AndUs to implement ZK rollups on Its public permissionless blockchain

Japanese consumer electronics conglomerate company Sony appears to be gearing up for a cryptocurrency exchange relaunch following its acquisition of WhaleFin. That’s according to a press release published by Japanese public relations company PR Times. Last year, Sony bought Amber Group, a Singapore-headquartered digital asset and crypto financial services firm, which operates crypto exchange WhaleFin. It now appears that the company plans to revamp the local trading platform.  S.BLOX crypto exchangeAmber Group has been renamed to S.BLOX Co. A statement from WhaleFin confirmed the name change. The rebranding has occurred following the acquisition in August 2023 of Amber Group by Quetta Web, a wholly-owned subsidiary of Sony Group Corporation. It also outlined plans to upgrade the service in terms of user experience through a user interface (UI) design refresh. Furthermore, the service plans on releasing new applications going forward.  Part of the strategy is to leverage Sony Group businesses in order to further bootstrap the crypto exchange. Using this approach, the company believes that it can create new added value in cryptocurrency trading services.  The precise launch date of the renewed WhaleFin crypto exchange has yet to be announced. S.BLOX is registered with the Kanto Local Finance Bureau of the Ministry of Finance. Furthermore, it’s a member of the Japan Virtual and Crypto Assets Exchange Association (JVCEA), which oversees cryptocurrency trading within the Japanese jurisdiction from a regulatory and compliance perspective. The exchange business is understood to have a current capitalization of 1,708,179,531 yen (around $10.5 million).Photo by James Feaver on UnsplashWeb3 focusSony has made a concerted effort to expand its activity in the Web3 space. In March 2023, the company filed a patent that aims to enable players of Sony gaming products to access interactive Web3 gameplay. That application will focus on the use use of NFTs. A month earlier, Sony Network Communications, its internet provider division, partnered with the Astar blockchain development team in order to create an incubation program for startups who are working on decentralized autonomous organizations (DAOs) and NFT-based innovation. The same subsidiary partnered with Japanese blockchain firm Startale Labs last September in order to build Sony’s own public blockchain network. The CEO and founder of Startale Labs, Sota Watanabe, took to the X social media platform on July 1, clarifying that Startale’s external director will be heading up Sony’s new crypto exchange. While Sony has dipped its toe in the water previously relative to Web3 projects, this latest development will see it become more deeply involved in the crypto and Web3 space.  Amber Japan was bought out by crypto finance firm Amber Group in 2022 when it was known at that time as DeCurret. Last year, Bloomberg reported that Amber Group was working towards selling off the enterprise due to difficulties in navigating the strict regulatory environment it encountered within the Japanese market. In a related development, it emerged last month that leading Japanese crypto exchange bitFlyer had acquired FTX Japan, the Japanese subsidiary company of the failed global crypto exchange business.

Crypto.com, one of the world's largest cryptocurrency exchanges, has indefinitely delayed its service launch in South Korea after the country's financial regulators conducted an on-site inspection on the exchange. The inspection came after the country’s Financial Intelligence Unit (FIU) under the Financial Services Commission detected data that appeared to violate anti-money laundering (AML) compliance requirements from the documents submitted by Crypto.com, according to local media Segye Ilbo. This decision came just six days ahead of its planned launch, originally scheduled for April 29.  The exchange has secured a virtual asset service provider (VASP) license by acquiring the local trading platform called OkBit in June 2022. A VASP license allows a digital asset exchange to operate in Korea.  Photo by Leeloo The First on PexelMitigating ‘Kimchi Premium’ effect Crypto.com initially planned to launch a mobile app featuring cryptocurrency trading on April 29, targeting South Korean retail investors. The platform aimed to differentiate itself from other local competitors by offering crypto assets at reasonable prices, mitigating the so-called Kimchi Premium effect, as announced in a press conference on April 2. The Kimchi premium refers to relatively high crypto prices in the Korean market compared to other foreign markets, which is prevalent in Korea’s major licensed crypto exchanges. The effect often results in Korean investors buying crypto assets at higher prices than those on other global crypto exchanges such as Binance. This is likely where the concerns for AML violation come up, financial experts assume, as the platform’s strategy could facilitate arbitrage during operation.  Crypto.com remains committed to Korea launch In a statement sent to CoinDesk, a spokesperson of Crypto.com said, “Crypto.com maintains the highest Anti-money Laundering standards in the industry. We will postpone our launch and take this opportunity to make sure Korean regulators understand our thorough policies, procedures, systems and controls, which have been reviewed and approved by major jurisdictions around the world.”  The person also mentioned that South Korea is a difficult market for global crypto exchanges to enter, but still emphasized the company’s commitment to cooperating with local regulators.  “OkBit maintained approximately 900 customers at the point of acquisition by Crypto.com, and OkBit has never been cited for any AML infractions. Since the acquisition, existing OkBit customer access has been limited to withdrawals,” the spokesperson said. 

