ipfs-bch-wallet-service

This is a censorship-resistant, IPFS-based microservice that provides access for wallets to access the Bitcoin Cash (BCH) blockchain. It leverages bch-js.

About This Repository

This repository is forked from the ipfs-service-provider repository. That code has been customized to provide BCH blockchain access for wallets. This server-side node.js app provides both REST API over HTTP and JSON RPC over IPFS endpoints for wallets to access the blockchain through.

As part of the end-to-end testing, a virtual client can be started that will interrogate every endpoint provided by this API server. This client can be forked by developers to write their own apps that use this IPFS-based service.

Roadmap

This repository is one step in a longer path. Here are the major milestones of this path:

• Add wallet-based calls to ipfs-bch-wallet-service (this repository).
• Create a miniature version of bch-js that makes calls over JSON RPC (bch-js-ipfs).
• Given a variable, minimal-slp-wallet could call bch-js or bch-js-ipfs for network calls.
• Fork slp-cli-wallet and add daemon feature to spin up IPFS node and work with bch-js-ipfs.

Requirements

• node ^16.20.2
• npm ^8.19.4
• Docker ^20.10.8
• Docker Compose ^1.27.4

Installation

Development Environment

Note: This software now uses an external go-ipfs IPFS node. The instructions below have not been updated to reflect this.

A development environment will allow you modify the code on-the-fly and contribute to the code base of this repository. PM2 is recommended for running this code base as an IPFS Circuit Relay.
