In April 2026, the DeFi sector experienced multiple attacks exploiting non-code vulnerabilities, resulting in losses exceeding $625 million. Attackers utilized administrator private keys, cross-chain bridge validators, and social engineering tactics, revealing that DeFi security issues lie not in the code but in operations and mental models. The industry needs to reassess the definition of decentralization, emphasizing operational security and transparency. In the future, protocols must disclose operational leverage to ensure user awareness and establish insurable operational risk models.
Vitalik emphasizes that Ethereum should maintain its idealism and not become another Google. The Ethereum Foundation is no longer the center but rather a node with clear objectives. Vitalik suggests that Ethereum must excel in the CROPS dimensions, striving for bug-free, high availability, and minimal intermediation. Although the Foundation is reducing its responsibilities, the market still needs to create organizations aligned with Ethereum's economic interests to fill the alignment gap.
Vitalik believes that the Ethereum Foundation (EF) should become a smaller, more distinct organization, focusing on long-term goals rather than short-term expansion. EF will concentrate on Ethereum's censorship resistance, openness, and security, reducing reliance on intermediaries. Vitalik emphasizes that EF is not the center of Ethereum but a node alongside other nodes, and it will continue to lead technological innovation in the future.
Kevin Warsh becomes the Federal Reserve Chairman, proposing a 'balance sheet reduction + interest rate cut' policy aimed at reshaping the Fed's monetary policy. His reforms could impact global capital markets and the US dollar credit system. Although Warsh lacks a traditional academic background, he has extensive Wall Street experience and understands capital market operations. His policy proposals face challenges from fiscal expansion and resistance to monetary tightening, potentially leading to volatility in the US Treasury market and loosening of US dollar credit. Warsh emphasizes the Fed's independence, but the flexibility of his policies has drawn attention.

Yanhua Antonio Gullí's book explores the design patterns of AI Agents, emphasizing the evolution from raw LLM to multi-agent collaboration. The book introduces Context Engineering and Reflection patterns to help agents improve efficiency and accuracy. The author points out that a single agent, combined with tools, reflection, and memory management, can handle most scenarios. The book also discusses the communication topology of multiple agents and future development hypotheses.
Google DeepMind's Chief Scientist Shanahan explored the mental attributes of Large Language Models (LLM) at the International Conference on AI and Philosophy at the University of London. He analyzed the applicability of LLMs in areas such as understanding, belief, agency, self, and consciousness, emphasizing the impact of multimodality and embodiment on conceptual evolution. Shanahan believes that the identity of LLMs is peculiar, with role-playing and superposition making their self transient and discontinuous. Regarding consciousness, he advocates focusing on the engineered interaction with LLMs rather than whether they possess consciousness.
