What Is Ethereum?
Ethereum is a decentralized blockchain platform launched in 2015 by Vitalik Buterin. Unlike Bitcoin, which focuses on peer-to-peer transactions, Ethereum enables programmable applications through smart contracts—self-executing agreements that run automatically when predefined conditions are met.
Ether (ETH), Ethereum’s native cryptocurrency, serves two key purposes:
- A tradable digital asset.
- "Fuel" (gas) for running decentralized applications (dApps).
With 10-second transaction speeds (vs. Bitcoin’s 10 minutes) and unmatched flexibility, Ethereum has solidified its position as the second-largest cryptocurrency by market cap.
Its core vision? Building a decentralized internet where apps, contracts, and transactions operate without intermediaries.
Key Features of Ethereum
1. Smart Contracts
Self-executing code that eliminates intermediaries in agreements (e.g., insurance payouts, loans).
2. Decentralized Applications (dApps)
From DeFi to NFTs, Ethereum hosts thousands of dApps across industries.
3. Proof of Stake (PoS)
Since The Merge (2022), Ethereum uses PoS, slashing energy use by 99% vs. Bitcoin’s Proof of Work.
4. Layer 2 Scaling
Solutions like rollups boost throughput to 2,000+ TPS, reducing fees.

| 2016 | DAO hack → Ethereum Classic split | Highlighted security risks |
| 2020 | DeFi Summer explosion | TVL surged to $100B+ |
| 2022 | The Merge (PoS transition) | Cut energy use by 99% |
| 2024 | Ethereum Spot ETFs approved | Institutional adoption soared |
| 2025 | ETH peaks at $4,092 | Driven by ETF inflows and Trump’s pro-crypto policies |
Ethereum Use Cases
1. Decentralized Finance (DeFi)

3. Web3 & DAOs
User-controlled internet and leaderless organizations (e.g., MakerDAO).
4. Tokenization
Real-world assets (real estate, stocks) represented as blockchain tokens.
