Spell Token Crypto, Web3 vs Web 3.0, Web 3.0 Apps and More

The term Web 3.0 is often used interchangeably with Web 3.0 technologies, such as blockchain, AI, and the Internet Computer. Crypto tokens such as Spell Token are considered Web 3.0 tokens, and there are many websites and applications that are built on Web 3.0 technology.
