Install Instructions

Prerequisites

In order to build the full monorepo, the following is required:

Homebrew

MacOS users can install most required packages with Homebrew package manager.

For other operating systems, see the official install instructions for each required package (linked above).

Yarn

This will also install Node.js if it is not already installed.

brew install yarn

Ethereum tools

To install the go-ethereum suite with brew:

brew tap ethereum/ethereum
brew install ethereum

Jq (JSON query)

To install jq (JSON parsing binary):

brew install jq

git clone git@github.com:ParadigmFoundation/kosu-monorepo

Or via HTTP:

git clone https://github.com/ParadigmFoundation/kosu-monorepo

Build packages

Install dependencies:

yarn build

Documentation

Generated documentation is published for the following packages with each commit, and published to docs.kosu.io:

Documentation is also checked in to each package and viewable on GitHub.

Docker images

Various development images used for Kosu CI/CD and development are publicly available on GCR (download with docker pull), and built from each master commit.

kosu-io/node-ci

A custom Node.js (lts) image with additional binaries used to assist in building/testing Kosu packages. Drop-in replacement for node:lts image.

kosu-io/go-kosu-ci

A custom golang (1.13-stretch) image with Tendermint and other binaries pre-installed, used as the CI image for go-kosu (Tendermint is compiled into kosud and not needed for production builds, but used in testing).

kosu-io/kosu-geth

Contains geth with PoA consensus in a single-node private network configuration used for testing Kosu system contracts. Note that contracts are not pre-migrated and must be deployed with @kosu/system-contracts (see scripts).

Binaries

Pre-built binaries for go-kosu are available (per-commit CD builds are currently Linux/x86_64 only, build locally for other targets):

kosud

Kosu network client reference implementation, built on Tendermint consensus. Run kosud --help for usage.

wget https://storage.googleapis.com/kosud/linux_amd64/kosud
chmod +x kosud
install kosud /usr/local/bin

kosu-cli

Command-line interface for kosud (run kosu-cli for usage).

wget https://storage.googleapis.com/kosu-cli/linux_amd64/kosu-cli
chmod +x kosu-cli
install kosu-cli /usr/local/bin
