This modifies the results provided by the getrawtransaction and searchrawtransactions RPCs to make them consistent with each other. In particular, it adds the transaction expiry, block height, and block index fields to the searchrawtransactions result and ensures that both omit the block height when it is zero so that it is not included in the results for mempool transactions. Since populating the block index requires additional details to be stored to the transaction index to efficiently provide, only the infrastructure is added and the value is left as the default for now, which means it will be omitted and therefore not change the visible behavior. Finally, it also updates the RPC server help to provide consistent descriptions for the fields and also updates the JSON-RPC documentation. |

dcrd
dcrd is a Decred full node implementation written in Go (golang).
This acts as a chain daemon for the Decred cryptocurrency. dcrd maintains the entire past transactional ledger of Decred and allows relaying of transactions to other Decred nodes across the world. To read more about Decred please see the project documentation.
Note: To send or receive funds and join Proof-of-Stake mining, you will also need dcrwallet.
This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use since February 2016.
It is forked from btcd which is a bitcoin full node implementation written in Go. btcd is a ongoing project under active development. Because dcrd is constantly synced with btcd codebase, it will get the benefit of btcd's ongoing upgrades to peer and connection handling, database optimization and other blockchain related technology improvements.
Requirements
Go 1.9 or newer.
Getting Started
- 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
-
Dep
Dep is used to manage project dependencies and provide reproducible builds. To install:
go get -u github.com/golang/dep/cmd/dep
Unfortunately, the use of dep prevents a handy tool such as go get from
automatically downloading, building, and installing the source in a single
command. Instead, the latest project and dependency sources must be first
obtained manually with git and dep, and then go is used to build and
install the project.
Getting the source:
For a first time installation, the project and dependency sources can be
obtained manually with git and dep (create directories as needed):
git clone https://github.com/decred/dcrd $GOPATH/src/github.com/decred/dcrd
cd $GOPATH/src/github.com/decred/dcrd
dep ensure
go install . ./cmd/...
To update an existing source tree, pull the latest changes and install the matching dependencies:
cd $GOPATH/src/github.com/decred/dcrd
git pull
dep ensure
go install . ./cmd/...

Docker
Running dcrd
You can run a decred node from inside a docker container. To build the image yourself, use the following command:
docker build -t decred/dcrd .
Or you can create an alpine based image (requires Docker 17.05 or higher):
docker build -t decred/dcrd:alpine -f Dockerfile.alpine .
You can then run the image using:
docker run decred/dcrd
You may wish to use an external volume to customise your config and persist the data in an external volume:
docker run --rm -v /home/user/dcrdata:/root/.dcrd/data decred/dcrd
For a minimal image, you can use the decred/dcrd:alpine tag. This is typically a more secure option while also being a much smaller image.
You can run dcrctl from inside the image. For example, run an image (mounting your data from externally) with:
docker run --rm -ti --name=dcrd-1 -v /home/user/.dcrd:/root/.dcrd \
decred/dcrd:alpine
And then run dcrctl commands against it. For example:
docker exec -ti dcrd-1 dcrctl getbestblock
Running Tests
All tests and linters may be run in a docker container using the script
run_tests.sh. This script defaults to using the current supported version of
go. You can run it with the major version of Go you would like to use as the
only arguement to test a previous on a previous version of Go (generally Decred
supports the current version of Go and the previous one).
./run_tests.sh 1.9
To run the tests locally without docker:
./run_tests.sh local
