## On-Chain Order Book Architecture

On-chain order book architecture involves hosting a traditional limit order book directly on a blockchain, where orders are matched via smart contracts. Unlike automated market makers, this approach provides traders with granular control over their execution price and order size, mirroring the experience of centralized exchanges.

However, it faces significant challenges regarding scalability and cost, as every order placement, cancellation, and match requires a transaction fee and on-chain processing. To mitigate these issues, many protocols use off-chain matching engines with on-chain settlement.

This hybrid model aims to combine the transparency and security of blockchain with the performance of centralized order books, which is vital for high-frequency trading in derivatives.
