[News] Decentralized limit order books (LOB) may become the best choice between DeFi and centralized exchanges. Although automated market makers (AMMs) dominate the DeFi field, their capital efficiency is low, resulting in large user slippage. In contrast, limit order books on centralized exchanges offer lower slippage. However, there are risks associated with entrusting funds to a centralized entity. Decentralized LOB provides excellent execution quality while retaining user assets. Currently, a new generation of high-throughput blockchains are gradually making fully on-chain LOBs more feasible, such as Econia (Aptos), DeepBook (Sui), and OpenBook/Serum (Solana).
