Centralised venues decide what to publish. Depth is usually aggregated, positioning is inferred, and the parts that would be most informative are the parts nobody shows. On-chain liquidity has the opposite property: the full state is public by construction, because the pool is a contract and the contract holds the numbers.
What is visible
For a concentrated liquidity pool, you can see exactly how much capital is deployed in each price band, who deployed it and when. Not an estimate — the actual positions. That is a completeness no order book offers.
You can also see the fee tier, the current price within the range structure, and how the deployed capital shifts as providers reposition.
Why the shape matters
Concentrated liquidity means most capital sits inside a band and there is very little outside it. Within the band, trades move price slowly. Outside it, the same size moves price a great deal.
So the edges of the dense region function like structure, and unlike most structure you can measure exactly where they are rather than inferring them from where price previously turned.
Reading it against centralised books
The pool and the centralised order book are arbitraged against each other, which means they are not independent. But they are not identical either: the pool has capital in places the book does not, and the book has participants who will not touch the chain.
A level defended in both is stronger than one defended in either alone. A gap in both is where fast moves happen.
The limits
Providers can withdraw. A range that looks well-funded is well-funded until the provider removes it, which can happen in one transaction. And a chain-level view says nothing about who is behind a position or why, which is a limit shared with every other structural read.
