Blockstream 研究人员 Mikhail Kudinov 和 Jonas Nick 在 12 月 5 日发布的修订论文中提出，基于哈希的签名技术可能是保护比特币免受量子计算机威胁的关键解决方案。研究人员认为，基于哈希的签名是一个令人信服的后量子解决方案，因为其安全性完全依赖于与比特币设计中已有的哈希函数假设相似的机制。该方案已在美国国家标准与技术研究院（NIST）的后量子标准化过程中经过广泛的密码分析，增强了其稳健性的可信度。据估计，创建于 2012 年之前的较旧的 Pay-To-Public-Key Bitcoin 钱包（包括中本聪价值 980 亿美元的持有量）包含约 6000 亿美元的 BTC，这些钱包将首先面临量子计算机的威胁。（DL News）

According to BlockBeats, U.S. Senate Banking Committee Chairman Tim Scott announced significant progress in advancing a comprehensive cryptocurrency bill into law following a meeting with top banking CEOs. On Thursday, Scott met with Brian Moynihan of Bank of America, Jane Fraser of Citigroup, and Charlie Scharf of Wells Fargo to discuss this landmark legislation. The proposed bill aims to establish regulatory guidelines for the digital asset industry and empower agencies like the SEC and CFTC. This week, the three banking CEOs are expected to meet with senators to further discuss the cryptocurrency legislative proposal. The meetings are reportedly held separately with Democrats and Republicans, both described as "cordial." Insiders revealed that discussions covered topics such as yields, decentralized finance, and anti-money laundering measures. The banking association has identified gaps in the GENIUS Act, which became law this summer. They argue that the law inadequately restricts stablecoin issuers from paying interest to holders, potentially making these assets more attractive as value storage and credit mechanisms rather than just payment tools, thus creating "market-distorting incentives" for the banking sector. Additionally, banking groups believe that the restrictions imposed by the GENIUS Act can be easily circumvented by exchanges, brokers, and other related parties.

According to PANews, Glassnode recently analyzed on the X platform that the unrealized losses across the cryptocurrency ecosystem have surged to approximately $350 billion. Of this, Bitcoin alone accounts for about $85 billion in unrealized losses. As several on-chain indicators suggest a contraction in overall liquidity, the market is likely to experience high volatility in the coming weeks.

According to PANews, Blockstream researchers Mikhail Kudinov and Jonas Nick have examined various methods to upgrade the Bitcoin blockchain for quantum resistance in a revised paper published on December 5. They propose hash-based signatures as an attractive post-quantum solution due to their security relying solely on hash function assumptions, similar to Bitcoin's foundational design. Kudinov shared his findings with the Bitcoin developer mailing list, noting that these schemes have undergone extensive cryptanalysis during the National Institute of Standards and Technology's (NIST) post-quantum standardization process, boosting confidence in their robustness. Hash-based signatures depend on hash functions, which are considered quantum-resistant mathematical algorithms. Unlike Bitcoin's public key encryption, quantum algorithms struggle to break hash functions. By simply increasing the output size, hash functions can counteract brute-force searches by quantum computers, ensuring the security of applications like digital signatures. However, the implementation of hash-based signatures remains under discussion. Decisions are needed on issues such as maintaining low verification costs, standardizing various hash-based signature implementations, and whether the entire network's historical record is necessary for transaction verification.

为什么同样的策略，Strategy做是神话，别人做就是笑话？在 AI 叙事如货运列车般碾压一切的当下，比特币还是那个最好的资产避风港吗？
