Interview: Disruptive Technologies and Blockchain

At the EXTENT-2018 event held by Exactpro on 20 June 2018 in London, Timothy Hogben, Chief Operating Officer with ASX, spoke with Elena Trescheva, Exactpro’s Business Development Manager and Researcher. Mr. Hogben elaborated on the exchange’s plans to replace CHESS (Clearing House Electronic Subregister System) with a DLT based system.

In his interview, Mr. Hogben spoke about ASX’s plans of implementing a blockchain system, the main findings from a two-year exploratory process, the exchange’s transition to Agile and how it has affected the overall delivery process.

My main responsibility is for the live environments and I run technology in the operation groups. We have about six licenses across trading, clearing and settlement and run a large data center colocation facility for the exchange as well. So we, like most exchanges in this world, are a global market. We are open 24 hours about five and a half days a week and we compete very hard in a very competitive space. The exchange space is a very competitive space. We are a top-ten exchange globally and we do that really hard from an innovation perspective and using technology really well, so we can't afford to have mistakes and make mistakes with our choices. And, you know, we are about one third of the size of other exchanges from a people perspective, so the use of technology is significant in our footprint. In saying that you know we've certainly gone down a path and taken a leadership position in blockchain technology quite rare for the exchange”.
