Danish Sugar Beet Auction

Last updated

The Danish Sugar Beet Auction was the first large-scale and practical application of secure multi-party computation, which took place in January 2008. [1] [2] [3] An electronic double auction was successfully run by a multiparty computation involving representatives of Denmark's only sugar beets processor (Danisco), the Danish sugar beet growers' association, and a research group responsible for implementing and running the computation. [2]

Due to European Union sugar market policy reforms which reduced sugar subsidies and lowered prices, [4] as well as the recent closure of one of Danisco's sugar processing plants, the Danish sugar beet industry needed to reallocate production contracts to farmers nation-wide in an attempt to retain market efficiency. The decision made was to hold an electronic double auction to find the new market clearing price of sugar beets, where the role of the "auctioneer" was played by a computer program implementing a secure multi-party computation (SMPC) between the farmers and Danisco.

The use of SMPC not only reduced expenses of the auction process (when compared to hiring an external consultancy to run the auction), but also allowed farmers' bids to remain private from Danisco, the only sugar beets processor on the Danish market and the seller of production contracts. [1] This was important as farmers' bids can reveal their individual economic positions and productivities, which Danisco could have hypothetically used to their advantage when selling contracts. In a survey of the auction participants, 80% of respondents indicated that it was important to them that the bids were kept confidential. [1]

Aside from organizing the logistics of such a novel auction, the actual computation of the market clearing price and each bidder's positions only took about 30 minutes to complete. [1] Ultimately, the auction resulted in the transfer of 25 thousand tons of production rights between farmers. [1]

A commodity market is a market that trades in the primary economic sector rather than manufactured products, such as cocoa, fruit and sugar. Hard commodities are mined, such as gold and oil. Futures contracts are the oldest way of investing in commodities. Commodity markets can include physical trading and derivatives trading using spot prices, forwards, futures, and options on futures. Farmers have used a simple form of derivative trading in the commodity market for centuries for price risk management.

An auction is usually a process of buying and selling goods or services by offering them up for bids, taking bids, and then selling the item to the highest bidder or buying the item from the lowest bidder. Some exceptions to this definition exist and are described in the section about different types. The branch of economic theory dealing with auction types and participants' behavior in auctions is called auction theory.

An electricity market is a system that enables the exchange of electrical energy, through an electrical grid. Historically, electricity has been primarily sold by companies that operate electric generators, and purchased by consumers or electricity retailers.

A cryptographic protocol is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program.

Secure multi-party computation is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private. Unlike traditional cryptographic tasks, where cryptography assures security and integrity of communication or storage and the adversary is outside the system of participants, the cryptography in this model protects participants' privacy from each other.

A double auction is a process of buying and selling goods with multiple sellers and multiple buyers. Potential buyers submit their bids and potential sellers submit their ask prices to the market institution, and then the market institution chooses some price p that clears the market: all the sellers who asked less than p sell and all buyers who bid more than p buy at this price p. Buyers and sellers that bid or ask for exactly p are also included. A common example of a double auction is stock exchange.

Sugar production in the United States Virgin Islands was an important part of the economy of the United States Virgin Islands for over two hundred years. Long before the islands became part of the United States in 1917, the islands, in particular the island of Saint Croix, was exploited by the Danish from the early 18th century and by 1800 over 30,000 acres were under cultivation, earning Saint Croix a reputation as the "Garden of the West Indies". Since the closing of the last sugar factory on Saint Croix in 1966, the industry has become only a memory.

The sugar industry of the United States produces sugarcane and sugar beets, operates sugar refineries, and produces and markets refined sugars, sugar-sweetened goods, and other products. The United States is among the world's largest sugar producers. Unlike most other sugar producing countries, the United States has both large and well-developed sugarcane and sugar beet industries. Refined sugarcane, processed sugar beet, and high-fructose corn syrup are all commonly used in the U.S. as added sugars to sweeten food and beverages.
