Claude conversations could be found on Google; users discovered it by accident and it drew attention
Would you chat with an AI chatbot about some private matters? A Reddit user recently discovered that by entering a search directive like "site:claude.ai/share" into Google, they could pull up hundreds of complete conversation records between other users and Claude.
The user said that using the search engine’s on-site search syntax exposed more than 200 conversations, spanning at least 25 pages of search results. Some of the conversations even happened weeks earlier. The post garnered around 4,000 likes on Reddit, and the incident quickly went viral online, though the issue appeared to have been fixed as of the time of writing.

Opposition nominates candidates, with Bitcoin policy becoming a key battleground
Salvadoran politics for the February 2027 presidential election is gradually heating up, as the two main opposition parties have already put forward challengers, putting President Nayib Bukele’s third-term plans and the country’s Bitcoin ($BTC) policy in step under scrutiny. ARENA, the National Republican Alliance, nominated former National Assembly member Maytee Iraheta, while the Farabundo Martí National Liberation Front (FMLN) put forward physician and labor union leader Rafael Aguirre. Both have not supported the Bitcoin approach led by Bukele and have criticized it as a failure in fiscal policy.

Cardano (ADA) founder Charles Hoskinson entered the crypto world years ago through Bitcoin. Now, he has boldly predicted that the cybersecurity threats brought by “quantum computing” in the future will become the ultimate test of the ability to upgrade Bitcoin systems. If consensus can’t be effectively forged and system upgrades can’t be pushed through smoothly, Bitcoin may risk losing its throne as the “king of cryptocurrencies.”
In contrast, Charles Hoskinson believes Cardano has a well-developed on-chain governance mechanism that can respond more flexibly and quickly to technical challenges that could mean life or death for the network. He points out that:
Bitcoin’s biggest problem is that its technical development seems frozen in time—pushing any system changes is as difficult as reaching the sky.

Cloud project Storj files for bankruptcy reorganization as the crypto sector sees 5 companies collapse in a week
Decentralized cloud storage provider Storj Labs announces bankruptcy. It has recently filed for bankruptcy reorganization under the U.S. (Bankruptcy Act) Chapter 11 (case number 5:26-bk-00512).
This case is the 5th crypto company within the past week to announce a shutdown, reorganization, or termination of operations, highlighting that crypto players with fragile finances face a severe survival crisis as market funding rapidly shifts toward the artificial intelligence (AI) sector.
Storj plans a rare “token-for-equity” deal
According to an official Storj announcement, this bankruptcy filing is intended to address early debts left over from past mergers and acquisitions. During the reorganization period, the company will maintain normal operations, and its core storage services and customer support will not be affected.

In July 2026, Nomura’s Global Markets Research division released a report (Advanced Semiconductor Testing: Chip Upgrades, Test Follow-Through), highlighting that semiconductor testing has evolved from a low-value-added process at the end of manufacturing into one of the most strategically valuable segments in the AI hardware supply chain.
Reports that Wanxie (6223), Yingwei (6515), and Hongjin (7769) have been issued buy ratings, restores the buy rating for ZhiMao (2360), and maintains the buy ratings for ASE Technology (3711) and Jingyuan Electric (2449). Target prices for six listed Taiwan testing concept stocks are all expected to deliver returns ranging from 11% to 73%.

Circle acquires IBM blockchain patent portfolio
Circle, a stablecoin issuer, announced its acquisition of IBM's blockchain patent portfolio, obtaining more than 680 patent families and nearly 1,000 globally granted patents.
Circle said the deal makes it the largest holder of blockchain patents in the United States, allowing the company to build a deeper intellectual property moat in the competition for on-chain financial infrastructure.
These patents cover foundational blockchain technologies, banking and financial services, insurance, enterprise infrastructure, supply chain verification, and secure cloud computing, among other industries. The transaction amount has not been disclosed, and it is still unclear whether IBM will retain certain licensing rights or whether Circle will license, assert, or enforce these patents externally in the future. IBM has long been one of the most active companies in building a blockchain patent portfolio in the United States. This sale effectively transfers its long-accumulated key assets to Circle.

Asian stocks saw a sharp correction at the open today (7/28) after the U.S. stock market’s Philadelphia Semiconductor Index fell and concerns about AI-related capital expenditures resurfaced. Taiwan stocks plunged more than 1,700 points in the morning session, breaking below the 42,000-point level outright. Markets in Japan and South Korea also dropped in tandem; the South Korean market (KOSPI) even triggered the circuit breaker mechanism again during the day, halting trading for 20 minutes.
Taiwan stocks plunge by more than 1,000 points; TSMC slips below its quarterly moving average
Taiwan stocks opened to a barrage of selloffs today, with the intraday low reaching 41,830.09 points. Leading heavyweight TSMC fell 80 yuan in the early session (down 3.4%) to 2,270 yuan, breaking below its quarterly moving average again (2,347 yuan). In the memory sector, Winbond and Nanya Technologies also saw even deeper declines at one point, hitting the daily limit down.

