AI Agent Economy Accelerates with Key Infrastructure Launches. In a significant week for AI agents, Sam Altman's Worldcoin launched AgentKit, enabling AI agents to carry cryptographic proof of human identity, with 17.9 million users verified. On the same day, the protocol integrated with the x402 system from Coinbase and Cloudflare, allowing agents to perform micro-payments using stablecoins autonomously. Nvidia further solidified the infrastructure by releasing its Retail Agentic Commerce Blueprint, a full implementation of OpenAI's commerce protocol, enabling AI models like ChatGPT to handle entire shopping journeys. Industry projections suggest agent-driven commerce could reach $3-5 trillion by 2030. In other news, major tech industry associations filed a legal brief supporting Anthropic in its dispute with the Pentagon over the right to restrict government use of its AI. The Fed's March meeting concluded with rates held steady, while rising energy prices from the Iran conflict cloud the inflation outlook. Nvidia also unveiled its AI Grid, aiming to repurpose telecom networks into distributed推理 grids, and announced DLSS 5, a major graphics leap for 2026. The ongoing Iran war continues to strain global budgets and supply chains, with costs estimated between $40-95 billion.

On the same day, Sam Altman's World and Coinbase integrated identity verification and stablecoin payments into the AI Agent pipeline, while NVIDIA released the full implementation of the Agent e-commerce protocol on the second day of GTC. The Agent economy moved from concept to infrastructure in just one week.

1|AI Agent Got Its ID and Wallet on the Same Day

World released AgentKit, enabling AI Agents to carry cryptographic credentials proving "a real person is behind it" through zero-knowledge proofs, with 17.9 million users globally already verified. On the same day, AgentKit integrated with the x402 protocol jointly developed by Coinbase and Cloudflare, allowing Agents to perform micro-payments using stablecoins without human intervention. Erik Reppel, Engineering Lead of Coinbase's Developer Platform, stated: "Payment is the how of Agent commerce, identity is the who."

NVIDIA added the third pillar on the second day of GTC: the Retail Agentic Commerce Blueprint, a full implementation of OpenAI's Agentic Commerce Protocol, also compatible with Google's Universal Commerce Protocol. Consumers using ChatGPT or Gemini can theoretically complete the entire process from search to payment through an Agent. World cited predictions that Agent commerce could reach $3 to $5 trillion by 2030. The identity layer, payment layer, and commerce protocol layer all landed in the same week, and the infrastructure for the Agent economy is taking shape faster than anyone expected.

2|The Entire AI Industry Stands Behind Anthropic

Four major tech industry associations (CCIA, ITI, SIIA, TechNet) submitted amicus briefs to the court, requesting a halt to the Pentagon's designation of Anthropic as a "supply chain risk." These four associations represent Google, OpenAI, Meta, Microsoft, NVIDIA, Adobe, Cloudflare, Accenture, and Deloitte. Hearing scheduled for March 24.

The issue arose when Anthropic requested that the U.S. military commit not to use its models for fully autonomous weapons and large-scale domestic surveillance. The Pentagon's move was to label it as a supply chain risk, a designation historically reserved for foreign adversaries. Anthropic expects revenue losses to reach billions of dollars by 2026.

On the surface, it's a contract dispute between a company and the military, but at its core is a question that has never been formally answered: Do AI companies have the right to set limits on how government clients use their technology? The entire industry gave its answer with a court filing.

3|Powell's Second-to-Last Appearance, Iran War Weighs on Inflation Expectations

The FOMC March meeting concludes today, with the interest rate decision and dot plot to be announced at 2:00 AM Beijing time tomorrow. The market expects rates to remain unchanged at 3.5%-3.75%, with the CME FedWatch tool showing a probability of over 92% for no change. The suspense lies not in the rate itself, but in the dot plot: the median expectation in January was for only one cut this year, and rising energy prices due to the Iran war could further reduce that number.

Powell's term ends on May 15. This is his second-to-last press conference as Fed Chair. The Strait of Hormuz blockade, soaring oil prices, and resurgent inflation expectations all weigh on his final two press conferences. Every word he says about inflation today will be parsed meticulously.

