|
|
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 for over 6 months as of May
|
|
2014, however there are still a couple of major features we want to add before
|
|
we come out of beta.
|
|
|
|
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](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
|
|
[btcgui](https://github.com/btcsuite/btcgui) projects which are both under
|
|
active development.
|
|
|
|
## Requirements
|
|
|
|
[Go](http://golang.org) 1.2 or newer.
|
|
|
|
## Installation
|
|
|
|
#### Windows - MSI Available
|
|
|
|
https://github.com/conformal/btcd/releases
|
|
|
|
#### Linux/BSD/POSIX - Build from Source
|
|
|
|
- Install Go according to the installation instructions here:
|
|
http://golang.org/doc/install
|
|
|
|
- Run the following command to obtain btcd, all dependencies, and install it:
|
|
```$ go get github.com/conformal/btcd/...```
|
|
|
|
- btcd (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/POSIX - Build from Source
|
|
|
|
- Run the following command to update btcd, all dependencies, and install it:
|
|
```$ go get -u -v github.com/conformal/btcd/...```
|
|
|
|
## Getting Started
|
|
|
|
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.
|
|
|
|
#### Windows (Installed from MSI)
|
|
|
|
Launch btcd from your Start menu.
|
|
|
|
#### Linux/BSD/POSIX/Source
|
|
|
|
```bash
|
|
$ ./btcd
|
|
````

## Issue Tracker
|
|
|
|
The [integrated github issue tracker](https://github.com/conformal/btcd/issues)
|
|
is used for this project.
|
|
|
|
## Documentation
|
|
|
|
The documentation is a work-in-progress. It uses the [github wiki](https://github.com/conformal/btcd/wiki) facility.
|
|
|
|
## 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 Conformal. To verify the
|
|
signature perform the following:
|
|
|
|
- Download the public key from the Conformal website at
|
|
https://opensource.conformal.com/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
|
|
```
