What is Ethereum?

A shared computer that anyone can use and anyone can check.

LET’S PICTURE IT

Think of a public game board. Everyone can check the rules, and no single player gets to secretly rewrite the score.

A node receives a proposed transaction or block-related message. Receipt is not the same as accepting its claims.

More than a payment notebook

A blockchain can record payments. Ethereum also runs programs called smart contracts. They can track ownership, exchange tokens, or apply rules for a shared project. Ethereum keeps both a history and a current state: who owns what and what each program remembers.

The same rules for everyone

Many nodes check the same transactions. If a program says a ticket belongs to Maya, the network checks each allowed change to that record. This public verification can reduce reliance on a single operator. It does not guarantee that the program was designed well or that its website is honest.

Where ETH fits

Ether (ETH) is Ethereum’s native asset. It pays for computation through gas fees and helps secure the network through staking. A token built using a contract is different from ETH, even if your wallet displays them together.

What to learn next

Start with a wallet and a pretend transaction. You do not need to buy anything to learn here. Our experiments use local examples, so you can explore how Ethereum works before deciding whether to use a real network.
