LockChain - a Lifetime Secret / Memory Keeper Dapp

This project is a decentralized application (Dapp) built using Golang, Solidity for smart contracts, and Next.js for the frontend. The Dapp focuses on securely storing and managing personal secrets or memories.

Tech Stack

• Smart Contract Language: Solidity
• Backend Language: Golang
• Frontend Framework: Next.js
• Development Tools: Truffle, Ganache, jq

Architecture

Getting Started

Prerequisites

1. Node.js: Ensure Node.js is installed. Download it from nodejs.org.
2. Truffle: Install Truffle globally:

   npm install -g truffle

3. jq: This project uses jq to process JSON files. Install jq based on your operating system:
   • Ubuntu/Debian:

     sudo apt-get install jq

   • macOS:

     brew install jq

   • Windows: Download jq from the jq releases page and follow the installation instructions.

Installation

1. Clone the Repository:

   git clone https://github.com/samarthasthan/lockchain.git

2. Install Dependencies: Navigate to the smart-contract directory and install the necessary dependencies:

   cd lifetime-secret-memory-keeper/smart-contract
   npm install

Build the Contract

1. Compile the Contract: Compile the smart contract with:

   truffle compile

   This generates compiled contract artifacts in the build/contracts/ directory.

Migrate the Contract

1. Deploy the Contract: Ensure you have a blockchain environment set up (e.g., Ganache, an Ethereum testnet). Deploy the contract using:

   truffle migrate --network development

   Replace development with your network configuration if needed.

Configuration

The truffle-config.js file contains configuration settings for Truffle, including network configurations and compiler settings. Modify this file according to your deployment environment.

Running Ganache CLI

To run Ganache CLI with a specific network ID and accounts configuration:

ganache-cli  --networkId 1337 --host 0.0.0.0 --port 8545

Additional Notes

• Environment Variables: Set up a .env file with necessary environment variables (e.g., private keys, Infura/Alchemy project IDs) if required by your configuration.
• Truffle Documentation: For more details on Truffle, refer to the Truffle documentation.

Troubleshooting

• Compilation Errors: Ensure your Solidity code is correct and compatible with the compiler version specified in truffle-config.js.
• Migration Issues: Check migration scripts and ensure your blockchain environment is properly set up.
