Korean health management app leverages blockchain for iris-based solutionsIRIS, a blockchain foundation focused on healthcare, announced on Wednesday (local time) the launch of a health management app developed in collaboration with Hongbog, a South Korean provider of iris-based biometric systems. This app offers services customized to each user’s health status and lifestyle.Photo by Kalea Jerielle on UnsplashIridology-based health analysisUnlike other healthcare platforms that primarily focus on exercises, IRIS’ app offers long-term and periodic health trend analysis reports through iris photography. This approach is based on “iridology,” a concept used in traditional Korean medicine, and the app also recommends visits to specialized healthcare providers based on its findings.The app instantly analyzes a user’s biometric information through artificial intelligence once a picture of their eyes is captured with a smartphone camera. Within 15 seconds, users can view their results, based on which the app recommends personalized exercises and nutrients.This platform serves both personal disease management and prevention, and can also be utilized by public health centers for monitoring the health of local residents. Presently, it provides five health ratings for cholesterol, stress levels, and four specific organs: the brain, lungs, liver and kidneys. Future updates will optionally include information on an additional 15 organs, such as the heart, bronchi, pancreas and stomach.Blockchain-powered privacy protectionA representative from IRIS conveyed that their goal in an aging society is to assist customers in preventing serious illnesses and promoting longer, healthier lives. They emphasized that the app enables regular measurement of health indicators, aiding in disease prevention and management. The representative also mentioned that by storing sensitive healthcare information on the blockchain, the service eliminates the risk of personal data leaks.

Celebrating a Decade of Crypto in South Korea: Experts Convene to Chart the FutureThe MK Virtual Asset Conference, an event held in Seoul yesterday to celebrate the 10th anniversary of South Korea’s cryptocurrency industry, convened experts, politicians, and stakeholders to discuss the future of blockchain and digital assets.The conference was hosted by Maeil Business Newspaper and its blockchain subsidiary Mblock, and sponsored by cryptocurrency exchange Korbit, the Korean Securities Association, and the Korea Derivatives Association. It served as a valuable opportunity to evaluate the current state of the crypto market and explore solutions for pressing challenges.Photo by Ciaran O’Brien on UnsplashInevitable rise of blockchainOne of the distinguished speakers at the event highlighted the inevitable rise of blockchain technology. Kim Yong-beom, CEO of Hashed Open Research, the research arm of Seoul-based crypto venture capital firm Hashed, said, “Blockchain is the antithesis of the modern financial and capital system. While traditional finance possesses its own merits, it also carries substantial transaction fees and is confined within national boundaries. It is only natural that such a counterforce has emerged to address these issues.”He continued, “Given that traditional finance properly responds to blockchain technology’s rise and overcomes its limits, blockchain may lose its competitive edge. However, if traditional finance fails to do so, blockchain will not be easily dismissed.”CEO Kim also highlighted the third section named “Blueprint for the Future Monetary System” of the Bank of International Settlements’ 2023 Annual Economic Report, which was published in June. The report states, “The BIS Innovation Hub, in partnership with central banks around the world, stands at the forefront of experimentation with CBDCs and tokenization.” According to Kim, the traditionally conservative financial institution, which had previously been skeptical about blockchain-based distributed ledger technology, has now shifted its position to be more accepting of blockchain.Importance of institutional investorsDuring the conference, an academic underscored the importance of allowing institutional investors to enter the virtual asset space. Kang Hyoung-goo, an assistant professor in the Department of Finance at Hanyang University Business School, pointed out that the crypto market, when primarily driven by retail investors, tends to favor volatile assets over stable ones. Due to this inclination, more individual investors are attracted to exchanges where speculative trading is a frequent occurrence. This dynamic creates a vicious cycle, he explained.Defining digital assetsOn a different note, Lee Han-jin, a lawyer at Kim and Chang, one of the largest law firms in the country, emphasized the crucial need to establish a legal definition of digital assets. In Lee’s view, digital assets exist in the form of data on the blockchain, setting them apart from traditional assets. He argued that without a legal definition outlining the nature of these assets, they could potentially devolve into entities that mislead the public, lacking both legal reliability and trustworthiness.Political voicesPoliticians also took the stage to share their thoughts. Back Hye-ryun, a Democratic Party of Korea member, expressed in her congratulatory speech her commitment to protecting virtual asset users through legislation. Kim Jong-min, another lawmaker from the same party, underscored the unstoppable nature of the blockchain trend. Yun Chang-hyun, a lawmaker of the ruling People Power Party, mentioned that while Bitcoin couldn’t establish itself as a key currency in an anarchic manner, stablecoins and central bank digital currencies (CBDCs) are now positioned to fill that role.Regulatory considerationsMeanwhile, Kim So-young, Vice Chairman of the Financial Services Commission, stressed the ongoing uncertainty surrounding the societal impact of cryptocurrencies and how governments should oversee them. He emphasized that the Korean government aims to establish a balanced framework to facilitate the responsible development of digital assets. Furthermore, he highlighted the necessity of collaborating with major economies due to the global nature of virtual assets.

