Thailand's SEC accuses Bitkub executives of concealing a $50 million hacking loss and has filed a criminal complaint

The Securities and Exchange Commission (SEC) of Thailand has filed a criminal complaint against the cryptocurrency exchange Bitkub Online and two former directors, Sakolkorn Sakavee and Thaweesap Rawan, accusing them of submitting false financial reports between May and October 2021. The case has been handed over to the Economic Crime Suppression Division (ECD) of Thailand for investigation, and the prosecution will decide whether to formally charge them.The SEC stated that Bitkub suffered a cyber attack in May 2021, resulting in the theft of 16 types of digital assets, with losses exceeding $50 million. Regulatory investigations revealed that Bitkub did not reflect the relevant losses in its daily net capital report Form DA 1 from May 10 to October 30, 2021. The SEC alleged that the relevant executives made false statements in the company's official documents, leading regulators to believe that customer assets were intact and that the company had not suffered financial losses. Bitkub subsequently completed the acquisition of alternative assets in late October 2021, but the SEC believes that the reports during this period constituted false statements.In a statement on July 23, Bitkub asserted that existing customer holdings are secure and accounts are complete. Bitkub stated that its co-founders purchased alternative assets in the same quantity and currency to cover the losses and claimed that the cyber theft incident was reported to law enforcement on May 10, 2021.

first_img Fidelity Q3 Signal Report: The net unrealized gains and losses of BTC, ETH, and SOL are all at historical lows, with multiple indicators approaching the capitulation zone

According to the Q3 2026 signal report released by Fidelity Digital Assets, the prices of BTC, ETH, and SOL are generally at historical lows, with multiple indicators close to the capitulation zone. Fidelity believes that the current valuation levels may correspond to attractive long-term entry conditions.As of the end of Q2, the weighted net unrealized profit and loss (NUPL) was -0.01, with BTC being the only asset with a positive unrealized profit, approximately 10% above its cost basis, with an unrealized profit of about $108 billion, while ETH and SOL were approximately 30% and 41% below their cost bases, with unrealized losses of about $87 billion and $29 billion, respectively. BTC's market share rose to 68% quarter-over-quarter.The report states that, based on historical backtesting, the current NUPL readings for the three correspond to one-year median returns of 53%, 70%, and 542%, respectively, but the reliability of the samples decreases sequentially. The NUPL reading for SOL has only occurred 21 times in history, concentrated at the end of 2025, which has limited statistical significance.On the fundamental side, the value of stablecoin transfers for both ETH and SOL has reached new highs, exceeding $20 trillion and $2.6 trillion, respectively, over the past 12 months, but network fee revenue continues to decline.Additionally, the report attributes the 22% decline in BTC hash rate from its peak to miners shifting their computing power towards AI and high-performance computing, as AI contract revenues are more stable due to the depressed coin prices.

Vitalik: The Diamond iO exploration program "stealth" new paradigm may drive privacy computing into a new stage

Ethereum co-founder Vitalik Buterin published a new article introducing a novel cryptographic obfuscation technology called Diamond iO. This technology aims to address the extremely low efficiency of traditional indistinguishable obfuscation schemes, allowing programs to run while hiding internal logic and critical data. Although traditional iO technology possesses strong privacy protection capabilities, its operational costs are prohibitively high, making it nearly impractical. Diamond iO, by adopting more aggressive new cryptographic assumptions, enhances computational efficiency from "universe-level time consumption" to "planet-level time consumption," bringing it closer to practical application.Diamond iO is built on technologies such as Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE). By encrypting programs, it allows users to execute the encrypted programs and obtain correct outputs without being able to view the internal code or hidden keys. This solution introduces a new input encoding mechanism and conditional decryption method, reducing computational complexity while ensuring the program logic remains hidden. Its core application scenarios include protecting programs that contain private keys, enabling secure software licensing, constructing trustless cryptographic services, and supporting blockchain and artificial intelligence systems with stronger privacy protection.However, Diamond iO is still in the early research stage, and its security relies on new cryptographic assumptions, including All-Product LWE and Evasive LWE, which require further research validation. At the same time, the technology still faces efficiency challenges such as high computational overhead and circuit depth limitations. Researchers believe that by optimizing underlying hash functions, improving homomorphic encryption schemes, and reducing security parameter requirements, Diamond iO is expected to become an important direction for advancing practical program obfuscation technology in the future.

hot_img WorkBuddy has been online for three months with a DAU exceeding 13 million, and Tencent's office agent is accelerating commercialization

According to a report by Z Finance, Tencent's AI-native desktop intelligent agent platform WorkBuddy entered public beta on March 9, achieving a monthly active user count of 20 million across all platforms within 3 months, with daily active users surpassing 13 million, including over 2 million daily active users on the PC side, and a DAU/MAU ratio stabilizing between 65%-75%. The product is led by Liu Yi, Vice President of Tencent Cloud, with a core team of about one hundred people, classified internally as one of the highest priority AI projects. The team claims they are currently only "temporarily ahead by half a position."WorkBuddy is derived from Tencent's previously launched AI programming assistant CodeBuddy, which has already covered about 12,000 engineers within Tencent. The product completed prototype development on January 17, and after the public beta in March, it has undergone a total of 43 iterations, gradually integrating capabilities related to QClaw developed by the Tencent PC Manager team based on an open-source framework. The product adopts a multi-model access strategy, with the underlying self-developed Harness engine for unified scheduling.In terms of commercialization, at the end of April, Tencent Cloud adjusted its pricing: the SaaS enterprise version was raised from 78 yuan/person/month to 198 yuan, and the private cloud enterprise version was raised from 158 yuan to 316 yuan. Market information indicates that it has acquired thousands of enterprise clients and over one hundred thousand paid seats, with an estimated annual revenue of about 300 million yuan. Third-party evaluations show that the product scored an average of 2.31/4 points on 70 questions (Word category 2.85 points, Design category 1.45 points), indicating that it is still some distance from producing stable results without manual modifications.
