Kaspad

Warning: This is pre-alpha software. There's no guarantee anything works.

Kaspad is the reference full node Kaspa implementation written in Go (golang).

This project is currently under active development and is in a pre-Alpha state. Some things still don't work and APIs are far from finalized. The code is provided for reference only.

What is kaspa

Kaspa is an attempt at a proof-of-work cryptocurrency with instant confirmations and sub-second block times. It is based on the PHANTOM protocol, a generalization of Nakamoto consensus.

Requirements

Go 1.14 or later.

Installation

Build from Source

Install Go according to the installation instructions here: http://golang.org/doc/install
Ensure Go was installed properly and is a supported version:

$ go version

Run the following commands to obtain and install kaspad including all dependencies:

$ git clone https://github.com/kaspanet/kaspad
$ cd kaspad
$ go install . ./cmd/...

Kaspad (and utilities) should now be installed in $(go env GOPATH)/bin. If you did not already add the bin directory to your system path during Go installation, you are encouraged to do so now.

Getting Started

Kaspad has several configuration options available to tweak how it runs, but all of the basic operations work with zero configuration.

$ kaspad
