This sync includes a new service flag named SFNodeBloom that a node is required to use to indicate that it supports bloom filtering. This includes a protocol version bump to 2 and a wire version bump to 0.1.0. dcrd: The SFNodeBloom flag is set by default. A new configuration option --nopeerbloomfilters has been added to to disable bloom filtering. Also, it corrects an issue with the mining state message where it was using the network protocol version instead of having its own version. |

dcrd
dcrd is a Decred full node 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 dcrd 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 dcrd and Bitcoin Core is that dcrd 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 dcrd. That functionality is provided by the dcrwallet and btcgui projects which are both under active development.
Requirements
Go 1.3 or newer.
Installation
Windows - MSI Available
https://github.com/decred/dcrd/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:
$ 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.
- Run the following command to obtain dcrd, all dependencies, and install it:
$ go get -u github.com/decred/dcrd/...
- dcrd (and utilities) will now be installed in either
$GOROOT/binor$GOPATH/bindepending 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/MacOSX/POSIX - Build from Source
- Run the following command to update dcrd, all dependencies, and install it:
$ go get -u -v github.com/decred/dcrd/...
Getting Started
dcrd 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 dcrd from your Start menu.
Linux/BSD/POSIX/Source
$ ./dcrd
