More →Nvidia executive: AI safety should not slow technological progress
According to news from Bijie, Nvidia Senior Software Director Ali Golshan said in an exclusive interview that AI security does not require slowing down the pace of technological advancement. He pointed out that security has always been a factor that accelerates development, rather than slowing it down. He mentioned that when SSL and encryption became the default, the internet developed faster. He also emphasized that agents fail or deviate from their tasks because they lack sufficient trust to handle real context. Using the metaphor of hiring a contractor to fix a leak, he explained that clearly indicating where the problem is can lead to a more effective solution. The core idea of Nvidia's Openshell platform is that companies that first build trust and governance into agents will be able to handle more sensitive data and greater autonomy, thereby achieving faster progress.

Arbitrum pauses new Stylus contract activation to address AI attack risk.
According to news from Bijie, the Arbitrum Security Council temporarily blocked new Stylus contract activation on the Arbitrum One and Nova networks at 07:30 (UTC+8) on October 3. This restriction targets programs requiring entirely new activation and application updates. Already activated Stylus applications continue to run, and ordinary Solidity contract deployment and execution are unaffected. Arbitrum officially stated that this preventive measure stems from the threat of WebAssembly program attacks targeting non-standard Stylus compiler toolchains. At present, no risk of stolen funds has been found; the main concerns are on-chain activity and denial-of-service (DoS) attacks.
