Cryptocurrency tokens are units of value that are issued by a project, often utilizing an existing blockchain infrastructure. Unlike cryptocurrencies, like Bitcoin and Ethereum, which operate independently and have their own blockchains, tokens often rely on pre-existing frameworks, such as the Ethereum blockchain, for their creation and transactions. These tokens can represent a myriad of functions, such as granting the holder the right to participate in a network, representing a stake in a project, or even functioning as currency within a specific ecosystem.
