DESCRIPTION:Julian WILLIAMS (Durham University)\nFutures exchanges\, such 
 as the Chicago Mercantile Exchange\, are the embodiment of centralized fin
 ancial intermediation. Complex interactions between economic and security 
 properties and the exchange's essentially non-monotonic security behavior 
 affecting the eligibility of a party's asset in a protocol are a challenge
  for security research. We present the key security properties of an Excha
 nge\, needed to guarantee its economic viability (availability of trading 
 information\, confidentiality of positions\, absence of price discriminati
 on\, global integrity management)\, and show how to implement all key mark
 et business functionalities in a secure\, fully distributed setting. Our d
 istributed protocol simulates the centralized functionality in the general
  case of asynchronous communication\, under the usual assumptions of anony
 mity of the physical transmission layer and availability of a distributed 
 ledger. The results of our proof of concept implementation (based on zk-SN
 ARKs and SPDZ) shows that the computations corresponding to actual trading
  days (according to the Thomson-Reuters Tick History Database) are within 
 engineering reach.
