DogPay announced a strategic partnership with DeCard to jointly launch the DogPay physical payment card, aimed at further bridging stablecoin assets with the global traditional payment network.It is reported that this payment card combines DeCard's regulated card issuance and settlement infrastructure with DogPay's modular digital financial platform. Eligible users can transact at over 150 million Visa-supported merchants worldwide, supporting real-world application scenarios such as offline POS machine consumption, retail shopping, and ATM withdrawals, thereby directly converting stablecoin balances into everyday purchasing power.DogPay officials stated that the launch of the physical payment card aims to meet the growing market demand for compliant and globally accepted digital asset payment tools, further promoting the deep integration of digital assets with regulated financial infrastructure.

According to Decrypt, Admiral Samuel Paparo, the commander of the U.S. Pacific Command, stated during a hearing before the U.S. House Armed Services Committee that the U.S. government is currently running a Bitcoin node for cybersecurity-related testing, but is not engaged in mining.Paparo indicated that the U.S. military's interest in Bitcoin primarily focuses on its value as a computer science tool, including cryptography, blockchain, and reusable proof-of-work mechanisms, with the aim of using the Bitcoin protocol to strengthen cybersecurity and enhance military capabilities, which is still in the experimental stage. He also mentioned that maintaining the global dominance of the U.S. dollar aligns with U.S. military interests and gave a positive evaluation of the stablecoin legalization bill, the GENIUS Act, signed by Trump last summer, believing that the bill helps to solidify the global position of the dollar.

Binance founder CZ stated on social media, "The autobiography 'Freedom of Money' has been launched in some countries. It seems that the book will be available for global purchase at midnight on April 8 (local time). All proceeds from the book will be donated to charity."

Former Google quantum hardware chief and 2025 Nobel Prize in Physics winner John Martinis warned that Bitcoin could become one of the first real targets for quantum computing attacks. He stated that recent research from Google shows that advanced quantum computers could derive Bitcoin private keys in a matter of minutes, significantly lowering the computational security barriers that the network currently relies on.Since Bitcoin relies on elliptic curve cryptography and the network upgrades slowly and is decentralized, this makes the quantum threat harder to address than in traditional financial systems. The public key exposure window when broadcasting Bitcoin transactions could be exploited by quantum computers to intercept funds before the transaction is finally confirmed. John Martinis emphasized that while building such quantum computers remains an extremely challenging engineering task, the community should not be complacent and should plan for quantum-resistant upgrades as soon as possible, anticipating that related threats will gradually emerge within 5 to 10 years.

According to the official blog, Circle's institutional-grade blockchain Arc has released a phased upgrade roadmap for post-quantum cryptography (PQ), planning to introduce post-quantum signature schemes at the launch of the mainnet, gradually covering full-stack layers such as private state protection, infrastructure hardening, and validator authentication.The Arc mainnet will support post-quantum signatures from the outset, using an opt-in mechanism that does not require mandatory migration or a full network reset, allowing users to independently create wallets with long-term security. The recent goal is to extend quantum resistance to the private virtual machine (VM) layer, protecting private balances, private transactions, and private payees, with public keys additionally encapsulated in a symmetric encryption layer under privacy mode.The mid-term plan is to advance the upgrade of the infrastructure layer, aligning with industry standards such as TLS 1.3, covering access control, cloud environments, and hardware security modules (HSM). The long-term goal is to complete the hardening of validator signatures. Given that Arc's block finalization time is less than 1 second, the current assessment considers the risk of quantum attacks in this phase to be relatively limited, and it will be steadily advanced after the post-quantum consensus toolchain matures.Circle also warns that attackers may adopt a "collect now, decrypt later" strategy, and institutions should plan their cryptographic migration paths as early as possible.

According to BBX data, yesterday, as the last day of the first quarter, multiple companies executed the quarter-end "automatic treasury conversion" and hard asset settlement. The core data is as follows:$120 million swept in at quarter-end: Block Inc. (NYSE: $XYZ) strictly implemented its algorithm-driven treasury strategy yesterday, automatically sweeping approximately $120 million of idle fiat profits into its Bitcoin pool at the end of the first quarter. This "no human intervention" investment mechanism ensures it is insulated from emotional disturbances caused by short-term price fluctuations."Physical isolation" of computing power: Riot Platforms (NASDAQ: $RIOT) announced yesterday that the first batch of 2 EH/s computing power from its new factory on Corsica has successfully connected to the grid. Notably, this portion of computing power is designated as a "treasury dedicated line," with all BTC produced being physically cold-stored, 100% retained, completely independent of the funds pool used for daily operational sales.150 mining machines settled in cryptocurrency: Canaan Inc. (NASDAQ: $CAN) disclosed its financial update for the first quarter yesterday, confirming that it has settled part of the sales balance for mining machines from major clients directly in Bitcoin, totaling 150 BTC, officially closing the loop from "selling shovels" to "hoarding gold."$40 million regional hedge: MercadoLibre (NASDAQ: $MELI) disclosed yesterday in its quarter-end asset revaluation that it added a mixed position of $40 million in BTC/ETH in late March. This move aims to hedge against the sharp depreciation of several Latin American currencies against the US dollar in the first quarter.$85 million staking snowball: DeFi Technologies (CBOE: $DEFTF) announced yesterday that its treasury size has surpassed $85 million. In addition to asset appreciation, the SOL it holds has generated staking interest in the first quarter, which has all been reinvested, achieving absolute quantity compound growth of its crypto assets.

According to Cointelegraph, Google has set 2029 as the deadline for its post-quantum cryptography migration, warning that the threat of quantum computing may arrive sooner than expected.Google stated that the rapid advancements in quantum computing hardware and quantum error correction, along with updates to the timeline for quantum computers to break current encryption standards, have heightened the urgency for action. This is the first time Google has set a timeline for the deployment of post-quantum capabilities in its products, ahead of some industry predictions for "Q-Day." Google is developing its quantum chip Willow, which has 105 qubits and is one of the most powerful quantum processors currently available.

According to official documents, Morgan Stanley has submitted an S-1/A amendment for its Bitcoin spot ETF "Morgan Stanley Bitcoin Trust" (MSBT).
