### 1. About
|
||
|
|
btcd is a full node bitcoin implementation written in [Go](http://golang.org),
|
||
|
|
licensed under the [copyfree](http://www.copyfree.org) ISC License.
|
||
|
|
|
||
|
|
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 currently properly downloads, validates, and serves the block chain using the
|
||
|
|
exact rules (including bugs) for block acceptance as the reference
|
||
|
|
implementation, [bitcoind](https://github.com/bitcoin/bitcoin). We have taken
|
||
|
|
great care to avoid btcd causing a fork to the block chain. It passes all of
|
||
|
|
the '[official](https://github.com/TheBlueMatt/test-scripts/)' block acceptance
|
||
|
|
tests.
|
||
|
|
|
||
|
|
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 into the block chain and also includes the vast majority of the more
|
||
|
|
strict checks which filter transactions based on miner requirements ("standard"
|
||
|
|
transactions).
|
||
|
|
|
||
|
|
One key difference between btcd and bitcoind is that btcd does NOT include
|
||
|
|
wallet functionality and this was a very intentional design decision. See the
|
||
|
|
[blog entry](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.

### 2. Getting Started
|
||
|
|
|
||
|
|
<a name="Installation" />
|
||
|
|
**2.1 Installation**<br />
|
||
|
|
|
||
|
|
The first step is to install btcd. See one of the following sections for
|
||
|
|
details on how to install on the supported operating systems.
|
||
|
|
|
||
|
|
<a name="WindowsInstallation" />
|
||
|
|
**2.1.1 Windows Installation**<br />
|
||
|
|
|
||
|
|
* Install the MSI available at: https://github.com/btcsuite/btcd/releases
|
||
|
|
* Launch btcd from the Start Menu
|
||
|
|
|
||
|
|
<a name="PosixInstallation" />
|
||
|
|
**2.1.2 Linux/BSD/MacOSX/POSIX Installation**<br />
|
||
|
|
|
||
|
|
* Install Go according to the installation instructions here: http://golang.org/doc/install
|
||
|
|
* Run the following command to ensure your Go version is at least version 1.2: `$ go version`
|
||
|
|
* Run the following command to obtain btcd, its dependencies, and install it: `$ go get github.com/btcsuite/btcd/...`<br />
|
||
|
|
* To upgrade, run the following command: `$ go get -u github.com/btcsuite/btcd/...`
|
||
|
|
* Run btcd: `$ btcd`
|
||
|
|
|
||
|
|
<a name="Configuration" />
|
||
|
|
**2.2 Configuration**<br />
|
||
|
|
|
||
|
|
btcd has a number of [configuration](http://godoc.org/github.com/btcsuite/btcd)
|
||
|
|
options, which can be viewed by running: `$ btcd --help`.
|
||
|
|
|
||
|
|
<a name="BtcctlConfig" />
|
||
|
|
**2.3 Controlling and Querying btcd via btcctl**<br />
|
||
|
|
|
||
|
|
btcctl is a command line utility that can be used to both control and query btcd
|
||
|
|
via [RPC](http://www.wikipedia.org/wiki/Remote_procedure_call). btcd does
|
||
|
|
**not** enable its RPC server by default; You must configure at minimum both an
|
||
|
|
RPC username and password or both an RPC limited username and password:
|
||
|
|
|
||
|
|
* btcd.conf configuration file
|
||
|
|
```
|
||
|
|
[Application Options]
|
||
|
|
rpcuser=myuser
|
||
|
|
rpcpass=SomeDecentp4ssw0rd
|
||
|
|
rpclimituser=mylimituser
|
||
|
|
rpclimitpass=Limitedp4ssw0rd
|
||
|
|
```
|
||
|
|
* btcctl.conf configuration file
|
||
|
|
```
|
||
|
|
[Application Options]
|
||
|
|
rpcuser=myuser
|
||
|
|
rpcpass=SomeDecentp4ssw0rd
|
||
|
|
```
|
||
|
|
OR
|
||
|
|
```
|
||
|
|
[Application Options]
|
||
|
|
rpclimituser=mylimituser
|
||
|
|
rpclimitpass=Limitedp4ssw0rd
|
||
|
|
```
|
||
|
|
For a list of available options, run: `$ btcctl --help`
|
||
|
|
|
||
|
|
<a name="Mining" />
|
||
|
|
**2.4 Mining**<br />
|
||
|
|
btcd supports both the `getwork` and `getblocktemplate` RPCs although the
|
||
|
|
`getwork` RPC is deprecated and will likely be removed in a future release.
|
||
|
|
The limited user cannot access these RPCs.<br />
|
||
|
|
|
||
|
|
**1. Add the payment addresses with the `miningaddr` option.**<br />
|
||
|
|
|
||
|
|
```
|
||
|
|
[Application Options]
|
||
|
|
rpcuser=myuser
|
||
|
|
rpcpass=SomeDecentp4ssw0rd
|
||
|
|
miningaddr=12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX
|
||
|
|
miningaddr=1M83ju3EChKYyysmM2FXtLNftbacagd8FR
|
||
|
|
```
|
||
|
|
|
||
|
|
**2. Add btcd's RPC TLS certificate to system Certificate Authority list.**<br />
|
||
|
|
|
||
|
|
`cgminer` uses [curl](http://curl.haxx.se/) to fetch data from the RPC server.
|
||
|
|
Since curl validates the certificate by default, we must install the `btcd` RPC
|
||
|
|
certificate into the default system Certificate Authority list.
|
||
|
|
|
||
|
|
**Ubuntu**<br />
|
||
|
|
|
||
|
|
1. Copy rpc.cert to /usr/share/ca-certificates: `# cp /home/user/.btcd/rpc.cert /usr/share/ca-certificates/btcd.crt`<br />
|
||
|
|
2. Add btcd.crt to /etc/ca-certificates.conf: `# echo btcd.crt >> /etc/ca-certificates.conf`<br />
|
||
|
|
3. Update the CA certificate list: `# update-ca-certificates`<br />
|
||
|
|
|
||
|
|
**3. Set your mining software url to use https.**<br />
|
||
|
|
|
||
|
|
`$ cgminer -o https://127.0.0.1:8334 -u rpcuser -p rpcpassword`
|

**3.1 Startup**<br />
|
||
|
|
|
||
|
|
Typically btcd will run and start downloading the block chain with no extra
|
||
|
|
configuration necessary, however, there is an optional method to use a
|
||
|
|
`bootstrap.dat` file that may speed up the initial block chain download process.

**3.1 Wallet**<br />
|
||
|
|
|
||
|
|
btcd was intentionally developed without an integrated wallet for security
|
||
|
|
reasons. Please see [btcwallet](https://github.com/btcsuite/btcwallet) for more
