加密内存池与永续期货资金费率操纵
文章 arXiv papers · 作者: Benjamin Marsh
总结
本文考察加密的提交后揭示交易系统如何使永续期货资金费率信号暴露于自行发起的状态操纵。攻击者若了解自己的交易,并持有受状态变化影响的权益,就可能通过操纵资金费率计算的输入获益。由于资金转移同时取决于费率信号和接收方持仓量,即便加密处理本身很快,延迟披露也可能影响经济结果。
所提分析将纠偏建模为套利:交易者根据价格冲击和库存成本决定交易规模。文章认为,交易排序屏障会阻止普通自适应搜索者在已提交阶段作出响应,因此纠偏可能慢于揭示后所能达到的速度。论文还指出,可预测资金费率在价格中的资本化程度降低,是另一个放大渠道;并提出一项局部安全指数,用于区分攻击者信息盲区、纠偏保护和价格资本化保护。所提供文本给出了理论机制,但没有实证估计或量化案例研究。
核心观点
- 当攻击者持有与受影响状态相关的经济权益时,可通过自行发起的交易操纵永续资金费率。
- 提交后揭示的排序机制可能阻止自适应套利者在信息封闭阶段纠正操纵。
- 纠偏取决于交易者面临的价格冲击和库存成本,也取决于协议信息何时可用。
- 交易隐私可能削弱可预测资金费率反映到入场价格中的程度,从而放大资金费率失真。
- 所提安全指数区分攻击者信息盲区、纠偏保护和价格资本化保护。

# Reveal, Correct, Then Pay: Encrypted Mempools and Perpetual Funding Security # Reveal, Correct, Then Pay: Encrypted Mempools and Perpetual Funding Security Encrypted mempools are designed to hide transaction contents until execution order is fixed, preventing many victim dependent forms of maximal extractable value. This paper studies a different class of attack in the form of self-authored state manipulation, in which the attacker knows its own transaction and owns a downstream claim on the state that transaction changes. Perpetual futures funding is a canonical example. The funding signal determines a transfer rate, while receiving side open interest is the transfer base. In a commit then reveal mempool, an adaptive corrective transaction cannot enter the already committed batch. Privacy can therefore create an economic reaction gap even when cryptographic decryption overhead is negligible. We microfound correction through executable arbitrage opportunities. Correctors choose order size against local price impact and inventory cost, while the protocol information schedule determines which opportunities are actionable. The ordering barrier removes ordinary adaptive searchers from the closed stage. It therefore yields a closed stage correction rate below the adaptive correction rate whenever positive adaptive capacity becomes available after reveal. The distortion entering a funding window is multiplied by an explicit response factor. Transaction privacy can also reduce capitalization of predictable funding into entry prices, producing a second amplification channel. The resulting local security index separates attacker blindness, correction shielding, and capitalization shielding.
