## On-Chain Order Book

An on-chain order book is a decentralized exchange mechanism where all buy and sell orders are recorded directly on the blockchain ledger. Unlike traditional centralized exchanges that use off-chain databases, this system executes trades through smart contracts that hold assets in escrow.

Market participants submit limit orders that are transparently visible to all network participants, ensuring public verification of price discovery. Because every action is a transaction on the blockchain, the order book remains immutable and trustless.

This structure eliminates the need for intermediaries to match trades, as the protocol logic handles matching and settlement automatically. However, this transparency can sometimes expose traders to front-running risks by automated bots monitoring the mempool.

It represents a fundamental shift in market microstructure by bringing the entire trading lifecycle into the public domain.
