bsvd

bsvd is a full node Bitcoin (BSV) implementation written in Go (golang).

This project is a port of the bchd codebase to Bitcoin (BSV). 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.

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

Requirements

Go 1.9 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 btcd, all dependencies, and install it:

$ go get github.com/whatsonchain/bsvd

This will download and compile bsvd and put it in your path.

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

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

Getting Started

To start bsvd with default options just run:

$ ./bsvd

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

Docker

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

docker build . -t bsvd

To run the image:

docker run bsvd

To run bsvctl and connect to your bsvd instance:

# Find the running bsvd container.
docker ps

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

Documentation

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

Overview

Code generated by go-bindata. (@generated) DO NOT EDIT. sources: sample-bsvd.conf

bsvd is a full-node Bitcoin (BSV) implementation written in Go.

The default options are sane for most users. This means bsvd will work 'out of the box' for most users. However, there are also a wide variety of flags that can be used to control it.

The following section provides a usage overview which enumerates the flags. An interesting point to note is that the long form of all of these options (except -C) can be specified in a configuration file that is automatically parsed when bsvd starts up. By default, the configuration file is located at ~/.bsvd/bsvd.conf on POSIX-style operating systems and %LOCALAPPDATA%\bsvd\bsvd.conf on Windows. The -C (--configfile) flag, as shown below, can be used to override this location.

Usage:
