Zcash Foundation FROST Demos

This will be part of a set of demos and a proof of concept application that uses the FROST libraries and reference implementation. The purpose of these demos is to:

  1. identify gaps in our documentation
  2. provide usage examples for developer facing documentation
  3. provide reference implementations for developers wanting to use FROST in a “real world” scenario.

This demo uses the (Ed25519, SHA-512) ciphersuite. The crate can be found here.

About FROST (Flexible Round-Optimised Schnorr Threshold signatures)

Unlike signatures in a single-party setting, threshold signatures require cooperation among a threshold number of signers, each holding a share of a common private key. The security of threshold schemes in general assume that an adversary can corrupt strictly fewer than a threshold number of participants.

Two-Round Threshold Schnorr Signatures with FROST presents a variant of a Flexible Round-Optimized Schnorr Threshold (FROST) signature scheme originally defined in FROST20. FROST reduces network overhead during threshold signing operations while employing a novel technique to protect against forgery attacks applicable to prior Schnorr-based threshold signature constructions. This variant of FROST requires two rounds to compute a signature, and implements signing efficiency improvements described by Schnorr21. Single-round signing with FROST is not implemented here.

Projects

This repo contains 4 projects:

  1. Trusted Dealer
  2. DKG
  3. Coordinator
  4. Participant

Status ⚠

Trusted Dealer demo - WIP DKG demo - WIP Coordinator demo - WIP Participant demo - WIP

Usage

NOTE: This is for demo purposes only and should not be used in production.

You will need to have Rust and Cargo installed.

To run:

  1. Clone the repo. Run git clone https://github.com/ZcashFoundation/frost-zcash-demo.git
  2. Run cargo install

and in separate terminals: 3. Run cargo run --bin trusted-dealer or cargo run --bin dkg 4. Run cargo run --bin coordinator 5. Run cargo run --bin participants. Do this in separate terminals for separate participants.

Developer Information

Pre-commit checks

  1. Run cargo make all

Coverage

Test coverage checks are performed in the pipeline. This is configured here: .github/workflows/coverage.yaml To run these locally:

  1. Install coverage tool by running cargo install cargo-llvm-cov
  2. Run cargo make cov (you may be asked if you want to install llvm-tools-preview, if so type Y)
