Tata Consultancy Services, in a notice to the exchanges on Wednesday, announced the successful completion of a Proof of Concept (PoC) around a blockchain-based non-exchange trade settlement using TCS’ Quartz Blockchain Solution. Developed in collaboration with the Canadian Depository for Securities, a wholly owned subsidiary of TMX Group, the PoC is part of a large market infrastructure transformation programme leveraging TCS BaNCS for Market Infrastructure, aimed at the modernisation of depository, clearing and settlement services in Canada. The PoC helped demonstrate how Delivery versus Payment trade settlement can be completed using tokenised assets held on the Quartz blockchain ledger. In a separate notice, TCS said it is partnering with Intel to integrate Intel Software Guard Extensions technology with the Quartz Blockchain solution to further enhance the privacy and security of blockchain-based ecosystems implemented using Quartz. TCS shares gained 0.40 per cent at ₹1,851.50 on the BSE.
