ERC-20 Fungible Token Standard

Welcome to the world of blockchain tokens! Beyond cryptocurrencies like Ether, blockchains host many other digital assets.

These assets, often called 'tokens', can represent anything from digital currency to ownership of real-world items, or even voting rights in a decentralized organization.

A key concept for tokens is fungibility. What does it mean?

• Fungible: Each unit is identical and interchangeable with another. Like a dollar bill – one $1 bill is the same as any other $1 bill.
• Non-Fungible: Each unit is unique and cannot be replaced by another. Like a piece of art or a specific house.

ERC-20 tokens are fungible, meaning every token is equal to every other token of the same type.
