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.

Bank of Japan Publishes Results of CBDC PoCThe Bank of Japan (BoJ) recently concluded the second phase of its central bank digital currency (CBDC) proof of concept (PoC) project, which began in April. The results of this phase were published on Monday, and they shed light on key aspects such as the comparison between account-based and token-based CBDCs and the management of holding limits for users with multiple accounts.Photo by Manuel Cosentino on UnsplashToken-based CBDCsThe experiments conducted by the central bank covered a wide range of topics. Among the most intriguing findings were the advantages and disadvantages of token-based CBDCs and how to effectively impose holding limits for users with multiple CBDC balances.Token-based CBDCs have garnered interest from various central banks, with some adopting the UTXO token model used by Bitcoin without the use of a distributed ledger. A UTXO or unspent transaction output, defines where a blockchain transaction starts and finishes. The Bank of Japan explored this model and analyzed its pros and cons.In the initial proof of concept, both account-based and token-based CBDCs were examined, considering scenarios where the central bank managed the ledger or shared it with intermediaries like banks. In the token-based model, fixed token denominations were used, similar to physical cash in countries like India, and a centralized ledger was employed. However, in the recent phase, the central bank utilized flexible value tokens similar to UTXO and shared ledger functions with intermediaries.The Bank of Japan favored the flexible value token model due to its ability to handle multiple requests simultaneously. However, it acknowledged that this model may require more technical resources compared to the account-based approach. Challenges may arise when implementing additional functions, such as holding limits, while maintaining optimal performance. The European Central Bank (ECB) also noted in a recent report that most payment providers are accustomed to account-based payments and would incur costs to adapt to token-based systems.Another significant aspect explored by the BoJ was how to impose holding limits when users have multiple CBDC balances through different intermediaries. The challenge lies in determining if the overall holding limit has been breached without compromising user privacy.Homomorphic encryptionOne possible solution discussed in the report is the use of homomorphic encryption, which enables computations to be performed on encrypted data without it first needing to be decrypted. That allows for the necessary checks without intermediaries accessing the specific data being checked. Although this solution may slightly increase processing time, it could introduce a higher risk of data inconsistencies.Alternatively, a simpler approach proposed by the central bank is to establish a per-account holding limit and a limit on the number of accounts a single user can hold, rather than imposing global limits. Ideally, users with multiple accounts would have a higher per-account holding limit compared to those with fewer accounts.Phase 3 underwayWith the next pilot phase already underway, the BoJ aims to test the end-to-end process flow and identify challenges related to integrating with external systems. Additionally, they are creating a CBDC Forum to gather input from the private sector, ensuring a collaborative approach to CBDC development.While investigation and research into CBDCs continues, the BoJ has said that it will make a final decision on CBDC implementation by 2026.

Korea to Tighten Scrutiny of Crypto Exchange Shareholders Amid Rising ConcernsSouth Korea’s financial regulator is stepping up efforts to evaluate the qualifications of majority shareholders of cryptocurrency exchanges, according to a report by local news outlet Newsis. This initiative follows instances where majority shareholders of local exchanges, including Bithumb, found themselves embroiled in criminal proceedings. Drawing parallels with the banking sector, the regulator is scrutinizing the credentials of majority shareholders to ensure compliance and integrity within the cryptocurrency exchange landscape.Photo by Terrence Low on UnsplashRevamping reporting requirementsThe Financial Intelligence Unit (FIU) under the Financial Services Commission recently set up a task force to revamp the reporting requirements for crypto exchanges.The upcoming requirements are anticipated to be integrated into the reporting forms that cryptocurrency exchanges must complete, starting in October of next year. Essentially, these stipulations will determine whether existing exchanges, such as Upbit, Bithumb, and Coinone, can sustain their operations in the future.Periodic evaluationAccording to the Enforcement Decree of the Financial Transaction Reports Act, all virtual asset service providers (VASPs), including exchanges, are mandated to submit a renewal report every three years. Upbit, having been the first to submit its initial report in October 2021, will join other crypto exchanges in updating their reports in October 2024.A majority shareholder qualification assessment is a process in which the government periodically checks whether majority shareholders have the necessary qualifications to operate a financial company. Through this process, the FIU aims to curb potential illicit activities by majority shareholders, who hold significant sway over cryptocurrency exchange operations, thereby mitigating any potential harm to the users.Regulatory grey areaThis measure emerged from concerns that majority shareholders of exchanges have existed in a regulatory grey area. In fact, under the Financial Transaction Reports Act, only exchange representatives and registered officers are required to report and undergo examination when declaring VASPs. This leaves the actual owners and controllers — the majority shareholders — unidentified and unexamined.The current circumstances involving VASPs are markedly different and more concerning compared to other financial sectors. In the banking sector, restrictions are placed on share ownership and voting rights if majority shareholders have breached financial laws or if they are capital entities forbidden from owning a bank. Similarly, online peer-to-peer lenders and large lenders are also under obligation to have their majority shareholders scrutinized, as they fall under analogous regulations.Fraud and manipulation allegationsThe heightened scrutiny is also thought to have been sparked by recent allegations of fraud and market manipulation involving some majority shareholders of Korean exchanges. For instance, Mr. Kang Jong-hyun, a majority shareholder of Bithumb, is currently facing a criminal trial for allegations of fraudulent and unfair trade activities under the Capital Markets Act. Additionally, Song Chi-hyung, the majority shareholder of Upbit and chairman of Dunamu, is facing a Supreme Court trial over alleged price manipulation through wash trading.Moves to amend legislationMeanwhile, efforts are underway in the National Assembly to amend the existing legislation. Yun Chang-hyun, a lawmaker from the ruling People Power Party and a member of the National Policy Committee, has recently proposed a bill to revise the Financial Transaction Reports Act. The amendment seeks to implement a majority shareholder screening system for VASPs.The proposed amendments would obligate VASPs, including crypto exchanges, to disclose information about their majority shareholders in their reports, thereby enabling the FIU to scrutinize any past financial crimes or economic offenses committed by these majority shareholders.
