Definition
The live list of buy and sell orders waiting to be matched.
An order book shows every resting bid and ask at each price. Bids sit below the current price, asks above it, and the gap between the best of each is the spread.
Centralized exchanges have always worked this way. Onchain, order books were impractical until chains got fast enough, which is why AMMs dominated first.
In practice
Reading depth on the book tells you where large buyers and sellers are waiting, which often marks where price stalls.

Want this explained out loud?
Some of these land faster in conversation than in writing. Sessions are one to one and you can ask anything, including the things that feel too obvious to ask.