The Senate seeks a preliminary vote, but getting it through before the recess remains difficult
The U.S. cryptocurrency market structure bill, the CLARITY Act, is again entering a crucial week of political back-and-forth in Washington. The latest reports indicate that the Senate still expects to schedule a preliminary vote before the summer recess on August 7, to test whether there is sufficient political momentum to move the bill forward to full Senate consideration. However, many observers believe that without a cross-party time agreement and adequate procedural coordination, the odds of getting the entire bill passed before the recess remain low.
The biggest challenge right now comes from limited procedural time and the 60-vote threshold. Even if a motion to end debate is filed this week, the earliest a preliminary procedural vote could take place would be a few days later. Further steps would still be required, including debate, amendments, and the final vote. Democrats, including lawmakers such as Elizabeth Warren and Chris Murphy, continue to have concerns about the bill’s contents. Within the Republican Party, disputes over the ethics provisions have also not been fully resolved. As a result, the CLARITY Act in the short term looks more like a stress test of political pressure than a near-term legislative breakthrough.

Bitcoin falls back below $64,000; a rebound in the short term meets resistance
Earlier, as the U.S.-Iran military standoff eased temporarily and the price of crude oil pulled back, Bitcoin ($BTC) briefly regained the $65,000 level, with market risk appetite recovering for a short period. However, as of the latest quote, Bitcoin’s price has retreated to $63,557, falling below the $64,000 psychological mark. This suggests that the rebound momentum from yesterday was unable to sustain, and that short-term bulls and bears have once again entered a standoff.

The key to this round of volatility lies in how quickly macro factors change. After the U.S. and Iran paused attacks on each other, WTI crude oil futures briefly dropped by about 5%, and Brent crude also fell noticeably. The market initially took this as a sign that inflation pressures were easing. However, crude oil had broken above $100 in the prior week, which has already heightened the market’s sensitivity to inflation and interest rates. Even if energy prices cool off in the short term, investors still don’t dare to chase prices aggressively.

The EU expands sanctions on Russia, adding 14 crypto platforms and 94 financial institutions
According to a Reuters report, on July 23 the European Union adopted its 21st round of sanctions against Russia, naming finance, energy, the military-industrial sector, and networks for sanctions evasion as the main targets. The latest measures add 218 individuals and entities to the list, including 48 individuals and 170 entities—one of the largest single additions by the EU in nearly four years.
EU High Representative for Foreign Affairs and Security Policy Kaja Kallas said the latest sanctions target more than 100 banks and crypto businesses, while also cracking down on Russia’s shadow fleet, refineries, and the military supply chain.

On July 24, 2026, SpaceX successfully carried out the 13th test flight mission of Starship (Starship Flight 13), achieving multiple key engineering milestones. This mission not only saw the successful return and ocean splashdown of the Super Heavy booster in the Gulf of Mexico, but also, for the first time during the space stage, successfully deployed 20 Starlink V3 satellites. After deployment into the orbit, the satellites completed solar array deployment and laser link tests while in the suborbital orbit. They also used the onboard camera to photograph the Starship heat shield from outside, providing brand-new data for rocket diagnostics.
Although the satellites were scheduled to burn up during reentry into the atmosphere 20 minutes later, the new-generation communications and orbital computation technologies had already been fully validated. The successful completion of this test flight marks an important milestone as the era of large-scale satellite deployment and space-based cloud computing moves forward.

Daily NK: Two major North Korean banking systems were infiltrated by a former military hacker from within the country
According to a report by Daily NK (run by defectors from North Korea), a criminal group made up of retired military hackers was recently discovered to have infiltrated the internal network systems of the North Korean Central Bank and the trading bank.
The hacker group converted the stolen national trading funds into cryptocurrency, and carried out large-scale smuggling of foreign currency in border areas. The National Intelligence Service of North Korea (formerly the Ministry of State Security) arrested and rounded up the group on July 12.
The Bank of Korea (North Korea) is responsible for issuing the nation’s currency and managing treasury funds, while the trading banks handle overseas payments and foreign-exchange transactions. Both are core units of North Korea’s financial system. This time, they were breached by an insider, shocking the Pyongyang authorities.

