Reverie

Reverie is an implementation (prover and verifier) of the MPC-in-the-head NIZKPoK outlined in Improved Non-Interactive Zero Knowledge with Applications to Post-Quantum Signatures. Reverie seeks to offer concrete prover efficiency (linear proving time with small constants) for complex predicates. The implementation seeks to offer 128-bits of (classical) security and support arbitrary rings, most efficiently Z₂, Z₈, Z₁₆, Z₃₂ and Z₆₄.

Reverie provides both a library (with a simplified and a streaming interface), in addition to a "companion" program for proving/verifying statements specified in Bristol format to enable easy experimentation.

Building

Reverie requires a relatively recent nightly Rust.
