The infrastructure of Randcast(DKG and Threshold-BLS based randomness service).
Build with cargo build (--release).
Test with cargo test --all -- --test-threads=1 --nocapture.
This repository contains several Rust crates and Solidity contracts that implement the different building blocks of Randcast. The high-level structure of the repository is as follows:
arpa-node: Rust crate that provides a long-running client and a CLI tool for the node operator.user-cli: Rust crate that provides a user side CLI tool to interact with the smart contracts.core: Rust crate that provides basic types, utilities and traits for the node and the CLI tool.contract-client: Rust crate that provides types and traits for interacting with the smart contracts.dal: Rust crate that provides the implementation of the data access layer.log: Rust crate that provides an attribute macro for logging at debug level.dkg-core: Rust crate that provides the implementation utilities for the DKG.threshold-bls: Rust crate that provides the implementation of threshold BLS signatures for BN254 and BLS12-381.contracts: Solidity contracts including Controller, Adapter, Coordinator, libraries and scripts for deployment and testing.
Rust crates dkg-core, threshold-bls and Solidity contracts under libraries/ have been adapted from the following resources:
