What is Ethereum?

The programmable blockchain that powers smart contracts and DeFi.

Ethereum is a programmable blockchain launched in 2015. Its native asset ETH pays for computation on a global network that runs smart contracts — the foundation of DeFi, stablecoins and most on-chain applications.

Launched
July 2015 by Vitalik Buterin & co-founders
Consensus
Proof-of-Stake since The Merge (2022)
Block time
~12 seconds
Ecosystem
Thousands of dApps, L2 rollups and ERC-20 tokens

Smart contracts

A smart contract is code that lives on the Ethereum blockchain and runs exactly as written. Once deployed, no single party can quietly change it.

This lets developers issue tokens, run marketplaces and coordinate treasuries without a trusted intermediary.

Gas and fees

Every operation consumes gas, priced in gwei (a tiny fraction of ETH). Fees rise when the network is busy and fall when it's quiet.

Layer-2 rollups like Arbitrum, Optimism and Base bundle transactions off-chain and post proofs to Ethereum, reducing fees by orders of magnitude.

Proof-of-Stake

Since The Merge, Ethereum secures itself with validators who stake ETH instead of miners burning electricity.

This cut Ethereum's energy consumption by more than 99.9% and introduced native yield for stakers.

ERC-20 tokens

Most tokens you'll encounter — USDC, USDT, DAI, thousands of governance tokens — are ERC-20 contracts on Ethereum.

This shared standard is why any Ethereum wallet can hold any ERC-20 without custom integration.

Buying ETH on Nexone

Search for ETH in Nexone, place an order and settle in seconds. Withdrawals support Ethereum mainnet and popular L2 networks.

Fees, spreads and network costs are displayed before you confirm.

Risks

Smart contracts can contain bugs. ETH price is volatile. L2 networks and bridges introduce their own risk surface.

Only interact with contracts you have researched, and read the Nexone Risk Disclosure before trading.

Frequently asked questions

What is the difference between Ethereum and ETH?
Ethereum is the network. ETH is the native asset used to pay for computation on that network.
What is gas?
Gas is the unit that measures computational effort on Ethereum. Fees equal gas used × gas price.
Can I stake ETH on Nexone?
Nexone offers staking on supported assets subject to jurisdiction. See our Earn product page for current terms.
What is a layer-2?
A layer-2 is a separate network that inherits Ethereum's security while processing transactions more cheaply and quickly.
Are ERC-20 tokens safe?
The standard is safe; individual token contracts vary widely. Research each token before buying.
Does ETH have a maximum supply?
There is no hard cap, but ETH issuance is offset by base-fee burning, which can make it deflationary during high activity.
