Bank of Korea Conducts Successful CBDC Pilot Test with Financial InstitutionsThe Bank of Korea (BOK) announced yesterday in a press release that its central bank digital currency (CBDC) pilot program operated successfully in a practical setting involving multiple financial institutions.Testing environmentsPreviously, the CBDC system was tested in an isolated cloud environment. In this recent test, the system was installed on the servers of various financial institutions over a five-month period to evaluate its performance.The 1.2 billion KRW ($905,000) project included the participation of six companies, such as Kakao’s Krust Universe, KakaoBank, and KakaoPay, as well as 14 banks and the Korea Financial Telecommunications and Clearings Institute. Kookmin, Shinhan, and Woori were among the participating banks.Four scenariosThe BOK and financial institutions tested the system’s performance under four scenarios: increasing transaction requests per second, increasing the number of active users, reducing the transaction queue size, and adjusting the block generation time ratio.The increase in transaction requests led to a 10% decrease in transactions per second (TPS), from 2,100 TPS to 1,900 TPS, compared to the single cloud environment test. This result is still deemed acceptable, as the highest TPS recorded in the current small payment infrastructure network is 1,200, which occurs on paydays and other high-transaction days.Issues such as slower response times arose with higher transaction request volumes but were resolved by enlarging the transaction queue size and increasing the block formation time proportion in the block generation process. The block generation process involves two stages: block formation, where transactions are recorded, and block validation, where transactions are verified.Greater stabilityThe test demonstrated that transaction errors at individual institutions did not affect others, suggesting that a distributed ledger system offers greater management stability than a centralized system. However, institutional officers cited challenges in problem-solving and communication when using the distributed ledger system.The BOK plans to involve more institutions in ongoing experiments this year, supporting them in testing their smart contracts on the CBDC pilot system.Photo by Bundo Kim on Unsplash

Upbit Accidentally Accepts Counterfeit APT Tokens, Initiates Retrieval EffortsUpbit, South Korea’s largest cryptocurrency exchange, is reported to have accepted deposits of counterfeit Aptos (APT) tokens, mistaking them for their legitimate counterparts. The exchange has been reaching out to the sellers of these tokens by phone, requesting their recovery. This news has been circulating in several online crypto communities since the afternoon of September 24 (Korea Standard Time).Photo by Kenny Eliason on UnsplashUpbit’s responsesOn September 24 at 15:47 KST, Upbit announced a temporary suspension of deposit and withdrawal services for APT due to maintenance on the APT wallet. Following this, at 22:32 KST on the same day, Upbit explained that system maintenance was undertaken after identifying an unusual attempt linked to APT deposits. The crypto exchange went on to announce that the deposit and withdrawal services for APT would resume at 23:00 KST on the same day.DeFi degenerates’ insightsIn relation to this incident, Definalist, a group of DeFi degenerates based in Korea, shared insights on X (formerly Twitter). The group stated: “It seems that during the process of reflecting $APT coin deposits, there was a failure to check the type arguments, and all same functions transfers were recognized as the same APT native token. … If all APT ecosystem tokens were sent to Upbit’s wallet, they would have been mistakenly treated as APT native coins.”Decimal place differenceDefinalist also remarked on the fortunate nature of the counterfeit APT token having six decimal places, in contrast to the authentic APT token’s eight. They noted that if the deceptive token had mirrored the genuine token’s decimal places, the market disruption could have amplified a hundredfold. Meanwhile, the value of the counterfeit APT tokens deposited into Upbit is estimated to be about KRW 20 million (approximately $15,000).

KuCoin CEO: Privacy Not a Key Bitcoin FeatureJohnny Lyu, the CEO of Seychelles-headquartered cryptocurrency exchange KuCoin, recently shared his perspective on the role of privacy in Bitcoin, maintaining that privacy isn’t the primary feature of the leading digital asset that many believe it to be.Photo by Karolina Grabowska on PexelsUnit of exchange is coreIn an interview with Cointelegraph earlier this week, Lyu expressed his belief that privacy is not the core feature of Bitcoin. He argued that the primary benefit of Bitcoin lies in its function as a unit of exchange, enabling users to hedge against recessions.Lyu drew a connection between the creation of Bitcoin and the 2008 financial crisis, which was triggered by the subprime mortgage crisis in the United States. According to him, these events served as the catalyst for the birth of Bitcoin. However, he made it clear that privacy is just one of the features offered by the cryptocurrency.KYC safeguarding customer fundsAddressing concerns about the increasingly stringent Know Your Customer (KYC) checks being implemented by KuCoin, Lyu emphasized the importance of these measures in safeguarding user funds. While some individuals argue that stringent KYC practices compromise privacy, the CEO believes that they enhance security. He explained that KYC procedures protect users’ assets by establishing ownership and enabling asset tracking in the event of theft.As the cryptocurrency industry continues to expand and interact with the physical world, compliance becomes crucial. Lyu expressed his belief that KYC checks are an inevitable and healthy stage in the development cycle of cryptocurrencies. Compliance measures contribute to the industry’s long-term stability and promote user confidence.New restrictionsKuCoin recently announced that starting from July 15, 2023, mandatory KYC checks will be implemented for all new users. This means that without completing the KYC process, new users will be unable to access KuCoin’s products and services. Existing users who have not undergone KYC will still be able to trade but will face restrictions on depositing new funds.Lyu acknowledged that these new KYC restrictions may impact KuCoin’s trading volumes in the short term, as some customers may choose to leave. However, the exchange remains optimistic about the long-term benefits of compliance. The CEO expressed confidence that increased compliance will attract more secure funds and users to the industry, ultimately enhancing the overall security and integrity of the ecosystem.KuCoin currently boasts 27 million users, reflecting a 35% increase compared to the previous year. Following the announcement of the KYC upgrades, the exchange experienced a notable uptick in trading volumes, with figures rising from around $540 million to over $660 million at the time of writing, according to CoinGecko data.The introduction of mandatory KYC checks is seen as a necessary step to enhance user security and protect their assets. Although short-term effects on trading volumes are anticipated, the exchange remains optimistic about the long-term benefits of compliance measures for the entire industry.
