Welcome to SmartQueryBlockchain, an innovative project aiming to transform on-chain query execution within the blockchain ecosystem. This repository houses the codebase and documentation for the solution developed as part of the Data Analytics into Smart Contracts Hackathon (On-chain Query Execution).
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified, and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point, you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However, we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.

The challenge invites developers to pioneer a solution for executing complex queries directly on the blockchain. Our project focuses on empowering various sectors with real-time, data-driven decision-making capabilities through on-chain data.

Ensure you have the following tools and frameworks installed:
- Clone the repository: git clone https://github.com/yourusername/SmartQueryBlockchain.git cd SmartQueryBlockchain Install dependencies:
npm install npm install web3 npm install react-router-dom npm install @types/react-router-dom npm install react-search-input
- Configure Metamask:
Connect Metamask to your local Ganache blockchain.
- Compile and migrate smart contracts:
truffle compile truffle migrate
contracts/: Smart contract code
migrations/: Truffle migration scripts
tests/: Test scripts
docs/: Documentation files
Our solution comprises smart contracts that facilitate on-chain query execution. Key contracts include:
QueryExecutor.sol: Handles the execution of complex queries.
DataStorage.sol: Manages on-chain storage of relevant data.
Data is securely handled on-chain to ensure transparency and integrity. Off-chain storage is implemented with chosen technology such as MongoDB/AWS/HDFS/IPFS/HBase, providing a resilient way to retrieve information for smart contract execution.
We welcome contributions to enhance and refine our project. Follow these steps to contribute:
Fork the repository and create a new branch. Implement your feature or fix a bug. Ensure tests pass: truffle test Submit a pull request. Code Style Guidelines Adhere to the Solidity Style Guide for smart contract development.
