dcrd

dcrd is a Decred full node implementation written in Go (golang).

This acts as a chain daemon for the Decred cryptocurrency. dcrd maintains the entire past transactional ledger of Decred and allows relaying of transactions to other Decred nodes across the world. To read more about Decred please see the project documentation.

Note: To send or receive funds and join Proof-of-Stake mining, you will also need dcrwallet.

This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use since February 2016.

It is forked from btcd which is a bitcoin full node implementation written in Go. btcd is a ongoing project under active development. Because dcrd is constantly synced with btcd codebase, it will get the benefit of btcd's ongoing upgrades to peer and connection handling, database optimization and other blockchain related technology improvements.

Requirements

Go 1.7 or newer.

Getting Started

• dcrd (and utilities) will now be installed in either $GOROOT/bin or $GOPATH/bin depending on your configuration. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.

Updating

Windows

Install a newer MSI

Linux/BSD/MacOSX/POSIX - Build from Source

• Dep

  Dep is used to manage project dependencies and provide reproducible builds. To install:

  go get -u github.com/golang/dep/cmd/dep

Unfortunately, the use of dep prevents a handy tool such as go get from automatically downloading, building, and installing the source in a single command. Instead, the latest project and dependency sources must be first obtained manually with git and dep, and then go is used to build and install the project.

Getting the source:

For a first time installation, the project and dependency sources can be obtained manually with git and dep (create directories as needed):

git clone https://github.com/decred/dcrd $GOPATH/src/github.com/decred/dcrd
cd $GOPATH/src/github.com/decred/dcrd
dep ensure
go install . ./cmd/...

To update an existing source tree, pull the latest changes and install the matching dependencies:

cd $GOPATH/src/github.com/decred/dcrd
git pull
dep ensure
go install . ./cmd/...

Docker

All tests and linters may be run in a docker container using the script run_tests.sh. This script defaults to using the current supported version of go. You can run it with the major version of go you would like to use as the only arguement to test a previous on a previous version of go (generally decred supports the current version of go and the previous one).

./run_tests.sh 1.8

To run the tests locally without docker:

./run_tests.sh local
