This is mostly a backport of some of the same modifications made in Decred along with a few additional things cleaned up. In particular, this updates the code to make use of the new chainhash package. Also, since this required API changes anyways and the hash algorithm is no longer tied specifically to SHA, all other functions throughout the code base which had "Sha" in their name have been changed to Hash so they are not incorrectly implying the hash algorithm. The following is an overview of the changes: - Remove the wire.ShaHash type - Update all references to wire.ShaHash to the new chainhash.Hash type - Rename the following functions and update all references: - wire.BlockHeader.BlockSha -> BlockHash - wire.MsgBlock.BlockSha -> BlockHash - wire.MsgBlock.TxShas -> TxHashes - wire.MsgTx.TxSha -> TxHash - blockchain.ShaHashToBig -> HashToBig - peer.ShaFunc -> peer.HashFunc - Rename all variables that included sha in their name to include hash instead - Update for function name changes in other dependent packages such as btcutil - Update copyright dates on all modified files - Update glide.lock file to use the required version of btcutil |

### 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 since October 2013.
It currently properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as the reference implementation, bitcoind. We have taken great care to avoid btcd causing a fork to the block chain. It passes all of the 'official' 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 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.
### 2. Getting Started **2.1 Installation**The first step is to install btcd. See one of the following sections for details on how to install on the supported operating systems.
**2.1.1 Windows Installation**- Install the MSI available at: https://github.com/btcsuite/btcd/releases
- Launch btcd from the Start Menu
-
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.
Updating
- 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/...
**2.1.2.1 Gentoo Linux Installation**- Install Layman and enable the Bitcoin overlay.
- https://gitlab.com/bitcoin/gentoo
- Copy or symlink
/var/lib/layman/bitcoin/Documentation/package.keywords/btcd-live
to/etc/portage/package.keywords/
- Install btcd:
$ emerge net-p2p/btcd
btcd has a number of configuration
options, which can be viewed by running: $ btcd --help
.
btcctl is a command line utility that can be used to both control and query btcd via RPC. 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
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.
1. Add the payment addresses with the miningaddr
option.
[Application Options]
rpcuser=myuser
rpcpass=SomeDecentp4ssw0rd
miningaddr=12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX
miningaddr=1M83ju3EChKYyysmM2FXtLNftbacagd8FR
2. Add btcd's RPC TLS certificate to system Certificate Authority list.
cgminer
uses curl 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
- Copy rpc.cert to /usr/share/ca-certificates:
# cp /home/user/.btcd/rpc.cert /usr/share/ca-certificates/btcd.crt
- Add btcd.crt to /etc/ca-certificates.conf:
# echo btcd.crt >> /etc/ca-certificates.conf
- Update the CA certificate list:
# update-ca-certificates
3. Set your mining software url to use https.
$ cgminer -o https://127.0.0.1:8334 -u rpcuser -p rpcpassword
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.
