Vitalik: Diamond iO Enables Programs to Run While Hiding Internal Logic and Critical Data
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.
Claude Opus 5 Tops Artificial Analysis Intelligence Index v4.1
Anthropic's Claude Opus 5 (max and xhigh versions) achieved the highest intelligence score on the Artificial Analysis Intelligence Index v4.1. The index integrates 9 evaluation benchmarks including GDPval-AA v2, GPQA Diamond, and Humanity's Last Exam. Previously, Opus 5 has demonstrated leading performance in multiple benchmark tests, including scoring twice that of the previous generation on Frontier-Bench, topping the AA-Briefcase agent benchmark, and outperforming Fable 5 in cost-performance ratio.
Peter Brandt: Nasdaq Futures Show Diamond Top Formation, Bitcoin May Bottom at $40,000
Peter Brandt, a seasoned trader and renowned chart analyst, has released his latest technical analysis. He points out that the daily chart of Nasdaq 100 mini futures is forming a diamond pattern, indicating a potential market top. Regarding Bitcoin, Brandt offers a forecast based on historical cycles: BTC may first rebound by $10,000, then retreat to the $40,000 range, forming the bottom of the current cycle around early October 2026. With the current price fluctuating near $60,000, he warns of the downside risk associated with false breakouts. Maintaining a long-term optimistic view, Brandt suggests that if Bitcoin continues its four-year halving cycle pattern, the price could reach between $300,000 and $500,000 by 2029.

British sprint star CJ Ujah charged in crypto fraud case
according to a UK police announcement, former World Athletics Championships 4x100m relay gold medalist and British sprinter CJ Ujah, along with nine other individuals, has been charged with "conspiracy to defraud" in connection with a cryptocurrency fraud case.Police stated that the criminal gang posed as police and cryptocurrency company personnel to conduct phone scams against multiple victims, tricking them into disclosing critical wallet security information, including seed phrases. The perpetrators then transferred the victims' crypto assets, with one victim losing over £300,000. The case was cracked following a joint investigation by the Eastern Region Special Operations Unit (ERSOU) across Kent, Essex, and London. The ten suspects have appeared in court, with Ujah released on bail until a further hearing on May 28.Ujah, now 32, won a 4x100m relay gold medal for Team GB at the 2017 World Championships and also claimed the Diamond League title that same year. In 2022, he was suspended for 22 months due to a doping violation, which was later attributed to contamination from a supplement causing an adverse analytical finding. In addition to Ujah, another British sprinter, Brandon Mingeli, is also on the list of those arrested and is currently in custody pending trial. (The Guardian)
