The knowledge management application Notion has released an announcement acknowledging that some users' AI chat records have been leaked. The company stated that the affected workspaces account for less than 1% of all workspaces and is currently notifying the affected users. If users have provided their account, password, or credentials to the AI, Notion recommends treating them as compromised, immediately checking the login records of the relevant accounts, and changing passwords or credentials.The source of this incident is a hacker attack on the service provider Fireworks. Notion uses Fireworks AI to process data for a feature called Insights, which helps workspace administrators understand how team members are using AI. To generate this analytical data, Notion sends the saved AI conversation content to Fireworks for processing. Fireworks has also served as the inference service provider for some open-weight models in Notion's products.Notion stated that the potentially leaked data mainly consists of user chat records, including the chat content input by users and the replies given by the AI. The announcement explained that some users may have sent their account, password, or various credentials to the model while using AI. Notion advises the relevant users to immediately change these passwords or credentials and check for any unusual activity in their account login records.

Hugging Face CEO Clément Delangue expressed that the departure of Nvidia CEO Jensen Huang is "a very sad day," and hopes that such things never happen. He also stated that Hugging Face will work harder than ever for open-source AI, which is crucial, and that there can be no slowing down now. Nvidia has appointed Chief Financial Officer Colette Kress as interim CEO.In September, Nvidia announced plans to acquire the open-source AI model platform Hugging Face for $12.9 billion, with the transaction expected to be completed in the first half of 2027. This deal ranks as the second largest in Nvidia's history, only behind its acquisition of chip company Groq's assets for $20 billion in December 2025. The U.S. Department of Justice has launched an inquiry in October regarding the impact of this acquisition on competition in the AI market, and Nvidia previously committed that the Hugging Face platform would remain open and supportive.

According to Serenity, Jensen Huang is almost irreplaceable for Nvidia. Serenity stated that this is similar to how Tesla's valuation and market confidence could collapse if it lost Elon Musk.Serenity mentioned that Jensen Huang bet on CUDA before the explosion of artificial intelligence and began building the Neocloud ecosystem; he locked in key supply chain capacity years in advance and launched rack-level systems that integrated components like CPUs and networking devices. Jensen Huang also transformed the competitive threat posed by ASICs into new development opportunities by investing in companies like Marvell and MediaTek, competing with Broadcom, while incorporating these partners into Nvidia's NVLink ecosystem.Serenity also stated that Jensen Huang almost single-handedly built the financial and industrial ecosystem surrounding the current AI investment boom, growing Nvidia from a startup into a company with a market value exceeding $5 trillion, with an expected future growth rate of 70% by fiscal year 2028. Serenity indicated that even if Nvidia's actual revenue or product roadmap does not undergo substantial changes in the next two years, simply replacing Jensen Huang could have catastrophic effects on Nvidia's long-term development.

The Solana block space market Gravity Block Exchange (GBX) has announced its launch on the Solana mainnet. GBX positions itself as an open and neutral block space market, where block builders compete for the ordering of each block through auctions, rather than having a single scheduler complete the ordering. Its goal is to create a unified ordering market that increases the value of validator block space through competition among builders, while providing users with a clear set of rules.The mainnet operation status announced by GBX includes: approximately 5% of the total staked validators have been connected, with rewards 20% to 30% higher than the cluster average. Currently, there are two independent block builders participating in each round of auctions, namely Bifrost from Astralane and Titan Builder from Gattaca. Public documents show that validators can connect through the Gravity Connector sidecar without the need for a custom validator fork, currently supporting Agave and Jito-Solana, while support for Firedancer is still in development; when external ordering paths are unavailable, validators can fall back to the native scheduler.

