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 consensus bugs) for block acceptance as Bitcoin Core. We have
|
|
taken great care to avoid btcd causing a fork to the block chain. It includes a
|
|
full block validation testing framework which contains all of the 'official'
|
|
block acceptance tests (and some additional ones) that is run on every pull
|
|
request to help ensure it properly follows consensus. Also, it passes all of
|
|
the JSON test data in the Bitcoin Core code.
|
|
|
|
It also properly relays newly mined blocks, maintains a transaction pool, and
|
|
relays individual transactions that have not yet made it into a block. It
|
|
ensures all individual transactions admitted to the pool follow the rules
|
|
required by the block chain and also includes more strict checks which filter
|
|
transactions based on miner requirements ("standard" transactions).
|
|
|
|
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](https://blog.conformal.com/btcd-not-your-moms-bitcoin-daemon)
|
|
for more details. This means you can't actually make or receive payments
|
|
directly with btcd. That functionality is provided by the
|
|
[btcwallet](https://github.com/btcsuite/btcwallet) and
|
|
[Paymetheus](https://github.com/btcsuite/Paymetheus) (Windows-only) projects
|
|
which are both under active development.
|
|
|
|
## Requirements
|
|
|
|
[Go](http://golang.org) 1.8 or newer.
|
|
|
|
## Installation
|
|
|
|
#### Windows - MSI Available
|
|
|
|
https://github.com/btcsuite/btcd/releases
|
|
|
|
#### Linux/BSD/MacOSX/POSIX - 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:
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
- Run the following commands to obtain btcd, all dependencies, and install it:
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
## Updating
|
|
|
|
#### Windows
|
|
|
|
Install a newer MSI
|
|
|
|
#### Linux/BSD/MacOSX/POSIX - Build from Source
|
|
|
|
- Run the following commands to update btcd, all dependencies, and install it:
|
|
|
|
```bash
|
|
$ cd $GOPATH/src/github.com/btcsuite/btcd
|
|
$ git pull && glide install
|
|
$ go install . ./cmd/...
|
|
```
|
|
|
|
## Getting Started
|
|
|
|
btcd has several configuration options available to tweak how it runs, but all
|
|
of the basic operations described in the intro section work with zero
|
|
configuration.
|
|
|
|
#### Windows (Installed from MSI)
|
|
|
|
Launch btcd from your Start menu.
|
|
|
|
#### Linux/BSD/POSIX/Source
|
|
|
|
```bash
|
|
$ ./btcd
|
|
```

## GPG Verification Key
|
|
|
|
All official release tags are signed by Conformal so users can ensure the code
|
|
has not been tampered with and is coming from the btcsuite developers. To
|
|
verify the signature perform the following:
|
|
|
|
- Download the Conformal public key:
|
|
https://raw.githubusercontent.com/btcsuite/btcd/master/release/GIT-GPG-KEY-conformal.txt
|
|
|
|
- Import the public key into your GPG keyring:
|
|
```bash
|
|
gpg --import GIT-GPG-KEY-conformal.txt
|
|
```
|
|
|
|
- Verify the release tag with the following command where `TAG_NAME` is a
|
|
placeholder for the specific tag:
|
|
```bash
|
|
git tag -v TAG_NAME
|
|
```
