FHE 就是你可以生产牛奶，而不需要知道是否存在 2 头牛。

1. ZK

你有一些牛奶。

你能证明这些牛奶来自2头牛，但你不知道具体是哪2头牛，也不知道它们是如何产奶的。

2. FHE（完全同态加密）

你有一个挤奶机。

你可以生产牛奶，而不需要知道是否存在 2 头牛。

3. MPC（多方计算)

你和你的邻居共同拥有 2 头牛。

你们各自可以挤奶，但谁也不知道自己挤的是奶牛的哪一部分。

4. TEE（受信执行环境）

你有 2 头牛。

你把它们养在一个安全的牛棚里，其他人无法进入。

牛只有在牛棚里才能挤奶。

On the Eve of the Tech IPO Boom, Polymarket Joins Forces with NASDAQ to Seize 'Valuation Authority'

At the dawn of a major tech IPO wave, prediction market platform Polymarket is forming an exclusive partnership with Nasdaq Private Market (NPM) to launch contracts predicting the valuations of pre-IPO giants like OpenAI, Anthropic, and SpaceX. This move aims to capture the "valuation adjudication right" in the booming but opaque private market, where accurate valuation data is scarce for retail investors. Facing stiff competition from rival Kalshi, which holds an 89% US market share and full regulatory approval, Polymarket's deal with NPM is a strategic counterattack. NPM provides crucial, real-time secondary market transaction data from employee stock sales to settle the new prediction contracts. In return, Polymarket's market-generated probability data becomes a valuable "institutional signal" for NPM's clients. This follows Polymarket's broader strategy of monetizing its prediction data through partnerships with giants like ICE (Intercontinental Exchange) and Dow Jones, integrating its signals into mainstream financial data feeds and media. The Nasdaq deal specifically targets the lucrative and high-profile arena of pre-IPO tech valuations, potentially raising the entry barrier for competitors in this niche.

Stop Blindly Clicking Confirm: Ethereum Wants You to Understand What You're Signing

The article criticizes the common practice of "blind signing" in Web3, where users confirm cryptographic transactions without understanding the content, typically presented as unreadable hexadecimal code. It introduces Ethereum's new initiative, "Clear Signing," as a solution aimed at making transaction signatures human-readable. Clear Signing, based on the ERC-7730 standard, allows protocols to provide standardized, structured metadata (like a "translation dictionary") that explains the semantic meaning of a transaction—such as "Swap 1,000 USDC for at least 0.42 WETH on Uniswap V3." This metadata is stored in a public registry for wallets to fetch and display in plain language, moving beyond mere structured data formats like EIP-712. The article clarifies that Clear Signing is not an instant fix but a foundational infrastructure shift that requires widespread adoption by protocols and wallet support. It complements, rather than replaces, existing wallet security features like transaction simulation. The initiative represents a crucial step toward genuine user sovereignty by restoring informed consent, making blockchain accessible to non-technical users and addressing a long-standing security and usability debt in the ecosystem.

Can Alibaba Cloud Rewrite Itself?