More than a week after the "blue wave" in the U.S. midterm elections allowed the Democratic Party to gain control of both the House and Senate, there are still 14 election results yet to be announced. According to Stand With Crypto, the results that have been announced have increased the number of crypto supporters in both chambers, and the remaining elections may bring in more supporters. In the undecided House races, three candidates have received support from the crypto political action committee (PAC), and all candidates in these districts are classified as "strongly support crypto" or "undecided."Specifically, Alaska Congressman Nick Begich is currently leading, with Fairshake's Republican affiliate Defend American Jobs investing $508,000 in him during the primary in early August; the same PAC invested $150,600 in North Carolina's 7th District Congressman David Rouzer, who is also leading. Louisiana State Senator Blake Miguez will enter the runoff on December 12 against the state's 6th District Democrat Chauna Banks, with Fellowship PAC investing $250,000 in him. On November 11, the Associated Press determined that South Carolina's 2nd District incumbent Congressman Joe Wilson won, and Stand With Crypto rated him as "strongly support crypto." His victory brings the total number of crypto supporters in the House to 246 and opponents to 107, while the Senate has 50 supporters and 33 opponents.Lindsay Fraser, Chief Policy Officer of the Blockchain Association, stated that the undecided new lawmakers "represent an opportunity." She noted that nearly a quarter of the new Congress members are newcomers, many of whom have not given much thought to blockchain technology, which is akin to "a blank slate." The association plans to organize outreach activities in January next year to engage newly elected lawmakers, aiming to get more lawmakers into Stand With Crypto's A and B ratings. She also mentioned that age influences lawmakers' crypto voting tendencies more than party affiliation, with lawmakers under 55 being significantly more likely to support the industry, and the new Congress overall being younger; she hopes the industry can face two candidates with in-depth thoughts on the industry in the 2028 election, avoiding the industry's fate being dependent on a single election outcome.

Elon Musk stated that SpaceX is expected to achieve actual usable computing power next year that is approximately equivalent to half of the global scale. He emphasized that "actual usable" is an important metric, and it is expected to take two months of continuous work to stabilize the large computing clusters, while other companies may need six months.

According to the Wall Street Journal, Nick Timiraos, known as the "mouthpiece of the Federal Reserve," wrote that after the third consecutive strong inflation report was released, a rate hike by the Federal Reserve in December is almost certain. Market focus is shifting to the magnitude of the rate hike and the subsequent pace, including a 25 basis point hike at each meeting, a one-time hike of 50 basis points, or signaling multiple consecutive hikes of 25 basis points.Nick Timiraos pointed out that the Federal Reserve will hold a policy meeting from December 8 to 9, and the bigger question is whether this rate hike is a moderate adjustment envisioned by several officials, with two to three more hikes, or the beginning of a sustained effort to suppress the economy and lower inflation.Previously, Federal Reserve Governor Waller, who supported maintaining interest rates last week, stated that if the core price increase in October reaches about 0.3% month-over-month, the Federal Reserve should consider a 50 basis point hike in December, and the latest published data happens to align with this scenario. Dallas Federal Reserve President Logan also hinted after the data release that, given the current inflation pressures, it may be necessary to accelerate the pace of rate hikes. The relevant tactical choices are usually decided by the Federal Reserve Chair.

According to Bitcoin.com News, former White House cryptocurrency advisor Patrick Witt stated that President Trump still intends to purchase Bitcoin for the United States' strategic Bitcoin reserve, but public market purchases face serious legal issues. Witt mentioned in the What Bitcoin Did podcast that the president is interested in this, and there have been many discussions related to it. An executive order from March 2025 established the reserve, gathering Bitcoin seized by the government, and instructed the Treasury and Commerce Departments to seek "budget-neutral" acquisition strategies, but no such strategies have been made public, nor has any public market purchase been announced.Witt indicated that due to Congress controlling federal spending, the "legitimacy" of direct public market purchases is in doubt. He also noted that concerns over purchases prompted Congress to include provisions in the National Defense Authorization Act prohibiting such actions, and he is working to push for permission and authorization for it. Witt pointed out that making the reserve permanent is more difficult, as passing a standalone bill in a divided Congress would be extremely challenging, and without legislation, the reserve would rely on executive orders, which future presidents could revoke.
