Extending Blockchain Untraceability with Plausible Deniability

Eunchan Park, Kyonghwa Song, Min Suk Kang, Won Hoi Kim, Wonho Song

Blockchain transfers can be hidden by staging them to look like ordinary DeFi losses from sandwich attacks or arbitrage.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

DCAT transfers are syntactically identical to corresponding MEV activities, classified as ordinary extractions by standard MEV detection tools, and leave the sender and receiver unlinked under representative forensic tools.

C2weakest assumption

That the staged DCAT events remain indistinguishable from genuine MEV activity under real-world economic semantics and that power-law distributions in MEV losses are stable enough to prevent reliable fixed-threshold detection.

C3one line summary

DCAT hides asset transfers by making them appear as typical MEV losses like sandwiches and arbitrages, rendering them syntactically identical to normal DeFi activity and providing plausible deniability.
