Anthropic announced that the Claude Mythos Preview model has made breakthroughs in cryptographic research, discovering improved attack methods against the post-quantum digital signature candidate HAWK. HAWK is a post-quantum signature candidate solicited by NIST to combat quantum computer attacks, which has already passed two rounds of expert review. However, Claude reduced the effective key strength of HAWK-256 from 2^64 to 2^38 in just 60 hours, significantly lowering the theoretical cost of cracking. HAWK has not yet been deployed in practice, and this attack currently does not affect any production systems.Claude also discovered an improved attack against 7-round AES, achieving a speed increase of 200 to 800 times. During the research process, Claude independently completed literature reviews, mathematical reasoning, and experimental validation with limited guidance from cryptographers. The HAWK attack took about 60 hours and had an API cost of approximately $100,000; the AES attack was completed independently by Claude, which generated about 1 billion tokens before proposing core innovative ideas. Anthropic researchers then spent hundreds of hours validating the results. Anthropic stated that AI models can now help identify significant flaws in cryptographic algorithms, and the cryptography community may face bottlenecks similar to those in the software vulnerability field—AI-generated research results far exceed human verification capabilities. Anthropic has collaborated with academic institutions to launch the CryptanalysisBench benchmark and coordinated disclosures with NIST authors and government partners. The research team has achieved preliminary results on algorithms such as LEA and Serpent-128. Anthropic warns that as AI capabilities improve, actual attacks against deployed systems may be discovered in the future, necessitating the establishment of response mechanisms in advance.

According to crypto user @HowardLouisHL, on June 30, 2026, he deposited 100,000 USDT into Ourbit and engaged in normal trading for about a week. On July 4, when he attempted to withdraw to Binance, the system prohibited the transaction. Customer service only replied, "Triggered risk control," without specifying the exact reason. The next day, the user's account was restricted from logging in. After being forced to submit all identity and account information, on July 20, he received an official email from Ourbit stating that the review had been postponed to July 3, 2027, and declared that "it may be extended again without reason."The user made three demands: to publicly disclose the specific risk control reasons, to provide a clear timeline for handling, and to immediately unfreeze and return the 100,000 USDT.As of now, Ourbit has not issued a public response regarding this incident.

Founder of Strategy, Michael Saylor, tweeted that attempting to modify Bitcoin rules simply because one does not agree with how others use Bitcoin is a nationalist impulse, which is contrary to the freedom, property rights, free market, and Austrian economics spirit upheld by the Bitcoin community.He bluntly stated that BIP 110 essentially enforces "monetary purity" through statutory means, which does not align with the core principle of Bitcoin's decentralization.

Coinbase CEO Brian Armstrong posted on X in response to the recent controversy sparked by his profile picture change and the voices from the Base community feeling insufficiently supported. Armstrong made it clear that his personal X account should not be viewed as investment advice or a signal source for individual tokens; he simply shares content online that he finds interesting or funny, and he may not be aware of whether the content relates to a specific token or project. His posts and profile picture do not constitute endorsement or commitment.Armstrong pointed out that Base is committed to building financial services infrastructure, covering tokenized stocks, lending protocols, stablecoin payments, and even meme coin trading. He supports economic freedom and user freedom to trade, but treating his X account as a trading signal is a risk users must bear, which also goes against his own wishes. Regarding support from the Base team or Coinbase, Armstrong stated that many tokens cannot be listed on centralized exchanges due to compliance and regulatory reasons, "If you hope Jesse or I can help pump or call certain tokens, we will not do that."The ways Coinbase has committed to support include hosting offline Base Batches events, providing funding to promising developers, investing in quality projects through Coinbase Ventures and the Base ecosystem fund, and regularly integrating promising Base DeFi protocols into Coinbase products. Currently, the post has over 1.05 million views.

Founder of Strategy Michael Saylor published a post opposing the BIP 110 proposal that restricts the use of inscriptions and other data storage purposes. Bitcoin should adhere to neutrality, open markets, and permissionless innovation, and should not target specific uses through consensus rules.Saylor listed 110 reasons for opposition, emphasizing that Bitcoin should remain conservative at its core. Bitcoin does not need guardians of purity; it needs guardians of neutrality.

Binance's originally scheduled launch of Aerodrome (AERO) on July 17, 2026, at 19:00 will be postponed to July 18, 2026, at 00:00. Users can pay attention to subsequent announcements for specific trading pair information.

