Naver confirms ad takedowns for unregistered crypto platforms as rules are refined

Public Confidence in Crypto Wanes in Hong Kong Amid JPEX ScandalThe development of cryptocurrency in Hong Kong has been dented in terms of public sentiment following the JPEX cryptocurrency exchange scandal, according to a recent survey conducted by the Hong Kong University of Science and Technology’s (HKUST) business school.Photo by Alex Plesovskich on UnsplashA two-phase survey methodologyThe survey, the preliminary results of which were disclosed by the business school on Tuesday, aimed to gauge how public attitudes toward virtual assets had been affected by the JPEX scandal, which rocked the crypto community within the Chinese autonomous territory.While the survey is set to conclude on October 20, the preliminary findings have already revealed a noteworthy shift in public perception. Notably, 41% of respondents expressed a preference not to hold virtual assets, marking a 12-percentage-point increase from the earlier study conducted in May.Moreover, only 20% of respondents indicated a desire to hold virtual assets in the future, reflecting a five-percentage-point decrease compared to the previous survey. These findings suggest a growing skepticism among Hong Kong’s populace regarding the cryptocurrency industry.Post-JPEX public sentimentThe initial survey involved 5,700 participants aged 18 and above and was conducted between April 24 and May 23. Phase two of the survey commenced on September 28, approximately 11 days after the allegations against JPEX came to light. The results were compared to a similar survey conducted between April and May to assess the evolving sentiment. Between September 28 and October 5, phase two of the survey had compiled responses from 2,200 individuals.HKUST acknowledged that the second survey occurred in the “aftermath of an alleged financial fraud” involving a cryptocurrency platform but refrained from directly naming JPEX in the report.Professor Allen Huang, Associate Dean of HKUST’s business school, attributed the shift in sentiment to the recent financial scandal, which thrust the cryptocurrency industry into the spotlight. This heightened attention has led to a “more conservative investment appetite” among the public. He emphasized the need for greater educational initiatives to enhance public awareness and understanding of the risks and potential of this emerging field.HKUST’s business school stated that the survey’s primary objective was to assess the attitudes and viewpoints of Hong Kong’s residents regarding virtual asset investments, considering their experiences, intentions, and the regulatory safeguards in place.JPEX falloutThe JPEX scandal, which allegedly involved a $166 million fraud scheme, unfolded over several months before Hong Kong authorities publicly announced their investigation into the exchange. It forced local regulators to reassess the soundness of crypto trading-related regulatory measures applied within the Chinese autonomous territory.That reassessment led to regulators concluding that efforts needed to be intensified to combat unregulated platforms operating within Hong Kong. In response to the JPEX saga, the Hong Kong Police Force and the Securities and Futures Commission (SFC) established a cryptocurrency-focused working group earlier this month to combat illicit activities on cryptocurrency exchanges.The evolving sentiment in Hong Kong reflects the broader challenges and concerns surrounding the cryptocurrency industry. As regulatory scrutiny increases and major incidents like the JPEX scandal come to light, it’s clear that fostering public trust and understanding is a pressing priority for crypto businesses and the broader crypto community.

AndUs to implement ZK rollups on Its public permissionless blockchainAndUs, the South Korean developer of public permissionless blockchain Anduschain, announced on Wednesday (local time) that it is preparing to implement zero-knowledge (ZK) rollup technology into its blockchain to enhance scalability and security. ZK rollups are layer-2 scaling solutions that move transactions off-chain to increase throughput on the Ethereum mainnet.Photo by Shubham Dhage on UnsplashPerspective on ZK rollupsMany Korean projects are focused on developing various layer-2 solutions. Against this backdrop, Park Sung-jun, CEO of AndUs and a Ph.D. in cryptography, believes ZK rollups will eventually surpass the currently popular optimistic rollups as the mainstream technology. Although both ZK and optimistic rollups improve scalability by processing transactions off-chain, they differ in their approaches: ZK rollups rely on validity proofs, while optimistic rollups utilize fraud proofs.Introduction next yearHolding this belief, AndUs has formulated a ZK rollup implementation plan and has begun its development, aiming to introduce it by next year. Park commented that this upgrade will significantly improve the blockchain’s speed and expressed plans to offer the world’s lowest gas fees.AndUs claims that their DEB consensus algorithm focuses on fairness, enabling nodes to engage in mining without preconditions. Furthermore, Anduschain’s ZK rollups will be fully compatible with Ethereum virtual machines (EVMs), facilitating a seamless transition of decentralized applications (dApps). The cryptocurrency used on Anduschain is named DEB, and it is currently listed on cryptocurrency exchanges ProBit Global and MEXC, according to CoinMarketCap.AndUs has been participating in the Tech Incubator Program for Startups (TIPS) program, which is led by private investments under the guidance of the Korean Ministry of SMEs and Startups.

Hacking Attempts on Upbit Reach 160,000 in First Half of the YearThere have been approximately 160,000 hacking attempts on Upbit, Korea’s largest cryptocurrency exchange, in the first half of this year alone, according to a report submitted by Upbit’s operator Dunamu to lawmaker Park Sung-joong of the National Assembly’s Science, ICT, Broadcasting, and Communications Committee.“Cryptocurrency hacking incidents are increasing both domestically and internationally, and hacking attacks on exchanges such as Upbit, which have daily trading volumes exceeding KRW 2 trillion, are a serious issue,” Park said.Photo by Clint Patterson on UnsplashAn uptick in hacking attemptsThe data revealed that the number of cyber breach attempts in the first half of the year totaled 159,061–2.17 times higher than the number of attempts in the first half of last year, which stood at 73,249.Hacking attempts on Upbit have been steadily increasing in recent years, from 8,356 in the second half of 2020 to 34,687 and 63,912 in the first and second half of 2021, respectively. In the first half of last year, there were 73,249, and 87,242 in the second half. Notably, the exchange suffered losses of approximately KRW 58 billion (approximately $43 million) from a hacking attack in 2019.Ramping up securitySubsequently, Dunamu has taken action to enhance security by managing over 70% of its assets in cold wallets and operating hot wallets in a distributed structure instead of a singular one. Hot wallets refer to online crypto wallets, whereas cold wallets are crypto wallets that are offline and disconnected from the internet. Hot wallets offer the advantage of direct deposits and withdrawals, but they have weaker security levels — most known exchange hacks have thus occurred through this medium. On the other hand, cold wallets store private keys on offline sources like external hard drives and portable storage devices, making real-time trading difficult but providing better security and stability.“We have taken various preventive measures since the hacking incident in 2019, such as operating hot wallets in a distributed manner. There have not been any successful cyber breaches to date,” Upbit said.Regarding the role of the Ministry of Science and ICT in managing and overseeing crypto hacking incidents, Park pointed out that this still remains ambiguous. “The Ministry should conduct large-scale white-hat hacking tests and security assessments for crypto exchanges that are frequently faced with hacking attempts, as well as for hospitals and subway systems that manage large amounts of personal information,” he said.
