Ethereum is a blockchain that was developed to support scripting and the creation of decentralized applications and
'smart contracts' through its virtual machine (EVM).
Ethereum's native token, Ether (ETH) is a cryptocurrency used to pay for the processing power of the EVM in order to run
smart contracts or other Dapps, in what is called 'gas'.
Smart contracts have been used on Ethereum for a variety of purposes, from issuing ICO tokens to creating entire
decentralized autonomous organizations (DAOs).