Over the past five months, Alibaba Cloud's MaaS (Model as a Service) revenue has surged 15x, marking a strategic overhaul where the company is shifting its 17-year-old system designed for "humans using cloud" to a new paradigm centered on "Agents consuming Tokens." At its recent summit, Alibaba Cloud announced a full-stack upgrade encompassing "chip-cloud-model-inference," all optimized for AI Agents. Key launches include the new AI product portal "QianWen Cloud," hyper-node servers powered by the in-house AI chip Zhenwu M890, and the latest flagship model, Qwen3.7-Max. Senior VP Liu Weiguang described this as building "China's largest AI factory," where chips are raw materials, the cloud is the workshop, models are machines, and the inference platform is the assembly line, with Tokens as the final product. The company is now emphasizing its chip strategy, unveiling the Zhenwu M890 and a two-year roadmap for future chips. With over 560,000 chips deployed across 400+ clients, Alibaba Cloud aims to control the marginal cost per Token, mirroring Google's integration of TPU and Gemini for optimal cost-performance. The cloud infrastructure itself is being rewritten. Traditional cloud interfaces are being transformed into standardized, Agent-callable Skills. A new scheduling logic focuses on "task scheduling" over "resource scheduling" to handle the unpredictable, elastic workloads of Agents. Liu noted that AI applications now automatically provision cloud resources, with one customer's daily automated provisioning equaling two weeks of manual work. For models, the focus has shifted from conversational prowess to execution capability. Qwen3.7-Max demonstrated this by autonomously writing and optimizing a production-grade AI compute kernel for the new Zhenwu M890 chip over 35 hours, achieving a 10x performance improvement. The underlying Bailian platform was upgraded for efficiency, and it maintains an open ecosystem, hosting third-party models. This restructuring extends beyond technology to sales, organization, and metrics. Alibaba Cloud has established dedicated MaaS sales teams, separated from traditional IaaS, with new KPIs focusing on high-quality Tokens that solve real problems, the number of core business systems integrated with models, and the efficiency of Agent task completion. The underlying bet is clear: AI represents an opportunity orders of magnitude larger than before. Despite the uncertainty, Alibaba Cloud is aggressively rebuilding its entire system, betting on an AI-driven future where Tokens could become its largest product line.

Those Who Rushed into SpaceX's Private Secondary Market Are Bewildered in the Greatest Wealth Creation Wave Ever

Investors are rushing into SpaceX’s private secondary market ahead of its historic IPO, but many are finding confusion instead of clarity. While early backers like Darsana Capital are poised for astronomical returns—turning a $600M bet into roughly $150B—other buyers face uncertainty about whether they actually own SpaceX shares at all. The frenzy stems from AI-driven FOMO, as soaring valuations for private companies like OpenAI and SpaceX create intense demand for pre-IPO exposure. This has fueled a booming but opaque secondary market, where special purpose vehicles (SPVs) layer investments, adding fees and obscuring ownership. Some investors are three or four layers removed from the actual stock, unable to verify their holdings. With companies staying private longer—SpaceX for 24 years—secondary trading has grown complex and risky. Platforms have faced fraud, bankruptcy, and regulatory scrutiny. Now, firms like Anthropic and OpenAI are publicly rejecting unauthorized transfers, warning that shares sold through certain platforms may be invalid. SpaceX’s IPO filing in June will finally reveal the official shareholder list, resolving these uncertainties. Until then, buying into SpaceX through secondary channels remains a high-stakes gamble—a blind box in a market overflowing with capital and complexity.

Warsh's First Conundrum: Rate Cuts, Inflation, and a Fractured Fed

Walsh's First Dilemma: Rate Cuts, Inflation, and a Divided Fed Kevin Warsh officially assumed the Fed Chairmanship on May 15th, inheriting a central bank deeply divided over inflation. Contrary to market expectations of a dovish stance due to his appointment by President Trump, Warsh's historical record shows early and consistent hawkish concerns about inflation. The Fed he leads is fractured, with three FOMC members recently dissenting against even hinting at future rate cuts. The immediate challenge is surging inflation. While the Iran-related oil shock is a temporary factor, core CPI and services inflation are accelerating, showing signs of becoming entrenched—echoing the Fed's 2022 "transitory" misstep. Warsh faces the task of building consensus within a committee where several members believe policy may not be restrictive enough, especially if the neutral interest rate (r-star) is higher than currently estimated. Politically, Warsh is caught between Trump's desire for rate cuts and the economic reality of persistent price pressures. Any move perceived as bowing to political pressure could undermine Fed independence. Market implications are significant. Long-term Treasury yields (e.g., 30-year at 5.19%) could rise further, especially if the June FOMC statement hints at possible tightening. Tech stocks face continued valuation pressure from higher rates. The key variable is progress in Iran negotiations; a breakthrough before the June meeting could temporarily ease oil-driven inflation, but stubborn services inflation would remain. All eyes are on Warsh's first post-FOMC press conference on June 17th. His wording on inflation and policy will reveal how much the market has mispriced his stance and the Fed's likely path forward.
