Abstract

In a trading system providing an anonymous market, orders in the market are executed using cryptographic keys. Traders can view the orders and use their specific key to determine the particular rating of an order in accordance with the trader's own preferences. Since the same order information is sent to all traders, the bandwidth and processing requirements are kept at a minimum.
