Ava Labs co-founder Emin Gün Sirer has raised concerns about the vulnerability of early Bitcoin holdings to quantum computing attacks, particularly those stored in Pay-to-Public-Key format. While current quantum capabilities do not pose an immediate threat, advancements like Google's Willow chip could eventually undermine Bitcoin's encryption, potentially putting trillions in cryptocurrency assets at risk. Sirer suggests freezing Satoshi's coins or setting a sunset date for P2PK transactions as possible mitigations.
Google's Quantum AI team has introduced Willow, a quantum computing chip that can solve complex problems in under five minutes, a task that would take supercomputers 10 septillion years. While Willow represents a significant advancement with its 105 qubits and improved error correction, experts believe it is still far from threatening crypto encryption, which would require a quantum computer with around 13 million qubits. This breakthrough highlights the urgent need for advancements in post-quantum cryptography to safeguard digital assets.
The Ethereum community is currently engaged in a debate over the potential increase of gas limits for blocks. While raising these limits could improve the protocol's performance, it also introduces significant security risks that must be carefully monitored.
US lawmakers are advancing a defense bill that would prohibit the Pentagon from engaging with companies supplying semiconductors and related services to Huawei Technologies Co. This bipartisan National Defense Authorization Act aims to restrict Defense Department contractors from selling critical technology to Huawei and its affiliates.
China is restricting the sale of essential components for drones, crucial to Ukraine's defense, amid rising trade tensions with the US. Manufacturers have begun limiting exports to the US and Europe, impacting the supply chain for unmanned aerial vehicles.
The U.S. defense industrial base faces significant challenges in rapidly manufacturing advanced military technologies, particularly in space, as highlighted by the Space Development Agency's struggles with supply chain disruptions. The agency plans to launch 160 satellites for its Proliferated Warfighter Space Architecture by spring 2025, but delays have arisen due to reliance on single-source components and foreign software developers, raising national security concerns. Leaders emphasize the need for a rethinking of industrial strategy to build excess capacity and address broader issues affecting military production capabilities.
US officials are now urging Americans to use encryption apps for calls and texts to protect their privacy amid a significant breach of telecoms by Chinese hackers known as Salt Typhoon. This marks a notable shift from previous government stances against strong encryption, highlighting vulnerabilities in US telecom infrastructure. Meanwhile, Russian hackers continue to exploit other hackers' infrastructure for espionage, and law enforcement has cracked down on cybercrime, sentencing members of the dark web marketplace Hydra.
Join the exclusive webinar on December 18, focusing on the integration of commercial space innovations into national security. Experts will discuss the U.S. Space Force's priorities, challenges in adopting new technologies, and strategies for startups to enter the defense market. Featured speakers include David Ariosto and Maj. Gen. Steven J. Butow.
A key House Republican has criticized the Biden administration's new export controls aimed at limiting China's chipmaking capabilities, claiming they contain loopholes that allow companies like Huawei to continue accessing American technology. Representative John Moolenaar expressed his concerns in a letter to Commerce Secretary Gina Raimondo, highlighting that certain provisions permit Chinese firms to circumvent sanctions by applying different restrictions to various parts of their operations.
