Introduction to Ethereum
Ethereum is the world’s second-largest cryptocurrency project by market capitalization and the first blockchain to introduce smart contract functionality. This innovative platform goes beyond simple transactions, enabling developers to build decentralized applications (dApps) that reshape how we interact with the internet.
Key Features:
- Smart Contracts: Self-executing agreements with predefined rules.
- Decentralized Applications (dApps): Leaderless apps resistant to censorship.
- Native Cryptocurrency: Ether (ETH) fuels transactions and operations.
How Ethereum Works
Ethereum operates on a blockchain—a decentralized ledger maintained by a global network of nodes. Unlike Bitcoin, which focuses on peer-to-peer payments, Ethereum’s vision is broader: to create a "world computer" where users control their data and finances without intermediaries.
Core Components:
- Ether (ETH): The cryptocurrency used for transactions and gas fees.
- EVM (Ethereum Virtual Machine): Executes smart contracts across the network.
- Consensus Mechanism: Transitioned to proof-of-stake (PoS) in 2022 via "The Merge," reducing energy use by 99%.

Ethereum vs. Bitcoin
| Feature | Ethereum | Bitcoin |
|---|---|---|
| Primary Use | Decentralized apps & smart contracts | Digital gold & payments |
| Consensus | Proof-of-Stake (PoS) | Proof-of-Work (PoW) |
| Supply | No hard cap | Capped at 21 million BTC |
| Speed | Faster transactions | Slower, more secure transactions |
The Decentralized Internet Vision
Ethereum aims to replace intermediaries (e.g., Google, Facebook) with trustless systems. For example:
- Social Media: Users own their data instead of platforms.
- Finance: Smart contracts automate loans/insurance without banks.

Ethereum FAQs
1. How is Ethereum different from Bitcoin?
Ethereum extends blockchain technology beyond payments to support dApps and programmable contracts, while Bitcoin focuses on being a decentralized currency.
2. Why is Ethereum called a "world computer"?
Its global node network processes smart contracts, enabling a decentralized internet where users control their data.
3. What was "The Merge"?
The 2022 upgrade shifted Ethereum from energy-intensive PoW to eco-friendly PoS, though scalability challenges remain.
4. How do dApps work?
They run on Ethereum’s blockchain, requiring ETH for transactions. Examples include DeFi platforms like Uniswap and NFT marketplaces.
5. What’s next for Ethereum?
Solving high fees and slow speeds via Layer 2 solutions (e.g., rollups) is critical for mass adoption.
Conclusion
Ethereum’s innovation lies in its flexibility—powering everything from DeFi to NFTs. While challenges like scalability persist, its vision of a user-owned internet continues to drive development. As the ecosystem evolves, Ethereum remains at the forefront of blockchain’s potential to redefine digital interactions.
