According to CoinDesk, the U.S. Department of Commerce has allocated up to $100 million each to three quantum computing companies: Rigetti, D-Wave, and Quantinuum, totaling up to $300 million, to expand hardware, manufacturing, and error correction systems, while simultaneously acquiring minority stakes in the three companies.Meanwhile, Bitcoin and Ethereum developers are accelerating the advancement of post-quantum cryptography upgrade plans. The Ethereum Foundation has set December 2029 as the deadline for the base layer quantum resistance upgrade, covering the execution layer, consensus layer, and data layer; although there is no unified timeline for Bitcoin, proposals BIP-360 (post-quantum output types) and BIP-361 (phasing out ECDSA and Schnorr signatures) have been accelerated, with researchers also viewing 2029 as a critical window for completing a trustworthy migration path.

The Ethereum Foundation stated on the X platform that the Trezor hardware wallet now supports the "Clear Signing" feature through the ERC-7730 standard, making transactions more readable and understandable on the hardware device.This progress is the result of the Clear Signing working group promoted under the foundation's "Trillion Dollar Security Initiative," aimed at reducing the risk of users suffering asset losses due to "blind signing" of unclear transactions and encouraging more wallets and decentralized applications to participate.

The SEMICON Taiwan 2026 Memory Summit took place on the 1st, where Nikhil Cherian, Senior Director of Supply Chain Infrastructure at Google Cloud under Alphabet, pointed out that with the popularity of multimodal and mixed expert architectures, AI computation has shifted from being power-limited to memory-limited, with high-performance memory accounting for over 75% of the cost of AI server hardware bill of materials. In the face of capacity, bandwidth, and power consumption bottlenecks, Google is breaking through the AI memory bottleneck through a dual-track strategy of hardware offloading for inference and training, and lossless quantization software algorithms.Google adopts an offloading strategy in hardware architecture, launching TPU 8i for low-latency inference and TPU 8t specialized for large-scale training. The TPU 8i is equipped with 288 GB of high-bandwidth memory, with SRAM capacity on the chip increased threefold to 384 MiB, placing dynamic conversation states and key-value caches on the chip itself to achieve zero chip-off latency. The TPU 8t forms a super-large computing cluster with 9600 chips, achieving a shared pool of HBM at a scale of 2 PB, eliminating chip-off data transfer bottlenecks, along with TPU Direct Storage technology.Google has developed the training-free TurboQuant lossless quantization algorithm, compressing the key-value cache of large models from 32 bits to 3 bits, reducing memory usage by six times without loss of accuracy, resulting in an eightfold acceleration in attention computation, and integrating old-generation DRAM technology to extend the lifecycle of components.

According to TechCrunch, OpenAI is fighting back against Apple's lawsuit regarding the leak of trade secrets, stating that Apple itself has vulnerabilities in its information security management and employee departure processes, and cannot prove that the relevant information is protected trade secrets.Apple previously accused OpenAI of obtaining hardware-related secrets through former employees who left Apple and requested the court to expedite the evidence investigation. In the latest legal documents submitted, OpenAI stated that Apple allows employees to use personal iCloud accounts to handle work materials and did not promptly revoke access after employees left. OpenAI claimed that Apple did not specify the exact trade secrets that were allegedly stolen, but only referred generally to information such as product development processes, supply chains, and testing.OpenAI believes that Apple's lawsuit is more about restricting its development in the AI hardware field and denies that the company needs or uses Apple's trade secrets. The focus of the dispute between the two parties centers on employee mobility, intellectual property protection, and competition in the AI hardware sector.

According to Decrypt, Ledger's Chief Technology Officer Charles Guillemet stated that the Coldcard vulnerability incident exposed weaknesses in hardware wallet random number generation and emphasized that AI is reshaping the cybersecurity offensive and defensive landscape. Guillemet pointed out that the security model of hardware wallets "lives or dies by random numbers," and this incident proved that in the most expensive way.Ledger stated that its hardware wallets were unaffected because their mnemonic phrases are generated by a hardware random number generator within a certified secure element, with no software fallback path, generating a complete 256-bit random number each time. Guillemet believes that open-source code, if not thoroughly reviewed, does not equate to security, and AI is enabling attackers to scan code and identify vulnerabilities at machine speed, requiring defenses to advance at the same speed, which relies on secure design, hardware, and mathematics. Guillemet suggested that users should understand how the random number generation of a hardware wallet works and whether it has been independently certified when choosing one.