KISA to establish blockchain trust framework for public servicesThe Korea Internet & Security Agency (KISA) is developing a system called the Korea-Blockchain Trust Framework (K-BTF) to facilitate the development and operation of blockchain-based public services, said Lee Kang-hyo, a senior official at KISA, during the 2023 Blockchain Grand Week on Wednesday (local time).Blockchain Grand Week is an event hosted by the Ministry of Science and ICT and jointly organized by the National IT Industry Promotion Agency (NIPA), the Korea Internet and Security Agency (KISA) and the Institute of Information and Communications Technology Planning and Evaluation (IITP) to promote the value of blockchain technology in enhancing trust in the digital age.Photo by Philipp Katzenberger on UnsplashPrevious roadblocksKISA has executed over 100 blockchain pilot projects over the last five years, but only a few have been carried out due to significant costs and interoperability barriers between services. According to the agency, it costs KRW 450 million (approximately $348,000) to carry out one project. Therefore, it has shifted its focus to making development easier and supporting data interoperability between services.“Developing blockchain-based public services entails building a blockchain platform, developing services and connecting them with government legacy systems,” Lee explained. “Blockchain developer APIs are becoming standardized overseas, and we thought it was time for us to leverage such advantages as well.”Another challenge was that previous blockchain-based public or governmental services did not offer smooth user experiences (UX), often requiring the installation of separate wallets or applications with each use.Bringing cost-efficient, user-friendly public blockchain servicesTo address these issues, KISA decided to focus on three key areas for building K-BTF — cost reduction, convenient development and usability — with an overall groundwork that covers interfaces, services and security while minimizing intrusion into the private sector.Once the K-BTF is established, government agencies will be able to easily plan and operate blockchain-assisted services such as decentralized identifiers (DIDs) and non-fungible tokens (NFTs). The costs for development will be determined based on how much a given service is used instead of the original base cost of KRW 450 million.Also, public institutions tend to go through staffing changes quite often, and building services under K-BTF will enable governmental operations to run normally without any roadblocks or inconveniences caused by such changes.Lee went on to mention that although a wide array of services can be built on the framework, there will be basic requirements in terms of functionality, performance and security that must be fulfilled for a service to run on it. To verify this, the KISA established a testing and certification system that utilizes its Cloud Security Assurance Program (CSAP) certification system and the Information Security Management System (ISMS).To improve usability, the framework will require users to install only one digital wallet that stores digital forms of identification and various authentication certificates.The KISA is set to start working on the K-BTF next year. Notably, it plans to create a governance system consisting of government agencies — those that are the demand clients for the framework –, private corporations and related experts. Six core services that will employ K-BTF have already been selected after a review of 34 pilot projects proposed in 2021 and 2022 and major national blockchain projects from six overseas countries. These six services are NFTs, DIDs, data origin authentication, data history tracking, Blockchain as a Service (BaaS) and digital wallets.Lee emphasized that the goal of the K-BTF is to derive services that can be used by the public sector within regulatory and technological boundaries.
