Ether (ETH) is the native cryptocurrency of the Ethereum blockchain, serving as the "fuel" that powers network operations like smart contract execution and transaction processing. Whether you're minting an NFT or securing a DeFi loan, ETH is essential for paying gas fees—the cost of using Ethereum's decentralized infrastructure.
Ether 101: Understanding Ethereum’s Native Token
Ethereum is a decentralized platform enabling peer-to-peer value and data exchange without intermediaries. Its functionality relies on smart contracts—self-executing code that automates agreements when conditions are met. To maintain fairness and efficiency, Ethereum charges fees in ETH for transaction processing.
Key Differences Between Ether and Bitcoin
| Feature | Ether (ETH) | Bitcoin (BTC) |
|--------------|--------------------------------------|-----------------------------------|
| Primary Use | Smart contracts, dApps | Digital currency (P2P payments) |
| Consensus | Proof-of-Stake (PoS) | Proof-of-Work (PoW) |
| Flexibility| Supports programmable logic | Limited scripting capabilities |
Smart Contracts Explained
Smart contracts eliminate intermediaries by embedding terms directly into code. For example, a DeFi loan platform might automatically release funds when collateral is deposited—all governed by ETH-powered transactions.
How Ether (ETH) Works
ETH facilitates all Ethereum network activities:
- Transaction Fees: Paid as "gas" (denominated in gwei = 0.000000001 ETH).
- Miners/Validators: Earn ETH for securing the network.
- Spam Prevention: High gas fees deter malicious actors.

FAQ
Q: How do I buy ETH?
A: Purchase ETH on exchanges like OKX. Complete KYC, link a payment method, and trade.
Q: Why are gas fees volatile?
A: Fees fluctuate with network demand. Users can set gas limits to control costs.
Q: Is ETH inflationary?
A: Post-EIP-1559, some ETH is burned during transactions, reducing supply over time.
