3.4.1 Fully Anonymous Order Book

Adopting zk-Rollups (Zero-Knowledge Rollup) technology, all transaction matching processes are moved to the off-chain "aggregator", and only the transaction results (verified through Zero-Knowledge Proof) are submitted to the Imperium Chain main chain. This model brings two major advantages:

• Absolute privacy: Only the Zero-Knowledge Proof of "transaction completed" is recorded on the main chain, without sensitive information such as the addresses of both buyers and sellers, transaction amount, and order price. Third parties cannot trace the transaction details.

• Zero Gas fee + high speed: Off-chain matching avoids main chain congestion. The transaction confirmation time is shortened to 1-2 seconds, and users do not need to pay main chain Gas fees (only a small handling fee needs to be paid to the aggregator, settled in AIS).
