first_img A U.S. judge ruled that the Trump administration illegally retaliated against Anthropic, lifting the ban and issuing a permanent injunction

U.S. Federal Judge Rita Lin issued a partial summary judgment in a 59-page ruling regarding Anthropic's lawsuit against the Trump administration, determining that the government's punishment of Anthropic for publicly refusing to allow the military to use its Claude large model for mass surveillance of U.S. citizens and lethal autonomous operations constituted illegal retaliation, violating the First Amendment, due process clause, and the Administrative Procedure Act. The judge also revoked the related designations and Defense Secretary Hegseth's injunction, issuing a permanent injunction.The controversy arose from the Pentagon's demand that Anthropic remove all usage restrictions and accept terms allowing "all lawful uses," while Anthropic maintained its last two bottom lines. On February 27, 2025, Trump ordered all federal agencies to cease using the company's technology, and Hegseth subsequently prohibited any military contractors from doing business with it. During this process, the government abandoned its core claims, acknowledging that Anthropic had no backdoor access to the deployed models and that the risks of Claude were no greater than those of other "black box" systems. Lin pointed out that the government's punishment under the guise of "national security" was not a blank check, and that the government had been operating under the preliminary injunction since March without indicating any harm.Anthropic did not achieve a complete victory, as its claim that Trump's directive exceeded presidential authority was dismissed. Anthropic informed the court that if the relevant measures continued, its defense-related revenue would decrease by 50% to 100%, resulting in a loss of billions of dollars in overall revenue by 2026.

RQD Clearing, a U.S. clearing and custody institution, has completed a $74 million financing round, led by Bain Capital

According to CoinDesk, the U.S. clearing and custody institution RQD Clearing announced the completion of a $74 million financing round, led by Bain Capital Tech Opportunities, a technology investment division of Bain Capital, with participation from ABN AMRO Clearing Bank and Nyca Partners. This round of financing will be used to expand operations in North America, Asia, and the Middle East, and to enhance infrastructure development for digital asset custody and asset tokenization.RQD primarily provides post-trade clearing and custody services for broker-dealers, investment advisors, and overseas financial institutions in the U.S. market, responsible for key processes such as securities and funds settlement, and risk management. This year, the company has processed approximately 515 million stock trades, involving nearly $2 trillion, accounting for about 2.4% of the National Market System (NMS) stock trading volume in the U.S.As Wall Street institutions accelerate their exploration of on-chain finance, traditional market infrastructure is becoming an important direction for the competition of tokenized assets. RQD has previously collaborated with Blue Ocean Technologies to advance the clearing and settlement infrastructure for tokenized U.S. stocks and has aligned with the tokenized securities framework of the Depository Trust & Clearing Corporation (DTCC).

first_img Ethereum developers propose upgrading the staking contract to defend against quantum attacks

According to CoinDesk, Ethereum researchers have proposed rebuilding the validator deposit contract to support a new cryptographic system and ultimately stop accepting deposits protected by the existing BLS signatures. This proposal targets the deposit contract, aiming to add a switch that prevents the network from accepting the currently relied-upon signature format.Currently, the contract only accepts BLS keys because their exact size is hardcoded, while the new draft allows for different key sizes, with each deposit tagged by the cryptographic system used, where BLS receives a tag of zero, reserving space for future schemes.If the proposal is approved, it will initially operate with BLS deposits, while other schemes can be registered simultaneously. Future decisions may permanently disable new BLS deposits, at which point validators who have staked using BLS keys will not disappear, but new validators will not be able to join using this method. Ethereum will ultimately need to change separately to inform validators how to check new signatures. This is part of the migration for validators, while another part is already in progress—EIP-8141 framework transaction proposals will allow regular Ethereum accounts to change the cryptographic method for approving transactions without changing their address.The urgency stems from research released in March by Google's Quantum AI research department, which outlined five quantum attack paths against Ethereum, putting over $100 billion in assets at potential risk. The Ethereum Foundation is advancing core protocol changes with a target around 2029. Currently, the amount of ETH staked in Ethereum is approximately 42.4 million, valued at about $10.4 billion.