4|NVIDIA Aims to Rewrite Telecom Networks into Inference Grids

On the second day of GTC, NVIDIA released the AI Grid architecture, transforming operators' base stations, central offices, and edge nodes into a distributed inference grid. Comcast benchmark tests: distributed deployment reduced inference costs by 76% compared to centralized deployment, with P99 burst traffic latency below 500 milliseconds and peak throughput of 42,000 tokens per second. Nokia and T-Mobile are already cooperating on AI-RAN implementation. A unified control plane automatically routes workloads based on latency, data sovereignty, and cost.

The story Jensen Huang told on Monday was about selling GPUs to data centers; the story on Tuesday was that the entire telecom infrastructure is an inference engine. From chips to operating systems to grids, this front is growing longer every day.

5|Day 18 of the Iran War, the Pentagon's Budget Gap is Widening

According to CSIS estimates, the first 100 hours of Operation Epic Fury cost $3.7 billion, with a daily cost approaching $900 million. Budget experts'预估 (estimate) for the total direct military expenditure of the entire war ranges from $40 billion to $95 billion, most of which is not covered by the existing defense budget. The Pentagon will soon need to request additional funding from Congress. The Strait of Hormuz has been closed for three weeks, and the UN World Food Programme warns the war is driving up global food and fertilizer prices.

Iran has chosen to attack neutral and friendly countries (Oman, Qatar, Turkey), and the UK's Cyprus air base was hit by a drone. The conflict has spread to at least 12 countries. RAND's assessment is: Iran is more likely to choose to continue fighting rather than concede, and the trajectory of the war may be longer than Washington expects. The cost curve and timeline of this war are both spiraling out of control.

Near Returns to the AI Stage: Transformation into a Public Chain Due to 'Payroll Difficulties,' Agent and Privacy Emerge as New Growth Narratives

NEAR Returns to AI Origins: From Payroll Struggles to Blockchain, Now Focusing on AI Agents and Privacy NEAR Protocol's journey began not with grand blockchain ambitions, but from a practical hurdle: its AI startup founders, including Transformer paper co-author Illia Polosukhin, couldn't efficiently pay international developers in 2017. This led them to pivot and build a high-performance, scalable blockchain. After years navigating various crypto narratives like sharding and cross-chain interoperability, NEAR is now leveraging its AI roots to re-enter the AI arena. A key driver is its "NEAR Intents" layer, which abstracts complex cross-chain transactions. Users simply state their goal (e.g., swap BTC for ETH), and a solver network finds the optimal route. This system has processed over $20B in cross-chain volume, generating significant fee revenue. A major growth area is private transactions via "Confidential Intents/Swaps," which hide trade details until settlement to protect against MEV and front-running. Remarkably, private swaps recently accounted for over 40% of NEAR's transaction volume, highlighting strong demand but also potential regulatory scrutiny. With its AI-founder pedigree, NEAR is positioning itself at the intersection of blockchain, AI agents, and privacy, aiming to become infrastructure for the emerging agent economy while navigating the challenges of its rapid adoption.

From Ethereum to AI's 'CROPS': What Exactly is This Set of 'Slow Variables' That Vitalik Repeatedly Emphasizes?

In recent discussions, Vitalik Buterin has frequently emphasized the concept of "CROPS," a framework defining core values for Ethereum's development. CROPS stands for Censorship Resistance, Capture Resistance, Open Source, Privacy, and Security. Initially outlined in the Ethereum Foundation's "EF Mandate," it represents a commitment to user sovereignty, ensuring that the network resists external control, remains open, protects privacy, and prioritizes security. The relevance of CROPS extends beyond Ethereum's foundational principles, becoming crucial in the context of AI integration. As AI agents begin handling wallet operations and automated transactions, the risk increases that users may cede control over their digital assets, privacy, and intentions to centralized AI service providers. A "CROPS AI" would therefore emphasize local execution where possible, privacy-preserving remote model calls (e.g., using zero-knowledge proofs), and transparent, verifiable processes to maintain user agency. Vitalik highlights a significant convergence between "CROPS Ethereum access layer" and "CROPS AI." Both address the same fundamental challenge: how users can access powerful services—be it blockchain data via RPCs or AI models—without exposing sensitive information or relinquishing ultimate control. This intersection points toward a future digital entry point that is more private, secure, and user-controlled. Ultimately, CROPS is not merely an abstract ideal but a practical guidepost. It steers development—from protocol resilience and wallet design to AI agent safety—towards a future where users retain self-sovereignty even as digital systems grow more complex and powerful. In an era of accelerating AI adoption, these "slow variables" of censorship resistance, openness, privacy, and security may define Ethereum's enduring value.

