BTC 比特币抗量子保护成本骤降：代码优化与AI加速的突破
在短短几天内，抵御量子计算对比特币威胁的保护成本急剧下降。由 StarkWare、Yukon Research 和 Eigen Labs 联合发起的一项公开竞赛，促使开发者和人工智能代理大幅加快了必要计算的进程。在一周时间内，基于 GPU 算力的估算成本从约 320 美元降至 67 美元。这一显著降幅充分展示了代码优化如何降低资源需求，从而构建出更能抵御量子威胁的交易机制。
核心摘要
- 抗量子比特币交易的估算成本从 320 美元降至 67 美元。
- 通过代码优化，一项公开竞赛极大地加速了必要的计算过程。
- 人工智能模型在 GPU 基准测试中取得了最佳成绩。
- 该方案仍存在局限性，尚未构成对量子威胁的全面防护。
一周内“GPU账单”减半：量子安全比特币优化挑战
“量子安全比特币优化挑战”旨在降低创建抗量子交易的成本。StarkWare、Yukon Research 和 Eigen Labs 发起了这项竞赛，以衡量外部求解器的进展。目前仪表盘显示的 GPU 算力估算成本约为 67 美元，而一周前这一数字还在 320 美元左右。
上个月，第一笔抗量子交易在主网上被挖掘。StarkWare 开发的这项技术旨在不要求网络分叉的情况下保护比特币。其初始构建需要约 3,100 个 GPU 计算小时，成本为 320 美元。自竞赛启动以来，这一负载已大幅降低。
成本的下降主要源于计算优化。最耗时的过程是在向区块链注册数据之前进行的穷举搜索。该机制在网络预期签名的位置插入哈希值。由于有效输出大约出现在每 70 万亿种组合中的一种，因此必须对输入进行哈希处理，直到找到期望的结果。
AI 代理加速计算进程
求解器在用于衡量其性能的标准参考上取得了快速进步。在标准的 RTX 4090 显卡上，基准测试速度从每秒验证 1.46 亿个候选项提升至超过 8.2 亿个。总共观察到了 62 项改进。这些结果直接减少了所需的 GPU 计算小时数。
使用 AI 模型的开发者 notably 取得了最佳记录。StarkWare 指出，Anthropic 的 Opus 5 和 Fable 5.1 位居排行榜前列。OpenAI 的 GPT-6 Astra、Grok 4.6 以及 Kimi 紧随其后。这场竞赛展示了 AI 在计算优化中日益增长的作用。
However, technical problems remain, so the $67 figure needs to be interpreted with caution. StarkWare made it clear that the figure is an estimate based on specific hardware assumptions and not market prices. This amount can change every time a solver breaks the record. Therefore, this decline reflects the state of competition rather than fixed rates.
Protection remains limited in the face of "Q-Day"
This breakthrough does not mean that Bitcoin is unbreakable to quantum computing. The transactions involved are still non-standard transactions and must be sent directly to miners. In addition, the device only protects bitcoins whose public keys have not yet been made public. StarkWare believes that software forking is the long-term solution.
These limitations become particularly important as the Q-Day approaches. "Q-Day" refers to the hypothetical moment when a quantum computer may crack wallet encryption. The potential exposure risks of the Internet in the face of this development have attracted more attention. Coinbase is already working on developing a hosting strategy for the post-quantum era.
Currently, the competition focuses mainly on measuring progress in computing costs. The drop from $320 to $67 shows the effectiveness of developers and AI model optimization. However, this solution only solves part of the anti-quantum correlation problem. Future records may change estimates again. This evolution concerns Bitcoin and its users.
To sum up, Bitcoin's protection against quantum computing has made progress at the computing level, but its limitations are also clearly visible. Although estimated costs have dropped significantly, this approach has not yet constituted comprehensive network protection. Costs may continue to evolve as solver performance continues to improve, but will not change the fundamental constraints highlighted by StarkWare.
