P2P Network Analysis

This is a Go web application that monitors connection metrics on the Bitcoin and Lightning networks, and saves the data to a SQLite database using GORM.

Prerequisites

• Go version 1.16 or later
• btcd: a full-node implementation of the Bitcoin protocol
• lnd: a Lightning Network Daemon implementation
• SQLite3: a lightweight database engine

Installation

1. Clone the repository to your local machine:

 git clone https://github.com/NonsoAmadi10/Heimdall

 cd Heimdall

2. Install the dependencies:

go mod download

3. Build the binary:

go build

Usage

1. Start a btcd node

btcd --testnet --rpcuser=rpcuser --rpcpass=rpcpass

2. Start a lightning node

lnd --bitcoin.testnet --bitcoin.rpcuser=rpcuser --bitcoin.rpcpass=rpcpass

3. Run the application:

./heimdall

The application will run in the background and collect connection metrics every minute, and save them to the metrics table in the metrics.db database file.

To view the metrics, you can open your postman on the following endpoints:

http://localhost:1700/node-info - Fetches node information for both bitcoin and lightning http://localhost:1700/conn-metrics - fetches metrics based on connection between your node and other peers as well as network bandwidth

Alternatively, there is a frontend metrics that gives visualization on the metrics generated. To view it simply:

1. Enter the frontend directory and install the node dependencies:

cd dashboard
yarn install 

2. Start the dev server:

yarn dev

3. Open your browser on http://localhost:3000

PS: I would be looking to add network hop messages, transaction blocks metrics and hashrate metrics