Zcash Bug Could Have Minted Unlimited ZEC Undetected

A critical vulnerability in Zcash's Orchard shielded pool, discovered by researcher Taylor Hornby on May 29, 2026, could have allowed an attacker to create an unlimited amount of undetectable counterfeit ZEC. The flaw, involving an under-constrained element in the Orchard circuit, existed from the pool's 2022 activation until an emergency fix was deployed by June 2, 2026. Hornby identified the bug using AI-assisted auditing tools and confirmed its exploitability in a test environment. Due to Orchard's privacy features, which hide transaction amounts and history, there is no cryptographic way to prove whether the vulnerability was exploited before the fix. While Shielded Labs assesses prior exploitation as unlikely, this uncertainty has sparked a debate on proving supply integrity in privacy-preserving systems. In response, Shielded Labs and other developers are exploring a network upgrade, potentially involving a new shielded pool and formal verification of the circuit rules to prevent future vulnerabilities and allow verification of the ZEC supply's integrity. ZEC's price fell nearly 45% following the disclosure.

Silicon Valley 'Startup Guru' Steve Hoffman: Web3 + AI Could Be a Trap

Silicon Valley investor and "Godfather of Startups" Steve Hoffman warns that combining Web3 with AI is likely a trap, not a promising venture. In an interview, Hoffman argues that while AI is a foundational technology touching all industries, Web3 adds complexity, friction, and regulatory risk without solving mainstream consumer or business needs. He advises founders to focus on deep, specialized applications where startups can out-iterate giants, rather than on generic features easily replicated by large tech companies. Hoffman observes that Silicon Valley will lead foundational AI research, while China excels at rapid, large-scale application and commercialization, particularly in robotics. He stresses that AI-driven autonomous agents capable of collaborative, multi-step tasks are 2-4 years away, which will cause significant job displacement. The solution is not to slow AI but to redesign business models around human-AI collaboration and reform social systems like education and retraining. For startups, Hoffman recommends focusing on vertical, expertise-heavy domains to build defensibility. He sees major opportunities in AI fraud detection and cybersecurity. Key founder mindsets include systemic thinking over feature-focus, relentless customer centricity, building adaptive teams, and deeply understanding AI's capabilities and limits. Hoffman is also leading a non-profit initiative to establish university centers aimed at training future leaders in responsible, human-value-aligned AI innovation.

Token Inefficient, Economy Tokenless

The article "Tokens Aren't Economical, Economics Aren't Tokenized" analyzes a pivotal shift in the AI industry from a technology-driven narrative to one dominated by capital efficiency. It highlights two concurrent trends: a severe capital shortage due to the exorbitant and recurring costs of compute (e.g., OpenAI's high burn rate) and a wave of corporate spin-offs where major tech companies are separating their AI units (like Kuaishou's Kling and Baidu's Kunlunxin). The core argument is that AI's "anti-internet" business model, where user growth increases costs rather than profits, has created a disconnect between high valuations and actual cash flow. Spin-offs address this by allowing AI assets to be valued independently. Within a parent company, they are seen as cost centers, but as standalone entities, they are priced based on their growth potential and scarcity in the primary market, leading to massive valuation premiums (e.g., Kling's estimated value tripling post-spin-off). The industry is at an inflection point, moving from "model worship" to "value realization." The competition is evolving from a pure compute (GPU) race to a broader focus on systemic efficiency and full-stack engineering (involving CPUs and orchestration) to achieve viable commercialization. The year 2026 is framed as a critical moment where the industry must definitively answer how to economically translate AI capability into tangible business value, reshaping the sector's future power structure.
