CEX Vs DEX Comparison

Architecture

Centralized exchanges (CEXs) represent a traditional intermediary model, functioning as custodians of user funds and employing an order book system for matching buy and sell orders, while decentralized exchanges (DEXs) operate via smart contracts, enabling peer-to-peer trading directly from user wallets. This fundamental difference in architecture dictates varying levels of control and trust, with CEXs requiring users to trust the exchange’s security and operational integrity, and DEXs shifting that trust to the underlying code. Consequently, CEXs typically offer higher liquidity and faster execution speeds due to their centralized infrastructure, whereas DEXs prioritize censorship resistance and user autonomy. The architectural divergence impacts the scalability and efficiency of each system, influencing transaction costs and throughput.
