ChainCatcher message, Binance founder Zhao Changpeng posted a security alert on X, "If you are using a Macbook with an Intel chip, please update as soon as possible! Stay safe!"It is reported that Apple has confirmed that the macOS system has been subjected to zero-day attacks and has urgently released major security updates for macOS and iOS to fix two vulnerabilities that have already been widely exploited.Apple confirmed in the announcement that these vulnerabilities are being widely exploited on Intel-based macOS systems and urged users across the ecosystem to urgently apply iOS 18.1.1, macOS Sequoia 15.1.1, and the older iOS 17.7.2.

ChainCatcher news, Bankless founder David Hoffman posted on social media, "Ethereum development has prioritized L2 execution for over 2 years. This has come at the expense of L1 execution. L1 execution is lagging behind Moore's Law, while L2 has gained undue growth and valuation subsidies from L1. Therefore, we should re-establish the priority of L1 execution work. I agree with @MaxResnick1 that the hardware requirements for L1 should be 'the latest 2 generations of Macbook Pro', which aligns perfectly with the social contract of individual stakers. This would increase the accessibility of Ethereum L1 to over 10 times the users, and at a low cost.The argument against this is: the Ethereum ecosystem needs to reorganize around fewer synchronous composability—growing L1 execution will reduce the urgency to solve this problem. An rollup-centric Ethereum is the right roadmap—let's face the challenges head-on."
