CBS: U.S. Treasury Secretary and Trump Once Had Heated Debate on Tariff Policy

Ethereum Foundation researcher Toni Wahrst?tter announced in a post that core developers last week decided to delay the Hoodi testnet upgrade to Glamsterdam, following a ChainSecurity report uncovering compatibility and security issues between EIP-8037 and certain smart contracts. Identified problems include: residual gas may rise during transaction execution, causing underflow in some gas counting logic and triggering rollbacks, or activating code paths that should not execute, making transactions appear successful. Additionally, some contracts may incorrectly calculate gas consumption during calls, leading to underestimated usage. ChainSecurity previously noted it has found 13 real-world cases and is conducting responsible disclosure with affected projects. Wahrst?tter said further reviews of related contracts will be carried out this week to assess follow-up solutions, which may require collaboration among application developers, core developers, auditors, and node operators. In the worst scenario, protocol specifications may need adjustment. He urged application developers and auditors to verify their contracts’ compatibility with EIP-8037 and EIP-8038, and report issues promptly.

Beating AI Insight News Brief: Zhou Chang, core lead of ByteDance’s Seed AI, is again rumored to have resigned. Sources say he has submitted his resignation, plans to launch an embodied intelligence startup, and has been approached by multiple well-known funds and corporate venture capital arms. On October 26, both The Paper and Xin Huanghe reported that people close to ByteDance denied the resignation rumors. Zhou Chang previously served as technical lead of Alibaba’s Tongyi Qianwen, and joined ByteDance in 2024. Since then, he has taken over visual generation businesses including Seedance and Seedream. In June this year, ByteDance assigned its Seed Robotics team to his management. In other words, the rumored embodied intelligence startup direction is exactly the business he is already in charge of. This is not the first time Zhou Chang has faced resignation and startup rumors. In December 2025, he personally refuted the rumors on WeChat Moments, stating that the reports had affected his normal work.

Galaxy Research’s October snapshot shows that of the approximately 20.1 million mined Bitcoin, around 11.1 million (about 55%) are held in addresses unlinked to exchanges, funds, governments, or other known entities. Galaxy Research Director Alex Thorn stated that this demonstrates that despite growing institutionalization, a large volume of Bitcoin is still likely self-custodied by individuals. Xapo Bank notes this reflects retail investors having entered the space over a decade ago. However, this unassigned Bitcoin is not all held by long-term self-custody individuals; it may also include coins inaccessible due to lost private keys or deceased holders, institutional or OTC trader positions unrecognized by Galaxy, and custodial assets spread across multiple addresses. The remaining 45% is already attributed, including exchanges, ETF issuers such as BlackRock, and the U.S. government. The single largest holder is "Satoshi Nakamoto (Patoshi pattern)", holding 1,123,658 BTC.
