5.2 The order book
The order book at the core of the decentralized
exchange differs a lot from traditional
decentralized exchange approaches. The
Herdius order book should be imagined like a
central hub that matches orders from all the
makers as they come in. Thus, it is a collection
of order information and has the purpose of
order settlement and peer matching rather
than anything else. The order book is most
similar to an order-matching-party that
instructs users about which other users to
query regarding a specific order.

communication system that provides bidirectional
sender and receiver anonymity as
well as outside unobservability. As low-latency
is key, our proposed peer-order-matching
mechanism will be based on the Loopix
anonymity system (Danezis), a mix networkbased
architecture that uses Poisson mixing
which is capable of independently delaying
messages to further prevent third party
linkability.
