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

Clone the repository:

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

Install the required packages:
```
npm install
```

Usage

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;
    }
}

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

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"
