So we see this as an incremental evolution, even though the underlying technology we're using is based on DLT, customers can still connect using messaging, and they can opt into the DLT solutions as it makes sense for them," Campbell said. "One thing we are mindful of, though, is we don't want to force our customers to adopt a pace of change, which is faster than makes sense for them. The only difference is they will need to do so using the ISO2022 messaging standard. If they don't wish to take a node, they can still communicate with the exchange through messaging. The ASX wants its customers to be able to opt in, when it makes sense for them.

In a permissioned DLT, what you end up with is shared business logic, but the actual data is only available to entitled users. "In a public blockchain solution, everyone has access to all of the data.
In this instance, the ASX is lucky it is trusted as the default in the market, as trust is fundamental for the DLT solution. In that case, that legal approval relates to trust in the system and a very important element." Each transaction refers to the previous transaction, and is cryptographically signed by a legal approver. We have a copy, our customers have a copy - anyone who takes a node has a copy of the ledger - all synchronised. "For us, DLT-based CHESS is the next generation of market infrastructure, moving away from the notion of a central database messaging to distributed database shared with our customers, allowing for real time source of truth to be shared, whilst also preserving privacy and integrity," Campbell explained. If there's ever a change, everyone has to ripple through that change.Ĭampbell expects this to be a lot more efficient with DLT. "We're re-platforming that with DLT - we're talking about a real industrial-style, mission-critical solution."ĬHESS sits at the heart of banks and brokers as they exchange information about trading CHESS is constantly sending messages back and forth to reconcile the industry view of the clearing and settlement data for the Australian equities market.Īpart from the operator, everyone's operating on a copy of the data and not operating on the source of truth. "That's what we call equity post trade and it represents about 13% of our business.
"If I was to buy a BHP share from my friend Rob, there'd actually be 15 people in that chain of transfer and all that's actually happening is I'm giving Rob some money and the name on the title in the CHESS database is changing from Rob's to mine, yet there are 15 organisations in that chain," Campbell explained.

Speaking at the Gartner Application Architecture, Development, and Integration Summit in Sydney on Tuesday, Campbell provided further information on CHESS, now the ASX is actually moving forward with actual progress. According to ASX general manager of engineering and architecture David Campbell, the distributed ledger (DLT) project is a marathon, not a sprint. The ASX is about 30-40% through its major functional build, planning for industry-wide testing of the new system in 2020, and after a few push backs, go-live for the new system is slated for 2021. At the time, there were no globally accepted standards for data exchange, so the ASX created its own proprietary protocol. When it was commissioned in the 1990s, CHESS was seen as an innovative, world-leading solution. Per day, around AU$5 billion is processed through CHESS, and 300-500 transactions and up to 1,500 messages are processed per second. There's about AU$2 trillion worth of equities registered in CHESS. It also has specific uses for the enterprise.
