Google 的量子 AI 团队周二发布研究称,破解 Bitcoin (BTC) 和 Ethereum (ETH) 的密码学将需要少于 500,000 个物理量子位——比之前的估计约少 20 倍——引发了人们对量子计算机威胁区块链安全速度的最新担忧。

Google 量子研究

白皮书及随附的博客文章详细介绍了一种破解 256 位椭圆曲线密码学的方法,这是保障大多数区块链钱包和交易安全的数学系统。Google 团队估计,超导量子处理器可以在几分钟内执行攻击。

该时间表假设硬件能力与 Google 现有的一些旗舰处理器一致。

该研究并非针对静态钱包,而是模拟了实时攻击场景。量子对手可以在大约九分钟内从短暂暴露的公钥中计算出私钥。这将使攻击者有 41% 的机会击败 Bitcoin 的 10 分钟区块确认窗口。

Ethereum 在这方面面临的风险可能略小,因为其交易确认速度更快。但更广泛的影响显而易见:量子攻击的资源阈值已大幅下降。

Taproot 暴露风险

研究结果让 Bitcoin 2021 年的 Taproot 升级受到了更严厉的审视。Taproot 提高了隐私和效率,但默认开始在链上暴露公钥。它移除了旧地址格式提供的基于哈希的保护层。

这一变化将易受量子攻击影响的代币池扩大到估计 6.9 百万 BTC。该数字包括 Satoshi 时代的持仓和大量重复使用的地址——约占 Bitcoin 总供应量的三分之一。

Why this matters

If the lower quantum-resource estimates hold, they could shorten the window for Bitcoin, Ethereum and other elliptic-curve-based networks to deploy and coordinate post-quantum signature upgrades. The research also highlights that exposed public keys and reused addresses may face greater long-term risk, making migration planning a network-security and custody issue rather than a purely theoretical concern.

Google 本月早些时候将 2029 年定为内部后量子迁移截止日期。研究人员警告说,即使硬件到位,实际的迁移过程也将耗时数年。

Coin Metrics 联合创始人兼 Bitcoin 倡导者 Nic Carter 在 X 上指出了紧迫性。他强调了同一天由 Oratomic、Caltech 和 UC Berkeley 发布的另一篇论文,显示量子计算机仅需 10,000 个可重构原子量子位即可破解加密系统。

Carter 称这可能比 Google 自己的发现更令人担忧。

随着 Google 的 2029 年目标临近,交易者应监控 Taproot 采用指标、BIP-360 式升级提案的进展,以及 Bitcoin 开发人员是否承诺明确的迁移时间表。
