Content Verification Sidechain

This project was bootstrapped with Klayr SDK This project implements a basic sidechain for content verification using the Klayr SDK. It allows users to submit content, verify it, and build reputation based on their submissions.

Project Overview

The Content Verification Sidechain is designed to:

• Allow users to submit content for verification
• Store submitted content securely
• Track user reputation based on their submissions
• Provide statistics on overall content submissions and verifications

Key Components

• ContentVerifierModule: The main module that orchestrates the content verification process.
• ContentStore: Stores submitted content entries.
• StatsStore: Keeps track of global statistics for content submissions and verifications.
• UserReputationStore: Manages user reputation data.
• CreateContentCommand: Handles the creation and storage of new content entries.
• ContentVerifierMethod: Implements methods for retrieving content, stats, and user reputation.
• ContentVerifierEndpoint: Exposes API endpoints for interacting with the sidechain.

Setup and Installation

Ensure you have Node.js and npm installed.

Clone the repository

git clone [repository-url]

Install dependencies

npm install

Build the project

npm run build

Running the Sidechain

Start a node

./bin/run start --config=config/custom_config.json

The node will be available by default at

http://localhost:7887

Interacting with the Sidechain

Here are some example commands to interact with the sidechain:

• NOTE that a passPhrase is needed to create the transaction.

Create content

./bin/run transaction:create contentVerifier createContent 10000000 --params='{"hash":"QmX4n5qKvqrA1JQFYqsdqhULtVXF6YHiH3CfDFX1YcBxEn", "userId":"user123", "timestamp":1633036800}' --json --pretty

Send the created transaction

./bin/run transaction:send <binary_transaction_output>

Verify Content:

./bin/run transaction:create contentVerifier verifyContent 10000000 --params='{"hash":"QmX4n5qKvqrA1JQFYqsdqhULtVXF6YHiH3CfDFX1YcBxEn"}' --json --pretty

Send the created transaction

./bin/run transaction:send <binary_transaction_output>

Get content

curl -X POST -H "Content-Type: application/json" -d @./test/api/getContent.json http://localhost:7887/rpc

Get stats

curl -X POST -H "Content-Type: application/json" -d @./test/api/getStats.json http://localhost:7887/rpc

Get user reputation

curl -X POST -H "Content-Type: application/json" -d @./test/api/getReputation.json http://localhost:7887/rpc

Future Improvements

• Implement more secure content verification logic
• Add more robust error handling and input validation
• Implement a proper consensus mechanism for block creation
• Add comprehensive testing
• Implement proper key management and user authentication
