Ethereum is a decentralized computing network that empowers developers to build and deploy applications on its blockchain using smart contracts. As the second-largest cryptocurrency by market capitalization, Ethereum extends blockchain technology beyond financial transactions, offering versatile solutions across industries.
History of Ethereum
- 2013: Conceptualized by Vitalik Buterin in a whitepaper.
- 2015: Official launch with its genesis block.
- 2022: Transitioned to Proof of Stake (PoS), reducing energy consumption by ~99.95%.
Key Features
- Smart Contracts: Self-executing agreements coded in Solidity.
- Ethereum Virtual Machine (EVM): Runtime environment for deploying contracts.
- Ether (ETH): Native cryptocurrency for transaction fees.
- DApps: Decentralized applications with tamper-proof backends.
- DAOs: Community-led organizations governed by code.

How Ethereum Works
- Transactions trigger EVM execution across all network nodes.
- Gas fees compensate miners; insufficient gas halts transactions.
- Consensus: PoS validates blocks based on staked ETH.
Example: A voting DApp uses smart contracts to ensure transparent, unalterable results.
Ethereum Account Types

FAQ
Q1: What makes Ethereum different from Bitcoin?
A1: Ethereum supports smart contracts and DApps, while Bitcoin focuses solely on peer-to-peer transactions.
Q2: How does PoS improve Ethereum?
A2: PoS replaces energy-intensive mining with staking, making Ethereum greener and faster.
Q3: Can Ethereum scale to mass adoption?
A3: Layer-2 solutions (e.g., rollups) aim to boost transaction speeds beyond base-layer limits.
Conclusion
Ethereum’s blend of smart contracts, DApps, and PoS positions it as a cornerstone of Web3. Its adaptability across sectors—from finance to governance—highlights its transformative potential. As the network evolves, Ethereum continues to pave the way for a decentralized, transparent digital economy.
