Ethereum (ETH) is an open-source, decentralized blockchain platform featuring smart contract functionality. It operates using its native cryptocurrency, Ether (ETH), and serves as a foundational technology for decentralized applications (DApps). Often regarded as "Bitcoin 2.0," Ethereum distinguishes itself through its advanced blockchain capabilities, enabling programmable agreements and a wide array of use cases beyond digital currency.
Key Features of Ethereum
- Smart Contracts: Self-executing contracts with terms written into code, enabling trustless transactions.
- Ethereum Virtual Machine (EVM): A runtime environment for smart contracts, ensuring compatibility across the network.
- Decentralized Finance (DeFi): Powers lending, borrowing, and trading without intermediaries.
- NFTs & Gaming: Facilitates ownership verification and in-game asset trading via non-fungible tokens (NFTs).
How Smart Contracts Differ from Bitcoin’s Blockchain
| Feature | Ethereum Smart Contracts | Bitcoin Blockchain |
|---|---|---|
| Functionality | Executes complex, programmable agreements | Processes simple transactions |
| Flexibility | Supports Turing-complete computations | Limited scripting language |
| Use Cases | DeFi, NFTs, DApps | Peer-to-peer payments |
Ethereum in DeFi: Top Applications
Decentralized Exchanges (DEXs):
- Uniswap: Pioneered automated market maker (AMM) systems, eliminating order books.
Lending Protocols:
- MakerDAO: Issues DAI stablecoin via collateralized debt positions (CDPs).
NFT Marketplaces:
- Platforms like OpenSea enable digital art and collectible trading.
Stablecoins:
- USDC and DAI maintain pegs to fiat currencies for stable transactions.

FAQ: Ethereum Essentials
Q: How does Ethereum’s proof-of-stake (PoS) differ from Bitcoin’s proof-of-work (PoW)?
A: PoS validators stake ETH to secure the network, consuming ~99% less energy than PoW mining.
Q: What’s the role of ETH in gas fees?
A: Gas fees (paid in ETH) compensate validators for processing transactions and smart contracts.
Q: Can Ethereum handle enterprise-scale applications?
A: Yes—enterprises use private Ethereum forks (e.g., Quorum) for supply chain and finance solutions.
