Getting Started 🛠️

Prerequisites

Before you dive into setting up the zkLocus Integration Oracle, make sure you have the following:

Node.js (14.x or later)
npm or yarn package manager
Access to command line/terminal
Basic understanding of TypeScript and Node.js environments

Installation and Running zkLocus Integration Oracle

You can either install the zkLocus Integration Oracle from npm or clone the repository and build it yourself. Both approaches come with an easy-to-use setup and configuration process, allowing you to get started quickly.

npm Installation

The zkLocus Integration Oracle can be easily installed and run using npm, the Node package manager. This section will guide you through the installation process and demonstrate how to run the Oracle. To install the zkLocus Integration Oracle from npm, run the following command:

Multi-Step Installation:

Install the Package:
First, install the package using npm:
```
npm install zklocus-integration-oracle
```
This command downloads the package and all necessary dependencies.
Build the Project:
Before running the project, you might need to build it, especially if it's written in TypeScript and requires compilation. However, if the package is distributed pre-compiled, you can skip this step.
```
npm run build
```
Run the Oracle:
Start the server using the provided executable script:
```
npx zklocus-oracle
```
Or, if you've installed the package globally or used npm link, you can start it directly:
```
zklocus-oracle
```

Single-Step Installation and Running:

For a more streamlined setup, you can install and run the server globally in one command. This approach is handy for quick installations and getting the server up and running with minimal steps.

Global Install & Run:
```
npm install -g zklocus-integration-oracle && zklocus-oracle
```
This command installs the package globally and then runs the zklocus-oracle executable, starting your server.

Running the Executable

After installation, the zklocus-oracle executable will be available in your environment. You can run the server with customizable parameters if supported:

zklocus-oracle --ip 127.0.0.1 --port 3000

Replace 127.0.0.1 and 3000 with the IP address and port you wish to use.

Cloning the Repository/Building from Source

Follow these steps to get your Integration Oracle up and running:

Clone the Repository: git clone https://github.com/your-repository/zklocus-integration-oracle.git
Navigate to the Directory: cd zklocus-integration-oracle
Install Dependencies: npm install or yarn install
Build the Project (if necessary): npm run build

Verifying Installation

To verify that the server is running correctly, you can send a test request and check the logs for any startup messages.

Configuration

Before starting the server, configure it to fit your setup:

Set environmental variables for sensitive information like private keys.
Use command-line arguments to specify IP address, port, and endpoint (--ip, --port, --endpoint).

Usage 💻

The zkLocus Integration Oracle server can be run in two primary ways:

Direct Executable via npm: Utilizing the zklocus-oracle command or npx zklocus-oracle for a quick start.
Npm Command: Using scripts defined in the package.json file, such as npm start or npm run dev for more customized runs or development purposes.

Starting the Server as an Executable

Direct Executable

Once installed, you can run the zkLocus Integration Oracle as an executable directly from your terminal. This method is swift and doesn't require navigating to the project directory.

Run Globally: If you've installed the package globally using npm install -g zklocus-integration-oracle, you can start the server using:
```
zklocus-oracle
```
Run without Global Installation: If you prefer not to install globally or wish to run a one-off execution without installing, use:
```
npx zklocus-oracle
```

Options for Executable

When running as an executable, you can pass options directly into the command to customize the server's behavior:

zklocus-oracle --ip=192.168.1.1 --port=3000 --endpoint=/api/signature

Npm Command

Alternatively, you can use npm scripts defined in the package.json to start the server. This method is typically used when you're working directly within the project directory and may include additional options for development.

Default Start

If you have not perfomed any custom configuration, the default endpoint is /. You can also use the --endpoint option to specify a custom endpoint.

Production Mode: To start the server in production mode with default configurations:
```
npm start
```
Custom Configuration: Customize the server's IP address, port, or endpoint:
```
npm start -- --ip=192.168.1.1 --port=3000 --endpoint=/api/signature
```

Development Mode

For development purposes, you may want to start the server with hot-reloading to see changes in real-time:

Hot Reload: Start the server in development mode with hot-reloading:
```
npm run dev
```
Custom Configuration: Just like the production mode, you can customize the IP, port, and endpoint:
```
npm run dev -- --ip=192.168.1.1 --port=3000 --endpoint=/api/signature
```

Sending Requests

Once the server is running, it's ready to receive geolocation signature requests. Use the following curl command to send a POST request with latitude and longitude data:

curl -X POST http://localhost:3000/api/signature -d '{"latitude": 34.0522, "longitude": -118.2437}'

Make sure to replace http://localhost:3000/api/signature with the actual address and port your server is running on, along with the correct endpoint if you've customized it.

If you have not provided the --endpoint argument, then the server will be running on the root endpoint /. If you have not provided the --port argument, then the server will be running on port 5577. As such, if you execute the server with npm start, npm run dev zklocus-oracle or npx zklocus-oracle without any arguments, then you can send a request to the oracle by using the following command:

curl -X POST http://localhost:5577 -d '{"latitude": 34.0522, "longitude": -118.2437}'

Receiving Responses

After sending a request, the server will respond with a JSON object containing the geolocation signature and the public key used for signing. Here's what you can expect:

{
  "signature": "signature_value_here",
  "publicKey": "public_key_used_here"
}

signature: The unique signature generated for the provided geolocation data.
publicKey: The public key associated with the private key used for signing. This key can be used to verify the signature's authenticity.

This updated usage section now provides a more detailed and clearer set of instructions covering both the direct executable method and the npm command run directly, ensuring users understand all available options for starting and interacting with the zkLocus Integration Oracle server.

zkLocus Deep(ish) Dive 🌐

What is zkLocus?

zkLocus is an innovative solution for authenticated private geolocation sharing, both off-chain and on-chain. It uses advanced cryptographic techniques to ensure that geolocation data is private, verifiable, and secure. By leveraging Zero-Knowledge proofs, specifically recursive zkSNARKs, zkLocus allows users to prove they are at a certain location without revealing the exact coordinates.

You can learn more about zkLocus in the following resources:

Key Features and Innovations

Recursive zkSNARKs: Allows for efficient and private verification of geolocation data.
Cross-Chain Compatibility: Works across different blockchain technologies, enhancing its applicability.
Off-Chain Capabilities: Ensures that geolocation data can be authenticated outside of the blockchain, broadening its use cases.
Native Rollup Functionality: Supports scalability and efficiency in verifying multiple geolocation proofs.

Use Cases

The potential applications for zkLocus are vast and varied. Here are just a few examples:

Supply Chain Verification: Ensuring that goods have traveled through the correct checkpoints.
Location-Based Access Control: Enhancing security by restricting access based on verifiable location data.
Enhanced Privacy for Location Services: Allowing users to prove location without sacrificing privacy.
Location-Based Smart Contracts: Enabling smart contracts to execute based on location data.
Location-Based Decentralized Finance (DeFi): Creation of geolocation-based derivatives and other financial instruments.

Development 🛠️

Development Setup

Setting up your development environment is straightforward. Ensure Node.js and npm are installed, then follow the installation guide.

Running Tests

The automated test suite for zkLocus Integration Oracle can be found in the zkLocus project. This oracle uses the public/end-user zkLocus API, which is tested under the zkLocus repository. You can find them at https://zklocus.dev.
