Discover Ethereum's revolutionary technology, including its blockchain, smart contracts, decentralized applications (dApps), and native cryptocurrency Ether (ETH). As the second-largest cryptocurrency by market capitalization, Ethereum powers a vast ecosystem of decentralized solutions beyond simple transactions.
Ethereum Basics
History of Ethereum
Ethereum was conceptualized in 2013 by Vitalik Buterin and launched in 2015 following an $18 million ICO. Key milestones include:
Major Hard Forks:
- DAO Fork (2016): Created Ethereum and Ethereum Classic
- Byzantium (2017): Reduced mining rewards
- The Merge (2022): Transitioned to proof-of-stake
Recent Upgrades:
- Dencun (2024): Introduced proto-danksharding for L2 scalability
Ethereum vs. Bitcoin Comparison
| Feature | Ethereum | Bitcoin |
|---|---|---|

Key Components
1. Ethereum Blockchain
A decentralized ledger maintained by global nodes, recording all transactions and smart contract executions.
2. Ether (ETH)
- Network fuel for transactions and dApp operations
- Used for gas fees (computational effort payments)
- Staking asset in PoS system
3. Smart Contracts
Self-executing agreements that power:
- DeFi protocols
- NFT marketplaces
- DAO governance systems
4. Decentralized Applications (dApps)
Over 4,000 active dApps across categories:
- DeFi (Uniswap, Aave)
- Gaming (Axie Infinity)
- Social (Lens Protocol)
5. Ethereum 2.0 Upgrades
- Beacon Chain: PoS coordination
- The Merge: Completed PoS transition
- Dencun: Enhanced L2 scalability
