threats

Coinbase CEO Brian Armstrong stated that he will personally invest in research on Bitcoin's resistance to quantum-related issues and emphasized that the industry needs to push for solutions as soon as possible.Coinbase Chief Security Officer Philip Martin previously pointed out that as research in quantum computing progresses, the industry needs to accelerate its response to potential threats. He stated that post-quantum cryptography is feasible but still in the early stages of development. If implemented hastily, it could introduce new security risks, and there needs to be a consensus on issues such as how to handle wallets that have not completed migration. In addition, Coinbase has initiated related infrastructure upgrades and research, and is promoting collaboration among developers and the community to advance quantum-resistant solutions.

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 a report by Cointelegraph, Ark Invest and Unchained jointly released a report stating that although most of the Bitcoin supply is secure against breakthroughs in quantum computing, approximately 34.6% of Bitcoin still faces potential risks.The threatened amounts include about 5 million BTC (25% of the total supply) that are transferable due to address reuse, around 1.7 million BTC (8.6%) stored in early P2PK addresses, and about 200,000 BTC (approximately 1%) affected by the P2TR address type.If quantum computers can break Bitcoin's elliptic curve cryptography (ECC), these funds may face the risk of theft, but this stage is expected to take years to achieve. Ark Invest believes that this is a "long-term risk," and therefore the Bitcoin community has ample time to research and implement quantum protection measures.

The crypto KOL @sillytuna revealed on social media that his personal address has encountered a serious security incident, resulting in a loss of approximately 24 million AUSD. He stated that the incident involved violence, weapons, and kidnapping threats, and the police have intervened. @sillytuna mentioned that he will completely withdraw from the crypto space and is "grateful to have kept his limbs."According to previous news from ChainCatcher, monitoring by Shield indicates that the address associated with crypto KOL @sillytuna (0xd2e8...ca41) has suffered from an address poisoning attack, resulting in a loss of approximately 24 million aEth USDC.

StarkWare CEO Eli Ben-Sasson spoke on X about the potential impact of quantum computing on the crypto industry, calling for a proactive deployment of post-quantum security upgrades across multi-chain ecosystems, including Bitcoin, and proposed a five-step action plan:Acknowledge the threat and clearly recognize that once quantum computers mature, they will pose a severe challenge to the existing public key cryptography system, and take decisive action to implement countermeasures.Enhance education and information dissemination, systematically learn about the current state of quantum computing development and feasible solutions in post-quantum cryptography (PQC), and spread relevant knowledge within the community to raise overall awareness.Organize and invest resources to support and collaborate with post-quantum cryptography experts, promote multiple research and engineering practices, and provide funding and community initiative support for related projects.Listen to expert advice and establish standards, with experts proposing specific technical routes, including the selection of new signature algorithm standards and the reasonable post-quantum security levels required for hash functions.Promote protocol and infrastructure upgrades, introduce new quantum-resistant signature mechanisms at the core protocol layer, and ensure compatibility and integration with key infrastructures such as wallets to ensure a smooth transition.

Star investor Kevin O'Leary from "Shark Tank" posted on the X platform that he remains bullish on Bitcoin, but now quantum computing has become a new concern. He stated that quantum computing is causing institutions to hesitate, as they worry that one day quantum computers might crack the blockchain.As long as this issue remains unresolved, institutional investors are unlikely to increase their allocation to Bitcoin above 3%. They will remain cautious and disciplined, waiting for clearer conclusions.

According to Cointelegraph, venture capitalist Nic Carter stated in a podcast that the long-term inaction of Bitcoin developers regarding the potential threat of quantum computing to Bitcoin may lead to dissatisfaction among large institutions holding significant amounts of Bitcoin (such as BlackRock), ultimately triggering an "institutional takeover."Nic Carter warned that institutions will not tolerate the core security issues of Bitcoin being ignored for an extended period. "If developers continue to be inactive, institutions will lose patience and will fire the current developers, replacing them with new ones."

According to relevant page information, Bitcoin Improvement Proposal 360 (BIP-360) has been added to the official code repository.This proposal introduces the Pay-to-Merkle-Root (P2MR) output type, aimed at enhancing Bitcoin's defense against quantum computing threats through a soft fork.

According to market news, Strategy's Executive Chairman Michael Saylor announced during the earnings call that a Bitcoin security initiative is planned to address quantum computing and other future security threats. This initiative will collaborate with global cybersecurity, cryptographic security, and Bitcoin security councils to coordinate relevant research and risk responses.Saylor stated that the current consensus is that quantum threats are not expected to materialize for at least another 10 years or longer, and many global teams are already developing quantum-resistant protocols. He emphasized that Bitcoin is scalable, and if a quantum upgrade is needed in the future, its network will become more resilient as a result. He also reminded that it is crucial to seize the opportunity to address such risks; acting too early may lead to immature technology, while acting too late could result in unnecessary risks.

In response to a recently circulated so-called "lawyer's letter," Binance stated that the document was not issued by Binance and is a forged document. Previously, X user Lewsiphur accused Binance of being insolvent and claimed that it would have a more severe impact on the market than FTX. Subsequently, he shared a suspected cease-and-desist letter allegedly issued by Binance, stating that failure to delete the relevant content within the specified time would result in legal action.The official Binance customer service account responded, stating: "This letter did not come from Binance, but is a forged document with strong subjective speculation. We remind users to be vigilant against false documents and misleading information." As of now, the aforementioned related accusations have not been deleted.Regarding the recent bankruptcy rumors surrounding Binance, the company has repeatedly denied them and stated that such claims lack factual basis. Binance co-founder He Yi also mentioned that the concentrated withdrawal behavior initiated in the community can be seen as a stress test to some extent, and on-chain data shows that the related activities have not led to a decrease in the platform's asset scale.