The Coldcard hardware wallet attack has expanded to approximately $116 million, with attackers transferring 1,816 BTC from over 5,200 addresses. Galaxy Research confirmed that a fourth wave of transfers has occurred, with this wave alone transferring about 449 BTC after adjustments.Alex Thorn, head of Galaxy Research, stated that the latest activity may be "the fourth round of organized theft," with a transfer rate reaching 13.8 transactions per block, which is about 45 times the baseline level before the incident. Their analysis suggests that the related patterns indicate multiple groups may be scanning the affected key space in parallel. The root of the incident can be traced back to a 2021 firmware update for some Coldcard devices, which changed the wallet seed generation process from a hardware random source to a predictable software model. The Canadian manufacturer Coinkite recommends that users who generated wallet seeds on Coldcard devices transfer their funds to a new secure wallet as soon as possible.

Zhao Changpeng posted on platform X, stating that regarding the suspected vulnerability of the Coldcard wallet that led to over $38 million in Bitcoin being stolen, even hardware wallets may have vulnerabilities.Even long-established wallets may have vulnerabilities. To reduce risk, one might consider diversifying funds across several wallets, but this brings another set of risks. Nothing is 100% secure.

Canadian hardware wallet manufacturer Coinkite has issued a security warning, advising users who generated mnemonic phrases with Coldcard Mk3 firmware versions 4.1 to 5.3 to migrate their assets as soon as possible. The company stated that preliminary analysis shows wallets using BIP-39 passphrases are at lower risk, and Mk4, Q, and Mk5 devices are not affected; the investigation is still ongoing.Meanwhile, security researchers are investigating an anomalous transfer event involving 594.48 BTC (approximately 38.3 million USD). AnchorWatch CEO Rob Hamilton stated that attackers transferred 1,324 UTXOs through 500 transactions within three blocks and speculated that the issue may stem from insufficient random number entropy during the wallet generation process. Wizardsardine CEO Kevin Loaec believes the vulnerability may be related to a specific software library, secure chip, or a particular batch of devices, as well as low-entropy random number generators in firmware versions, with attackers possibly using AI-generated scripts to brute-force the affected wallets. There is currently no conclusive evidence linking this fund transfer to a direct vulnerability in Coldcard Mk3.

According to The Block, Trezor's Chief Business Officer Danny Sanders refuted recent criticisms of cryptocurrency hardware wallets made by blockchain investigator ZachXBT.Earlier this week, ZachXBT posted on Telegram, "All hardware wallets are complete garbage and I do not recommend using them for important tasks such as signing transactions or storing funds," and suggested that users use a dedicated iPhone to store funds and sign transactions.In response, Sanders acknowledged in an interview that firmware/software updates for hardware wallets can sometimes interfere with urgent or large transactions, and that the user experience can indeed be "clunky," understanding the users' frustration. However, he opposed ZachXBT's blanket statement: while hardware wallets may not be the best single solution for advanced users managing large amounts of funds, they are not garbage.He pointed out that compared to hardware wallets, the operating system and connectivity features of an iPhone present more "attack risks." For the average cryptocurrency user, hardware wallets remain the best self-custody option available.

Ledger researchers found that all Tangem hardware wallet cards' passwords can be reset through a laser attack.This attack requires physical contact with the device and approximately $250,000 worth of laboratory equipment, and the cards that are already in circulation cannot be patched to fix this issue.

According to The Block, the Donjon security team under Ledger has bypassed the firmware verification mechanism of the TROPIC01 chip used in the Trezor Safe 7 through precise laser attacks in a laboratory environment, allowing unauthorized firmware to be loaded as long as the attacker possesses the physical device.Chip manufacturer Tropic Square further discovered that there are additional attack vectors in the MAC-and-Destroy security mechanism used for PIN verification on this chip, but details will not be disclosed until the enhanced version of the chip is launched at the end of 2026.Trezor stated that the PIN, mnemonic backup, and private keys have never been stored on a single chip, and they have notified partners, so ordinary users do not need to take action. Currently, the feasibility of attacks can be reduced by disabling the chip's MAINTENANCE mode.

According to Decrypt, the cryptocurrency technology company Quantography Labs has announced the launch of the early access version of the cryptocurrency wallet Lock.com. This product uses "Isolated Signing" and an Air-Gapped architecture, enabling offline private key management without the need for dedicated hardware wallet devices.The official statement indicates that Lock.com separates the signing environment from the network broadcasting environment: private keys are always stored in a completely offline device, while transactions are created and broadcast on a connected device, thus avoiding private key exposure to the internet. The platform emphasizes that users can directly use existing devices without relying on third-party hardware manufacturers or supply chains. Additionally, Lock.com integrates post-quantum cryptography architecture, including ML-DSA digital signatures and ML-KEM key encapsulation mechanisms, to enhance security in future quantum computing environments.Quantography Labs stated that the current early access phase is mainly used to collect user feedback and prepare for a subsequent full launch.
