HSBC has successfully trialed the first application of quantum-secure technology for buying and selling tokenized physical gold. This innovative approach comes one year after the bank began tokenizing gold bullions using distributed ledger technology (DLT).
Partnering with Quantum Technology Provider
On September 19, HSBC announced the successful test of quantum-secure methods to safeguard these assets against potential future quantum computing attacks. The bank collaborated with Quantinuum, a UK-US joint venture quantum technology provider, to implement Quantum Origin, a quantum randomness technology.
Enhancing Interoperability and Security
During the trial, HSBC also examined the interoperability of its gold tokens using Quantinuum’s post-quantum cryptography (PQC) algorithms to securely move digital assets across distributed ledgers via secure networks. This included the ability to convert HSBC gold tokens into ERC-20 fungible tokens, improving distribution and interoperability with various DLTs and digital wallets.
Standardization and Future Quantum Security
The suite of algorithms tested in this trial is currently in the process of standardization by the US National Institute of Standards and Technology (NIST) and is designed to resist future quantum computing attacks. This advancement ensures the security of tokenized assets in the face of evolving security threats.
Expanding Access to Gold Tokens
In line with these developments, earlier in 2024, HSBC introduced its Gold Token for retail investors in Hong Kong, enabling them to own fractional shares of physical gold. This initiative aims to democratize access to gold ownership and diversify investment opportunities for a broader range of investors.
Philip Intallura, Global Head of Quantum Technologies at HSBC, emphasized the success of the pilot in showcasing the practical application of advanced technologies in a business environment. While the timeline for deploying quantum-safe methods to protect real Gold Token assets remains undisclosed, the successful trial marks a significant step towards enhancing security measures within the banking industry.
