Background

The traditional insurance claim process for storm damage is often inefficient, opaque, and prone to delays and disputes. Property owners face challenges in getting timely inspections and fair assessments, while insurance providers struggle with fraud detection and cost management. Contractors and suppliers face payment delays and administrative burdens.

Blockchain technology offers a solution by providing a transparent, immutable record of all transactions and interactions, enabling smart contracts that automatically execute predefined conditions, and creating a token-based incentive system that aligns the interests of all participants.

Project Vision

The vision for this system is to create a seamless, transparent, and efficient platform that transforms the storm damage insurance claim process. By leveraging blockchain technology, the system aims to:

• Reduce claim processing time from weeks to days
• Increase transparency for all participants
• Ensure fair and accurate damage assessments
• Streamline payment processes through smart contracts
• Create economic incentives for quality service and timely completion
• Build trust between insurance providers, property owners, inspectors, and contractors

Document Purpose

This comprehensive documentation serves as a complete reference for the design, development, and implementation of the blockchain-based storm damage insurance claim system. It provides detailed specifications for all system components across three development stages, enabling developers, stakeholders, and investors to understand the system's architecture, functionality, and evolution.

Core Components

The system consists of several interconnected components:

Key Stakeholders

The system serves multiple stakeholders in the insurance ecosystem:

Development Stages

The system is designed to evolve through three distinct stages:

Each stage builds upon the previous one, adding new features and capabilities while maintaining backward compatibility.

Foundation Stage Overview

The Foundation Stage represents the minimal viable product (MVP) that demonstrates the core functionality of the blockchain-based storm damage insurance claim system. It focuses on essential features that provide immediate value to users while establishing a solid foundation for future development.

Claim Workflow

Smart Contract Architecture

// ClaimRegistry.sol
pragma solidity ^0.8.0;

contract ClaimRegistry {
    enum ClaimStatus { Initiated, InspectionScheduled, Assessed, Approved, InProgress, Completed }
    
    struct Claim {
        uint256 id;
        address propertyOwner;
        string propertyDetails;
        uint256 damageDate;
        ClaimStatus status;
        uint256 assessedAmount;
        uint256 deductibleAmount;
        address inspector;
        address contractor;
        string reportIPFSHash;
        uint256 createdAt;
        uint256 updatedAt;
    }
    
    mapping(uint256 => Claim) public claims;
    uint256 public claimCounter;
    
    event ClaimCreated(uint256 indexed claimId, address indexed propertyOwner);
    event ClaimStatusUpdated(uint256 indexed claimId, ClaimStatus status);
    
    function createClaim(string memory _propertyDetails, uint256 _damageDate) public returns (uint256) {
        claimCounter++;
        
        claims[claimCounter] = Claim({
            id: claimCounter,
            propertyOwner: msg.sender,
            propertyDetails: _propertyDetails,
            damageDate: _damageDate,
            status: ClaimStatus.Initiated,
            assessedAmount: 0,
            deductibleAmount: 0,
            inspector: address(0),
            contractor: address(0),
            reportIPFSHash: "",
            createdAt: block.timestamp,
            updatedAt: block.timestamp
        });
        
        emit ClaimCreated(claimCounter, msg.sender);
        return claimCounter;
    }
    
    function updateClaimStatus(uint256 _claimId, ClaimStatus _status) public {
        // Add access control and validation
        claims[_claimId].status = _status;
        claims[_claimId].updatedAt = block.timestamp;
        
        emit ClaimStatusUpdated(_claimId, _status);
    }
    
    // Additional functions for claim management...
}

The Foundation Stage implements a modular smart contract architecture with clear separation of concerns:

Interface Requirements

The Foundation Stage provides a web-based interface with the following key features:

The Foundation Stage interface is designed with responsive layouts to work across desktop and mobile devices, providing essential functionality while maintaining simplicity and ease of use.