Trump Media (TMTG) announced on Thursday the launch of a paid Truth API, providing institutional clients with the fastest real-time access to the most market-influential accounts on the Truth Social platform (including U.S. President Trump). The target clients are high-frequency and algorithmic trading firms, with plans to open to institutional clients starting August 1.Interim CEO Kevin McGurn stated that the market has already been fluctuating due to Truth Social posts, and this API offers a direct, authorized real-time machine-readable data stream, while advancing the company's strategy to monetize proprietary assets through high-margin recurring revenue streams. Trump's Truth Social posts have previously triggered market fluctuations, with recent examples including his posts regarding the U.S.-Iran conflict.McGurn also mentioned that some companies have attempted to scrape Truth Social data in violation of rules, and we will create significant friction for those who do not obtain data directly from us. Other major accounts on Truth Social include Donald Trump Jr., Eric Trump, and FBI Director Kash Patel.

According to Bits.media, Anatoly Aksakov, chairman of the Financial Market Committee of the State Duma of Russia, stated that the second and third readings of the criminal liability bill for illegal cryptocurrency transactions will be postponed until the new State Duma is reviewed. The reason is that the Duma's spring session will end on July 27, and there will be an election recess from August to September, with the Duma election voting ending on September 20. Therefore, the review will not resume until the autumn session at the earliest.The bill completed its first reading in early July, with a maximum penalty of 7 years in prison for organizing illegal cryptocurrency circulation. The relevant penalty provisions are proposed to officially take effect on July 1, 2027. Under the current regulatory framework, Russian citizens can only buy and sell cryptocurrencies through institutions holding a license from the Central Bank of Russia, and P2P and over-the-counter transactions may face criminal liability. Aksakov denied concerns that the bill would affect cryptocurrency exchanges and P2P users, stating that the related worries are "unfounded." Meanwhile, another Russian government initiative to strengthen state control over cryptocurrencies, the "Digital Currency and Digital Rights Law," has also been postponed, with the original timelines for implementation in July and September now missed.

The UK's HM Revenue and Customs has confirmed that depositing crypto assets into DeFi lending protocols and liquidity pools will no longer be considered a taxable disposal, and capital gains tax will be deferred until the investor actually economically disposes of the asset. This measure was announced on Monday and will take effect on April 6, 2027, amending the 1992 Taxation of Chargeable Gains Act. HMRC estimates that this measure will affect approximately 700,000 individuals and trustees using crypto loans and liquidity pools. Aave founder Stani Kulechov stated that this practice is "the right direction."

According to Jinshi reports, traders have postponed their bets on a Federal Reserve interest rate hike until October.

According to the official announcement from NEAR Chain Status, the NEAR mainnet version 2.13.0 has been released, introducing post-quantum transaction signature schemes and dynamic sharding features.Voting will begin at 8:00 AM Beijing time on July 20. Former NEAR core developer Vadim introduced that this upgrade includes features that would typically require a ten-year roadmap for most blockchains: the post-quantum signature ML-DSA-65 becomes the third key type in the protocol after ed25519 and secp256k1, allowing accounts to hold keys that cannot be forged by quantum computers, with only a 32-byte hash recorded on-chain; dynamic sharding enables the chain to automatically monitor the status and size of each shard and to split and re-shard at epoch boundaries without the need for protocol upgrades or manual intervention; Gas Keys provide critical functionality for the proxy economy, allowing a single account to run a batch of proxies to send transactions simultaneously without nonce conflicts.

According to PR Newswire, QIZ Security announced the completion of a $17 million seed round financing, led by Bessemer Venture Partners and Merlin Ventures, with participation from Evolution Equity Partners, Qbeat Ventures, Singtel Innov8, Qino Cyber Capital, and others.The company positions itself as a management platform for crypto assets and post-quantum cryptography (PQC), providing continuous crypto asset discovery, risk modeling, and governance, helping large clients in finance, telecommunications, healthcare, and critical infrastructure achieve "crypto agility" to address the risk of "Q-Day," when quantum computing capable of breaking existing encryption systems may emerge as early as 2029, and collaborates with Cisco, AWS, Google, CrowdStrike, Deloitte, EY, IBM, and others to promote enterprise quantum security migration planning.

According to South Korea's Digital Asset, the comprehensive equity exchange date between Naver Financial and Upbit's parent company Dunamu has been postponed again from September 30 to December 31, marking the second delay this year, having previously been postponed from June 30 to September 30 in March.The equity exchange ratio remains unchanged, with 1 share of Dunamu exchanged for 2.5422618 shares of Naver Financial. Dunamu stated that the transaction still requires approval from the Fair Trade Commission for corporate mergers, approval for changes in major shareholders under the Credit Information Act, and reporting of changes in major shareholders under the Specific Financial Information Act, and the progress may lead to further delays or even the transaction falling through.Dunamu also pointed out that legislative discussions on the Basic Law of Digital Assets are progressing, and the content of future regulations may impact the conduct or outcome of the equity exchange.

