Scalable Decentralized Exchange Data Architecture: Addressing Liquidity, Latency, and MEV Protection Issues

Reported by Bijie Network: As the market share of decentralized exchanges (DEX) grows, the focus has shifted from basic smart contracts to addressing the "trilemma" of high-load trading: ensuring sufficient liquidity, minimizing sub-second latency, and protecting users from MEV attacks. A robust DEX requires a holistic system approach, prioritizing concentrated liquidity for core trading pairs, continuous security monitoring that goes beyond audits, and infrastructure such as off-chain indexers to achieve speeds and user experiences comparable to centralized exchanges. The key to success lies in building a reliable and scalable trading system, not just deploying code.