South Korea’s largest crypto exchange, Upbit, suffered a security breach on Nov. 27 that resulted in the theft of 44.5 billion won ($30.4 million) in digital assets, all taken from the exchange’s hot wallets. The stolen tokens were all Solana-based, and Upbit CEO Oh Kyoung-suk said in a statement that no users will incur losses, as the company will cover the full amount with its own reserves.Photo by FlyD on UnsplashHot-wallet breach hits 24 tokensThe exchange said in a statement that the compromised tokens were transferred to an unknown external wallet at around 7:42 p.m. UTC on Nov. 26. In total, 24 cryptocurrencies were affected, all within the Solana ecosystem. The stolen assets ranged from infrastructure tokens such as Solana (SOL) to staking-related assets like Jito (JTO), along with the stablecoin USD Coin (USDC) and memecoins including Bonk (BONK), Moodeng (MOODENG), and Official Trump (TRUMP). According to Oh, the breach was followed by an emergency security review of the affected networks and wallets. He added that all remaining assets were moved to cold storage to prevent further unauthorized transfers. Oh also said the exchange is working to trace the stolen assets and block on-chain movements wherever possible, noting that Solayer (LAYER) tokens worth 2.3 billion won ($1.6 million) have already been frozen. Upbit is also reaching out to relevant projects and institutions for assistance. This marks Upbit’s second theft case. The first took place on Nov. 27, 2019, exactly six years ago to the day, according to News1. Authorities focus on Lazarus’ involvementFinancial authorities are investigating the incident, and North Korea’s Lazarus Group is being treated as the leading suspect, the Maeil Business Newspaper reported. Lazarus is also believed to have been behind the 58 billion won ($40 million) worth of Ethereum (ETH) stolen from Upbit in 2019. A government official told the paper that the latest breach did not appear to stem from a server intrusion but may have involved a stolen administrator account, allowing the attackers to impersonate internal staff and move assets—similar to the method used in the 2019 case. Security analysts echoed that assessment. One investigator said the stolen funds moved through exchange wallets before being mixed, a pattern often linked to Lazarus. He added that mixers, which are prohibited in Financial Action Task Force (FATF)-member jurisdictions, make tracing difficult and that attackers typically route assets through countries outside that framework, further pointing to North Korea. Following the incident, Upbit suspended deposits and withdrawals for all assets and said services will resume once security is fully verified. The halt has also affected trading dynamics on the exchange, with CryptoQuant CEO Ki Young Ju noting that retail investors are fueling altcoin spikes as arbitrage bots remain offline. Dunamu, Naver set $6.8B growth planThe security crisis struck at a particularly sensitive moment for Upbit’s operator, Dunamu, overshadowing what was intended to be a celebratory corporate milestone. On that same day, Dunamu, Naver, and Naver Financial held a joint press conference to outline their global expansion strategy. Dunamu brings its blockchain and crypto infrastructure, Naver contributes its position as Korea’s dominant search engine, and Naver Financial adds its payment platform serving 34 million users. The event came after reports that Naver Financial and Dunamu had approved a merger plan through a comprehensive share swap, with the ratio set at 2.54 to 1. The three companies said they will combine their respective strengths to invest 10 trillion won ($6.8 billion) over the next five years in building an ecosystem centered on Web3 and artificial intelligence (AI).During the press conference, Naver CEO Choi Soo-yeon said no decisions have been made on a Nasdaq listing for the newly combined Naver Financial–Dunamu entity or on whether it might eventually merge with Naver, according to TechM. She said dual listings remain a matter requiring national consensus. Choi also noted that while Naver Financial is a Naver subsidiary, Dunamu is the larger partner, and a later merger between the combined entity and Naver is unlikely.
