What is Ethereum?

Ethereum (ETH) is a leading cryptocurrency and decentralized platform launched in 2015 by Vitalik Buterin. Unlike Bitcoin, Ethereum enables smart contracts and decentralized applications (dApps), revolutionizing digital transactions and internet-based services.

Key Features:

• Decentralized: No central authority controls the network.
• Multifunctional: Supports dApps, token creation, and complex financial operations.
• Native Currency: Ether (ETH) fuels transactions and smart contracts.

How Does Ethereum Work?

Ethereum operates as an open-source blockchain optimized for dApps and smart contracts. Its core innovations include:

Proof-of-Stake (PoS) Consensus

Since September 2022, Ethereum transitioned from energy-intensive Proof-of-Work (PoW) to Proof-of-Stake (PoS), enhancing:

• Energy efficiency: 99.95% less energy use than PoW.
• Security: Validators stake ETH as collateral, discouraging malicious behavior.
• Accessibility: No specialized hardware required.

Ethereum Virtual Machine (EVM)

The EVM executes Solidity-based smart contracts, enabling:

• Automated agreements (e.g., loans, trades).
• Gas fees: Computational costs paid in ETH (calculated as: Gas Used × Gas Price).

The ETH Token

• Purpose: Pays for transactions, smart contracts, and dApp operations.
• Supply: Uncapped but with controlled inflation to incentivize validators.

Ethereum’s Technology Stack

1. Smart Contracts: Self-executing code on the blockchain.
2. Gas Mechanism: Ensures fair pricing for network resources.
3. Governance: Managed by the Ethereum Foundation and global developer community.

The Ethereum Ecosystem

Decentralized Finance (DeFi)

Ethereum hosts 80%+ of DeFi projects, enabling:

• Peer-to-peer lending/borrowing.
• Yield farming and decentralized exchanges (DEXs).

Non-Fungible Tokens (NFTs)

• Unique digital assets (art, collectibles) traded via Ethereum.
• Marketplaces: OpenSea, Rarible leverage ETH for transactions.

Pros and Cons of Ethereum

✅ Advantages

• High security and adoption.
• Institutional backing (e.g., ING Bank).
• Robust developer tools.

❌ Challenges

• Network congestion during peak usage.
• Competition from newer blockchains.

Ethereum’s Founder: Vitalik Buterin

• Published Ethereum’s whitepaper in 2013.
• Continues to guide Ethereum’s development.
