According to a report released by CryptoQuant's research director Julio, the current open interest in cryptocurrency perpetual contracts is approximately $65 billion, down about 20% from the peak of around $80 billion in September 2025 and early 2026, reflecting some deleveraging rather than new capital inflows. The market is highly concentrated, with Binance dominating with about 39% market share, the top three platforms accounting for about 63%, and the top five making up about 81%, indicating that capital is highly concentrated in leading exchanges.The report states that, at the same time, TradFi perpetual contracts for metals, crude oil, and stocks have become a growth highlight. This 24-hour, round-the-clock product has doubled in scale to over $2 billion since the end of May, allowing crypto trading to compete directly with traditional trading venues, although its size currently accounts for only about 3% of the crypto perpetual market. TradFi perpetual contracts are also dominated by leading platforms, with Binance, Gate, and Bybit at the forefront, showing that platforms with mature infrastructure and liquidity are extending their advantages into traditional asset tracks.

Justin Ryan Schmidt, the founder of the cryptocurrency investment fund Translunar Crypto LP, has been sentenced to 37 months in prison by a U.S. court for tax evasion. The U.S. Department of Justice stated that the 46-year-old Schmidt pleaded guilty this year in federal court in Austin, Texas, where he was accused of underreporting income, declaring less than $5,000 in income from 2020 to 2022, while prosecutors claimed he actually earned over $7 million through fund operations from 2019 to 2022.It is reported that Schmidt founded Translunar in 2017, primarily investing in blockchain startups, with funding mainly coming from investors in the Austin area of Texas and Aspen, Colorado. He was arrested by the IRS Criminal Investigation Division on February 23, 2026, and has been in custody since then.

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.
