Analysis: US Government Restrictions on Foreign Nationals Accessing Anthropic's Latest Model Could Impact Its IPO Outlook
June 13 — According to a report from Fortune, Anthropic has completely shut down access to its latest AI models, Fable 5 and Mythos 5. The move follows the U.S. Department of Commerce invoking national security export control rules to bar the firm from granting access to any foreign national. The order applies not only to people outside the U.S., but also to non-U.S. citizens residing within the country, plus Anthropic’s own non-U.S. national employees.
Anthropic said the directive’s broad scope left it with no other option than disabling access to those models for all users. However, less powerful models like Claude Opus 4.8 remain unaffected.
The policy has sparked fierce pushback across the AI industry and among policy experts. Some frame it as another punitive step from the Trump administration against Anthropic. The Trump White House had earlier ordered federal agencies to stop using Anthropic’s models and labeled the company a "supply chain risk."

X-Agent: Building an Agentic AI Application Layer for Individual Creators, Developers, and Communities
On June 13, X-Agent, in partnership with Sentient, Alibaba, Fudan University, and other collaborators, hosted the Open AGI Developer Day at Fudan Science and Technology Park in Shanghai.
During the event, Prime Xiao, X-Agent’s Engineering Director, shared the company’s product vision: X-Agent is focused on building an Agent Application Layer for individual creators, developers, and the community, enabling Agent Apps to be created, deployed, run, distributed, and monetized. The team believes that an Agent App should not only connect business states, call external tools, and complete tasks within clear bounds, but also be discoverable and adopted by real users after launch, forming a closed business loop centered on usage and task fulfillment.
Xiao further emphasized that X-Agent is far more than an AI coding tool—it is an end-to-end platform linking Builder, Runtime, Payment, and Distribution functions, helping Agent Apps transition from proof-of-concept demos to viable products, and

Top Cryptographers Disagree on Bitcoin's Quantum Risk Significance Issue, But Recommend Immediate Initiation of Post-Quantum Signature Planning
June 13: The Cryptography Advisory Council, convened by Coinbase, has stated that quantum computers don’t pose an immediate threat to blockchains—but the Bitcoin community should immediately begin planning for post-quantum signatures. Council members include top cryptography experts like Scott Aaronson of the University of Texas at Austin, Stanford’s Dan Boneh, and Justin Drake of the Ethereum Foundation.
The report identifies that Bitcoin’s quantum risk is concentrated in early addresses: around 1.7 million BTC are held in roughly 20,000 early public key addresses, where owners’ public keys are publicly posted on-chain, leaving them vulnerable to future quantum attacks. Many of these addresses are believed to belong to Bitcoin’s anonymous creator Satoshi Nakamoto or holders who lost their private keys, so their funds can’t be moved proactively to more secure wallets. Project11’s research adds that another ~5 million BTC face potential risk from address reuse, though most of these are
