What is the ethereum network, explained plainly

A clear reply to "What is the ethereum network?" starts with two older coins that casino cashiers often list beside Bitcoin, Ethereum and Litecoin, which do quite different jobs. Ethereum runs programs and carries tokens, while Litecoin mostly moves value from one address to another. Knowing how each network charges its fees and what its addresses look like keeps a transfer on the right chain, where a mistake may cost the whole amount. Nothing here is a reason to buy either coin.

The Ethereum network measures the work behind each transaction in units called gas. Ethereum gas fees are paid in ETH, and the total depends on how much gas an action uses and on the price per unit at that moment, which climbs when the network is congested. A plain transfer needs less gas than a call to a complex contract. Wallets show an estimated fee before anything is confirmed, and on a busy day that fee can exceed a small transfer. A transaction that runs out of gas fails and still pays for the gas it used up.

An Ethereum wallet is an app or device that holds the keys to an account on the chain. The ETH and tokens stay recorded on the network itself; the wallet shows them and signs transfers. A new wallet displays its seed words once, and those belong on paper, away from the phone. An ETH wallet address starts with 0x followed by forty hexadecimal characters. Several compatible chains use exactly the same format, so a 0x address alone does not reveal which network a transfer will travel on. The network name has to match at both ends.

Asked about this

What is Litecoin used for?

Litecoin is an older coin built on the Bitcoin design with faster blocks, used mainly for payments rather than smart contracts.

What is Ethereum, and what is ETH?

Ethereum is a public blockchain that runs smart contracts and carries tokens; ETH, or ether, is its native coin and pays for every action on it.

What does a Litecoin wallet address start with?

Litecoin addresses commonly start with L, M or ltc1, which tells them apart from Bitcoin addresses.

Why does a wallet need ETH to send USDT on Ethereum?

Gas on Ethereum is paid in ETH even when the coin being sent is a token, so a wallet holding only USDT cannot move it.
