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

This acts as a chain daemon for the [Decred](https://decred.org) 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](https://docs.decred.org/#overview).

Note: To send or receive funds and join Proof-of-Stake mining, you will also need
[dcrwallet](https://github.com/decred/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](https://github.com/btcsuite/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](http://golang.org) 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/...
```

For more information about decred and how to set up your software please go to
our docs page at [docs.decred.org](https://docs.decred.org/getting-started/beginner-guide/).

## 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
```
