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 TrendForce: AI demand drives Japanese and Korean MLCC suppliers to achieve the highest shipments in June in five years, with consumer-grade order overflow boosting prices from Taiwanese and Chinese manufacturers

According to the latest survey by TrendForce, in June, the top three MLCC suppliers in Japan and South Korea (Murata, Samsung Electro-Mechanics, Taiyo Yuden) achieved a monthly shipment volume that reached a nearly five-year high, with 140 billion, 98 billion, and 40 billion units respectively, and the growth momentum continued into July. AI applications are the main driving force, with CSP manufacturers maintaining strong procurement demand for self-developed ASIC platforms such as Google TPU and AWS Trainium, driving continuous growth in demand for high-capacity, low-voltage, small-sized MLCCs.At the same time, Japanese and South Korean suppliers are accelerating the shift of production capacity from consumer-grade X5R to high-end X6S/X7R specifications, resulting in a severe squeeze on the production capacity of mid-to-high capacity (1µF-22µF) consumer-grade MLCCs, with mainstream inventory days generally falling below 30 days. The overflow effect of production capacity has led channels, agents, and second- and third-tier customers to urgently pull goods, significantly increasing order visibility for Taiwanese and mainland suppliers, leading to rising prices, with agents raising prices by an average of 20-25%, and spot market prices have soared to 2-3 times the original price. TrendForce pointed out that the consumer-grade MLCC market currently shows a structural mismatch of "weak end demand, strong channel pricing."

Bitwise CIO: The crypto market shows signs of bottoming out, with the next bull market driven by the integration of on-chain and traditional finance

Bitwise Chief Investment Officer Matt Hougan published an analysis, stating that the crypto market is showing signs of a bottom ------ since July 1, Bitcoin has risen by 9% while the Nasdaq has fallen by 6%, ETF fund flows have turned positive, and market sentiment has improved. Hougan believes that the next bull market will be driven by the integration of on-chain finance and traditional finance, with the core sectors being stablecoins, tokenization, 24/7 trading, instant settlement, and institutional DeFi.He suggests focusing on two types of opportunities: one type is crypto-native applications represented by Hyperliquid (HYPE) ------ which have real revenue and a strong token economic model (99% of revenue is used for buybacks and burns of HYPE), which has risen 146% this year; the other type is traditional financial institutions represented by Robinhood (HOOD) ------ whose Layer2 blockchain Robinhood Chain attracted over $300 million in deposits within two weeks of launch, processing an average of 3.6 million transactions daily, supporting 24/7 trading of tokenized stocks for users in 120 countries. Hougan is optimistic about mainstream assets such as Bitcoin, Ethereum, and Solana, as well as crypto stocks, while also paying attention to institutions like Coinbase, Figure, BlackRock, Visa, Stripe, and JPMorgan that are scaling up in the crypto space.
