How Does a ‘Liquidity Pool’ in DeFi Differ from a Centralized Exchange Order Book?
A liquidity pool, used by Automated Market Makers (AMMs) on DEXs, holds two or more tokens and uses a mathematical formula to determine the price. It does not use a traditional order book of bids and asks.
Trades are executed against the pool's assets. The CEX order book uses matching engine logic to pair buyers and sellers.
Liquidity pools introduce 'impermanent loss' but eliminate the need for a direct counterparty.
