HSBCO carries out tests on digital Hong Kong dollar (e-HKD) using public blockchains for central bank digital currency (CBDC) applications.

In a groundbreaking move, HSBC, the renowned global bank, has delved into the realm of digital finance by exploring e-HKD (digital Hong Kong dollar) payments on public blockchains. This innovative approach carries significant implications for privacy and decentralized identity in digital transactions.

The bank's trials, as part of Hong Kong Monetary Authority’s Project e-HKD+, have focused on deploying Privacy Enhancing Technologies (PET) to ensure that while transactions remain transparent and verifiable on public blockchains, sensitive user data and transactional details are protected from unauthorized access. This balance aims to sustain both trust and confidentiality in digital currency use.

HSBC has also examined the integration of Decentralized Identity frameworks to reinforce secure and private digital interactions. Decentralized identities enable users to control their personal data without relying on centralized authorities, reducing privacy risks and enabling compliant digital currency transactions. This approach aligns with the goal of enhancing privacy while ensuring regulatory compliance and operational security across blockchain networks.

By successfully testing e-HKD on public blockchains with privacy and decentralized identity measures, HSBC advances the viability of a scalable, secure, and private digital currency ecosystem. The importance of these technologies for mainstream adoption is underscored by a survey revealing that 90% of respondents prioritized privacy.

Moreover, HSBC’s bank-led on-chain settlement service demonstrates how traditional banking infrastructure can coexist and innovate within decentralized environments. The bank has recently launched its tokenized deposit service in Hong Kong, with Ant International as the first client.

HSBC's work on e-HKD is not limited to retail central bank digital currency (CBDC). The bank has also investigated how to make private payments in a public environment and explored private enhancing technologies (PETs) and decentralized identity. The bank developed a private DLT solution using Hyperledger Besu, which is presumed to act as a tokenization platform prior to public issuance.

The bank's efforts in this field are a significant step towards fostering a more secure and user-centric framework for digital currency transactions in Hong Kong’s financial ecosystem. As central banks worldwide explore digital currencies, HSBC's pioneering work serves as a model for integrating privacy protection technologies and decentralized identity solutions with the transparency and efficiency of blockchain.
