The authors developed InsureConnect, a system that uses blockchain technology to make property insurance claims after natural disasters more transparent and trustworthy. It stores property images off the blockchain but keeps proofs and records securely on a permissioned blockchain. The system uses new identity methods to register users and contracts and controls who can do what through special software rules. They tested how well it works with many users at once and found it handles increased demand fairly well, though things slow down and some connections fail when too many users try at once.

Abstract
This paper presents InsureConnect, a blockchain-based system for improving transparency, authentication, and auditability in property-insurance workflows after natural disasters. The system combines Self-Sovereign Identity (SSI), Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), satellite imagery, Hyperledger Fabric, and IPFS to register identities, insurance contracts, and damage claims. Property images are stored off-chain in IPFS, while content hashes and signed records are maintained on a permissioned blockchain. Users interact with the system through a desktop application, while chaincode enforces role-based access control and validates digital signatures. The prototype was evaluated under concurrent request loads from 50 to 3000 requests, measuring latency, throughput, and dropped connections. The results indicate that the system sustains increasing throughput under load, although latency rises and dropped connections appear at higher concurrency levels.
