[] (https://travis-ci.org/btcsuite/btcd)
btcd is an alternative full node bitcoin implementation written in Go (golang).
This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use since October 2013.
It properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as Bitcoin Core. We have taken great care to avoid btcd causing a fork to the block chain. It passes all of the 'official' block acceptance tests (https://github.com/TheBlueMatt/test-scripts) as well as all of the JSON test data in the Bitcoin Core code.
It also relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all transactions admitted to the pool follow the rules required by the block chain and also includes the same checks which filter transactions based on miner requirements ("standard" transactions) as Bitcoin Core.
One key difference between btcd and Bitcoin Core is that btcd does NOT include wallet functionality and this was a very intentional design decision. See the blog entry here for more details. This means you can't actually make or receive payments directly with btcd. That functionality is provided by the btcwallet and Paymetheus (Windows-only) projects which are both under active development.
Go 1.5 or newer.
https://github.com/btcsuite/btcd/releases
-
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
$ go env GOROOT GOPATH
NOTE: The GOROOT
and GOPATH
above must not be the same path. It is
recommended that GOPATH
is set to a directory in your home directory such as
~/goprojects
to avoid write permission issues. It is also recommended to add
$GOPATH/bin
to your PATH
at this point.
NOTE: If you are using Go 1.5, you must manually enable the vendor
experiment by setting the GO15VENDOREXPERIMENT
environment variable to 1
.
This step is not required for Go 1.6.
- Run the following commands to obtain btcd, all dependencies, and install it:
$ go get -u github.com/Masterminds/glide
$ git clone https://github.com/btcsuite/btcd $GOPATH/src/github.com/btcsuite/btcd
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ glide install
$ go install . ./cmd/...
- btcd (and utilities) will now be installed in
$GOPATH/bin
. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.
Install a newer MSI
- Run the following commands to update btcd, all dependencies, and install it:
$ cd $GOPATH/src/github.com/btcsuite/btcd
$ git pull && glide install
$ go install . ./cmd/...
btcd has several configuration options avilable to tweak how it runs, but all of the basic operations described in the intro section work with zero configuration.
Launch btcd from your Start menu.
