gas fees.
Additional Key Terms
Tokens: Any digital asset on a blockchain, including cryptocurrencies and NFTs.
DAO (Decentralized Autonomous Organization): A collective of individuals collaborating to run decentralized systems without traditional corporate hierarchies.
Smart Contracts: Automated contracts programmed into the blockchain that execute when predefined conditions are met.
3D Asset NFTs are unique, non-fungible tokens representing digital 3D models or assets, often used in virtual worlds, games, or the Metaverse. These assets can be anything from a character or vehicle to a virtual building, providing creators with ownership rights and the ability to trade them on NFT marketplaces. In the context of Decentralverse AI, 3D Asset NFTs are a core part of creating immersive, interactive virtual environments.
Land NFTs represent virtual real estate within digital environments, particularly in blockchain-based virtual worlds like Decentralverse AI. These NFTs give owners exclusive rights to a specific plot of land, which can be customized with 3D assets and traded in the Metaverse. Land NFTs allow users to build, develop, and monetize virtual spaces, driving value in the emerging digital economy.
