What Is Ethereum?
Ethereum (ETH) is a decentralized blockchain platform developed by Vitalik Buterin in 2015, renowned for its smart contract functionality.
- Native Cryptocurrency: The platform’s token, Ether (ETH), ranks second by market capitalization after Bitcoin.
- Versatile Applications: Powers decentralized applications (DApps), DeFi (Decentralized Finance), NFTs, and more.
Key Features of Ethereum
1. Smart Contracts
Self-executing agreements coded on the blockchain, eliminating intermediaries.
- Use Cases: Finance, insurance, real estate, and supply chain automation.
2. Decentralized Applications (DApps)
- Censorship-Resistant: Runs on blockchain, avoiding centralized servers.
- Examples: Games (Axie Infinity), social networks, marketplaces.
3. Token Standards (ERC-20, ERC-721)
- ERC-20: For fungible tokens (e.g., stablecoins).
- ERC-721: For NFTs (unique digital assets).
4. Layer 2 Solutions
- Scalability Fix: Projects like Arbitrum and Optimism use ETH for gas fees, reducing costs.
How Ethereum Works
Consensus Algorithm
- From PoW to PoS: Transitioned in September 2022 ("The Merge") to cut energy use by 99.95%.
Gas Fees
- Dynamic Pricing: Fees fluctuate based on network demand.
