Solidity State Machine with Git

This repository demonstrates how to create a simple Solidity state machine using Git for state management, smart contract storage, and ledger tracking in JavaScript. The example provides a basic setup for implementing a state machine using a Solidity smart contract, where the contract's state and transaction ledger are stored as JSON files and managed using Git commits.

Please note: This example is for educational purposes only and is not suitable for use in production environments. For real-world applications, consider using a more robust solution.

Design

The main exe is smartr.js this will operate on one or more data directories.

Each data directory contains

• ledger.json
• state.json
• contract.sol

Future versions will allow and quickjs contracts

Features

• Solidity smart contract for a simple state machine
• State and ledger stored in JSON files
• Git for versioning and tracking state and ledger changes

Prerequisites

• Node.js (v12.x or higher recommended)
• NPM (v6.x or higher recommended)
• Git

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/solidity-state-machine-git.git
   cd solidity-state-machine-git

2. Install the required packages:

   npm install

Usage

1. Create a Solidity smart contract (e.g., ./data/Example.sol) with the desired state machine logic.

   Example:

   pragma solidity ^0.8.0;
   
   contract Example {
       uint256 public value;
   
       function setValue(uint256 newValue) public {
           value = newValue;
       }
   }

2. Modify ./fastr.js` to reference the correct contract file and include any additional functions needed for your specific use case.

3. Initialize the Git repository and create the initial state and ledger files:

   git init
   mdkir data
   echo '{"value": 0}' > data/state.json
   echo '[]' > data/ledger.json
   git add data/state.json data/ledger.json
   git commit -m "Initial state and ledger"

4. Run the ./fastr.js` file to execute a function from the smart contract and update the state and ledger:

   ./smart.js [params]
