Zcash 开发者提议为每笔交换使用独立密钥,以使通过 NEAR Intents 的 ZEC 交易在未来量子攻击下保持私密

Zakura 团队希望通过 NEAR Intents 执行的每笔交换使用唯一密钥,以便记录在 NEAR 公链上的退款地址不能用于关联用户更广泛的支付历史。

2026 年 10 月 19 日, 与 Zcash 相关的开发者宣布了一项拟议变更,旨在保护通过 NEAR Intents 路由的 ZEC 交换免受未来量子计算机攻击的潜在威胁。

该变化由 Zakura 团队提出,拟为通过 NEAR Intents 发起的每一笔交换分配独特的加密密钥。在当前安排下,与交换相关的退款地址可能会出现在 NEAR 的公链上;Zakura 的提案旨在防止该单一已发布的退款地址在量子进展削弱现有密钥材料时,被用作关联用户更广泛 ZEC 支付历史的链路。

该提案将每笔交换的密钥生成作为修复的实质性细节。Zakura 团队表示,通过确保每笔交换使用其自身的密钥,遗留在 NEAR 公共账本上的退款地址将不会揭示不同付款之间的关联。

简要背景

NEAR Intents 是提案中提到的机制;通过该机制执行的交换可能导致退款地址被记录在 NEAR 的公链上。Zakura 团队将每笔交换密钥的方法明确表述为针对长期风险的一种防护——即未来可能能够破坏被重复使用或可关联密钥的量子计算机。

为什么这很重要

如果实施,每笔交换密钥将降低单一链上退款地址在未来被用来关联多个 ZEC 交换并重建用户支付历史的风险。若量子进展削弱了当前依赖的加密原语,这将降低事后去匿名化的可能性。该变更将是一项前瞻性的隐私工程措施,但其效果取决于 Zakura 和 NEAR Intents 相关实现的采纳与集成;这些步骤及其时间表在提案本身中并未确定。
