Decentralized vs. Centralized Exchanges
Blockchain's core philosophy—decentralization—shapes trading platforms:
Decentralized Exchanges (DEX)
- Direct blockchain transactions via smart contracts
- Users retain full asset control in personal wallets
- Enhanced privacy with no KYC requirements
- Examples: EtherDelta, KyberNetwork
Centralized Exchanges (CEX)
- Database-driven trading (off-chain settlements)
- Mandatory identity verification (KYC)
- Better liquidity and faster transactions
- Examples: Binance, OKEx
Key Trade-offs:
DEXs excel in trust minimization while CEXs dominate in speed and market depth.
How Do Hackers Breach Exchanges?
Three primary attack vectors:
- System Vulnerabilities
Complex blockchain systems may contain exploitable bugs. - Hot Wallet Compromises
Online storage solutions (e.g., Mt.Gox) are prime targets. - Account Takeovers
Phishing attacks or credential leaks endanger user funds.
