Score: 7.8/10 (Innovation: 7, Technical: 9, Documentation: 9, Utility: 6)

A reproducible benchmark framework for limit-order-book matching engines that measures throughput under realistic bursty workloads with a cryptographic audit trail. It reveals that published performance claims for popular open-source matching engines are often misleading because they lack realistic order cancellation patterns and inter-thread report drainage, making this a valuable tool for exchange developers and algorithm researchers.
