What is Ethereum?
Ethereum is a decentralized blockchain platform that enables smart contracts and dApps. Unlike Bitcoin (primarily a currency), Ethereum is a programmable blockchain.
Key Characteristics:
- Smart Contracts: Self-executing contracts with code
- dApps: Decentralized applications on blockchain
- Ethereum Virtual Machine (EVM): Runtime for smart contracts
- Native Currency: ETH pays for transactions and services
Brief History
- 2013: Vitalik Buterin published Ethereum whitepaper
- 2015: Ethereum mainnet launched
- 2022: The Merge - transitioned from Proof of Work to Proof of Stake
- Present: Largest smart contract platform by ecosystem size
How Ethereum Works
Blockchain Architecture:
- Blocks contain transactions and smart contract code
- Block time: ~12 seconds (after The Merge)
- Gas fees paid in ETH
- Network secured by validators (Proof of Stake)
Smart Contracts:
- Code stored on blockchain
- Executes automatically when conditions met
- Immutable once deployed
- Used for DeFi, NFTs, gaming, tokens
Proof of Stake (PoS):
- Energy-efficient (vs Proof of Work)
- Validators stake ETH to secure network
- Staking rewards available
- Better scalability
Key Features
- Smart Contract Platform: Largest ecosystem
- dApps: DeFi, NFTs, gaming, social platforms
- Energy Efficient: PoS uses much less energy
- Extensive Ecosystem: Developer tools, wallets, exchanges
