The ASX will move its equity markets settlement and clearing system onto blockchain-inspired technology being developed by a New York start-up run by Blythe Masters.In an announcement that will be of significant interest to global exchanges and the technology industry, ASX said on Thursday morning it was comfortable replacing its ageing CHESS system with a new one using distributed ledger technology (DLT).The exchange has not specified the timing for the move.The technology is being developed by Digital Asset Holdings, in which ASX has an equity stake, and is run by Ms Masters, a former JP Morgan investment banker.Distributed ledger technology operates like a blockchain but does not require transactions to be confirmed by an external network of computers. It will replace the central ledger operated by CHESS with a synchronised one, held on the systems of each market participant. This computer architecture creates a single source of the true state of the ledger.ASX believes it will create efficiencies for market participants by removing the need for records to be reconciled against a central system. Costs could be saved, once the system is operating, by reducing headcount for back office reconciliation roles.Dominic Stevens, ASX managing director and CEO, said in a statement the DLT system “will enable our customers to develop new services and reduce their costs, and it will put Australia at the forefront of innovation in financial markets.”“While we have a lot more work still to do, today’s announcement is a major milestone on that journey,” he said.ASX deputy CEO Peter Hiom said ASX “has formed a strong partnership with Digital Asset over the past two years, and we’re confident we have chosen the right partner.”Shares are inching higher in early trading, with gains in consumer staples companies working to offset more losses in the mining sector.The S&P/ASX 200 index added 4 points, or 0.1 per cent, to 5950 while the All Ordinaries rose 3 points, or 0.1 per cent, to 6033.

The country is the biggest buyer of industrial metals.A strengthening dollar,which makes raw materials priced in the greenback more expensive to holders of other currencies, also pinched prices.Aluminum, one of the best-performing commodities of 2017, is wavering as signs that China’s growth is slowing fuel concerns about demand just as doubts grow about the Asian nation’s plans to reduce smelter production.Those concerns have rippled through the London Metal Exchange this week, with the bourse’s main gauge dropping by the most in a year on Tuesday.“Yesterday’s sharp decline has no doubt prompted us to reevaluate our bullish bias toward the market going into year-end,” Edward Meir, an analyst at INTL FCStone in New York, said in a note to clients on Wednesday.Aluminum for delivery in three months fell 1.6 per cent to settle at $2,019 a metric at 5:50 p.m. in London.
