Our report, "Cyber-Catastrophe Insurance-Linked Securities On Smart Ledgers" (November 2018), postulated how Smart Ledgers could be useful in providing indices, in this case for cyber-catastrophe. Smart Ledgers have advantages of being incorruptible, distributed, and able to automate such functions as delayed releases to specific users of an index. For the report, the pilot software was implemented on ChainZy (SmartChainZ) as well as a central database.
The smart ledger approach provides greater independence for the trigger, and a significant, additional, cyber defence. Armed with this research, Z/Yen, would be very interested in taking cyber catastrophe ILS development forward with any brokers, underwriters, investment banks, or rating agencies.
