零知识区块链 Miden 计划在本月底主网上线时,同步推出原生稳定币 USDCx。该产品由 Circle 的 xReserve 基础设施提供支持,底层 USDC 将以 1:1 方式存放在 xReserve 智能合约中。

默认隐藏余额和交易记录

USDCx 的核心卖点是默认隐私。用户持有和转账时,不必在公开链上暴露余额、交易对手或完整交易历史。这一设计主要面向企业支付、机构交易和财务管理等场景。

Miden 称,用户仍可在需要时选择性证明相关信息,包括余额、资金来源和其他交易数据,以便向审计机构、监管部门或交易对手完成合规披露。

瞄准支付、交易和企业财务

按照计划,USDCx 将与 Miden 主网在同一时间上线,目标场景包括支付、交易、薪资发放以及企业资金管理。

  • 发行方式:在 Miden 链上原生发行
  • 储备结构:由 xReserve 合约持有 USDC 1:1 支持
  • 预期时间:本月底随 Miden 主网上线

公开区块链的高透明度一直是机构上链的一大障碍。交易公司通常不愿公开持仓,企业也难以将薪资和财库活动完全暴露在链上。Miden 希望用默认隐私的方式,降低这类场景使用公链的阻力。

Miden押注“PriFi”方向

Miden 是一家位于加州的零知识区块链项目,采用客户端侧证明架构,即交易在用户设备上执行并生成证明,而不是把完整过程暴露给网络。

该公司把 USDCx 视为更大范围“PriFi”方向的基础设施,覆盖私密机构交易、企业间支付、跨境支付、薪资和企业财库管理等用途。

补充信息:Miden 于 2025 年 4 月从 Polygon 分拆为独立项目,背后投资方包括 a16z crypto、1kx 和 Hack VC 等。
