Mixin Network Suspends Services Amid $200 Million HackOn Monday, Mixin Network, a decentralized peer-to-peer network whose project team is based in Hong Kong, officially confirmed a substantial security breach that resulted in the loss of approximately $200 million in crypto assets from its mainnet.Photo by GuerrillaBuzz on UnsplashSeptember 23 hackThis incident, disclosed via an X (formerly Twitter) post, prompted the immediate suspension of all deposit and withdrawal services on Mixin Network until further notice.The project team outlined that the hack occurred on September 23, exposing vulnerabilities that allowed malicious actors to compromise the database of a third-party cloud service provider. Mixin Network has taken action to address the situation, enlisting the expertise of Singapore-headquartered blockchain security investigator SlowMist and the support of Google to conduct a thorough investigation and formulate a recovery plan.At the time of the breach, Mixin Network’s holdings included $94.48 million in Ether, $23.55 million in Dai, and $23.3 million in Bitcoin, as reported in an independent investigation by PeckShield. The total value of assets affected amounted to $141.32 million.Cyvers, an Israeli Web3 security firm, has also been looking into the matter on Monday. In a social media post, the firm stated:”Our internal investigation has uncovered suspicious funding transactions involving @MixinKernel hacker addresses. Two of hacker addresses received 51 $ETH from 0x1795F0eBDa5A836aE63F28CE546E72de069A8bd2 who was interacted with @HuobiGlobal and @binance.”The firm goes on to call on Binance and its CEO Changpeng Zhao (CZ) and Huobi to help identify the wallet address in question.Halting withdrawalsIn response to the security breach, Mixin Network has temporarily halted all deposits and withdrawals on its platform. These services will only resume once the vulnerabilities have been identified and fully resolved. On X, the project stated:”Deposit and withdrawal services on Mixin Network have been temporarily suspended. After discussion and consensus among all nodes, these services will be reopened once the vulnerabilities are confirmed and fixed. During this period, transfers are not affected.”Details regarding the plans to recover the lost assets for affected users have yet to be announced.Despite initial promises that Mixin Network’s Founder, Feng Xiaodong, would address the incident in a public Mandarin live stream on September 25, links to the live stream were not provided on the official social media channels or the website mixin.network.The incident has garnered criticism on the basis of a lack of decentralization. One commentator stated:”Some of those blockchain protocols are so decentralized that when their cloud database is hacked, coins are also gone.”Ongoing hacksThis security breach on Mixin Network is the latest in a series of high-profile crypto-related incidents. Ethereum Co-Founder Vitalik Buterin recently fell victim to a SIM swap attack, which resulted in the compromise of his X (formerly Twitter) account.In a statement, Buterin revealed that the hackers had successfully executed a SIM swap, a type of attack that targets the victim’s mobile phone number to gain unauthorized access to various online accounts, including social media, banking, and cryptocurrency platforms.The repercussions of the Mixin Network hack underscore the ongoing challenges faced by the crypto industry in ensuring the security and protection of digital assets. As investigations continue, affected users await further developments and the eventual resumption of deposit and withdrawal services.

Over the years, we have put a lot of love and passion into our brand and product.”She emphasized that this rebranding effort, beginning in Singapore, will extend to Europe and the United States in the coming months, ensuring consistency across key operational jurisdictions. Despite the name change, OKX maintains that customers can expect the same high-quality services within the same regulatory framework under the new brand. Providing the rationale for the change, Hong Fang went on to state:”We also believe it’s time for a change. Rebranding to OKX in our key operational jurisdictions will be great for our customers and business. I’m very excited about what to come next.”Previous rebranding activityFang also revealed that OK Group has already sunsetted the “Okcoin” brand and product in several regions, including Latin America, the Middle East and North Africa, South Asia, Hong Kong, and others.

OKEx, founded by OK Group CEO Star Xu in 2017, had played a significant part in terms of innovation in the cryptocurrency space during that time.OK Group’s decision to rebrand its crypto ventures under the unified name “OKX” signifies a strategic shift toward creating a more cohesive and streamlined brand presence in the global crypto market. The transition stands out as yet another iteration in the development of global crypto platforms within an ever-changing crypto ecosystem. As Hong Fang put it, “Okcoin was started almost 10 years ago.” . . . “We have been unequivocally investing in our Okcoin team and infrastructure ever since.”

OKX Ventures, the investment wing of the Seychelles-based cryptocurrency exchange OKX, has disclosed a strategic A-round investment in Polyhedra Network. Details of the investment have been outlined through a press release published via PRNewswire on Tuesday. Specializing in the creation of Web3 infrastructure, Polyhedra Network places a premium on interoperability, scalability and privacy, leveraging advanced zero-knowledge (ZK) proof technology.Photo by Precondo CA on UnsplashInteroperability with privacyA ZK proof provides the ability for one party to cryptographically prove to another party that it possesses a certain piece of information without having to reveal the actual underlying information to the other party. Central to Polyhedra Network's product offering is its zkBridge protocol, a system facilitating trustless and efficient cross-chain infrastructure for both layer-1 and layer-2 interoperability. The protocol empowers the receiving chain to verify specific state transitions on the sending chain. This approach ensures robust security without external assumptions, effectively reducing the costs associated with on-chain verification. Polyhedra Network made an initial impact in 2023 with the launch of the "zkBridge Mainnet Alpha." That product enabled interoperability over 20 layer-1 and layer-2 blockchains, including well-known networks such as Bitcoin, Ethereum, BNB Chain and Arbitrum. Distributed proof systemThe innovative strides of Polyhedra Network, which was founded in the United States by James Zhang, Tiancheng Xie and Nikhil Shah, continued in 2023 with the introduction of deVirgo, a novel distributed proof system expediting proof generation. The deVirgo protocol also incorporates recursive proofs which trim on-chain proof verification costs associated with zkBridge. Last month, Polyhedra Network unveiled its Bitcoin messaging protocol with zkBridge, ushering trustless interoperability into the Bitcoin ecosystem through the use of ZK-proof technology. Asian backingBy championing entrepreneurs contributing to the blockchain industry's advancement, OKX Ventures is helping to build innovative companies, bringing global resources and historical experience to the forefront of blockchain projects. It is one of many Asia-centric venture firms to do so. Polyhedra has secured backing from Hong Kong’s Animoca Brands and HashKey Group, Singapore’s UOB Venture Management, NGC Ventures, Signum Capital and Foresight Ventures, alongside KuCoin Ventures. In an initial funding round in February 2023, the UC Berkeley team attracted $10 million in funding. By April, a pre-Series A round had raised a further $15 million. Dora Yue, the founder of OKX Ventures, expressed their honor in participating in the investment in Polyhedra Network's interoperability infrastructure. Yue lauded the creativity demonstrated by Polyhedra Network's team in developing advanced ZK-proof mechanisms, emphasizing the balance achieved between ZK interoperability and scalability. OKX Ventures, with an initial capital commitment of $100 million, is committed to supporting Polyhedra Network's vision of seamlessly connecting the Web2 and Web3 worlds, aiming to attract a more extensive user base to the industry. As the investment arm of the global crypto exchange platform, it dedicates itself to exploring top-tier blockchain projects on a global scale. Its focus is on fostering cutting-edge blockchain technology innovation, aspiring to support the healthy development of the global blockchain space and investing in long-term structural value.
