Overturning the Mainstream Approach to Hallucinations: Metacognition is the New Solution for Large Models to Break the Hallucination Barrier

This paper, "Hallucinations Undermine Trust; Metacognition is a Way Forward," proposes a paradigm shift in combating AI hallucination. It argues that the current mainstream approaches—striving for omniscience by scaling data/models or having AI abstain from uncertain answers—are fundamentally flawed. The former has inevitable knowledge gaps, while the latter imposes a crippling "utility tax," requiring the rejection of many correct answers to achieve high accuracy, due to models' poor "discrimination" (the ability to distinguish correct from incorrect answers internally). The core contribution is redefining hallucination not as "being wrong," but as "expressing false information with unwarranted certainty." The proposed solution is **Faithful Uncertainty** or **Metacognition**: enabling AI to accurately perceive its internal uncertainty and honestly express it in its language (e.g., using hedging phrases when unsure). This creates a more reliable assistant that provides useful information while signaling its confidence, minimizing harm from errors. The paper emphasizes that metacognition is critical for the era of AI Agents. Without it, Agents cannot intelligently decide when to use tools like search engines, leading to inefficiency and misuse. Key implementation challenges are highlighted: the "bootstrapping paradox" of training with static uncertainty data, the "alignment distortion signal" where human preference training suppresses internal uncertainty cues, and the difficulty of causally evaluating true metacognition vs. its superficial imitation. The paper concludes that the goal should not be an infallible AI, but one that is honest about the limits of its knowledge, thereby building user trust through transparent communication of its certainty.

When Futu Turns into a Matchmaking Corner: Overseas Identity Becomes the Hard Currency for the Middle Class

When Futu Becomes a Matchmaking Corner: Overseas Status as the New Hard Currency for China's Middle Class Following a severe penalty announcement from Chinese regulators on May 22nd targeting offshore brokerages like Futu, its app community unexpectedly transformed into an impromptu matchmaking platform. Users posted相亲 (matchmaking) requests, explicitly seeking partners with overseas residency or citizenship, revealing a stark new reality: for China's middle class, an overseas identity has become a crucial asset. The regulatory crackdown, which restricts mainland Chinese residents from opening new accounts to buy overseas securities like US stocks, has sharply escalated the value of a foreign passport or permanent residency. This status now acts as a gateway to global asset allocation—including US equities, offshore property, and foreign currency deposits—effectively becoming a new form of "hard currency." Its scarcity, non-transferability (except through marriage, inheritance, etc.), and role as a hedge against domestic uncertainty have driven its premium. The article traces the evolution of how China's middle class views overseas resources: from an investment for opportunity (2000s), to risk diversification (2010s), and now to a mandatory "insurance policy" for financial access. With the regulatory window closing for many, the demand is shifting towards securing such status for the next generation through international education. The surreal scene of high-performing investors posting dating resumes underscores a 2026 where financial talent can be secondary to the right passport.

From Tencent and Circle: Looking at the Easy and Hard Questions of Investment

The article contrasts the investment prospects of Tencent and Circle in the AI era, framing the decision as a choice between "easy" and "hard" problems, inspired by Charlie Munger's philosophy. Tencent's stock has declined despite strong earnings, as the market shifted from fearing insufficient AI investment to worrying about excessive spending. The author argues this pessimism is overdone. WeChat's nascent AI agent, Yuanbao, is seen as a prototype for a future, more powerful system-native agent. Crucially, this agent would have system-level permissions to seamlessly interact with the massive Mini Program ecosystem (housing apps like Meituan, Didi, etc.), making it a practical, usable product for billions. The author believes the high-probability success of this inevitable development makes investing in Tencent an "easy" decision that the market is currently overlooking. Conversely, Circle's recent rise is fueled by the AI narrative, specifically the belief that AI agents will require blockchain-based stablecoins for settlement, with USDC as the leading compliant option. The author deconstructs this bullish thesis, identifying high uncertainties in its core assumptions: whether AI transactions will *necessarily* use stablecoins (vs. other protocols like Google's UCP), USDC's ability to maintain its lead against competitors like Tether or PayPal, and whether stablecoins even possess strong network effects in an agent-dominated world where cost and friction are paramount. The compounding uncertainty makes investing in Circle a "hard" problem, riskier than market sentiment suggests. In summary, the author posits that Tencent presents a clear, high-probability opportunity (easy), while Circle's future is built on a chain of speculative assumptions (hard).

Fed holds rates steady at 3.5%–3.75% as projections signal slower path to easing

The Federal Reserve maintained interest rates at 3.5%–3.75% on 18 March, signaling that inflation remains too high to justify near-term cuts. Policymakers emphasized that inflation is still above the 2% target despite a solid economy and stable labor market. The Fed's updated economic projections indicate a delayed easing cycle, with PCE inflation expected at 2.7% in 2026 and the federal funds rate around 3.4% the same year. This reinforces a "higher-for-longer" narrative. Geopolitical risks were also noted as a potential source of uncertainty. For crypto markets, the lack of immediate rate cuts may limit liquidity, but the soft-landing narrative remains supportive over the medium term. Markets will now focus on incoming data to gauge the timing of policy easing.

