Understanding the Digital Currency Era
Core Concepts
- Cryptocurrencies: Digital assets like Bitcoin and Ethereum.
- Distributed Ledgers: Immutable records maintained across networks.
- Consensus Mechanisms: Proof-of-Work (PoW) vs. Proof-of-Stake (PoS).
Practical Applications
- Cross-border payments
- Tokenized assets
- Supply chain tracking
Decentralized Finance (DeFi): A New Frontier
DeFi leverages blockchain to create open financial systems without traditional banks. Notable features:
- Lending Protocols: Earn interest on crypto holdings.
- DEXs (Decentralized Exchanges): Trade directly peer-to-peer.
- Stablecoins: Cryptocurrencies pegged to fiat values.
Demystifying Crypto Technologies
