What is Ethereum?

Ethereum is a decentralised network whose cryptocurrency is called Ether (ETH). Where Bitcoin focuses on being digital money, Ethereum was designed to run programs called smart contracts — code that executes automatically when conditions are met.

Smart contracts and apps

Smart contracts let developers build decentralised applications (dApps) for things like trading, lending, and digital collectibles. Ether is used to pay the network fees needed to run these operations.

Things to keep in mind

  • Ether’s price is volatile, like other crypto.
  • Network fees (“gas”) can rise when the network is busy.
  • Smart-contract apps can contain bugs or be targeted by scammers.
