EMP-zk

arm x86 Total alerts Language grade: C/C++

Protocols

The code in this repo implements a fast, scalable, communication-efficient zero-knowledge proof protocol for Boolean/arithmetic circuits and polynomials. The protocols are described in Wolverine, Quicksilver and Mystique.

Installation

  1. wget https://raw.githubusercontent.com/emp-toolkit/emp-readme/master/scripts/install.py
  2. python[3] install.py --deps --tool --ot --zk
    1. By default it will build for Release. -DCMAKE_BUILD_TYPE=[Release|Debug] option is also available.
    2. No sudo? Change CMAKE_INSTALL_PREFIX.

Test

Testing on localhost

./run ./bin/[binary]

Testing on two

  1. Change the IP address in the test code

  2. run ./bin/[binary] 1 [port] on one machine and

    run ./bin/[binary] 2 [port] on the other machine.

Performance

The test is done by two AWS EC2 m5.2xlarge servers with throttled network.

Throughput of circuit-based ZK protocol

All values are for "million gates per second".
