Ethereum and Smart Contracts Explained
Ethereum: More Than Just a Cryptocurrency
While Bitcoin introduced decentralized digital currency, Ethereum expanded blockchain’s potential with smart contracts—self-executing agreements coded into the blockchain.
Key features:
- Decentralized Applications (DApps): Developers build programs on Ethereum’s blockchain.
- Ether (ETH): The native cryptocurrency fueling transactions.
- Scalability: Innovations like Ethereum 2.0 improve speed and reduce fees.
Smart Contracts: The Backbone of DeFi
Smart contracts automate agreements without intermediaries. Examples:
- Lending platforms: Loans execute automatically when conditions are met.
- NFT marketplaces: Ownership transfers instantly upon payment.
- Supply chains: Transparency in product tracking.
How Blockchain Combats Financial Tech Hegemony
Traditional finance relies on centralized institutions (banks, governments). Blockchain disrupts this by:
✅ Eliminating middlemen – Reduces fees and delays.
✅ Enabling transparency – Public ledgers prevent fraud.
✅ Empowering individuals – Full control over assets.

Best Practices
- Use Reputable Exchanges – Prioritize platforms with strong security (e.g., two-factor authentication).