Keigo Higashino dies; colorectal cancer took the life of a generation of mystery novelist
Earlier today (7/27), the official account said that Japanese renowned mystery novelist Keigo Higashino passed away on July 23 due to colorectal cancer. He was 68 years old. His family has handled his arrangements through a family-only funeral.
Keigo Higashino, born in 1958 in Osaka, made his debut in 1985 with the mystery novel (After School) that won the Edogawa Rampo Award. He subsequently released the first installment of the “Detective Galileo” series, shaping the character of the genius physicist Manabu Yukawa—beloved for using his professional knowledge to solve mysteries. Among his most representative works, (The Devotion of Suspect X), published in 2005, won the Naoki Prize and the Honkaku Mystery Award, becoming one of his signature achievements.

As the Robinhood Chain draws a large influx of capital and meme-coin speculation continues to heat up, Robinhood CEO Vlad Tenev’s X account was reportedly hacked on Thursday. The compromised account was then used to post fake meme-coin promotional tweets in an attempt to mislead investors.
Robinhood subsequently confirmed that the Vlad Tenev account had been compromised and said it had deleted the related posts. The company added that it is working with the X platform to restore control of the account.
Fake official meme coin claims it will be listed on Robinhood
Tweets posted by the hijacked account introduced a token called Vladhood ($VLAD), claiming it is the “official mascot of the Robinhood Chain,” and asserting that the token will be listed for trading on the Robinhood App in the future.

Kiyosaki again issued a warning: U.S. debt is approaching $40 trillion
(Rich Dad Poor Dad) Author Robert Kiyosaki once again warned about the U.S. dollar and U.S. fiscal risks. In a recent post on the X platform, he said that U.S. public debt has nearly reached $39 trillion, and compared the current debt level with the period before the 2008 global financial crisis. At that time, U.S. public debt was about $9.5 trillion; today it has grown more than fourfold. The speed of debt expansion makes him believe the purchasing power of the dollar is facing greater pressure.
According to market-tracking data, U.S. public debt as of July 22 had reached approximately $39.64 trillion—only one step away from the $40 trillion mark.

China’s leading semiconductor memory chip maker ChangXin Storage (CXMT) was officially listed on the Shanghai Stock Exchange today (7/27). Its share price surged 472% on the first day, making it the largest listed enterprise of its kind in China. Through this initial public offering (IPO), the company raised RMB 66.6 billion (about $9.8 billion), setting a record for the second-largest IPO in China’s history, behind the Agricultural Bank of China in 2010.
Against the backdrop of strong demand for AI chips and China’s push for technological self-reliance, ChangXin Storage’s powerful debut not only reflects the market’s enthusiastic pursuit of the memory chip story, but also serves as an important benchmark for Beijing’s efforts to reduce reliance on foreign suppliers. Despite recent volatility in the semiconductor sector, analysts and institutional investors generally remain optimistic about its long-term growth potential.

NVIDIA invests US$1 billion in Naver to build AI data centers together
During the AI Summit in San Francisco, NVIDIA officially announced an investment of US$1.01 billion, subscribing to a third-party placement of newly issued shares by South Korean internet giant Naver. This gives NVIDIA about 4.5% equity and elevates it to become the company’s third-largest shareholder. Benefiting from this, Naver’s shares surged close to 10% at today’s (7/27) market close.
Both parties have teamed up with global asset management giant Brookfield to launch a large-scale expansion plan for South Korea’s “GAK Sejong” AI data center, with an expected investment of up to US$9 billion. The three parties will jointly build a sovereign AI cloud infrastructure capable of gigawatt (GW)-scale capacity, with services covering both South Korea and the United States.

Schiff questions STRC buying pressure; retail exits spark controversy
Gold supporters and long-term Bitcoin critics Peter Schiff have recently launched another attack, aiming at Strategy’s STRC preferred shares and the company’s capital model. The incident began after Strategy CEO Phong Le posted the latest STRC holder distribution on the X platform, noting that from March to July, the proportion of retail holders of STRC fell from 78% to 71%, while institutional investors’ participation kept rising. The average institutional holding size increased by 105%, reaching about $3.5 million.
Interpret these data as institutions adopting acceleration, and say that “the institution is stepping in.”

As BitMEX announced it was ending operations, the exchange and its founders were again hit by legal trouble. According to a report by Benzinga, a class-action lawsuit was filed on July 23 in the U.S. District Court for the Southern District of New York, alleging that BitMEX secretly operated an “insider trading desk” that directly bet against its own customers.
