What Is the Fundamental Difference between an Automated Market Maker (AMM) and a Traditional Limit Order Book?
A traditional limit order book (LOB) matches buyers and sellers based on specific prices and quantities set by users. Liquidity is provided by users placing limit orders.
An AMM, however, uses a mathematical function to price assets and provide continuous liquidity. Users trade directly against the pool's reserves, and the price is determined algorithmically by the ratio of assets in the pool.
LOBs are common in centralized exchanges, while AMMs power decentralized exchanges (DEXs).
