What is Ethereum? Programmable Money, Explained

Published May 16, 2026 · New-U Team · 7 min read

Short answer: Ethereum is a worldwide network that, besides moving its coin ETH, can run small programs called smart contracts. That is why dollar-pegged stablecoins and most of “web3” live there. This is general information, not financial advice.

If Bitcoin is digital gold, Ethereum is closer to a shared, programmable computer. It does everything Bitcoin does - send value peer-to-peer - and adds a layer where code, not a company, enforces the rules of an agreement.

ETH vs “Ethereum”

Ethereum is the network. ETH (ether) is its native coin. You can send ETH like any other crypto, and you also need a small amount of ETH to pay the network’s processing fee - called gas.

Gas fees, simply

Every action on Ethereum costs gas, paid in ETH. Think of it as postage: a busy network means higher postage, a quiet one means lower. Gas is why people sometimes time transactions for off-peak hours, and part of why faster, cheaper networks like Solana became popular for everyday payments.

Smart contracts and tokens

A smart contract is a program that runs exactly as written and can’t be quietly changed. The most relevant use for payments is tokens: Ethereum’s ERC-20 standard lets an issuer create a coin that lives on Ethereum. That is how USDC and USDT - dollar-pegged stablecoins - work. (Those same tokens also exist on other networks.)

Paying with ETH or an Ethereum stablecoin? Make sure your wallet is set to the Ethereum network and keep a little ETH spare for gas, even if you’re paying in USDC. Step-by-step: How to pay with crypto.

Trade-offs

Frequently Asked Questions

Ethereum vs ETH?
Ethereum is the network; ETH is its coin and pays gas fees.

What are gas fees?
The ETH fee to process a transaction; higher when the network is busy.

Why do stablecoins live on Ethereum?
Its ERC-20 token standard makes dollar-pegged coins like USDC/USDT easy to issue; they also exist on other chains.
