What is Ethereum?

Ethereum is a global, open-source platform for decentralized applications. On Ethereum, you can write code that controls digital value, runs exactly as programmed, and is accessible anywhere in the world.

What are Ethereum smart contracts?

A “smart contract” is simply a piece of code that is running on Ethereum. It’s called a “contract” because code that runs on Ethereum can control valuable things like ETH or other digital assets.

What is Proof of Work and Mining?

Ethereum currently uses a system called “Proof of Work”. This allows the Ethereum network to agree on the state of all information recorded on the Ethereum blockchain, and prevents certain kinds of economic attacks.

What are Ethereum Clients and Nodes?

The Ethereum network is made up of many nodes, each of which runs compatible client software. There are two clients that are used by a majority of nodes: Geth (written in Go) and Parity (written in Rust).