According to official news, Coinbase has announced the establishment of an independent advisory committee on quantum computing and blockchain to address future quantum threats. The committee brings together world-renowned experts with the goal of assessing the impact of quantum computing on the blockchain ecosystem and providing clear, independent guidance to the broader community. The committee will publish position papers on quantum risks, offering defense recommendations for developers and institutions, and providing real-time analysis on technological breakthroughs.Coinbase stated that this committee is part of its post-quantum security roadmap, which also includes updating the handling of Bitcoin addresses, internal key management systems, and advancing support for post-quantum signature schemes like ML-DSA in multi-party computation (MPC) systems. The committee is expected to release its first position paper on quantum risk assessment and resilience building roadmap early next year.Committee members include Scott Aaronson, Director of the Quantum Information Center at the University of Texas at Austin, Dan Boneh, Co-Director of the Blockchain Research Center at Stanford University, Justin Drake, Researcher at the Ethereum Foundation, Sreeram Kannan, Founder of EigenLayer, Yehuda Lindell, Chief Cryptographer at Coinbase, and Dahlia Malkhi, an expert in distributed systems at the University of California, Santa Barbara (UCSB).

According to Jin Ten, investor sentiment fluctuated on Tuesday, with the U.S. stock market closing with the largest single-day drop in three months. Jamie Cox, managing partner of Harris Financial Group, stated that there are no signs of investors fleeing. He believes that the Greenland issue and tariff threats are unlikely to lead to a market correction, and he would be surprised if the stock market drops 3% to 5% this week.

According to CoinDesk, geopolitical tensions have risen due to Trump's tariff threats against European countries opposing his "takeover of Greenland," leading to a simultaneous decline in Bitcoin and major cryptocurrencies along with Nasdaq futures.In addition to macroeconomic headwinds, internal market mechanisms may also exacerbate price volatility. Data shows that Bitcoin options market makers are currently in a negative gamma exposure in the $86,000–$95,000 range. In a negative gamma state, market makers often passively buy when prices rise and sell when they fall to hedge risks, thereby amplifying market fluctuations. The market is also watching the potential Supreme Court ruling risks regarding Trump's tariff policies. Analysts point out that if the ruling is unfavorable, it could trigger greater volatility in trade policies, fiscal deficit expectations, and other areas in the short term.In traditional markets, the yield on the U.S. 10-year Treasury bond has risen to a four-month high of 4.37%, the dollar has weakened, and U.S. stock futures are under pressure, indicating overall pressure on U.S. stocks and risk assets.

GrayScale's report states that the cryptocurrency market will enter an adjustment phase in the fourth quarter of 2025, with all six major crypto sectors showing negative returns. Privacy-related assets performed better than other sectors, especially Zcash (ZEC). As the integration of blockchain and traditional finance deepens, the demand for privacy tools becomes increasingly evident. The usage rate of Zcash's "shielded accounts" continues to grow, indicating a rising market demand for privacy features.Other notable privacy assets include Monero (XMR), Decred (DCR), Dash (DASH), Basic Attention Token (BAT), and Beldex (BDX). Among them, Dash's daily trading volume doubled in Q4, BAT's Brave browser reached over 100 million monthly active users, and Beldex integrated LayerZero to achieve cross-chain interoperability. Looking ahead to 2026, the market is focused on two major themes: first, the U.S. Congress's legislation on the structure of the cryptocurrency market, which is expected to become law and provide traditional financial rules for the crypto capital market; second, the potential threat of quantum computing to blockchain encryption methods. Although quantum computing technology is still in its early stages, it may prompt the market to assess the ability of blockchain to respond to quantum challenges.

According to DL News, Blockstream researchers Mikhail Kudinov and Jonas Nick proposed in a revised paper published on December 5 that hash-based signature technology could be a key solution to protect the $1.8 trillion Bitcoin blockchain from the threat of quantum computers.The researchers believe that hash-based signatures are a compelling post-quantum solution because their security relies entirely on mechanisms similar to the hash function assumptions already present in Bitcoin's design. This scheme has undergone extensive cryptanalysis during the post-quantum standardization process at the National Institute of Standards and Technology (NIST), enhancing the credibility of its robustness.It is estimated that older Pay-To-Public-Key Bitcoin wallets created before 2012 (including Satoshi Nakamoto's holdings worth $98 billion) contain about $600 billion in Bitcoin, and these wallets will be the first to face the threat of quantum computers.

On-chain analyst Willy Woo tweeted that the future "quantum computing era" may allow public keys to be reverse-engineered into private keys, leading to asset risks. Currently, Taproot addresses starting with "bc1p" are not quantum-safe, while SegWit addresses starting with "bc1q" still have protective capabilities. He advises users to transfer BTC to SegWit or legacy format addresses and to avoid spending until an upgrade to quantum-safe protocols is completed to prevent exposure of public keys.Woo expects that the Bitcoin network will complete its quantum-safe upgrade in about 7 years, while quantum threats may emerge as early as after 2030.
