The native cryptocurrency of the Ethereum network is Ether.
“Ethereum” and “Ether” are often used interchangeably to refer to
the cryptocurrency with the ticker symbol ETH. Technically speaking:
Ether (ETH) is a digital asset, and Ethereum is a blockchain
network.
The lifeblood of Ethereum is ETH. It is like the “digital petrol”
that fuels the entire network. ETH is a transactional token used to
facilitate operations within Ethereum’s ecosystem. If a user sends a
payment or interacts with an application on Ethereum, they have to
pay a small “gas” fee to the network, which is paid in ETH.
