bchd

bchd is an alternative full node bitcoin cash implementation written in Go (golang).

This project is a port of the btcd codebase to Bitcoin Cash. It provides a high powered and reliable blockchain server which makes it a suitable backend to serve blockchain data to lite clients and block explorers or to power your local wallet.

bchd does not include any wallet functionality by design as it makes the codebase more modular and easy to maintain. The bchwallet is a separate application that provides a secure Bitcoin Cash wallet that communicates with your running bchd instance via the API.

Requirements

Go 1.23.4 or newer.

Install

Install Pre-built Packages

The easiest way to run the server is to download a pre-built binary. You can find binaries of our latest release for each operating system at the releases page.

Build from Source

If you prefer to install from source do the following:

Install Go according to the installation instructions here: http://golang.org/doc/install
Run the following commands to obtain bchd, all dependencies, and install it:

go get github.com/gcash/bchd

This will download the source code into your GOPATH and compile bchd and install it in your path.

For developers if you wish to place the working directory outside your GOPATH you can do so with Go >=1.12.x as follows:

mkdir workspace
cd workspace
git clone https://github.com/gcash/bchd.git
cd bchd
go install (or build or run, etc)

Dependencies will be automatically installed to $GOPATH/pkg/mod.

If you are a bchd contributor and would like to change the default config file (bchd.conf), make any changes to sample-bchd.conf and then run the following commands:

go-bindata sample-bchd.conf  # requires github.com/go-bindata/go-bindata/
gofmt -s -w bindata.go

Getting Started

To start bchd with default options just run:

./bchd

You'll find a large number of runtime options with the help flag. All of them can also be set in a config file. See the sample config file for an example of how to use it.

./bchd --help

You can use the common json RPC interface through the bchctl command:

./bchctl --help

./bchctl --listcommands

Bchd separates the node and the wallet. Commands for the wallet will work when you are also running bchwallet:

./bchctl -u username -P password --wallet getnewaddress

Docker

Building and running bchd in docker is quite painless. To build the image:

docker build . -t bchd

To run the image:

# Use stop-timeout to make sure the container exits cleanly!
docker run --stop-timeout=1200 bchd

To run bchctl and connect to your bchd instance:

# Find the running bchd container.
docker ps

# Exec bchctl.
docker exec <container> bchctl <command>

The documentation is a work-in-progress. It is located in the docs folder.
