PolyU wins ZPRIZE 2023 for blockchain innovation again demonstrating groundbreaking research in zero-knowledge proofs

The research team led by Prof. Allen AU Man Ho, Professor of the Department of Computing at The Hong Kong Polytechnic University (PolyU) and Dr Lu Xingye, Research Assistant Professor, have won an award in the international ZPRIZE competition for the second consecutive year for their pioneering work in zero-knowledge proofs (ZKPs). Their groundbreaking work in this field has profound implications for enhancing privacy and scalability in blockchain and Web3 applications. Prof. Christopher CHAO, PolyU Vice President (Research and Innovation), said, “We take great pride that PolyU academics continue to gain worldwide acclaim for driving innovation in cutting-edge technologies like blockchain and zero-knowledge cryptography. This award underscores the exceptional capabilities of our research team and their pioneering work in accelerating the development and real-world adoption of zero-knowledge encryption.” The annual ZPRIZE competition, spearheaded by the blockchain industry in 2022, promotes the advancement of ZKPs by open-sourcing winning submissions for the reference of the general public. ZKPs allows a “prover” to convince a person of the validity of a computation without leaking any information; it is hence referred to as zero-knowledge cryptography. This year, the PolyU team have triumphed in the “High Throughput Signature Verification” open division category, winning a cash prize of US$250,000. They were tasked with verifying the greatest number of Elliptic Curve Digital Signature Algorithm (ECDSA) signatures in a given time using ZKPs. ECDSA signatures are used to prove the authenticity and integrity of digital messages over the internet, as well as of blockchain transactions on networks such as Bitcoin and Ethereum. Making it more efficient to cryptographically verify those signatures inside a ZKP is important for creating a better user experience and enables numerous real-world applications. The PolyU team’s innovative approach can generate ZKPs for the digital signatures of 50 1KB messages on a regular laptop computer within ten minutes, laying a solid foundation for future applications of ZKPs in ECDSA verification. It also reduces the complexity of generating proofs for a 5MB message’s digital signature to a maximum of 6.2 million constraints compared to over 50 million constraints previously - a minimum eight-fold reduction. As a pioneer in blockchain education and research in Hong Kong, PolyU has introduced Hong Kong’s first Master of Science in Blockchain Technology programme. It has also initiated doctoral programmes relating to financial technology, as well as bachelor’s degree programmes relating to FinTech and Artificial Intelligence (AI). On the research front, the University has established the Research Centre for Blockchain Technology, the first research centre in Hong Kong whose research studies full-stack blockchain technology. According to the “Best Universities for Blockchain 2022” rankings by CoinDesk, PolyU has been ranked the No. 1 university for blockchain in the world.

PolyU researchers develop novel fungus-based fat replacer AkkMore™ to prevent obesity and enhance gut health; collaborates with Hotel ICON to launch reduced-fat desserts to promote environmental innovation in food industry

In recent years, scientists have been actively exploring the potential of future foods, including using boundless microorganisms as substitutes for limited animal and plant resources. Among these microorganisms, the replacer of animal-derived fats is a research topic currently of very great interest. A research team from the Research Institute for Future Food (RiFood) and the Department of Food Science and Nutrition (FSN) of The Hong Kong Polytechnic University (PolyU) has successfully developed AkkMore™, a novel fungus-based fat replacer which is effective in preventing obesity and metabolic diseases, enhancing gut health, modulating immune response and relieving anxiety. This replacer not only helps lower the calorific content of food, but also extends the shelf life of cream products. In the long term, it can reduce dairy consumption and food waste, providing innovative ESG (Environmental, Social and Governance) solutions in the food industry. A PolyU research team led by Dr Gail CHANG, Core Member of RiFood and Research Assistant Professor of FSN together with Dr Amber CHIOU, Associate Director and Associate Professor of RiFood, and Associate Head of FSN has extracted the functional component of AkkMore™ from natural fungus to develop the replacer and has conducted three phases of animal experiments. The study has found that mice which had been administered the AkkMore™ formula had a healthier gut microbiota with higher density of Akkermansia, lower Firmicutes/Bacteroidetes ratio, lighter adipose tissue and suppressed neuroinflammation when compared to the control group. This indicates the effectiveness of the formula in managing weight, enhancing gut health, modulating immune and metabolic diseases and relieving anxiety. This research won a Silver Medal at the 2022 International Exhibition of Inventions Geneva and its application for health benefits has entered patent substantive examination stage. Making use of the thickening, emulsifying and stabilising properties of AkkMore™, the team has developed Cream Mate, an AkkMore™-based cream substitute. Cream Mate can be used in conjunction with traditional cream to reduce the amount of cream used in dessert. Not only does it decrease the fat and calorific content of food while maintaining the quality of taste and texture, but it also significantly extends the shelf life of cream-based products. In the long run, this could lead to reduced consumption of dairy products and food waste, reducing carbon emissions and profitability of production. Dr Chang stated, “This collaboration is testament to the successful translation of a research outcome. Moving forward, we will further explore the application of AkkMore™ formula in innovative health foods and put greater efforts into identification of mushroom strains with better functions and standardisation of the cultivation process.” PolyU is committed to the translation of research outcomes. Dr Chang was admitted to the PolyU GBA Startup Postdoc Programme in 2019 and has been granted support from the PolyU Micro Fund. As well as beig selected for the Incu-Tech Programme of the Hong Kong Science and Technology Parks Corporation, Dr Chang has received a number of awards in entrepreneurial competitions. In 2020, she partnered with Dr Amber Chiou and Dr Jimmy JIN, Assistant Dean and Associate Professor of the Faculty of Business to establish Bo InnoHealth Biotechnology Company Limited, a start-up focusing on research into the growth mechanism of fungus and has received generous support from the PolyU Tech Launchpad Fund and multiple angel funds. Following the launch of supplement containing the AkkMore™ formula, the research team has collaborated with GREEN of Hotel ICON, the PolyU teaching and research hotel, whereby the hotel restaurant infuses Cream Mate in reduced-fat soft serve and desserts, and launch its new limited time “ForestFit Afternoon Tea With Japanese Fruit And Akkmore™”. Hotel ICON has commissioned a laboratory to test the nutritional components of soft serve in two formulae. The test showed that the total fat content of soft serve with AkkMore™ Cream Mate was less than 3% and was reduced by more than 80% when comparing with regular soft serve, and the total energy was also reduced by more than half.

