Ethereum is a programmable blockchain. ETH is its native asset. This page explains what the network does, how it differs from Bitcoin, and where to check a live ETH price without treating a quote as advice.
What Ethereum is
Ethereum went live in 2015 as a blockchain that can run programs, not only send payments. Those programs are called smart contracts. A smart contract is code stored on the network that runs the same way on every node when its conditions are met. Tokens, stablecoins, lending pools, and NFT collections are contracts of that kind.
ETH (ether) is the asset that pays for computation on the network and that validators stake to secure it. The official documentation is at ethereum.org. The whitepaper proposed a general-purpose blockchain. The network has shipped upgrades since launch, including the switch from mining to proof of stake in September 2022.
If you already follow Bitcoin, start with our Bitcoin price guide for the quote habit, then come back here for the difference in design.
How it differs from Bitcoin
Bitcoin and Ethereum optimize for different jobs. Bitcoin's design is a peer-to-peer electronic cash system with deliberately limited scripting. Ethereum's design is a platform that can run almost any program a user pays gas for.
| Area | Bitcoin | Ethereum |
|---|---|---|
| Primary purpose | Peer-to-peer digital currency | Platform for apps and digital assets |
| Consensus | Proof of work | Proof of stake (since The Merge, Sept 2022) |
| Supply | Fixed cap of 21 million | No fixed cap; a portion of fees is burned |
| Block time | About 10 minutes | About 12 seconds |
| Smart contracts | Limited scripting | Core feature (Solidity, Vyper) |
| Energy use | High (mining) | Low after the proof-of-stake switch |
Neither network is always cheaper. Bitcoin fees compete for block space by transaction size. Ethereum fees pay for computation through gas. A simple ETH transfer is cheap on a quiet day and expensive when the network is busy. Layer-2 networks (rollups such as Base or Arbitrum) bundle transactions and post data back to Ethereum, which is where most low-fee activity now lives.
Smart contracts and gas
A smart contract is a program parked at an address. Anyone can deploy one. By default, nobody can delete it afterwards. That is useful for shared rules and dangerous if the code has a bug. A contract that holds funds will hold them until its own rules release them, or until a flaw is exploited.
Gas is the unit that prices computation. Every step of a contract costs gas. The fee is the gas used times the gas price. Ethereum's fee system has a base fee that is burned and an optional tip for the validator. You set a limit. If the limit is too low, the transaction fails and you still pay for the work done.
Do not send a contract interaction from a page you do not trust. A wallet should show you the contract address and the function before you sign. If the page asks for a seed phrase, close it. A real wallet never needs your seed phrase in a browser form.
Proof of stake
Since The Merge on 15 September 2022, Ethereum has used proof of stake instead of mining. Validators lock ETH as a deposit for the chance to propose and attest to blocks. Dishonest behavior can cost them that deposit. The switch cut the network's energy use by roughly 99%, according to ethereum.org. It did not change how ETH is used to pay fees.
Staking requires a minimum of 32 ETH for a full validator, or a smaller amount through a staking service or a liquid-staking contract. Those are different risk profiles. A service holds the keys or the contract holds the rules. Read the service's own page before you send funds. This article does not recommend any of them.
Upgrades continue. Named upgrades have shipped most years since 2019. A network upgrade does not change your ETH balance. Node operators update their software. Your wallet does not need a new seed phrase because of an upgrade.
Where to check the price
There is no single official ETH price. The number you see is the last trade on a venue or an average of several. Open a live aggregator or the exchange you trust and read the pair (usually ETH/USD), the timestamp, and the source line. The same rules apply as on our XRP price page: a screenshot is not the market.
If you are judging a finance site the way you would judge a software vendor, separate the marketing line from the data page. Our FundfireInsight brand check is the same habit applied to a lookalike name.
What this page will not do
- It will not print a dollar price. Use a live page and read the time.
- It will not say whether to buy, sell, or stake. That is advice.
- It will not rank wallets, staking services, or layer-2 networks.
- It will not treat a social post as the market or as a contract audit.
The takeaway
Ethereum is a programmable blockchain. ETH pays for computation and secures the network through staking. It differs from Bitcoin in purpose, consensus, supply design, and block time. There is no single official price. Open a live page, read the pair and the timestamp, and do not treat a number in an article or a screenshot as the market.
