Odaily news, Ethereum co-founder Vitalik Buterin published a new article introducing Diamond iO, a novel cryptographic obfuscation technique. This technology aims to solve the extremely low efficiency problem of traditional indistinguishability obfuscation schemes, allowing programs to run while hiding their internal logic and critical data. Traditional iO technology offers privacy protection capabilities but has high operational costs. Diamond iO adopts a more aggressive new cryptographic assumption, improving computational efficiency from "cosmic-level time consumption" to "planetary-level time consumption," moving closer to practical application. Diamond iO is built upon technologies such as Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE). By encrypting programs, it allows users to execute the encrypted program and obtain correct outputs without being able to view its internal code or hidden keys. This scheme introduces a new input encoding mechanism and conditional decryption method, reducing computational complexity while ensuring program logic is hidden. Its core application scenarios include protecting programs containing private keys, enabling secure software licensing, building trustless cryptographic services, and supporting blockchain and AI systems with stronger privacy protection.
Diamond iO is still in the early research stage, and its security relies on novel cryptographic assumptions including All-Product LWE and Evasive LWE, requiring further research for 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 has the potential to become an important direction for advancing practical program obfuscation technology in the future.
Người sáng lập quỹ tiền điện tử Translunar bị kết án 37 tháng tù vì tội trốn thuế, liên quan đến việc che giấu 7 triệu USD thu nhập
Odaily星球日报讯 Người sáng lập quỹ đầu tư tiền điện tử Translunar Crypto LP, Justin Ryan Schmidt, đã bị tòa án Hoa Kỳ kết án 37 tháng tù giam vì tội trốn thuế. Bộ Tư pháp Hoa Kỳ cho biết, Schmidt, 46 tuổi, đã nhận tội vào đầu năm nay tại Tòa án Liên bang Austin, Texas. Anh ta bị cáo buộc khai báo thu nhập thấp hơn thực tế trong giai đoạn 2020-2022, chỉ khai báo thu nhập dưới 5.000 USD, nhưng các công tố viên cho biết anh ta thực tế đã thu được hơn 7 triệu USD từ hoạt động của quỹ trong giai đoạn 2019-2022. Được biết, Schmidt thành lập Translunar vào năm 2017, chủ yếu đầu tư vào các công ty khởi nghiệp blockchain, với nguồn vốn chủ yếu đến từ các nhà đầu tư tại Austin, Texas và Aspen, Colorado. Cơ quan Điều tra Hình sự của Sở Thuế vụ Hoa Kỳ đã bắt giữ anh ta vào ngày 23 tháng 2 năm 2026, và anh ta bị giam giữ kể từ đó. (Bloomberg)
Odaily đưa tin, Solid Intel đăng trên nền tảng X rằng, theo các bên hòa giải, sau khi Iran và Oman phê duyệt một đề xuất mới về eo biển Hormuz, Mỹ và Iran đã tiến gần đến việc khôi phục bản ghi nhớ 60 ngày của họ, trong khi sự chấp thuận từ Washington vẫn đang chờ xử lý.
Theo dữ liệu từ Gate, mức giảm trong ngày của dầu thô Brent đã mở rộng lên tới 4,00%, hiện ở mức 82,2 USD/thùng; dầu thô WTI hiện giảm hơn 3%, ở mức 78,6 USD/thùng.
Odaily Planet Daily News: Vida posted on platform X, stating that today they sold nearly $7 million worth of put options, with the majority set to expire in one month. They mentioned that the current decline in the storage sector has at least reached a psychological limit in terms of market sentiment, with the implied volatility of storage stocks at an all-time high percentile; AI-related demand continues and the fundamentals have not changed. Regarding the decision to sell at prices "difficult to execute" rather than closer to the current market price, Vida expressed a preference for lower risk and more stable returns. Using the example of MU put options expiring in one month at a strike price of 660, they stated that selling 15 contracts now would immediately yield a profit of $47,000. If MU falls below 660 and triggers exercise in one month, they would buy them back for $1 million.
Odaily Odaily Planet Daily reported that Daru Electronics (300976.SZ) announced that its wholly-owned subsidiary, Ruichuang Future, holds a stake in Dongguan Guangfa Xinde, whose invested subsidiary Guangzhou Xinde owns shares in ChangXin Memory Technologies (stock code: 688825), which will be listed on the STAR Market on July 27, 2026. Based on the calculated shareholding proportion, the company indirectly holds approximately 1.6886 million shares of ChangXin Memory Technologies, with a lock-up period of 36 months for these shares. The company classifies its investment in the Dongguan Guangfa Xinde fund as a financial asset measured at fair value through profit or loss. Price fluctuations of ChangXin Memory Technologies' stock may impact the company's financial condition, with details to be confirmed in the periodic reports. (Cailianshe)
According to a Reuters poll, after gold prices sharply retreated from their January record highs, analysts have cut their gold price forecasts for the first time since late 2023. However, most still expect central bank buying and concerns over fiscal sustainability to provide support. The survey of 29 analysts and traders over the past three weeks showed a median gold price forecast of $4,509 per ounce for 2026. This figure is down from $4,916 three months ago and marks the first downward revision in 11 quarters. The average forecast for 2027 stands at $4,610, compared to $5,100 in the previous survey. Gold prices hit an all-time high of $5,595 per ounce in January but experienced a sharp pullback in the second quarter, as the war in Iran exacerbated energy inflation and raised expectations for interest rate hikes, leading to the worst quarterly performance since 2013. Since the outbreak of the war, spot gold has fallen by approximately 22%.
The Odaily Planet Daily reported that according to Gate data, US and Brent crude oil prices have both dipped in the short term, with WTI crude oil falling below $79 per barrel, a daily drop of 2.67%; Brent crude is currently down about 3.6%, trading at $82.2 per barrel.
