Beating AI Express, Anthropic has revealed that approximately 90% of Claude Code’s code is written by Claude. From June to September this year, the number of pull requests (PRs) merged by the Claude Code team more than doubled, while the proportion of PRs needing reversion dropped by over 40%. To keep pace with AI’s coding speed, Anthropic has revamped its code review process: before each commit, Claude runs tests first and has independent sub-agents inspect changes; after submission, multiple agents hunt for bugs in parallel, followed by cross-validation from another set of agents. Security reviews and automated tests also block problematic code from merging. Human reviews are tiered by risk: low-risk changes like documentation updates from trusted developers can be merged directly after passing automated checks; regular product modifications require one human approval, while high-risk code changes need two. AI approval cannot replace human oversight, and developers remain responsible for the final code. However, AI reviews can get stuck in loops. Anthropic disclosed that one Claude Code modification went through over 50 rounds of review and fixes overnight. The team found about 59% of the issues stemmed from code that existed during the first review, not new problems introduced by later changes. The team subsequently adjusted rules: if a change goes through more than three rounds of review, the author must reevaluate their approach, and repeated feedback is limited to prevent agents from getting stuck in back-and-forth loops.

Cysic Foundation announced that a security incident occurred on its cross-chain bridge on October 17, during which an attacker minted 10 million CYS tokens on BNB Smart Chain without authorization. After detecting anomalies, the project team has suspended the cross-chain bridge, placed relevant addresses on an on-chain blacklist, and hired a professional security firm to investigate the attack path and fund flows. Preliminary investigations indicate the attacker gained unauthorized access to the database supporting the cross-chain bridge service and exploited a vulnerability in the processing logic to submit fake minting requests. The incident only impacted the cross-chain bridge's message processing and minting functions; Cysic's mainnet and other operational systems remain unaffected, and no user assets have been stolen. As of press time, the relevant addresses still hold approximately 2.8 million CYS, which have been restricted from transfer. The project team noted that the 10 million CYS minted does not equate to final dollar losses; actual losses and follow-up fund tracking results are still under verification, and the cross-chain bridge will be reopened only after security reviews are completed. Per HTX market data, Cysic (CYS) is trading at $0.118, down 6.2% in 24 hours, with a market cap of $19 million.

Crypto analyst Darkfost stated in a post that since the end of August, mid-cap and small-cap tokens have posted the strongest market capitalization growth. Data shows the gap between the annual average and monthly average market cap of these assets has continued to widen, with the current ratio reaching 41%. By contrast, Bitcoin’s growth trend is positive but limited, standing at only 7%, while large-cap assets have an even lower ratio of 3.5%. The analyst pointed out this is a quite rare phenomenon. Normally, Bitcoin drives market trends, as was clearly seen in the period after the end of the 2023 bear market. However, mid-cap and small-cap tokens are more sensitive to market funds and sentiment, and their trends may reverse rapidly in either direction in the short term. Investors need to be alert to the high volatility risks brought by this structural feature.

Microsoft has canceled its partnership with UK data center firm Nscale for the Loughton data center in Essex. Nscale was set to serve as the facility’s anchor tenant, with plans to lease around 23,000 Nvidia AI chips. The project was part of Microsoft’s 22-billion-pound UK investment pledge announced last year. Nscale is pursuing a U.S. initial public offering (IPO) valued at up to roughly $35 billion, and Microsoft’s withdrawal is viewed as a major setback for the company. The project also faces a delay in grid power supply, which is now pushed back to the 2030s. Nscale previously stated that over 40% of its $103 billion in contracted revenue comes from Microsoft, though this UK deal is believed to represent a smaller share, with Anthropic being another key client.
