What Is the Significance of a ‘Liquidity Pool’ in a Decentralized Exchange (DEX) Context?

A liquidity pool is a collection of funds locked in a smart contract that facilitates trading on a DEX via an Automated Market Maker (AMM). It is the source of liquidity for all trades.

Its significance is that its size and the ratio of its assets directly determine the slippage and pricing, replacing the traditional order book mechanism.