PolyU research reveals major healthcare and communication challenges for migrant domestic workers in Hong Kong

Migrant domestic workers support many Hong Kong working families in childcare and household duties but their own personal needs seldom receive significant attention. The Department of English and Communication at The Hong Kong Polytechnic University (PolyU) has conducted research into the health and other structural issues faced by migrant domestic workers in Hong Kong, especially during the COVID-19 pandemic. Findings reveal that health literacy and access to information and facilities are crucial to their well-being. The researchers have interviewed more than 700 Filipino and Indonesian migrant domestic workers and surveyed more than 400 to investigate their life stories and well-being in Hong Kong, covering topics from narratives about their (traumatic) experiences, health literacy and healthcare needs to their communication networks. In view of the increasing number of workers driven by growing demand for domestic elderly care in Hong Kong, these studies aimed to highlight the significance of cultivating favourable conditions for workers. Prof. Hans LADEGAARD, Professor of the Department of English and Communication at PolyU, said, “Our research shows that Indonesian workers, in particular, face marginalisation and isolation due to language and communication problems and a lack of awareness of their rights. Many took only a three-week Cantonese course before arrival, which clearly does not guarantee their Cantonese proficiency, while most of them are also unable to speak English. Many workers even do not know it is illegal to be paid under the minimum wage or that they are entitled to have 24 hours off once a week. Therefore, it is crucial to prioritise efforts to provide language learning support and to educate these workers about their rights.” Inadequate access to health facilities and information is one major challenge facing these workers. According to Prof. Ladegaard’s research, when the COVID-19 pandemic-induced loneliness, isolation and homesickness put them at higher risk of experiencing depression and anxiety, they only had limited access to support. To address the issue, the team advised that health campaigns be conducted in a language that the workers can understand and that accessible channels such as social media are mobilised for promotion. The research also indicated utilising cartoons and storytelling to be more effective in communicating with migrant populations. Another research study, led by Dr Jeffry OKTAVIANUS, Assistant Professor of the Department of English and Communication, found that community storytelling networks, including interpersonal relationships, community organisations and media outlets, played an essential role in supporting the migrant domestic workers in coping during the pandemic. His research has been published in the journal Health Communication. The study revealed that many workers could not obtain knowledge about effective preventive measures during the pandemic, due to the absence of reliable and accurate information in their native language. Interaction with workers’ communities on social media thus became their major source of informational and emotional support. However, workers were also exposed to fake news through interpersonal networks, which led to adverse effects, such as having a negative psychological impact. Dr Oktavianus remarked, “These networks provide crucial support, but also spread misinformation, creating both opportunities and challenges for empowering marginalised communities.” The research further highlighted the potential of community organisations in debunking hoaxes by disseminating credible news, thereby eliminating uncertainty, refuting misinformation and aiding in understanding the chaotic situation. In this regard, health campaigns are encouraged to utilise community-based storytellers, such as Indonesian organisations or ethnic media, to communicate public health information. Meanwhile, improving digital literacy is also important for helping foreign workers distinguish fake news from real. While the Philippines now has one of the highest breast cancer diagnosis rates in Asia, there is also an increasing number of Filipino workers diagnosed with breast cancer in Hong Kong. Dr Margo TURNBULL, Assistant Professor of the Department of English and Communication, led a research team focusing on the health literacy needs of migrant domestic workers. Published in the journal Quality Health Research, the research study provides a critical examination of how breast cancer and migration impact the lives of these workers. This study again emphasised the importance of health campaigns in workers’ native language and of their access to health facilities, particularly on Sundays, enabling them to receive timely diagnoses and assistance. Dr Turnbull added, “Improving language and communication skills can also increase workers’ effective utilisation of medical resources, alleviate the psychological impacts of having cancer and enhance their confidence in advocating for their healthcare needs.” Currently, Dr Turnbull is working with a cancer support group to co-develop multilingual communication resources that can be used by migrant domestic workers to share information about their diagnosis and care needs with their employers, families and doctors. In light of the structural issues uncovered by the studies, a symposium, “Migrant Worker Lives Matter”, organised by the Department of English and Communication in collaboration with two local migrant worker NGOs, PathFinders and Mission for Migrant Workers, will be held at the PolyU campus on 24 May. The event aims to address the challenges faced by migrant domestic workers and explore ways for Hong Kong to become a more inclusive society.