Gold Gains as a Safe-Haven while Cryptocurrencies Fumble

Gold has strengthened as a safe-haven asset amid global uncertainty, rising 0.8% to over $5,190 per ounce, while the US Dollar's performance further supports its appeal. Silver also saw significant gains. In contrast, cryptocurrencies experienced volatility but recovered slightly, with Bitcoin up 3.24% and Ethereum gaining 5.17%, though both remain highly volatile. Market uncertainty is driven by geopolitical tensions and new tariff policies. Investors are advised to conduct thorough research before investing in any asset.

Stronger US Dollar and Weakening Cryptocurrencies, Also Extends to Gold

The US dollar has gained strength, with the US Dollar Index rising 0.11% in a single day. This has coincided with a downturn in cryptocurrencies, with the total market cap falling 3.06% to $2.19 trillion and Bitcoin dropping below $64,000. The precious metal gold also declined, slipping over 1% in value. Major US stock indexes, including the Nasdaq and Dow, fell as well. Analysts attribute these market movements to factors such as geopolitical tensions, macroeconomic shifts, and investor uncertainty. However, these effects are believed to be short-term and may reverse as conditions stabilize.

Uncertainty is Dominating Global Trade and Crypto Market is Feeling the Heat

The US Supreme Court's decision to strike down tariffs imposed by former President Donald Trump has heightened uncertainty in global trade, with experts noting a lack of clarity in future trade dynamics. This uncertainty is mirrored in the crypto market, where bearish sentiment prevails. The Crypto Fear & Greed Index has dropped to 11, and the total market capitalization fell 3.37% to $2.18 trillion, with significant liquidations recorded. Bitcoin and Ethereum have both declined over the past week, trading at $63,187.61 and $1,828.01, respectively. Additionally, both Spot Bitcoin and Ethereum ETFs experienced outflows, reflecting broader market caution. The overall sentiment remains tense as traders monitor ongoing developments.

US Supreme Court Has Clipped Trump’s Wings, But Uncertainty Remains for the Crypto Market

The US Supreme Court has reduced President Trump's tariff authority, lowering rates from 15% to 10%, but global uncertainty persists. This has negatively impacted the crypto market, with Bitcoin to fall below $65k and the total market cap nearing $2 trillion after a 4.43% drop. Market volatility remains high, and a correction is anticipated. In contrast, Gold and Silver have gained positive momentum as alternative investments. Experts warn that uncertainty continues to influence economic forecasts and investment decisions.

Bitcoin Traders Show Caution With Leverage As Market Uncertainty Spikes – Details

Bitcoin traders are exhibiting increased caution by reducing leverage in futures markets, as macroeconomic and geopolitical uncertainties rise. According to CryptoQuant analyst Darkfrost, the Estimated Leverage Ratio on Binance has declined from 0.19 to 0.15 in February, accompanied by a significant drop in open interest. This deleveraging reflects a strategic risk management approach rather than panic, as Bitcoin reserves remain stable. Factors contributing to this risk-off sentiment include new tariff announcements, geopolitical tensions, weaker-than-expected US economic growth, and rising inflation. While reduced leverage may cause short-term selling pressure, it lowers systemic risk and supports healthier price discovery. Bitcoin is currently trading near $67,965 with a modest weekly gain.

Less Than a Year in Office and Leaving Again: Why Are Core Figures of the Ethereum Foundation Departing Once More?

Tomasz Stańczak, the co-executive director of the Ethereum Foundation (EF), has announced his resignation, just 11 months after taking the role. He was appointed alongside Hsiao-Wei Wang in March 2025, replacing long-time leader Aya Miyaguchi amid community criticism that EF was too slow and disconnected. Stańczak, founder of core Ethereum client Nethermind, was brought in to make EF more decisive and execution-focused. During his tenure, he streamlined operations, refocused strategy on Layer-1 scaling, accelerated upgrade timelines, and pushed new initiatives in AI integration and privacy. His departure hints at internal tension. In his statement, Stańczak suggested his ability to operate independently within EF diminished as the leadership became more self-sufficient. He expressed a desire to return to hands-on product building, specifically in AI/blockchain convergence, echoing Ethereum’s early experimental spirit. He is replaced by Bastian Aue, a low-profile internal figure focused on "principled" decision-making aligned with "cypherpunk values," signaling a potential shift back towards a coordination-focused rather than execution-driven approach. This leadership change comes at a critical time. EF is preparing to release key proposals on "Lean Ethereum" and future roadmaps, while Ethereum faces intense competition, Layer-2 fragmentation, and market pressure—with its price risk falling below inflation-adjusted 2018 levels.
