Ethereum basics, from absolutely zero

Ethereum is the network, ETH is its native asset, and smart contracts are programs on that network. Start with those three ideas before learning how to approve a transaction or use an application.

Three connected learning blocks carry a book, an Ether symbol, and a gear.

Learn the network before the interface

Start with the Ethereum overview. Read ETH vs Ethereum to distinguish the network from its asset, then learn how smart contracts enforce rules. None of these steps requires buying ETH or connecting a wallet.

Build the idea in three small steps

Network, asset, then program

Ethereum is the network. ETH is its native asset. A smart contract is a program on that network. Read the overview first, separate the two names next, and then explore what a contract can do. You do not need a wallet to learn these ideas.

  • First question: What does the network keep track of?
  • Next question: Which actions need ETH?
  • Then ask: Which rules does the program enforce?

Ethereum, explained without the sales pitch

Learn what Ethereum is, how ETH and smart contracts fit into the network, and how reading a balance differs from changing shared state.

ETH vs Ethereum: the name is doing two jobs

Learn the difference between Ethereum and ETH, why network fees use ETH, and how native ETH differs from token representations shown in a wallet.

A smart contract is a program. That’s the starting point.

Learn how Ethereum smart contracts apply rules, how reading data differs from changing it, and why code, audits, and a polished app do not guarantee safety.