According to the South China Morning Post, Sun Shengbin from the Wenzhou Public Security Bureau and Lou Yandi from the Zhejiang Provincial Public Security Department's Criminal Investigation Team published a technical paper on June 4 in the journal "Forensic Technology," systematically disclosing the Chinese police's forensic tools and case handling processes for virtual currency assets such as Bitcoin and Ethereum. The content covers aspects such as device cracking, evidence collection, on-chain transaction tracking, and asset freezing and seizure.The paper outlines several tracking methods, one of which involves tracking transaction fees back to exchanges like Binance, allowing the police to obtain user data. The police can acquire "Know Your Customer" (KYC) records from major exchanges such as Binance, OKX, and HTX through formal legal channels. For funds stored in exchanges, the police can freeze accounts for six months, and the freezing period can be extended.Additionally, the document emphasizes strict operational bottom lines: investigators must not privately hold private keys. The principle of "separation of case handling and custody" must be adhered to, with comprehensive supervision and the establishment of a clear regulatory chain record.

According to monitoring by Bitcoin Treasuries.NET, the shareholder vote for the merger between Adam Back's Bitcoin Standard Treasury (BSTR) and Cantor Equity Partners I has been postponed again to July 10. If the merger is completed, BSTR may purchase over 25,500 bitcoins.

According to Cointelegraph, StarkWare has released the Starknet post-quantum roadmap, stating that the roadmap is divided into three phases to address the risks of future quantum computing attacks.The first phase of the roadmap includes replacing some existing security mathematical mechanisms, specifically the Pedersen hash, with post-quantum versions and adding post-quantum signatures; the second phase focuses on migration tools that upgrade existing smart contracts without requiring developers to manually rebuild applications; the third phase involves dependencies that Starknet cannot resolve on its own, primarily relying on Ethereum's quantum upgrade roadmap.

Vitalik Buterin published an article titled "Obfuscation: building the final boss of cryptography (Part I)", systematically outlining the entire technical tree behind the mainline of the obfuscation protocol (iO). The article points out that obfuscation technology can transform programs into "encrypted programs", allowing computations on plaintext inputs while hiding internal logic. Theoretically, it can achieve "trustless trusted third parties", and when combined with blockchain, it can build nearly trustless voting systems, auction protocols, and various other applications. However, the current iO scheme, while technically polynomial time, incurs enormous practical overhead, with expected runtimes exceeding the lifespan of the universe.The article details the construction process of lattice-based iO, covering the stacking of primitives such as fully homomorphic encryption (FHE), attribute-based encryption (ABE), obfuscated circuits, function encryption, and XiO. Vitalik stated that the field has moved from "impossible" to "provably secure" over the past decade, but there remains a significant gap to practical application. He proposed three future paths: further optimizing the existing lattice-based route, adopting bolder cryptographic assumptions to simplify constructions, or exploring entirely new assumptions that are completely different from lattices, emphasizing that if any direction succeeds, it will largely "solve cryptography", enabling any protocol describable by an ideal trusted third party to be securely implemented.

Machi Brother Huang Licheng posted multiple tweets about the meme coin Machi, with the related token price once breaking through 0.0007 USD, currently reported at 0.000668 USD, with a daily increase of 235%.It is currently unclear whether the Machi Brother X account has been hacked, reminding community users to stay vigilant. The prices of meme coins are highly volatile, mainly driven by market sentiment and conceptual speculation, lacking clear practical application scenarios, and investors should be aware of the associated risks.

According to The New York Times, informed sources revealed that due to the recent significant drop in stock prices following the SpaceX IPO and the overall sluggishness of the tech stock market, OpenAI is inclined to postpone its public listing plan from later this year to 2027.It is reported that OpenAI CEO Sam Altman insists on seeking a listing valuation of up to $1 trillion and has rejected advisors' suggestions to "accept a lower valuation to expedite the listing process." Earlier, OpenAI had secretly submitted IPO application documents to the U.S. Securities and Exchange Commission (SEC) earlier this month, but did not specify a concrete timeline. Currently, OpenAI's latest valuation is $852 billion, with revenue of approximately $13 billion last year and a net loss of $21 billion.
