Odaily reported that Bitcoin News posted on platform X, stating that Australian brewery Hawkesbury Brewing Co has integrated 16 Bitcoin miners into its brewing operations. By submerging the miners in non-conductive liquid and capturing the waste heat, the system harnesses this energy for the brewing process pipeline, supporting the production of 100,000 liters of beer per month.
Odaily Ethereum co-founder Vitalik Buterin has published a new article introducing Diamond iO, a novel cryptographic obfuscation technique. This technology aims to address the extreme inefficiency of traditional indistinguishability obfuscation (iO) schemes, allowing programs to execute while hiding their internal logic and critical data. Traditional iO technology offers privacy protection but at a high computational cost. Diamond iO, by adopting more aggressive new cryptographic assumptions, improves computational efficiency from "cosmological time" to "planetary time," bringing it closer to practical application. Diamond iO is built on technologies such as Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE). It encrypts programs, enabling users to execute the encrypted program and obtain correct outputs without viewing 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 guarantees.
Diamond iO is still in its early research stages. Its security depends on novel cryptographic assumptions, including All-Product LWE and Evasive LWE, which require further research and 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.
Odaily reported that Justin Ryan Schmidt, founder of 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 Schmidt, 46, pleaded guilty this year in federal court in Austin, Texas, to charges of underreporting his income between 2020 and 2022, declaring less than $5,000. However, prosecutors claimed that he actually earned over $7 million from his fund operations between 2019 and 2022. According to reports, Schmidt founded Translunar in 2017, primarily investing in blockchain startups, with funds mainly raised from investors in Austin, Texas, and Aspen, Colorado. The IRS Criminal Investigation Division arrested him on February 23, 2026, and he has been in custody since then. (Bloomberg)
Odaily Planet Daily reports that Solid Intel stated on the X platform that, according to mediators, after Iran and Oman approved a new proposal for the Strait of Hormuz, the United States and Iran are close to restoring their 60-day memorandum of understanding, with approval from Washington still pending.
According to Gate data, Brent crude oil once expanded its intraday decline to 4.00%, now reporting at $82.2 per barrel; WTI crude oil is currently down over 3%, reporting at $78.6 per barrel.
Odaily reported that Vida stated on X platform today that they sold nearly $7 million in put options, with the majority set to expire in one month. They noted that the current decline in the storage sector is, at least sentiment-wise, approaching its limit, and the implied volatility of storage stocks is at its highest historical percentile; demand related to AI continues, and the fundamentals remain unchanged. Regarding the sale of options at "prices that are difficult to trade" rather than prices closer to the current market, Vida said they prefer lower risk and more stable returns. Citing the MU 660 put option expiring in one month as an example, they stated that selling 15 contracts now could yield an immediate profit of $47,000. If MU falls below 660 in one month and triggers delivery, they will buy them for $1 million.