PolyU study reveals effectiveness of GBGI infrastructure in mitigating urban heat, proposing nine-stage framework for development of a sustainable city

Primarily due to the impact of urbanisation and global warming, urban heatwaves have become a challenging issue worldwide, with Hong Kong persistently experiencing record-breaking high-temperature days. Mitigating urban heat through green and blue infrastructures is essential for creating a sustainable environment. Prof. Hai GUO, Professor of the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University (PolyU) and global researchers have conducted a first-of-its-kind study on the effectiveness of green interventions in cooling urban heat across various regions that can assist policymakers in prioritising effective interventions to develop sustainable cities. The study findings have been published in the international interdisciplinary journal The Innovation. Globally, the most efficient air cooling was observed in botanical gardens, wetlands, green walls, street trees and vegetated balconies. In light of this, the research team conducted a global review of the effectiveness of green-blue-grey infrastructure (GBGI) in air cooling. GBGI refers to green infrastructures that encompass naturally vegetation-based elements like trees, grass and hedges; blue infrastructures are related to water-based features like pools, lakes and rivers; and grey infrastructures comprise engineered structures including green walls, green facades and roofs. The Study revealed regional and city-specific variations in the effectiveness of GBGI for mitigating urban heat. In Europe, Asia, North America and Australia, the overall cooling effect of GBGI is up to 18.9°C, 17.7°C, 12°C and 9.63°C respectively. In addition, the implementation of green and blue infrastructures has proven to be highly effective in lowering air temperatures globally. While green infrastructures can regulate urban heat through evaporation, transpiration, shading and thermal insulation, blue infrastructures absorb heat and cool the surrounding area through evaporation. In Asian cities, constructed grey infrastructures, especially roof gardens and pergolas, are found to be the most effective for urban cooling. Roof gardens in Singapore achieved the most significant temperature reduction of 17.7°C. Pergolas and green roofs in Japan and South Korea also had substantial impact, resulting in cooling temperatures by 16.2°C and 10.8°C, respectively. Linearly planted hedges and street trees contributed to lowering temperatures by up to 10.8°C. Authorities are advised to plant more street trees, not only for their impressive cooling efficiency but also for their substantial potential to create other positive environmental impacts. The Study also showed notable effects of various GBGI features in mitigating urban heat in Mainland China cities. The most effective means include botanical gardens, wetlands, green walls and attenuation ponds which exhibited temperature reductions of up to 10°C, 9.27°C, 8°C and 7°C respectively. Although the cooling effect ranges are generally similar in the north and south of China, there is variability within the same region. For example, in Beijing, botanical garden could result in up to 10°C temperature decrease while that in Shaanxi province only contributed to 2.7°C. In Hong Kong, parks, green roofs and golf courses were found to play substantial roles in cooling urban heat, resulting in temperature reductions of 4.9°C, 4.9°C and 4.2°C respectively. A “Shining City Project” was proposed by the Hong Kong government in last year’s Policy Address to enhance urban green space. This initiative includes the greening of riverbanks to turn them into flower viewing points and the extensive planting of trees in government venues and at roundabouts on major roads. Prof. Guo said, “With their distinctive location and natural environment, the types of GBGI in Hong Kong are unique. The city features a network of oceans, rivers, wetlands and reservoirs, with remarkable vegetation cover, encompassing approximately 70% of its land area of which country parks occupy around 40%, and possesses a precious natural asset in the Victoria Harbour. Meanwhile, the Government actively promotes GBGI in new development areas and the adoption of green building design in new government projects. These forward-looking initiatives highlight Hong Kong’s dedication to sustainable and resilient urban development.” Globally, the types of GBGI vary significantly across continents due to diverse regional contexts, climate conditions and urban planning priorities. The Study’s GBGI heat mitigation inventory can assist policymakers and urban planners in prioritising effective interventions to reduce the risk of urban overheating and promote community resilience. At this point, the research team has introduced a nine-stage framework to facilitate the implementation of GBGI that outlines stages of stakeholder engagement, feasibility studies, design, policy development, implementation, monitoring, evaluation, and eventual upscaling and replication. Prof. Guo emphasised, “This framework serves as a strategic roadmap, optimising GBGI implementation to maximise benefits. Policymakers should conduct thorough investigation and planning tailored to the specific context and needs of their cities. In Asia, the extensive development of GBGI is a response to challenges posed by rapid urbanisation and cultural preferences that prioritise green areas for community activities, together with environmental goals focused on biodiversity conservation, improved air quality and mitigation of the urban heat island effect. It is crucial for future GBGI implementation to adopt a holistic approach, optimising their multifunctional benefits to effectively address sustainability goals.”
