A digital currency that is rewarded to miners or validators on a blockchain in exchange for correctly validating network transactions.
Blockchain users must also pay a transaction fee (or miner fee) in the form of cryptocurrencies in order for their transaction to be included in the next block.
What is the difference between a cryptocurrency (or 'coin') and a token?
Although the terms 'cryptocurrency' and 'token' are often used interchangeably, there are some minor differences.
A token is a digital asset that is created and used within a Dapp or protocol that sits on top of a blockchain, while a cryptocurrency is the native currency of a blockchain that is rewarded to miners or validators for confirming transactions that occur on that blockchain. For example, ETH is the native currency of the Ethereum blockchain, while DAI, UNI or ENS are tokens launched on Ethereum using smart contracts.
