CONCLUSION-

8 notable security incidents have occurred in the past week. Seven of them were attacks on smart contracts and social media and one was suspected to be a rug-pull.

A Reminder for Project Teams: Always test thoroughly. Do smart contract audits before deploying smart contracts on-chain.

A Reminder for Crypto Users: Be cautious about suspicious links, emails, websites, and projects launched by teams without established reputations. Particularly we suggest crypto investors should avoid investing in projects whose admins(owners) obtained their gases from Tornado Cash. If projects of this kind turn out to be rug-pulls, it is hard to take back/recover assets from them.

It is important for everyone in the crypto community to gain understanding and practice sufficient levels of cybersecurity.

  • Samsung Invests 60 Trillion Won in Physical AI Industry Cluster

    On July 3, Samsung announced an investment of approximately 60 trillion won in the Yeongnam region of South Korea to establish production centers for humanoid robots, solid-state batteries, AI server packaging substrates, and high-value-added ships. This initiative aims to integrate artificial intelligence transformation (AX) and robotics with existing manufacturing, positioning the Yeongnam region as a global leader in physical AI innovation clusters. Samsung Electronics President and DX (Device Solutions) Head, Roh Tae-moon, attended a national briefing on the vision for advanced industry development in Yeongnam held at Gyeongsang National University in Jinju, South Gyeongsang Province. He stated, 'We will create 200,000 high-quality jobs in the Yeongnam region by concentrating investments in humanoid robots, AI data centers, and advanced manufacturing.' Following Roh's speech, Samsung released a press statement detailing the group-level investment plan centered around Gimhae, Ulsan, Busan, and Geoje.

  • Kioxia and SanDisk Begin Production of 10th Generation 3D Flash Memory at Fab2

  • Deutsche Bank: Meta's Cloud Business Could Open a $100 Billion AI Monetization Channel

    On July 3, in response to news that Meta plans to sell AI computing power and model access to external clients, Deutsche Bank believes this does not indicate a weakening of Meta's frontier models or 'superintelligence' strategy. Instead, it is more likely that Meta is monetizing older, non-core, or temporarily idle computing power while retaining the latest generation chips for internal training. This move is expected to shift market concerns about Meta's 'high capital expenditures and limited revenue returns' towards a reassessment of its new high-profit revenue options. According to Deutsche Bank's estimates, by the end of 2027, Meta's AI-related computing power could reach between 8 to 11.5 GW, with approximately 1.2 to 2.7 GW available for external sale. Assuming 75% of this capacity is sold, with annual revenue of $10 billion to $15 billion per GW, Meta could generate an additional revenue of $9 billion to $30 billion by 2027, which is 3% to 10% higher than market expectations, with a baseline scenario of about $17.5 billion.

  • JPMorgan: Demand for AI Infrastructure Supported by Rising Usage of Large Models and GPU Rental Prices

Although the price of model tokens has continued to decline year-on-year, the growth in usage has clearly offset the impact of price reductions, leading to an overall improvement in the unit economics for model providers.
