Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
Ethereum is a public blockchain-based platform that enables the development of decentralized applications (dApps) and smart contracts. It provides a decentralized virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes.
Ethereum also provides a cryptocurrency token called “ether”, which can be transferred between accounts and used to compensate participant nodes for computations performed. “Gas”, an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.
The native cryptocurrency of the Ethereum network is called ether. It is used to pay for transaction fees and computational services on the Ethereum network.
Ether is also used as a unit of account for other cryptocurrencies built on top of the Ethereum blockchain, such as ERC20 tokens.
The mainnet is the original and most important network for Ethereum. It is where the majority of users and developers interact with the Ethereum blockchain.
The mainnet is also where ether, the native cryptocurrency of Ethereum, is mined and traded.
