Energy Theft Results in Crypto Mining Operation Shutdown in BorneoAuthorities in Miri, a city on the island of Borneo in Malaysia, swiftly responded to a tip-off from the public, leading to the successful shutdown of an illegal cryptocurrency mining operation.According to local news source, The Borneo Post, during a well-executed raid, 34 mining servers were confiscated, all of which were illicitly drawing power through cable tapping.Photo by Muhammad Faiz Zulkeflee on UnsplashEnergy thieves turn to miningWhile Borneo offers some of the lowest energy prices in Malaysia, it continues to struggle with the problem of energy theft. That issue has been highlighted via a recent utility announcement. Sarawak Energy, the local energy provider, estimated that the criminal operation caused losses of approximately 6,000 Malaysian ringgits ($1,300) worth of stolen electricity each month.The rise of the Bitcoin mining industry in 2023 has brought about record-high network hash rates and network difficulty. While the growth of miners generally signifies the robustness of the Bitcoin network, smaller operators without the economies of scale enjoyed by larger corporations face challenges.One such challenge is energy generation to power their mining servers. In pursuit of higher profit potential with lower electricity rates, illegal mining operators are drawn to stealing electricity from the grid. By eliminating energy expenses, these illicit miners can accumulate profits and offset equipment costs.Fourth recent instanceThe recent incident marks the fourth major operation in Senadin, where Miri is located, where authorities have cracked down on power theft cases related to cryptocurrency mining in 2023. So far, over 137 Bitcoin mining servers have been seized during these operations.On the other side of the spectrum, legitimate crypto mining companies are actively securing funding to support their mining projects. Riot Platforms, for instance, invested a substantial $162.9 million to acquire 33,280 state-of-the-art equipment from MicroBT, a leading producer of mining machinery.In another example, Coinbase extended a $50 million credit line to Canadian cryptocurrency firm Hut 8 Mining, facilitating its operations. Furthermore, Volcano Energy, a public-private partnership in El Salvador, secured an initial funding of $250 million for its ambitious Bitcoin mining venture.Appropriate mining activityThe spate of recent instances of illegal mining in Borneo acts as a reminder of the importance of regulatory compliance and adherence to the law within the cryptocurrency industry. While the allure of lucrative profits may tempt some to engage in illegal activities, the consequences can be severe. Mining can be a positive societal force when applied within appropriate circumstances.A move by the President of Kyrgyzstan last week to harness crypto mining in order to utilize energy that is otherwise being wasted at the central Asian country’s Kambar-Ata-2 hydropower plant serves as a recent example of a positive use case for the activity.In Texas in the United States, crypto miners are collaborating with those that manage the local energy grid, turning off miners at times when the state is on the brink of suffering blackouts.As the crypto mining landscape continues to evolve, it is essential for both authorities and legitimate operators to work together in finding sustainable solutions that ensure the industry’s growth while maintaining the integrity of the energy infrastructure.

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

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.
