A blockchain token is a unit of value created on a blockchain. It represents a variety of assets or utilities and can serve different purposes depending on its design and function.Tokens can be classified mainly into two categories: utility tokens and security tokens. Utility tokens are used to access specific features or services within a platform. For example, they can be used to pay for transaction fees or access premium content. Security tokens, on the other hand, represent ownership in an asset, such as shares in a company or real estate. They are often regulated to protect investors.Tokens are often created through a process called an Initial Coin Offering (ICO), where projects raise funds by selling a set number of tokens to early investors. They are built on existing blockchain platforms, like Ethereum, which allows for easy trading and transfer among users.In essence, blockchain tokens serve as a flexible means to facilitate transactions, represent value, and create new economic models within various digital systems.
