Getting started

Prerequisites

To run this node, you must have the follow software installed on your local machine:

• Docker (including docker-compose)
• Python 3
• Virtualenv (sudo apt install python3-venv)
• Openssl
• Git

Cloning this repository

# Clone repository
git clone https://github.com/ActorForth/bch-devsuite.git
cd ./bch-devsuite

# Setup virtualenv
python3 -m venv venv
source ./venv/bin/activate

# Install script dependencies
pip install -r requirements.txt

Setup infrastructure

This will check that the necessary software is installed, and then it will download and prepare the docker containers. For a full list of options, run ./setup with no arguments to see its usage.

NOTE: If you wish to have any custom changes applied to the Bitcoin Unlimited, or REST API services, be sure to apply those changes within the bitcoin.conf, fulcrum-config.conf, or restapi-config.sh files, respectively, before executing the setup script. Bitcoin Cash Node can alternatively be used with fulcrum, by commenting out bitcoin unlimited and uncommenting bitcoin cash node and fulcrum. These can not currently run simultaneously, and one or the other must be used.

./bch-devsuite init
# First we select a network, which must be regtest, mainnet or testnet
# Next we specify the node, bitcoin unlimited or bitcoincash node
# Next we select a rest interface, bchrest is a fork of the rest.bitcoin.com api, while bchapi is a rest utilized with the bch-js library
# Slp is optional, selecting this option enables slpdb, slpserve and mongodb
# Smartbch is optional, if the network is regtest, this also generate 10 test keys.

NOTE: A RPC password and username prompt will appear for the node, these values will be stored in generated docker-compose.yml file.

NOTE: The SLP option will prompt the user to input a MONGODB username and password, this is to prevent external parties from modifying your database if the ports are exposed.

Running infrastructure

Execute the services script to start the node, indexer, rest API, and/or SLPDB (depending which ones chose in the setup script).

./bch-devsuite start

Testing

./bitcoin-cli getblockchaininfo

Stop infrastructure

Once you decide to call it a day, you can shut down your local environment by executing:

./bch-devsuite stop

Cleaning Up

If you experience any issues, or would like to completely erase the current wallet and node containers, run the following script:

./clean

NOTE: this command may need to be ran with sudo while on linux

WARNING: The 'clean' script is very destructive, so make sure you only use it when you want to completely erase the entire current instance of nodes and the wallet.

Setup Option Reference

Network

• Regtest
• Testnet
• Mainnet

Component

• Local node (Bitcoin Unlimited node or Bitcoin Cash Node)
• REST service (A rest.bitcoin.com-compatible or Bch-API)
• SLP services (SLPDB, slpserve)
• SmartBCH (https://smartbch.org/ Currently only support regtest)

Local node

• Bitcoin Unlimited Node
• Bitcoin Cash Node

REST Service

• bchrest (rest.bitcoin.com)
• bchapi (https://api.fullstack.cash/docs/)

Architecture

Two REST APIs can be run: rest.bitcoin.com and bch-api.

1. rest.bitcoin.com tech stack

All these components work together in a stack, which means that if the lower part is missing then some of the API in rest.bitcoin.com might not function properly.

The main reason why you should use all of our fork stacks is because we maintain and guarantee that all of the components will work well with the Regtest address format. Allowing you to test locally more easily.

The blue part is the node that you choose. The default node is Bitcoin unlimited and there is Bitcoin Cash node as an option as well. Currently, this node is always required.

The red part is an indexer. ElectrsCash is for indexing Bitcoin cash transactions and aggregate BCH balance per address. Without these, you won't be able to query the amount of BCH you own in a particular address. OpenSight is a shim micro service to make ElectrsCash compatible with rest.bitcoin.com API interface. SLPDB is an indexer for SLP token, color coin on top of Bitcoin Cash, this will be verified if the data relate to the color coin is valid and checks if the coin follows the SLP off-chain consensus.

The orange part is rest.bitcoin.com API, a unified interface for anyone to interact with all of these complex services through REST API interface uniformly

The green part is the client SDK that will interact with rest.bitcoin.com interface. Bitcash is written in Python and Bitbox is written in typescript.

2. Chris Troutner JS tech stack

The main difference is the rest interface. bch-api has a different API from rest.bitcoin.com and can talk directly to Electrscash without requiring the shim.

About

This repo intends to be a toolkit for running a local version of a Bitcoin Unlimited for development and testing purposes. Currently it provides a self-hosted local node, indexer (Electrs), a drop-in Ninsight replacement (Opensight), a regtest version of the rest.bitcoin.com REST APIs, an instance of SLPDB for token querying.

Known Issues

There are a few issues with this setup that could use improvement in the future.

• Currently, this setup relies on the built-in Electrscash indexing server included in the Bitcoin Unlimited node. This isn't an issue per se, but to test with other nodes (such as Bitcoin ABC, Bitcoin Cash Node, or bchd) it will be necessary to seperate the indexing server into a seperate container.
• Currently blocks must be generated manually after transactions are made in order to mine them into blocks. The possibility of adding an automation to generate a block every few minutes could be a consideration to look into.
