What Is Ether (ETH): The Ultimate Guide
What Is Ether (ETH): The Ultimate Guide
Ether (ETH) is the native cryptocurrency of the Ethereum blockchain, a decentralized platform enabling smart contracts and decentralized applications (dApps). As the second-largest crypto by market cap, ETH fuels transactions and computational services on the network. This guide explores its mechanics, use cases, and risks.
Pain Points: Why ETH Adoption Faces Hurdles
Users often struggle with gas fee volatility and scalability bottlenecks. For instance, a 2023 DEX trade costing $50 in fees during peak congestion deters small investors. Layer-2 solutions like Optimistic Rollups aim to resolve this.
Technical Deep Dive: How ETH Works
Step 1: Consensus Mechanism
Ethereum shifted from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in 2022, reducing energy use by 99.95% (Cambridge Centre for Alternative Finance).
Step 2: Smart Contract Execution
ETH powers Ethereum Virtual Machine (EVM) operations, with fees calculated in gwei (10-9 ETH).
| Parameter | Layer-1 Ethereum | Polygon (Layer-2) |
|---|---|---|
| Security | High (Mainnet) | Moderate (Sidechain) |
| Cost | $1-$100/tx | $0.01-$0.10/tx |
| Use Case | High-value DeFi | Microtransactions |
Critical Risks and Mitigation
Smart contract vulnerabilities caused $3.8B losses in 2023 (Chainalysis). Always audit code via firms like OpenZeppelin. Phishing attacks target ETH wallets—use hardware wallets like Ledger.

FAQ
Q: Is Ether (ETH) the same as Ethereum?
A: No—Ethereum is the blockchain platform; Ether (ETH) is its native cryptocurrency.
Q: Can ETH be mined?
A: Not since 2022’s Merge. ETH now uses staking for validation.
Q: What is Ether (ETH) used for?
A: Paying transaction fees, staking, and as collateral in DeFi protocols.
