TL;DR
This paper fills the gap in provable anonymity guarantees for Zcash and Firo under the compromise of the incoming viewing key, while, at the same time, exposing problems with Monero.
Dark pools are designed to provide pre-trade privacy, liveness, and post-trade confidentiality - concealing order flow before execution and limiting information leakage after. Decentralized dark pools, such as Renegade, aim to replicate these properties without custodial risk, using secure multi-party computation (MPC)...
Ephemeral coin tracing (ECT) is introduced, a primitive whose tracing capacity is bounded by construction, both in the number of simultaneously traced users and in the number of hops each trace survives.
The voice anonymization community mainly uses Equal Error Rate (EER) to evaluate the performance of voice identity protection. While alternative metrics such as privacy-ZEBRA and a rank-based metric have been proposed, their underlying assumptions and differences may not be well known, especially to newcomers. This pap...
A layered system model and an analysis pipeline that uses prior history as the temporal baseline, applies cumulative pruning and cross-proof propagation to each proof's Commitment Set, and recursively traces the survivors through historical hidden-state transitions to derive the final transaction-level Anonymity Set Si...
Lacan is proposed, a protocol that reconciles anonymity and accountability within a realistic design, grounded in a novel chain of successor proofs for accountable path reconstruction, together with traceable signatures, path validation, and key-committing encryption.
